Having your furnace break down in Mebane, NC, can be both uncomfortable and dangerous. Fortunately, if you know the most common causes of furnace breakdowns, you might be able to avoid them in the future. Here are three common heating system problems.
1. Faulty Thermostat
You might not expect something as simple as your thermostat to break, but they can and do. Thermostats can run out of batteries or have their wires damaged. In these cases, the thermostat won’t send a signal to the furnace to turn on or off.
Thermostats also can lose their calibration. You might have the thermostat set on 72, but your furnace won’t turn on until your house hits 67 or 77, for example. Thermostat calibration is a more difficult fix than changing batteries; call a professional HVAC technician.
2. Bad Pilot Light or Ignition Control
If your furnace runs on gas, it must be able to ignite the gas to make heat. In the past, having the pilot light go out was a DIY fix, but with today’s sealed electronic ignition control furnaces, it’s better to call someone. A pilot light problem might be because your furnace is dirty, something that routine maintenance can prevent.
3. Lack of Routine Maintenance
Your furnace isn’t meant to run forever without routine maintenance and cleaning. Dust and dirt build up over time on the crucial parts of the furnace and can cause those parts to fail prematurely if left there.
Scheduling furnace maintenance every year before the peak of the heating season can keep your furnace running for years. Don’t count on your warranty to bail you out in case of a breakdown. Many manufacturers require you to keep up with routine maintenance.
