Heating, Air-conditioning & Refrigeration Distributors International (HARDI) announced the hiring of Zac Johnson as Senior Policy Lead for HVACR Codes and Rebates. The appointment is intended to strengthen the association’s state advocacy efforts related to building codes, energy policy, and incentive program design affecting HVACR systems.
Johnson most recently served as an R&D Mechanical Engineer at ZIEHL-ABEGG Inc. North America. In that role, he led the design of complex HVAC testing systems and supported global product innovation. Earlier, he worked as a Codes and Standards Engineer at AMCA International, where he represented manufacturers on committees including ASHRAE, NFPA, and IAPMO and contributed to code proposals and regulatory engagement strategies across North America.
At HARDI, Johnson will act as the association’s lead advisor on state and local HVACR code adoption and utility rebate programs that influence equipment installation, compliance, and affordability. His responsibilities include analyzing building, mechanical, energy, and fire code proposals, assessing potential cost impacts, and advocating for rebate and incentive programs aligned with distributor and contractor workflows.
HARDI states it 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 focused on affordability and practical implementation.
“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.”
