Reasons Your Furnace Needs to be Repaired

Any furnace you buy these days is most likely going to be very reliable. However, there are a few common furnace problems you may run into with your system:

  • Mismatched thermostat and furnace – some furnaces need specific types of thermostats to activate certain features, otherwise the thermostat might not work properly.
  • Noisy operation – furnaces are supposed to run quietly. Call us today if you hear squeaking, rumbling, or rattling.
  • A blower that does not turn off – the first thing to do here is check to make sure your thermostat is set to AUTO and not ON. If it’s set properly, you may have a blockage in your system or a damaged limit switch.
  • A blower that turns on and off too frequently (short cycling) – short cycling is most commonly caused by a blockage in your system.
  • Furnace not producing enough heat – this is most commonly caused by clogged filters.
  • Furnace not producing any heat – if your furnace isn’t producing any heat, the power could be cut off, the thermostat could be malfunctioning, or the pilot light could be out.
  • Unlit pilot light – a failed thermocouple, strong draft, or clogged gas supply all could cause your pilot light to go out.
