Ceiling Mounted Air Intake?
We are getting ready to install HVAC and the builder has recommended using ceiling-mounted air intakes rather than the traditional floor-mounted intakes. He claims this is a more efficient system. I'm not sure how the intakes on the ceiling will look, and if it will create dirty areas around the intake. 2-story house with three units, if that matters....
Is anyone familiar with this set up, and pro/cons?
