A hard start device helps boost your compressor during start-up. The average unit will start up 30-50% faster when you add the CSR-U1 exact equivalent part by PartsBroz. Why does this matter? During start-up, your AC unit uses five to ten times more power than it does when it’s running. Overtime, the heat produced during start-up damages the compressor, capacitor, and terminals, reducing the product life of your AC unit. The faster your unit starts up, the less damage will be done, and the longer your unit will last.
The CSR-U1 exact equivalent part by PartsBroz works with 1- to 3-ton AC units. Larger units require a larger capacitor.
