Installing a Furnace and Ac Unit - Part 1 

30 years ago you could gain this kind of knowledge from This Old House, not any longer. Following this build you could learn something about all the trades and how to build a structure like this. Great channel and hard working nice folks.

The planning that this shows is staggering. From framing to electrical, ductwork and vents... to knowing exactly what units you were going to use. Obviously you you never said "we'll figure it out when the time comes." And that's why your results are always stellar.

10 years in hvac and im super impressed. its impractical from a business and sales point but you took that to its fullest. so long as the static pressure is good thats a solid system, much better than you can buy without custom preferences.

Your plenum is actually a standard 20 x 20… Which can be bought at a supply house along with the endcap and the takeoff that you would need on the top

Fascinating again Mr Marshall, I simply wouldn’t know where to start. Such wonderful craftsmanship and a pleasure to watch. Thank you for posting. Kind regards Karen.

Hi Paul, Hi Emily, I live in England and I arrived on your videos at episode eight and followed you ever since and its been a pleasure to watch you both build and cope with family life all at once, but what amazes me most of all is your knowledge on how to do all that you have done, you are a very clever man.. I shall carry on watching until the end and its nice to see Emily here as well.. Best wishes to you all..

This video is so good. Clear, no BS, and you preemptively explained every question that came into my head as I was watching.

This is the most clean and professional install I have ever seen, very well done.

I wish you posted this 2 weeks ago 😂. I am a builder and DIY'er and ran into the exact issue. My good friends are HVAC pro's but are slammed. They at least helped me order what I needed. I figured I would disassemble the old equipment and have them install. Well I was very capable of the removal but when it came to reinstall they still were slammed. So I started with the install. This video is rear and I would have benefited from it greatly. I look forward to watching the next videos. I was fortunate enough to have the ductwork longer than I needed and was able to cut it and fit. I also finally got one of them to rework the two lines back to the new units and charge the system. I had to watch a bunch of videos to get an understanding of each step. Your video so far is exactly what I needed with start to finish.

Excellent work as usual, Paul! Is there anything you don’t know how to do? Your knowledge is amazing! We really enjoy watching you & always happy to see Emily & your family in your videos as well.

So excited for these! Just got my plumbing ticket and want to specialize in this line of work

Great job and thorough explanation your a good instructor.

Should’ve put cross breaks in the plenum…gonna hear a lot of popping probably. Also, pull that coil and remove the horizontal drain pan. Install will say to, in order to get maximum efficiency. With a TXV present, I’m assuming that’s the goal. Other than that, looks good. 👍

I'm not in shape enough to do all that anymore. I gotta give this guy all the credit in the world to be over 50 doing all this by himself. He's a beast!

As usual, so interesting and informative. Thanks for sharing.

Great video, very informative and interesting. Thanks for sharing Paul, neat job!

You are awesome! Very thorough.

This is absolutely fantastic! Really appreciate it! I'm gonna have a Pro come in to check the final work but this should get me very far along before I need professional help. Replacing an old oil furnace.

Very professional. High quality! Well done.

Exactly the information I needed! Didn't know if there was a seperate blower for the A/C unit. Now I know!

Nice job on the tin bashing....looks great...

Very clean job done.

You are a bloody legend mate!!! Keep up the great work! :)

Thank you 🙏 May Allah bless you more

Glad you took your time ,very good info.

Great video. Thank you.

Like your video well put together and detailed.

I'm a builder of over 30 years and skilled tradesmen specialize in HVAC, plumbing, electrical etc .projects like this should be left to pros because if you don't have correct ductwork and furnace combo you can cause big problems !

Your series among other youtubers have been such a great inspiration to the point my wife and I are highly considering doing such and endeavor ourselves :)

Your skills and knowledge truly amaze me Paul. Is there honestly anything you can't do?

Thanks for showing me have one to do tomorrow

Where I live (Utah) we do it differently. Still it’s great seeing how other do it and get knowledge on other ways I can work better

He doesnt sound like a service tech but he seems knowledgeable enough to install.. His sheet metal also has no crossbreaks..

Thanks for your time buty I appreciate it

Amazing

Thank you

Is Beatiful job

Truly amazing work!! Well said, a happy wife, makes for a happy life.

I've been worried about you getting your AC hooked up, Iowa heat is no joke! Looking forward to the final video of you two standing in front of a vent with cold air blowing out! 😂

You know what trhey say, "Happy wife, happy life!"

GREAT STUFF, AIR TITE, VIDEOS ATE TOP SHELF‼️👍👍. Vinny 🇺🇸

Thanks, nice video. Did my own furnace install many years back. If I had known about the adjustable plenum that would have saved me a bunch. The sheet metal shop screwed up so I had to modify anyway. I had seen the S cleats (didn't use them) but never knew how they worked. Are you going to do your own refrigeration evacuation and charging? Thanks again.

I like " make the wife happier ☺ " 👍🏽

WOW that's a lot of work, but you are amazingly Smart

You should build a platform underneath the furnace and sit the furnace at the top instead of messing up with the furnace cabinet

Make the Wife happy!! Love it xx

Like your final point...

Love the work it is just very unfortunate that there will be a great amount of air lose in the return line and the plenum because it appears that nothing got air sealed.

What will you do about mold accumulation in your duct work. Had some work done and the man found mold on noise batting. He said there was something to combat this but I get confused when I try to research this subject. Please help this old man.

Not sure if you reply to questions or not but I’ll give it a shot. I bought a duplex and it has radiators so I’m thinking about the most efficient and economic way of transitioning. Can I install a full system without necessarily hooking up the furnace and then at some point hook it up but yet have the AC fully working ?

