What You'll Need
Vacuum
Container for storing screws while you clean
Rags
Screwdriver
Filter (if necessary)
Spray cleaner
Soft bristle brush

No matter what type of air conditioner you have installed or use in your home, the air conditioner coils need to be cleaned regularly to avoid mold growth. The air conditioner coils also need to be cleaned right away if mold is present. Removing mold is important because it can cause health problems and grow quickly if not treated. The more mold is present, the more those exposed to it will experience health issues. This is especially true for those that have asthma or other allergies. When mold is left to grow in an air conditioner it can be spread throughout the home when the air is on. This will happen rapidly if there is high humidity in the home or surrounding area. Use the following cleaning tips to help in removing mold and preventing further accumulation.

Step One – Remove Filter

The first thing you need to do is remove the filter, setting aside any screws you remove. There are some air conditioning models with filters that are meant to be cleaned and used again. For this type, submerse the filter in warm, soapy water to soak while the rest of the unit is cleaned. For disposable filter types, dispose of the used filter appropriately.

Step Two – Remove Grill and Cover

Next, remove the grill and cover from the air conditioner, again setting aside any screws you remove.

Step Three – Remove Back Frame

Depending upon the type of unit, removing the back frame is the next step. Keep the screws safe and find the coils, fins, and fan motor.

Step Four – Clean the Innards

Now is time for general cleaning and removing any mold that is present. Vacuum away any loose debris and dust first. Then, spray your chosen spray cleaner onto the rag. Gently wipe away any dust, mold and accumulated water. Repeat the process until the unit is clean. If necessary, use the soft bristled cleaning brush to gently scrub away any stubborn mold or dirt.

Use a clean, warm rag to wash away any cleaning product. Clean up and thoroughly dry all parts of the coils and fins. If any pieces were bent during the cleaning process, reshape them.

Step Five – Dry and Reassemble Unit

Before beginning the process of putting the air conditioner back together, be sure all parts are dry. This will help prevent mold from occurring again. Using the screws you stored, replace all framing and other parts. If your unit requires a new filter, attach it -- or, replace the cleaned one.

All air conditioner systems should be cleaned at least once per year. Make sure to clean thoroughly before you store the unit. Fix any leaks in your air system right away to prevent mold.
