Maintenance Tips
-
Keep Unit Clear of Debris: Regularly remove leaves, grass, snow, and other debris around the outdoor condenser to maintain proper airflow and efficiency.
-
Clean Coils Annually: Have a technician clean the outdoor coil fins each year to prevent dirt buildup that can reduce heat exchange efficiency and performance.
-
Inspect Refrigerant Lines: Periodically check refrigerant lines and connections for leaks or damage; refrigerant work should only be done by certified HVAC professionals.
-
Ensure Proper Drainage: Make sure the condensate and base pan drains are unobstructed to prevent water buildup or ice accumulation around the unit.
-
Check Mounting & Vibration: Inspect mounting bolts and outdoor unit supports occasionally to ensure secure installation and minimize vibration.
-
Professional Yearly Service: Schedule annual professional maintenance to verify refrigerant levels, check electrical components, and optimize performance before peak cooling/heating seasons.
-
Clean Exterior Surfaces: Wipe down the outdoor unit’s exterior casing and fins with a soft brush or cloth; avoid harsh chemicals and high‑pressure washing.
