Are you managing a business, office, retail space, or commercial property in Goochland, VA? If your HVAC system uses R-410A, you may have questions about the refrigerant transition taking place in 2026.
Do you need to replace your system? Can you still schedule a commercial HVAC repair? What does R-454B mean for your next service call?
The short answer is reassuring: you usually do not need to replace a working R-410A system just because of the AIM Act. You can continue to maintain and repair existing equipment. However, new system installations are increasingly moving to lower-GWP A2L refrigerants such as R-454B and R-32.
Here is what you need to know before your next commercial HVAC service appointment.
The American Innovation and Manufacturing Act, or AIM Act, directs the United States to reduce the production and use of high-global-warming-potential HFC refrigerants.
The EPA’s goal is an 85% phasedown of HFC production and consumption by 2036. The transition affects new air-conditioning, heat-pump, refrigeration, and commercial HVAC equipment.
R-410A has been widely used in air conditioners and heat pumps for years. Its global warming potential is approximately 2,088. R-454B has a much lower GWP of approximately 466, while R-32 has a GWP of approximately 675.
That difference is why equipment manufacturers are developing new systems around R-454B, R-32, and other lower-GWP options.
The transition affects new equipment and refrigerant supply more than it affects your currently operating system.
The EPA restrictions apply by equipment category. Dates can vary for light-commercial systems, rooftop units, variable refrigerant flow equipment, chillers, and other commercial applications. State and local requirements may also apply.
For your business, the practical changes include:
You should not allow anyone to simply add R-454B or R-32 to an R-410A system. The refrigerants have different characteristics, and the equipment must be designed for the refrigerant being used.
“Your business does not need to make a rushed decision just because refrigerant regulations are changing. The right approach is to understand your current equipment, repair what makes sense, and plan ahead for the next replacement.”

In many cases, yes.
The EPA’s Technology Transitions Program does not require you to remove every existing high-GWP system from service. You can generally continue to operate, maintain, and repair your existing R-410A equipment throughout its useful life.
A qualified technician may diagnose and repair problems involving:
A commercial HVAC repair may be the most practical choice when your system is in reasonable condition, replacement parts are available, and the repair cost supports continued operation.
You may want to discuss replacement when your system has repeated leaks, major compressor failure, severe corrosion, poor efficiency, or repair costs that are approaching the value of the equipment.
Not automatically.
Your next step should depend on the condition, age, efficiency, refrigerant charge, and repair history of your equipment. A commercial rooftop unit that has been maintained regularly may have several useful years remaining. A system with repeated failures may justify a replacement plan.
Your technician should review:
You should also remember that commercial equipment categories are not identical. The requirements for a small light-commercial split system may differ from those for a large rooftop unit, VRF system, or chiller.
