Revised Section 608 Refrigerant Management Regulations
EPA is updating the safe handling requirements under Section 608 that currently apply to ozone depleting refrigerants and extending them to substitutes like hydrofluorocarbons (HFCs). These changes strengthen the existing program, in particular by requiring a number of industry best practices. This action reduces climate-damaging emissions from air conditioning and refrigeration equipment. EPA estimates that the annual emissions reductions from this rule will be approximately 7.3 million metric tons of carbon dioxide equivalent (MMTCO2eq) and 114 ozone-depletion weighted metric tons (ODP tons).

The HVACR industry has less than one year to prepare for what the government has deemed the “largest energy-saving standard in history” as the U.S. Department of Energy’s (DOE’s) energy conservation standards for commercial air conditioners and heat pumps and commercial warm-air furnaces, otherwise known as rooftop units (RTUs), are scheduled to take effect Jan. 1, 2018.
The rooftop air conditioner standards — which will cover new units found on low-rise buildings, like hospitals, schools, and big-box stores — will take effect in two phases, increasing minimum efficiency by about 10 percent as of Jan. 1, 2018, and by 25-30 percent as of Jan. 1, 2023. Standards for new warm-air furnaces that are typically installed in conjunction with commercial air conditioners also become effective in 2023.
