How to Clean Your AC Condenser

Your air conditioner has two major components, the evaporator inside and the condenser outside.

The efficiency and effectiveness of the condenser is largely dependent on keeping the unit clean.

It is a necessary part of maintenance, so we’ll give you some basic tips on how to clean your AC condenser.

1. Power

The first step in cleaning the AC condenser unit is to shut off the power. A box near your AC condenser contains the shut of switch.

This is an important first step in the cleaning process, and it is obviously an absolute must when it comes to safety.

2. Outside Debris

Use a broom, rake, or hose to remove any outside debris that may have built up on top of or around the unit during the winter months it hasn’t been used.

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.

3. 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 AC coils are available. Follow label instructions for he best results.

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.

4. Putting it all back together

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, making your home cooler.
