Dehumidification

Home owners/buyers should be aware that humidity control (or moisture removal) is only a secondary benefit of standard air conditioning (i.e. moisture is only removed when the thermostat is calling for cooling).

Although currently accepted HVAC load estimating methodologies attempt to maximize the moisture removal capabilities of standard air conditioning, it does not ensure satisfactory results, particularly in warm humid climates. Humidity control can be improved with controls, the use of variable speed air handlers and the use of multi-stage or variable speed compressor systems.

Additionally, whole-house dehumidification systems can be installed to precisely control humidity independent of the air conditioning system. Those with mold allergies, asthma or other respiratory concerns should be particularly aware of the benefits of interior humidity control.
