Do You Need a Whole-House Dehumidifier in Atlanta?

You wouldn’t dream of getting through an Atlanta summer without air conditioning. However, it takes more than beating the heat to keep your home comfortable. High indoor humidity can sabotage your comfort even when your AC is cooling to the desired temperature.

While your AC does remove some moisture from the air, it may not be enough given Atlanta’s humid climate.

The problem with high indoor humidity

According to the EPA, the ideal humidity level for a home in Atlanta during the summer is between 40 and 50 percent. At higher levels, the excess moisture can cause several problems.

  • Poor Comfort. High humidity makes your home feel damp and smell musty. It also impedes your ability to perspire, which is your body’s way of cooling off.
  • Overuse of AC. When excessive humidity compromises indoor comfort, many people crank up the AC. This does little to correct the moisture problem while unnecessarily raising electric bills.
  • Aggravation of Health Conditions. Mold, mildew, bacteria, and dust mites thrive in moist conditions, which poses health risks for anyone with allergies, asthma, and other respiratory illnesses.
  • Damage to Property. Prolonged excessive humidity can lead to mold and mildew growing on walls and ceilings, as well as bedding and furniture.

Signs of high humidity in your home

It is possible to measure the humidity level in your home. Some smart thermostats have this capability. You can also purchase a device called a hygrometer at most hardware stores. However, the signs of a humidity problem are often noticeable without needing to know a precise measurement.  

  • You notice wet spots on walls or ceilings that are not due to a leak.
  • Windows in rooms other than the bathroom and kitchen fog up.
  • Condensate – or little drops of water – forms on pipes.
  • You have a mold or mildew problem in rooms that do not have plumbing.
  • You keep lowering the thermostat in the summer (or raising it in the winter) in an effort to make your home more comfortable.

The benefits of a whole-house dehumidifier

A whole-house dehumidifier draws the humid air from every room in your home through the ductwork. After removing the moisture, it sends the dry air back to be circulated through the entire house. The benefits of a whole-house dehumidifier, when properly sized and installed, include:

  • Better Humidity Control. Compared with room dehumidifiers, a whole-house dehumidifier, as its name implies, reduces moisture throughout the entire home, not just in certain rooms.
  • Better Energy Efficiency. It uses less electricity than an air conditioner, making it both the more effective and more energy-efficient solution.
  • 4-Season Humidity Control. High indoor humidity can be a year-round problem for  many homes in Atlanta, even in the winter. While a whole-house dehumidifier integrates with your existing heating and cooling system, it can be used anytime, regardless of whether you’re running your AC or heater.
