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.

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
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.
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.
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!
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.
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.
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.
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.
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. 👍
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 ...
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!
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.
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 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
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.
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 !
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💥💥💥
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.

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 👍🏼
@@gordonroberts9339 Are you that bored that you need censor and challenge everything. The heat was working and my comment remains... Part 1.. well done
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

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.
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!

If the fan motor doesn't work, and I assume compressor still works, will you be able to press the contactor and get the coolant on the one side still? or do you need a fully working AC to do this?
I have had my 3 ton replaced with a Goodman many years ago. I was expecting the A coil to be nasty but it was fine. My question is if I do a diy next time is it absolutely necessary to change the A coil. It requires cutting into the duct work .it vertical above the furnace.however it has been cut into last time closed up and sealed with metal tape
There would be absolutely no reason to need to change your evaporator unless it was leaking but also you would need to find and indoor blower and furnace setup that are compatible with your old evaporator. It honestly would make that whole process more complicated But 100% if you are planning on going bigger like a 5 ton unit for example you absolutely need to change that evaporator it will not keep up. And to be honest with you it would be much easier for a DIYer to just buy matching and compatible everything.
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.
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.
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?
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.
Merry Christmas dave, HI! how are you doing. I whach you clip all the time, your do awesome show and explains very well and clearly, I love what you do. You are do great works 💪
They say it’s about a 15% decrease in your electric and gas, so it kind of just depends on if it’s worth it for you as a homeowner. Depending on how much of a price jump to high efficiency. Maybe I’ll do a video on this soon. cheers, Dave

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.
Thank you for this video, my furnace is 22 years old. It works fine, but the air duct input is made not on the side, but at the back of it, and as a result, the air filter must be removed in the summer otherwise the air conditioner coil will be frozen and the filter itself in the winter is always clogged at the bottom, so I have to rotate it by 180 degrees after 3 month or so in the winter. Eventually, I want to get the same mid-efficiency furnace and connect it to the same liner I have installed. What was the reason you removed that old furnace - did it fail? Are these mid-efficient furnaces still available nowadays? Where can I get one? Also, can you comment on what you measured with that HT-1890 manometer and what you adjusted?
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!
I’ve seen firsthand what home ownership can do with items DIY projects as for furnace installation!! And what I seen was an installation that would Kill the whole family in the first hour of operation
@@redraiderrider3289 It might seem ridiculous to you but it does happen. I got called out to a house once where the homeowner claimed his furnace had just stopped working. What I saw when I got there was a furnace and coil that was connected to the supply duct work but not the return, a flue pipe that went 15' across the basement ceiling and stopped, and low voltage wires not connected. This was clearly a half finished diy install, and it quite literally could have killed everyone in the house if it had ever attempted to run due to exhaust gasses expelling into the basement then getting pulled in through the wide open return, distributing those gasses through the home. Obviously this is not an everyday situation, but it does happen.
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
I installed the exact goodman you did and I had a black wire just laying the bottom of the furnace and it had a connector on one end and just copper on the other and it's about 12 inchesong do you know what this wire is for
Thinking of doing this myself since my furnace is 20 years old. Ebay sells them. Just choosing the right time of year before it fails when you NEED IT. 😬 Already did my gas water heater a few years ago.
Don't let the greasy filthy HVAC thieves get you. You won already I see. These guys think their filthy racket can continue. Homeowners are wising up to the game!
If my old air conditioner and coil are r22 refrigerant, and I am installing a new one and is r410a refrigerant do I need to replace the copper pipes from the condenser to the coil ?
No, just a flush and you will good to go! Watch this video and I show the easiest most cost effective method 👍🏼 ua-cam.com/video/Sxx4pNBF0_0/v-deo.html
What is the white sealant, and where can I get it? Plus I thought the drip line was in case there is water from condensation in the gas supply line. Thanks
Hi Dave, I like all your videos. I'm struggling with my furnace. Do you have any idea why the heater doesn't stop even when I turn off the thermostat? It keeps working until it melts the furnace wires. I've already changed the high limit switch and the control board also the thermostat,i hope you respond me. Thanks
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
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.
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!
Dave, I have grown to trust you quite a bit. I have a question: I had an HVAC guy come out and he said the AC fan unit looks good, but the capacitor isnt operating at ideal levels. He said he could replace it for $300+. I told him id have to think on it. Is this something I could easily do myself? I am an automobile mechanic and a handy man
Yes, Save your money. I can’t walk you through how to do it. Or just follow one of my videos on how to replace a capacitor 👍🏼 you can get a new one for 15 bucks
Awesome video and helpful! Is you live in Texas, would you recommend replacing a gas furnace with a electric? What is good/bad in replacement gas with electric? Do you have a video what shows how this is done?
Great video Dave, thank you! You installed a Goodman unit, do you feel they are of decent quality, or are any others better? The reason I ask, is that in our community in NE Florida, the builder installed Goodman heat pumps, and most homeowners are having issues with them, mostly corroding coils, and not high quality components. Thanks!
I have 36 years in the trade, and I can say with certainty, that most of the components in unitary systems are the same regardless of brand. In an apple to apple comparison, no manufacturer is better than the other, since they all share many 3rd party component. Now on to coastal, I have done HVAC in 5 states but the only coastal work was in southern California, and yeah salt water air and condensers don't mix well. I saw no difference in performance between brands, nor units stated as coastal rated. Ive never been a geothermal fan in general, here in the midwest I can do Mitsubishi and are Bosch heat pumps at close enough to COP for a lot less money that I don't see geo be advantageous, but coastal the initial cost may make sense of replacement costs of air to air heap pumps dying from salt water air.

