Will closing a door keep a room cooler?

When you shut a door, the air that’s still blowing out of the vent builds in the room, pressurizing it. Only when you finally balance the pressure by opening up those closed-off rooms will your air conditioner be able to clear the air and cool your house at peak efficiency.

How do you keep a room cool with the door closed?

If you’re spending most of your time in one room, consider closing the doors to the rooms you aren’t using as often — like bedrooms or bathrooms.

Why does my room get cold when I close the door?

Closing a bedroom door reduces the air flow into the room and the air flow through the system. When the system puts air into a room and it gets trapped, it pressurizes the bedroom. This positive pressure forces the cooled, or conditioned, air out of the house through any opening in the room that the air can find.

What happens when you close the door on an air conditioner?

If you close the interior door to a room while your air conditioner is in a cooling cycle, the air that is pumped into that room will be trapped inside.
