Manufacturers will no longer be allowed to produce or import HVAC systems using R-410A. Instead, they must transition to refrigerants with a GWP of 700 or lower, such as R-454B and R-32. These alternatives are more environmentally friendly and align with the EPA’s goal to reduce greenhouse gas emissions.

While manufacturing and importing systems with high-GWP refrigerants will be prohibited starting in 2025, installation of systems using these refrigerants is allowed until January 1, 2026, provided all components were manufactured or imported before January 1, 2025.

HVAC technicians will need to update their EPA Section 608 Technician Certification to handle new refrigerants safely. This includes understanding the unique properties of low-GWP refrigerants, such as higher pressures and flammability, which require specialized equipment and safety measures.

The transition to new refrigerants may lead to higher prices for HVAC systems and installation services. This is due to the costs associated with redesigning equipment, training technicians, and ensuring compliance with new regulations.

Systems manufactured before 2025 that use R-410A will still be available for purchase until they are sold out. These units may be more affordable, but it's important to consider the long-term availability of parts and service.

The new regulations are part of a broader effort to mitigate climate change by reducing the use of refrigerants that contribute significantly to global warming. By transitioning to low-GWP refrigerants, the HVAC industry can significantly lower its environmental footprint.
