Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Greenville, but one thing the team at Ken Parker Service Inc wants you to be able to depend on 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 looming on the horizon. That may not be the case. If your furnace hasn’t been its usual, stable self lately, there are some things a homeowner can do before calling in the experts at Ken Parker Service Inc. Check the Thermostat We have had calls where we simply had to switch a thermostat from “cool” to “heat”. While setting 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. 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 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 troubles. Not only will a dirty filter hinder 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 major role in keeping your system operating 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 seal the vents in unused rooms. This could actually lead to a furnace repair down the line. Closed vents cause higher pressure inside your duct system and cause your system to work harder than it needs to.
