Safety Precautions: Before you begin, make sure to turn off the power to the AC unit to avoid any accidents.

Cleaning the Air Filters: Dirty air filters can reduce your AC's efficiency. Follow these steps to clean the filters:

  • Remove the front grille of the AC unit. The filters are usually located behind it.
  • Take out the filters and gently tap them to remove loose dust and debris.
  • Use a soft brush or a vacuum cleaner with a brush attachment to clean the remaining dirt from the filters.
  • If the filters are washable, you can wash them with a mixture of mild detergent and water. Rinse thoroughly and allow them to dry completely before reinserting.

Cleaning the Evaporator Coils: The evaporator coils can accumulate dust and dirt over time, affecting cooling performance. Here's how to clean them:

  • Access the evaporator coils by opening the access panel on the indoor unit. Refer to your AC's manual for guidance.
  • Use a soft brush to gently remove loose dirt and dust from the coils.
  • If there's stubborn dirt, you can use a water hose to carefully spray water on the coils. Ensure that the water pressure is not too high, and avoid spraying directly onto electrical components.
  • Let the coils dry completely before closing the access panel.

Cleaning the Condenser Coils: The condenser coils are located in the outdoor unit and can also accumulate dirt and debris. Here's how to clean them:

  • Turn off the power to the outdoor unit.
  • Use a brush or a vacuum cleaner to remove leaves, grass, and other debris from around the unit.
  • Gently hose down the condenser coils with water to remove dirt and dust. Again, be cautious not to use high water pressure that could damage the coils.
  • Allow the coils to dry before restoring power to the unit.
