The Best Evaporator Coil Cleaning in 2021

Cleaning A/C evaporator coils

It is essential to check and clean evaporator coils as necessary. If the coils quickly collect debris and dust, monthly cleaning might be required. Otherwise, they may need to be cleaned every three months during the cold seasons or one per year for regular scheduled preventive maintenance.

Get access to clean your A/C evaporator coils.

There should be an access panel on your indoor air-handling unit that you can remove to access the evaporator coil. If necessary, refer to the A/C owner’s handbook to find the evaporator coil and entrance.

Turn off the air conditioner at the thermostat.

To loosen the panel, take out the screws or ties.
Set aside the screws and panels, so you do not lose them.

Use compressed air to clean your A/C evaporator coils:

You can often remove lighter buildups of dirt and other materials by applying compressed air in order to blow them off of your evaporator coil.

Run the compressor air across the coil in the opposite direction of regular airflow, from the cleaner over to the dirtier side.

For materials that are more stubborn, but the air nose near the bottom of the debris. If you are using high-pressure air, either direct it through the fins or at a 90-degree angle. That will prevent the fins from becoming damaged. Make sure constant airflow is maintained over the coil. That will remove buildup without having to force it into the fins and further and making it harder to remove. Avoid blasting debris, dirt, and dust into your home’s living areas and ductwork system. Wear eye protection to keep debris away from your eyes. Use a commercial vacuum cleaner from a store if necessary to remove stubborn materials.

Use a brush to clean the A/C evaporator coils.

Cleaning with a brush can be a very beneficial method for removing minor dirt accumulations on evaporator coils. When you use a brush to clean, it allows you to use substances or liquids. You will have more control over the force you apply to the fins and reels.

Use your brush on the coils to clean away dirt piles.
Scrub with your brush to free hard-to-remove debris.
Avoid using hard-bristle brushes or cable brushes since they can damage the fins.

Use industrial cleaners to clean your A/C evaporator coils:

There are many major commercial cleaner brands that are available to clean evaporator coils. One of the most effective is a foaming type that can drain the drainage system of the unit. Give All Time Air Conditioning a call for information on the best cleaner for your individual situation.

Use water and a mild detergent to clean your A/C evaporator coils.

Instead of using a commercial cleaner, warm water and mild soap can be used instead to clean your coils. Combine a simple cleanser and hot water in a garden sprayer, grip sprayer, or spray bottle. Apply the detergent liquid and water to your evaporator coils. Allow the solution to soak for a few seconds to free the debris. If necessary, reapply the solution. Use a brush or soft cloth to wipe away any loose materials.

Use heavy-duty cleaning to clean your A/C evaporator coils:

Really dirty evaporator coils might need to have strong chemicals applied or heavy-duty cleaning methods, including such equipment as a steam cleaner or force washer. You might need to make some changes to your A/C system when using this method, such as removing the coil, cutting and then reattaching the refrigerant coils, or replacing the refrigerant channels vacuum and then refilling the system’s refrigerant.

If you have heavily soiled A/C evaporator coils or they are dirty enough to where it can seriously impact the functioning of your air conditioner, you should contact a local HVAC contractor and schedule professional maintenance and cleaning appointment. All Time Air Conditioning will assess the job accurately and restore the functioning of your cooling system and clean the evaporator col without damaging the fins, reels, or any other system components.
