Furnace Troubleshooting: What to Do Before Calling for Furnace Repair

You can’t count on the weather in Portland Metro, but one thing the team at Central Air 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 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, dependable self recently, there are some things a homeowner can do before calling in the experts at Central Air Inc.

Check the Thermostat

We have had calls where we simply had to 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 need it to do.

One thing to look at while you’re at the thermostat is the battery. Almost all 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 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 simple and it can play a major role in keeping your system functioning 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 within your duct system and cause your system to work harder than it needs to.
