A game room in a house is a space used exclusively for leisure activities. Whether your favorite recreational activities at home include movies, music, video games, board games, or big games like pool and darts, you need an awesome game room to show off all your toys and to keep your guests coming back for more. Closed vents—Closed vents in rooms can cause them to be hotter than other rooms. Open windows—Your conditioned air can flow out of open windows, leaving uneven temperatures in your home. Air duct issues—If you have any kinked or crushed supply ducts, certain rooms won’t get enough air.
