Coil Assembly Cleaning

The coil assembly, or evaporator coil, is located inside the heat pump or air conditioner cabinet. All the air from the home flows across this coil to be cooled in the summer. When air conditioning, the indoor coil is damp, and attracts dirt and can harbor mold and other contaminants. A dirty indoor coil endangers your family’s health, wastes energy, and reduces the capacity of the cooling equipment. Dirty indoor coils are notorious for reducing the air flow through the equipment. For each 10% reduction in air flow, the efficiency of the equipment drops about 5%. Reduced air flow means less cooling and makes it difficult to maintain a house’s comfort in hot weather. The coil should be cleaned every few years depending on how often the system operates, the efficiency of the filter at trapping dirt, and the airtightness of the ductwork.
