Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t count on the weather in Denver, but one thing the team at Northglenn Heating & Air Conditioning, Inc. 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 need all year. When your furnace is having trouble you may think that means a furnace repair can be needed soon. That may not be the case. If your furnace hasn’t been its usual, dependable self recently, there are some things a homeowner can do before calling in the experts at Northglenn Heating & Air Conditioning, Inc..

Check the Thermostat

We have received calls where we simply had to switch a thermostat from “cool” to “heat”. While setting 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 need it to do.

Another thing to check while you’re at the thermostat is the battery. The majority of digital thermostats are equipped with 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 simple 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 stifle air flow, it could also cause an unexpected breakdown. Changing the filter in your heating and cooling system is effortless and it can play a big role in keeping your system running 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 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 create higher pressure within your duct system and cause your system to work harder than it needs to.
