Evaluating Your Need For A Whole-House Dehumidifier

Last updated 1 year ago

By Greg, Pacific Aire Comfort Advisor, 

The purpose of a whole-house dehumidifier is to remove excess moisture from the air in the summer. Air conditioners have a dehumidifying function, but sometimes it isn’t enough to prevent that clammy feeling caused by overly humid, cold air. 

Here’s a quick look at how to evaluate your need for a whole-house dehumidifier:

  • Is the relative humidity too high? To find out, purchase an inexpensive hygrometer to measure the relative humidity in various rooms around your home. If the device shows readings of 50 percent or higher, you could benefit from a whole-house dehumidifier to remove excess moisture and help you feel more comfortable in the summer, along with avoiding mold problems.
  • Do you feel an uncomfortable clamminess in your home? When the air conditioner runs, it cools the air, but if it isn’t being dehumidified enough, the air will feel uncomfortably damp. The addition of a whole-house dehumidifier can help improve comfort all summer long.
  • Are you looking to save on energy costs? While dehumidifiers require some amount of electricity to operate, the resulting drier air will feel cooler at higher temperatures. This drier air will allow you to set your thermostat 2 or 3 degrees higher -- without feeling less comfortable. Therefore, a whole-house dehumidifier can help save on cooling costs, too.
  • Do you open windows in the spring and fall to enjoy natural ventilation? If so, it’s likely that the upper floors in your home have relative humidity levels that are higher than 50 percent. This can cause problems over time if the accumulated moisture becomes trapped in the winter when your home is closed up. To prevent this, you should plan to run a whole-house dehumidifier any time your windows are closed in the spring, summer and fall so moisture can’t accumulate.
  • Does your home lack air conditioning? You can stay cooler and avoid moisture problems in the summer by installing a whole-house dehumidifier. This can be particularly beneficial in the basement, where relatively humidity levels tend to be the highest.
