Three of the HVAC industry's largest trade associations — Heating, Air-conditioning & Refrigeration Distributors International, Air Conditioning Contractors of America, and Plumbing-Heating-Cooling Contractors—National Association — filed a federal legal challenge to the Environmental Protection Agency's Technology Transitions Reconsideration Rule on June 25, arguing the rule unlawfully extends compliance deadlines for commercial refrigeration applications in a way that will drive up HFC refrigerant prices and disrupt the industry's planned transition to lower-global-warming-potential refrigerants.
The challenge is directed specifically at the EPA's decision to allow continued manufacture of certain new refrigeration systems using higher-GWP refrigerants in supermarket, retail food, and cold-storage applications — a change from the original 2023 Technology Transitions Rule that had set stricter compliance timelines for those sectors. The trade associations argue that EPA's action effectively increases demand for HFC refrigerants whose production is simultaneously being reduced under the American Innovation and Manufacturing Act's ongoing phasedown schedule, creating a supply-demand imbalance that will manifest as sustained price increases for the refrigerants on which HVAC contractors and building owners depend.
The Supply-Demand Argument
HARDI CEO Talbot Gee said the reconsideration rule's treatment of commercial refrigeration is legally flawed, economically reckless, and directly at odds with the AIM Act. Gee argued that by extending the deadlines for commercial refrigeration applications to transition away from high-GWP refrigerants, the EPA was keeping demand for those refrigerants elevated at the exact moment the AIM Act is reducing supply — a combination that, left in place, will push prices higher across all HVAC applications that use the same refrigerant pool, not just commercial refrigeration.
Alex Ayers, HARDI's vice president of government affairs, cited EPA's own economic analysis projecting refrigerant prices could rise 12% to 24% by 2029 as HFC supplies continue to decline under the AIM Act's phasedown. He characterized that as inflation between 4% and 8% per year over the next three years, a sustained rate he said will have a major long-term impact on the maintenance costs of commercial refrigeration systems installed or serviced today, since those systems typically remain in service for 15 to 30 years. PHCC CEO Cindy Sheridan said the decision creates confusion for contractors who install and service this equipment and ultimately hurts the consumers who pay the maintenance bills.
The R-410A Carve-Out the Trade Groups Support
The trade associations were careful to distinguish between the specific provisions of the reconsideration rule they are challenging and a separate provision they support. The EPA's reconsideration rule also removed the January 1, 2026, installation deadline for residential and light commercial air conditioning and heat pump systems using R-410A, a change that prevents distributors and contractors from being stuck with inventory of R-410A equipment they legally manufactured before the new refrigerant rules took effect but cannot sell. The trade groups said this R-410A provision is a sensible correction and expressed support for it taking effect as scheduled on July 20. The legal challenge is targeted at the commercial refrigeration deadline extensions, not at the R-410A installation deadline removal.
ACCA's interim president and CEO Martin Hoover noted a secondary concern: that the extended commercial refrigeration deadlines will accelerate pressure for a rushed transition to A3 (highly flammable) refrigerants and encourage a patchwork of state-level regulations as states fill the gap left by federal inaction. New York, he noted, had sought to ban some virgin refrigerants immediately, and that state has prohibitions on A2L equipment in specific product categories taking effect in 2027, 2030, and 2034. Allowing federal commercial refrigeration deadlines to slip, ACCA argues, increases the likelihood that other states will take similar independent action, producing the fragmented regulatory environment that national standards are designed to prevent.
What Contractors Should Do Now
ACCA's vice president of government relations Sean Robertson said refrigerant price increases are coming regardless of the legal outcome, since the AIM Act phasedown is reducing supply on a fixed statutory schedule. He urged contractors to prioritize refrigerant recovery as both a business and regulatory matter, describing recovered refrigerant as an increasingly valuable company asset. Robertson also urged contractors to educate customers that current regulations do not require early replacement of working systems, and that the appropriate focus for customers with high-leak-rate equipment is repair and leak mitigation rather than simply topping off systems with expensive and increasingly scarce refrigerant.