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 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
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.
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 !
🙏🏻 Of course. Thanks for the support!
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💥💥💥
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.
Thank you for your videos. I decided to replace my evaporator myself instead of paying a tech $5,000.

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?
Nice job, you were clear on the safety points and explained what you were doing and why.. Well done
🙏🏻
@@gordonroberts9339 Are you that bored that you need censor and challenge everything. The heat was working and my comment remains... Part 1.. well done
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

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.
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!
Thanks for this video!! I just got a estimate for $18,000! I don't have that kind of money. So I'm going to do it myself. Very helpful video! Subbed!
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
If the fan motor doesn't work, and I assume compressor still works, will you be able to press the contactor and get the coolant on the one side still? or do you need a fully working AC to do this?
You can do it without the fan. It only takes about 2 minutes to pull the refrigerant into the condenser
Cuestion is the furnace gas valv it have to be adjusted. On new installation or dependent on the furnace. I just do one ??
Amazing professional working. Thank you
I have had my 3 ton replaced with a Goodman many years ago. I was expecting the A coil to be nasty but it was fine. My question is if I do a diy next time is it absolutely necessary to change the A coil. It requires cutting into the duct work .it vertical above the furnace.however it has been cut into last time closed up and sealed with metal tape
There would be absolutely no reason to need to change your evaporator unless it was leaking but also you would need to find and indoor blower and furnace setup that are compatible with your old evaporator. It honestly would make that whole process more complicated But 100% if you are planning on going bigger like a 5 ton unit for example you absolutely need to change that evaporator it will not keep up. And to be honest with you it would be much easier for a DIYer to just buy matching and compatible everything.
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.
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.
What gauge of sheet metal do you use for the plenum?
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?
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.
Can you please explain more on the static pressure test . Why and how
Merry Christmas dave, HI! how are you doing. I whach you clip all the time, your do awesome show and explains very well and clearly, I love what you do. You are do great works 💪
🙏🏻
I'm glad I found your channel. Good instruction. Is it worth getting a 96% efficiency rather than a 90% or so furnace?
They say it’s about a 15% decrease in your electric and gas, so it kind of just depends on if it’s worth it for you as a homeowner. Depending on how much of a price jump to high efficiency. Maybe I’ll do a video on this soon. cheers, Dave
Nope. As a 20 year HVAC-R tech I repair/replace way more 96ers than 90s. The 90s that I work on are old.
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. 😎
I did not know that you can store all the freon in the condensing unit. Mind blown!😵

