How To Troubleshoot Your Furnace

There’s nothing worse than waking up on a winter day to a home that feels as cold inside as the temperature outside! If this is a situation you’ve found yourself in, an improperly functioning furnace could be what’s causing your chilly mornings. While it is important to call an HVAC professional right away if you smell gas or hear strange noises coming from your furnace, in some cases the problem may be minor and you might be able to do some furnace troubleshooting. Here’s our list of four furnace troubleshooting solutions that are safe for you to attempt before calling a professional.

  1. Make Sure The Thermostat is Set Properly

Check that your thermostat is set on “heat” and the temperature is positioned where you want it. Perhaps someone in your home turned down the thermostat or the switch accidentally got flipped. If the thermostat is set properly, turn it up a few degrees to see if you notice a difference or your system kicks on.

  1. Replace Your Furnace Filter

Dirty filters can affect the air quality in your home and can shut off your furnace, especially new gas furnaces. Furnace filters should be changed every month to three months to allow for proper airflow.

  1. Check Circuit Breakers

Check your circuit breakers to see if you may have possibly blown a fuse. Locate your fuse box, and look for the switch marked “furnace”. Leave the switch off for 30-60 seconds and turn the switch back on. If your issue is not remedied, it’s time to call JD!

  1. Change The Thermostat Batteries

If you have a battery-powered thermostat, make sure that the batteries aren’t running low or are dead. If they are dead, the thermostat won’t be able to communicate with the furnace.

If the furnace troubleshooting checklist did not alleviate your issue and you’re hearing weird noises or smells coming from your furnace, call the team at JD Service Now TODAY at (919) 238-6914!
