Really appreciate your videos. Over the last year, thanks to you, I've pimped out my a/c unit with a soft start kit and run it under light water mist on really hot days and it has helped immensely. Now our family has grown and we're buying a new house and I want to go through the new furnace completely thanks to this video. You've saved me a fair bit of money and really appreciate your knowledge.
Exactly. Save a couple dollars and ruin your coil. If you are trying to limp through a summer until you can save for replacement, fine. NEVER do this to a coil that you want to last. @@AndyDufresne4
My furnace wouldn't start, so I called a co. that advertised on a local religious channel. Thought they'd be honest? A guy came out and looked it over. Said electronic control panel was burnt. Obvious black flash mark on back. Said would be $900 to replace. I asked if anything else looked bad. Said no. He said wouldn't spend the $ on my 18 yo unit. Tried to sell me complete new system for $12k US. Looked up part online, bought for $200. TH-cam video for install. 5 years later, runs perfect. Crook. New sub.
As a gasfitter and a service technician, I like to watch other tech’s videos to see if I can learn something. I think this guy does a very good job, explaining how to service the furnace. However he could do a much better job explaining gas safety. Do not ever remove the test ports, or the manometer tube without first turning off the gas. In this situation it may not have been very dangerous because he is experienced and the type of test port doesn’t allow much gas through. A mid or low efficient gas valve however and you could have a massive ball of flames.
This needs to be bumped to the top. I just got done measuring the gas pressure on a unit where the test port has to be fully unthreaded. I should have known better than to do it running and it let a lot of gas out. Anyone else reading this, be careful and turn off the furnace when connecting and disconnecting the manometer.
This young man has saved THIS old man, a retired auto mechanic, a fortune taking care of my 29 year old furnace. I've learned so much from this man. You should watch his other videos! Straight to the point and tells you in layman's terms how to overcome complex issues that you may or may not understand. Probably most importantly, he talks about in several videos different ways you can get heat from your furnace if there is a power outage in your area. Very important in our troubled times. I'm still learning from him.
Same retired auto mechanic here who always likes to maintain his own appliances including HVAC. 29 year old AC condenser and 19 year old furnace still good. Learned a bit more from this great video. Saved thousands over the years because never had to call service company and get that immediate “You need a new furnace, AC, etc.” line from incompetent “repair” trainees.
I had Pestinger heating & Air conditioning of Salina Kansas come out to fix my furnace. It would stop working but when you put the cover back on it worked, but would shut down at night. They Replaced something and that night it quit working. Called them again came back out and replace the Hot Surface Control. Put it back together it worked. That night did the same thing and quit working. I'd already paid out hundreds and I was mad. Thinking what would cause it to not work but you miss with the furnace it would work. Sounded like something sticking. So I pulled out the book to the furnace got to looking. Turned out to be the Air Presser Switch. Ordered the part and it fixed it! That was several years ago. Man was I made. Been working on it myself every since! Just fixed another problem thanks to TH-cam videos like yours. Turns out there really not hard to work on. THANKS!
I have found through past experience never call the company with the big local advertisement for a furnace tune up special. Call the local company who has been in business for a very long time.
In my experience those burner units are not going to move out of the way that easily because they are connected to the gas line with iron pipe - so getting that out of the way is a bit more involved and maybe beyond what a DIY person wants to take on (removing gas fittings).
As a senior citizen on a fixed income, your videos are a Godsend. I don’t have loads of money but being retired, I do have the time to watch your videos and learn. You have already saved me money from an expensive callout. I cleaned the flame sensor and fixed the problem. My wife and I thank you. God bless you!
I would say the following are reasons your heater shuts off after being on for a little bit. #1 Flame Sensor (this part is under $5 to replace or free to clean off) #2 Capacitor for your blower motor is worn or old (this part is under $10 to replace). #3 The drip line hose is clogged or the filter leading to the drain is clogged with black gunk (this happened to me and was causing my heater to turn off and on since the inside was clogged with water that could not get out of the unit).
No one wants this guy to go anywhere, for every 1 viewer that “fixes” their unit 10 others will short something out and have to call a company anyways. I think people in my area watch him because they think staybrite can be used on existing copper. I’ve been going out and just doing braze and pump downs does not bother me one bit.
I've been in residential HVAC for just over 2 years and this is by far the best explanation on how to do a maintenance i've seen. I am curious tho can you explain whats wrong with the video? @@zavie22
As another mentioned below, i don't plan on doing my own maintenance, but i still appreciate the breakdown on the components and how things work. It's always best for homeowners to have some familiarity with everything in their home.
Your my new best friend....Im that guy , the one that fixes everything, except HVAC. Your tutorials are very explanatory and easy to follow. Not rushing out to do HVAC repairs but have enough knowledge to help out family and friends avoid the pitfalls of unscrupulous contractors who pray on the uneducated. Thanks for what you do , who you are, and the knowledge you share.
Great info. I’m a DIY guy, and I’ve done a lot of maintenance on my furnaces. I was not aware that u could just clean a flame sensor. I’m guilty of replacing them thinking they were defective. Oops.
Hi there , yes you can clean the flame sensor but only very lightly with very fine steel wool .I'm in Canada and its colder so I need to do this every second year .Please note after a few years the flame rod will need to be replaced.
Thanks. I replaced mine at 13 years not knowing I could clean it. So it is possible it was actually bad. I've replaced the hot surface ignitor (keep a spare), and the draft inducer motor. 16 years of use.
Very professional and well done summary. Recommend changing the title to something like” learn how to maintain your furnace like a pro.” Thank you for taking time to educate!
Great video. Straight forward, to the point and clearly explained every step. Watch your back though because the HVAC mafia is going to be after you. Started following you after the soft start install video. Didn't see that until the end of our AC season here in the NE so I'm going to wait and order one in the spring and install it then.
I actually have a new flame sensor in a ziplock bag duct taped to my furnace for that just in case day. Planning on buying a circuit board to also put in a freezer bag for standby. I priced it at about $150 and when I stupidly paid a company to clean my furnace they said a new installed board would run about $1400.
It is very very rare to replace a flame sensor. I have replaced 1 in the last 3 heating seasons. Just clean it once a year and you will be good. If I was you I would just get a capacitor for blower and outdoor unit. Probably a contactor for outside. Other than that save your money on the board and get a multi meter. Chances of correctly diagnosing a bad board with no meter or any other parts is slim
Thank you for these great tips on servicing a furnace. I will do this next week when the weather warms up a bit! Freezing weather has hit the Midwest over the last couple of days which is supposed to let up next week. I just implemented the "Keep Your Family Warm During A Power Outage By Installing This $5 Part" so my family is ready in the event of a power outage this winter". Thanks again Dave for all of these great tips.
We had our air con recharged and the HVAC guy was telling us stories where if he doesn't like the person a 20 minute job turns into over an hour. Dishonest much? Never calling that person again.
