5-2-1 Compressor Saver®



The compressor on your air conditioner consumes more power on start-up than another device in your home! The 5-2-1 Compressor Saver significantly reduces the time it takes for your air conditioner to start – SAVING YOUR MONEY AND PROTECTING YOUR EQUIPMENT. Your air conditioner uses 5 to 10 times more power on start-up than it does while running. With this burst of power comes a surge of heat that accompanies the electrical current. This heat damages the compressor, the terminals, the windings, and the run capacitor – all vital components of your air conditioner.


For most homeowners, your air conditioning system is your most expensive equipment. The average home and business experience more than 300 potentially damaging surges yearly. Protect your equipment today! Studies show that the average home or business sees 300 potentially damaging surges each and every year. In fact, with more demand on the power grid, customers are seeing lower quality electrical service, which means even more damaging surges.
