Winterizing a Northern Nevada Home: Your First-Year Checklist

If you're coming from a milder climate, the first Northern Nevada winter is the one that catches you. Nights drop below freezing regularly from late fall through early spring, and one cold night can burst a pipe or expose an aging furnace. Work through this checklist before the first hard freeze and in roughly this order.

Know your local winter

In Carson City, winter (December through February) averages about 36 degrees, with overnight lows in the low 20s, and the city averages about 14 inches of snow a year. Reno is similarly cold with comparable snowfall; higher-elevation communities and the Tahoe basin can see much more. (Source: NOAA 1991-2020 climate normals, Carson City)

Protect the pipes (the expensive surprise)

Disconnect and drain garden hoses before the first freeze. Shut off and drain exterior spigots where they have shutoffs, insulate hose bibs, and insulate exposed pipes in crawl spaces, garages, and along exterior walls. Know where your main shutoff valve is. Pipes are genuinely at risk when temperatures reach the low 20s; on the coldest nights, let a slow drip run from hot and cold faucets. If you'll be away in deep cold, keep the thermostat at 55 degrees or higher and have a neighbor or a leak sensor watch the house.

Furnace and heat

Have your furnace or heat pump serviced once a year before the cold season and replace the filter about every 90 days. NV Energy recommends 68 degrees while you're home and about 55-60 when you're away; also close foundation vents for the winter, open curtains on the sunny side during the day, and close them at dusk. Replace smoke and carbon monoxide detector batteries, and make sure the CO detector works: a gas furnace running for months with closed windows is exactly when CO matters.

Roof, gutters, and snow

Clean the gutters before the first snow so ice dams don't form. Northern Nevada roofs are built to local snow-load requirements, and those requirements vary by county and elevation, so never guess: your county building department sets the official ground snow load for new work or a re-roof. After a storm, clear snow away from the foundation and walkways, and don't climb onto a snow-covered roof without proper equipment.

New-homeowner extras

Locate your main shutoff valve, water heater, and breaker panel now, not during an emergency. Set the water heater to about 120 degrees. Know whether you heat with gas, electric, or a heat pump. If you're listing a home or leaving it vacant in winter, keep the heat at 55 degrees or higher so pipes don't freeze while no one is home.

This post is general information drawn from NOAA climate normals, NV Energy guidance, and standard home-safety practice as of late 2026. Confirm furnace service, snow-load questions, and insurance details with your licensed HVAC professional, county building department, and agent.
