Today’s AC Systems and Heat pumps, despite their efficiency in temperature control, often exhibit limited dehumidification capacity. This combined with mechanical ventilation and occupants can result in indoor relative humidity levels exceeding the ASHRAE recommendation of no greater than 60% for extended periods of time. This compromises occupant comfort, indoor air quality, and building integrity. The presentation will address the importance of dedicated humidity control, why homes are now seeing moisture issues, and detail how advanced dehumidification systems can integrate with heat pump installations to provide precise moisture control without sacrificing energy efficiency.
