Adding the CSR-U2 exact equivalent part by PartsBroz to your AC unit can speed up start-up speeds by 30 to 50%. The faster your AC unit starts up, the longer your unit will last. Why's that? During start-up, your AC uses five to ten times more power than it does when it's running. Overtime, the heat produced during start-up damages the unit's compressor, capacity, and terminals, reducing the life expectancy of your AC unit. A hard start device will keep your AC unit running for as long as possible.

The CSR-U2 exact equivalent part by PartsBroz works with 3.5 to 5 ton AC units. Smaller units require a smaller capacitor.

Quick Fix that Improves AC Start-Up

Adding a hard start device to your air conditioner or compressor is a good idea if:

  • Your AC unit makes a lot of noise during start up
  • House lights flicker during AC start up
  • Your AC unit takes a while to start up
  • You want to extend the life of your AC unit
  • You want to reduce your home's energy consumption
