In this blog, you will get to know about the best ways to clean the evaporator coils properly. Let’s dive in!

Top Signs That Indicate the Need to Clean the Evaporator Coil

Wondering how to know if the evaporator coil requires cleaning? If yes, consider the prominent signs listed below.

  • A build-up of ice on the coil leading to a frozen evaporator coil
  • Increase in the operating pressure
  • Increase in the wear and tear of the system
  • Higher energy consumption
  • Reduction in the cooling capacity
  • Higher temperature.

Tips to Clean the Evaporator Coil

Take a look at the tips to effectively clean the evaporator coil of your HVAC system.

  • Use a Brush

One of the easiest and simplest ways of cleaning the evaporator coil is to use a brush. It is effective in getting rid of the small amounts of dirt on the coil. Using the brush, you can sweep away dirt from different areas of the coil. However, to avoid damage, make sure to use a soft brush.

  • Leverage Compressed Air

Compressed air is another effective way of cleaning the evaporator coil. However, it works well only if the dirt build-up is not that heavy. When using compressed air, make sure to direct it in the opposite direction of the normal airflow. Also, wear proper eye protection while using compressed air to clean the evaporator coil.

A point to note here is that the compressed air is powerful and can bend the fragile coil fins. So, it is important to keep the nozzle a minimum of two to three inches away from the surface of the evaporator coil.

  • Use Commercial Cleaners

In case the dust and dirt don’t go away with a brush or compressed air, you can make use of commercial cleaners. There are several cleaners available in the market. You can get the one that is readily available to you. Irrespective of the cleaner you have selected, make sure to follow the instructions carefully.

You can also leverage a mild detergent and water as an alternative. Spray the solution on the coil, wait for the dirt and debris to loosen, and wipe it using a soft cloth.


Following these tips can help in the effective cleaning of the evaporator coils. However, if your HVAC systems don’t operate efficiently even after cleaning, you can opt for carrier evaporator coil replacement. Are you in search of the best quality carrier coil replacement?
