New All Climate Comfort™ Series heat pump delivers reliable heating in sub zero temperatures without requiring central or backup heating systems
Mount Vernon, N.Y. — July 21, 2026 — Ice Air, a leader in all-in-one heat pump solutions for multifamily, hospitality, student housing, and mixed-use developments, today announced the launch of the Vertical Stack XC, the newest addition to its All Climate Comfort™ Series of cold-climate heat pumps.
Designed specifically for projects requiring concealed, in-wall vertical HVAC systems, the Vertical Stack XC delivers reliable heating performance when outdoor temperatures are below 0°F while providing the installation simplicity, design flexibility, and individual unit control that developers and building owners demand.
The introduction of the Vertical Stack XC represents a significant milestone for building electrification in cold-weather markets.
For years, extreme winter temperatures have been one of the final technical barriers preventing widespread adoption of all-electric HVAC systems in cities such as Boston, Philadelphia, Chicago, and other northern markets. As municipalities continue to pursue decarbonization goals and building owners seek alternatives to fossil-fuel-based heating systems, the need for reliable cold-climate heat pump technology has become increasingly critical.
“The conversation has changed,” said Ric Nadel, CEO of Ice Air. “For years, architects and engineers asked whether heat pumps could reliably perform during the coldest days of winter. Today, the question is no longer ‘Will it work?’ It’s ‘How should we optimize it?’ That’s a fundamentally different discussion, and it’s helping accelerate electrification across some of the most challenging climate zones in North America.”
The Vertical Stack XC is particularly well-suited for multifamily and mixed-use projects where mechanical room space is limited, gas infrastructure upgrades are costly or impractical, and developers are seeking long-term solutions that align with evolving building regulations and sustainability goals.
By delivering reliable heating performance at below zero temperatures, the Vertical Stack XC enables more buildings to transition away from fossil fuels, simplifies retrofit opportunities, reduces dependence on central heating systems, and provides greater design flexibility for architects and engineers.
“The real story is bigger than a single HVAC unit,” added Nadel. “When a heat pump can provide reliable heating below 0°F, one of the final barriers to electrification begins to disappear. Developers, owners, architects, and engineers can now future proof buildings.”
Key features of the Vertical Stack XC include:
- Cold-climate heating performance down in sub zero temperatures
- Concealed in-wall vertical configuration that preserves usable floor space
- Flexible air distribution with multiple supply-air configurations
- Direct outside-air ventilation capability
- Individual unit control without the need for a central HVAC system
- Compatibility with Ice Air’s smart thermostats and neXus cloud-based building management platform
- Extreme Cooling Performance with a 13.4 SEER2 rating, and a cooling capacity range of 4,700 – 16,000 BTUH, purpose-built for high-demand environments
The Vertical Stack XC is available for specification immediately. The unit is offered with multiple plenum configurations, louver styles, and finish options to support a wide range of architectural and mechanical requirements.
