First and foremost, what is short cycling? Short cycling is when a furnace turns on and off too quickly, providing you and your home with little to no warmth. This constant turning on and off of the equipment can also cause greater wear and tear, resulting in more money spent on repairs.

Here are a few common causes of short cycling that you should know about, so you can catch on and fix any issues!

  • The most common cause of short cycling is a dirty air filter. A dirty air filter restricts air from reaching the heat exchanger, which causes the furnace to overheat and shut down. Simply changing an air filter every 30 to 60 days can help avoid this.
  • There’s a right and wrong place for a thermostat! If your thermostat is located near a heat source, such as a television, lamp, or a heat register, it’ll misread the temperature inside the home and shut off the furnace. If you find your thermostat isn’t in an optimal position, contact us for help relocating it.
  • Blocked exhaust vents can cause the furnace to overheat, similarly to how a blocked air filter causes the furnace to short cycle, the hot gases build up in the furnace when vents are blocked causing it to overheat. Having the vents cleared and cleaned by a professional can keep your system running optimally.
  • An oversized furnace isn’t better for your home. An oversized furnace will heat your home too quickly, causing it to shut off once it reaches your set temperature. Then, when your home cools off, the furnace will repeat the cycle. If you have reason to believe your heating system is too big for your home, contact us for assistance!
