Hard Start Kit, 1/2 to 5 hp, 115/288 VAC

The Ranco® Rocket™ RS Series Hard Start Kits are designed to give your air conditioning and refrigeration units a boost! The Ranco Rocket Hard Start Kits help protect and extend the life of expensive compressors and components saving money and energy. When an air conditioning or refrigeration unit turns on, the compressor powers up to begin the cooling process. Starting a compressor requires 4-8 times more electric current, than running it. Over time, this jolt of power places wear and tear on the compressor and other important components. A hard start kit gives the compressor added power during system start-up and reduces the amount of electricity required. Adding a Ranco Rocket Hard Start to an air conditioning and refrigeration system increases energy efficiency up to 98%.
