Maintenance Tips

• Change or Clean Air Filters Every 1–3 Months – Accessible filters protect internal coils and blower motors, keeping airflow strong and reducing energy costs.

• Clean Evaporator & Condenser Coils Annually – Dust buildup on the all‑aluminum coil lowers heat transfer and SEER2 efficiency; professional cleaning preserves performance.

• Inspect Condensate Drain & Pan – Clear the drain line to prevent water buildup and mold growth, especially in cooling seasons.

• Check Electrical Connections & Controls – Tighten loose terminals, inspect wiring, and examine capacitors/contactors to reduce breakdown risk.

• Ensure Proper Airflow Pathways – Keep vents, louvers, and surrounding unit area clear of debris; unobstructed airflow improves comfort and efficiency.

• Monitor Refrigerant Lines & R32 Charge – Have a professional verify R32 refrigerant levels and insulation to maintain cooling capacity and prevent compressor stress.

• Schedule Annual Professional HVAC Service – Annual tune‑ups help detect combustion, heat exchanger, and burner issues early, optimizing heating and cooling year‑round.
