Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Bossier City, but one thing the team at Brooks Heating and Air Conditioning wants you to be able to depend on is your heating and cooling system. Having a comfortable home isn’t a seasonal thing, it’s something you require all year. When your furnace is having trouble 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, dependable self recently, there are some things a homeowner can do before calling in the experts at Brooks Heating and Air Conditioning. Check the Thermostat We have received calls where all we had to do was switch a thermostat from “cool” to “heat”. While setting the thermostat for the season, a homeowner can easily forget to flip the switch, telling your heating and cooling system what you would like it to do. Another thing to look at while you’re at the thermostat is the battery. Most digital thermostats are equipped with a low battery warning, but if some time has passed 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 complications. 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 major role in keeping your system running at its best. Check the Switches The first switch you’ll want to look at 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 road. Closed vents create higher pressure within your duct system and cause your system to work harder than it needs to. If you’ve tried our troubleshooting tips and you’re still having problems the team at Brooks Heating and Air Conditioning are always there for you to make sure all of your home comfort needs are met.
