What Is That Musty Smell Coming from My AC in St. Cloud, FL?

Failing to maintain your HVAC system can translate into multiple problems, such as musty odors filling the inside of your home. If you notice musty smells coming from the AC in your St. Cloud, FL, home, read on to learn how to address the possible causes.

Frozen Evaporator Coils

Air conditioners work by taking heat from inside the home and moving it outside. The air moving over the cold coils gets cooled and recirculated through your home’s return vents. This reduces indoor humidity and moisture; however, if the AC has a dirty filter, this will diminish airflow, therefore increasing humidity.

The increase in humidity from the dirty air filter causes water droplets to form on the evaporator coils. If the water gets cold enough, it freezes the coils. By regularly replacing the air conditioning filter, you can keep the air flowing freely and lessen the musty odor.

Blocked Condensate Line

In most cases, a section of PVC pipe serves as the condensate line for an air conditioning unit. Water from the air conditioner’s drip pan flows into this pipe, which ends adjacent to the outside condenser unit.

Mold and mildew are almost inevitable because of the high levels of moisture in the condensate line. If this occurs, you may notice a musty odor in the house. The easiest way to address this issue is by cleaning the clogged or blocked condensate line.
