Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015The changing weather in the Main Line can mean a host of things, from the changing color of leaves to turning on your furnace for the cooler months. Of course, complete 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 automatically destined for furnace repair though. When your furnace fails to work or you notice it behaving weirdly, there are a few things you can check on before calling in the experts at O'Brien Heating & Air Conditioning 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 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” Programmed higher than the room temperature Utilizing 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 peep. 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 exchange it yourself. Not to mention that a dirty furnace filter diminishes your system’s efficiency and inhibits airflow. 3) Find and inspect your furnace’s switches The majority of the time, switches to your furnace are found: Around the furnace and normally look like your stereotypical light switch. At your circuit breaker panel. Identify the breaker that controls your furnace and figure out if it is in the middle position or the Off position. If it is, cycle the breaker to Off and then flip it back to the On position. 4) Open all of your vents A common mistake among homeowners is to close vents in unused rooms, but this could actually lead to a need for furnace repair. Closing these vents may 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 in working order, it’s probably time to give us a ring.
