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 switching on your furnace for the season. Of course, complete 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 stops 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 simplest checks that homeowners can do on their own, and might solve the problem more than they’d like to admit. Ensure your thermostat is: 

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

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

  • Around the furnace and usually 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 routine 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 done these four troubleshooting tips and still aren’t having any luck getting your system back up and running, it’s probably time to give us a shout. The pros at M & S Heating & Air LLC in Mechanicsville are here to be sure all of your furnace repair needs are met, so give us a call at 301-363-4699.
