Im trying to DIY fix my ducts
I hired the wrong guy. He removed a 10+ year old furnace and unsealed/uninsulated ducts from vented attic (Yay!). Then it went downhill. He installed a oversized 96% 2 stage condensing unit in my heated basement, and now The outdoor ac unit bangs loudly as it turns off its short cycling runs. It’s return air (trunk, plenum?) Is too small to fit the size of filter the manual says it should have. Unsealed ductwork (im working on it). Panned return. The pvc exhaust and intake run out my rim joist together directly touching each other and end touching eachother which is great for intaking the exhaust. (🤬) and the duct layout design is utterly incomprehensible to me, and the condensation line is mostly fishtank type tubing instead of pvc with a trap thats higher than it should be-(manual has a picture with a arrow saying ‘Dont install trap above this’) gahhh it’s just a bit worse than average for my local hvac companies work, in my experience.
No, I wont waste my money calling in another company. Im going to take measurments and see if energy vanguard will do the magic number calculations for me on duct design etc. And then i will replace ductwork myself, learn as i go.
Air Return, no more panning! The return is supposed to intake an equal amount or more of air as the supply side blows- why am i not finding register boots (for floor or wall) that are larger than 6x12x6? Menards & Lowes sell many vent covers of a large size but no boots to match them? (Panning, ick) Im assuming I may have to form a boot on my own to match those sizes or else run multiple returns in rooms? I should just wait till i get info from E.V (or whichever willing company) but im a impatient tinkerer so im wanting to get in some practice on building duct now by replacing the panning. In addition to any suggestions on large boots I could use any suggestions on .coms or videos that are useful for a advice. I will not be touching the units themselves, no electrical or otherwise. Im just turning my hand to hard metal duct only.
2nd question: i need to replace the unit too but id like to wait as long as i can, t(budget is tight)i be resizing ducts later on when i buy the much smaller and correct sized unit?
