Winter home maintenance checklist
Quick answer
Winter maintenance is about preventing freeze damage and staying safe with the heat running. Keep the home heated even when you're away, let faucets drip in extreme cold, know where your main water shutoff is, keep gutters and roof edges clear to prevent ice dams, and test your carbon-monoxide and smoke detectors. A little attention now heads off burst pipes and no-heat emergencies — the costliest winter failures.
What to check first
- Keep indoor heat at about 55°F or higher even when away, so pipes don't freeze.
- In deep cold, let faucets drip and open cabinet doors on exterior walls.
- Make sure the main water shutoff is accessible and everyone knows where it is.
- Clear gutters and rake snow off the roof edge to prevent ice dams.
- Test smoke and carbon-monoxide detectors — CO risk rises when heating runs.
- Reverse ceiling fans to clockwise to push warm air down.
- Keep exhaust vents and the furnace flue clear of snow.
When it's urgent
Freeze protection is the priority — a burst pipe is the most common and costly winter failure. If you'll be away, never let the house go unheated, and consider a smart thermostat or a freeze alarm that warns you if the temperature drops.
DIY vs. call a pro

How HouseCue helps
HouseCue is a private, homeowner-first app that turns this from a one-time worry into a tracked plan. Snap a photo for an AI diagnosis, upload your inspection report to auto-build a handbook, and get seasonal reminders for your roof, HVAC, water heater, plumbing, and electrical — so nothing slips. Connecting with a pro is always optional and only when you choose.
Get started freeFrequently asked questions
What temperature should I set my thermostat to when away in winter?
Keep it at about 55°F or higher — low enough to save energy but warm enough to keep pipes from freezing. In very cold climates or during a hard freeze, set it higher and let faucets drip; never turn the heat fully off while away.
How do I keep my pipes from freezing while I'm away?
Keep the heat on (about 55°F+), let a couple of faucets drip, open cabinet doors on exterior walls, and make sure exposed pipes are insulated. For longer absences, consider shutting off and draining the water, or using a freeze alarm.
Why is carbon-monoxide risk higher in winter?
Furnaces, fireplaces, and other combustion appliances run far more in winter, and homes are sealed up tight — so a venting problem or cracked heat exchanger can let CO build up. Test detectors at the start of the season and replace batteries.
