Dehumidification: Why an Air Conditioner May Not Be Able to Do It Alone

Most Long Island residents are familiar with high humidity during the hot and muggy summer months. Homeowners can usually rely on their air conditioners to remove that humidity. But sometimes, even when an air conditioner is going full tilt, it may not make a home feel sufficiently comfortable. Perhaps the A/C is older and no longer up to the job. But some homes just naturally attract more moisture than other homes. And in this situation, an air conditioner may not be able to do the job alone. 

Too much humidity in your home can have numerous negative effects, including:Dehumidification: Why an Air Conditioner May Not Be Able to Do It Alone

  • Respiratory reactions to mold, mildew, dust mites, bacteria and fungi.
  • Unpleasant odors.
  • Foggy or sweating windows, warping of wood materials, peeling wall coverings or paint and stains on walls and ceilings.
  • Heavy, muggy air quality and temperatures that feel warmer than they actually are.

Experts agree that ideal humidity in a home should be 30 to 50 percent. Anything over 60 percent can make you feel sticky and clammy and can invite mold growth. In this kind of situation, extra dehumidification is needed.

Dehumidifiers are available as small portable units, designed to treat the air in a single space–such as a basement–or whole-house units that cover every area that your HVAC system reaches. An advantage of having a whole-house dehumidifier is that you can use it when temperatures are milder–in the spring and fall, for example. The dehumidifier alone will make you feel comfortable enough to keep the air conditioner off.

Dehumidifiers work by drawing your home’s hot, humid air over a set of refrigerant-filled coils that absorb heat and simultaneously condense air moisture. This condensate drips into a collection vessel, where it’s either drained away or remains until emptied.  Removing moisture from the air lowers its humidity to the pre-set level, with the unit typically turning itself off when that level is reached.
