Thank you so much Dave for posting this video. So glad to see an HVAC tech like yourself that isn’t anti-DIY. I was never good at sheet metal work until I started watching your videos. Thank you again.
Go forward with the DIY installation and I guarantee you will regret it! Considering if you installed your new unit yourself it will now have no active warranties since a certified technician with an approved company didn't install it. I've only an HVAC Sales Expert for two years and even I know that! In his defense I deal with a lot more company to company and face to face interactions so maybe he just really didn't know.
AC Techs are anti DIY because of what the channel Anti DIY HVAC finds, all the time - people scammed by people who do installs of furnaces, poorly. Does that mean people's high prices are justified? Show me a rich AC tech first, then we'll talk.
You rock, Cleaned and replaced almost everything on 22 yr old furnace and upgraded the duct work and it works better than it did when it was new. Thanks for the info and the confidence inspired!
Let me just tell you as a far way friend you are the man and keep going.all the good honest people will support you regardless the haters that they will be affected by your videos because they can't scam and rip many people.
I moved furnace from crawl to closet and from 80% to 92%. 50% of duct work, line set, condenser and all. All for around $3,500. Appreciate your videos.
I've learned alot on this channel as a home owner and someone who has been working in the maintenance field for 15 years. Just do your disclaimer in all your video discriptions and let people decide if this is for them or if they want to hire a professional.
@@crand20033 Homeowners who have experience with DIY stuff can do just about everything except for the final steps that involve line flaring and dealing with the refrigerant. You can hire a professional for that final part of the project.
@davidnivison9915 I appreciate the DIY but i do not have the tools. I like your transparency and no BS, not the typical hyped extreme overpriced pro installation sales pitch. I want to hire you to install my furnace.
Nice install. It reminds me of my residential HVAC days. I'm strictly commercial HVAC now. Glad to see someone showing the proper way to install the equipment. Like how you made the duct fitting vs just throwing in a flex connector.
Great video! I have lots of respect for anyone who can do this. Even though I'd like to try it, I don't have enough confidence in doing the job correctly.
Awesome review, thanks Dave! At the end it looks like you checked the manifold, and flow pressures with a manometer. A short tutorial on that portion of an install would be really helpful. You did show the charts, but a lot of people probably wouldn't know how to use it properly. Thanks again for all the great tutorials! Happy New Year!
Channels like this are an invaluable resource for homeowners! Haters gonna hate. I see lots of HVAC guys checking a channel geared specifically to homeowners and being backseat drivers thinking they're rocket scientists. The fact of the matter is repairing and replacing HVAC systems if leaving it ALL to the "professionals" like SO MANY things has become cost prohibitive for a lot of people. Videos like this share info and can also lead people to NOT taking on such a job for themselves. It's a great research resource while determining if you (as an individual) have the mechanical ability and common sense to even consider doing it yourself. The Monday morning quarterbacks want to act as though safety is the ONLY concern which, it NEVER is! You can't change stupid and there would always be people biting off more than they can chew regardless of videos like this being there showing how simple a large part of a job like this is. $10-15k for a new system installed by "professionals"?! I can see people NOT replacing a system due to cost and dying of carbon monoxide poising. I think all homeowners should know more about maintenance, repair and replacement of essential home systems than most do. It's our right and responsibility! That's a great tip about pulling a permit and having it inspected as well! Haters gonna hate and who the F🖕CK cares?! Great video and channel! Thanks bro
So that's how it is done. My project house 55 year old furnace is needing to be replaced right now. Boy, the time is terrible because the freezing cold is just up ahead and I'm stressing. I was just curious how does the change looks like. Good video 👍
Hi Dave! 2 years ago installed my furnace. I did even a graph with natural gas pressure value to CO level in exhaust - to setup a proper gas pressure - my optimal pressure was 3.38 (instead of 3.5 recommended). This year I guess surplus Lennox SL18XP1 5 ton 15.5 seer AC to replace my old 20 yo 10 seer Goodman. I like your trick to retrieve R22 inside the unit.
Excellent presentation. Very helpful demo. I would hire you based on this. And I might even undertake the project, given that I have a reasonable hands-on background and most tools already. Keep up the great work. 👍
Thanks so much for taking the time to share your step by step install with us DIY guys , sooo much appreciated , so few professionals would do that. I have seen your a/c install videos but question if I should do that because of all the tooling i would need to buy along with the talent to use correctly. Offering assistance is over the top kind and so helpful !
