Details:
This is due to the huge current that rushes in when a switch thrown and power first applied. This is important because the Compressor on your air conditioner consumes more power start up than any other device in home. An ac Compressor may consume 45,000 watts of power while the motor is trying to start - ten times more than it uses running. A 5-2-1 Compressor Saver aka hard start kit significantly reduces the amount of time your ac takes.
By comparison, the large burner on an electric stove only consumes approximately 5,000 watts high. It could add years to the life of your Compressor and other electrical components associated with a/c system. Air conditioners with the 5-2-1 Compressor Saver typically start in 30-50% less time than air without product. The heat that accompanies the in-rush current can damage vital electrical components - air conditioner Compressor, run capacitor and contacts.
Start up is the hardest time in life of any type electrical equipment.
