This Month in DC Overview: May 2026

This Month in DC Overview

Alex Ayers gives us an overview of the most important things going on in DC this month. Highlights of this month's government affairs issues are:

EPA Final Rule Finally Arrives

After months of anticipation, the EPA officially released its final rule reconsidering the Technology Transition Rule just before Memorial Day weekend. Published on May 27, the rule starts the 60-day countdown to repeal the installation date prohibition.

That change officially takes effect on July 27, 2026. Until then, the EPA’s existing enforcement discretion guidance remains in place, meaning distributors and contractors should continue following current installation guidance for regulated equipment.

Commercial Refrigeration Concerns Remain

The rule also included major changes for commercial refrigeration timelines. EPA delayed implementation of lower-GWP refrigerants until 2032, allowing continued use of medium-GWP refrigerants like R-448A and R-449A in several applications.

HARDI expressed disappointment with the decision, warning it could increase long-term HFC demand while AIM Act requirements continue reducing refrigerant supply. The mismatch between supply reductions and delayed transitions could create future market pressure across the industry.

New York Remains a Major Battleground

New York continues to be one of HARDI’s top advocacy priorities.

Recently, an appellate court granted HARDI’s injunction request related to restrictions on virgin refrigerants R-404A and R-507A. The ruling temporarily prevents implementation of rules that could have caused major refrigerant shortages for commercial refrigeration systems while the broader Part 494 appeal moves forward.

HARDI also launched its first public opinion polling effort in New York focused on HVAC regulations and affordability. The results showed significant concern among homeowners, with 8 out of 10 respondents saying the state should slow or adjust regulations because of potential cost increases.

State-Level Issues to Watch

Affordability concerns are beginning to influence policy discussions beyond New York.

Several states are reconsidering aggressive building code updates amid fears that increasing regulatory requirements could further drive up housing costs and reduce affordability for consumers.

Additionally, the New York DEC released updated FAQ guidance related to Part 494. HARDI encourages members operating in the state to review the latest compliance information carefully.
