What causes buildup on AC coils?

Dirt, dust, and trash will cause build-up on exterior and interior coils. You can’t prevent this type of build-up on your coils. It becomes inevitable with time.

Cleaning Air Conditioner Coils Yourself…Or Not

You can clean the surface with a brush, to remove any surface debris yourself. If you are having issues from your unit and see ice or ice buildup with dirt, you may need a thorough chemical clean of your coils from a certified HVAC technician.

Chemically cleaning AC coils can be routinely necessary and is part of our yearly ESA maintenance program. Our ESA program is a great way to save dollars on your power bill and ensure the longevity of your HVAC unit. Everyone schedules regular maintenance and checkups for their vehicles, why not your Air Conditioner?

Causes of Debris Buildup that you can Prevent Yourself

Yard debris like grass, leaves, and weeds can get into your exterior coils and cause major buildup issues. Effectively keeping the area around your HVAC unit clean, and free from yard debris, is important.

In the Fall, when leaves start to fall, the wind will blow leaves around and start breaking them down into smaller pieces. If you don’t rake your leaves regularly, these smaller pieces of leaves can stick to your coils adding to the buildup on your exterior coils.

Plants, Bushes and Walls, Oh My…

Other common issues involve bushes and plants planted to hide the outside unit. Although plants are much more attractive for curb appeal, having plants close to your unit allows pollen and leaves to easily create additional buildup.

There needs to be a good few feet of space available around your outside air conditioning unit to allow it to work properly. Surrounding the unit with a wall or plants can cause restrictions on air flow. That, in turn, will cause problems with how your home is properly air conditioned and potentially increase your power bill.
