Don't want this to get into a big discussion like the other thread on returns being added but what would help a room be more comfortable (same temp as rest of house) more registers or return?
Our house is a ranch with our bedroom being on the short side if looked at the letter "L". So we have three exterior walls. If we leave the door open the room stays the same temp as the rest of the house. If the door is closed it becomes hotter in the summer and colder in the winter. I know wall insulation would help but is a larger register or return the proper fix and which one? The whole house has the same size returns for each room.
Any other info needed just ask.
