What to Do When Your Heater Stops Working in the Middle of Winter

Tom Markley • December 10, 2025

A heater breaking down during winter is every homeowner's nightmare. Beyond the discomfort, freezing temperatures can pose serious health risks. If your heater stops working, don’t panic—follow these steps to troubleshoot the issue and keep your home safe and warm.


1. Check Your Thermostat Settings

Make sure your thermostat is set to “Heat” and that the temperature is higher than the current room temperature. If your thermostat runs on batteries, check and replace them if necessary.

Pro Tip: Smart thermostats may lose connection to Wi-Fi. Reconnect them if needed to ensure accurate settings.


2. Inspect the Power Source

  • Electric Heaters: Check your circuit breaker box for tripped breakers and reset them if needed.
  • Gas Furnaces: Ensure the pilot light is lit. If it’s out, follow your system’s manual to relight it carefully.
  • Oil Furnaces: Verify there’s enough oil in the tank. If it’s empty, schedule a refill immediately.


3. Replace Dirty Air Filters

Clogged air filters can block airflow, causing your heating system to shut down or work inefficiently. Replace your air filter if it looks dusty or clogged, and keep a schedule to check it monthly during heavy use.


4. Inspect Vents for Blockages

Ensure vents and registers throughout your home are open and unobstructed by furniture, rugs, or debris. Restricted airflow can overwork your heating system.


5. Look for Error Codes

Modern heating systems often display error codes on their control panels. Refer to your system’s user manual or look up the code online to identify the issue.

Not sure how to interpret the code? Call us for assistance! Our technicians are experts in troubleshooting HVAC systems.

6. Use Temporary Heating Solutions Safely

If the heat can’t be restored immediately, use these alternatives carefully:

  • Portable space heaters: Keep them on a flat surface, away from flammable materials.
  • Fireplaces: Ensure proper ventilation to avoid carbon monoxide buildup.
  • Blankets and layers: Bundle up and use extra bedding to stay warm.


7. Call a Professional HVAC Technician
