Whole House Dehumidifiers


All homes are in need of humidity control because of our southern climate. In Georgia we need humidity control year round.

Air conditioning alone can't satisfy your home's humidity requirement. Your air conditioning system is designed to control temperature, not humidity, and only removes humidity as a byproduct of cooling. During the spring and fall seasons when it’s still cool outside but damp inside, your air conditioning isn’t running and your house is uncomfortable — you need a Whole-Home Dehumidifier.


How Does It Work?

Installed as part of your home's heating and cooling system, central dehumidifiers pull air from every room in your home through the return ducts. It removes the moisture and then sends dry air back throughout your home. It works in conjunction with your air conditioner to efficiently balance the humidity levels in your home, but can also work independently on days when you don't need the air conditioner.


Why Do I Need a Whole-House Dehumidifier?

 Have you ever experienced any of the following uncomfortable and/or unhealthy conditions:

•Do you have trouble sleeping at night due to clammy skin or stuffiness in the air?

•Have you ever reduced the temperature setting because you're uncomfortable with the stuffy feeling?

•Have your floors or other surfaces ever felt sticky or “sweaty”?

•Are you concerned with mold and mildew growth in your home?

•Do you have musty odors or smells in any area of your home?

•Do you have condensation on your water pipes?

•Have you seen wet stains on walls or ceilings?

Do you or a family member have allergies (over-moist air can encourage the growth of mold, bacteria, and dust mites—three commonly known household allergens).
Experiencing any of the above conditions can make sleeping and even daily activities miserable — plus some conditions can be hazardous to your family’s health or your home’s furnishings.

FACT: Did you know that dust mites (and their waste products) are one of the most common triggers for allergies and asthma? The Environmental Protection Agency advises keeping your home’s relative humidity between 30-50% to avoid dust mite infestation.

Molds are commonly found in outdoor air. However, any house can develop a mold problem given the right conditions. You might not see it growing on the walls, but it may still be present in your home. Molds require two factors to grow indoors: (1) free moisture that can occur in the form of relative humidity above 50 percent, leakage from pipes or foundations, or any ongoing source of water, and (2) something to grow on.”

“There is no practical way to eliminate all molds indoors; the way to control indoor mold growth is to control moisture."
