Maintenance Tips

• Clean or Replace Filters Regularly: Inspect and clean the air handler’s filters monthly to maintain optimal airflow and efficiency — clogged filters reduce performance.

• Dust Internal Components: Periodically dust the blower, cabinet interior, and accessible coil surfaces to prevent buildup that can impede airflow and efficiency.

• Check Condensate Drain Lines: Ensure the condensate drain and trap are clear of obstructions to prevent water backup or leaks.

• Maintain Clear Surroundings: Keep the unit’s installation space free of clutter to ensure proper airflow and easy access for service.

• Inspect Ductwork: Periodically inspect connected ducts and connections for leaks, loose insulation, or damage that can reduce system efficiency.

• Annual Professional Service: Schedule yearly HVAC inspection to clean coils thoroughly, check electrical connections, verify refrigerant and ensure long‑term reliable performance.

• Monitor for Odd Performance: If airflow weakens, odd noises occur, or temperatures fluctuate, contact a qualified technician early to diagnose potential issues.
