Common Furnace Problems

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:

Thermostat problems – as it turns out, most furnace problems are actually thermostat problems. If you use a digital or programmable thermostat, check the battery to make sure it’s working properly. If it seems to be, or if you can’t access the battery, you may have to replace the thermostat.
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 – can signify an air leak
  • Rumbling or rattling – can be caused by an out-of-balance blower wheel or simply a dirty furnace

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.
