Hard start kits are said to be designed for assisting the compressor upon start-up. If the inside air conditioning coil is situated approximately 50 ft from the outside condensing unit, you almost certainly need a hard start kit for assisting the compressor whenever it turns on. If you take a close look, you will notice that the air conditioner works like a pump distributing the refrigerant all through the system. The harder your air conditioning pump works the lesser effectual it is and the more probable it is to fail. Hard start kit helps your air conditioner when it needs maximum help, when it starts up at first and has to initiate the pumping process. Supplementing your air conditioning system with a hard start kit will lengthen the life of the compressor, which in turn will help you avoid extra expenditures save from the high cost of replacement or repair.
