The focus this month is a brief look at the American Innovation and Manufacturing act or AIM act for short. This policy seeks to dramatically reduce the usage of HFC refrigerants with the target of a 85 percent reduction by 2036. The goal of the policy is to reduce the amount of refrigerant with high
