Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t bank on the weather in Scottsboro, but one thing the team at Southern Heating & Cooling Inc. wants you to be able to count on is your heating and cooling system. Having a comfy home isn’t a seasonal thing, it’s something you expect all year. When your furnace is having problems 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 lately, there are some things a homeowner can do before calling in the experts at Southern Heating & Cooling Inc.. Check the Thermostat We have had calls where all we had to do was switch a thermostat from “cool” to “heat”. While changing 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. Another thing to look at while you’re at the thermostat is the battery. Most digital thermostats give a low battery warning, but if it’s been some time since you’ve changed batteries it may be time for a switch. 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 cripple 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 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 investigate 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 seal the vents in unused rooms. This could actually lead to a furnace repair down the road. Closed vents create higher pressure throughout your duct system and cause your system to work harder than it needs to.
