It’s a question we receive all the time: will a gas furnace work without electricity? It won’t, and there are a few reasons why.
Before we delve into the three main components of your furnace that require electricity, we want to make it clear that if you’re experiencing any problem with your furnace’s electrical system, do not try to repair it on your own.
Without the proper knowledge, safety equipment, and experience, it’s extremely dangerous to toy with electrical wiring and components on your own. Now let’s talk about where your furnace receives and uses electricity.
We all expect our heaters to provide us with the heat we desire, especially during the winter season. Fairfield temperatures are quite brisk this time of year, so it’s best that you prepare, as we have a long winter ahead of us. One way to do this is by taking the time to think about your air filter. Air filters need regular changing to keep your furnace running efficiently. They need to be changed more than just once a year by a trained HVAC technician.
Maybe. We apologize if that is not quite as satisfactory of an answer as you were hoping for, but it is the best we can give right off the bat.

Here is a common scenario that happens in the modern home. You notice that the heater has not cycled on in quite some time. The air is getting chilly, so you go to the thermostat. You try turning it a few degrees warmer, but nothing happens. You call out to your spouse, or say to yourself, “I think the thermostat is busted!”
The hum of your heating system as it starts its cycle as usual is, of course, nothing to be alarmed about. You know the normal noises your heating system makes, which means you know when something is off. Typically, a sound from your heating system may not mean that your system is in any immediate danger, but it often still means you should call in technicians ASAP.
As winter draws near, there are a lot of things to concern yourself with around the house. Winterizing the home means covering windows, filling up air leaks and tackling drafts, packing up the garden hose and winterizing the outdoor faucets, and insulating wherever you can. It means checking the storm drains again, inspecting the fireplace and chimney, and digging winter décor and blankets out of storage.
