How High Humidity Affects Your HVAC System


Summer doesn't just bring high temperatures to Florida - it also brings high levels of humidity. More water vapor is in the air - not just outside but also inside your home. Air conditioners help combat humidity by using an evaporator coil to condense hot, moist air so that it cools down and cannot hold as much water vapor. If your HVAC system is old or broken, it may not be removing moisture from the air properly.

Here are some signs your indoor humidity is too high:

  • condensation on windows
  • moist or clammy air
  • a musty odor
  • mold and wet stains on walls and ceilings
  • increased amount of bugs

Upgrading your HVAC system can mean you'll have a better defense against high humidity. This dehumidification feature will help your new system do a better job of keeping your house cool and comfortable - not to mention save you money.

Insulating ductwork and using exhaust fans in bathrooms and the kitchen can also help.

If your HVAC system's dehumidifying process is failing, it's important to call a professional to check it. David Gray Heating & Air technicians can take care of your dehumidifying needs - from repairing and replacing humidistats and hygrometers in air conditioners to consulting with you about which size AC unit is best for your home.
