Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t bank on the weather in Longview, but one thing the team at Ben Maines Air Conditioning, Inc. wants you to be able to depend on is your heating and cooling system. Having a cozy home isn’t a seasonal thing, it’s something you expect all year. When your furnace is having complications 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, stable self as of late, there are some things a homeowner can do before calling in the experts at Ben Maines Air Conditioning, 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 forget to flip the switch, telling your heating and cooling system what you want it to do. Something else to check while you’re at the thermostat is the battery. Almost all digital thermostats have a low battery warning, but if some time has passed since you’ve changed batteries it may be time for a switch. It’s another simple 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 decrease 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 big role in keeping your system running at its best. Check the Switches The first switch you’ll want to look at is the breaker for your furnace. Occasionally 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 shut the vents in unused rooms. This could actually lead to a furnace repair down the road. Closed vents create higher pressure inside your duct system and cause your system to work harder than it needs to.
