This credit also encourages selection of equipment that will last a long time and minimizes refrigerant leakage. Refrigerant charge efficiency, annual leakage rate, and end-of-life refrigerant loss all contribute to your total refrigerant impact per ton.

This credit also encourages selection of equipment that will last a long time and minimizes refrigerant leakage. Refrigerant charge efficiency, annual leakage rate, and end-of-life refrigerant loss all contribute to your total refrigerant impact per ton. Therefore, equipment selection, as well as refrigerant selection, has a substantial influence on the environmental impact of your HVAC system.
