Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t count on the weather in Hattiesburg, but one thing the team at Oak Grove 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 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, stable self recently, there are some things a homeowner can do before calling in the experts at Oak Grove Heating & Air Conditioning.

Check the Thermostat

We have had calls 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 overlook flipping the switch, telling your heating and cooling system what you would like it to do.

Something else to check while you’re at the thermostat is the battery. Most digital thermostats have a low battery warning, but if it’s been a while since you’ve changed batteries it may be time for a switch. It’s another simple fix that could save you a repair call.

Check the Filter

A dirty air filter can create all sorts of problems. Not only will a dirty filter hinder your system’s efficiency and stifle 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 huge role in keeping your system functioning at its best.

Check the Switches

The first switch you’ll want to investigate 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 close the vents in unused rooms. This could actually lead to a furnace repair down the road. Closed vents create higher pressure inside your duct system and cause your system to work harder than it needs to.
