How to Clean an Outdoor Air Conditioner

Updated: Oct 13, 2022

It's no secret that nearly everyone loves the feeling of walking into a chilly, air-conditioned home on a hot day. But, to ensure your exterior air conditioning unit continues to pump out cool air all summer long, you must give it care and maintenance - including a good cleaning.

Cleaning your outdoor air conditioner unit may seem daunting, but we promise it's not as complicated as you think! You can have your AC unit looking and running like new in just a few simple steps.

Here's how to clean an outside air conditioner unit without calling in a professional.

First, you'll want to be sure that you've cut electrical power to the unit before beginning any cleaning. The safest way to power down the unit is to flip the circuit breaker that controls it.

Once you've done that, it's time to remove any debris - such as leaves, dirt, or twigs - accumulated around the unit's base. Clearing away blockages ensures that your AC has proper inflow and outtake, so it works efficiently.

Next, you'll want to clean the fins on your air conditioner. These metal pieces help dissipate heat; over time, they can become bent or clogged with debris. Gently straighten any contorted fins with a fin comb or knife. Afterward, use a garden hose to spray off any dirt or debris.

Once the fins are clean, it's time to move on to the coils. These are behind the removable panel on the side of your unit. First, use a soft brush - such as an old toothbrush - to dislodge any dirt or debris clinging to the coils.

Then, create a cleaning solution consisting of one part vinegar and one part water. Use it to clean the coils. Rinse the coils thoroughly afterward with clean water to remove any residual vinegar.

The last step in cleaning your outdoor air conditioner unit is to replace the filter. A clean filter will help your AC run more efficiently and prevent dirt and debris from entering your home.

Maintenance Keeps Your Unit Running Optimally

The average expected air conditioner lifespan is around ten years, but with proper maintenance, yours can last much longer. In addition to regular cleanings, be sure to have your AC unit serviced by a professional once a year.
