Cleaning the Outdoor Unit

The outdoor unit, or condenser, is outside. It often gets dirty with dirt, leaves, and debris. Cleaning it helps with airflow and efficiency. Here is how to clean the outdoor unit:

Step-by-Step Cleaning:

  1. Turn off the Power: As mentioned, safety first. Turn off the power at the circuit breaker.
  2. Inspect the Unit: Look for large debris, like leaves, twigs, or grass. Remove anything that is in the way by hand.
  3. Clean the Fins: Use a garden hose with a spray nozzle. Gently rinse the fins from the inside out. Avoid bending the fins.
  4. Apply Coil Cleaner: Spray the AC coil cleaner on the fins. Follow the product instructions. Let it sit for the recommended time.
  5. Rinse the Unit: Gently rinse the fins again with the garden hose. This removes the cleaning solution and any remaining dirt.
  6. Straighten Bent Fins: Use a fin comb to straighten any bent fins. This improves airflow.
  7. Check for Obstructions: Make sure nothing is blocking the unit and restricting airflow.

Cleaning the Indoor Unit and Air Filters

The indoor unit, or evaporator, also needs regular cleaning, especially the air filters. Here is how to clean the indoor unit and air filters effectively:

Step-by-Step Cleaning:

  1. Turn off the Power: Make sure the power is off at the circuit breaker.
  2. Remove and Clean Air Filters: Find the air filters, usually behind a grille. Remove them and clean them.
  3. Clean the Filters: Wash reusable filters with mild soap and water. Rinse them well and let them dry completely. Replace disposable filters.
  4. Inspect the Evaporator Coil: Check the evaporator coil for dirt and debris.
  5. Clean the Evaporator Coil: Use a vacuum cleaner with a brush attachment to gently remove dust and debris from the coil.
  6. Clean the Blower Fan (Optional): If you are comfortable doing so, you can also clean the blower fan, but be very careful.
  7. Reassemble the Unit: After everything is clean and dry, put the unit back together. This includes the air filters and any panels you removed.
