When your furnace stops working in the middle of the night, you want to do whatever you can in order to get it up and running again. There are things that you can do that might be able to get your furnace back up and running without having to call a heating contractor so that they can come out and fix your furnace. If you do a little bit of troubleshooting, you can make it easier on yourself if you do have to have a contractor come out. You can tell them the things that you did check, so they know that they won't have to check those out.
If your furnace runs on heating oil or something like natural gas, you want to make sure that you have fuel and that it is getting from the fuel source to your furnace. If you have a tank for heating oil, then you need to go check your tank. There should be a meter somewhere on your tank that will let you see how much fuel you have in there. It may not give you a precise reading, but you should be able to get a pretty good idea as to how much fuel is in the tank. If it is empty, then you need to call and have some fuel delivered to get your heater back on.
You also need to make sure that your furnace is getting power. It needs power to push the heat through blowers or radiators. It also may need to have power to act as a pilot light. That pilot light will light the burner to make sure that the furnace can burn the necessary fuel to provide heat. There are a couple of places you can check to make sure that you have power to your furnace. The first place to check is at your circuit breaker or fuse box. You need to make sure that the fuse or circuit breaker are in the on position. If the fuse is burned out or the circuit breaker has flipped off, then there is no power getting to your furnace. Reset them and you will be ready to go. If they flip back off, then you need to leave them alone until you get a professional out to look at your house.
If you have done everything you can, but your furnace still isn't working, then you definitely need to call a contractor to come and look at your furnace to fix it. Look in your area for a contractor like Edwards Heating & Air Conditioning LLC to find out more.
