Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t count on the weather in South Beloit and Belvidere, but one thing the team at Fleming Heating & Air Conditioning 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 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, dependable self lately, there are a couple of things a homeowner can do before calling in the experts at Fleming Heating & Air Conditioning Inc.. Check the Thermostat We have received calls where the only thing we did was 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 would like it to do. One thing to look over while you’re at the thermostat is the battery. Most digital thermostats have 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 painless 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 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 look at is the breaker for your furnace. Occasionally 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 down the line. Closed vents generate higher pressure within your duct system and cause your system to work harder than it needs to.
