Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t bank on the weather in Lexington, but one thing the team at James Heating & A/C, Inc wants you to be able to depend on is your heating and cooling system. Having a comfy home isn’t a seasonal thing, it’s something you require all year. When your furnace is having trouble 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, dependable self recently, there are a few things a homeowner can do before calling in the experts at James Heating & A/C, Inc.

Check the Thermostat

We have had calls where the only thing we did was switch a thermostat from “cool” to “heat”. While setting the thermostat for the season, a homeowner can easily overlook flipping the switch, telling your heating and cooling system what you want it to do.

One 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 a while since you’ve changed batteries it may be time for a change. It’s another painless 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 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 easy 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 check is the breaker for your furnace. Sometimes a problem can be as minor as a tripped breaker or blown fuse.

Check the Vents

A frequent misconception is that a homeowner should shut 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.
