    Keep humidity under 60% and you will be fine. Have the evap coil inspected once a year.

    Suggest <50%RH if any carpeting on concrete to avoid condensation/mold between the pad and concrete. <50%RH also eliminates dust mites in upholstered surfaces like beding and carpeting. Pay attention to the %RH during wet cool weather with low/no a/c load. In green grass climates with adequate inflitration/ventilation, 90 pints of dehumidification per 2,500 sqft. of living space maintains <50%RH without any a/c operation.

    This is how the data from a house with a good dehumidifier looks. Had a dry week and followed by a rainy days. No a/c.

    It's what the auction was for.
