The effects of humidity on HVAC Performance

As the heat and humidity levels continue to fluctuate, homeowners are cranking up their air conditioning units to keep up and maintain comfort inside of their homes. When it comes to comfort, though, humidity levels are a major factor to keep in mind when considering your HVAC performance. One of the main functions of your A/C system is to remove excess humidity from indoor air. This means that your HVAC unit has to work just as efficiently during the summer as it does during winter months.

Humidity and HVAC performance

If your HVAC system is working correctly, it should get rid of the right amount of heat and moisture from your home, creating the comfort levels you want. If you’re experiencing unexpected temperature changes or hot and cold spots, regardless of the temperature setting you’re using, your HVAC performance may be suffering. When the humidity is high, your A/C unit has to work harder to keep your house cool. If you have an older, inefficient HVAC unit or it’s the wrong size, it may not be able to keep up with how cool you want your home. You may end up feeling warmer because your HVAC performance is low and the air inside your home is holding extra moisture.

Poor HVAC performance can also cause your energy bills to skyrocket, if your system has to run longer and harder to provide you with the right temperature. This also wears down your HVAC unit.

It’s important to note that a larger A/C system isn’t always the answer to keeping your home cool. Your system should be sized by a professional HVAC technician. An expert from A-Abel can help you determine what size your home needs.

Signs of Humidity Within Your Home

If your home has a central air conditioning system but you’re not getting the results you want, you can assume that one of the main issues as to why is that there’s too much moisture in the air. Some signs of this are:

  • The air inside of your house feels moist
  • Damp/musty smells in areas of your home
  • Foggy windows


The best way to manage excessive moisture is have a professional install a dehumidifier to help with your HVAC performance.

The dehumidifier will work with your A/C unit to draw in moisture from the air before it gets sent throughout your home. A knowledgeable HVAC professional, like one from A-Abel, can help get you set up with a compatible dehumidifier for your HVAC system.
