Emergency Heating Repairs: What to Do When the Heat Goes Out

Posted on January 29th, 2026 by Ferocious Digital

A sudden loss of heat during a cold spell isn’t just uncomfortable—it can be a genuine emergency. When your furnace quits unexpectedly, knowing the right steps can help you stay safe and restore warmth quickly. The team at Devine Bros. knows how stressful this can be, which is why we’ve put together this guide on what to do when your heat goes out.

First Steps in a Heating Emergency

Before calling for professional help, there are a few simple checks you can perform. These steps can sometimes resolve the issue or provide valuable information for your technician.

First, check your thermostat. Ensure it’s set to “heat” and the temperature is set higher than the current room temperature. A dead thermostat screen could indicate a simple battery issue, so try replacing them.

Next, examine your circuit breaker. A tripped breaker is a common culprit for a furnace that won’t turn on. Locate your electrical panel and see if the breaker for your heating system has been switched to the “off” position. If it has, reset it.

Check Your Fuel Supply and Vents

If you use oil or propane, confirm you haven’t run out of fuel. Also, walk around your home and ensure all heating vents are open and unobstructed by furniture, rugs, or other items. For furnaces, check the air filter. A severely clogged filter can restrict airflow and cause the system to shut down.
