You can’t depend on the weather in Manassas, but one thing the team at Twin Air LLC 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 require all year. When your furnace is having complications you may think that means a furnace repair can be expected in your future. That may not be the case. If your furnace hasn’t been its usual, stable self as of late, there are some things a homeowner can do before calling in the experts at Twin Air 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 setting the thermostat for the season, a homeowner can easily overlook flipping the switch, telling your heating and cooling system what you need it to do.

Something else to check while you’re at the thermostat is the battery. Almost all digital thermostats have a low battery warning, but if some time has passed since you’ve changed batteries it may be time for a change. 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 block air flow, it could also cause a sudden breakdown. Changing the filter in your heating and cooling system is simple and it can play a huge 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 simple as a tripped breaker or blown fuse.

Check the Vents

A common misconception is that a homeowner should seal the vents in unused rooms. This could actually lead to a furnace repair down the line. Closed vents generate higher pressure throughout your duct system and cause your system to work harder than it needs to.
