Furnace Troubleshooting: What to Do Before Calling for Furnace Repair10/07/2015 You can’t bank on the weather in Midlothian, but one thing the team at Daniel's Heating & Refrigeration Corp. 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 require all year. When your furnace is having problems you may think that means a furnace repair can be looming on the horizon. 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 Daniel's Heating & Refrigeration Corp.. Check the Thermostat We have had calls where all we had to do was switch a thermostat from “cool” to “heat”. While setting the thermostat for the season, it’s easy for a homeowner to forget to flip the switch, telling your heating and cooling system what you need it to do. Another thing to look at while you’re at the thermostat is the battery. Almost all digital thermostats are equipped with 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 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 check is the breaker for your furnace. Occasionally 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 generate higher pressure within your duct system and cause your system to work harder than it needs to.
