Hi All, I recently had my heater/ac unit replaced, and it seems noisier than the old unit. Our old house has no subfloor, which I know is part of the problem, in addition to it being located under our dining room. I would like to quiet things down a bit and thought of cutting either ceiling tiles or thicker sheetrock to size and shove up into the joists. A traditional ceiling is not possible; too many things in the way. Which might be better? Anyone have experience with this? Any other suggestions? Thanks.
