No Heat During a North Georgia Ice Storm: Kennesaw Emergency Steps

When the Heat Quits and the Temperature Is Dropping

North Georgia does not see ice often, but when it does, it arrives fast. A warm afternoon turns into freezing rain overnight, tree limbs come down on power lines, and by morning half of Kennesaw is checking the thermostat and getting nothing back. If your furnace has gone silent while sleet ticks against the window, the first thing to do is stay calm and work through the situation in order.

The 2014 storm that locals still call Snowmageddon taught a lot of Cobb County families how quickly a comfortable house cools once the heat stops. A well-insulated home in Shiloh Hills or Legacy Park may hold livable temperatures for several hours, but an older, drafty house can lose that buffer before lunchtime. Knowing what to check, and what to leave alone, keeps a bad night from becoming a dangerous one.

First: Rule Out the Simple Causes

Before you assume the furnace has failed, confirm it is actually getting the chance to run. Ice storms knock out power and trip breakers constantly, and a furnace with no electricity cannot ignite even if the gas is flowing.

• Check your thermostat: is the display lit, set to Heat, and set several degrees above the current room temperature? Replace the batteries if the screen is dim or blank.
• Look at your electrical panel for a tripped furnace breaker and reset it once. If it trips again immediately, stop and leave it off.
• Confirm the furnace switch on the unit itself, which looks like a light switch, is in the on position. It gets bumped off more than you would think.
• Make sure the gas is on if you have propane or natural gas, and that a whole-home shutoff was not closed during earlier work.

Protect Your Pipes Before the House Gets Cold

In a Georgia freeze, frozen pipes cause more expensive damage than the lost heat itself. Once indoor temperatures start sliding toward the 40s, water sitting in lines along exterior walls and in the crawl space is at risk. A burst pipe during an ice storm can flood a home while you are still waiting on the power company.

Open cabinet doors under kitchen and bathroom sinks so warmer room air reaches the plumbing. Let a pencil-thin stream of water run from the faucet farthest from your main line, since moving water resists freezing. If you know where your main shutoff is, confirm you can reach it quickly in case a line does let go.

Stay Warm Safely: The Carbon Monoxide Rule

This is the part of an ice storm that sends Cobb County families to the emergency room every few years. Never heat your home with a gas oven, a charcoal or propane grill, or an outdoor generator running in the garage. These produce carbon monoxide, a gas you cannot see or smell, and it kills in an enclosed space.

Close off unused rooms and gather the household into one central space. Layer clothing, use blankets and sleeping bags, and share body heat. If you run a portable generator to keep essentials going, place it well outside and away from windows and doors. Test the battery in your carbon monoxide detector now, while you are thinking about it, not after something goes wrong.

What Actually Breaks a Furnace During a Storm

When the power flickers on and off during an ice event, the surges and outages are hard on furnace electronics. Control boards, igniters, and blower motors are the parts we replace most often in the days after a freeze. High-efficiency furnaces also vent through PVC pipes that exit the side of the house, and those intake and exhaust pipes can ice over or get blocked by sleet, which trips a safety lockout and shuts the unit down.

If your furnace tries to start, runs briefly, then quits, or if you see a blinking light behind the access panel, note the pattern. That blink code tells a technician a great deal before we even arrive. Do not keep cycling the power hoping it catches, because repeated failed ignition attempts can flood the burner area with unburned gas.

When to Stop Troubleshooting and Call a Technician

Some situations are not a wait-and-see. Call for help right away, and leave the house if needed, if you smell gas, if you see or smell smoke, or if a carbon monoxide alarm sounds. Those are not furnace problems to diagnose yourself.

Short of that, call for emergency furnace service when you have checked the thermostat, breaker, and unit switch and still have no heat, especially with a house full of children, older adults, or anyone with a health condition. Our emergency furnace repair team works through ice events across Kennesaw, and we would rather talk you through a safe fix on the phone than have you climb into a cold crawl space in freezing rain.
