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!!

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.

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.

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!

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.

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.

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".

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!

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

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!

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

You’re the best when it comes to hvac

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.

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.

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.

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

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 !

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

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

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

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

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.....

This guy is a great teacher

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.

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

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

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 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.

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!

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

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.

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.

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 😊

Kudos to the DIY people if you follow this man’s instructions but remember your home owners insurance probably isn’t going to cover unlicensed work even done by the owner. To the people that claim every hvac company is ripping people off I’d highly recommend a business class or talking to someone who owns a company. Most barely see any of the “ripped off” money you guys are crying about because of how much overhead they have. Most probably don’t even know of the seer rating changes that makes it even harder since now in a lot of states you can’t sell anything less than 16 seer units. So be more mad at your government.

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 😂.

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

Yes good advise! In 1994 got a $5500 bid to install a $1700 Ruud gas hot air furnace. Easy math on savings. Did the install myself -- vent, gas, plenum. Took 2 days, included getting furnace; not a bad hourly rate ($3800/24 hours). Running fine to this day. Furnace install manuals are well written, but with some HVAC lingo...

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

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.

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'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.

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

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. 👍

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.

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.

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!

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

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

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 ...

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

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

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.

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.

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.

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

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!

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 💪

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

Don’t do that, that’s why Goodman gets a bad name. People who shouldn’t be installing equipment are trying to install equipment. Reclaim your refrigerant so it isn’t accidentally vented later.

great job explaining things. one thing I would do before proceeding is do a leak check on those two new connections at the beginning. not everyone can smell the gas, like me (thanks covid). It's sad how so many poeple underestimate themselves when it comes to DIYing things like this. Sadly, there are some sales warehouses that refuse to sell units or parts to people that don't have a license to install them. I had some guy at home despot tell me that I was required by law to hire a plumber to change my water heater and refused to sell me a water heater in Tennessee. I have not been to home despot since, only go to lowes if i go to big box stores.

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.

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!

The guy I worked for always used the gas-rated yellow Teflon tape for gas pipes. We saw one case where a new gas valve failed because the excess pipe dope squeezed out inside the pipes fouled the screen on the intake side. That's not criticism of you necessarily, I'm just telling what I've seen. Good job adding the bushing. I'm going to assume the pre-made BX cable has the required red hat inside. That only leaves the ground in the handy box that holds the switch. All junction boxes and other metal enclosures must be mechanically bonded to ground with a green grounding screw. The painted surface of the furnace and even conduit and BX are not robust enough to ensure good grounding. I thought of a way to look at it that may help you see. Periodically in the past, people have been electrocuted and the investigation found the fault to be unprotected wires that have worn through because of sharp edges and vibrations or whatever. It may take decades for the damage to happen but happen it does and the consequences can be very grave indeed. So the code errors on the side of caution and requires bushings everywhere every time no matter how improbable the chance. Bonded grounds too. If a wire comes loose and touches a metal enclosure that is properly bonded to ground then the breaker trips because if it doesn't the enclosure will be hot. Possibly this will go undetected until one day when someone servicing the unit for some completely unrelated issue goes to turn it off. I suggest you add green grounding screws to your kit along with the screws that have the short pigtail attached to make jumping through the hole easier. And the red hats for when you encounter old BX then need 'em. And a supply of the new style handy boxes with the raised and threaded hole for the ground screw to just swap out those old ones that do not have the hole nor threads and certainly not space at the back for the ground screw to poke through. It's just quicker to use a new style handy box than making the old ones work.

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

Amazing professional working. Thank you

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

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

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

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.

Thanks!

One think would have also done is braze the line set closed as soon as it was cut to prevent moisture from getting into it since it will be exposed till the next day especially with the humidity in the air from that snow.

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

Nice install

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

Awesome video! Looking forward to the next one.

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

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.

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

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.

Really Happy to learn from you man thank you!

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"

Safety glasses and adjustable wrench works better other way round.

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.

You did a good job getting to the point on how to replace a furnace

Now I'm ready when my furnace goes , I'm calling you .

Mud leg needs to be on the common gas line, that way it protects both the water heater and the furnace. The gas line to this furnace should never be installed at depicted. The main pipe should have been extended with the furnace leg being T’ed off the gas line same as water heater.

I couldn't help notice that when Dave said he turned the valve perpendicular to the pipe, he actually turned it parallel.

Quick pro tip… just get the new gas ball valve ready (pipe doped in off position). Loosen old ball valve until hand loose, then bam 2 sec thumb the gas and swap the ready to go new gas ball valve (that’s already in the off position🤯) and no more gas to think about just hookin up to unit and of course opening ball valve once gas piping is complete! I CANT remember the last time I turn the homes gas off to change a quick gas pipe out… safely😂

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!

This is a very useful video.

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!

I really like this KZfaq video.

I think i've seen and heard a wet/debris trap is needed for both gas lines. To help prevent cogged nozzles or miss fires sputtering

Excellent ! Awesome workmanship!

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!

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

I got two stage unit exactly like yours $425 but no ac. If you around 4 years ago would called yeah. Swamp cooler all rusted out I need run new pex 25 feet tbere galvanized elbows to copper shot. 1950 condo

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