Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

October 07, 2015

The shifting weather in St. Louis can mean a variety 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 doing that. That doesn’t mean that you’re predestined for furnace repair though.

When your furnace fails to work or you notice it acting strangely, there are a few things you can check on before calling in the pros at Morgner Inc. Air Conditioning & Heating for furnace repair. Here are a few 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 independently, and could solve the concern more than they’d like to admit. Ensure 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 noise. Furnace filters have been the cause for many 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 inhibits airflow.

3) Find and inspect your furnace’s switches

Most of the time, switches to your furnace are found:

  • Near the furnace and usually look like your everyday light switch.
  • At your circuit breaker panel. Identify the breaker that controls your furnace and figure out if it is in the middle position or the Off position. If it is, cycle the breaker to Off and then flip it back to the On position. 

4) Open all of your vents

A routine error among homeowners is to close vents in unoccupied rooms, but this could actually lead to a need for furnace repair. Closing these vents can potentially cause your system to be less efficient and turn off 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 Morgner Inc. Air Conditioning & Heating in St. Louis are here to ensure all of your furnace repair needs are met, so give us a call at 314-262-4541.
