Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

October 07, 2015

The shifting weather in McHenry can mean a host of things, from the changing color of leaves to switching on your furnace for the colder months. Of course, whole 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 headed for furnace repair though.

When your furnace fails to work or you notice it behaving strangely, there are a few things you can check on before calling in the team at Jett's Heating & Air Inc. 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 simplest checks that homeowners can do themselves, and could solve the issue more than they’d like to admit. Ensure your thermostat is: 

  • Set to “heat”
  • Set higher than the room temperature
  • Working with a newer battery

2) Look at the furnace filter 

Dirty filters can cause furnaces to act weirdly, making them shut down without notice and without making a noise. 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 exchange it yourself. Not to mention that a dirty furnace filter decreases your system’s efficiency and reduces airflow.

3) Find and inspect your furnace’s switches

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

  • Around the furnace and usually look like your regular light switch.
  • At your circuit breaker panel. Pinpoint 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 typical blunder among homeowners is to close vents in unused rooms, but this may actually lead to a need for furnace repair. Closing these vents could potentially cause your system to be less efficient and turn off because of added airflow pressure.

If you’ve completed 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 ring.
