Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t count on the weather in Baltimore, but one thing the team at Quality Refrigeration wants you to be able to trust in 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 problems 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 lately, there are a few things a homeowner can do before calling in the experts at Quality Refrigeration.

Check the Thermostat

We have received calls where we simply had to switch a thermostat from “cool” to “heat”. While adjusting the thermostat for the season, a homeowner can easily forget to flip the switch, telling your heating and cooling system what you need it to do.

One thing to check while you’re at the thermostat is the battery. The majority of digital thermostats give a low battery warning, but if some time has passed 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 problems. Not only will a dirty filter inhibit your system’s efficiency and stifle air flow, it could also cause an abrupt 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 check 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 shut the vents in unused rooms. This could actually lead to a furnace repair down the road. Closed vents cause higher pressure within your duct system and cause your system to work harder than it needs to.
