How Often Should a Heat Pump Cycle?
-
Typical Behavior
-
A heat pump should typically cycle approximately three times per hour at a temperature of 95 to 105 degrees. These run cycles will last for extended periods of time due to the relatively low heat generated. This is in contrast to gas heat, which may cycle more frequently at higher temperatures for shorter duration.

Heat Pump Troubles
-
According to Dan Vandervort's Home Tips, a faulty thermostat may cause the heat pump to cycle on and off more frequently. The problem may also be created by "a clogged filter or blower that is malfunctioning," causing the unit to overheat. If replacing the filter doesn't fix the problem, then it may be necessary to call a professional technician.
Bottom Line
-
A heat pump should typically cycle three times per hour. If the unit cycles more frequently, there may be an issue with your device requiring repair or replacement.
