Is there a reason for all of my AC vents in my new house directed toward the windows and walls or is it better to have them turned around to blow into the center of the room?

Answer 1

Hi, The system you are describing is often refered to as a perimeter system of duct design. You are lucky to have it if you do. The vents pointing toward the windows is normally good because it attacks the main heat load at its main source before it gets into your room and blends with other air. It's a good system and usually takes more effort and thought plus expense by your installer.
Yes, you can turn them if you want and feel this is better for you.
Some people do that simply because they want the air to blow on them directly. Hope This Helps: jimiwane