@@diyhvacguy ok thank you
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.
Thank you for this video, my furnace is 22 years old. It works fine, but the air duct input is made not on the side, but at the back of it, and as a result, the air filter must be removed in the summer otherwise the air conditioner coil will be frozen and the filter itself in the winter is always clogged at the bottom, so I have to rotate it by 180 degrees after 3 month or so in the winter. Eventually, I want to get the same mid-efficiency furnace and connect it to the same liner I have installed. What was the reason you removed that old furnace - did it fail? Are these mid-efficient furnaces still available nowadays? Where can I get one? Also, can you comment on what you measured with that HT-1890 manometer and what you adjusted?
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!
I’ve seen firsthand what home ownership can do with items DIY projects as for furnace installation!! And what I seen was an installation that would
Kill the whole family in the first hour of operation
Lol. OK bud.
@@redraiderrider3289 It might seem ridiculous to you but it does happen. I got called out to a house once where the homeowner claimed his furnace had just stopped working. What I saw when I got there was a furnace and coil that was connected to the supply duct work but not the return, a flue pipe that went 15' across the basement ceiling and stopped, and low voltage wires not connected. This was clearly a half finished diy install, and it quite literally could have killed everyone in the house if it had ever attempted to run due to exhaust gasses expelling into the basement then getting pulled in through the wide open return, distributing those gasses through the home. Obviously this is not an everyday situation, but it does happen.
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
DIY guy installed it probably
Where do you buy the new furnace and what's the most reliable furnace (consumer report) for year 2023? Thanks!
I installed the exact goodman you did and I had a black wire just laying the bottom of the furnace and it had a connector on one end and just copper on the other and it's about 12 inchesong do you know what this wire is for
Probably on one end of the door switch!
@@diyhvacguy thank you I will check that
Thinking of doing this myself since my furnace is 20 years old. Ebay sells them. Just choosing the right time of year before it fails when you NEED IT. 😬 Already did my gas water heater a few years ago.
Well, my main board failed this week. HSI failure. Bad relay. Amazon and $130 I'm still going! 😁
Don't let the greasy filthy HVAC thieves get you. You won already I see. These guys think their filthy racket can continue. Homeowners are wising up to the game!
If my old air conditioner and coil are r22 refrigerant, and I am installing a new one and is r410a refrigerant do I need to replace the copper pipes from the condenser to the coil ?
No, just a flush and you will good to go! Watch this video and I show the easiest most cost effective method 👍🏼
ua-cam.com/video/Sxx4pNBF0_0/v-deo.html
What is the white sealant, and where can I get it? Plus I thought the drip line was in case there is water from condensation in the gas supply line. Thanks
Great video. Where can I purchase the furnace? And what specs do I need when ordering it
Hi Dave, I like all your videos. I'm struggling with my furnace. Do you have any idea why the heater doesn't stop even when I turn off the thermostat? It keeps working until it melts the furnace wires. I've already changed the high limit switch and the control board also the thermostat,i hope you respond me. 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
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
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.
Excellent ! Awesome workmanship!
Thank you so much!
Great job too . I learn lot from you.
Hi Dave Do You need license to install the furnace gas??? And meter to adjust gas and check gas too right??thank you and have a wonderful day,
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!!
Is it necessary for the exhaust to be three inch pvc pipe or is 2 inch good enough?
Awesome video! Looking forward to the next one.
That core filled with nitrogen, so is that for just AC? Is that removed and not used if my house just has heating? The AC we use a swamp cooler.
Really Happy to learn from you man thank you!
Dave, I have grown to trust you quite a bit. I have a question: I had an HVAC guy come out and he said the AC fan unit looks good, but the capacitor isnt operating at ideal levels. He said he could replace it for $300+. I told him id have to think on it. Is this something I could easily do myself? I am an automobile mechanic and a handy man
Yes, Save your money. I can’t walk you through how to do it. Or just follow one of my videos on how to replace a capacitor 👍🏼 you can get a new one for 15 bucks
@@diyhvacguy Recommend one please. The one in there is a Motor Run Capacitor TRCFD455
Nice install
thanks for this very educational video, if people diecide to DIY, where is the best place to buy furnace or parts ? thanks
Amazon , hvacdirect.com , and acwholesalers are great sources.
Awesome video and helpful!
Is you live in Texas, would you recommend replacing a gas furnace with a electric? What is good/bad in replacement gas with electric? Do you have a video what shows how this is done?
Great video Dave, thank you! You installed a Goodman unit, do you feel they are of decent quality, or are any others better? The reason I ask, is that in our community in NE Florida, the builder installed Goodman heat pumps, and most homeowners are having issues with them, mostly corroding coils, and not high quality components. Thanks!
I have 36 years in the trade, and I can say with certainty, that most of the components in unitary systems are the same regardless of brand. In an apple to apple comparison, no manufacturer is better than the other, since they all share many 3rd party component.
Now on to coastal, I have done HVAC in 5 states but the only coastal work was in southern California, and yeah salt water air and condensers don't mix well. I saw no difference in performance between brands, nor units stated as coastal rated.
Ive never been a geothermal fan in general, here in the midwest I can do Mitsubishi and are Bosch heat pumps at close enough to COP for a lot less money that I don't see geo be advantageous, but coastal the initial cost may make sense of replacement costs of air to air heap pumps dying from salt water air.
