Evaporator Coil Cleaning
Clean the coil. Restore the cooling. Improve the air you breathe.
The evaporator coil sits above your furnace or air handler and removes heat and humidity from the air. When it's coated with dust, biofilm, or mold, your AC loses cooling capacity, your bills climb, and your indoor air quality drops. GERARDO HVAC LLC cleans evaporator coils throughout Fort Dodge, Webster City, Humboldt, and Eagle Grove, Iowa.
Signs You Need Evaporator Coil Cleaning
- AC runs constantly but rooms never get cool enough
- Ice forming on the coil or refrigerant lines
- Musty smell when the AC runs
- Higher than normal humidity indoors
- Visible dirt or biofilm on the coil fins
- Frequent need to clear the condensate drain
How I Approach Evaporator Coil Cleaning
I access the coil through the cabinet, protect the surrounding components, apply an evaporator-safe foaming cleaner, allow it to break down dirt and biofilm, then rinse and let it drain properly through the condensate line. I also clear the drain line and float switch and verify post-clean superheat.

Evaporator Coil Cleaning — FAQs
How often should the evaporator coil be cleaned?
Every 2-3 years for most homes, more often in dusty homes, homes with pets, or homes with low-MERV filters.
Will cleaning the evaporator coil get rid of musty smells?
Yes, usually — most musty AC smells come from biofilm on the coil or in the drain pan.
Can a dirty coil cause ice buildup?
Absolutely. Restricted airflow over a dirty coil drops the coil temperature below freezing.
Will a better filter prevent this?
Yes — a quality pleated filter changed on schedule dramatically slows coil fouling.
