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.

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.

Installed my own furnace, and found it to be surprisingly easy. The exhaust vent to the chimney was the hardest part. You can do it!!

[jimreitenbach]

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.

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.

wanted to say I and appreciate you and people like you because you have save me a lot of money. Thanks.

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.

Window spline tool to brake the sheet metal nice. Heads up that sheet metal is sharp be extra careful when working with it.

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

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.

[alexgg]

I did install for 2 years great video remembering the job the bad thing was those tightly crawl spaces hated it those installs

[calmannomore]

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".

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...

[scottmcdonald]

What a great tutorial video. Keep up the great work. Very thorough. Good clean install. I look forward to watching each of your videos.

[thebluelunarmonkey]

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.

[coriding]

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!

[mikea.]

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.

[stephenphale]

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!
