What to Do If Your Furnace Stops Working During Extreme Cold

When extreme cold hits Dayton, Ohio, a furnace breakdown is more than inconvenient — it can quickly become a safety concern. Allied Services, Inc. regularly responds to no-heat calls during harsh winter weather, helping homeowners restore warmth when temperatures drop fast and heating systems are pushed to their limits.

Check Your Thermostat First

Before assuming the furnace has failed, check that your thermostat is set to heat and the temperature is higher than the current room temperature. If the thermostat is battery-powered, weak batteries can cause it to stop communicating with your heating system during cold weather. Also, make sure programmable thermostats haven’t been reset due to a power outage.

Inspect Your Circuit Breaker and Furnace Switch

Extreme cold can strain electrical components. Check your breaker panel for tripped breakers and make sure the furnace power switch is turned on. If a breaker keeps tripping, avoid repeatedly resetting it, as this could indicate an electrical or motor issue that requires professional attention.

Replace or Check Your Air Filter

A clogged air filter can restrict airflow and cause the furnace to shut down as a safety precaution. During extreme cold, furnaces run longer, and filters clog faster than usual. Replacing a dirty filter improves airflow and can sometimes restore heat while preventing additional strain on the system.

Watch for Warning Signs

Unusual noises, burning smells, or cold air blowing from vents can signal a mechanical problem. If you notice any of these signs, stop troubleshooting and do not run the system further. Continuing to operate a malfunctioning furnace can lead to more extensive damage or safety risks.
