I move into my new condo(about 2500 sq.ft.)about a year and half ago. My basement is finished, and was a little cooler than the upstairs, so I purchased a dehumidifier. When it runs the temperature in the basement is like the upstairs, so it works. The trouble I have is that IT RUNS ALL THE TIME!!!! I empty about 2-3 gallons of water from it every day. This happens no matter if the heat runs or the airconditioner. The HVAC man says that my house is too tight. Can any one help me?
