When a furnace is in good working condition, it will turn on, run for awhile, and then turn off when the temperature inside the home has reached the set temperature. Unfortunately, a furnace can develop problems as it ages, and one of those issues is short cycling. Short cycling is when a furnace turns on, runs for a couple of minutes, and then turns off. In most cases, a furnace that is in need of repair will short cycle multiple times an hour.