I have been cleaning and servicing my 2 gas furnaces for years after being scammed on a service call. This video is the BEST I've seen !! Thank you very much for the extra detail, guys like me need. Have all the tools, just need needed a little extra eg pull the blower to clean and check the amp draws. Best use of 25 mins I've spent in a while !
Excellent video. Thanks to info I’ve learned from your channel, I’ve installed a MicroAir soft start kit on my AC compressor, and next I’m going to service my furnace based on this video. I had 3 HVAC contractors come out earlier this summer to check out our system. They each suggested we replace our entire system, which is 15 years old, but works fine, with estimates ranging from 16k all the way up to 28k!
Same here. I purchased a house in 2019 that has a Munchkin natural gas boiler tied to a hydronic radiant floor system and indirect hot water tank. Installed in 2006. Of the 6 or so techs that have come out, only 1 has any idea what is going on and he is extremely expensive to do basic service. Now, Munchkin did go out of business so parts are a problem but I would think many are universal. All the techs, “This is a really old system. I’d replace it”. $17K-26K When I lived in New England most homes were radiant (old time radiators in each room) fueled by home heating oil. Those boilers were 50 plus years old and going strong. How can my boiler, which is 17 years old, need replacing? Anyway, I don’t have the $$$ even if I wanted to. I don’t understand the inherent dishonesty in the HVAC industry. Makes me lose faith in my fellow man. How can I live in an area of 750K people, hot housing market, and not be able to find a competent and honest HVAC company?
@@dukebeach1I work in residential for a large company. Company policy requires management to “encourage” techs to try and produce turnovers on jobs with older systems. Systems today will last about 10-15 years before getting replaced. It costs my company about 500 dollars just to send a tech out to the job. Just to SEND the tech to the house. Any turnovers to make up for that is desired. If we don’t at least plant the seed of a sale, and provide a record that we at least mention it to the homeowner, we can get penalized by the company. Most techs hate being told to sell things that don’t need replacing, and we’ve floated this to management, but it’s corporate policy. It’s not the techs fault, it’s the way the game is played these days, especially by larger companies.
Those old boilers you are referring to were made of cast iron or heavy gauge steel. That's why they can last so long. Even new cast iron and steel boilers aren't as durable as the older ones. They are made using less material. On most newer HVAC equipment, some parts are not universal. Munchkin boilers were not designed to last long.>@@dukebeach1
@@CrabtreeBob Well, I guess that is the case. I think I'm going to buy a bunch or parts now while I can to hopefully get as many years as possible out of my boiler. I found a supplier in CA that seems to have just about every part for my particular boiler. I'm sure they'er not OEM, but as long as they are an adequate substitute they should work. I can't imagine a spark ignitor or flame sensor is so different on my boiler than another make/model that aftermarket wont' do the trick. I suppose I'll find out.
This advice pertains to any kind of service, vehicle, HVAC, etc. Do your best to find a good honest tradesperson/technician, and give that person all your business. Let them know you appreciate them. Sadly, there are many people in all the various service industries who are not competent or honest. Take the time to do some research before you just call the first company in the phone directory, or take your vehicle to a shop. Even if you have no mechanical or electrical skills and don't plan to do the actual work, watching video's like this will help you know how stuff works and what you need to look for when checking someone's work. Never just show someone to the equipment and head back to the couch, stay with them and watch what they do. These video's are a public service.
Another thing that you can do when you have your furnace apart for cleaning is to get some duct masking paste and seal up the seams in the sheet metal box of the furnace. While you are at it, you can seal up a lot of the sheet metal seams and cabinet junctions.
Should also check the system static pressure and heat rise to verify that blower is set at the correct speed and that there are no obstructions in the system. You never know if the guy who installed the furnace really took the time to set the blower speed correctly.
Great information as usual. This was very informative and I love the props that you use to demonstrate sir. Really appreciate the help you provide for the DIY guys and the points you make when you should maybe call in the pros. Great job!
Thanks, Dave. Your instructions are detailed enough especially for people like me who never touched HVAC before. It would be great if you could do the same video for Goodman HVAC.
I discovered a massive condensate leak. This was 3 days after a brand new Carrier installation. The guys did not connect the exhaust as per the manual. There were several other flaws. I'm glad I knew what to look for or I'd be buying another new furnace in only a few years. I also made them set my gas pressures. They had to send a different guy.
Absolutely love that adding a plug was so easy. Now i feel comfortable knowing i can plug furnace into my Delta 2 , in case of a power outage .Thanks again
First things first Happy Thanksgiving to all on this channel. I need help, I installed A MrCool 36 K BTU Hyper heat system in my house two weeks ago. It is working fine with the thermostat that came with the unit. I would like to use my Nest (gen 3) thermostat instead. I would like to know how to wire it up for the Nest. If anyone can please help me that would be great. Thank you very much. Please Help.
My Heil is around 20 years old. Thanks to vids ive been able troubleshoot. Needless to say its got many new parts on it so its like new lol. Im no expert but overall ive discovered these things arent overly complicated. I did work commercial sheetmetal for 15 years but never learned service.
Thanks for the time and effort you take in making these videos. Your clarity in explaining each episode along with detailed video breaking down each task into to simple tasks is to be commended. Thanks for recommending the multi nut driver. I recently purchased one and the quality is excellent.
Awesome video, I appreciate someone like you that is so honest, I only wish that there would be more people like you in this business, ps keep up the great work 👍
I've watched the HVAC guy do maintenance on my furnace and they definitely didn't do all those things. They only checked a few amperage items, did a visual check of the burners and went on their way. Definitely going to DIY this next time.
I used to work in the HQ of a boiler manufacturer. The reason they want approved people to work on the boilers and inspect them is because DIY maintenance/install can be deadly. All of the deaths we had we due to customers trying to DIY or work that was done by people unfamiliar with our specific boilers. Stay safe.
(8:10) If cleaning the flame sensor electrode makes any difference, it may mean that the intermittent pilot controller is on its last legs and should be replaced. I was cleaning the electrode on mine several years ago because the furnace wasn't lighting reliably or staying lit and it let the furnace limp along for a few months, only to stop working completely in late winter. I spent several months in a cold house until I could find a replacement controller on eBay for a reasonable price, not something I wish to repeat.
I own and operate a small local HVAC company. I couldn’t agree with you more that there are companies out there that are seeking maintenance contracts specifically to try and sell you a product. Happy to say I started my own company so I didn’t have to participate in deceitful practices like this and so many more. We work of the old idea of helping our neighbors and community. Like you we educate and empower our clients to make the best decisions for them. We are here to provide a service not to sell a product. Huge difference. Thank you for posting this
You will not be able to scale your business unless you start down the path of sales. The numbers just don't work anymore. It's why private equity is going around snapping up independent HVAC shops. The industry is in turmoil right now, at least residential side of things.
I went to a service call the other day where someone recommended replacing a unit for a tripped limit on the blower housing. Easy fix and customer was pretty happy haha
Why would you thank him for posting that??????. How is it a good idea to encourage the general public to go meddling around in their gas heating system or air conditioning system for that matter..?? It's a horrendously bad idea.
