Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Colorado Springs, but one thing the team at Mitchell Heating 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 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 as of late, there are a few things a homeowner can do before calling in the experts at Mitchell Heating. Check the Thermostat We have had calls 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 need it to do. One thing to look at while you’re at the thermostat is the battery. Most digital thermostats give a low battery warning, but if it’s been some time 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 troubles. Not only will a dirty filter inhibit your system’s efficiency and stifle air flow, it could also cause an unexpected 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 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 shut the vents in unused rooms. This could actually lead to a furnace repair down the line. Closed vents generate higher pressure within your duct system and cause your system to work harder than it needs to. If you’ve gone through our troubleshooting tips and you’re still having troubles the team at Mitchell Heating are always there for you to make sure all of your home comfort needs are met.
