Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t count on the weather in Saint Louis, but one thing the team at Morgner Incorporated Air Conditioning & Heating wants you to be able to trust in is your heating and cooling system. Having a comfortable home isn’t a seasonal thing, it’s something you expect all year. When your furnace is having trouble you may think that means a furnace repair can be looming on the horizon. 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 Morgner Incorporated Air Conditioning & Heating. 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 overlook flipping the switch, telling your heating and cooling system what you would like it to do. Something else to look over 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 troubles. Not only will a dirty filter hinder your system’s efficiency and decrease air flow, it could also cause an unexpected breakdown. Changing the filter in your heating and cooling system is effortless 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 check 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 create higher pressure throughout your duct system and cause your system to work harder than it needs to.
