Tasks that should be performed include system adjustment and testing, component replacements, minor repairs, air filter changes, and cleaning condenser coils and evaporator.

The Basics Of Cleaning A/C Evaporator Coils

Check and clean the evaporator coils as needed. Monthly cleaning might be required if the coils tend to easily collect debris and dirt. Otherwise, you might need to clean them out every three months or so during the cooling season or yearly as part of your regular preventative maintenance.

Gaining Access To Clean The A/C Evaporator Coils

There should be an access to the indoor air handling unit that you can remove in order to get to the evaporator coil. Check your owner’s manual if necessary to find the evaporator coil and access panel. On the thermostat, turn your air conditioner off. To get the access loose, remove the screws or another type of fasteners. Set the screws and panel aside where you won’t separate or lose them. Check out our residential services by clicking here.

Using Compressed Air To Clean The A/C Evaporator Coils

1. You can use compressed air to remove light accumulations of materials such as dirt by blowing them off of the evaporator coil.
2. Direct the compressed air over the coil. Move in the opposite direction of regular air flow from the cleanest to the dirtiest side.
3. For pieces that are more stubborn, take the air nozzle and please near the bottom part of the debris. If high-pressure air is being used, direct it either through the fins directly or at a 90-degree angle. That will prevent the fins from getting damaged.
4. Maintain consistent airflow over the coil. That will dislodge the buildup without it being further forced into the fins which will make it harder to remove.
5. Avoid blowing debris, dirt, and dust into the living spaces of your home or into your ductwork system. Wear eye protection so that material is kept out of your eyes. Use a shop vacuum, if necessary, to collect the material as it is being dislodged.

Using A Brush To Clean The A/C Evaporator Coils

Brush cleaning is a very effective way to remove minor dirt accumulations from the evaporator coils. It enables you to avoid having to use chemicals or liquid and provides you with greater control in terms of the amount of pressure applied to the fins and coils.

• Apply your brush to the evaporator coils to sweep away dirt accumulation.
• Use the brush to scrub and break lose materials that are harder to remove.
• Avoid using a hard-bristle brush or wire brush since the might damage the fins.

Using Commercial Cleaners To Clean The A/C Evaporator Coils

There are several commercial cleaning brands that you can use to clean evaporator coils. A majority of them are foaming kinds that break down and then drain into the drainage system of the unit. Consult with a reputable local HVAC contractor for recommendations on the best clean to use for your specific situation.

Using Water And Mild Detergents To Clean Your A/C Evaporator Coils

• Apply the detergent and water solution to your evaporator coils.
• Let the solution soak in for a few minutes to that it can soak in and also loosen debris.