@@NATHANFREDERICK-rs7yb - Because of all the scamming and lying from HVAC "technicians," it's good for him to THANK him for posting this content to help educate homeowners on doing much of this work for ourselves.
Thank you very much! most thorough inspection I've seen here on youtube! Got a question for you: I am at altitude in Colorado Springs, about 6,800 ft. I don't think my furnace was setup correctly. Flame is blue but I want to measure pressure. The manual for my carrier 58PAV has a table for adjustments at altitude and require knowing the gas "specific gravity" and the gas average heat value. I got the heat value from the gas company (963 BTU/cu ft) ) but they could not provide the specific gravity and gave me 'pressure' of 12.01 psia. I am looking at tables in the 58PAV manual. I am thinking my furnace is over-gassed. that is, the orifice nozzle is too big (factory sea level, #43) for this altitude and gas is being wasted because not enough air is able to combust it all. How can I figure out the exact specific gravity and tune this down? looking at the table for 6,000-7,000 ft altitude the pressure ranges are in the low 2.x and depending on the gravity some require #48 nozzles... Sorry too many specifics.. but how do I get to the bottom of this. I'm afraid if I call a local HVAC guy they won't have a clue. I am 99.9 convinced the new construction HVAC installer just looked at the panel and set this up to 3.x pressure and I am wasting gas and $$$.. This and if you could do a video for specific considerations for furnaces at altitude that would be AWESOME! I did the basics, cleaned the flame sensor, replaced the igniter (because it died), and cleaned the burners. proactively replaced the blower capacitor. Thanks, and thank you for your videos!!!! I've learned a LOT!
WOWZA! Many thanks from an 80 y/o DIY. Been working on all household and farm equipment since I was a kid. Like you point out: "You need the proper TOOLS!"
Very thorough. Thank you for this in-depth video of what a technician does when they inspect your furnace. The most important thing that I learned is that it's worth the $150 a year to get it done LOL
Excellent walk-through about critical maintenance steps for furnaces. You not only explained the various components in the system but also demonstrated the "how to" safely and efficiently. I had a classic failure of my Lennox 96% efficient furnace during the coldest time but it turned out to be a dirty flame sensor which I learned from one of your videos.
Im glad youre doing this. Im an apprentice plumber who started out working for a residential company that also does hvac. Theyre very predatory and use all kinds of psychological tricks to sell, and it works! Customers leave them a 5 star rating after getting ripped off.
love your videos and appreciate your honesty, and you prompted me to install my own furnace and everything went well,as i saved three thousand doing my own work.
I had the same local company maintain my 32 year old Rheem HVAC and they never tried to sell me anything. For $125 each year they do the PM on the entire system. After 32 years one of the motor bearings started to go and they gave me the cost to replace and for a new system. A no brainer going from 80% efficiency to 96, lower Btus due to home energy improvements (windows, insulation…) we have done over the years. Avoid the national franchise companies and go with the reputable local family owned businesses. You can’t go wrong.
Wow! You the best. I watched several videos but I didn’t understand. My thermostat was blank and I followed instructions of your video and immediately the AC started blowing/ cooling. Thanks so much
Very informative video thanks, but I don’t think it’s “as easy as that” for everyone 😅 some of those steps are a little complicated to accomplish, even for a DIYer
Great video! Have appreciated how much I’ve learned through your step by step videos. Have shared with friends for future. Thanks for your time and commitment. Invaluable info!
I loved family danz went to my mom’s house.. broke the pvc pipe for intake care and wanted to charge them 700$ in repairs. I told them to get the hell out and repaired it for 10$…
Hey Mr DIY HVAC GUY Recently moved into a fairly new home (5yr old) w/a horizontal Goodman unit in the walk-in attic (original install). Realized there was no way to change the filter nor any access to it. Researched the unit online & found the installers had covered the access panel up at the intake end (where the silver puffy venting stuff attaches) w/ a masting adhesive w/foil tape underneath (WTH?). So, I cut a slit where I knew it should be & uncovered/unscrewed the panel. No filter was ever installed apparently & why they covered it all up. Is this bad for the unit? I taped it back up with foil tape super well so there's no air leaks. Is this normal or a good idea? While I've had no issues, I just want to make sure it doesn't shorten the life of this 5 yr old/newer unit. First home I've bought that DIDN'T need a new HVAC as soon as I moved in and then I find this. Appreciate your thoughts on this or anyone in the chat. Love your channel & long time subscriber in Georgia.
Lol can’t wait for you DIY people to try all this and then call me when you frick something up. This guy has something out for techs because y’all can learn this stuff but don’t mess with it.. CALL A PROFESSIONAL.
I have a 22 yr. old York that's still working good but obviously getting old. I live in SoCal but some years it can get to the low to mid 30's for a few days in Dec./Jan. My HVAC guy is pushing a heat pump for a new install. What is your feeling on heat pumps, are they as reliable as a standard furnace/air conditioner and what brand should I be considering? He says he likes American Standard. Thoughts?
I'm in the process of buying a house from a friend. His mother passed away about 12 years ago and house has sat. Trane furnace. Local HVAC co came out to check and said need all new systems. AC and furnace. They are original units from 1993 but were only used about 10 years in mild NC climate. Quotes for new systems are $9,000.oo
I would just like to say, you sir are a nation treasure! I am incredibly grateful for the content you put out there. I myself am very mechanically inclined, and prefer to do stuff myself, and these kind of videos help a lot in making sure I am dotting my I’s and crossing my T’s. Keep making these great videos!!!
Here's a HVAC Advice: if you are not sure if you have a crack Heat Exchanger by looking, you can check by using a stove lighter with one simple trick. Allow power back to the unit and on the thermostat, switch the fan switch to on. The fan will run, blowing across the Heat Exchanger. If the Heat Exchanger has a crack, air will be forced into it. You ignite the stove lighter and carefully put it inside the heat exchanger, if you see the flame flicker a lot or lose it flame then yes, the Heat Exchanger is crack or rusted out.
follow-up diagnose: When the thermostat shuts furnace down it will not fire back up when called for but, if I unplug the furnace during cycle, then plug in at later time it will fire up. Is this problem contained in the ignition control board. Have already compared old existing coils with new coils -- same reading. Any other Ideas for me to check? ( Suburban Aire direct vent ng furnace/heater 40,000 btu
Hello I love your content I have an issue with my Napoleon 2020 9700 series furnace. The furnace is Surging ,Cycling the air . It doesn’t do it all the time. I noticed it more when the AC is in service . Any idea on why it is doing this ? Thank you !!
Lol, you can't watch a TH-cam video and service equipment like a Tech with decades of experience and training. This weeks news had two elderly people die from there furnace running away and wouldn't shut off.... They had just had a family member "Service" there system to save money Don't want to get ripped off? Build a relationship with a local company and use the same one every time
Having the burner going while removing/attaching the manometer tube and trying to quickly close/open the test port is a good way for someone to get killed, turn gas off and do such operation with the furnace inop. I just bought my buddy a new flame sensor, was around $25-30 my cost. Cleaning it with a wire brush is no bueno per manufacturers. You didn't talk about the drain trap in the video, probably the easiest model to remove trap/burners/blower on.