Iam doing a reno on my home iam at the point of the a/c system....I have the rheem units can some tell me where can I get the box that come off the supply and return.....iam in Cincinnati ohio.....or the air duck parts to build the supply and return like he did...and a great job that you can learn a lot from this channel

As usual another great video! Is there anything you don't know how to do!!! Lol. Paul, I was wondering if you could comment on the design of the HVAC system. How did you calculate the size unit you needed for the size of your building, and how did you design the duct work system? I have seen a lot of videos showing these Cadillac units that cost 7% of your budget not including a design service. That is simply out of reach for the average homeowner wanting to build a Bardo. Was wondering what your thoughts on this are?

Fyi remove the horizontal pan for better airflow.

How did you seal the back of the return air duct? It appears that you left a gap?

were did you install the air filter?

Happy wife, happy life, hands down man 🙌🏽

Where are you going to pot your furnace filter?

Is air from the blower supposed to be blowing out from the base of the cabinet into the room?

Where did you buy your units I live in Oklahoma

Nice install Paul, very informative. But had some questions 1. What size units did you go with? 2. Why no filter in return air?

Just curious Josh but is your second floor utility room soundproofed?

I’ve never seen anyone wrap duct like that. You did it the hard way but you did a great job. Lol Btw where is your filter rack?

My suggestion, buy a couple replacements of that computer board. In 10-15 years when it breaks down for no reason at all, you wont be able to buy that board or it will be ridiculously overpriced. I have furnaces from the 80s all the way until now. The 80s furnace runs perfectly, not a problem. The new high efficiency(computer controlled) models, break down without warning and at the best time... winter blizzard days.

Should a furnace go up to 5000 degrees?

Great videobut I did not see a filter rack. Did I miss something?

I couldn't find your part 3 can you send me a link for that thank you very much

Isnt the air filter usually on the return air or u have a different system for that?

I just wonder if the HVAC people would be this efficient? Or would they say this is overkill?

Where did he put the air filter

How did you screw the coil to the furnace? You skipped over that 😩

Do you have an air cleaner installed on your furnace system?

Is there a filter in this system?

I'm surprised you've gone with a furnace, I thought a ground source heat pump would be much cheaper given the space and land you have?

yahoo new video

Well real real quick you installed a horizontal evaporator coil vertically. It’s gonna drain strain down. Am I wrong?

im so glad these homeowners and handymen can only get goodman equipment...instead of proffesional equipment!!!

😊💪💪💪💪

I am looking for a video of airhandler install mobile home...GMom and 2 teens

Is there a particular reason you chose a traditional HVAC system instead of a Mini Split system?

Am i the only one who doesn't understand how this unit is going to catch the condensation? It looks like he used a horizontal flow coil? The condensate pan is vertical and will not catch anything so in theory all the condensation will fall right on the heat exchanger and blower? Please correct me if im wrong i just cant see it any other way

How much to have you come build my house?!?

Coil needs to face front of furnace, kills airflow

Will I thought you just alumni tape it, but always got a professional to do my just bing honest

Wow he even does HVAC !! Is there anything this man cant do ??!!

Should’ve used duct board, not proper insulation

I've thought it, but never said anything. Why did you ever go into police work with the skills you have? I grew up in everything construction and am as OCD as they come. I mainly do masonry work and I will saw a brick where others will chip or break them with a hammer and they aren't wrong. lol You could work on anything I have!

I know your a dabbler in this part of the trades but your making me cringe bro, you had all the tools to do S cleats AND drives to extend your plenum. Watching you struggle lifting and setting the cased coil was panful as well, next time take the coil out of the box, it slides in and out easier than it was trying to heave it all together. I would have run the return all the way down first in one piece assembled prior with S and D, connected it to the take off. then positioned the furnace in place, its like tiling in the corner of a room and working out and it enables you to tape your seams. I would cross broke the plenum too, there are two tools that I would get if your going to do this work regularly, a duct stretcher and a Hensler Bender. You can also make your own seams without the use of a Pittsburg machine, just with bar folders. Also, where's your filter rack?

It's not crossbroke

This is really, really bad. There are so many things done wrong here. Stop what you are doing and hire a professional to install good equipment and do it right. The HVAC and plumbing systems are the lifeblood of any building and you are killing it. Stop and think about what you are doing.

Congratulations, you just voided your furnace warranty and your furnace may not function properly. You are not allowed to position your evaporator that is sitting on top of your furnace the way you did. The evaporator coil has to ALWAYS face front and not to the side the way you did. I am not going to educate you, because these projects should only be done by a pro, doesn't matter how busy they are. This is why I hate videos by homeowners or I assume you are a carpenter (by your title) giving wrong advice. Your evaporator coil doesn't put cold air into your house, it absorbs hot air and sends it outside to your condenser, who uses pink board to insulate ductwork in the attic, they sell the proper insulation and which will pass your local codes, your picture with the furnace in the basement and you have round pipe connected to your furnace plenum, you require a PTO and rectangular duct and not round pipe like you have as you will affect your static pressure. I can go on and on, but I will give you advice, HIRE A PRO. Licensed Refrigeration Mechanic/Heating Technician Toronto, Canada and NATE Certified USA.

So you guys use S Locks on all four side's? No drives?

why no cross breaks?

U did a wonderful job bud thanks .. I think u should use 🧤 when your Instructing your viewers just to show safety 🦺 1st .... Thanks again for the vid

How resourceful you are. Congratulations. Great video
