Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t bank on the weather in Erie, but one thing the team at Patterson & Stirling Inc 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 require all year. When your furnace is having problems you may think that means a furnace repair can be looming on the horizon. That may not be the case. If your furnace hasn’t been its usual, reliable self as of late, there are a couple of things a homeowner can do before calling in the experts at Patterson & Stirling Inc. Check the Thermostat We have had calls where we simply had to 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 would like it to do. Another thing to look at while you’re at the thermostat is the battery. The majority of digital thermostats have a low battery warning, but if some time has passed since you’ve changed batteries it may be time for a swap. It’s another easy 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 operating at its best. Check the Switches The first switch you’ll want to investigate 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 seal the vents in unused rooms. This could actually lead to a furnace repair down the road. Closed vents cause higher pressure within your duct system and cause your system to work harder than it needs to.
