As the weather’s getting cooler, you’re probably going to be using your furnace more. The last thing you want in the middle of winter is for your furnace to stop working. Brrr.
Luckily, there are lots of things you can do year-round to help keep your furnace running smoothly this winter. Dirt wastes fuel and lowers efficiency, making it your furnace’s biggest enemy. In some cases, dirt can cause the furnace to overheat.
The parts of the furnace that should be cleaned are the filter system, the motor, and the blower.
- Replace the Filter. The filter should be cleaned or replaced at the beginning of heating season and once a month during periods of continuous use. If the filter looks clogged, you should replace it regardless of time of year or time of last use. Installing a programmable digital thermostat can help you save energy and will also notify you when the filter should be replaced.
- Oil the Motor and Blower if you have an older natural gas or propane furnace. A couple of drops of 20-weight oil once a year should be sufficient. Most newer models have sealed bearings that don’t need to be oiled.
- Bleed Air out of Radiators Annually if you have a hot water system. While the system is on, open the bleeder valve on each radiator until water comes out without sputtering. Be prepared to catch the water. Be careful—the water will be hot!
- Prevent Blockage. Make sure that all outside vents and chimneys are not blocked by snow, leaves, nests, or anything else. Blockages can cause carbon monoxide hazards, which can be fatal. Leaks can also cause carbon monoxide hazards and fires, so make sure there are no cracks or separated joints.
