I noticed that basement was unusually warm in late January (even though it's been a mild winter so far in Chicago) I noticed there was a lot of heat coming from the furnace exhaust near the furnace. It's as if there is a loose connection. 2 questions;
1. Is this heat dangerous? Common sense says exhaust is not healthy.
2. Should this be happening... the "heat leak"
The house was built in 1995 and I bought it in 2011. When I first moved in, I noticed that the ducts had many leaks at the joints. I was told to buy foil tape and wrap'm up. I guess it worked but the air in my 2nd floor master bedroom is still weak, that's another topic
