Ideally, air conditioning maintenance should be performed twice a year, though once is sufficient for some systems. Between visits, the condenser coils can be cleaned by removing large debris and rinsing the coils with a hose, after shutting the power off. The Importance of Clean A/C Coils It is estimated that dirty evaporator and condenser coils can increase the energy usage of your air conditioning system by over 30 percent. Additionally, reduced heat transfer efficiency can cause other problems, such as poor cooling performance, frozen evaporator coils and compressor overheating. How to Prevent Dirty Coils To keep the evaporator coils clean, it is important to check the air filter at least once a month and replace it as necessary. A dirty air filter can allow dust and debris to accumulate on the evaporator instead of the air filter, and it can also reduce airflow in the system, leading to other problems. To keep the condenser coils clean, keep an area of two feet around the condenser unit clean of vegetation and debris, including trash, tall grass, plants and overhanging trees or bushes. Remove large debris as it falls into the condenser coils, and when mowing, be sure to discharge clippings away from the condenser. Cleaning the Coils The fins on the evaporator and condenser coils are extremely delicate and can be bent with very little force. It is best to leave the majority of the cleaning to an air conditioning contractor, who will clean the coils during a routine maintenance visit. Ideally, air conditioning maintenance should be performed twice a year, though once is sufficient for some systems. Between visits, the condenser coils can be cleaned by removing large debris and rinsing the coils with a hose, after shutting the power off. The evaporator is often difficult to access, and should be cleaned professionally.
