Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Keokuk, but one thing the team at WM J Kraus & Son wants you to be able to trust in is your heating and cooling system. Having a comfy 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, reliable self recently, there are a couple of things a homeowner can do before calling in the experts at WM J Kraus & Son. Check the Thermostat We have had calls where we simply had to switch a thermostat from “cool” to “heat”. While changing 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 want it to do. Something else to check while you’re at the thermostat is the battery. Most digital thermostats give a low battery warning, but if it’s been a while since you’ve changed batteries it may be time for a change. 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 big role in keeping your system functioning at its best. Check the Switches The first switch you’ll want to investigate 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 create higher pressure within your duct system and cause your system to work harder than it needs to. If you’ve tried our troubleshooting tips and you’re still having problems the team at WM J Kraus & Son are always there for you to make sure all of your home comfort needs are met.
