Allied Air is set to launch an extensive range of equipment that uses the refrigerant R-454B, which has a GWP of 466, about 78% lower than that of R-410A.
In recent years, the cost of HVAC equipment has increased significantly, and regulatory changes, such as the phase-down of R-410A, will make the new A2L units even more expensive.
Manufacturers are starting to introduce their A2L systems in the U.S., so contractors and technicians must learn how to service and install this new equipment.
While the refrigerant transition is expected to be relatively smooth due to the alternatives’ similarities to R-410A, dealers should still be aware of its impact on serviceability, product mix, and the HVAC industry overall.
The EPA has finalized SNAP Rule 26, which lists 10 alternative refrigerants as acceptable with use conditions for commercial and industrial refrigeration equipment.
AAON will not increase prices for products that use R-454B, and the company is currently delivering products with R-454B. All newly manufactured AAON products will be configured to use R-454B by the beginning of June.
The new residential line of Lennox heat pumps and a/c units will use R-454B refrigerant. The full line of commercial rooftop units and ducted split systems, including the Model L and Enlight families, will also use R-454B.
