Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t count on the weather in Williamsport, but one thing the team at Lycoming Heating Company wants you to be able to trust in is your heating and cooling system. Having a cozy 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, dependable self lately, there are a couple of things a homeowner can do before calling in the experts at Lycoming Heating Company. Check the Thermostat We have had calls where we simply had to 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. One thing to check 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 swap. It’s another painless 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 hinder 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 effortless and it can play a huge role in keeping your system functioning at its best. Check the Switches The first switch you’ll want to check is the breaker for your furnace. Occasionally a problem can be as minor as a tripped breaker or blown fuse. Check the Vents A frequent misconception is that a homeowner should seal the vents in unused rooms. This could actually lead to a furnace repair in the future. Closed vents cause higher pressure throughout 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 issues the team at Lycoming Heating Company are always there for you to make sure all of your home comfort needs are met.
