The time to be sure you’re going to stay warm all winter is before the weather gets too cold. Check your furnace by turning on the heat and the blower to be sure they’re operating as they should.
1. Change your furnace filter at the start of the season and then every two to four months. Filters get dirty much more quickly if your home is dusty or if you have furry or feathery pets. Clogged or dirty filters are less efficient, which means your home might not warm up properly.
2. Consider installing a programmable thermostat if you don’t have one. Programming it to be cooler at night and when you’re not at home will save you money, and you can program it to be warmer for when you return or get up on cold winter mornings.
