Charlie: Sylvia from Anderson, Texas, says she’s getting ready to start new construction, about 1,850 square feet, single story, vaulted ceilings. She wants to know what size a/c and how many return air vents should she have, Tom.
Tom: How many square feet did you say, Charlie?
Charlie: Eighteen-hundred and 50.
Tom: Okay, and it’s gonna be kind of a tall ceiling. I would use probably 3 tons, and I can’t tell you how many, but I would have ’em in the major rooms. Like, I’d have a small 12 by 12 in the ceiling of every bedroom, and I would have one larger one within the open area of the house, and I think that would suffice just fine.
Charlie: Yeah, right, cool. But, you’ve long said that we should have a return air in every bedroom.
Tom: Every bedroom, just like I said, yeah. A 12 by 12 in the ceiling in every bedroom, and one larger one in the open areas. You gotta mix that air up, and in bedrooms, people like to close their doors, and so you want to be able to mix the air and be comfortable, and not in an uncomfortable room. And that’s why bedrooms, I always say, put an individual one in each bedroom.
