Cleaning AC Coils: The proper Way 2022

Sep 7

Accessing your AC coils is the first step to cleaning them. You will find the evaporator coils in your indoor handling unit behind a removable access panel. Before you do anything, turn off the thermostat to prevent the air conditioner from turning on. To be safe, you may need to turn off the circuit breaker. Next, take out the fasteners or screws and loosen the panel. Make sure the panel is not lost.

Next, you can clean your AC evaporator coils using one of these techniques:

1. Compressed air. 

You can often remove dirt from your coils if there isn’t much of it. The compressed air should be directed opposite to the normal airflow. You should also ensure that the airflow is consistent across the coil. Wear eye protection, and use a shop vacuum to remove any dirt or debris.

2. Using a brush. 

This is an excellent way to remove light dirt from the coils. It also allows you to control the pressure and the areas being cleaned. This method involves using a brush to clean the coils. Scrubbing is possible for more stubborn dirt. Avoid using wire brushes or bristles, as they can damage the fins.

3. Use commercial cleaners. 

Many cleaners can be used to clean your evaporator coils. Follow the instructions provided by your cleaner after you have chosen the brand that you prefer. Let the cleaner sit for a while and let the foam and debris disappear. Repeat the process as directed.

4. Use mild detergents and clean water. 

A mild detergent mixed with water is an excellent alternative to a commercial cleaner. Use a spray bottle or a garden sprayer to mix a mild detergent with warm water. Spray the solution on the evaporator coils. Allow it to sit for a while to absorb the dirt and debris. Use a soft cloth or brush to remove any loose material and apply the solution as necessary.

5. Heavy-duty cleaning. 

Heavy-duty cleaning may be necessary if your evaporator coils have become soiled. This could mean you will need to do more than standard cleaning. You may have to remove the coil and cut the refrigerant lines. Then reassemble the unit. You should consult with AC services mesa az if this is the case. They will be able to assess the job and have the right equipment, training, and supplies to clean and restore your AC system to its normal state without exposing it to any potential damage.
