Hard Start Kits

This category features commercial-grade hard start kits and torque multipliers engineered to provide the essential electrical boost required for HVAC and refrigeration compressors struggling to start under high head pressures or low voltage conditions. Consisting of a heavy-duty start capacitor paired with a precision solid-state or potential relay, these technical components temporarily increase the compressor's starting torque by up to 500%. By drastically reducing the duration of destructive inrush current (LRA) and minimizing electrical strain on the motor windings, these kits prevent circuit breaker tripping, eliminate compressor humming, and protect internal components from premature thermal failure. Indispensable for older systems or long-line refrigeration sets, these professional-grade kits provide HVAC technicians and facility maintenance teams with reliable, code-compliant solutions to extend compressor service life and ensure consistent startup reliability.
