Here are four things to try yourself before picking up the phone to call us for repairs on your furnace.
1. Check Your Thermostat
The first thing you should do is make sure your thermostat is set properly. Someone might have bumped it or adjusted it without you realizing it. Make sure the thermostat is set to “heat” and on the temperature you want. If the temperature is lower than normal, try bumping it up a couple of degrees to see if that works.
Some thermostats operate on batteries alone while others are hardwired and only use batteries for backup. If your thermostat is battery-operated it might be time to change the batteries.
2. Your Furnace Filter
Have you changed your filter lately? A dirty filter can block airflow to your furnace which will shut it down to prevent overheating. You should be changing your filter every 30-90 days.
3. The Source of Fuel
First - do NOT do any work yourself on gas lines or valves. If you suspect that one of these issues is to blame, call an HVAC professional immediately because doing this kind of work is dangerous to people who are not properly trained.
If you can locate your valve, just make sure that the valve is on and that it is supplying fuel to your furnace in order to run. While we’re at it - do you have the proper amount of fuel in order for your furnace to operate? Maybe you ran out of propane or you forgot to pay the gas bill. Oops!
4. Circuit Breakers
It’s possible that you have blown a fuse. Check your fuse box and locate the one labeled “furnace”. If it’s flipped opposite of the others, switch it back and see if that fixes the problem.
