A hard start kit is designed to assist your compressor on start-up. Your air conditioner works like a pump circulating the refrigerant throughout your system. The harder the pump has to work the less efficient it is and the more likely it is to break down. A hard start kit helps your air conditioner when it needs help most! The addition of a hard start kit will extend the life of your compressor, which could save you from the high cost of a repair or replacement.
Let your air conditioner do "highway miles...instead of city miles"
By stopping your unit from going on and off (short-cycling) so much, a time delay relay keeps it from wearing out prematurely. A time delay relay is also the perfect accessory for families that have children who like to play with the thermostat. No matter how often you change the setting on the heat/cool switch or the fan on/auto switch, you can't burn out your compressor. This is because the time delay relay won't turn your system on for 3-5 minutes after the last thermostat adjustment has been made.
