A furnace is not too complicated. But just like changing the oil in your car, the furnace also needs to be maintained to keep it running at its very best. A furnace should be serviced once a year. This is usually best in the fall, before winter sets in and you need heat. The first tip to gas furnace maintenance is to keep it clean. A dirty furnace will not run as efficiently as a clean furnace.
When cleaning the furnace, be sure to disconnect the power supply first. Next, remove the access panels and use a vacuum with a soft brush attachment to clean the blower blades and motor. If there is any rust on the metal parts, use a wire brush to remove it. Then, replace the access panels and reconnect the power.
Another important part of maintaining a furnace is changing the filter regularly. A dirty filter will not only make the furnace run less efficiently, but it can also lead to premature wear and tear on the motor. Most filters should be changed every three months. Lastly, it is important to keep an eye on the pilot light. If the pilot light goes out, the furnace will not work. If you notice the pilot light is flickering or seems to be burning weaker than usual, it may be time to call a professional for service.
