Maintenance Tips

• Replace Air Filters Monthly: Use high-quality filters and replace every 1–3 months to ensure optimal airflow and protect the blower motor.

• Keep Vents & Registers Clear: Ensure supply and return vents are unobstructed for efficient heating and even distribution.

• Inspect Venting System: Check intake and exhaust pipes for blockages, debris, or damage to maintain safe combustion.

• Clean Around the Furnace: Keep at least 2–3 ft clearance from dust, storage, or debris to prevent airflow restrictions and fire hazards.

• Monitor Blower & Noise Levels: The variable-speed blower should run quietly; unusual sounds may indicate mechanical or dust issues.

• Check Thermostat & Power Supply: Verify thermostat settings, gas supply, and 115V circuit operation for consistent heating.

• Schedule Annual Professional Service: Have a licensed HVAC technician inspect burners, heat exchanger, gas pressure, ignition system, and safety controls yearly.