Telling people they don’t need a furnace serviced by a pro is pretty irresponsible! Not all HVAC companies are crooked! Every single furnace manufacturer requires they be properly serviced. Not just cleaning but checking it throughly for safety! Very very few homeowners have the proper tools or knowledge to do these things! And frankly you are showing them somethings that may get them hurt or worse! You only showed a portion of a proper servicing. Hope you have good liability insurance
I already commented on one of the videos, but will do it again. Again, you are not " taking money from bad guys trying to rip you off " Thus " repairs" by homeowner can create disaster. People who follow these recommendations and have no clue,can do more harm than profit to themselves. Yes, many can remove burner and replace flame sensor per say, but how they are going to check if everything functional right? Manifold pressure is right? Or maybe, there is dangerous condition caused by defective heat exchanger? Trust me,I saw many guys keep reseting rollout switch with holes in heat exchanger. They red about it on internet, and this can be going very bad. Please, use your common sense. You can check your air filter or see if breaker tripped before calling tech. Beyond that, leave to professional.
This isn’t stuff you should be showing the public. Too easy to make a mistake without noticing it. Also recommending someone to get 3 opinions for an issue is just throwing money away companies don’t do that for free. Also you tried to sell product throughout this video. Please use your brain and have some respect for your craft.
Would you ever consider doing the maintenance on a Lennox Pulse Furnace. I realize mine is older, but I continue to have excellent service from this furnace. (I always have a CO monitor near my furnace.) My current self maintenance includes oiling the blower and changing the air inlet flapper valve periodically. (And the filter of course…) Thanks
This is a good video for a new service tech. Although I'm not a fan of checking gas pressure while the burners are lit right by the set screw. Homeowners.. don't touch anything. Change ur filter..clean ur flame senser if u want n check blower bearings and capacitor if u want but thats all I'd touch on this furnace. N service techs just blow out burner dust w CO2 tank. Removing manifold is more difficult with black iron gas pipe going into unit as opposed to flex pipe.
I never learned a detailed explanation on Furnance. Last winter in dec 2022 my furnace was not heating .The furnace was under repair contract. The contractor showed up and said pcb board is not working. It will take a week to get from manufacturer and ask the company sales person to advise on new furnance. The sales erson quoted for 5000 dollars . See how these companies traps their customers . I called a local person in Mississauga, Canada. He provided for $ 3000 a new six burners furnance and replaced next day. The ordered parts pcb came after 3 days only. The old furnce was tyrant 3 burned installed in 2004. The contractor name is Reliance . So this company is more efficient in selling product than doing maintenance and keeping spare parts
😆 had a HVAC guy come do a secondary inspection on my furnace after my home inspection on a home I sold. Of course he found my heat exchanger was cracked. I paid a different contractor to replace the unit. Once we got the old unit removed my HVAC contractor showed me where he scratched the heat exchanger with a screw driver to make it look like a crack. After closing on my house sale we found out the HVAC guy who did this was the uncle to the kid buying my house! They both worked for a very respected HVAC company in my area as well! HVAC guys are shady!
I WANT to have an expert come and fix my Rinnai, but no one will and the techs at Rinnai cant fix it. Im sticking with oil and gas boilers. They are stoopid simple and go forever. These new 98% efficient, computer controlled, direct fired units suck and cost way more since you got to replace them every 3 years or more.
My coaches ceiling mounted heater randomly stopped working one morning. He called a guy to come check it out. Tech shows up, take a small panel off. Cleans some dust off a relay switch then turned it back on. It was just dusty around the switch. Heater has been working fine for 5 years now. That call cost cost him $275 for the tech just to show up and basically flick a switch.
Question with modern high efficiency furnaces is it necessary to call 2nd stage heating to ensure your inducer and blower motors and valve are at full title before checking current draw? I think you would need to jump W1, W1 and R?
Good luck in your next evolution. I will be watching. Got my Universal epa rating on skillcat (when it was free) thx to you. Have learned a lot from your videos- even installed a soft start on my a/c system to decrease inrush amps now that I added an EV charger on the same panel. If it exists already please let me know , but I would love to see a video that explains the meanings of the wire lettering in thermostats and on the control boards. THX
15 yr old gas furnace.What should be done if the inducer, the big plastic thing is pulling double the amps? I do have lots of dust on the blower fan, and the blower motor is leaking oil and over amperage probably because of dust on blower. I also have leaks on the air exchanger.
First, Thank you for a well done educative video. I have a pretty new furnace, about 10 year old. I always had the same company doing the maintenance, always requested the same technician, but the company ended up sending someone else to do the scheduled maintenance. Within a couple weeks I noticed the warm shower water goes from hot to cold while taking a shower, then a couple days later the heat was off when i checked the furnace there was a big water leak. My question is what caused that leak? Just to be preventive about it. I have propane, and the furnace is a New Yorker
That’s not true that it’s rare carbon monoxide comes out of the heater. I have proved and documented it multiple times with both residential and commercial equipment ultimately resulting in shutting the equipment down.
Carbon monoxide virtually never exits the “crack” it comes from the burners inlet ports. The pressure the blower puts into the heat exchanger reduces the draft in the heat exchanger prior to the crack. Generally long before the draft is reduced to the point of the flame rolling out the exhaust fumes (along with CO) will proceed the that flame. A lot of the time you’ll see discoloration / soot around the burner box area when this is happening even though you never actually see the flame touch those areas but soot from the fumes are still present. Personally if you see anything that’s “odd” I’d call a professional. Call around to friends to find a company you trust. Then have the tech explain the oddity, if he can’t call someone else.

Really appreciate your videos. Over the last year, thanks to you, I've pimped out my a/c unit with a soft start kit and run it under light water mist on really hot days and it has helped immensely. Now our family has grown and we're buying a new house and I want to go through the new furnace completely thanks to this video. You've saved me a fair bit of money and really appreciate your knowledge.
Thanks man! Happy the videos are helping people out 😊
How much as the mister saved you?
@@aaronw6706The real question is, how much WILL it cost him?
Exactly. Save a couple dollars and ruin your coil. If you are trying to limp through a summer until you can save for replacement, fine. NEVER do this to a coil that you want to last. @@AndyDufresne4
The other question is, how much money are the unscrupulous HVAC people lost?
My furnace wouldn't start, so I called a co. that advertised on a local religious channel. Thought they'd be honest? A guy came out and looked it over. Said electronic control panel was burnt. Obvious black flash mark on back. Said would be $900 to replace. I asked if anything else looked bad. Said no. He said wouldn't spend the $ on my 18 yo unit. Tried to sell me complete new system for $12k US. Looked up part online, bought for $200. TH-cam video for install. 5 years later, runs perfect. Crook. New sub.
