Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Madera, but one thing the team at Brian’s Heating & Cooling, Inc. wants you to be able to count on is your heating and cooling system. Having a comfy home isn’t a seasonal thing, it’s something you expect all year. When your furnace is having trouble 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, dependable self recently, there are a couple of things a homeowner can do before calling in the experts at Brian’s Heating & Cooling, Inc.. Check the Thermostat We have received calls where all we had to do was switch a thermostat from “cool” to “heat”. While changing the thermostat for the season, a homeowner can easily overlook flipping the switch, telling your heating and cooling system what you need it to do. Another thing to look over while you’re at the thermostat is the battery. The majority of digital thermostats give 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 simple fix that could save you a repair call. Check the Filter A dirty air filter can create all sorts of troubles. 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 easy 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 seal the vents in unused rooms. This could actually lead to a furnace repair down the road. Closed vents cause higher pressure throughout your duct system and cause your system to work harder than it needs to.
