Most homeowners understand that regular HVAC maintenance is critical to keeping their air conditioners running smoothly and efficiently. Some wonder how much of this maintenance they can perform themselves. A frequently asked question is whether a homeowner should power wash an air conditioner unit.

Can You Power Wash Your AC Unit?

The short answer is no. It’s never a good idea to pressure wash or power wash an air conditioning unit. For one thing, air conditioner units are typically made of aluminum, which is considered a “soft” metal that may not be able to handle the pounds per square inch (PSI) of pressured water that a power washer puts out.

Power washing an AC unit can damage the coils. In some cases, the intense pressure has even blown holes right through the tubing inside the unit. Damaged coils, fins, and tubing on an air conditioner can make for expensive repairs. In many cases, it will be cheaper to replace the AC unit than to repair the damage done by the pressure washer.

You may be wondering if a garden hose could be used to wash an AC unit since it puts out far less pressure than even the smallest power washer. The short answer is “yes, but…” Yes, a garden hose can be used to lightly rinse material like dust or grass clippings off the exterior of the AC unit, but the hose won’t provide enough power to clear the coils of debris.
