Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t bank on the weather in Augusta, but one thing the team at McCune Heating & Cooling 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 trouble 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 lately, there are some things a homeowner can do before calling in the experts at McCune Heating & Cooling. Check the Thermostat We have received calls where all we had to do was switch a thermostat from “cool” to “heat”. While adjusting the thermostat for the season, a homeowner can easily overlook flipping the switch, telling your heating and cooling system what you want it to do. Another thing to look over while you’re at the thermostat is the battery. Most digital thermostats give a low battery warning, but if it’s been a while 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 an abrupt breakdown. Changing the filter in your heating and cooling system is easy 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 shut the vents in unused rooms. This could actually lead to a furnace repair down the line. Closed vents cause higher pressure within your duct system and cause your system to work harder than it needs to.
