Did you know the average AC unit can last up to 25 years? You can lengthen the lifespan of your unit by cleaning it.

You see, when dust accumulates on condenser coils, it can force HVAC units to work harder. Over time, this will lead to costly repairs and machine malfunction. It’s also not too energy-efficient.

Are you not sure how to clean an outside AC unit? We can guide you through the process. Continue reading to learn more. 

How Often Should You Clean Your Unit?

To keep your AC unit running at peak efficiency, you should give it a deep clean once a year. The best time to scrub it down is at the end of spring, right before the hot weather hits. 

During the fall, go outside periodically to clear debris away from the machine. The dead leaves and twigs can clog an AC unit. 

Tools You’ll Need

Before you start cleaning, you’ll need to gather the proper tools. Gloves, goggles, and a long-sleeved shirt will keep you safe while you work. 

You’ll also need a screwdriver, a garden hose with a spray attachment, a soft-bristled brush, a shop vacuum, and an AC coil cleanser

Prepare the Unit

The next step of AC maintenance is to prepare the unit. Remove any large leaves and twigs. If there’s a tree that’s growing too close to the unit, trim the branches. 

Use your thermostat to turn off the power to your unit. You’ll also need to unplug the outdoor unit, and flip the breaker off. If you fail to shut off all power sources, it could result in your injury. 

Remove the Cover

Now that you’ve prepared the unit, you can remove the top cover. Be sure to follow the manufacturer’s instructions when you do so. 

Once the cover is off, you’ll have access to every part of the unit that needs to be cleaned. Grab your brush and scrub the dirt off the condenser coils. You can use the shop vacuum to suck up any leaves or other large pieces of debris. 

Spray the Unit Down

Apply the AC condenser cleaner to the coils and allow it to sit for about ten minutes. Rinse the unit with your garden hose. You may need to use the brush to get rid of any stubborn dirt.

Replace the Top

Once you’ve finished cleaning, place the top back on and return power to the unit. Don’t forget to plug it back in and turn it on at the thermostat. You should now have noticeably cooler air flowing through your home.
