What we're gon na do today, it's uh furnace, we're replacing only furnace evaporator coal had to stay, and the whole furnace was higher than this one. Whether we have to build a piece from here to here whether we have to drop the coil and we decided to drop the coil, because we have long enough line set that we can move this down. The vapor coil was uncased coil. So it's sitting on a furnace and this piece we're gon na build a plane of new plenum.
Basically, it's raining outside. That's why we we're not gon na be able to pump down the system and, besides that, it's a scroll nightmare, so we're gon na just bend the line set. It's long enough. We have about five feet and it will sit on it.
Another thing because we're not going to be able to disconnect the line sets and you i have two holes here which twice it's come out with the condensate easy enough. You can remove it with the lines that you cannot so we're gon na cut a square piece here and keep this piece and then later screw this on our new piece. Basically, something like i don't know - maybe seven by seven we're gon na cut that and keep that piss pretty much now the coil is sitting there, we're gon na secure this and build the piece then later screw this piece on it. Because again, we cannot really pump down the system, because it's raining pretty much it now.
We're gon na take a few measurements and start building it. The first measurement, usually i'm doing measuring my height, how high my plenum should be. In this case i have 32. I will need a three eighths of an inch longer like a flange down there.
Three eighths - and this is a little bit hot, more than 32. So we're going to make very half already two and a half that's my height. My weight of the coil is 20 and it is bigger. 213.
Our box will make that 20 by 21 and a half, because we have 21 and a quarter and we'll screw that in in this case, we're gon na build uh this from two pieces exactly the way it was. We will have one piece in the front that will act as a door and we will make a u-shape from one piece screw it in first then put the door slot go and start building it. We have all the sizes 32 and a half high and 20 by 21 and a half okay, because we have 32 and a half. That's my height going to be - and this is 36 inch thought of that extra excess piece and our box should be 20 by 21 and a half 20.
That's the front, so i'm gon na cut this first then, because we're going to fill this two piece, one will be u-shaped and we will have 20 here 21 and a half here 21 and a half here, and the third piece will be the door which will Be again 20 inches and we will need extra one inch, one on each side. First, let's build this piece, and that gives us okay uh. This part that will go up enough, that work and the bottom i will use for my flanges. So i have to cut small triangles: usually i do about quarter inch opening and one inch deep so way to foreign with the slips into the three piece uh that view shape then so, because our focus should be, as we said, 20 inches, and now i have To cut my piece 22 that i will have extra ones on each side: okay, now we're gon na put that u-shape from that side, and the trick is to first drive into the sleeves, then kind of lift that up and put the flanges on the side of The furnace, so i'm going to go to other side, so, okay, the last thing we have to do is mark our hole for a drain line, connect the drain line and cut much smaller opening there that put this piece on top and screw it in then seal Around and it will hold it, but also later when we have the top cover, you have to scroll on this side and seal that side too. So now the easiest and fastest way, marking the hole is what i do from going to go. I can see from here and i'm marking the middle and the next thing you have to do. Let's mark the height and this piece gon na sit there, so i'm marking there and again marking my center. You can drill a hole, and this will be fine and the last thing we have to market my set where it's going to be okay, there's no easy way doing it, because that lasted in our way, so we're here here we find there about here.
The last thing you need to put slips here is: you will be able to drive your coloring, which means i pretty much it left is still here. Still there slips slow on the bottom fire her up. Thank you for watching.
Could you also use an expansion duct to connect the new furnace to the plenum box? Just asking. Excellent video though. Are you in Orleans ?
Great video. Quality craftsmanship. Thankyou
Beautiful
Wow those skillz 💯💥🔥🔥
Thank you for sharing. What gauge do you use for sheetmetal plenums?
dayum…he just made 3 sides outta 1 piece and made factory cross creases with a ladder. This dude is a baaaaaad maaaan
My head hurts watching this lol
Dude really did it the hardest and most time consuming way possible, looks like he needed 6 inches just buy a 6" furnace box next time lol
Good clean Service area Orleans??
Really refreshing to see old school ingenuity at work. Really nice work. Not many residential guys in my neck of the woods that have that level of skill with metal. Love that you showed accomplishing pro result with simplest of tools.
You need table, for laying out ductwork, save your back ! Are you in Ottawa ?
Amazing job Edward!!!!
It's like watching somebody do origami with metal!
That ladder trick was gold 💪🏼
Great work young man! You explained what you were doing very well. Thanks for your video!
Looks pretty good for building it on the floor. His cross breaks looked like they were done on a brake, not a ladder. I’m sure they will insulate the duct on the outside. He just wanted to show off the craftsmanship. Service area Barrhaven??
I wish I could use tin can to make my transitions. (Also the existing duct almost never lines up like that)
Outstanding job using the tools on hand. Did a better job than most guys with a shop brake. Great video. Check out a “ Hensler Bender” great tool for your van.
Great duct work! Should a coil not be atleast 6 inches from heat exchanger?
Very nice! I struggle sometimes using a portable bender. I think you could use anything todo a bend and it would still look good. lol
Nice job!
That box will sweat with no insulation. Service area Nepean??
I hate to be “that guy” but I have to point out that he did not Insulate the case. But I would also like to say that his craftsmanship is on point, and his dedication to meeting his customers need is above and beyond. Well done sir 🤙👏
This exactly why I subscribe to this channel for the great information. A ladder used as a break, never thought of that in the last 30 years of doing HVAC work. Who says you can’t teach an old dog new tricks, this trick I will remember.
I don’t even understand how he gets such clean bends and cross breaks with a ladder.. this guy is incredible
Really good job. Keep going
You are awesome
Wow! That was clever!) Are you in Barrhaven ?
Nice job, like the ladder idea. I always thought you were suppose to leave at least 2" in between the evap coil and top of the furnace. I know most guys want at least 6" above the furnace. Sometimes you don't have the room, but it looked like you could have raised the coil quite a bit. Great job though.
Nice Are you in Kanata ?
This is cheating, he has room to work around the entire unit.
Shaaazam! Dude is 100% about his business. Nice job! Using the ladder was stellar! Haters don't even open your mouth…you'll just look stupid.
Nice job.thanks for sharing👍👍👍
Wow
I love this guy! He's a machine!
Give this dude a raise. Guys like that don’t just walk in off the street everyday.
Good job !
I am a 49+ year HVAC&R tech and sometimes find myself having to do installations and sheet-metal work occasionally, thanks for these videos.
Your never to old to learn.
No insulation??
Do coils not need insulation to prevent sweating?
Kick ass man. Respect.
The box will sweat, why didn't you wrap it with Reflectix?
Guys a magician
Professional done my friend. Even an old guy like myself learned something today. Service area Kanata??
I'm surprised he didn't address the rusty evap coil pan.
Awesome 👍
Thats how I use to do it on my side hustles. Get that man electric shears and a Malco Porta Brake. Good looking plenum for what he had to work with. 👍👍that show experience.
PS- I would recommend to younger guys watching this to NOT move a 20+ yr old evap coil. Someday that will bite you in the ass. Customers will play the "it didn't leak before you touched it" game. Are you in Nepean ?
It had never crossed my mind to use the step ladder to do the cross breaks! Very talented guy working out of a five-gallon bucket; fortunately, in my market it not good practice to replace only one side of the comfort system, unless the customer absolutely cannot do it any other way.
Great job 👏
Hey quick question do you guys use P3 duct. Or phenol
Nice job!
good job bro that was clean
