How to Clean AC Coils

Cleaning your AC coils is essential for maintaining the efficiency and longevity of your air conditioning system. Follow these steps to effectively clean your AC coils:

Step 1: Turn Off the Power

Before you begin, ensure that the power to the air conditioning unit is turned off. This is crucial for your safety.

Step 2: Access the Coils

Remove the access panel to reach the evaporator coils and condenser coils. Depending on your unit, you may need a screwdriver or a wrench.

Step 3: Inspect the Coils

Check for any visible dirt or debris on the coils. If they appear heavily soiled, a thorough cleaning is necessary.

Step 4: Use a Coil Cleaner

Apply a commercial coil cleaner or a mixture of water and mild detergent. Spray the cleaner generously on the coils and let it sit for a few minutes.

Step 5: Rinse the Coils

After allowing the cleaner to penetrate, rinse the coils gently with water. Avoid using a high-pressure hose, as it can damage the fins.

Step 6: Allow to Dry

Let the coils dry completely before reassembling the unit. This helps prevent moisture buildup, which can lead to mold growth.

Step 7: Reassemble and Restore Power

Once the coils are dry, replace the access panel and restore power to the unit. Turn on your air conditioning and check for proper operation.
