Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

The shifting weather in Waterloo can mean a number of things, from the changing color of leaves to switching on your furnace for the cooler months. 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 oddly, there are a couple things you can check on before calling in the experts at Cronin-Verheul Heating & A/C Ltd for furnace repair. Here are four troubleshooting tips to try before giving us a call. 

1) Check your thermostat

This is one of the most basic checks that homeowners can do on their own, and may solve the issue more than they’d like to admit. Make sure your thermostat is: 

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

2) Look at the furnace filter 

Dirty filters can cause furnaces to act erratically, 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 swap it out yourself. Not to mention that a dirty furnace filter lowers your system’s efficiency and harms airflow.

3) Find and inspect your furnace’s switches

Nearly all of the time, switches to your furnace are found:

  • Close to the furnace and typically look like your regular light switch.
  • At your circuit breaker panel. Identify the breaker that controls your furnace and determine if it is in the middle position or the Off position. If it is, cycle the breaker to Off and then re-set it back to the On position. 

4) Open all of your vents

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

If you’ve tried these four troubleshooting tips and still aren’t having any luck getting your system back operating, it’s probably time to give us a call. The experts at Cronin-Verheul Heating & A/C Ltd in Waterloo are here to make sure all of your furnace repair needs are met, so give us a call at 519-664-0600.
