Heating, Air-conditioning & Refrigeration Distributors International (HARDI) today announced the hiring of Zac Johnson as senior policy lead on HVACR codes and rebates, aiming to strengthen the association’s growing state advocacy efforts regarding building codes, energy policy and incentive program design.

Johnson brings a blend of hands-on HVAC product engineering and direct codes and standards experience. Most recently, he served as an R&D Mechanical Engineer at ZIEHL-ABEGG Inc. North America, where he led complex HVAC testing system design and supported global product innovation. He previously worked as a Codes and Standards Engineer at AMCA International, representing manufacturers on major industry committees including ASHRAE, NFPA and IAPMO, and helping shape code proposals and regulatory engagement strategies across North America.

In his new role at HARDI, Johnson will serve as the association’s lead advisor on state and local HVACR code adoption and utility rebate programs that affect equipment installation, compliance, and affordability. He will analyze building, mechanical, energy, and fire code proposals; assess cost impacts of potential changes; and advocate for practical rebate and incentive programs aligned with real-world distributor and contractor workflows.

“Zac understands HVACR from the inside out, from the engineering going into proper system installation to national code committees,” said Alex Ayers, Vice President of Government Affairs at HARDI. “His ability to translate complex technical standards into practical policy guidance will strengthen our state and local level advocacy and ensure that codes and rebate programs reflect how equipment is actually designed, distributed, and installed.”

"HARDI supports codes and standards that prioritize safe and efficient installation while preserving consumer choice by allowing multiple compliant HVACR technologies and installation pathways. The association also advocates for rebate and incentive programs that focus on affordability and practicality, ensuring consumers can access efficient HVACR solutions without undue cost or administrative burden."

Johnson’s position serves as a subject-matter expert, providing hands-on technical analysis, policy translation, and external engagement to strengthen HARDI’s voice in regulatory and incentive program discussions nationwide.
