You: find leak in the first place you look. Me: 3 days later customer finds my body laying on the roof with the H10 still beeping in my cold dead hand 😂😂
Maybe it's just dumb luck of checking around evaporator and condenser coil joints first? 🤷♂ I'm sure you could develop a statistically likelihood and check those areas in a certain order. (Not sure if anyone optimizes their work like that...)
@@fitybux4664 I have this thing when trying to find low voltage shorts on heat pumps where I almost always check defrost tstat/temp switch wires first and I have like a 65% success rate. Kinda similar to what you've described. For some reason it's highly likely for the defrost tstat wires to rub out on the suction line and blow the fuse. It I don't find anything there then I just go down my list of possible places and I'll usually find em fast.
I was a maintenance man at McD’s in my area when I was younger. Every year, we’d shut down the A/C units one by one & clean them out from top to bottom. If we discovered any problems, we had them fixed. Preventive maintenance absolutely goes a long way.
When I was younger same here climbing that ladder that led to a small roof opening the amount of lint that was pulled off of those machines was insane garbage bags full those were the days :)
“Excuse, the coke nose” 😂😂😂 I’m a tech and I really have learned a lot from you especially about being professional and don’t call a job finished just because the unit is running and cooling the job is finished until everything is fixed, we don’t have to get stressed just ask the customer if he approve the extra charge. Thank you
I’m about 4 months into schooling and just switched from a school bus driver to the maintenance department on the HVAC crew. I appreciate these videos and love your approach to each job that every inch of a unit maybe the problem. Your videos will help me become a great tech. I’m sure of it.
@@docholliday3218 I quit and got on with a large commercial company. I’m doing great and making lots of money. It’s all going well. Hard work pays off.
Good perspective on the maintenance and props for not shaming the lack thereof. You're absolutely right. In an ideal world, we would all maintenance everything on a schedule. In the real world, life is expensive and you pay for what you can and only when you have to lol.
Well they probably don't clean and take care of their vent hoods. A package unit should be getting that much grease through the air. Also ya they probably never changed those filters
1.) Your my hero 2.) I would have condemned that coil on the basis cleaner would have destroyed it. 3.) You now have personally sold ME on Viper cleaner..hot damn! Chris fantastic job. Hope YOU put the right filters in it!! Thanks for sharing
I'm tempted to get some of their cleaners as I maintain (end user, not HVAC tech) several mini-splits (and my house) that get nasty after 6-8 months running constantly. Local dealer won't sell me anything other then the spray foam cans of nu-calgon because I don't have WHMIS. Funny part is you can buy damn near any HVAC cleaner/brightner you want on Amazon, no WHMIS required.
Someone needs to make a "Roomba" for ducts! ;-) I wrote iRobot and told them we needed a "Roofba", and their legal dept. wrote me back and told me not to send any more "good ideas". The nerve.
You have the Winbot and many others for windows, so maybe you should contact any of the makers of those bots for a bot able to clean ducts? A video of the Winbot: th-cam.com/video/scqXKczd0tE/w-d-xo.html Or put it as a challenge for students at a university that are studying robotics.
The problem is if they make a roofba, you can potentially sue for them having stolen your idea. Or worse it wasn't your idea, it was your buddy's and you shared an idea that he was attempting to invent.
It's a matter of electromagnetism. The inside material of the ducts should have a neutral charge, so that dirt, dust debre, won't cling on to it. Then the indoor blower motor can move all of it into the intake side of the air filters. Same with PVC condensate drain lines. The problem can be solved with chemistry. The slime & gunk that builds up inside the PVC drain lines, has the opposite charge as the PVC material, do it doesn't just grow inside the PVC drains, but it also clings onto the material, making it difficult to flush out.... esp if it's hardened. Having a drain pipe material with a neutral charge would be greatly beneficial....bit this is HVAC/R so I wouldn't hold my breath! This trade seems to want to hold onto "Caveman" ways of doing things.
Me, an office guy in a country with very few AC units: ... TH-cam: here, watch a guy fix an AC unit! Me: watches whole video I gave you a thumbs up, fully aware that youtube is going to remember that until the end of days and I will spend the rest of my life watching AC repairs and probably some plumbing as well.
i started watching machinist videos, somewhere in the middle i saw plumbing/electrician channels, now i just accept the slippery slope of tradespeople videos
If he had burnt the crap out of his hand on the drier I don’t think it would be running that long. Personally yes I do have to use the back of my hands since it’s more sensitive but you most definitely can feel a temp drop. I’ve had plenty restricted driers that would ice solid bang right now yet I could still blow through no problem.
