Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

The changing weather in Perry can mean a number of things, from the changing color of leaves to flipping on your furnace for the season. Of course, total home comfort is your year-round goal, but sometimes our heating and cooling equipment doesn’t feel like cooperating. That doesn’t mean that you’re predestined for furnace repair though.

When your furnace fails to work or you notice it behaving weirdly, there are a few things you can check on before calling in the experts at Gillman Heating and Air for furnace repair. Here are a couple troubleshooting tips to try before giving us a ring. 

1) Check your thermostat

This is one of the most basic checks that homeowners can do independently, and might solve the issue more than they’d like to admit. Ensure your thermostat is: 

  • Set to “heat”
  • Set higher than the room temperature
  • Using a fresh battery

2) Look at the furnace filter 

Dirty filters can cause furnaces to act out of the ordinary, making them shut down without notice and without making a peep. Furnace filters have been the cause for a lot of furnace repair calls in the past, but there’s no reason to pick up the phone when you can change it yourself. Not to mention that a dirty furnace filter lowers your system’s efficiency and inhibits airflow.

3) Find and inspect your furnace’s switches

The majority of the time, switches to your furnace are found:

  • Close to the furnace and usually look like your stereotypical light switch.
  • At your circuit breaker panel. Find the breaker that controls your furnace and find out if it is in the middle position or the Off position. If it is, cycle the breaker to Off and then switch it back to the On position. 

4) Open all of your vents

A routine mistake among homeowners is to close vents in unused rooms, but this may actually lead to a need for furnace repair. Closing these vents may potentially cause your system to be less efficient and stop working because of added airflow pressure.

If you’ve tried these four troubleshooting tips and still aren’t having any luck getting your system back in working order, it’s probably time to give us a call. The pros at Gillman Heating and Air in Perry are here to be sure all of your furnace repair needs are met, so give us a call at 478-202-3076.
