Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t count on the weather in Bishop, but one thing the team at Bishop Heating & Air Conditioning 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 complications 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, stable self recently, there are a few things a homeowner can do before calling in the experts at Bishop Heating & Air Conditioning. Check the Thermostat We have received calls where we simply had to switch a thermostat from “cool” to “heat”. While adjusting 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. One thing to look over while you’re at the thermostat is the battery. The majority of 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 painless 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 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 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. It’s often the case that 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 inside your duct system and cause your system to work harder than it needs to. If you’ve gone through our troubleshooting tips and you’re still having problems the team at Bishop Heating & Air Conditioning are always there for you to make sure all of your home comfort needs are met.
