Will Your Gas Furnace Work During a Blackout?

It is a common misconception that your gas furnace will work even without electricity. Unfortunately, this is not the case.

The circuit boards, blower motors, relays and thermostat all require a supply of electricity to operate. This means that if you are subjected to a blackout, you cannot rely on your gas heater to keep you warm.

Everything you need to know about your heating system during a black out 

What should you do during a blackout to protect your heating system?

Typically, a power outage will not last excessively long. In these cases, your house will stay warm enough for several hours. However, in the uncommon circumstance of a severe winter storm, where your power is out for an extended period of time, unplug your furnace in the case of a power outage. You should do this in order to ensure that odd surges of power do not damage your furnace, just as you would for your electronics.

What to do if your gas furnace stops working after a power outage

Furnaces can be very temperamental pieces of equipment. If after a power outage your furnace is not working properly, don’t panic. First, make sure that your thermostat is on and that it is set properly. If it is and your furnace is still not working, it may have become damaged during the outage. You can try restarting it but be careful not to cause further damage by messing around with things.

Call your local HVAC professional to help you if your gas furnace is not working after a power outage – chances are it will be a fairly simple fix!

Tips for staying warm

 If you are stuck in a blackout without a functioning heat source, here are some tips for staying warm:

  • Layer up with warm clothes
  • Cuddle up under blankets
  • Sit near other people
  • Use a temporary wood burning stove
  • Use a kerosene heater (as long as you have fuel).
