Hi All, I recently purchased a town-home in the Northern VA area, and have a question regardng AC efficiency.
Is it more energy efficient to close off A/C vents in rooms that we don't use frequently (spare bedroom, basement, etc)? Or does it make more sense to open them all up and let the house breathe?
The previous owner kept most of the vents closed in rooms that were not often used, like the laundry room. I went ahead and opened them all up to circulate the air.
Is it more energy efficient to close them off? I own a 3 floor 2 bedroom 1500 sq ft. townhome end-unit.
Thanks!
Andrew
