Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Liberty and the Kansas City Metro Area, but one thing the team at Air Unlimited Heating & Cooling 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 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 a couple of things a homeowner can do before calling in the experts at Air Unlimited Heating & Cooling. Check the Thermostat We have had calls where we simply had to switch a thermostat from “cool” to “heat”. While adjusting the thermostat for the season, a homeowner can easily forget to flip the switch, telling your heating and cooling system what you would like it to do. Another thing to check while you’re at the thermostat is the battery. Most digital thermostats give 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 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 inhibit your system’s efficiency and stifle air flow, it could also cause an abrupt breakdown. Changing the filter in your heating and cooling system is simple 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 look at 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.
