Drain Pan
Inspect the condenser coil, evaporator coil, and condensate
drain pan at least once each year.
The coils are easily cleaned when dry; therefore, inspect and
clean the coils either before or after each cooling season.
Remove all obstructions, including weeds and shrubs, that
interfere with the airflow through the condenser coil.
Straighten bent fins with a fin comb. If coated with dirt or lint,
clean the coils with a vacuum cleaner, using the soft brush
attachment. Be careful not to bend the fins. If coated with oil or
grease, clean the coils with a mild detergent and water solution.
Rinse coils with clear water, using a garden hose. Be careful
not to splash water on motors, insulation, wiring, or air filter(s).
For best results, spray condenser coil fins from inside to
outside the unit. On units with an outer and inner condenser
