Keep Up With Furnace Maintenance, Especially in the Winter
Furnace filters are recommended to be replaced every month so the air flow is not restricted from dust and buildup, although every household's situation is different. For instance, high-efficiency furnaces don't need their filters changed as often, maybe every three months or when the season changes. It also depends on how many pets occupy the house, or if anyone smokes in the house.
Air vents should be cleaned out whenever dust and dirt buildup is noticed, about once every season. The process is fairly simple. Just use a screwdriver to unscrew the vent and use a vacuum hose to clean out the vent as far as it can reach, and wipe off the vent covers with a damp cloth. Air ducts are important to have professionally cleaned every three to five years, again, depending on the household's situation.
Set your thermostat so that it automatically lowers the temperature at night and raises it in the morning. Doing this can save you a sufficient amount on your furnace's operating cost. If you live in an older home and don't have a thermostat with this capability, it would be worth looking into replacing the old thermostat with a programmable one.
Always keep the area around your furnace clear and free of clutter and debris. The exhaust flue outside should always be clear of obstructions as well.
All air vents should be opened and furniture should be arranged so that it does not cover the vents or restrict air flow.
Although furnaces are relatively easy to maintain, if there are any problems or if something seems suspicious with your furnace, it is important to call a professional to handle the concerns. And always, if you smell gas coming from your furnace, call a professional immediately! Gas leaks are extremely dangerous and should not be taken lightly.
