Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t depend on the weather in Hauppauge, but one thing the team at Cool Power LLC 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 expect all year. When your furnace is having complications you may think that means a furnace repair can be expected in your future. That may not be the case. If your furnace hasn’t been its usual, reliable self lately, there are a couple of things a homeowner can do before calling in the experts at Cool Power LLC . Check the Thermostat We have had calls where all we had to do was switch a thermostat from “cool” to “heat”. While changing 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. Something else to look over 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 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 block air flow, it could also cause a sudden breakdown. Changing the filter in your heating and cooling system is effortless 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 check is the breaker for your furnace. It’s often the case that 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 road. Closed vents create higher pressure throughout your duct system and cause your system to work harder than it needs to. If you’ve tried our troubleshooting tips and you’re still having problems the team at Cool Power LLC are always there for you to make sure all of your home comfort needs are met.
