Energy efficient tight home construction with low infiltration rates reduces sensible demand and air conditioning run time, resulting in less latent humidity removal when it’s needed most. Your HVAC equipment includes an oversized air conditioner/heat pump. The quick cycling does not allow enough time to remove the latent load. Homeowners often must overcool their homes to remove humidity, making them chilly even in summer. Many times this happens when the thermostat drives temperature under the set point to achieve desired relative humidity set point.
