My master bedroom is hot! Should I install a return in my master bedroom?
Here it is thanks. A return duct will help the air flow into the room when the door is closed. Up sizing the supply and dampers to to help provide more flow may also help. In my last home I had 2 dampers that I adjusted 1 for up stairs and 1 for down. More air to the upstairs in summer when it was cold and more down in the winter when the heat was on. Since both seasons are not comfortable a return would be the first change then an upsize to the supply.
