Maintenance Tips
-
Replace Air Filters Every 1–3 Months – Clean filters protect the indoor coil and blower, maintaining proper airflow and system efficiency.
-
Clean Evaporator & Condenser Coils Annually – Dust and debris on all‑aluminum coils reduce heat transfer and SEER2 efficiency.
-
Inspect Refrigerant Lines & TXV – Ensure R32 refrigerant lines are leak-free and the thermostatic expansion valve regulates refrigerant correctly for efficient cooling/heating.
-
Maintain Proper Airflow – Keep supply and return vents clear and ensure blower fans operate without obstruction for optimal performance.
-
Check Condensate Drain & Pan – Prevent water buildup and microbial growth by keeping the condensate drain clear.
-
Inspect Electrical Components – Regularly check contactors, capacitors, and wiring for wear or corrosion to prevent failures.
-
Schedule Professional Annual Maintenance – Technicians should check refrigerant levels, clean coils, verify SEER2 performance, and ensure safe multi-positional heat pump operation.
