Does an Air Conditioner Dehumidify?

During the summer, your air conditioner plays an important role in regulating temperature and humidity inside your home.

Does an Air Conditioner Dehumidify?

Yes, air conditioners serve as whole-house dehumidifiers through the action of the refrigeration cycle. When the blower fan engages, warm indoor air passes over the cold evaporator coil and the air condenses. Moisture is separated from the air and collects in the condensate pan, eventually draining outdoors. The resulting dehumidified air enters your home through the supply duct system.

While a central air conditioner provides dehumidification as a byproduct of its natural operation, it is important to remember that the primary function of an air conditioner is cooling your home.

Is Inadequate Air Conditioner Dehumidification Bad For Your Health?

Excessive humidity can create a multitude of health issues if left unaddressed. Mold, fungi, and bacteria thrive in environments with high humidity and can negatively impact those with chronic respiratory conditions. Established mold colonies should always be eradicated by a professional indoor air quality specialist.

What are Common Reasons an Air Conditioner Won't Dehumidify Properly?

In order to properly dehumidify your home, your air conditioner must cycle properly. Most dehumidification problems can be traced back to one of the following issues:

  • Incorrect Sizing: If your system was sized incorrectly, the unit may not run long enough to adequately dehumidify the air. Whole-house dehumidifiers can help compensate for poorly designed AC systems.
  • Obstructions: Clogged filters, dirty coils, and ductwork restrictions slow the airflow, which degrades the efficiency of the refrigeration cycle.
  • Equipment Problems: Low or leaking refrigerant will reduce the amount of moisture your air conditioner can remove from the air. If you suspect your equipment has malfunctioned, you will need to arrange for an air conditioning repair.
