How to Clean Your AC Condenser

Your air conditioner has two major components, the evaporator inside and the condenser outside. The function of the condenser is largely dependent on keeping the unit clean. It is a necessary part of maintenance, so here we’ll give you some basic tips on how to clean your AC condenser.


The first step in cleaning the condenser unit is to shut off the power. A box near the condenser contains the shut of switch. This is an important first step in the cleaning process, and it is an absolute must when it comes to safety.

Outside Debris

Use a broom, rake, and hose to remove any debris that may have built up on top of or around the unit. Using a screwdriver, go around the unit, take out the screws, and remove the outer metal casing. Spray down the casing to remove any dirt.

Inside Dirt

Unless your air conditioner has excessive build-up of dirt, a simple spray-down with water should do the trick. However, cleaners made specifically for coils are available. Follow label instructions. While using the hose to spray down any part of the unit, use care regarding pressure. Too much water pressure can bend and damage fins and other parts.

Next, reassemble the unit and turn the power back on. When you are ready to use your air conditioner, the cleaning you’ve just done will greatly improve the efficiency of your unit.

The above steps are for a basic cleaning of the condenser. If you would like further information or would like to schedule a more thorough maintenance, please contact us.
