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.

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!!

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.

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!

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.

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

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

I really appreciate you being opened to showing your knowledge on install thank you brother don’t worry about what none of these selfish men say

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.

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.

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

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 🙂

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

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.....

You are one of the best instructors, thank you very much for your teaching video.

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 !

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!

Dave, great video and your workmanship is absolutely A1!!! Keep up the great work!! Wish you were in my area!!

thank you good sir.!! not in the market to replace one but very good education.

Amazing professional working. Thank you

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!

Awesome video! Looking forward to the next one.

Thanks! I'll use this video to create a check list for the person who will replace my old furnace. Never know, they might forget a step or two 😂.

This guy is a great teacher

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!

Excellent video, thank you for sharing keep the good work!

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".

Great DIY video Dave. Yeah. I for one will have a professional change my furnace out.

Really Happy to learn from you man thank you!

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 💪

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. 👍

I put attention in all of your process and when you disconnect the Y1 you said w1. Hope not affect people to reconnect their wires. Good video

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 job, you were clear on the safety points and explained what you were doing and why.. Well done

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

Excellent ! Awesome workmanship!

To install AC and Furnace your self it's a dangerous job without school or without lisence because theses jobs supplies with gas and electricity, however everybody want to save money when Doing Right life is good but remember SAFETY FiRST. thanks for DiY video 😊

Great video! thank you for the efforts

Used Goodman and they are work horse that required very little maintenance. Very reasonable priced filters too. Carrier on the other hand....

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.

Nice install

Nice! I just bought a magicycle ocelot with similar specs for $1000 so i think that one is a great deal.

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.

This is a very useful video.

Thanks so much I really like you video. Thumps up all the way.

Great video with really thorough detail!!

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.

Thanks!

This was excellent

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!

You guided the coil box over the front edge of silicone with your left hand quality workmanship good seal.

Thanks Dave another good one.

Thanks for continuing to post these DIY videos! Keep them coming!

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!

Great content. This install was very straight forward. It’s nice to not do a lot of duct modifications on installs.

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 ...

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.

Very nice work

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 said thank you very much and appreciate it✨ please keep up the good work ✨I hope you make more video n I learn a lot from your video ✨

Thank you very much this video was very informative and helpful for me

Informative , I appreciate

Thanks for this detailed and informative video. Can’t wait for the next one!

Great video!

Thanks once again bro if a have to watch your videos a million time I will see then Thanks to these videos I become an expert you are the best

One of the best tutorials! I enjoyed watching it! Thank you for your work!

Great video, and great job!

Thank you

Man that's a nice install! I get it....your a journeymen so it should like a pro install. I hope mine don't look too ghetto!

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.

Good job David

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!

It would be nice to see a Goodman gas furnace review by one of your customers!

Great video, luv the use of the window screen roller, to add rigidity to the sheet metal. 👍👍

Very informative, thank you for the video. Question should the water heater also have a drip pipe?

I did not know that you can store all the freon in the condensing unit. Mind blown!😵

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

I'm impressed step by step instructions, very nicely done , you must have a great teacher

Thanks

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💥💥💥

Great channel. Love the fact that this HVAC person is not anti DIY. I am currently taking courses just so I can replace two of my systems.

Thank you for your videos. I decided to replace my evaporator myself instead of paying a tech $5,000.

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 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.

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.

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!

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!

Safety glasses and adjustable wrench works better other way round.

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

Great, you are the light in the dark

Can you please explain more on the static pressure test . Why and how

Sir you have no idea how much I have learned from you. Thank you.

I really like this KZfaq video.

goodman unit I bought had bad flame sensor. I replaced cheapest part two $5 no call backs slc

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

First, a huge thanks Dave for this video. I would like to see a public outcry against some of the misinformation from "professional" type heating or HVAC sites. You'd think they sit next to God. According to them, no one is competent to do their own work. Well, some of the worst work I've seen, including on gas, was from a pro. This channel and Dave are a godsend. And in my area, the arrogance of both installers AND supply houses is unbelievable when it comes to protection of equipment price information. If automobile repair shops and dealers tried this, they would get their asses handed to them. Most consumers are clueless about actual costs, installer discounts and finally, markups. I'm all in favor of a guy making money and staying in business but when he's pulling $500 per hour for a one or two day job, that's WAY too much.

You take static pressure in the blower portion and the heat exchanger, that’s your total static.

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.

I LOVE running a compressor to its death, little does it know this was (its) Last time running... my perfectionism side drove me to fix "it's"
