The Air Conditioning Contractors of America — the largest professional association serving HVAC contractors in the United States — is entering the second half of 2026 under new interim leadership following the June 23 departure of CEO Barton James and the appointment of Martin Hoover, a 41-year HVAC industry veteran from Georgia, as interim CEO while the board conducts a national search. The transition arrives at one of the most active periods for HVAC-related regulatory and legislative activity in the association's history.
James, who served as ACCA's chief executive for several years, became one of the industry's more visible and quotable voices on market conditions and policy challenges, including his assessment of 2025 as a year that was extremely difficult for the HVAC residential market and his advocacy on the regulatory issues that defined much of the industry's 2025-2026 policy agenda. The board's statement framing the transition as an opportunity to position ACCA for its next stage of service, growth, and industry impact signals a forward-looking organizational emphasis on membership growth and deeper engagement with industry partners — two areas where trade association executives who come from practitioner backgrounds often bring credible peer-to-peer relationships that outside executives cannot replicate as quickly.
Active Policy Agenda Under New Leadership
Hoover inherits an active policy docket. ACCA is a co-plaintiff in the federal court challenge to the EPA's Technology Transitions Reconsideration Rule filed June 25 alongside HARDI and PHCC. The challenge targets the rule's commercial refrigeration deadline extensions, which ACCA argues will sustain demand for high-GWP refrigerants at the same time the AIM Act's phasedown is reducing supply — a combination that ACCA projects will drive refrigerant price increases that ultimately burden commercial building owners and the contractors who service their equipment. Hoover has been the named ACCA spokesperson on this issue through his role as interim CEO.
ACCA is also monitoring two additional active regulatory developments: the D.C. Circuit's reconsideration of the 95% AFUE furnace efficiency mandate following the Supreme Court's June 8 remand, and the DOE's newly proposed Process Rule NOPR that would update how future appliance efficiency standards are developed. ACCA's interim CEO has noted publicly that the DOE's Process Rule proposal sets the stage for a balanced rulemaking process if the D.C. Circuit allows DOE to revisit the furnace rule — an interdependent regulatory sequence where the outcome of one proceeding affects the context of another.
Membership and Engagement Priorities
The ACCA board's stated priorities for the association's next phase include expanded national membership, stronger performance measurement, and deeper engagement with industry partners and allied organizations. ACCA currently serves residential and commercial HVAC contractors primarily, with its membership concentrated in companies that complete installation, service, and maintenance work directly for homeowners and building operators. The association's Manual J load calculation standards, Manual D duct design standards, and Quality Installation certification program define the technical standards that ACCA-member contractors are trained to follow.
For HVAC contractors who are not currently ACCA members, the leadership transition and the board's explicit emphasis on expanded membership and deeper industry engagement may signal increased outreach and potentially revised value propositions for contractor-level members who have found the association's programming historically weighted toward its larger residential platform members. Hoover's practitioner background as a working contractor — rather than a career association executive — could facilitate a different kind of member conversation about what the association's advocacy, training, and technical standards programs mean for the day-to-day operations of a residential or commercial contractor in 2026 and beyond.
One test of the new leadership direction will be how ACCA navigates the tension between its residential contractor membership base and the growing commercial HVAC platform environment. Private equity-backed residential HVAC platforms — including Apex Service Partners and Champions Group — are ACCA member companies through their subsidiary brands, but they represent a different constituency than the independent residential contractor who is the association's historical core. How the association balances the interests of large PE-backed operators, independent residential contractors, and commercial mechanical contractors will be one of the defining strategic questions for ACCA's next permanent CEO.
In the near term, Hoover's stated priority of maintaining steady operations and supporting staff while the search proceeds is exactly the right posture for an interim appointment. ACCA has a well-established policy presence, a credentialed technical standards organization, and an active regulatory docket — none of which requires a permanent CEO to continue effectively. The board's search for a genuinely strong permanent leader is more likely to succeed by taking the time to identify the right candidate than by rushing to fill the role. For ACCA's contractor members, the most important outcome is that the association's advocacy and technical programs continue to function effectively while the transition unfolds.
