G&D Chillers, an Ingersoll Rand company, launched the SUMMIT AIR™ series, a simpler, more cost-effective, reliable line of USA-built, air-cooled chillers for commercial HVAC applications.
G&D Chillers’ SUMMIT AIR™ series air-cooled chillers
In the months since the EPA AIM Act's refrigerant mandate took effect in January 2026 – capping new commercial HVAC equipment at 700 GWP – the company has seen buying activity accelerate across the commercial sector. This full line of commercial air-cooled chillers, ranging from 20 to 200 tons, is available to ship within weeks from the company’s headquarters in Junction City, OR.
"Our reputation was built in environments where failure isn't an option – and that standard doesn't change because the application is a commercial building,” said Justin Thomas, General Manager, G&D Chillers. “Our new SUMMIT AIR series is engineered with the same continuous-duty mindset we've applied for three decades, backed by a service team that is as accessible as we are experienced.”
The SUMMIT AIR series spans 20 to 200 tons across 11 standard models, GD-20T-2 through GD-200T-6. Units run on R-454B refrigerant – A2L-compliant and below the 700 GWP threshold mandated by the EPA AIM Act. Tandem scroll refrigerant compressors, variable-speed EC condenser fans and native BACnet and Modbus integration deliver the efficiency and BAS connectivity commercial engineers expect. All models are designed to meet ASHRAE 90.1-2025 efficiency requirements.
Applications for this series include commercial office buildings, healthcare and medical office facilities, data centers and industrial process cooling and legacy chiller replacement.
"G&D has spent 30 years mastering continuous-duty cooling in the toughest industrial environments," said Thomas. "The SUMMIT AIR series brings that engineering discipline into commercial HVAC – with the added advantage of Ingersoll Rand's distribution reach and an operating model that keeps building owners connected directly to the people who built their system."
The SUMMIT AIR series is available now through G&D Chillers direct sales.
