Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t count on the weather in Florissant, but one thing the team at B & B Heating & Cooling wants you to be able to depend on is your heating and cooling system. Having a comfy home isn’t a seasonal thing, it’s something you need all year. When your furnace is having trouble 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, reliable self lately, there are a few things a homeowner can do before calling in the experts at B & B Heating & Cooling. 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 forget to flip 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 give a low battery warning, but if some time has passed since you’ve changed batteries it may be time for a swap. It’s another simple 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 cripple 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 easy and it can play a major 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 down the line. Closed vents cause 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 issues the team at B & B Heating & Cooling are always there for you to make sure all of your home comfort needs are met.
