Sometimes, humidity or dampness (water vapor) in the air can supply enough moisture for mold growth. Indoor relative humidity (RH) should be kept below 60 percent -- ideally between 30 percent and 50 percent, if possible. Low humidity may also discourage pests (such as cockroaches) and dust mites.
You cannot reliably control mold and mildew growth using only the air conditioning (cooling) system. To prevent mold and mildew growth the indoor RH (relative humidity) should not exceed 55%. In hot weather the air conditioning system does this fairly well.However the highest relative humidity in the home is likely to occur during mild weather when your air conditioner is not needed much during the day.ou cannot reliably control mold and mildew growth using only the air conditioning (cooling) system.
