FTOCSRU2, Five Two One,

The 5-2-1 Compressor Saver® protects components by significantly reducing the amount of time it takes for your compressor to start - in some cases up to 50%. This means your air conditioner and compressor will bear - the stress, strain and heat each and every time it starts. Considering that your air conditioner may start up more than 6,000 times in a single cooling season, the positive impact that the 5-2-1 Compressor Saver® has on your air conditioner is significant.
