Every time your air conditioner starts up on a hot summer day, the compressor draws a big burst of electricity to get moving. ☀️
That initial surge puts real stress on the motor, and it happens over and over again every time the system cycles on and off. A hard start kit is a small device installed near the compressor that gives it an extra boost of power right at startup. This lowers the initial amperage draw, which means less wear on the compressor motor with every cycle.
Over the course of a summer, with your AC starting dozens of times a day, that reduction in stress makes a real difference. Hard start kits are particularly helpful during heat waves when the system runs almost constantly, and the compressor gets very little rest between cycles.
For older systems, or any unit that hesitates or struggles a bit when starting, a hard start kit is a relatively simple addition that can add years to the life of the compressor and help you get more out of your current equipment.
