Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Wharton, but one thing the team at Faust Air Conditioning and Heating 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 looming on the horizon. That may not be the case. If your furnace hasn’t been its usual, reliable self lately, there are a few things a homeowner can do before calling in the experts at Faust Air Conditioning and Heating. Check the Thermostat We have received 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 want it to do. One thing to check while you’re at the thermostat is the battery. Most 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 hinder your system’s efficiency and stifle air flow, it could also cause an abrupt breakdown. Changing the filter in your heating and cooling system is simple and it can play a big role in keeping your system operating at its best. Check the Switches The first switch you’ll want to look at is the breaker for your furnace. Occasionally a problem can be as simple as a tripped breaker or blown fuse. Check the Vents A common misconception is that a homeowner should shut 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. If you’ve been through our troubleshooting tips and you’re still having troubles the team at Faust Air Conditioning and Heating are always there for you to make sure all of your home comfort needs are met.
