As a homeowner, it can be easy to overlook important home maintenance, but with winter approaching, there’s one task in particular you’ll want to complete. And that’s getting your furnace in tip-top shape.
That bulky metal box in your basement (or crawl space, attic, or even hall closet, depending on where you live) is what produces the warm air that keeps your house cozy, making it possibly the most important piece of winter equipment in your home.
The good news is that furnace maintenance is relatively easy: a combination of simple do-it-yourself tasks and an annual tune-up by a professional. Here’s how to get it done.
Furnace Tasks You Can Do
Inspect the air filters. The Environmental Protection Agency’s Energy Star program suggests doing a monthly check of your furnace’s air filter and replacing it when it looks dirty. Frequent changes prevent the accumulation of dirt and debris, which can reduce efficiency and lead to equipment failure. Changing the filter is especially important if you’re new to the home—who knows what dust and grime others left behind? Tip: To make sure you’re buying the right filter, check your existing one; the size is usually printed on the side.
Maintain a carbon monoxide detector. A failing furnace can leak carbon monoxide, so you’ll want to keep a battery-operated or battery-backup carbon monoxide detector in your basement (and every level of your home), according to the National Fire Protection Organization, placing it at least 15 feet away from the furnace to avoid a false alarm. Tip: Change detector batteries in the spring and fall, on daylight saving day, when you change your clocks.
Keep vents clean and clear. Before you turn on your system for the season, remove all the heating vent covers from the floors and ceilings around your home, and vacuum out the ducts. Dust, pet dander, and all those toy soldier pieces that seemingly go missing can collect there, causing your furnace to work harder. Tip: When cleaning ceiling vents spread a sheet on the floor and wearing goggles to shield your eyes from falling dust.
Tasks Best Left to the Professionals
Annual tune-up. A pre-season checkup by a professional is an absolute must to help prevent costly problems down the road. A heating contractor will make sure that your thermostat is working accurately and that your system is cycling on and off properly, and will typically go through a series of checks and tasks, including:
- Tightening loose electrical connections
- Oiling all the moving parts
- Inspecting all gas connections
