Can I Safely Power Wash My AC Unit?

AC Maintenance in Cave Creek, AZ

When fall rolls around, and it’s time to clear the leaves and debris away from your AC unit, you may be tempted to use a pressure washer. However, these power tools can cause irreparable damage to your AC unit. They’re better suited to cleaning concrete or your home’s siding. Here’s why you should never use a pressure washer on your air conditioner.

Dangers of Power Washing

A pressure washer uses an incredible amount of pressure to remove grime. This force is measured in pounds per square inch (PSI). Your AC unit’s soft metal exterior can’t stand up to this amount of water pressure. Even a small battery-operated power tool is often too much for your air conditioner’s delicate coils and fins. Some of these tools are so powerful that they can put holes straight through your unit, causing expensive damage that requires professional repair services.

Rather than risking a whole system breakdown, the best way to clean your unit is with a rag or soft-bristle broom. The top of your unit can be removed, allowing you to sweep or wipe away any buildup inside. Avoid getting any wiring or the motor itself wet. Seasonally cleaning your AC unit gives you the chance to check for damage and rodent nests. If you’re nervous about taking apart your AC unit by yourself, you can always call in an HVAC technician. An expert will give you advice on how to best care for your air conditioner and prolong its useful lifespan.
