Could Washing AC Units Cause Damage?

Air conditioning units sit outside your home. Because of this, they can get pretty dirty, covered with mud, leaves, and other debris. It’s tempting to wash the unit, but is it a good idea? Could washing the AC cause damage? Let’s look.

DIY Washing Your AC

The good news is that you can wash your outdoor AC unit. There are some things to keep in mind, however, to prevent damage.

  • Don’t use a power washer! A power washer might seem like a good option for outdoor cleaning, but it’s too much pressure for air conditioning equipment. The high power could damage the coils. Save the pressure washer for the deck, the driveway, and the car.
  • Before washing, be sure to remove plants, vines, weeds, and debris from around the equipment.
  • Disconnect the power before opening the casing to access the components.
  • Carefully clean the fan blades with warm water and a gentle detergent.
  • Inspect the coil and motor for dirt and grime.
  • Rinse with a spray water bottle or with a hose turned on to a very low flow.

Hiring a Professional

Part of HVAC maintenance includes cleaning the heating and cooling equipment. If you’re worried about the dirt on your outdoor AC unit, it’s best to call in a professional. Not only can they show you how to clean the outside of the unit safely, but they can also inspect and clean the inside without risking damage to any of the parts.

Before taking AC cleaning into your own hands, put the cleaning in the hands of the experts. Contact your local McCall’s Supply, Inc. dealer to schedule your next AC service.
