The Path to Acceptance: History of VRF Zoning Regulations in the U.S.

Variable Refrigerant Flow (VRF) zoning technology is the fastest growing HVAC technology in the industry today. Mitsubishi Electric introduced the technology to the U.S. more than 10 years ago and has spent the last decade building the category nationwide.

VRF zoning now fills an enormous gap in the country’s cooling and heating needs, but in the early 2000s there was little awareness of this technology. We realized then that the success of VRF zoning technology in the U.S. required a paradigm shift in how the industry and end users thought about cooling and heating solutions.

To initiate this shift we focused on two approaches: to build training and market education at the grass-roots level and to simultaneously spearhead government regulations.

We knew that certification was critical to industry acceptance and, by extension, to end users. We became active members of the HVAC and energy communities, chairing ASHRAE committees, participating in DOE discussions, meeting with members of Congress and becoming active in AHRI. We are proud to have pioneered the introduction of this technology to the U.S. and the subsequent regulatory acceptance.

We have achieved many milestones already and today have an entire department dedicated to advocating for the unique performance capabilities of VRF zoning in the U.S. To see how far we’ve come, here are some of the regulatory milestones that have paved the way to official industry recognition of VRF zoning technology:
