Why HVAC pros use Compressor Saver kits
When a compressor struggles to start, it can pull excessive amperage, trip breakers, and create repeat service calls. Five Two One® Compressor Saver hard start kits are designed to provide additional starting torque and support reliable starts— especially on systems with aging compressors, long line sets, low voltage events, or tough starting conditions.
These kits are commonly used to reduce hard-start symptoms and help extend compressor life by lowering stress during startup. For best results, always verify the root cause (capacitor health, contactor, voltage, refrigerant charge, and mechanical condition).

Five Two One Compressor Saver — FAQs
When should I add a hard start kit?
Hard start kits are commonly used when a compressor struggles to start, draws high amperage on startup, or trips breakers—especially on older systems.
Will it fix every hard-start issue?
A hard start kit can help, but you should also verify voltage, run capacitor health, contactor condition, and compressor mechanical issues.
What information do you need to pick the right kit?
Share system tonnage, voltage, compressor model if available, and the symptoms you’re seeing (slow start, trips, hard-start noise).
