Maintenance Tips
-
Turn off all power before performing any maintenance.
-
Replace or clean the air filter every 1–3 months to maintain proper airflow.
-
Inspect and clean the indoor evaporator coil annually to prevent dirt buildup.
-
Flush and clear the condensate drain line and pan regularly to avoid clogs and water damage.
-
Clean the outdoor condenser coil yearly and keep the surrounding area free of debris.
-
Check all electrical connections for tightness and signs of wear or corrosion.
-
Inspect gas-furnace components: burners, flame sensor, and heat exchanger for damage or soot.
-
Ensure the thermostat is functioning properly and calibrated.
-
Schedule professional maintenance twice a year (before heating and cooling seasons) to service refrigerant, blower, furnace, and system controls.
-
Keep a maintenance log of filter changes, inspections, repairs, and technician visits.