Not sure why this popped up in my recommended but out of boredom I watched and enjoyed it. Guess the youtube recommended was right for once. Always nice to learn something new. Never knew there were so many different skill sets required for ac/heating until repairs.
Great trouble shooting and repair! I used rubatex or foam tape to stop lines from vibrating! Like that rubber! Severe lack of PM! Pay me now or pay me alot more later! What I used to tell customers about pm! Thanks for another awesome video!
Absolutely love when new HVACR videos are released! They're so informative and after watching so many of these, I honestly feel like I could diagnose most basic/intermediate HVAC problems need that ever arrive, just from watching you work and explain! Super professional and super cool what you do. Keep up the great content!
Lately I’ve been using Zep citrus degreaser for really bad coils. I had some complaints about the smell of Triple D in a hospital. The Zep is $9 a gallon at Home Depot, smells nice and cuts right through the bugs and grease.
Hi from Australia! Don’t know why the algorithm sent me here about a year ago but I’ve subscribed because it’s just really relaxing swing things get repaired and cleaned!
This takes me back to when I was a maintenance tech for a large apartment complex. We had to have universal HVAC certification and every 3 years, or so, we'd have to clean the coils on the split system outdoor units. After 20-25 units cleaned, my face would be burning from the alkali based cleaner. This was 20+ years ago so I'm sure the newer stuff is better. I'll never forget the way it looked like cookies & cream ice cream coming out of the dirtier coils. Your videos are great, keep up the good work.
Its awesome that he says he's not perfect. I only do residential refrigerators but I still run in to things that just can't be perfect. Thanks for the content I learn something new every time I watch Excuse to Coke nose made me laugh we all have worked with them lol
Thank you for making these videos, I'm not in this business myself, but I find it very relaxing to watch these videos while working, I love electronics and cooling solutions.
Oh man! Talk about one thing leading to another... Evap coil clean turning into a leak search and repair. I hate those days on the field. Vibrations probably sourced from pulleys. Always gets me how unit vibration leads to more problems especially with tight piping abrasions. Outstand work of excellence!
Chris, as a 30-year Master HVACR tech, I have seen these types of leaks a lot on these commercial Lennox units. I always kept an old car or truck inner tube and after I blaze it all up I wrap a layer of the inner tube secured with zip ties, never had any issues after the repair. Just an old guy's tips, and use the same technique on filter dryers securing straps between the strap and dryer. Oh, and pressure control loops of cap line. My boss always wondered why I had 2-3 boxes of inner tubes and piles of zip ties lol I always made every unit look as good or better than the factory did when I left. lol I see you did a version of my trick, If I had just watched a bit farther in the video lol Sorry. :)
First time seeing one of your videos and type of work. I know nothing about HVAC, only a bit of electronic/electricity and how a AC works... At first looked like you will change some parts, filters, a cable or belt, wash a little and done. But as continue watching I saw tools I'll never knew, like bluetooth clamps, leak sensor and torching the pipes on the spot, even a little mirror. I admire your work, you really gained a lot of experience
The plastic will break way before the copper. It's not a big deal and if it means keeping the foam stuff on their tighter for longer it's absolutely worth it.
Had this for a machine shop every coil solid solidified oil. Used nubrite diluted like 8 to 1. Worked great took forever though get all the suds out and also get the smell out of coil.
I saw on a car grooming TH-cam channel and they use a bush attachment for a cordless drill brush with a soft bristles so it would work well for you . He also used a hand held steamer that worked a treat
Fantastic video! Very true to how it happens. I love Lennox products. I’m sure everyone is critiquing everything you’re doing. We’re all different and that’s the way it is. Great job! I wish I had ten of you on my crew! Thanks!
Good job!💯 When they are that bad I seal off the duct work and hit the coils with coil cleaner too! ACE makes a aerosol can coil cleaner spray that foams out everything as well, then just hose it off, works good...
