I have my air set at 77 the average temperature outside has been way above 80. During the day the entire house is cool with all the doors to the bedrooms are open. When I close my bedroom door at night the room is hot even with a ceiling fan on. The other rooms in the house are fine. What is happening in my bedroom the vent is not clogged and the filters are new.

Assuming you have one central return air vent.

When you close the bedroom door you prevent the air conditioner from pulling any warm air out of the room.

You can't put any cold air in the bedroom unless you pull the warm air out.

Too much back pressure and air flow stops. Either keep door open or cut the bottom of the door so air can flow out.
