Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t depend on the weather in San Angelo, but one thing the team at Air-Dynamics Inc 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 require 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, reliable self recently, there are a couple of things a homeowner can do before calling in the experts at Air-Dynamics Inc.

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, a homeowner can easily forget to flip the switch, telling your heating and cooling system what you would like 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 it’s been a while since you’ve changed batteries it may be time for a change. It’s another simple 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 cripple 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 operating at its best.

Check the Switches

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