How To Wash Your Air Conditioner

While the summer may be wrapping up soon, the monthly forecast still shows many more hot, humid days in store for our area. Will your air conditioner be performing efficiently? Does it have what it takes to keep you comfortable through this last stretch of heat?

What you may not know, is that over time, dirt and debris can collect on and clog the outdoor condenser coil. Doing so can cause a number of issues, some of which include overworking the system, running up your electric bill, warm air coming out of the vents, and air conditioner breakdown altogether.

One precaution you can take to help yield better operation and efficiency of your system is to consider washing your A/C.

So, what is the correct way to wash an air conditioner? Follow these steps...

Turn OFF The Power To The A/C

Set the cooling mode to OFF on your thermostat or turn off the power source at the indoor breaker box or outdoor fuse box.

Remove Large Debris From The Unit

Locate any collection of leaves, grass clippings, branches, weeds, etc. that are removable by hand and pull and brush them off the outdoor unit.

Spray Down The Air Conditioner

Find a hose with adjustable pressure. Use a low-medium pressure and, starting from top to bottom, gently rinse the coil. Try spraying at different angles to remove anything that may be caught in the coil. NOTE: DO NOT use a power washer or high-pressure hose attachment as the high water pressure can bend/damage the delicate fins on the coil.

Turn The A/C Back ON

The air conditioner doesn't need to be completely dry; go ahead and turn it back on shortly after rinsing.


Now that you've done your part to clean off the cooling system, you should also check your furnace filter to see if it is time to clean or change that as well. Doing these simple maintenance tasks can help allow your air conditioner to continue to keep you comfortable throughout the rest of the season.
