Soft Start Kit

Extend the life of your Coleman-Mach air conditioner with our new soft start kit that reduces inrush amperage up to 75% and lessens overall power consumption.

Our innovative soft start kit can be used in new Coleman-Mach air conditioners or retrofitted into existing AC units. A soft start will protect your AC by reducing start-up power surges that can trip breakers. It also lowers the overall power consumption while the AC is running providing more efficient performance with worry-free operation.


The Coleman-Mach soft start kit creates a ramped-up power draw at cycle startup for a smooth progression to running voltage thus eliminating troublesome voltage spikes. A short-cycle protection feature increases the overall life of an air conditioner with a Coleman-Mach soft start by lowering startup stress on the compressor. A continuous-learning feature in the Coleman-Mach soft start allows it to optimize a range of electrical parameters to work with varying load conditions and ensure the motor operates optimally for ambient conditions.
