No Heat in Winter: An Emergency Guide
Whatever your heating system, here's how to respond safely when the heat goes out in winter.
Losing heat in winter is serious for any home. This guide covers safe steps regardless of whether you have a furnace, boiler or heat pump.
Quick universal checks
Confirm power and the thermostat (HEAT mode, batteries), check the breaker and the system's own switch, replace a dirty furnace filter, and reset the unit once.
Stay safe while you wait
Use safe supplemental heating (never ovens or unvented heaters), keep the home from dropping too cold to protect pipes, and call for emergency service.
Key takeaways
- Check power, thermostat, switch and filter
- Reset the system only once
- Use only safe supplemental heat
- Protect pipes from freezing
