Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t bank on the weather in Middletown, but one thing the team at Schagrin Gas Company 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 require all year. When your furnace is having problems 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 a couple of things a homeowner can do before calling in the experts at Schagrin Gas Company. Check the Thermostat We have been on a job where the only thing we did was switch a thermostat from “cool” to “heat”. While setting 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. Another thing to check while you’re at the thermostat is the battery. Almost all digital thermostats give 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 simple 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 inhibit your system’s efficiency and stifle air flow, it could also cause a sudden 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 check is the breaker for your furnace. It’s often the case that 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 seal the vents in unused rooms. This could actually lead to a furnace repair in the future. Closed vents generate higher pressure throughout your duct system and cause your system to work harder than it needs to.