As a gasfitter and a service technician, I like to watch other tech’s videos to see if I can learn something. I think this guy does a very good job, explaining how to service the furnace. However he could do a much better job explaining gas safety. Do not ever remove the test ports, or the manometer tube without first turning off the gas. In this situation it may not have been very dangerous because he is experienced and the type of test port doesn’t allow much gas through. A mid or low efficient gas valve however and you could have a massive ball of flames.
This needs to be bumped to the top. I just got done measuring the gas pressure on a unit where the test port has to be fully unthreaded. I should have known better than to do it running and it let a lot of gas out. Anyone else reading this, be careful and turn off the furnace when connecting and disconnecting the manometer.
This young man has saved THIS old man, a retired auto mechanic, a fortune taking care of my 29 year old furnace. I've learned so much from this man. You should watch his other videos! Straight to the point and tells you in layman's terms how to overcome complex issues that you may or may not understand. Probably most importantly, he talks about in several videos different ways you can get heat from your furnace if there is a power outage in your area. Very important in our troubled times. I'm still learning from him.
Same retired auto mechanic here who always likes to maintain his own appliances including HVAC. 29 year old AC condenser and 19 year old furnace still good. Learned a bit more from this great video. Saved thousands over the years because never had to call service company and get that immediate “You need a new furnace, AC, etc.” line from incompetent “repair” trainees.
Thanks for sharing! And thanks for the kind words. Comments like these are why I do what I do 👊🏼
Same here too! Nailed it.
I had Pestinger heating & Air conditioning of Salina Kansas come out to fix my furnace. It would stop working but when you put the cover back on it worked, but would shut down at night. They Replaced something and that night it quit working. Called them again came back out and replace the Hot Surface Control. Put it back together it worked. That night did the same thing and quit working. I'd already paid out hundreds and I was mad. Thinking what would cause it to not work but you miss with the furnace it would work. Sounded like something sticking. So I pulled out the book to the furnace got to looking. Turned out to be the Air Presser Switch. Ordered the part and it fixed it! That was several years ago. Man was I made. Been working on it myself every since! Just fixed another problem thanks to TH-cam videos like yours. Turns out there really not hard to work on. THANKS!
I have found through past experience never call the company with the big local advertisement for a furnace tune up special. Call the local company who has been in business for a very long time.

Same rule goes for car body shops!!
@@tretre1692Most big shops are in bed with the insurance companies! Basically they buy their work!
Yeah. Just like the guys want to sell you a brand new water heater instead of replacing a thermocouple.
How do I find such a long time business?
In my experience those burner units are not going to move out of the way that easily because they are connected to the gas line with iron pipe - so getting that out of the way is a bit more involved and maybe beyond what a DIY person wants to take on (removing gas fittings).
Should be a valve and a union. Only fitting you have to remove is the one designed to be taken apart.
As a senior citizen on a fixed income, your videos are a Godsend. I don’t have loads of money but being retired, I do have the time to watch your videos and learn. You have already saved me money from an expensive callout. I cleaned the flame sensor and fixed the problem. My wife and I thank you. God bless you!
Welder/Fabricator here - thanks for all you do. This is one fine side of youtube. Thanks for helping out average folk
If I lived in your area, I'd hire you in a heartbeat. Thanks for all you do!
He's focusing on TH-cam
I would say the following are reasons your heater shuts off after being on for a little bit. #1 Flame Sensor (this part is under $5 to replace or free to clean off) #2 Capacitor for your blower motor is worn or old (this part is under $10 to replace). #3 The drip line hose is clogged or the filter leading to the drain is clogged with black gunk (this happened to me and was causing my heater to turn off and on since the inside was clogged with water that could not get out of the unit).
Surprised HVAC contractors havent tried to have you disappeared for the great value of the info you share. Thanks for doing this.
No one wants this guy to go anywhere, for every 1 viewer that “fixes” their unit 10 others will short something out and have to call a company anyways. I think people in my area watch him because they think staybrite can be used on existing copper. I’ve been going out and just doing braze and pump downs does not bother me one bit.
great video, as a 2nd year residential hvac apprentice this was very helpful to understand how to do a maintenance better. Thank You
Seriously you dont know how to dona maintenance you watch a non hvac person lmao
I've been in residential HVAC for just over 2 years and this is by far the best explanation on how to do a maintenance i've seen. I am curious tho can you explain whats wrong with the video? @@zavie22
@@zavie22 and you don't know how to spell correctly lmao !
As another mentioned below, i don't plan on doing my own maintenance, but i still appreciate the breakdown on the components and how things work. It's always best for homeowners to have some familiarity with everything in their home.
Your my new best friend....Im that guy , the one that fixes everything, except HVAC. Your tutorials are very explanatory and easy to follow. Not rushing out to do HVAC repairs but have enough knowledge to help out family and friends avoid the pitfalls of unscrupulous contractors who pray on the uneducated. Thanks for what you do , who you are, and the knowledge you share.
Great info. I’m a DIY guy, and I’ve done a lot of maintenance on my furnaces. I was not aware that u could just clean a flame sensor. I’m guilty of replacing them thinking they were defective. Oops.
Hi there , yes you can clean the flame sensor but only very lightly with very fine steel wool .I'm in Canada and its colder so I need to do this every second year .Please note after a few years the flame rod will need to be replaced.
Thanks. I replaced mine at 13 years not knowing I could clean it. So it is possible it was actually bad. I've replaced the hot surface ignitor (keep a spare), and the draft inducer motor. 16 years of use.
Very professional and well done summary. Recommend changing the title to something like” learn how to maintain your furnace like a pro.” Thank you for taking time to educate!
Great video. Straight forward, to the point and clearly explained every step. Watch your back though because the HVAC mafia is going to be after you.
Started following you after the soft start install video. Didn't see that until the end of our AC season here in the NE so I'm going to wait and order one in the spring and install it then.
I actually have a new flame sensor in a ziplock bag duct taped to my furnace for that just in case day. Planning on buying a circuit board to also put in a freezer bag for standby. I priced it at about $150 and when I stupidly paid a company to clean my furnace they said a new installed board would run about $1400.
Sounds about right
You should also carry a spare hot surface ignitor
In my world that board would cost you $500 ish diagnosed & installed.
It is very very rare to replace a flame sensor. I have replaced 1 in the last 3 heating seasons. Just clean it once a year and you will be good. If I was you I would just get a capacitor for blower and outdoor unit. Probably a contactor for outside. Other than that save your money on the board and get a multi meter. Chances of correctly diagnosing a bad board with no meter or any other parts is slim
Thank you for these great tips on servicing a furnace. I will do this next week when the weather warms up a bit! Freezing weather has hit the Midwest over the last couple of days which is supposed to let up next week.
I just implemented the "Keep Your Family Warm During A Power Outage By Installing This $5 Part" so my family is ready in the event of a power outage this winter". Thanks again Dave for all of these great tips.
🙌🏼🙌🏼🤘🏼🤘🏼
Thanks for sharing your experience and tricks of trades. I would be really scared to do something like this. Thanks again.
We had our air con recharged and the HVAC guy was telling us stories where if he doesn't like the person a 20 minute job turns into over an hour. Dishonest much? Never calling that person again.
