Maintenance Tips
-
Turn off power before performing any maintenance.
-
Replace or clean the air filter every 1–3 months to maintain airflow and efficiency.
-
Keep the outdoor unit area clear of debris and maintain at least 2 ft of clearance.
-
Clean the outdoor condenser coil and indoor evaporator coil annually to optimize heat transfer.
-
Flush the condensate drain line regularly to prevent clogs and water damage.
-
Check all electrical connections for tightness, wear, or corrosion.
-
Monitor refrigerant levels; call a technician if performance drops or leaks are suspected.
-
Test the defrost cycle during colder months to ensure proper operation.
-
Schedule professional maintenance twice a year (spring and fall) to inspect coils, blower, refrigerant, and safety controls.
-
Keep a maintenance log of filter changes, inspections, and service visits to track system health and maintain warranty coverage.
