Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in West Valley, but one thing the team at Select Comfort System Heating & Air Conditioning wants you to be able to trust in is your heating and cooling system. Having a comfortable home isn’t a seasonal thing, it’s something you need all year. When your furnace is having trouble you may think that means a furnace repair can be expected in your future. That may not be the case. If your furnace hasn’t been its usual, stable self lately, there are a couple of things a homeowner can do before calling in the experts at Select Comfort System Heating & Air Conditioning. Check the Thermostat We have been on a job where all we had to do was switch a thermostat from “cool” to “heat”. While changing the thermostat for the season, it’s easy for a homeowner to forget to flip the switch, telling your heating and cooling system what you need it to do. Something else to check while you’re at the thermostat is the battery. The majority of digital thermostats have a low battery warning, but if it’s been a while since you’ve changed batteries it may be time for a switch. It’s another simple fix that could save you a repair call. Check the Filter A dirty air filter can create all sorts of problems. Not only will a dirty filter inhibit your system’s efficiency and stifle air flow, it could also cause an unexpected breakdown. Changing the filter in your heating and cooling system is effortless and it can play a huge role in keeping your system running at its best. Check the Switches The first switch you’ll want to check is the breaker for your furnace. It’s often the case that a problem can be as simple as a tripped breaker or blown fuse. Check the Vents A common misconception is that a homeowner should shut the vents in unused rooms. This could actually lead to a furnace repair down the line. Closed vents generate higher pressure throughout your duct system and cause your system to work harder than it needs to.