Can you do an updated video on UVC lights in duct work? There are lots of those lights out there now...... I'm always learning from your vids!
I have been cleaning and servicing my 2 gas furnaces for years after being scammed on a service call.
This video is the BEST I've seen !!
Thank you very much for the extra detail, guys like me need. Have all the tools, just need needed a little extra eg pull the blower to clean and check the amp draws.
Best use of 25 mins I've spent in a while !
Excellent video. Thanks to info I’ve learned from your channel, I’ve installed a MicroAir soft start kit on my AC compressor, and next I’m going to service my furnace based on this video. I had 3 HVAC contractors come out earlier this summer to check out our system. They each suggested we replace our entire system, which is 15 years old, but works fine, with estimates ranging from 16k all the way up to 28k!
Same here. I purchased a house in 2019 that has a Munchkin natural gas boiler tied to a hydronic radiant floor system and indirect hot water tank. Installed in 2006.
Of the 6 or so techs that have come out, only 1 has any idea what is going on and he is extremely expensive to do basic service.
Now, Munchkin did go out of business so parts are a problem but I would think many are universal.
All the techs, “This is a really old system. I’d replace it”. $17K-26K
When I lived in New England most homes were radiant (old time radiators in each room) fueled by home heating oil. Those boilers were 50 plus years old and going strong.
How can my boiler, which is 17 years old, need replacing? Anyway, I don’t have the $$$ even if I wanted to.
I don’t understand the inherent dishonesty in the HVAC industry. Makes me lose faith in my fellow man.
How can I live in an area of 750K people, hot housing market, and not be able to find a competent and honest HVAC company?
@@dukebeach1I work in residential for a large company. Company policy requires management to “encourage” techs to try and produce turnovers on jobs with older systems. Systems today will last about 10-15 years before getting replaced. It costs my company about 500 dollars just to send a tech out to the job. Just to SEND the tech to the house. Any turnovers to make up for that is desired. If we don’t at least plant the seed of a sale, and provide a record that we at least mention it to the homeowner, we can get penalized by the company. Most techs hate being told to sell things that don’t need replacing, and we’ve floated this to management, but it’s corporate policy. It’s not the techs fault, it’s the way the game is played these days, especially by larger companies.
Those old boilers you are referring to were made of cast iron or heavy gauge steel. That's why they can last so long. Even new cast iron and steel boilers aren't as durable as the older ones. They are made using less material. On most newer HVAC equipment, some parts are not universal. Munchkin boilers were not designed to last long.>@@dukebeach1
@@CrabtreeBob Well, I guess that is the case. I think I'm going to buy a bunch or parts now while I can to hopefully get as many years as possible out of my boiler. I found a supplier in CA that seems to have just about every part for my particular boiler. I'm sure they'er not OEM, but as long as they are an adequate substitute they should work. I can't imagine a spark ignitor or flame sensor is so different on my boiler than another make/model that aftermarket wont' do the trick. I suppose I'll find out.
This advice pertains to any kind of service, vehicle, HVAC, etc. Do your best to find a good honest tradesperson/technician, and give that person all your business. Let them know you appreciate them. Sadly, there are many people in all the various service industries who are not competent or honest. Take the time to do some research before you just call the first company in the phone directory, or take your vehicle to a shop. Even if you have no mechanical or electrical skills and don't plan to do the actual work, watching video's like this will help you know how stuff works and what you need to look for when checking someone's work. Never just show someone to the equipment and head back to the couch, stay with them and watch what they do. These video's are a public service.
Another thing that you can do when you have your furnace apart for cleaning is to get some duct masking paste and seal up the seams in the sheet metal box of the furnace. While you are at it, you can seal up a lot of the sheet metal seams and cabinet junctions.
The few you could reach 🤔
O
Should also check the system static pressure and heat rise to verify that blower is set at the correct speed and that there are no obstructions in the system. You never know if the guy who installed the furnace really took the time to set the blower speed correctly.
Great information as usual. This was very informative and I love the props that you use to demonstrate sir. Really appreciate the help you provide for the DIY guys and the points you make when you should maybe call in the pros. Great job!
Thanks, Dave. Your instructions are detailed enough especially for people like me who never touched HVAC before. It would be great if you could do the same video for Goodman HVAC.
If you're new to fixing a machine of any kind, take pictures of how the wires are connected before you start unplugging things
What differences do I need to look out for if our furnace is an LP conversion?
Different spring in gas valve for higher pressure and larger orifices that's it.
I discovered a massive condensate leak. This was 3 days after a brand new Carrier installation. The guys did not connect the exhaust as per the manual. There were several other flaws. I'm glad I knew what to look for or I'd be buying another new furnace in only a few years. I also made them set my gas pressures. They had to send a different guy.
Absolutely love that adding a plug was so easy. Now i feel comfortable knowing i can plug furnace into my Delta 2 , in case of a power outage .Thanks again
Is it also a good idea to shut off the gas flow to the furnace off!🤔
Yes, this one didn’t have a valve but if you are messing with gas you should shut the valve just in case.
@diyhvacguy Thank you so much.
First things first Happy Thanksgiving to all on this channel. I need help, I installed A MrCool 36 K BTU Hyper heat system in my house two weeks ago. It is working fine with the thermostat that came with the unit. I would like to use my Nest (gen 3) thermostat instead.
I would like to know how to wire it up for the Nest. If anyone can please help me that would be great. Thank you very much. Please Help.
Can someone help me??????
My Heil is around 20 years old. Thanks to vids ive been able troubleshoot. Needless to say its got many new parts on it so its like new lol. Im no expert but overall ive discovered these things arent overly complicated. I did work commercial sheetmetal for 15 years but never learned service.
Thanks for the time and effort you take in making these videos. Your clarity in explaining each episode along with detailed video breaking down each task into to simple tasks is to be commended. Thanks for recommending the multi nut driver. I recently purchased one and the quality is excellent.
No thanks necessary, TH-cam compensates him nicely
Excellent video! Even though I may not do the maintenance, at least I know what service items are required.
Awesome video, I appreciate someone like you that is so honest, I only wish that there would be more people like you in this business, ps keep up the great work 👍
I've watched the HVAC guy do maintenance on my furnace and they definitely didn't do all those things. They only checked a few amperage items, did a visual check of the burners and went on their way. Definitely going to DIY this next time.
Or you could hire a honest tech like me...Good luck !
HVAC guy hate you , but I live you
Appreciate
Wow ! We've actually had service contracts , and the techs are in and out in minutes!! They seem agitated if we ask questions! Where are you located?
Salt Lake City, Ut
I used to work in the HQ of a boiler manufacturer. The reason they want approved people to work on the boilers and inspect them is because DIY maintenance/install can be deadly. All of the deaths we had we due to customers trying to DIY or work that was done by people unfamiliar with our specific boilers. Stay safe.
Thank you for such an informative video. Clear and precise.
Thanks couldn’t do all that, but your class put me in the game talking to people.
