When the heat stops on a cold Greenville night, the first question isn’t whether the thermostat needs a new setting. It’s whether anyone in the home needs to get outside before you touch the system. A carbon monoxide alarm, a gas odor, or symptoms of carbon monoxide poisoning turn a heating failure into an immediate safety issue.
The safest response is to rule out immediate danger, make only visible checks, and use temporary heat carefully while arranging service. The steps below explain what to do as the house cools.
Leave Immediately for Carbon Monoxide or Gas
Leave the house immediately if a carbon monoxide alarm sounds, you smell gas, or someone has symptoms consistent with carbon monoxide exposure. Carbon monoxide is an odorless, colorless gas that can kill without warning, so don’t stay inside to locate the source or reset the alarm.
Get everyone outside, including people who are asleep, young children, older adults, and anyone who may not be able to explain how they feel. Once you’re safely outside, call 911. Don’t reenter until emergency responders say it is safe.
Watch for these symptoms of carbon monoxide poisoning:
- Headache, dizziness, weakness, nausea, or vomiting.
- Chest pain, confusion, or unusual drowsiness.
- Multiple people in the home feeling sick at the same time.
A gas odor also calls for evacuation rather than furnace troubleshooting. Don’t operate electrical switches, light matches, use a lighter, or try to restart heating equipment. Heating service comes after the home is safe, not before.
Make Only Safe, Simple Checks
If there is no sign of carbon monoxide, a gas leak, smoke, or a medical emergency, a few visible checks may reveal a simple issue. Stop if you notice a burning odor, repeated breaker trips, water around the equipment, unusual noises, or any reason to question whether the system is operating safely.
Before requesting service, check these basics:
- Thermostat Settings
Confirm the thermostat is set to Heat and that the temperature setting is above the current room temperature. Replace the batteries if the screen is blank and the thermostat uses them. - Circuit Breaker
Look for a tripped breaker serving the heating system. Reset it once. If it trips again, leave it off and request service rather than repeatedly resetting it. - Air Filter
Check an accessible filter. A heavily clogged filter can restrict airflow and contribute to system shutdowns. Replace it with the correct size if you have one on hand.
Don’t open the furnace cabinet, bypass a safety switch, work on fuel connections, or attempt electrical repairs. Never use a gas oven to heat a home. Annual heating service helps identify problems before a cold-night breakdown creates an emergency.
Stay Warm Without Creating Another Hazard
Use layers, blankets, warm drinks, and one occupied room to retain body heat while service is on the way. Close interior doors to unused rooms, but keep enough of the home open to protect plumbing in cold areas. If household members can’t stay warm, go somewhere heated.
A portable space heater requires careful use. Keep it at least three feet from bedding, curtains, furniture, clothing, and other combustible items. Plug it directly into a wall outlet, never into a power strip or extension cord.
Turn the heater off when you leave the room or go to sleep. Never use charcoal grills, camp stoves, or fuel-burning appliances indoors. Keep a portable generator outdoors, more than 20 feet from windows, doors, and vents, because its exhaust creates a deadly carbon monoxide hazard.
Protect People & Plumbing As the House Cools
Cold exposure becomes more serious as indoor temperatures fall, especially for infants, older adults, people who are ill, and anyone who is wet or unable to add dry clothing. Hypothermia is a medical emergency and can occur even above 40 degrees Fahrenheit when someone is wet.
In adults, signs include shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech, and drowsiness. Call 911 if a person is unconscious or appears to have no pulse or breathing. Move the person away from the cold while emergency assistance is being arranged.
Frozen pipes are another concern during a prolonged heating outage. Open cabinet doors beneath sinks on exterior walls so warmer air can reach the plumbing, and keep interior doors open where practical. If you see frost on exposed pipes, experience a loss of water pressure, or find water leaking from a pipe, treat it as a plumbing emergency.
When to Request Emergency Heating Service
Request emergency HVAC repair for a complete loss of heat, signs of an electrical or combustion problem, or an indoor temperature that is becoming unsafe. When you call, be ready to share:
- The equipment type and thermostat setting.
- Any unusual symptoms, odors, or noises.
- Whether a breaker has tripped.
- Any alarm activity.
