Maintenance Tips

• Replace Air Filters Every 1–3 Months – Clean filters in the air handler maintain airflow and protect indoor coils, preserving cooling efficiency.

• Keep Outdoor Condenser Clear – Remove leaves, grass, and debris around the outdoor unit and gently rinse the coil with a garden hose to maintain heat transfer and airflow.

• Annual Coil Cleaning – Have a technician clean both condenser and evaporator coils annually to prevent dirt buildup that lowers SEER2 performance.

• Inspect Refrigerant Lines & Insulation – Ensure R32 lines are well‑insulated and checked for leaks; correct levels support efficient operation.

• Check Electrical Components Yearly – A pro should test capacitors, contactors, and connections for wear or corrosion to avoid failures.

• Maintain Unit Clearance & Level Pad – Keep ~2–3 ft of space around the condenser and ensure it’s level to support airflow and long‑term durability.

• Schedule Annual Professional Maintenance – Professional tune‑ups before peak cooling seasons help optimize performance, check pressures, and uphold warranties.