At 7:00 and doing everything perfect, including what I always do is test the non-contact tester against a live wire to make sure it works instead of assuming it works. 53:59 if your supply plenum, return plenum and cabinet doesn't have a hole for a manometer, nobody has ever checked static pressure.
@@gordonroberts9339 Are you that bored that you need censor and challenge everything. The heat was working and my comment remains... Part 1.. well done
Another great video! I had a hvac system installed by Logan a/c & heating in Columbus, Ohio they didn't do anything what you have done. They did terrible work! They didn't seal nothing! All seams leaked air... etc.....
I didn't see any blue sealant on one of the sides of the gas elbow in the furnace. I will be using this video to help with my own install in my house. Thank you!
You sir, are the hero we need but don’t deserve. Love your content for us DIY’ers. Also, love all the HVAC guys hating on you 😂. Now they can’t price gouge everyone. Power to the people!
Awesome info for DIYer with a will to study the details. Thanks for covering this arena of harder to find specific. Like your style of Sharing Info. ...and Teaching. Thanks 🙂
I'm a DIY person and I hate paying for work. Just keep in mind most places won't sell you HVAC equipment. Goodman is about the only brand that you can buy online but here is their warranty policy: "No warranty coverage is offered on Goodman brand equipment purchased by consumers over the Internet, including web-based auctions, telephone or other electronic means, unless the unit is installed by a dealer adhering to all applicable federal, state, and local codes, policies, and licensing requirements".
It's similar to the american institute of architects who have high-sided many designers in a state like NJ. It's part of regulatory capture and bleeding people to death. All so dino's can keep sapping us.
Right on! If you need some help with your replacement, I offer one on one assistance for DIYers replacing their systems. That can be found at Patreon.com/diyhvacguy I also can help with getting the full 10 year warranty on your equipment. Cheers
Great video that shows so many steps and details! I found you through a podcast. I’ve had nothing but trouble with our Goodman units. They are only 4 years old. If I had the money I’d rip em out and replace them.
Hmm maybe poor installation? I’ve had pretty good success with Goodman but I might consider going with a different brand at some point. Thanks for the comment. Cheers

Very good video thank you very much for sharing as Wife and I if we win the place are getting a larger house for the growing family and the place has a 20+ year old furnace that I am sure needs to be replaced with a much more efficient model ... this will save us some big bucks as I am comfortable doing this sort of thing myself after reading up and learning the gotcha's ...
Every time I get another house or move, the 1st thing I do is change the switch to an outlet and put a plug in on the furnace. I know you're not supposed to but when you live in areas that can get -50c why would you risk having no heat in a power outage. This way I can run my generator and power up the furnace in an emergency. Seems like this should be a standard installation in very cold climates.
The old unit you took out did not look bad. The A coil looked pretty good yet What was wrong with it that it needed replacement? Good clear explanations of what was being done and why
Bingo!!! He only took out the UNIT & not the SYSTEM a play on words!!! Too bad he could not replace the SYSTEM that would be exceptual. Just pointing out. The UNIT is way different than the SYSTEM.

instead of a flat piece of piece of sheet metal to reduce the filter rack opening, possibly the flat piece with a ~1 inch flange bent up 90 degrees for screw attachment to cold air return? Good demonstration.
I’ve done my own entire system including ductwork in 4 houses now. I did the load calcs. and ductwork design and all the installation except I hired a neighbor that has a refrigeration and air conditioning business to braze the line set, evacuate the system and start up the AC. The reality is that in most of the country nowadays the average hvac tech probably doesn’t know what manual J or manual D are much less how to do the calculations. Most ductwork is done at the third grade level with zero actual design and systems are spec’d out using outdated and inaccurate old rule of thumb nonsense with no consideration for the actual characteristics of the house resulting in systems that don’t function properly. I can confidently say that all of the systems I did myself are better than I would have gotten had I hired it out. I’m in my retirement house now, it was a spec house we bought new when we moved to Tennessee 6 years ago and I have redone most of the ductwork in this house. If hvac guys don’t want people doing their own work then they should do a better job and train their new guys better. I’m a retired electrician and one of my favorite things in the electrical code is where it says all work must be done in a neat and Workman like manner, I think every code should have that language.
