Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015The shifting weather in Manassas can mean a variety of things, from the changing color of leaves to flipping 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 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 operating weirdly, there are four things you can check on before calling in the experts at Twin Air LLC for furnace repair. Here are a few 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 on their own, and could solve the concern more than they’d like to admit. Be sure your thermostat is: Set to “heat” Turned up higher than the room temperature Using a newer 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 sound. 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 reduces airflow. 3) Find and inspect your furnace’s switches Most of the time, switches to your furnace are found: Close to the furnace and normally look like your regular 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 flip 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 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 completed 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.