(8:10) If cleaning the flame sensor electrode makes any difference, it may mean that the intermittent pilot controller is on its last legs and should be replaced. I was cleaning the electrode on mine several years ago because the furnace wasn't lighting reliably or staying lit and it let the furnace limp along for a few months, only to stop working completely in late winter. I spent several months in a cold house until I could find a replacement controller on eBay for a reasonable price, not something I wish to repeat.
I own and operate a small local HVAC company. I couldn’t agree with you more that there are companies out there that are seeking maintenance contracts specifically to try and sell you a product. Happy to say I started my own company so I didn’t have to participate in deceitful practices like this and so many more. We work of the old idea of helping our neighbors and community. Like you we educate and empower our clients to make the best decisions for them. We are here to provide a service not to sell a product. Huge difference. Thank you for posting this
You will not be able to scale your business unless you start down the path of sales. The numbers just don't work anymore. It's why private equity is going around snapping up independent HVAC shops. The industry is in turmoil right now, at least residential side of things.
I went to a service call the other day where someone recommended replacing a unit for a tripped limit on the blower housing. Easy fix and customer was pretty happy haha

Got a question for you: I am at altitude in Colorado Springs, about 6,800 ft. I don't think my furnace was setup correctly. Flame is blue but I want to measure pressure. The manual for my carrier 58PAV has a table for adjustments at altitude and require knowing the gas "specific gravity" and the gas average heat value. I got the heat value from the gas company (963 BTU/cu ft) ) but they could not provide the specific gravity and gave me 'pressure' of 12.01 psia. I am looking at tables in the 58PAV manual.
I am thinking my furnace is over-gassed. that is, the orifice nozzle is too big (factory sea level, #43) for this altitude and gas is being wasted because not enough air is able to combust it all.
How can I figure out the exact specific gravity and tune this down? looking at the table for 6,000-7,000 ft altitude the pressure ranges are in the low 2.x and depending on the gravity some require #48 nozzles...
Sorry too many specifics.. but how do I get to the bottom of this. I'm afraid if I call a local HVAC guy they won't have a clue. I am 99.9 convinced the new construction HVAC installer just looked at the panel and set this up to 3.x pressure and I am wasting gas and $$$..
This and if you could do a video for specific considerations for furnaces at altitude that would be AWESOME!
I did the basics, cleaned the flame sensor, replaced the igniter (because it died), and cleaned the burners. proactively replaced the blower capacitor.
Thanks, and thank you for your videos!!!! I've learned a LOT!
Awesome! Thank you so much for this simple tutorial.At least we can be informed consumers of HVAC services.
WOWZA! Many thanks from an 80 y/o DIY. Been working on all household and farm equipment since I was a kid. Like you point out: "You need the proper TOOLS!"
Right tools and common sense make wonders!
Very thorough. Thank you for this in-depth video of what a technician does when they inspect your furnace.
The most important thing that I learned is that it's worth the $150 a year to get it done LOL
Excellent walk-through about critical maintenance steps for furnaces. You not only explained the various components in the system but also demonstrated the "how to" safely and efficiently. I had a classic failure of my Lennox 96% efficient furnace during the coldest time but it turned out to be a dirty flame sensor which I learned from one of your videos.
Im glad youre doing this. Im an apprentice plumber who started out working for a residential company that also does hvac. Theyre very predatory and use all kinds of psychological tricks to sell, and it works! Customers leave them a 5 star rating after getting ripped off.
I do this myself, but you taught me an extra few steps to do. Thank you. Goodman propane 5 burner 120k BTU with AC option over the furnace.
love your videos and appreciate your honesty, and you prompted me to install my own furnace and everything
went well,as i saved three thousand doing my own work.
Did you need a permit or inspection?
I had the same local company maintain my 32 year old Rheem HVAC and they never tried to sell me anything. For $125 each year they do the PM on the entire system. After 32 years one of the motor bearings started to go and they gave me the cost to replace and for a new system. A no brainer going from 80% efficiency to 96, lower Btus due to home energy improvements (windows, insulation…) we have done over the years. Avoid the national franchise companies and go with the reputable local family owned businesses. You can’t go wrong.
You got it right mate. Then you get a guy like me come out.
Very thorough maintenance check. I doubt very many service techs are that thorough. Good job I would want somebody like you working on my HVAC.
Wow! You the best. I watched several videos but I didn’t understand. My thermostat was blank and I followed instructions of your video and immediately the AC started blowing/ cooling. Thanks so much
Very informative video thanks, but I don’t think it’s “as easy as that” for everyone 😅 some of those steps are a little complicated to accomplish, even for a DIYer
Great video! Have appreciated how much I’ve learned through your step by step videos. Have shared with friends for future. Thanks for your time and commitment. Invaluable info!

Hey Mr DIY HVAC GUY
Recently moved into a fairly new home (5yr old) w/a horizontal Goodman unit in the walk-in attic (original install). Realized there was no way to change the filter nor any access to it. Researched the unit online & found the installers had covered the access panel up at the intake end (where the silver puffy venting stuff attaches) w/ a masting adhesive w/foil tape underneath (WTH?). So, I cut a slit where I knew it should be & uncovered/unscrewed the panel. No filter was ever installed apparently & why they covered it all up. Is this bad for the unit? I taped it back up with foil tape super well so there's no air leaks. Is this normal or a good idea? While I've had no issues, I just want to make sure it doesn't shorten the life of this 5 yr old/newer unit. First home I've bought that DIDN'T need a new HVAC as soon as I moved in and then I find this. Appreciate your thoughts on this or anyone in the chat. Love your channel & long time subscriber in Georgia.
We must protect this man at all costs.
You da man.
Great learning and cost saving tips. Your videos rock. Thanks

I have a 22 yr. old York that's still working good but obviously getting old. I live in SoCal but some years it can get to the low to mid 30's for a few days in Dec./Jan. My HVAC guy is pushing a heat pump for a new install. What is your feeling on heat pumps, are they as reliable as a standard furnace/air conditioner and what brand should I be considering? He says he likes American Standard. Thoughts?
I'm in the process of buying a house from a friend. His mother passed away about 12 years ago and house has sat. Trane furnace. Local HVAC co came out to check and said need all new systems.

I myself am very mechanically inclined, and prefer to do stuff myself, and these kind of videos help a lot in making sure I am dotting my I’s and crossing my T’s. Keep making these great videos!!!
Here's a HVAC Advice: if you are not sure if you have a crack Heat Exchanger by looking, you can check by using a stove lighter with one simple trick. Allow power back to the unit and on the thermostat, switch the fan switch to on. The fan will run, blowing across the Heat Exchanger. If the Heat Exchanger has a crack, air will be forced into it. You ignite the stove lighter and carefully put it inside the heat exchanger, if you see the flame flicker a lot or lose it flame then yes, the Heat Exchanger is crack or rusted out.