HVACR VIDEOS was the HVAC subreddit. Was actually someone linked a video to the channel “Technology Connections” about personal air conditions. That channel linked your video on swamp coolers and I got lost on your channel from there lol.
Put me down for one of those high quality beanies. Tried to find them a week ago, so am quite glad to hear them mentioned again. Your customers have it pretty good, that was very satisfying seeing all that gross smoo getting turned loose like that.
THANK YOU FOR POSTING THIS!!! I have a Lennox unit just like this at a McDonald's I service. Nasty McGrease grease all over the evap coil, I was almost thinking new coil. Think I found a solution.
Dude. I am not an HVAC guy-I just enjoy watching techs in various disciplines to their thing-but your brazing skills are off the hook. What I learned today: How do you avoid flaring out a pinhole on copper tubing worn down to microns by contact vibration? You sneak up on it! 🤣
G --> Fan demand W1 --> Heating first stage W2 --> Heating second stage Y1 --> Cooling first stage Y2 --> Cooling second stage OCP --> Occupied signal R --> Transformer C --> Common wire
at 18:15 see if you can get asbestos fire blanket mats instead of towels we use them in the Telecom industry . No idea where they come from as company provides them . Similar to fire blankets . At 24: 00 dont you get legionnaires disease from lack of maintenance ?
I’ve run into a few of the leak repairs similar to the ones displayed. I’ve had good luck using 40 to 60% silver and flux. Also I’ve used Stay Brite and flux, especially on thin copper such as coils and return bends. Really good when you have The remote reading gauges and related would have been a godsend back in the day Good video
you should see some of them in residential, where nobody changed the filter since install in the 1980's lol. the self made carpeting filter is a mile thick, no airflow and they wonder why it doesn't heat or cool hardly :))
I find cleaning plugged coils extremely satisfying. The refrigeration system thanks you, you can just feel it ya know? Especially reach ins etc. on the cooks line jn restaurants. I’ve come across so many I could not believe we’re keeping temp with the amount of grease plugging the condenser.
Alternate title: Disaster Lennox Evaporator Extreme Cleaning and Detailing. Edit: Not sure if you end up catching it later in the video or not, but at 12:50 behind your duct detector and fire alarm system in that unit there were some wires rubbing out on that loose panel.
I think there were some wires above in front of the panel that were also rubbing out. Looks like there is lack of protection on the wiring and too much vibration.
Glad I'm not the only one that had that thought. I honest to God had a few seconds where I was wondering, "Why would anyone put insulation all over the coil like that?" Yikes.
LOL you always get me with the COKE nose. I get that too and now I know what to call it :D Edit: And another LOL at the end.. you are seeing who's making it all the way to the end of you video, very clever haha.
Hope the customer repairs the drain pan. Good find on the leak hard area to braze. Great to protect the lines from rubbing again. Nice days work. Can't wait for the hoodies and beanies. I need 2 of each thanks.
The cleaning of that unit no longer was a scheduled maintenance kind of thing. It actually turned into a service call by cleaning those coils you fix the unit probably 80% and then the repairs of the leak and the rest of the things you did is the hundred percent, it was actually a service call
Too bad doctors can't do that with patients. "And now let's just give his lungs a cleaning. Ahhhh. Now he can breath!" (Well, with routine exercise, I think your body kind of does this naturally...)
Nice job cleaning that nasty coil. It's telling ya I can breath now. LOL I have repaired leaks just as yours with the oxy/acetylene setup and the copper just disappeared, but the silver solder works nice for filling holes. lmao, Thanks for the video
That's one nasty evaporator seriously dirty, another great video as always , that blower motor is for sure about to die , stay safe out there. My bro, them filters are absolutely blocked to all hell too
The more blocked the evaporator, the less work the blower does. So cleaning the evap will make it work harder. Would have had a nice low load life for ages.
@@Thermoelectric7 fair point , i dont know that much about hvac im lookimg at doing it as an apprenticeship, chris from hvacr inspired me to do it , as hes a great tech , and thanks for explaining how it works man, tthat was helpful stay safe and if youve got any tips fire away buddy
yea lennox its common to check where suction lines run in top of units, they never do a great job to make sure it isnt too close to other lines, normally it rubs into liquid line.
22:29 So how do you get the outdoor coil entering air temp? Is that where you use a thermometer at the condenser coil where air is pulling through? I'm still new and trying to make sure I understand cause I second guess myself too much. Thanks for the great video by the way!
