Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Pacheco, but one thing the team at Clean Air HVAC wants you to be able to trust in is your heating and cooling system. Having a comfortable 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, stable self lately, there are some things a homeowner can do before calling in the experts at Clean Air HVAC. Check the Thermostat We have been on a job where the only thing we did was switch a thermostat from “cool” to “heat”. While setting the thermostat for the season, a homeowner can easily overlook flipping the switch, telling your heating and cooling system what you want it to do. Something else to look at while you’re at the thermostat is the battery. Almost all digital thermostats give a low battery warning, but if it’s been a while since you’ve changed batteries it may be time for a switch. It’s another simple 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 decrease air flow, it could also cause an unexpected 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. 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 close the vents in unused rooms. This could actually lead to a furnace repair down the line. Closed vents generate higher pressure within your duct system and cause your system to work harder than it needs to.
