Condenser and evaporator coil cleaning
Dirty coils make the compressor work harder, raise power bills and shorten equipment life. A tech cleans the outdoor condenser with coil cleaner and low-pressure rinse from the inside out, and cleans the indoor evaporator coil when it's accessible.

Outdoor coils collect whatever the local air carries: desert dust in the Southwest, pine pollen in the Southeast, cottonwood fluff in the Midwest and salt in coastal areas. All of it blocks airflow and raises operating pressure on the hottest days.
Indoor coils clog when filters are skipped or the wrong size. A clogged evaporator causes freezing, low airflow and condensate overflow.

FAQ
Coil Cleaning questions
How often should AC coils be cleaned?+
Once a year for the outdoor coil, usually in spring, and more often in dusty, coastal or high-pollen areas. The indoor coil needs cleaning less often if filters are changed regularly.
