Oversized unit and high humidity problems?
When I moved into my house, my dad told me that he had a bigger heat pump installed than what was required - thinking bigger is better. I had no idea at the time that this was actually bad instead of good. The house I'm living in is very old, and this is the first time central heat and air has ever been installed. Ever since we moved in, we've been having very high humidity problems. Lots of mold (I think it's pretty harmless though, but I am constantly cleaning it) and sweating windows, sometimes even condensation on the walls, etc. It tends to be worse in the winter than in the summer. I never thought to connect this problem with the heat pump, but now I have. What can I do? Installing a new unit is not an option, due to money. How can I live with my current heat pump and control these humidity levels? I do have a dehumidifier - I keep it in my bedroom where the humidity tends to be worse. I don't run it all the time though. I have Damp-rid buckets in several rooms. I read online somewhere that setting the thermostat fan setting to "ON" rather than "AUTO" would help, but then upon doing more research, some sites suggest this could make the humidity worse. Should I have my fan setting at "ON" all the time? Any advice would be greatly appreciated. Thank you!
