Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t bank on the weather in Dallas, but one thing the team at Tri County Air Care LLC wants you to be able to trust in 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 problems 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 recently, there are a few things a homeowner can do before calling in the experts at Tri County Air Care LLC.

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, it’s easy for a homeowner to forget to flip the switch, telling your heating and cooling system what you want it to do.

Another thing to check while you’re at the thermostat is the battery. Most 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 easy 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 a sudden breakdown. Changing the filter in your heating and cooling system is effortless and it can play a major role in keeping your system running 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 close the vents in unused rooms. This could actually lead to a furnace repair down the line. Closed vents create higher pressure throughout your duct system and cause your system to work harder than it needs to.
