Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

October 07, 2015

The fluctuating weather in Anchorage can mean a number of things, from the changing color of leaves to flipping on your furnace for the colder months. 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 predestined for furnace repair though.

When your furnace fails to work or you notice it acting weirdly, there are four things you can check on before calling in the experts at Discount Mechanical Heating & Plumbing Services for furnace repair. Here are a few troubleshooting tips to try before giving us a shout. 

1) Check your thermostat

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

  • Set to “heat”
  • Set higher than the room temperature
  • Using 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 sound. Furnace filters have been the cause for quite a few 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 diminishes 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 usually look like your everyday 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 common blunder among homeowners is to close vents in vacant rooms, but this might actually lead to a need for furnace repair. Closing these vents may potentially cause your system to be less efficient and shut down because of added airflow pressure.

If you’ve completed 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 ring.
