By now, all ASA members in the HVAC sector should be up to date on the transition to low-global Warming Potential (LGWP) refrigerants.
The federal AIM Act requires an 85% phasedown of HFC refrigerants by 2036. Many states have already updated their building codes to allow for the use of LGWP refrigerants, such as A2L, while other states, such as California, have set specific timelines for compliance.
