Maintenance Tips
-
Clean the Outdoor Coil: Remove leaves, dirt, and debris regularly to maintain efficient heat transfer and optimal heating/cooling performance.
-
Maintain Proper Clearance: Keep at least 2–3 ft of space around the condenser for unrestricted airflow.
-
Inspect Refrigerant Lines: Check liquid and suction lines for insulation damage or leaks to prevent efficiency loss.
-
Rinse Fins Carefully: Use a garden hose to clean condenser fins without bending or damaging them.
-
Check Electrical Connections: Ensure wiring, disconnects, and capacitors are secure and free from corrosion.
-
Monitor Performance & Noise: Normal operation should be quiet; unusual sounds or reduced heating/cooling may indicate maintenance needs.
-
Schedule Annual Professional Service: A licensed HVAC technician should inspect the compressor, fan motor, refrigerant charge, and system pressures yearly.
