Cleaning the Air Filters

  1. Accessing the Air Filters: Locate the front panel of the indoor unit and remove it to access the air filters.
  2. Removing the Filters: Carefully remove the air filters from the unit.
  3. Cleaning the Filters: Wash the filters with a mild detergent and water. Gently scrub the filters to remove any accumulated dust or debris.
  4. Drying the Filters: Allow the filters to air-dry completely before reinstalling them.
  5. Reinstalling the Filters: Once the filters are dry, place them back into the unit, ensuring they are properly aligned and secured.

Cleaning the Evaporator Coil

  1. Accessing the Evaporator Coil: Remove the cabinet of the indoor unit to access the evaporator coil.
  2. Inspecting the Coil: Visually inspect the evaporator coil for any signs of dirt, mold, or other contaminants.
  3. Cleaning the Coil: Use a clean, dry cloth or a cloth dampened with coil cleaner to gently wipe away any dirt or debris from the coil’s surface.
  4. Reassembling the Unit: Once the coil is clean, replace the cabinet and front panel of the indoor unit.

Cleaning the Condensate Pan

  1. Locating the Condensate Pan: Identify the location of the condensate pan, which is typically located at the base of the indoor unit.
  2. Inspecting the Pan: Check the condensate pan for any mold growth or accumulated debris.
  3. Cleaning the Pan: If necessary, clean the pan and drain with a solution of soapy water or a mild bleach solution.
  4. Checking the Drain: Ensure that the condensate drain is clear and unobstructed.

Cleaning the Outdoor Unit

  1. Removing Debris: Inspect the outdoor unit and remove any twigs, leaves, or other debris that may have accumulated around or on the unit.
  2. Cleaning the Exterior: Use a garden hose or a coil cleaning tool to spray down the exterior of the outdoor unit, removing any dirt or grime.
  3. Wiping the Housing: Use a clean cloth to wipe down the housing of the outdoor unit, removing any remaining dirt or debris.
