For the last couple of years, winter has felt more like a mild inconvenience than an actual season. A few chilly mornings, maybe a threat of snow, and then nothing but a child's wish forgotten. Many of us started to believe we’d somehow negotiated a permanent truce with winter altogether.
And then… finally single-digit temperatures showed up and snow arrived.
In light of the recent cold snaps and true winter weather making an appearance again, it felt like a good time to dust off (literally and figuratively) some reminders on how to protect your home during the colder months. Whether this winter ends up being short-lived or sticks around a bit longer, a little preparation now can help prevent frozen pipes, power outages, and surprise repairs later.
Consider this your friendly, just-in-case guide — because winter has clearly decided it’s not ready to be forgotten yet.
Below is a practical winter checklist, with special attention to vacant homes, plumbing protection, generators, and solar systems.
General Winter Maintenance Essentials
Before winter fully sets in, it’s smart to take care of a few fundamentals:
Replace HVAC filters and make sure heating systems are serviced.
Seal air leaks around doors, windows, attic access points, and crawlspace vents.
Clean gutters and downspouts so melting snow and ice can drain freely.
Trim branches near the roof and power lines that could break under ice or snow.
Test smoke detectors, carbon monoxide detectors, and emergency lighting (Flashlights) .
Make sure exterior hoses are disconnected and spigots are turned off.
These steps reduce strain on systems, help lower heating costs, and protect against moisture intrusion.
Heat Pump Care During Winter, Ice Storms, and Heavy Snow
Heat pumps have become increasingly common, especially in homes focused on efficiency and electric systems. They work extremely well in cold climates—but ice storms and heavy snow bring a few extra things to keep in mind.
Before Cold Weather Hits
Change or clean filters regularly to maintain airflow.
Confirm the defrost cycle is working. Modern heat pumps automatically melt ice buildup; if yours isn’t defrosting properly, efficiency drops quickly.
Check drainage from the outdoor unit so melted ice has a clear exit path.
During Ice Storms or Snow Accumulation
Keep the outdoor unit clear. Gently remove snow and ice buildup, making sure not to damage fins or coils.
Never chip ice aggressively or pour hot water directly on the unit—this can crack components.
Allow clearance on all sides. Outdoor heat pump units need airflow even in winter, so drifting snow can cause problems if not cleared.
Listen for unusual sounds. Loud grinding, clicking, or constant defrost cycling may signal ice obstruction or mechanical strain.
Power Outages and Heat Pumps
Heat pumps rely entirely on electricity. During outages:
Homes without backup power will lose heat quickly in very cold weather.
Homes with generators or battery systems should confirm that the heat pump is included as a critical load if capacity allows.
Some homes are equipped with secondary heat sources (wood stoves, gas fireplaces, or resistance backup heat), which can be important during extended outages.
After the Storm Passes
Inspect the unit for lingering ice, debris, or bent fins.
Reset system settings if there was a power interruption.
Schedule service if performance feels reduced or uneven.
Heat pumps are reliable and resilient—but like any system, they perform best when protected from heavy ice buildup and airflow obstruction.

Generator Maintenance and Winter Preparation
If your home relies on backup power, winter is when generators are most valuable—and most likely to fail without maintenance.
Whole-House Generators
These are permanently installed, connected to your fuel source (natural gas or propane), and automatically turn on during outages.
Winter maintenance includes:
Monthly automatic exercise runs (confirm they are scheduled and working).
Annual professional servicing.
Checking battery condition (cold temperatures reduce battery performance).
Keeping snow and ice away from vents and exhaust ports.
Portable Generators
These require manual setup and fueling and can be powered by Propane, Gasoline, or Natural Gas.
Winter prep tips:
Run the generator periodically to keep carburetors clean.
Use fuel stabilizer and rotate stored fuel every few months.
If using Propane, portable propane tanks may need to be stored in a location above freezing prior to being used in an outage.
Store the generator in a dry location (never indoors or in garages while running).
Keep extension cords, oil, and spare spark plugs accessible.
Important reminder: portable generators must always be used outdoors, far from windows and doors, to prevent carbon monoxide poisoning.
Solar Panels and Battery Systems: Preparing for Winter Outages
Homes with solar panels and battery storage systems have a major advantage during outages—but winter changes how they operate.
Winter considerations:
Snow may reduce solar production temporarily.
Storms may limit grid-tie systems unless paired with batteries.
Preparation tips:
Confirm batteries are set to retain sufficient backup reserve.
Test backup mode before severe weather arrives.
Clear snow from panels if safe to do so.
Ensure critical loads (refrigeration, heat systems, well pumps) are prioritized on the backup circuit.
Battery storage provides silent, automatic power during outages—but maintenance checks ensure it works when you need it most.

If Your Home Will Be Vacant During Winter
Whether you’re traveling for a week or leaving for several months, vacant homes require extra planning during winter.
Minimum steps for short absences (a few days to two weeks):
Set the thermostat no lower than 55°F.
Leave interior cabinet doors open under sinks to allow warm air to reach pipes.
Have someone check the home periodically, especially after major freezes.
Shut off exterior water lines if possible.
For longer absences:
Shut off the main water supply.
Drain water lines and appliances (details below).
Add antifreeze to toilets and drain traps.
Unplug nonessential electronics.
Notify a trusted neighbor or property manager.
Water damage from frozen or burst pipes is one of the most common—and expensive—winter issues in vacant homes.
How to Prevent Pipes From Freezing
Pipes freeze when temperatures drop below 32°F and air circulation or insulation is poor.
Key prevention steps:
Insulate exposed pipes in crawlspaces, basements, and garages.
Seal foundation penetrations where cold air enters.
Keep garage doors closed if plumbing runs nearby.
Let faucets drip slightly during extreme cold if the water supply remains on.
If a home will be unattended, draining the water system is the safest option.
Step-by-Step: How to Drain and Bleed Water Lines (Including Hot Water Heater)
What you’ll need:
Adjustable wrench
Hose (for water heater)
Bucket or floor drain access
RV/plumbing antifreeze (non-toxic)
Step 1: Turn off the main water supply
Locate the main shutoff valve and turn it fully off.
Step 2: Turn off the water heater
For electric heaters: turn off the breaker.
For gas heaters: turn the control knob to “pilot” or “off.”
Allow the water to cool before draining.
Step 3: Open all faucets
Start with the highest fixture in the home and work downward. Open both hot and cold taps. Flush toilets to drain tanks.
Step 4: Drain the hot water heater
Attach a hose to the drain valve at the bottom of the tank.
Run the hose to a floor drain or exterior location.
Open the drain valve and open the pressure relief valve at the top.
Let the tank fully empty.
Step 5: Drain remaining water lines
If available, open any low-point drains in the plumbing system. Leave all faucets open once drained.
Step 6: Protect traps and toilets
Pour RV antifreeze into all sink drains, tubs, showers, and floor drains.
Add antifreeze to toilet bowls and tanks.
Step 7: Final check
Make sure all valves are open and no water remains trapped. Label the main water shutoff clearly before leaving.
A Final Word
Winter maintenance is about prevention, not panic. Taking time now to protect plumbing, power systems, and your home’s core components can save thousands in repairs and give you peace of mind—whether you’re home all season or away enjoying winter elsewhere.
If you ever have questions about preparing a home for winter, or how certain systems affect resale value and insurance, I’m always happy to help.
