Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Aurora, but one thing the team at Service Plus Mechanical wants you to be able to trust in is your heating and cooling system. Having a cozy home isn’t a seasonal thing, it’s something you need 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, reliable self recently, there are a couple of things a homeowner can do before calling in the experts at Service Plus Mechanical. Check the Thermostat We have been on a job where all we had to do was switch a thermostat from “cool” to “heat”. While setting the thermostat for the season, a homeowner can easily overlook flipping the switch, telling your heating and cooling system what you need it to do. Something else to look over while you’re at the thermostat is the battery. The majority of digital thermostats are equipped with a low battery warning, but if it’s been a while 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 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 simple and it can play a big 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. Sometimes 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 in the future. Closed vents cause higher pressure throughout your duct system and cause your system to work harder than it needs to.