Never knew spider webs and/or spider's nest can plaque as a factor from having the HVAC performing correctly. Until now... Facts!
follow-up diagnose: When the thermostat shuts furnace down it will not fire back up when called for but, if I unplug the furnace during cycle, then plug in at later time it will fire up. Is this problem contained in the ignition control board. Have already compared old existing coils with new coils -- same reading. Any other Ideas for me to check?

Hello
I love your content
I have an issue with my Napoleon 2020 9700 series furnace.
The furnace is Surging ,Cycling the air .
It doesn’t do it all the time.
I noticed it more when the AC is in service .
Any idea on why it is doing this ?
Thank you !!
Lol, you can't watch a TH-cam video and service equipment like a Tech with decades of experience and training. This weeks news had two elderly people die from there furnace running away and wouldn't shut off....
They had just had a family member "Service" there system to save money
Don't want to get ripped off? Build a relationship with a local company and use the same one every time
Having the burner going while removing/attaching the manometer tube and trying to quickly close/open the test port is a good way for someone to get killed, turn gas off and do such operation with the furnace inop. I just bought my buddy a new flame sensor, was around $25-30 my cost. Cleaning it with a wire brush is no bueno per manufacturers. You didn't talk about the drain trap in the video, probably the easiest model to remove trap/burners/blower on.
This is basically to make people intimidate the DIYer NOT TO CLEAN THEIR OWN FURNACE. !💔🤮
Telling people they don’t need a furnace serviced by a pro is pretty irresponsible! Not all HVAC companies are crooked! Every single furnace manufacturer requires they be properly serviced. Not just cleaning but checking it throughly for safety! Very very few homeowners have the proper tools or knowledge to do these things! And frankly you are showing them somethings that may get them hurt or worse! You only showed a portion of a proper servicing. Hope you have good liability insurance
I already commented on one of the videos, but will do it again.
Again, you are not " taking money from bad guys trying to rip you off "
Thus " repairs" by homeowner can create disaster.
People who follow these recommendations and
have no clue,can do more harm than profit to themselves.
Yes, many can remove burner and replace flame sensor per say, but how they are going to check if everything functional right? Manifold pressure is right?
Or maybe, there is dangerous condition caused by defective heat exchanger?
Trust me,I saw many guys keep reseting rollout switch with holes in heat exchanger. They red about it on internet, and this can be going very bad.
Please, use your common sense.
You can check your air filter or see if breaker tripped before calling tech.
Beyond that, leave to professional.
This isn’t stuff you should be showing the public. Too easy to make a mistake without noticing it. Also recommending someone to get 3 opinions for an issue is just throwing money away companies don’t do that for free. Also you tried to sell product throughout this video. Please use your brain and have some respect for your craft.
Would you ever consider doing the maintenance on a Lennox Pulse Furnace. I realize mine is older, but I continue to have excellent service from this furnace. (I always have a CO monitor near my furnace.) My current self maintenance includes oiling the blower and changing the air inlet flapper valve periodically. (And the filter of course…)
Thanks
This is a good video for a new service tech. Although I'm not a fan of checking gas pressure while the burners are lit right by the set screw. Homeowners.. don't touch anything. Change ur filter..clean ur flame senser if u want n check blower bearings and capacitor if u want but thats all I'd touch on this furnace. N service techs just blow out burner dust w CO2 tank. Removing manifold is more difficult with black iron gas pipe going into unit as opposed to flex pipe.
I never learned a detailed explanation on Furnance. Last winter in dec 2022 my furnace was not heating .The furnace was under repair contract. The contractor showed up and said pcb board is not working. It will take a week to get from manufacturer and ask the company sales person to advise on new furnance. The sales erson quoted for 5000 dollars . See how these companies traps their customers . I called a local person in Mississauga, Canada. He provided for $ 3000 a new six burners furnance and replaced next day. The ordered parts pcb came after 3 days only. The old furnce was tyrant 3 burned installed in 2004. The contractor name is Reliance . So this company is more efficient in selling product than doing maintenance and keeping spare parts
😆 had a HVAC guy come do a secondary inspection on my furnace after my home inspection on a home I sold. Of course he found my heat exchanger was cracked. I paid a different contractor to replace the unit. Once we got the old unit removed my HVAC contractor showed me where he scratched the heat exchanger with a screw driver to make it look like a crack. After closing on my house sale we found out the HVAC guy who did this was the uncle to the kid buying my house! They both worked for a very respected HVAC company in my area as well! HVAC guys are shady!
I WANT to have an expert come and fix my Rinnai, but no one will and the techs at Rinnai cant fix it. Im sticking with oil and gas boilers. They are stoopid simple and go forever. These new 98% efficient, computer controlled, direct fired units suck and cost way more since you got to replace them every 3 years or more.
Wondering about flue vent piping. Mine is rusty and I'd like to replace it. Is there flexible vent like for the dryer that you can use??
My coaches ceiling mounted heater randomly stopped working one morning. He called a guy to come check it out. Tech shows up, take a small panel off. Cleans some dust off a relay switch then turned it back on. It was just dusty around the switch. Heater has been working fine for 5 years now. That call cost cost him $275 for the tech just to show up and basically flick a switch.
Great teacher, excellent DIY video!! Knowledge learned, many many thanks !!!
Question with modern high efficiency furnaces is it necessary to call 2nd stage heating to ensure your inducer and blower motors and valve are at full title before checking current draw? I think you would need to jump W1, W1 and R?
Good luck in your next evolution. I will be watching. Got my Universal epa rating on skillcat (when it was free) thx to you. Have learned a lot from your videos- even installed a soft start on my a/c system to decrease inrush amps now that I added an EV charger on the same panel.
If it exists already please let me know , but I would love to see a video that explains the meanings of the wire lettering in thermostats and on the control boards.

15 yr old gas furnace.What should be done if the inducer, the big plastic thing is pulling double the amps? I do have lots of dust on the blower fan, and the blower motor is leaking oil and over amperage probably because of dust on blower. I also have leaks on the air exchanger.
First, Thank you for a well done educative video. I have a pretty new furnace, about 10 year old.
I always had the same company doing the maintenance, always requested the same technician, but the company ended up sending someone else to do the scheduled maintenance. Within a couple weeks I noticed the warm shower water goes from hot to cold while taking a shower, then a couple days later the heat was off when i checked the furnace there was a big water leak. My question is what caused that leak? Just to be preventive about it. I have propane, and the furnace is a New Yorker
That’s not true that it’s rare carbon monoxide comes out of the heater. I have proved and documented it multiple times with both residential and commercial equipment ultimately resulting in shutting the equipment down.
Carbon monoxide virtually never exits the “crack” it comes from the burners inlet ports. The pressure the blower puts into the heat exchanger reduces the draft in the heat exchanger prior to the crack. Generally long before the draft is reduced to the point of the flame rolling out the exhaust fumes (along with CO) will proceed the that flame. A lot of the time you’ll see discoloration / soot around the burner box area when this is happening even though you never actually see the flame touch those areas but soot from the fumes are still present.
Personally if you see anything that’s “odd” I’d call a professional. Call around to friends to find a company you trust. Then have the tech explain the oddity, if he can’t call someone else.
