Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t count on the weather in Olathe, but one thing the team at Polestar Plumbing, Heating & Air Conditioning wants you to be able to depend 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 trouble 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 few things a homeowner can do before calling in the experts at Polestar Plumbing, Heating & Air Conditioning.

Check the Thermostat

We have received calls 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 would like it to do.

Something else to look over while you’re at the thermostat is the battery. Almost all 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 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 troubles. Not only will a dirty filter cripple your system’s efficiency and block air flow, it could also cause a sudden breakdown. Changing the filter in your heating and cooling system is effortless 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 check is the breaker for your furnace. Occasionally a problem can be as minor as a tripped breaker or blown fuse.

Check the Vents

A frequent 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.
