Installing a Furnace and Ac Unit - Part 1

[@kenknight4560]

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.

[@vanhalenman60]

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.

[@FredD63]

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

[@BCummings]

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.

[@w-ols-7199]

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

[@salrodriguez8613]

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

[@JcKrecid]

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.

[@SwiperVahn]

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

[@MrPostFrame]

Glad it was helpful

[@bmalone0688]

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

[@ML-lg4ky]

A man can do anything he puts his mind to.

[@cdubs1723]

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. 👍

[@Kobe29261]

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.

[@MrPostFrame]

Awesome, thanks for watching!

[@karenh8538]

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.

[@lenrodgers351]

Glad you took your time ,very good info.

[@MrPostFrame]

Thanks for watching!

[@HoodHandyman]

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!

[@kevink2831]

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..

[@landscapesofenchantingmelodies]

Very professional. High quality! Well done.

[@MrPostFrame]

Thanks!

[@jonsmith9708]

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 !

[@ispeed7013]

Yeah judging by that ductwork he froze up on the first hot day

[@pwengert1]

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.

[@migueljuarez448]

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

[@MrPostFrame]

Thanks for watching!

[@marcgilbert1118]

Like your video well put together and detailed.

[@jeffjones4006]

Great job and thorough explanation your a good instructor.

[@RetroMemeMaster]

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

[@detroit.tone3134]

Thanks for showing me have one to do tomorrow

[@MrPostFrame]

Thanks for watching

[@darkdragoon197]

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

[@curransKids]

I agree, nice install. I also wanted to know why you punted on a filter in the return?

[@nneelix]

Me three. Recently did my own HVAC, added Media Cabinet and UV to the return plenum. Media came with MERV 11 but I upgraded to MERV 13 but I went with the largest Media Cabinet I could get my hands on to help cut down on the pressure drop.

[@markn.795]

You are awesome! Very thorough.

[@sarbbhamra6758]

Very clean job done.

[@MrPostFrame]

Thanks for watching!

[@billstjohn3132]

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.

[@will-smith-nh]

Great video. Thank you.

[@5822huron]

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

[@edwardsweat4806]

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

[@invernante1985]

How resourceful you are. Congratulations. Great video

[@charlesvincett84]

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

[@slingerland3g]

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 :)

[@jval8457]

I like " make the wife happier ☺ " 👍🏽

[@MrPostFrame]

Ha...happy wife...happy life!

[@JesusBelandriaG]

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 ?

[@shaunglendinning]

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

[@mmanut]

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

[@NathanTallack]

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

[@mikegarrison3101]

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

[@larryb131]

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?

[@craigs5212]

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.

[@princepa123]

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

[@NevinNolte]

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! 😂

[@mahmudrahman9855]

Thank you 🙏 May Allah bless you more

[@heliodoromadrid8723]

Thanks for your time buty I appreciate it

[@fifthamendment1]

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

[@happybearinc.9083]

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

[@hvac-rfreddy1275]

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

[@oscarplaza1219]

were did you install the air filter?

[@biged404]

Where are you going to pot your furnace filter?

[@StevieBzz]

Make the Wife happy!! Love it xx

[@AaronPowellvox]

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?

[@paulajones9956]

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

[@jodykershaw7701]

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.

[@amazegh2000]

Amazing

[@ronpossick]

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

[@Naatuma]

His filter rack is built into that 90 he attached to the side of the furnace.

[@eamjaey9794]

Happy wife, happy life, hands down man 🙌🏽

[@angelacen6518]

Is Beatiful job

[@juanantonio1215]

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

[@MrPostFrame]

Haven't finished part 3. Hope to get that out soon.

[@vintagegirl1961]

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

[@rharris7877]

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

[@mph5896]

alpinehomeair. also last setup I did I ordered plenum and return off eBay.

[@zo2913]

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.

[@ryanfriedrich7202]

Where did you buy your units I live in Oklahoma

[@keitha5188]

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

[@Balticblue93]

Seriously!!!

[@mikemmikem2758]

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

[@jamedcartwright3411]

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

[@Balticblue93]

You are definitely not wrong and it is going to leak everywhere unless he changed the install and removed the side evap pan and installed a different coil. The whole build is totally wrong from start to finishing. From ducting, return air, furnace size, wrong AC coil, no dehumidifier etc. If we learned anything, this is one way not to do things. Plus you can literally buy 20 x 20 ducting and should be sealing with mastic, silicon, foil tape and possibly internally sealing the ducts from Aeroseal. The return air is way undersized based on the space and size of the unit shown. He plans to go straight up with PVC ducting in an HE furnace out the roof? It needs to be angled 1/4" per foot horizontally. Where is the condensate pump and drain going? And I see no air filtration system or ventilator like an HRV or ERV. Manual J, D and S would be needed at a minimum but Manual T and P would be helpful also for best air flow and conditioned space.

