An HTS/DXS/CTI Expert Education Series: Foot Off The Gas

Get ready for BuildingEnergy Boston with this pre-conference webinar sponsored by HTS/DXS/CTI.

January 2024 marked the beginning of the HVAC industry’s rapid, widespread and complex refrigerant transition. Many States now have bans on the use of R-410a and R-134a (and others) in air-cooled chillers, already impacting what can and can’t ship in different States. The first round of national level bans on similar refrigerants by the EPA is also now less than a year away (1/1/2025), heavily impacting any project with construction completion dates of 2025 and beyond. The details and specifics of these rules along with their conflict with our building codes are causing confusion and challenges in the industry. Furthermore, yet another set of national level bans are set to begin one year later (1/1/2026), with even greater conflict with our building codes.

HTS, DXS, and some of our key manufacturers have been heavily involved in this major industry transition for many years, including involvement in ASHRAE standards and technical committees, as well as discussions with industry groups and associations (AHRI, EPA, ETL, ICC, IAPMO, Building Code Agencies, State and Federal representatives and more). Despite efforts by each of these groups, this refrigerant transition still presents the market with uncertainty and conflict, impacting many projects mechanically, structurally, electrically, and architecturally.

The goal of this presentation is to connect the dots and answer as many questions as possible by sharing everything we know and learned thus far. We invite participants from all corners of the industry, from engineers to contractors, building owners, facility managers, energy professionals, and architects. We intend to share our recommendations on how to address current and future designs to alleviate risks associated with these rules. We will also layout the refrigerant strategies from different manufacturers from around the world, and the resulting options for multiple applications.

JS Rancourt
Principal, DXS

JS Rancourt is a Principal at DXS New England (manufacturer representatives for Daikin) focused exclusively in VRV/VRF and ASHP technology. JS is a mechanical engineering graduate from the University of Waterloo in Ontario, Canada, and in 2012 co-founded DXS Ontario, based in Toronto, Canada. JS has been applying ASHPs and VRV/VRF technology in cold climates for 12 years and spearheaded the largest VRV project in North America at the time with over 1,400 VRV units. JS moved to New England in 2016 and founded the local branch of DXS out of Peabody, MA. JS primarily works with consulting engineers and building owners, and prides himself on educating the industry on topics such as ASHPs, VRF, refrigerants and strategic electrification of HVAC.


Mark LaFrance
Principal, HTS New England

Mark LaFrance joined the HTS team in 2012 as a sales engineer, and spent six years in this role working with contractors, engineers, and building owners to gain industry experience and expertise. Mark is a natural-born engineer, who enjoys hands-on work and practical problem solving. His passion led him to pursue a BS in mechanical engineering from the University of New Hampshire, and later earn an MS in mechanical engineering while working as a design engineer and test engineer in the renewable energy industry. Mark has been an active ASHRAE member since 2012, and strives to continue to expand his involvement in the HVAC industry. He brings strong attention to detail, upbeat energy, new ideas, and big picture goals to his role as HTS New England principal.
