Humidity Is Bad News in Summer for More Than One Reason


Although we’re used to thinking of humidity as an all-around negative, that’s not true. In fact, during a cool winter day, a rise in humidity takes the edge off the colder temperatures and makes it easier to stay warm. Humidity also keeps skin moisturized and prevents dried-out sinuses.

But these are all winter issues, and we’re now at the end of spring, with temperatures and humidity on the rise. Nobody likes high humidity in the summer! 

You can’t do much about high humidity levels outdoors, but there are solutions to help inside your home. Central AC repairs in Conyers, GA from our technicians can help an air conditioner get better control over humid conditions, and we also offer installation of powerful whole-house dehumidifiers that allow you to balance humidity at the perfect spot between too humid and too dry. 

Why Defeating Summer Humidity Is Important

High humidity (above 60% relative humidity) creates multiple problems in a house. Getting a handle on humidity levels helps you overcome several different issues:

  • Discomfort: This is what you probably think of first when you hear the words high humidity. High levels of moisture in the air don’t make the air hotter, but they do make it harder for the human body to release heat and therefore causes people to feel hotter. For example, if the relative humidity is 75% (which is the average during August in Atlanta), 85°F feels like 95°F, and that’s a huge difference. But if you have indoor humidity lowered to 40%, that 85°F will feel like … 85°F. 
  • Energy savings: Going back to that 75% relative humidity scenario, think of how much more you have to run your AC to overcome a feeling of 95°F compared to 85°F. When humidity is balanced, you can cut down significantly on how long your air conditioning system must stay on, and that will cut down on your electric bills. 
  • Mold and mildew: Humid conditions allow mold and mildew to thrive. Both are unpleasant to see and to smell, and some types of mold release harmful spores that can affect the health of people in a home with asthma and allergies. 
  • Water damage: Humidity is extremely damaging to wooden surfaces, and it’s a type of damage that is difficult to remediate. Humidity is also harmful to paint and wallpaper. Balanced humidity will help parts of your home last longer, and you won’t have to worry about rotting furniture and ruined wooden floors. 

Let Us Help Control Humidity in Your Home

As we mentioned above, a broken AC can lead to humidity getting out of control. An air conditioner isn’t a dehumidifier, but it does remove some moisture from the air as it runs, so that if when an AC breaks, an increase in humidity is often one of the first signs something is wrong. 

The best way to enjoy balanced humidity is with a whole-house dehumidifier. Our technicians can install this device into the ductwork, where it removes moisture from the air without cooling it. You can make adjustments to the humidity levels from the home’s thermostat to find the right balance (we recommend 40–45% relative humidity as the golden zone). Reach out to us today to learn more about installing a whole-house dehumidifier.
