New Epa Refrigerant Regulations 2025 New Regulations. The epa’s technology transitions program was updated with a final ruling in late 2023 which prohibits the installation of new residential and light commercial air conditioning. Come 2025, the environmental protection agency (epa) will set a 750 global warming potential (gwp) limit for air conditioning.

The new rules favor hydrofluoroolefins. The refrigeration industry is facing a major shift as new epa regulations demand a move from reactive leak management to proactive prevention.
