Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t count on the weather in Hendersonville, but one thing the team at Superior Comfort Systems wants you to be able to count on is your heating and cooling system. Having a comfy 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 as of late, there are a few things a homeowner can do before calling in the experts at Superior Comfort Systems.

Check the Thermostat

We have been on a job where all we had to do was switch a thermostat from “cool” to “heat”. While adjusting the thermostat for the season, a homeowner can easily forget to flip the switch, telling your heating and cooling system what you want 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 a while since you’ve changed batteries it may be time for a swap. It’s another easy 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 block 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 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 create higher pressure throughout your duct system and cause your system to work harder than it needs to.
