The evaporator coil inside your air handler is the heart of your home's cooling system, and it's one of the most neglected components when it comes to routine maintenance. Over months and years of operation, a thin layer of dust, pollen, mold, and biological matter coats the coil's fins and surfaces, acting as insulation that dramatically reduces the coil's ability to absorb heat from your home's air. White Brothers San Antonio Air Duct Cleaning uses no-rinse coil cleaning foams and low-pressure spray washing to safely break down and flush away buildup without bending delicate aluminum fins or damaging refrigerant lines.
A dirty evaporator coil forces your AC system to run longer cycles trying to reach your thermostat set point, increasing energy consumption and putting extra wear on the compressor — the most expensive component in your system to replace. In severe cases, heavy coil fouling can lead to ice formation on the coil, refrigerant pressure problems, and complete system shutdown during San Antonio's hottest summer months when you need cooling most.
Our technicians access the coil through the air handler cabinet, apply appropriate cleaning agents based on the level of buildup, and inspect the drain pan and condensate drain line for biological growth and blockages while the cabinet is open. Evaporator coil cleaning is most effective when combined with air duct cleaning and is recommended annually for San Antonio homes given the region's long cooling seasons and high pollen loads.
