1. Inspect air filter(s) each month. Clean or replace when necessary. Certain geographical locations may require more frequent inspections.
2. Inspect indoor coil, outdoor coil, drain pan, and condensate drain each cooling season for cleanliness. Clean at least once per heating /
cooling season or more often if needed.
3. Inspect blower motor and wheel for cleanliness at the beginning of each heating and cooling season. Clean when necessary. Forfirst heating
and cooling season, inspect blower wheel bi-monthly to determine proper cleaning frequency.
4. Check electrical connections for tightness and controls for proper operation each heating and cooling season. Service when necessary.
5. Ensure wires are not contacting refrigerant tubes or sharp sheet metal edges.
