Why Your Florida Home Feels Humid Even When the AC Is Running 

Homeowners in the area often ask the same question come summer: “Why does my house feel humid with the AC running in Altamonte Springs & central Florida?” The cooling system might be able to drop the temperature, but the indoor air still feels warm and clammy.


Air conditioners are actually designed to help with humidity. The only issue is that they often can’t accomplish it if the unit is struggling to keep up.


So Why Does My House Feel Humid With the AC Running in Central Florida?

Your HVAC equipment likely has one of the more common mechanical issues if humidity is an ongoing problem. But it’s not always that simple.


Oversized AC units often have way too much power for spaces they aren’t properly sized for. Systems with too much power cool down a home incredibly fast and then shut off immediately. Because these cycles run so quickly, the unit doesn’t run long enough to effectively remove water vapor from the air.


Frozen evaporator coils are one clear component-related issue. You might have ice stuck to your coils if you’re running your unit with a dirty filter or if it has lower levels of refrigerant.


Steps for Lowering Indoor Humidity

Start by troubleshooting a few things on your own to see if that helps:

  • Check your air filter every 30 days and replace as needed
  • Make sure your thermostat fan is set to “auto” and not constantly “on”
  • Keep dirt and debris away from your AC’s outside unit
  • Use dehumidifiers to target the rooms with the most moisture


If none of these are doing enough to manage humidity in your home, you can upgrade your setup for a more permanent fix. This includes installing a whole-home dehumidifier directly into your ducts. This will help address the humidity in every room and prevent your AC from working too hard.


However, the most beneficial professional solution is to schedule regular HVAC tune-ups with a technician. Doing so can help you reduce your indoor humidity and lower your energy bills while also improving the comfort of your home.