The rubber wrap will slow the damage, but the cause is the vibration/loose tube. A couple of cushioned suspension/line clamps could be used to secure that tube.
Wow 518 head!!!! Then I seen your OA 111 deg that’s crazy high head I’m in Houston we have wicked humidity and high 90’s all the time. I would say in August we will have a couple of weeks of low 100’’s I see you were running about 25-26 over ambient so wow yea 518 head Man that’s hot I feel your pain brother Great video big picture thanks a lot Really appreciate what you do

I love watching a good braze repair. On small thin tubing I like to use a map gas torch, makes it easier to not burn through the tube.

Wow! I never thought it would be that dirty! Great vid as always man!
That's what she ...
Sterling Archer lol

That cleaning was so satisfying😍
Hope the customer repairs the drain pan. Good find on the leak hard area to braze. Great to protect the lines from rubbing again. Nice days work. Can't wait for the hoodies and beanies. I need 2 of each thanks.
I love your work man .good job
WATCHED TO THE END BUT I DO NOT KNOW WHY AFTER DOING THIS WORK FOR 35 YEARS. IT MUST BE YOU MAGIC CHRIS.
The cleaning of that unit no longer was a scheduled maintenance kind of thing. It actually turned into a service call by cleaning those coils you fix the unit probably 80% and then the repairs of the leak and the rest of the things you did is the hundred percent, it was actually a service call
I love me a nice satisfying coil cleaning video. so relaxing...
Too bad doctors can't do that with patients. "And now let's just give his lungs a cleaning. Ahhhh. Now he can breath!"
(Well, with routine exercise, I think your body kind of does this naturally...)
Like the videos and the 4K quality
Great video dude please keep them coming? Stay safe
Nice I love watching cleanings
Nice job cleaning that nasty coil. It's telling ya I can breath now. LOL I have repaired leaks just as yours with the oxy/acetylene setup and the copper just disappeared, but the silver solder works nice for filling holes. lmao, Thanks for the video
Always a pleasure to see nice videos with great explanations 👍🏽
Same thing happened to my home HVAC.. Two copper lines touching, after vibrations it wore through.. Good ol R22 system but still running after fixing!
That's one nasty evaporator seriously dirty, another great video as always , that blower motor is for sure about to die , stay safe out there. My bro, them filters are absolutely blocked to all hell too
The more blocked the evaporator, the less work the blower does. So cleaning the evap will make it work harder. Would have had a nice low load life for ages.
@@Thermoelectric7 fair point , i dont know that much about hvac im lookimg at doing it as an apprenticeship, chris from hvacr inspired me to do it , as hes a great tech , and thanks for explaining how it works man, tthat was helpful stay safe and if youve got any tips fire away buddy
Great video Chris !
Great Job !! Love how that Evap turned out !
As always great content really enjoy your videos always learning something new. Keep it going Chris. Please
One of my commercial fridge had the same issue. Leaks due to 2 copper lines rubbing.
yea lennox its common to check where suction lines run in top of units, they never do a great job to make sure it isnt too close to other lines, normally it rubs into liquid line.
Another great vid! Thanks for making these videos, learn so much more on real world scenarios.
22:29 So how do you get the outdoor coil entering air temp? Is that where you use a thermometer at the condenser coil where air is pulling through? I'm still new and trying to make sure I understand cause I second guess myself too much. Thanks for the great video by the way!
Yes I measured the outside air entering the condenser
This foam dripping down would make an Alien special effects crew proud. Juk
The rubber wrap will slow the damage, but the cause is the vibration/loose tube. A couple of cushioned suspension/line clamps could be used to secure that tube.
Watching you clean that Evap coil was disturbingly satisfying for me
The last 30 seconds of the video, great stuff :)
3:50 What is an air conditioner economizer? I am more familiar with economizers in power plants.
Wow 518 head!!!! Then I seen your OA 111 deg that’s crazy high head
I’m in Houston we have wicked humidity and high 90’s all the time. I would say in August we will have a couple of weeks of low 100’’s
I see you were running about 25-26 over ambient so wow yea 518 head
Man that’s hot I feel your pain brother
Great video big picture thanks a lot
Really appreciate what you do
