Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t count on the weather in Humble, but one thing the team at Air Houston Mechanical LLC wants you to be able to count 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 complications 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, dependable self as of late, there are some things a homeowner can do before calling in the experts at Air Houston Mechanical LLC.

Check the Thermostat

We have been on a job where the only thing we did was switch a thermostat from “cool” to “heat”. While adjusting 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 at 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 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 problems. Not only will a dirty filter cripple 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 simple and it can play a big role in keeping your system running 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 easy to fix as a tripped breaker or blown fuse.

Check the Vents

A typical misconception is that a homeowner should shut the vents in unused rooms. This could actually lead to a furnace repair in the future. Closed vents cause higher pressure inside your duct system and cause your system to work harder than it needs to.
