Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t depend on the weather in Tuscaloosa, but one thing the team at KDM Service Corporation 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 expect all year. When your furnace is having problems 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, stable self lately, there are some things a homeowner can do before calling in the experts at KDM Service Corporation.

Check the Thermostat

We have had calls where the only thing we did was 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 need it to do.

One thing to look over while you’re at the thermostat is the battery. The majority of digital thermostats have 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 troubles. Not only will a dirty filter hinder 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 major 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. Sometimes a problem can be as simple as a tripped breaker or blown fuse.

Check the Vents

A common misconception is that a homeowner should close 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.
