The 5-2-1 Compressor Saver® helps to lower air conditioning bills in two ways. The first way is that the 5-2-1 Compressor Saver® helps an air conditioner start up in less time. Your air conditioner uses anywhere from 5 to 10 times more power on start-up than it does while running. By reducing that time by up to 50%, there is far less electrical usage each and every time the air conditioner starts. For customers that are on a peak-demand payment program, these savings could be significant.
The second way that the 5-2-1 Compressor Saver® helps to lower air conditioning bills is through the protection it provides to the run capacitor. The run capacitor is the "heart" of the compressor and it determines how much electricity is consumed while the compressor or air conditioner is running. Without a 5-2-1 Compressor Saver® the run capacitor bears the brunt of the stress and electrical heat during start up.
As a result, over time the run capacitor wears down. When the run capacitor wears down, your air conditioner will still work, but it starts to use more electricity to run, just like the last step in a marathon is harder and requires more effort than the first. When weakened, your run capacitor and system can use 10% to 20% more electricity than before!
