Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

October 07, 2015

The shifting weather in Suffolk/Nassau County can mean a host of things, from the changing color of leaves to turning 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 helping us out. 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 Airmax Long Island Inc for furnace repair. Here are a couple 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 themselves, and might solve the issue more than they’d like to admit. Be sure your thermostat is: 

  • Set to “heat”
  • Programmed higher than the room temperature
  • Utilizing a new 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 peep. 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 harms airflow.

3) Find and inspect your furnace’s switches

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

  • Around the furnace and normally look like your everyday light switch.
  • At your circuit breaker panel. Find the breaker that controls your furnace and find out 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 error among homeowners is to close vents in unoccupied rooms, but this could 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 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 ring.
