This may be a case in which I'm looking for trouble where there isn't any, but I'd feel irresponsible if I didn't ask.
My mother-in-law is thinking about buying a condo. When I asked her a couple basic questions about the HVAC setup, she told me that all the vents--both supply and return--were on the ceiling. Apparently, people who live there think it's fine, and perhaps that's ultimately what I should go by. But to this layperson, it just seems inefficient for heating.
I probably can't provide great detail about the place. I know it's a single story, first-floor (with a "ground floor" beneath it) apartment. She likes "bright and airy", and it has a balcony, so I'm guessing there's a fair amount of glass. This is in the D.C. metro area.
Thanks in advance. It's likely not a big issue, but I'd prefer that she be as informed as possible before spending her money.
