January Home Safety Checklist: Pipes & CO
The coldest month brings the highest risk for frozen pipes, CO poisoning, and radon buildup
Data source: EPA, NWS, CDC, CPSC Last updated: June 2026
Why January Is a Critical Month for Home Safety
January is consistently the coldest month across most of the United States. According to NOAA data, the average January temperature for the contiguous U.S. is 30.7°F — well within the danger zone for residential plumbing, heating systems, and indoor air quality.
Three hazards converge in January: frozen pipes, carbon monoxide from overworked heating systems, and peak indoor radon concentrations due to sealed-up homes. Each is preventable with the right checklist.
Frozen Pipe Prevention
The Insurance Institute for Business & Home Safety estimates that frozen pipe failures cause $1.2 billion in property damage annually in the U.S. A single burst pipe can release 4–8 gallons of water per minute.
January Pipe Protection Checklist
- Insulate exposed pipes in crawl spaces, attics, garages, and along exterior walls with foam pipe sleeves (R-value of 3+ recommended)
- Let faucets drip when temperatures drop below 20°F — focus on lines running through unheated spaces
- Open cabinet doors under kitchen and bathroom sinks to let warm air circulate around pipes
- Keep thermostat at 55°F minimum even when away — the cost of heating is far less than water damage repair
- Know your main water shut-off valve location — if a pipe bursts, shutting off the supply within minutes limits damage
- Disconnect outdoor hoses and close interior shut-off valves to exterior faucets if not done in fall
- Check for air leaks near where pipes enter the home — seal gaps with caulk or spray foam
NWS alert pattern: The National Weather Service issues the most Freeze Warnings and Hard Freeze Warnings during the first three weeks of January, peaking around January 7–15 in northern states.
Carbon Monoxide Safety
Carbon monoxide is an odorless, colorless gas produced by fuel-burning appliances — furnaces, water heaters, fireplaces, generators, and gas stoves. January's heavy heating demand makes it the peak month for CO incidents.
CO Safety Checklist
- Test all CO detectors — press the test button on every unit and replace batteries (or replace units older than 5–7 years)
- Schedule a furnace inspection if you have not had one this heating season — cracked heat exchangers are the #1 source of residential CO leaks
- Never use a generator indoors — not in garages, basements, or enclosed porches. Generators should be at least 20 feet from any window or door (CPSC recommendation)
- Clear furnace vents and chimney flues of snow and ice — blocked vents force CO back into the home
- Do not use gas ovens or stovetops for heating — this is a leading cause of CO poisoning in cold snaps
- Check fireplace dampers — open when in use, confirm the flue is drawing properly
Data point: The CPSC reports that portable generators alone cause an average of 70 CO-related deaths per year, with January storms being the most dangerous trigger.
Radon Testing Season
January is one of the best months to test for radon. The EPA recommends testing during the coldest months because closed-house conditions produce the highest — and most representative — radon readings.
Radon Action Items
- Buy a short-term radon test kit ($15–$30 at hardware stores or free through many state radon programs)
- Place the test on the lowest livable level, away from windows and exterior doors, for 2–7 days
- EPA action level: 4 pCi/L — if your result exceeds this, the EPA recommends mitigation. Consider action at 2–4 pCi/L as well
- If you have well water, test water for radon separately — dissolved radon in water is released into indoor air during showers and cooking
- Check your ZIP code on ZipCheckup to see your area's radon risk zone and whether your county has elevated radon levels
Why January matters: The stack effect — warm air rising through the home — is strongest in winter. This negative pressure at the foundation draws soil gas (including radon) into the home at higher rates than any other season. Studies show winter radon levels average 60% higher than summer levels in the same home.
Water Heater Winter Check
Your water heater works hardest in January, with incoming water temperatures at their lowest (often 40–50°F vs. 65–75°F in summer). This means longer run times, higher energy bills, and more stress on the unit.
- Check the temperature-pressure relief (TPR) valve — lift the lever briefly to confirm it operates freely
- Flush 1–2 gallons from the drain valve to clear sediment — sediment buildup reduces efficiency and accelerates tank corrosion
- Inspect the anode rod if the unit is 3+ years old — a depleted rod means the tank itself is corroding
- Set temperature to 120°F — the EPA-recommended setting that balances Legionella prevention with scald safety

Residential Electricity Rates
Current residential electricity rates from EIA (2026-01):
- National average: 17.98¢/kWh
- Highest: HI at 39.79¢/kWh
- Lowest: ND at 10.92¢/kWh
Winter heating drives electricity bills to seasonal highs in many regions. Running your thermostat at 68°F instead of 72°F can save 8–12% on heating costs.
Air Quality Snapshot
Current EPA AirNow readings across 28,592 ZIP codes (as of 2026-06-01):
| AQI Category | ZIP Codes |
|---|---|
| Good (0–50) | 15,172 |
| Moderate (51–100) | 13,035 |
| Unhealthy for Sensitive Groups | 385 |
Currently, 1.3% of monitored areas show elevated air quality concerns. Check your ZIP code report for local conditions.
Winter inversions can trap pollution near ground level in valleys and urban areas, degrading indoor air quality in tightly sealed homes.

Winter's closed windows mean indoor lead dust accumulates faster. Wet-mopping and HEPA vacuuming reduce exposure. Check your ZIP code for local lead risk.
Energy Mix & Efficiency
Current energy generation data from EIA across 51 states (2025):
- 26.9% average renewable energy share
- 41.1% average clean energy share (including nuclear)
- Top solar: NV (30.3%)
- Top wind: IA (58.9%)
States with higher renewable mix tend to have more stable winter pricing. Heat pump adoption can cut heating costs 30-50% vs. electric resistance.
Equipment Lifespan Check
Key home equipment to inspect this winter:
| Equipment | Avg. Lifespan | Replacement Cost |
|---|---|---|
| Furnace | — years | — |
| Water Heater (Tank) | — years | — |
Service HVAC equipment before peak season to avoid emergency rates and extend lifespan.

Frequently Asked Questions
At what temperature do pipes freeze?
Pipes are at risk when outdoor temperatures drop below 20°F (-6°C) for an extended period. The American Red Cross recommends letting faucets drip and opening cabinet doors when temperatures drop below 20°F. Uninsulated pipes in exterior walls, attics, and crawl spaces freeze first. NWS data shows that January accounts for the highest number of freeze warnings issued annually across the continental U.S.
Why is radon testing recommended in winter?
Winter is the ideal time to test for radon because homes are sealed tightly with windows closed, creating worst-case conditions. The EPA recommends testing during the heating season (October–March) for the most accurate results. Radon levels can be 2–3 times higher in winter than summer due to the stack effect — warm indoor air rises and draws radon-laden soil gas through foundation cracks.
How many people die from carbon monoxide poisoning each year?
The CDC reports approximately 420 people die from unintentional CO poisoning in the U.S. each year, with more than 100,000 emergency department visits. January and February see the highest rates, driven by heating equipment failures and improper use of generators and fuel-burning appliances during winter storms. The CPSC recommends CO detectors on every level of the home.
Should I let my faucets drip during a freeze warning?
Yes. The American Red Cross recommends letting cold water drip from faucets served by exposed pipes during freeze warnings. Even a slight trickle relieves pressure buildup in the pipe — it is the pressure between the ice blockage and the faucet that causes pipes to burst, not the ice itself. Focus on faucets along exterior walls and in unheated areas.
