Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t count on the weather in Plainfield, but one thing the team at PWA Heating & Cooling Inc wants you to be able to trust in is your heating and cooling system. Having a comfy 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 needed soon. 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 PWA Heating & Cooling Inc. Check the Thermostat We have received calls where we simply had to switch a thermostat from “cool” to “heat”. While adjusting the thermostat for the season, a homeowner can easily overlook flipping the switch, telling your heating and cooling system what you would like it to do. Something else to check while you’re at the thermostat is the battery. The majority of digital thermostats are equipped with a low battery warning, but if some time has passed since you’ve changed batteries it may be time for a change. 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 cripple your system’s efficiency and block air flow, it could also cause an abrupt breakdown. Changing the filter in your heating and cooling system is effortless and it can play a major 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 minor as a tripped breaker or blown fuse. Check the Vents A frequent misconception is that a homeowner should shut the vents in unused rooms. This could actually lead to a furnace repair in the future. Closed vents create higher pressure inside your duct system and cause your system to work harder than it needs to. If you’ve gone through our troubleshooting tips and you’re still having troubles the team at PWA Heating & Cooling Inc are always there for you to make sure all of your home comfort needs are met.
