How Humidity Effects HVAC Performance

Humidity levels can be a factor in home comfort and HVAC performance. Your AC removes excess humidity from the air, which can take a toll on the equipment and affect its efficiency, especially now that we're into the warmer months. Here are some humidity related issues and solutions:

Humidity & AC

If your AC isn't removing the proper amount of heat and moisture, you may not achieve the comfort level you desire regardless of the thermostat setting. If you have an older, inefficient, or incorrectly sized system, it may not be able to keep up and your home will feel warmer than it actually is. This adds wear and tear and results in high utility bills.

Sings that you have excess moisture in the air:

  • The air feels moist

  • Damp or musty smell

  • Foggy windows

Dehumidification Strategy

Have a plan before the summer begins! The ideal humidity level in the summer is below 60%. The most efficient way to manage your home's moisture is to have an HVAC professional install a dehumidifier. It will work with your system to pull excess water from the air before it travels through the ducts and into your home
