Homeowner’s Winter Checklist

From clearing the gutters to installing new furnace filters and everything in between, knocking out this homeowner’s winter checklist before the temperatures stop dropping will keep your home warm and running efficiently this winter.

  • Winterize air conditioning units. Remove any window AC units and store them in a dry location, like an attic or basement. Use the original box for storage if you still have it. For outdoor air conditioners, cut power to the unit by unplugging it during the winter and cover the top part with a piece of plywood or plastic to prevent anything, like icicles or tree limbs, from falling inside and causing damage. Don't completely cover the entire air conditioning unit, which includes the sides, as it can cause moisture issues and provide shelter to critters looking to stay warm.
  • Tune-up your furnace. Hire an HVAC professional from Aire Serv® to thoroughly inspect your furnace, lubricate bearings, adjust the pilot light, and more. Consistent tune-ups can extend the life of your furnace and eliminate unexpected repair needs.
  • Clean fireplace and chimney. A buildup of creosote—the black, sooty substance that sticks inside a chimney after a season of burning wood—can release toxic fumes into your home or spark a chimney fire. That's why it's so important to hire a certified chimney sweep at least once per year. Gas-powered and electric fireplaces don’t produce creosote, but it’s a good idea to clean out any dust that may have built up.
  • Clear gutters. Rain and melting snow that can't drain properly if leaves and debris are clogging your gutters. Eventually this causes leak or mold issues inside your roof, attic, and your home’s walls.
  • Install and test carbon monoxide detectors. Most CO injuries and deaths occur in cold-weather months. Install CO detectors on every floor of your home and especially near gas-fired appliances that can cause CO leaks, such as the clothes dryer, furnace, water heater, stove, and gas-powered fireplace. Test the alarms regularly to keep you and your family safe from this silent killer.
  • Install new furnace filters. Furnace filters capture everything from dirt and mold to bacteria. Changing that filter monthly in the winter cuts down on those things spreading throughout your home and helps keep your furnace running efficiently in the colder months when it’s needed the most.
  • Reverse your ceiling fan. The counterclockwise direction is used in the summer to push down cold air. Reverse the blades' direction to clockwise in the winter to recirculate heat and take some load off your heating system.
  • Inspect windows for drafts. Air leaks, especially those around windows and doors, can keep your furnace working overtime. Find the source of the leak, then seal it with new weather stripping or caulking.
  • Insulate air ducts. This is especially important for ducts in the basement, floors, and ceilings because it helps regulate temperatures by preventing any hot air from leaking out. Hire an HVAC expert to make sure the job is done right.
  • Buy a smart thermostat. Minimize energy costs by heating your home only when you need to, automatically. Today's smart thermostats learn your routines, automatically turning up the heat as you get home from work and turning it back down again when you normally go to sleep. And if you leave and forget to turn down the furnace, you can adjust it from anywhere with your phone app.
