The Effect of Humidity on Air Conditioners


An air conditioner works to cool your home and control humidity. Higher humidity increases your unit's workload, therefore decreasing its efficiency.

Higher Humidity

  • Higher humidity causes moisture to form inside your air conditioner. When water vapor condenses, it generates heat in the process and adds to the temperature of the air.

Ways You Add Humidity

  • What you do in your home, like cooking and drying clothes, adds to humidity already in the air and makes your air conditioner less efficient. Also, every time you open your doors and windows, you let in additional moisture.

Power Consumption

  • Decreased efficiency of your air conditioner means higher power consumption and higher electric bills.

Easy Ways to Boost Efficiency

  • Help out your air conditioner by controlling temperature and humidity inside your home. Cover pots and pans when cooking, do not line-dry your clothes indoors, keep doors and windows closed during the day and keep your air conditioner's coils clean.

Other Ways of Boosting Efficiency

  • To help your air conditioner work better, vent your dryer to the outside, not inside, install a thermostat you can program for power-saving settings and install ceiling fans to better circulate cool air.
