I bought a new house a few weeks ago had a new HVAC 13 Seer York installed. The house is 1800 sqft 4 bdroom 2 bath. I purchased a 70 pint dehumidifier and ran it for over 48 hours straight. The humidity level keeps showing 65 which I thought was high. I live in East Tennessee where the climate is mostly mild. The basement doesn't feel musty or wet. Should I just use a fan instead of the dehumidifier. I don't feel like the dehumidifier is doing anything.
