The Top Reasons Why a Furnace Will Short Cycle

One of the most common issues that homeowners experience while trying to warm their home is a short-cycling furnace (overheating). Short cycling is the act of a furnace turning on and off frequently with minimal amounts of time between the switching. What does short cycling mean for a furnace’s performance? When the system begins to short cycle, it is common for systems to produce little to no heat before shutting down.
