Furnace Tune-Ups in Arden and Asheville, NC

• Standard one-inch air filters are replaced or cleaned, and the blower motor and wheel are inspected.
• On gas and oil furnaces, burners are cleaned, the heat exchanger is examined, the pilot or ignition system is cleaned and adjusted, and the flue and exhaust venting are inspected.
• Gas valve or fuel oil pump pressures are measured, proper combustion is verified, and combustion is adjusted for optimal efficiency.
• On oil furnaces only, the oil filter and nozzle are replaced and the ignition electrodes are adjusted.
• On heat pumps, our technician examines the coils, tests the contactors, relays, and reversing valve, runs the defrost cycle, reads refrigerant pressures and temperatures, and tests the electric strip heat.
• Voltage and amperage draw on the motors are measured, and capacitors are inspected and tested.
• Lubrication goes to all serviceable motors, bearings, and fans, and the electrical wiring is examined and tightened.
• Temperature rise and airflow are measured, the thermostat is evaluated, and the controls for safety and operation are tested and adjusted.

Oil furnaces need fuel-side service that gas equipment does not: a new oil filter and nozzle, and adjusted ignition electrodes. Heat pumps need their own checks, including the reversing valve, the defrost cycle, and the electric strip heat. Gas furnaces get pressure and combustion verification. A tune-up protects you only when it matches the equipment, so each fuel gets its own steps.

Verified combustion means fuel becomes heat instead of waste, and the heat exchanger and venting inspections keep that combustion contained. Staying on a regular service schedule also protects your manufacturer’s warranty.
