Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

The fluctuating weather in Mechanicsville can mean a host of things, from the changing color of leaves to turning on your furnace for the cooler months. Of course, whole 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 headed for furnace repair though.

When your furnace quits working or you notice it operating oddly, there are a couple things you can check on before calling in the team at M & S Heating & Air LLC 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 easiest checks that homeowners can do on their own, and may solve the problem more than they’d like to admit. Ensure your thermostat is: 

  • Set to “heat”
  • Set higher than the room temperature
  • Utilizing 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 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 change it yourself. Not to mention that a dirty furnace filter lowers your system’s efficiency and reduces airflow.

3) Find and inspect your furnace’s switches

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

  • Near the furnace and typically look like your stereotypical light switch.
  • At your circuit breaker panel. Find 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 switch it back to the On position. 

4) Open all of your vents

A common blunder among homeowners is to close vents in unoccupied 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 shut down because of added airflow pressure.

If you’ve done 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 shout. The pros at M & S Heating & Air LLC in Mechanicsville are here to ensure all of your furnace repair needs are met, so give us a call at 301-363-4699.
