What is Considered a Furnace Short Cycling?

Short cycling is a common problem with furnaces that can lead to premature failure. It occurs when the furnace turns on and off too frequently, without running long enough to complete a full heating cycle. This can be caused by a number of factors, including:

  • Oversized furnace: A furnace that is too large for the space it is heating will heat the space too quickly, causing the furnace to turn off before it has a chance to run through a full cycle.
  • Dirty air filter: A dirty air filter can restrict airflow, causing the furnace to overheat and shut off prematurely.
  • Faulty thermostat: A faulty thermostat can send incorrect signals to the furnace, causing it to turn on and off too frequently.
  • Electrical problems: Electrical problems, such as loose wires or a faulty control board, can also cause a furnace to short cycle.

Short cycling can lead to a number of problems, including:

  • Increased energy consumption: A furnace that short cycles will use more energy than a furnace that runs properly.
  • Premature failure: Short cycling can put undue stress on the furnace, causing it to fail prematurely.
  • Reduced comfort: A furnace that short cycles will not be able to maintain a consistent temperature, resulting in reduced comfort.
