man and woman shivering with coats on indoors

It’s cold out and your heat stopped working. What now? We know what a worry it is to find that your heater won’t turn on, especially if you’ve got little ones around. Your first instinct might be to call a professional — and we’re always happy to help, but sometimes the solution is as simple as a flip of a switch. That’s why we put together this list of six things to check before calling a pro the next time your house feels like the inside of a freezer.

What to check when your heat stops working

  1. Check the batteries in your thermostat. If you haven’t had your air conditioner or furnace maintenance done in the last two to three years, there is a good possibility the batteries need to be replaced.
  2. Check your thermostat settings. Make sure it’s turned to the heat function and set to 72 degrees. It’s not uncommon for another member of the household to make changes to the thermostat that results in the furnace being turned off or the temperature setting being cooler than desired.
  3. Check your furnace unit. Is it on? It’s not uncommon for the furnace switch to be accidentally turned off. Always double-check that the switch is in the ON position — you can find the switch on the side of your furnace.
  4. Check your circuit breaker. Open the panel and find the breaker switch that’s connected to your furnace. Has it been tripped? If so, reset it by moving the switch to its OFF position, then back to ON.
  5. Check your furnace filter. Make sure it has been installed properly and doesn’t need to be replaced. A clogged filter can restrict airflow and cause your furnace to stop working. Change your filter regularly to help prevent furnace shutdowns.
  6. Check the outside vents to ensure nothing is obstructing the airflow.
