Recently had a/c installed and its working great but holy crap is our basement ever freezing cold. I’ll put a temp sensor down there but it must be 3 or 4 degrees colder then the main floor, which is 3 or 4 degrees colder then the upstairs.
Anyways I was down there while the a/c was firing away and there is a breeze of air escaping the furnace from these 2 locations.
Along the metal channel (which is poorly sealed with some sort of caulking) specifically at the corner there is tons of sweet, sweet chilly air is just blowing out. And then behind the humidifier there is a sliver of opening where even more air is escaping.
I have no idea if my install was poor from the home builder or if the a/c installation messed with any of this but can I just seal those areas up with that duct tape and help push more cold air through the ductwork. Or is there a better more suitable solution?
