Hey everyone I am a new first time home owner and I have 2 questions about my AC in my house. I'm sure over the years I will have many more questions lol.
1. In my hall closet is the ac/ heating unit. There is a metal duct going up to the roof to a vent. There is a 6 inch or more gap around the duct ( square) see picture. I can see into the attic. Should that gap be filled so that air isn't going into the attic? I found this gap because rats where coming down that gap into the closet so I want to close it up. Maybe with a roll of fiberglass around it? Is it supposed to have that gap?
2. My house is shaped like a U. The last bedroom is my son's room and if he closes his door at night it gets supper hot in side. It has a gap at the bottom of the door for the return and there is decent airflow coming out of the vent. And it's cold air. But I can't figure out why it's having a hard time staying cool at night. I used a laser temp gauge to check the air coming out and it's the same as the other vents in the house. And the walls and ceiling is about the same temp too. I'm thinking I either need more air pressure in the room, or more return out of the room. Any thoughts? Maybe a duct fan or register fan? Any thoughts would be appreciated!!
