Cleaning A Mitsubishi Mini Split Air Conditioner

Cleaning a Mitsubishi mini split air conditioner is an essential task for homeowners who want to maintain optimal performance and indoor air quality. Mini split systems have become popular among homeowners due to their ability to provide precise heating and cooling control for individual rooms, along with potential energy savings. By following these simple steps, you can ensure that your Mitsubishi mini split remains efficient and effective in keeping your home comfortable.

Step 1: Cut The Power

Turn off the system by turning off the circuit breaker for the indoor and outdoor units.

Step 2: Clean The Filters

Lift the front cover of the indoor unit and remove the filters. Vacuum the filters with a brush attachment. If the filters are heavily soiled, wash them with soap and warm water, ensuring they are completely dry before reinserting them.

Step 3: Clean The Heat Exchanger

Use the brush attachment of your vacuum to clean the delicate fins of the heat exchanger inside the unit.

Step 4: Clean The Fan

Remove the bottom cover and clean the fan blades, fan motor, and cooling coils using a vacuum. If there is visible dust, gently wipe the area with a dry cloth.

Step 5: Clean The Condensate Pan

Wipe up any moisture in the pan located at the bottom of the unit. Ensure the drain hose is functioning correctly. If there is standing water or blockage, use white vinegar to clear it.

Step 6: Remove Debris

To maintain the energy efficiency of a ductless system, you need to clean the loose debris from the indoor and outdoor units.

Step 7: Vacuum and Wash Grilles

Use a vacuum or dry cloth to remove dirt from the heat exchange grilles. If the grilles are heavily soiled, use liquid soap and a garden hose to wash them.

Step 8: Clean Inside Of Housing

Unscrew and remove the top of the outdoor unit, wipe down the fan blades, and vacuum the interior, including the condenser coils.

Step 9: Clean Condensate Pan and Hose

Wipe the drain pan with a cloth and address any mold growth with a bleach solution. Clean the hose with vinegar.
