As a Midwesterner, it is absolutely bonkers to me how common it appears to be for HVAC systems to get installed in attics.
Don't do that. Stop doing that! WTF?
That's bad enough, but then you go and run the ducts up there, too?
Y'all.
If you keep the system and the ducts within the space you're trying to heat and cool, you don't have to account for any losses, now, do ya?
Put the air handler in a utility closet. Run ducts /below/ the ceiling. Enclose with soffiting if you must.
The end.
This is a test rant for a future video that may or may not happen.
But seriously, I cannot fathom how HVAC stuff in attics (or crawlspaces!) got normalized. Especially in new construction.
You virtually never see that around here (the most common application is old homes with radiators for heat who want to add central air) and for good reason!
@TechConnectify luckily my attic has a lil fan that will blow hot air out during the summer, completely unrelated to the houses full AC but makes it nice getting stuff up/down.
@haifisch Those are great!
