Coil & Air Handler Cleaning

The evaporator coil and air handler are the heart of your HVAC system, and they're also the most likely place for mold, dust, and biological growth to develop. Because the evaporator coil runs cold and wet during cooling season, it's a natural collection point for airborne dust, mold spores, and microbial films that degrade air quality and reduce the system's ability to transfer heat efficiently. Ross Air Duct Cleaning provides careful coil and air handler cabinet cleaning using no-rinse coil cleaner, soft-bristle brushes, and a low-pressure rinse to restore coil surface area and eliminate biological buildup.

A dirty evaporator coil can reduce your system's cooling capacity by 20% or more, forcing it to run longer cycles and driving up your San Antonio summer energy bills. Our technicians access the air handler cabinet, carefully apply coil cleaning solution to the evaporator fins, and clear the condensate drain pan and drain line of any algae or sludge that could cause water overflow and ceiling or floor damage.

We also wipe down the interior walls of the air handler cabinet and inspect the blower wheel for dust accumulation that reduces airflow. This service is an excellent complement to a full duct cleaning and is strongly recommended for any San Antonio home that has not had coil maintenance in the past two to three years or that shows signs of reduced cooling performance.
