In extreme heat, refrigerant pressures are higher, making the compressor work harder to start. The hard start kit provides the extra torque needed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch4\u003eMy AC is only 2 years old. Does it still need a hard start kit?\u003c\/h4\u003e\n\u003cp\u003eEven new systems benefit from a hard start kit, especially if you have a long lineset (over 50 feet), are in a hot climate, or have experienced voltage issues. It is inexpensive compressor insurance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch4\u003eCan I install this myself?\u003c\/h4\u003e\n\u003cp\u003eYes, if you are comfortable working around electrical components. Turn off power at the disconnect, connect two wires to the contactor, and restore power. However, if unsure, hire a licensed technician.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch4\u003eDoes this work with heat pumps?\u003c\/h4\u003e\n\u003cp\u003eYes, it works with both AC and heat pump compressors in the 2 to 3.5 ton range.\u003c\/p\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e","brand":"National HVAC Parts","offers":[{"title":"Default Title","offer_id":63004087714163,"sku":"NHVAC-HARD-3N44Z5","price":32.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/71rxFlgTwuL._AC_SL1500.jpg?v=1781918095","url":"https:\/\/nationalhvacparts.com\/products\/5-2-1-compressor-saver-hard-start-kit-csr-u2-2-to-3-5-ton-units","provider":"National HVAC Parts","version":"1.0","type":"link"}
