We’ve heard it said before, “heat pumps don’t work in cold climates…”, but is it true?

While older, single speed heat pumps really weren’t up to snuff in frigid weather, today’s top-of-the-line cold climate heat pumps maintain their output at 5°F and can keep a building warm well into the negatives.

Variable refrigerant flow (VRF) is one of the most efficient options currently available for electrifying commercial HVAC in cold climates—especially when used in the right types of buildings. When installed correctly, VRF can reduce the energy use and carbon emissions of commercial and multifamily HVAC systems in cold regions.

In this Manufacturer’s Roundtable where we’ll discuss the practical applications of, and best practices for, cold climate VRF. This discussion will center around use cases and case studies about how this technology is being deployed in the field, and take a look at emerging products.

Panelists:

James Momperousse, Energy & Utility Sales Manager, Carrier
James plays an active role in maximizing clean energy opportunities for Carrier Ductless and VRF products. He is integral in ensuring Carrier maintains a competitive product, keeping up with regulatory and incentive standards. With his Mechanical Engineering background from Florida International University as well as 10 years of HVAC experience, James brings a passion for electrification and making highly efficient HVAC equipment affordable.

Chris Bradt, Senior Business Development Manager, LG Electronics
Chris works with the Utilities Sales Team at LG Electronics’ Eco Solution group, supporting market engagement across the West to deliver heat pumps for space conditioning and water heating that exceed expectations. He joined LG in 2024, bringing 18 years of experience collaborating with building performance professionals and leading programs, including all-electric building solutions for both retrofits and new construction. Chris likes to make things happen—and he lives in a heat pump equipped home in Oakland, California.

Matthew Connolly, Commercial Applications Engineer, Daikin Comfort
With 17 years of field experience, Matthew is an experienced VRV/Commercial Applications Engineer. He has worked in product development and project design for both commercial and residential projects, including VRV and VRF.

Cain White, Director of Commercial Product Support, Mitsubishi (METUS)
Cain brings nearly three decades of HVAC industry experience to his role. Since joining METUS in 2012, he has held leadership roles across service, technical operations, and product management. He played a key role in launching major technologies such as the QAHV commercial heat‑pump water heater and the world’s only simultaneous HVRF system. He now serves as a vital link connecting customers, sales teams, product management, engineering groups, and global manufacturing partners. Before moving to the U.S., Cain spent 15 years in the UK managing large commercial HVAC and refrigeration projects.