I bought an old house has a basement furnace. I haven't used it yet because the summer, but A thermostat on a home furnace; is that supposed to go to 5,000 degrees, you think? This one does

Respect, working on the gas line as a layman can be very dangerous, boom, boom and the house is gone. Best regards from a German heating, gas and water installer💥💥💥
Greatly appreciate the overview. I can understand why trade professionals get agitated but reality is there are some who are more than competent to do an install like this. I also think it is good for those who are comfortable to better understand how their homes operate and maintain them. Just my thoughts and to let you know you're content is appreciated.
I've learned a lot from you about aspects of this work. But I have another concern about the over-tightening of steel pipe and fittings. This pipe is threaded on a taper. Over-tightening steel pipe into brass fittings could split the fitting. Thank you, sir, for sharing your knowledge. Regards.
Cutting sheet metal without gloves! LOL :-) Excellent video! I will change my 85% Efficient with another 85% Efficient because I need to get rid of the pilot light that keeps blowing away with high wind storms. Would you recommend an upgrade to get rid of the pilot light without replacing the entire furnace? I like the Furnace Igniter upgrade if it exists.
Love ALL your videos Dave! Only problem is that I can't find a supply house who will sell to someone w/o a pro HVAC contractor account that's not established!
My furnace is from 1980s. Replaced blower about 10 yrs ago and a thermistor a few years ago. It's on borrowed time. I want to replace myself but part I'm not sure about is the sheet metal work

Don't know bout those lever locks. Hard to teach a hard headed old dog a new trick. But to support you, I may buy a small box just so I can say I tried them!
Thanks for sharing your tips and knowledge on DIY install. I will look for a professional to do brazing and pressure testing and to sign off on the install for warranty reasons. My question is on sizing. I have a 20 year old home that has the original 3 ton AC / 100000 btu gas furnace in Minnesota. The system runs almost continuously on the coldest and hottest days but has always been able to maintain set temps. Most charts on sizing say I should have a 4 ton system. Should I upgrade the size of my system? Also, do you recommend a 1 or 2 speed system? I’m seeing lots comments here by professionals talking about the expensive tools and involved techniques for tuning. I worked with the professional on the install on my last home and the only specialized tools he used were the pressure gauges for checking pressures and the torch for brazing lines. That system has been running flawlessly for 10 years.
I researched gas furnaces for DIY installation in early 1990's. I purchased one of the Goodman line of gas furnaces for lower cost initial purchase and future parts availability and lower cost parts. I note your choice of Goodman these days. DIY these days = financial self defense from the unscrupulous when an honest trades person/contractor is not to be found.
Dave: around the @10:50 mark you misspeak on the terminal designations and color codes. I’m sure it was just an error from being distracted by the camera, but at the very least you should put a correction on the screen during that part. W1 is not a call for cool. Y1 is a call for first stage cool. W1 is a call for first stage heat. And G from your thermostat to your furnace will bring on the furnace blower during a cool call. G call on heat isn’t necessary on a furnace because the furnace board controls the blower relay as part of the order of operations for safety reasons.
Flexible gas connectors are for movable appliances only, such as clothes dryer, stove, oven. Furnaces and water heaters are not movable appliances. The vertical gas drops and not supported and are swinging by the flex connector.
No flex line to furnace or water heaters in Michigan must be black hard pipe … I also have my HVAC guys mastic inside seams so no air leaks also tape outside seams on return, coil and takeoffs
I love your channel and watch your videos. I do not recommend Goodman furnace products. I purchased three of them and the cheap circuit boards went out and caused all kinds of expenses for years. One went out on a tenant on Christmas Eve. Bryant has been way more reliable.
Hi, I have a question: my heater is in the basement. It has two outlets: one duct that outputs hot air to all the rooms and another duct that outputs only to my living room, normal air. How does it work or what is it for?
HVAC guys typically seem to think they are far above average intelligence. However I watch teenage pot heads install HVAC in New homes everyday as the boss sells jobs price gouging because even the supply houses won't tell you the cost of materials. HVAC guys have a terrible reputation And they have earned it and most deserve it glad to see a helpful HVAC guy!
