What is my best solution to remove HVAC & ducts from cold attic?
I bought a home 7 months ago. 1953 ranch style, 5 on 12 gable roof, 2 gable vents, 4 “turtle” vents on southern side midroof & supposedly soffit vents. Add in a hvac and flex duct that was never sealed and about 4 inches of beat up kraft faced fiberglass laying willy-nilly over the original loose fill (I’m guessing its rockwool?) Attic floor has never been air sealed. And of course all of this is in cold climate 6a. This is how we roll in South Dakota, yee haw. The very moment winter started I realised my home has severe heat issues and thus my self education for survival in this new house began. I never heard of ice dams, attic moisture issues, didnt even blink when I was told hvac was in attic. Ha! Anyway I’m air sealing attic and installing baffles currently. Im snaking a camera into the formerly insulation blocked soffits, I have yet to find any actual venting holes in the wood soffit that my aluminum vent panels cover. I’ll add insulation when I’m done sealing and baffling. I’ve discovered i have two layers of ceilings pressed together, I think only in some areas (WHY WOULD SOMEONE DO THAT?) so I cant get at the interior top plates for air sealing? Any special instructions for this weird situation? I am able to get exterior top plates, duct boots, etc and so forth. I’m currently gathering roofing estimates to add in soffit vents & change current venting. So far the roofing companies either admit to not understanding proper venting (yay for honesty!) Or they propose venting options I know are wrong from reading your site. What would you suggest for venting my 873.8 sq ft attic? (House/attic is L shaped). My next project will be to remove the hvac & duct from my attic. My nice finished basement has more than enough room. I understand this will be a very expensive project. Question is, if I’m ready and prepared to write some serious checks for improving my home heating and air system- should I be looking beyond just moving the unit and ducts? Now, dont get super crazy on awesome ideas that cost intense amounts of money. I honestly dont know yet what a reasonable price tag on just moving and reinstalling by itself is. 5k-15k? Ick. But let’s say I’m willing to invest up to 25k or so doing something wise which gives eventual paybacks. I assume I’ll live in this home for the next 40 years until my daughter starts eyeballing retirement homes for me. What would you suggest for my heating situation? Thank you for all that you do with this website!
