Nine out of 10 U.S. homes are under-insulated, according to an October 2024 study by ICF International. If you have central heating but fluctuating temperatures between rooms, you likely have air leaks or improper insulation in some areas of your home. Air sealing and insulating your home prevents cold air from entering and heated indoor air from leaving. It also reduces the chances of polluted air, allergens, dust, and mold in your home.
Simple tasks or improvements can lead to big energy savings; the Environmental Protection Agency (EPA) estimates that homeowners save an average of 11% on total energy costs when they add insulation and air sealing. A properly insulated attic also helps to prevent ice dams from forming on your roof, which reduces the risk of leaks and structural damage.
Check for drafts around windows, doors, and other gaps.
Apply weatherstripping around windows and doors where you feel air leaks.
Use caulk to seal gaps around window and door frames. Be sure you’re using the correct material for the material you’re sealing (e.g., acrylic latex for wood).
Seal outdoor electrical outlets with foam outlet gaskets or use a cover.
Seal the chimney damper when the fireplace isn’t in use.
Use insulation around vent pipes, ceiling fans, and exhaust fans that lead outside.
Seal leaks in your ductwork with duct sealing tape.
A safe and functional heating system is crucial for warmth and safety throughout the winter. According to the National Fire Protection Association (NFPA), heating equipment is involved in one in six reported home fires. Heating systems are also the main cause of carbon monoxide leaks, which can be deadly.
You should have your furnace or boiler inspected annually to ensure it’s working efficiently and safely, especially if it’s older. Is your heating system due for an upgrade? Consider switching to an air-source heat pump; it’s an all-electric, energy-efficient alternative that provides heating in the winter and cooling in the summer—truly a win-win.
Have a professional HVAC technician inspect your heating system regularly, especially if it’s older.
Clean or replace air filters every 1-3 months.
Clean vents or ducts before turning it on for the season.
Check ducts for holes or leaks and seal with duct tape.
Test the thermostat for accuracy—consider upgrading to a smart thermostat for better system control and efficiency.
Insulate pipes in unheated areas to prevent them from freezing.
The importance of having working smoke and carbon monoxide detectors goes without saying, but there are heightened risks in the winter. According to the NFPA, home fires happen more in the winter because of home heating, fireplaces, candles, and holiday cooking.
Meanwhile, the Centers for Disease Control and Prevention (CDC) says carbon monoxide exposure and poisoning are more likely to happen in winter because people use their furnaces and heaters more often. Carbon monoxide is a deadly chemical, especially because it comes with no warnings—it has no color, no odor, and no sign of visibility—so having a working detector is the only way to stay safe.
Check the manufacturer’s manual for specific testing instructions and maintenance recommendations.
Detectors should be installed outside bedrooms, on each level of your home, and near fuel-burning appliances.
Press the test button on the detector until the alarm sounds to confirm it’s working; if it doesn’t make a sound, you’ll need to replace the batteries or the alarm.
Make sure the alarm is loud enough to be heard throughout your home—if not, replace the batteries or the alarm.
Consider purchasing a smoke detector test spray or a CO detector tester to ensure alarms are responsive.
Check sensors for dust, debris, or discoloration and clean them with a soft brush if needed.
Power outages are inconvenient and potentially dangerous any time of year, but winter can bring bigger risks, especially if severe weather keeps you indoors. Most modern homeowners have electric, energy-efficient appliances, but the downside is that these appliances are mostly unusable during outages. We all saw the devastating effects of the Texas freeze in 2021. Preparing backup means of lighting, warmth, and communication can save money—and, more importantly, lives.
If power outages are common where you live, investing in a solar battery can be a game-changer. The setup allows you to generate your own electricity to power your home during the day and use the stored solar energy from your battery to keep the lights on at night, ensuring you’ll stay comfortable and connected even during extended outages.
Prep an emergency kit with flashlights, batteries, a first-aid kit, bottled water, non-perishable foods, and power banks.
Keep important devices fully charged.
Consider investing in a home battery or at least a portable generator to keep critical appliances running during blackouts.
Unplug appliances and electronics to avoid damage from electrical surges when the power comes back on.

You should inspect your roof before winter weather starts to get ahead of any potential issues. If there are any signs of deterioration, sagging, or leaks (even minor ones), call a professional for a full inspection.
If a roof replacement is necessary, consider adding solar panels. They'll make your roof more durable, can bring down your roofing costs, and, if you have a home battery, keep it powered during outages (as long as there's sun).
If you can’t safely get onto your roof, use binoculars to scan it for sagging, missing, or damaged shingles, or anything else that might look off.
Check the flashing around chimneys, vents, and skylights for gaps, cracks, or rust.
Remove any moss or algae that is growing on your roof.
Check your attic and ceilings for water stains, discoloration, or mold—that could mean a roof leak.
Be careful! Unless you have proper safety equipment and training, it's worth having a professional perform any work on your roof.
If your gutters are clogged with leaves and debris, water can get trapped and freeze in your gutters, which can cause damage. Ice-filled gutters are heavy, which may lead your gutters to sag, pull away from your house, or even break.
Ice dams can also lead to roof leaks or issues with your foundation if you’re not careful. On that note, you should also remove your downspout extenders to reduce ice dams.
Use a sturdy ladder placed on even ground and have someone nearby to spot you while on the ladder.
Wear thick gloves and safety goggles.
Remove leaves, sticks, and other debris from your gutters by hand or with a gutter scoop.
Flush your gutters with water to ensure water flows freely.
Check the gutters for leaks, sagging sections, or loose fasteners, and make necessary repairs.
Remove downspout extenders—clean and dry them before storing them to avoid cracks or damage.
These might seem like small chores, but disconnecting your hose and protecting your pipes from freezing can help you avoid costly damage to your home. It’s best to turn off your outdoor water supply and disconnect garden hoses before winter weather starts for the season.
Inside, let a small trickle of water run from your faucets when temperatures dip to prevent your pipes from freezing. If you're going to be away during the winter, turn off your water and open all of your faucets (including showers and toilets) to drain your pipes. Or, have a plan in place for someone to come over and do it for you should a cold snap occur. Trust us: We've seen burst pipes cause a lot of damage that costs a lot of money. It's best to be prepared.
Shut off the valve to your outdoor water supply to prevent water freezing in the pipes.
Disconnect hoses from your foundation and drain them of water before you store them. Store them inside a garage, shed, or basement so they don’t crack.
Cover outdoor faucets with foam or insulated covers.
Insulate exposed pipes with foam insulation or heat tape.
Let a small trickle of water run from faucets when temperatures drop below zero.
Keep your heat on a minimum of 55°F, even when you’re away, to protect pipes from freezing. Remember those smart thermostats we referenced earlier? Those can come in handy here.
Open cabinet doors under sinks to expose your pipes to warmer air.
Many of the above tips help optimize your home’s overall efficiency, which reduces the risk of winter-related hazards—and can help save you money. For example, sealing air leaks and improving insulation keeps your home’s temperature warm and consistent throughout the season, and maintaining or upgrading your heating system reduces the risk of fire and carbon monoxide leaks. Most of the tips we’ve outlined are DIY-friendly, but if you’re ever feeling overwhelmed or unsure how to address some of these tasks, call a professional.