Thank you for installing the drip leg on the gas line properly. You should maybe explain the drip legs function and common mistakes that are often made even by professionals in how they are installed . I have seen union "proffesionals" screw this stuff up on many jobs regarding drip legs because of a drawing in the factory installation guide / manual was drawn wrong by an idiot. Thanks also for showing that gas pipes don't need to be tightened until you can't turn them any more. I have seen this many times before and actually found this stupid crap actually cracked a few fittings and caused leaks.
Thanks very much for making this video. The return air duct is connected to the bottom of my furnace that I want to replace. How will the installation be different?
You just don’t cut the side of the furnace, and then you remove the sheet metal that comes screwed to the bottom of the furnace! It will be easier for you then the side return like shown in this video 👍🏼
Thank you so much Dave for posting this video. So glad to see an HVAC tech like yourself that isn’t anti-DIY. I was never good at sheet metal work until I started watching your videos. Thank you again.
Happy to help. Thanks for the support! Cheers

The reality is that in most of the country nowadays the average hvac tech probably doesn’t know what manual J or manual D are much less how to do the calculations. Most ductwork is done at the third grade level with zero actual design and systems are spec’d out using outdated and inaccurate old rule of thumb nonsense with no consideration for the actual characteristics of the house resulting in systems that don’t function properly. I can confidently say that all of the systems I did myself are better than I would have gotten had I hired it out. I’m in my retirement house now, it was a spec house we bought new when we moved to Tennessee 6 years ago and I have redone most of the ductwork in this house. If hvac guys don’t want people doing their own work then they should do a better job and train their new guys better. I’m a retired electrician and one of my favorite things in the electrical code is where it says all work must be done in a neat and Workman like manner, I think every code should have that language.
Wow, sure looks new. I'm still using a 1982 Lenox
I bought an old house has a basement furnace. I haven't used it yet because the summer, but A thermostat on a home furnace; is that supposed to go to 5,000 degrees, you think? This one does
Very nice work
Awesome job and awesome vid! Thank you fir this series sir! I appreciate the information sooo much! Can't wait to watch the other two vids in series. More and more, you instill confidence me bud! Keep them coming. BTW....my compliments to your camera man...er woman. Yall are a great team!
Thanks :) it’s been nice having a helper to film and have some fun with 👍🏼
@@Kevin-mp5of No comment on the original poster's spelling and grammar? Do you only do that to folks you disagree with to try and come off as superior? Shameless double standard....
Came for the hate comments. Don't disappoint! Nothing less than a full on linguistic thrashing will do, now get on it! 😃
God forbid somebody learns how to save themselves some money with these solid videos.
@@gordonroberts9339 😂😂😂😂😂Knew it wouldn't take long for the purse swinging to start. You best not pump gasoline into a vehicle in the winter since you build up a static charge. Better if you ride a bike or walk. 😃
@@strykerentllc are you a homeowner or in the hvac field?
@@charliec259 Fry cook at the Krusty Krab if it makes any difference to you, bruh. Knowing HVAC and electrical code and complying with them isn't launching satellites into orbit. 😎
This is a very useful video.
Respect, working on the gas line as a layman can be very dangerous, boom, boom and the house is gone. Best regards from a German heating, gas and water installer💥💥💥
Greatly appreciate the overview. I can understand why trade professionals get agitated but reality is there are some who are more than competent to do an install like this. I also think it is good for those who are comfortable to better understand how their homes operate and maintain them. Just my thoughts and to let you know you're content is appreciated.
I've learned a lot from you about aspects of this work. But I have another concern about the over-tightening of steel pipe and fittings. This pipe is threaded on a taper. Over-tightening steel pipe into brass fittings could split the fitting. Thank you, sir, for sharing your knowledge. Regards.
Cutting sheet metal without gloves! LOL :-) Excellent video! I will change my 85% Efficient with another 85% Efficient because I need to get rid of the pilot light that keeps blowing away with high wind storms. Would you recommend an upgrade to get rid of the pilot light without replacing the entire furnace? I like the Furnace Igniter upgrade if it exists.
Love ALL your videos Dave! Only problem is that I can't find a supply house who will sell to someone w/o a pro HVAC contractor account that's not established!
My furnace is from 1980s. Replaced blower about 10 yrs ago and a thermistor a few years ago. It's on borrowed time. I want to replace myself but part I'm not sure about is the sheet metal work

Don't know bout those lever locks. Hard to teach a hard headed old dog a new trick. But to support you, I may buy a small box just so I can say I tried them!
