What to Do When Your Heat Goes Out in an Oklahoma Ice Storm

Central Oklahoma gets hit with at least one or two serious ice storms most winters. If you've been through one, you know the drill — freezing rain, downed power lines, and bitter cold that doesn't let up for days. Losing your heat during one of these events is more than uncomfortable. It can be dangerous.

Here's what to do if it happens to you.

Immediate Safety Steps

First, figure out why the heat stopped. The answer determines your next move.

Check if you have power. If the lights are off, it's a power outage, not an HVAC failure. Contact OG&E or your power provider and check their outage map.
Check your thermostat. Make sure it's set to heat, the temperature is set above the current room temperature, and the batteries aren't dead. This sounds obvious, but we get calls for this more often than you'd think.
Check your breaker panel. A tripped breaker for the furnace or air handler is a quick fix. Flip it back and see if the system restarts.
Check your furnace filter. A completely clogged filter can cause a system to shut down on a safety limit. If it's packed solid, replace it and restart the system.

If none of those solve it, you're dealing with an equipment failure that needs a technician.

Space Heater Safety

When the heat goes out and you're waiting for a repair or for power to come back, space heaters become the backup plan. Use them carefully.

Electric space heaters only — Never use propane heaters, kerosene heaters, or your gas oven/stove to heat your home. The carbon monoxide risk is real and it kills people in Oklahoma every winter.
Keep heaters 3 feet from anything flammable — curtains, bedding, furniture, clothing.
Don't use extension cords — Plug space heaters directly into a wall outlet. They draw enough current to overheat a cheap extension cord.
One heater per room, one room per family — Consolidate into a single room with a door you can close. Hang blankets over windows. You'll stay warmer heating one small space than trying to warm the whole house.
Never leave a space heater running while you sleep — Use it to warm the room, then switch it off. Pile on the blankets instead.

Preventing Frozen Pipes

When indoor temperatures drop below 40 degrees, your pipes are at risk. Burst pipes cause thousands of dollars in damage and it happens across the Norman, Moore, and Purcell area every time we get a hard freeze with extended power outages.

Open cabinet doors under kitchen and bathroom sinks, especially on exterior walls, to let warmer air reach the pipes.
Let faucets drip — A slow, steady drip from both hot and cold taps keeps water moving through the pipes and reduces the chance of freezing.
If you leave the house, don't turn the heat below 55 degrees — and if the power is out, consider shutting off the main water supply and opening faucets to drain the lines.
Know where your water shutoff is before an emergency. If a pipe does burst, you need to cut the water immediately.

Generator Safety and Carbon Monoxide

Generators save a lot of discomfort during winter outages, but they are the leading cause of carbon monoxide poisoning deaths during storms in Oklahoma.

Never run a generator indoors — not in the garage, not in the basement, not even in a carport. Outside only, at least 20 feet from any window or door.
Carbon monoxide is odorless and colorless. You won't know it's there until people start getting sick — headaches, dizziness, nausea. By then it's a medical emergency.
Install battery-powered CO detectors on every level of your home. Test them before storm season. This is non-negotiable.
If your CO detector goes off, get everyone outside immediately and call 911.

What Causes Winter HVAC Failures

The most common reasons we see heating systems fail during the worst weather:

Frozen outdoor unit — Heat pumps can ice up in freezing rain. The defrost cycle should handle normal frost, but a heavy ice storm can overwhelm it. If the entire outdoor unit is encased in ice, the system can't function.
Failed ignitor or flame sensor — On gas furnaces, these components wear out and tend to fail right when you need them most because the system is running harder than it has in months.
Tripped safety limits — Dirty filters, blocked vents, or a malfunctioning blower can cause the system to overheat and shut down on a high-limit switch.
Power surges after an outage — When power is restored, the surge can damage control boards. A whole-home surge protector is a good investment.
Lack of maintenance — Systems that haven't been tuned up in years are far more likely to fail under heavy demand.

When to Call for Emergency Service

If your heat is out, temperatures are below freezing, and you have vulnerable people in the house — elderly family members, young children, or anyone with health conditions — don't wait. That's a genuine emergency.

Trinity Climate Control provides emergency heating service across the Central Oklahoma area, including Norman, Moore, Purcell, Blanchard, Newcastle, and Goldsby. We know that ice storms don't happen on convenient schedules, and we respond accordingly.

If you can stay safe and warm enough with space heaters for the night, a morning service call is fine. But if you're unsure, call. We'd rather answer the phone and talk through your options than have you take a risk with your family's safety. You can also reach us through our contact page.
