How Do I Clean My A/C Condenser?

When dust, bugs, feathers, and other debris collect on the face of condenser fins and tubes, they form a thermal barrier that can prevent the efficient transfer of heat. A fin comb, air hose and nozzle, soap and water—all can be used to keep the condenser clean. Avoid using a high-pressure hose, which can damage fins and disrupt the airflow across the condenser.