[@Naatuma]

@@Balticblue93 That coil he used has a drain pan underneath, rewind the video and look at the door. Also how do you know what size his furnace is? If you don't know the coil had a drain pan under it, how do you know sizing? As an actual HVAC tech looking at his video, he cut that unit's return open to be roughly 16x24 (a gas furnace is 28-29" deep depending on the door profile) It has 4 burners and it's 21" wide. Makes me think it's an 80k btu 4 ton which running a 10x24 inch return is perfectly fine. For a HE furnace it's a preferred method to go out the roof, water drains back to the inducer easier and there are less restrictions. His filter rack is built into that 90 he installed, you can see the hinges on the door. HRV's and ERV are options, not neeeded at all but are nice if you want to pay extra. You bringing up energy loss/ductsize/airflow charts makes me think your a sales guy who has no idea what he's actually talking about.

[@mistervacation23]

Should a furnace go up to 5000 degrees?

[@andrewmullen4003]

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?

[@andrewdarbyshire9108]

Geo is nice but the upfront cost is huge compared to central furnace/ac or heat pump.

[@Erik_MN]

Am planning 40x40 post frame house with horizontal loop geo in SW MN. It is indeed more expensive.

[@WilsonNau]

Thank you

[@chessiekid4018]

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

[@andrewdarbyshire9108]

Way overkill, just wrap the duct with 3” insulation and we would be done. At least in my area codes are different state to state.

[@hulkinbrent6376]

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

[@andrewdarbyshire9108]

Places do hvac differently, most people in the south just use a filter grill. Lots of northern people like 4” filters at the unit.

[@slashrjl]

Is there a filter in this system?

[@alanm2842]

the filter rack is in the elbow he screwed on side of furnace

[@davidhill4711]

Like your final point...

[@andrewdarbyshire9108]

Fyi remove the horizontal pan for better airflow.

[@snakeeyes1649]

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

[@samuelgibson3913]

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

[@andrewdarbyshire9108]

Upfront cost I’m sure, plus the unknown of repairs and reliability. But reliability went out the window when he bought a Goodman system.

[@BeastPepper]

@@andrewdarbyshire9108 🤣

[@fstoll3]

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

[@vdarr1]

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

[@kman7222]

yahoo new video

[@marcusowens7267]

Where did he put the air filter

[@drewsahlstrom]

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

[@Cody-ye3ye]

Coil needs to face front of furnace, kills airflow

[@duartemonteiro7463]

😊💪💪💪💪

[@sargentpoptart4080]

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

[@christopherhaak9824]

He absolutely used a horizontal flow coil, per the drain pan location. It's a major f up. Just get the correct coil for the job. Lots of other issues also.

[@Sjrick]

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

[@wallaceloper637]

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

[@ThugMuffined]

Should’ve used duct board, not proper insulation

[@johnnyb8629]

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?

[@smithbrothers125]

As an owner of a HVAC company the fact that this guy is attempting to do this is disturbing. He doesn't have a clue what he is doing. He could have had the ductwork spray foamed and it would have been insulated and sealed in one shot. There will be serious condensation issues with the way he attempted to insulate the duct. And good luck when you have a problem, because he has no warranty.

[@alanm2842]

filter is in return elbow

[@BeastPepper]

​@@smithbrothers125 Yeah yeah if all potential customers installed their own units instead, you wouldn't make any money, we get it. Its hard to not be negative when you work in a field and can notice little things that bother you, but there is no major flaw in his work. Its funny, you can find these same comments on videos of any profession or hobby, people getting all territorial, their way or the highway. And using the pink insulation slabs isn't a problem if it was sealed correctly. Can't condensate if there is no fresh air moving around it. But personally I'd just use the "reflectives" r6 bubble wrap and call it a day.

[@Balticblue93]

@@BeastPepper No major flaws in his work? The entire install is pretty well incorrect from the start. The Manual J, S, D, T and P would pretty much put all that to rest. There is literally item after item that is incorrectly installed or the wrong product being used. Are you kidding me? I would write a book on why and how this install is not properly done. I would love to see some of your designs or installs, if you think this is just "noticing little things." Clearly you need some more training.

[@BeastPepper]

@@Balticblue93 I agree that the install was far from perfect but it's on his own house, and he isn't teaching people how to be professional hvac installers, only how HE installed his furnace. But maybe I need to find a new profession if people in my field are this perfectionist and OCD. I had a lead that was exactly this way. Cool guy off the job site, but I hated every second of working with him. 6 hour days turned into 12-14 because of his need to rip out and fabricate everything from scratch as some show of his skill. (for the record we were paid per job, not hour) Oh who am I kidding. Every profession has a cult of ignorant elitists whose only shred of personality is a reflection of their choice of work.

[@johnpyle8027]

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!

[@smithbrothers125]

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.

[@gregmize01]

you'll be fine. get some rest though.

[@dominicd2694]

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.
