Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

The shifting weather in Suffolk/Nassau County can mean a host of things, from the changing color of leaves to switching 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 cooperating. That doesn’t mean that you’re predestined for furnace repair though.

When your furnace fails to work or you notice it behaving strangely, there are a couple things you can check on before calling in the experts 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 may solve the issue more than they’d like to admit. Be sure your thermostat is: 

  • Set to “heat”
  • Programmed higher than the room temperature
  • Working with a new 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 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 common error among homeowners is to close vents in unused 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 ring. The pros at Airmax Long Island Inc in Suffolk/Nassau County are here to be sure all of your furnace repair needs are met, so give us a call at 631-737-5566.
