ROUTINE MAINTENANCE
COILS AND BASE PAN
The indoor coil (evaporator coil), the outdoor coil
(condenser coil) and base pan should be inspected

debris (lint, dirt, leaves, paper, etc.). Clean the coils
and base pan with a soft brush and compressed air
or vacuum. If using a pressure washer, be careful
