Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t count on the weather in Bloomington, but one thing the team at All Seasons Heating & A/C Co wants you to be able to count 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 looming on the horizon. That may not be the case. If your furnace hasn’t been its usual, reliable self lately, there are some things a homeowner can do before calling in the experts at All Seasons Heating & A/C Co. Check the Thermostat We have been on a job where all we had to do was switch a thermostat from “cool” to “heat”. While changing 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. One thing to look over while you’re at the thermostat is the battery. Almost all digital thermostats are equipped with a low battery warning, but if it’s been some time 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 inhibit your system’s efficiency and block 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. Sometimes 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 shut the vents in unused rooms. This could actually lead to a furnace repair in the future. Closed vents generate higher pressure inside your duct system and cause your system to work harder than it needs to.
