Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Zelienople, but one thing the team at Knoechel Heating Company 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 expected in your future. That may not be the case. If your furnace hasn’t been its usual, stable self recently, there are some things a homeowner can do before calling in the experts at Knoechel Heating Company. Check the Thermostat We have been on a job where we simply had to switch a thermostat from “cool” to “heat”. While setting 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 look at while you’re at the thermostat is the battery. Most 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 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 complications. Not only will a dirty filter inhibit your system’s efficiency and decrease air flow, it could also cause a sudden breakdown. Changing the filter in your heating and cooling system is easy and it can play a huge role in keeping your system functioning at its best. Check the Switches The first switch you’ll want to check is the breaker for your furnace. Sometimes a problem can be as easy to fix as a tripped breaker or blown fuse. Check the Vents A typical 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 create higher pressure within your duct system and cause your system to work harder than it needs to.
