During my DIY full gut 2 family remodel, I’m installing a fully ducted furnace and ac. In this part 2 video I tackle the main trunk line and connecting all the supplies / returns.

Really great videos man! I think you'll do quite well as a KZfaqr - keep plugging along! Well done from 🇨🇦!

Looks Great! Definitely a some great craftsmanship. A few major flaws on the duct design and the way you attached the coil to the furnace. First off is the RA , not good to blank it off like that especially with AC involved. Next the way you attached the coil to the furnace would be better if you had made yourself one of those nice transitions. The supply looks pretty good, hopefully for your sake you did the numbers . Ductulaters help

Thank you! Appreciate the input. You’re 100% correct the return size is below the minimum by one inch in both dimensions kinda keeping my fingers crossed on that one, but I don’t think it will matter. Per the installation instructions the coils permitted to mount straight to furnace with no transition but I did make a very small offset to help in that regard. I had some help with sizing and all supplies have dampers to be balanced later.

We either have a conversation, or we listen to music. At no point are both going to occur at the same time.

14” return isn’t very big. Not sure what your tunnage is. Hopefully with the one for the bonus room you’ll have enough return. Your work is excellent though. I’d hire you for sure!

@GreatScottHomes43 8 күн бұрын

well I hope with the additional 8” we should be good. 2 ton ac, thank you so much!

@@GreatScottHomes43 awesome. That sounds good. Be sure to check your fan speed on the furnace. It looks like that one probably maxes out at two tuns but it doesn’t hurt to read the manual. Again, great work on this system.

Awesome work! keep it up and your channel is going to blow up man! - Can i ask how you were able to determine what size unit / air handler you needed and what size and type ducts?

@GreatScottHomes43 11 күн бұрын

Thank you so much! There was never a formal manual j or anything done for this apartment it was just sq footage based. From what little knowledge I have you have to screw up pretty bad for a unit to be so over or under sized, that’s it problematic. As for duct sizing I would recommend watching another video specifically for it, not enough space in the comments for that topic, but as for individual supply ducts, for the most part are all slightly over sized with dampers so I can perfectly balance the system later. I did bounce a few things off an hvac friend which helped me sleep at night ahah. 80kbtu furnace and 2 ton ac.

Did you read the instructions dude? There's a big section in there about horizontal left and right installations about required transitions when evaporator width is larger than furnace. Be careful with putting ducts directly on to end caps, bad balance and static issues, velocity and static are not the same thing however they affect each other. Trunks lines you would want to come out of the sides of trunk, the 8" side.

@GreatScottHomes43 2 күн бұрын

Appreciate the input, the coil’s installation instructions allow for no transition but as you saw I made a tiny one to help a little. Yeah, the supply on the very end was intentional. With that particular supply being significantly longer than all the others, I wanted to steal as much static pressure as possible to actually help balance later. I’m actually not to sure about the take offs on the smaller dimension of trunk, could you elaborate?

25 year hvac guy here. Does look good for not being a pro, but looks arent everything. you should NEVER blank off return of unit. they are sized that way for a reason. and then putting a 14" flex only is no good. not only will furnace sound like a freight train but it will screw up static pressure of ducting and likely shorten the life of the system. should have a 16" or better yet 18" and 24x30 return intake. not sure where youre located but here in La. with our high humidity, heat exchanger would rust prematurely and compressor would likely have a short and miserable life

located in New England and there’s an additional 8 inch return for finished attic