Right on. You will love them!!
Thanks for sharing your tips and knowledge on DIY install. I will look for a professional to do brazing and pressure testing and to sign off on the install for warranty reasons. My question is on sizing. I have a 20 year old home that has the original 3 ton AC / 100000 btu gas furnace in Minnesota. The system runs almost continuously on the coldest and hottest days but has always been able to maintain set temps. Most charts on sizing say I should have a 4 ton system. Should I upgrade the size of my system? Also, do you recommend a 1 or 2 speed system? I’m seeing lots comments here by professionals talking about the expensive tools and involved techniques for tuning. I worked with the professional on the install on my last home and the only specialized tools he used were the pressure gauges for checking pressures and the torch for brazing lines. That system has been running flawlessly for 10 years.
This was excellent
What gauge of sheet metal do you use for the plenum?
I researched gas furnaces for DIY installation in early 1990's. I purchased one of the Goodman line of gas furnaces for lower cost initial purchase and future parts availability and lower cost parts. I note your choice of Goodman these days.
DIY these days = financial self defense from the unscrupulous when an honest trades person/contractor is not to be found.
Don't depend on just a gas shut off. Always cap the dead end of a gas line. Even if there is a shutoff
Sir you have no idea how much I have learned from you. Thank you.
Awesome glad you are benifiting from them 👊🏼
Dave: around the @10:50 mark you misspeak on the terminal designations and color codes. I’m sure it was just an error from being distracted by the camera, but at the very least you should put a correction on the screen during that part.
W1 is not a call for cool. Y1 is a call for first stage cool. W1 is a call for first stage heat. And G from your thermostat to your furnace will bring on the furnace blower during a cool call. G call on heat isn’t necessary on a furnace because the furnace board controls the blower relay as part of the order of operations for safety reasons.
Great video with really thorough detail!!
Glad you enjoyed it!
Thanks Dave another good one.
Of course. Thanks for watching!
Informative , I appreciate
Flexible gas connectors are for movable appliances only, such as clothes dryer, stove, oven. Furnaces and water heaters are not movable appliances. The vertical gas drops and not supported and are swinging by the flex connector.
Great video!
Can you please explain more on the static pressure test . Why and how
No flex line to furnace or water heaters in Michigan must be black hard pipe … I also have my HVAC guys mastic inside seams so no air leaks also tape outside seams on return, coil and takeoffs
I love your channel and watch your videos. I do not recommend Goodman furnace products. I purchased three of them and the cheap circuit boards went out and caused all kinds of expenses for years. One went out on a tenant on Christmas Eve. Bryant has been way more reliable.
Hi, I have a question: my heater is in the basement. It has two outlets: one duct that outputs hot air to all the rooms and another duct that outputs only to my living room, normal air. How does it work or what is it for?
HVAC guys typically seem to think they are far above average intelligence.
However I watch teenage pot heads install HVAC in New homes everyday as the boss sells jobs price gouging because even the supply houses won't tell you the cost of materials. HVAC guys have a terrible reputation And they have earned it and most deserve it
glad to see a helpful HVAC guy!
Thank you for installing the drip leg on the gas line properly. You should maybe explain the drip legs function and common mistakes that are often made even by professionals in how they are installed . I have seen union "proffesionals" screw this stuff up on many jobs regarding drip legs because of a drawing in the factory installation guide / manual was drawn wrong by an idiot. Thanks also for showing that gas pipes don't need to be tightened until you can't turn them any more. I have seen this many times before and actually found this stupid crap actually cracked a few fittings and caused leaks.
Thanks very much for making this video. The return air duct is connected to the bottom of my furnace that I want to replace. How will the installation be different?
You just don’t cut the side of the furnace, and then you remove the sheet metal that comes screwed to the bottom of the furnace! It will be easier for you then the side return like shown in this video 👍🏼
@@diyhvacguy I see. That makes sense. Can I also use the air filter rack in that case? Would the rack be able to hold the weight of the furnace?
Great video, and great job!
Thanks! 🙏🏻
Hey man great install only thing I would do differently is put a trap on the gas line but otherwise great job bro
Oh nevermind I didn't see the trap my fault 🤣🤣
Haha no worries. Thanks man
