Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t count on the weather in Cedar Rapids, but one thing the team at Ilten's Incorporated wants you to be able to count 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 problems 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 a couple of things a homeowner can do before calling in the experts at Ilten's Incorporated. Check the Thermostat We have had calls where all we had to do was switch a thermostat from “cool” to “heat”. While adjusting the thermostat for the season, it’s easy for a homeowner to forget to flip the switch, telling your heating and cooling system what you would like it to do. Another thing 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 some time has passed 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 huge role in keeping your system running at its best. Check the Switches The first switch you’ll want to look at is the breaker for your furnace. Occasionally a problem can be as simple as a tripped breaker or blown fuse. Check the Vents A common 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 throughout your duct system and cause your system to work harder than it needs to. If you’ve been through our troubleshooting tips and you’re still having issues the team at Ilten's Incorporated are always there for you to make sure all of your home comfort needs are met.
