Humidity Control for your Home in the Summer

Learn why humidity control is important during the cooling season.

The Basics and Benefits of Removing Humidity from your Home

When it comes to cooling your home in some regions of the country, humidity control is as big of a problem as high temperatures. Unlike the arid Southwest, the Southeast and parts of the Midwest have very high humidity in the summer months and this can result in higher than necessary energy bills if you aren’t careful.

Humidity is behind the “heat index” you hear on the weather report and drives the “feels like” temperatures that are usually several degrees hotter than the actual temperature. Selecting and properly sizing your air conditioning equipment to deal with humidity is a little more difficult than just getting something that keeps you cool on the hottest days.

The Basics of Removing Humidity

Most central air conditioning systems are capable of removing humidity from the air in your home. Window units or ductless systems do not generally move enough air through the system to remove the humidity evenly from your entire home. While most central AC systems will work, effectively controlling your humidity so you’re comfortable day and night is best achieved with a high efficiency system.


  • To remove humidity, an air conditioner has to be running. Basic, minimum 13 SEER systems typically run in either “on” or “off” mode. High efficiency systems (16 SEER and up) usually provide variable speed capacity which can run longer on lower power, giving the system more time to remove humidity.
  • High efficiency systems are able to control the temperature more precisely, eliminating noticeable cold or hot swings and not allowing humidity to build up in the air.
  • Because the air is constantly being conditioned with a high efficiency system, there is much less chance of stagnant humid air causing mold in the walls or attic.

Additional Benefits

In addition to the added comfort you’ll feel with a high efficiency system capable of removing humidity, they also run much more quietly, which can be a benefit at night when you’re trying to sleep. Because they run on variable speed, high efficiency systems are also much more energy efficient, which translates to money saved every month on the energy bill.

The Bottom Line

If you live in an area of the country that is naturally humid, talk to your contractor about humidity control and higher efficiency systems that can provide you with a comfortable environment, not just cold air.

  1. Hi..I live in Rhode Island in a single family home. We have a forced air heating unit (Trane Gas Furnace) and I want to add central AC to it. The duct system is old and its single zone. Do you think it will make sense to add a high SEER rating central AC system that will take care of the humidity in the house? Given there are old ducts, I was given to understand by a contractor that the first floor cooling would be find but second floor might not be that great. I can live with that as long as the humidity levels in the whole house can be managed with the central AC. Your suggestions?

  2. You have explanation very important things on humidity control that was unknown to me. I did not know the information before. I think everyone should be know about that informative article. I also using ac in my house . But sometimes faced ac overheating problem and also got the solution through browsing site. Because I also got the solution.
