Keep The Flame Burning With Gas Furnace Maintenance

Summer is the perfect time to perform routine maintenance on your gas furnace. An annual check-up ensures that your furnace equipment lasts longer and operates at peak energy efficiency. Your heating contractor can help you keep the flame burning longer in your natural gas furnace, saving you money on replacement costs and energy bills.

Maintaining a Natural Gas Furnace

An annual maintenance from a licensed heating contractor now can prevent untimely heater breakdowns in the cold winter months, and save you money on repair and replacement costs. Expect to pay between $100 and $200 for a thorough check-up. Your heating contractor should inspect:

  • heat exchanger
  • electronic ignition system
  • fan, motor, bearings, belts, pumps
  • air filter and electronic air cleaner
  • burners, pilot, and pilot safety system
  • furnace controls
  • venting
  • thermostat

Annual maintenance of your gas furnace ensures that all motorized equipment is operating safely and efficiently. A licensed heating contractor understands the heating mechanism and the safety codes associated with it. In addition to tests and inspection, the furnace may require adjustments, burner cleaning, repairs, or replacement of worn parts.

What You Can Do

Between heating contractor visits, you can take certain precautions to extend the efficiency and lifespan of your natural gas furnace. A gas furnace maintenance check should also include tests for carbon monoxide and for leaks in the gas pipes. Union Gas Energy company advises their customers to complete the following easy maintenance tasks throughout the year:

  1. Clean or replace the air filter on your gas furnace. A dirty filter reduces airflow and energy efficiency, which makes your furnace work harder. Replace the filter every month or two.
  2. Ensure that gas furnace heating vents, radiators, and return air grills remain unobstructed. It's important to ensure free airflow at each point of the delivery system, both for energy conservation and safety reasons.
  3. Some older gas furnaces require lubrication of the blower motor. Ask your heating contractor if this maintenance is necessary.
  4. Replace frayed belts.

Poorly maintained gas furnaces can lead to problems ranging from energy inefficiency to carbon monoxide poisoning. An ounce of prevention, in these cases, is worth a pound of cure--contact a heating contractor to ensure your gas system's flame keeps burning throughout the chilly winter season.
