It's 2AM in January, the temperature outside is 8°F, and you wake up to a cold house. Your furnace isn't running. This is not a situation where you can wait until morning — in a Fort Wayne winter, a home without heat can drop to dangerous temperatures within hours, and the risk of frozen pipes in older homes is real. Here's exactly what to do, in order, when your furnace fails during a Fort Wayne winter night.

Step 1: Don't Panic — Check the Basics First

Before calling for emergency service, run through these quick checks. They take two minutes and occasionally save a service call. First, check your thermostat — verify it's set to "Heat" and that the temperature setting is above the current room temperature. Check that your thermostat has working batteries. A dead thermostat battery is one of the most common "emergency" calls we receive in Fort Wayne, and it's a free fix.

Check your circuit breaker panel and look for any tripped breakers. Your furnace typically has a dedicated breaker — flip it fully off, then back on. If it trips again immediately, stop and call us. Also check that the power switch on the furnace unit itself (it looks like a light switch, usually on the wall near the unit) is in the "on" position. These switches get accidentally bumped more often than you'd think.

Check your gas supply. If other gas appliances in your home (stove, water heater) are also not working, you may have a gas supply issue rather than a furnace problem. In that case, call your gas utility — NIPSCO for most Fort Wayne residents — first. If you smell gas anywhere in your home, leave immediately and call 911 from outside before calling anyone else.

Step 2: Try Resetting the Furnace

Most modern furnaces have a reset button — typically a small red button on the burner assembly. If the furnace has shut itself off on a safety lockout, pressing reset will attempt to restart it. This is worth trying once. If the furnace starts but shuts off again within a few minutes, do not keep pressing reset — repeated resets without correcting the underlying problem can damage components. Call for service.

Check your furnace's filter. A severely clogged filter can trigger a high-temperature safety shutoff that prevents the furnace from running. Pull the filter out, and if it's visibly clogged, run the furnace without the filter in place temporarily while waiting for service. This is not a long-term solution, but it may restore heat while you wait.

Step 3: Protect Your Home While Waiting for Help

While you wait for our technician to arrive, take steps to protect your Fort Wayne home from the cold. Open cabinet doors under all sinks — especially in exterior walls — to allow warmer room air to circulate around pipes. If you have portable electric space heaters, set them up in the rooms you're occupying and in the kitchen and bathrooms near exterior walls. Keep interior doors closed to concentrate the available heat.

Do not use a gas stove, oven, or outdoor grill to heat your home. Carbon monoxide poisoning is a serious risk with any of these improvised heating methods. Keep everyone — especially children and elderly family members — in the warmest available rooms and add extra blankets.

If the home temperature drops below 55°F and help is more than a few hours away, consider going to a 24-hour location — a hotel, a 24-hour restaurant, or a family member's home — especially if children, elderly, or medically vulnerable people are in the household.
