Christmas Day Property Safety — Heat, Lights, Snow

I’m Timothy Jacobs, owner of Lawn Harmony Landscaping in Circleville. Christmas Day is the one day of the year I genuinely hope nobody calls me, and the way to make that happen is for property owners to do a quick safety pass on the morning of the 25th. I’ve put together this post based on the calls I do get every Christmas Day — the heating issues, the holiday light problems, the snow and ice surprises, and the small things that turn a peaceful morning into a stressful afternoon. None of this takes more than 30 minutes if you build it into the Christmas morning routine.

What’s the right Christmas Day property safety checklist?

Six items, in this order on Christmas morning: check the furnace is running and the thermostat shows expected temperature, walk the exterior to confirm no overnight storm damage or downed limbs, check that the front walk and driveway are clear of ice for arriving guests, verify all exterior holiday lights are functioning and not overloading circuits, confirm the carbon monoxide and smoke detectors are functioning, and look at the propane or natural gas tank or meter for any visible issue.

Thirty minutes Christmas morning prevents most of the emergency calls that come in by 2 p.m. when guests are arriving, ovens are running, and everybody’s distracted.

On a Canal Winchester property I monitored on Christmas Day 2024, the homeowner did the morning walk and noticed a downed maple limb resting on the back deck railing. Wind from overnight had snapped it cleanly. He cleared it himself before grandkids arrived to play in the back yard. Without that walk, the limb would have stayed there until somebody bumped it.

What heating system risks should I check Christmas morning?

Three: furnace operation, vent clearance, and unusual smells. Furnaces work hardest on the coldest days of the year, and Christmas in Central Ohio often falls in the coldest week. Per the OSU Extension household energy guidance, a healthy furnace cycles roughly every 15-30 minutes in 20-degree weather and maintains thermostat setpoint within 2 degrees.

If your furnace is running constantly without reaching setpoint, you have either a sizing issue, a duct issue, or an aging system that needs a service call. None of those are Christmas Day fixes, but knowing about them on the 25th gets the service call scheduled for the 26th instead of finding out at midnight on the 27th.

Vent clearance matters because snow can drift against exterior furnace vents and high-efficiency exhaust pipes on the side of the house. Per Ohio EPA guidance on combustion appliance safety, a blocked exhaust vent on a high-efficiency furnace can lead to carbon monoxide buildup in the home. Walk the perimeter, check the vents, clear any drifted snow.

A Bexley client lost a furnace ignition cycle Christmas morning 2023 because of drifted snow against a sidewall vent. The furnace tried, failed, and locked itself out by 5 a.m. He woke up to a 58-degree house. A 90-second walk the night before would have prevented the issue entirely.

What about holiday lights on Christmas Day?

Two risks: overloaded circuits and damaged extension cords. Strings of holiday lights running continuously for two-plus weeks accumulate heat in connection points, and damaged outdoor cords are the leading cause of residential holiday electrical fires per the National Fire Protection Association’s seasonal data.

Walk the exterior. Look for any lights that are dim, flickering, or off when they should be on. Look for any extension cord connections that have melted or discolored insulation. Look for any cord runs that have been disturbed by snow shoveling, wind, or pets.

Indoor tree lights are the other piece. A Christmas tree that’s been up for three weeks with continuously running lights and a dry water reservoir is a fire risk. Christmas morning, check the water level on the tree stand and refill if dry. If the tree feels noticeably lighter than it did when it went up, it’s drying out and the lights should come off when nobody’s in the room.

A Grove City customer had a circuit breaker trip Christmas Day 2022 because their tree lights and three extension cords were drawing 22 amps off a 15-amp circuit. The breaker did exactly what it was supposed to do, but the family was scrambling to find the panel during dinner prep.

What snow and ice issues come up Christmas Day?

Three: walkway clearance for arriving guests, driveway ice for arriving vehicles, and roof ice dams developing from overnight refreeze.

The walkway is the most common surprise. A walk that was clear Christmas Eve afternoon can be ice by Christmas morning if there was any melt-refreeze cycle overnight. Treat any wet-looking surface with calcium chloride before guests arrive. If you treated Christmas Eve, a touch-up application Christmas morning is the right move.

Driveway ice causes the slip-and-fall calls I do get. An aunt with a hip replacement stepping out of a car onto an icy driveway is a real Christmas emergency. Salt the driveway entrance specifically where car doors open and where guests transfer between car and walkway.

A Lancaster property I service had a guest fall Christmas Day 2024 on a driveway that looked clear but had an inch-wide refrozen melt line right at the car-door step. Bruised hip, no break, but a scary moment that derailed two hours of the day. The homeowner now does a salt pass on the car-door area every Christmas morning regardless of conditions.

What about ice dams on the roof?

Ice dams form when snow on a warm roof melts at the warm peak, runs down to the cold eave, and refreezes. The resulting ridge of ice forces subsequent meltwater back up under shingles. By Christmas Day, ice dams typically have had two or three days of formation.

The signs to look for from the ground on Christmas morning: long icicles at the eaves over 12 inches, visible ice ridges along the gutter line, water staining on the soffit, or water dripping inside near exterior walls. Any of those signals an active ice dam.

Christmas Day is not the day to handle an active ice dam. The right move is to document it with phone photos, move any furniture or valuables away from the wall where interior water staining is showing, and call a qualified roofer December 26 or 27. Trying to chip ice off a roof on Christmas Day with family in the house is how someone ends up in the ER.

What about carbon monoxide and smoke detectors?

Press the test button on every detector before guests arrive. The Ohio Fire Marshal’s holiday safety guidance specifically calls out the increased fire and CO risk during the holiday week from increased oven use, fireplace use, and furnace runtime.

Detectors with low-battery chirps are the call I’d most hate to get on Christmas morning. Twenty seconds per detector confirms function and resets any pending low-battery notification.

What about the grill, propane tank, or outdoor heating?

If you’re running a propane patio heater or fire pit for outdoor entertaining, check the tank level and the regulator before guests arrive. A propane tank that runs dry mid-evening with no spare is a common Christmas frustration. Keep a backup 20-pound tank in the garage.

Gas grills used for Christmas Day cooking should be cleared of any snow on the lid before opening and warmed up gradually. Per the NFPA grill safety guidance, gas grills used outdoors in winter conditions account for a small but real share of holiday property fires from rapid heat-up combined with grease buildup.

When should I call for help on Christmas Day?

For property emergencies on Christmas Day, call the relevant service first. Furnace failures call your HVAC company’s emergency line. Roof leaks from ice dams call a roofer. Major snow events on commercial properties call your snow contractor. For exterior issues I can address, call my line at 614-425-9789 and I’ll triage what’s urgent. I do answer the phone Christmas Day for existing clients and existing snow contracts, but I’m not running new account intake on the 25th.
