USA-Built Air-Cooled Chillers Feature Low GWP, Open Parts and Backed by Ingersoll Rand
G&D Chillers, an Ingersoll Rand company, is pleased to announce the launch of a simpler, more cost effective, reliable line of USA-built, air-cooled chillers for commercial HVAC applications.
In the months since the EPA AIM Act’s refrigerant mandate took effect in January 2026 — capping new commercial HVAC equipment at 700 GWP — G&D Chillers has seen buying activity accelerate across the commercial sector.
This new, full line of commercial air-cooled chillers, ranging from 20 to 200 tons, is available to ship within weeks from G&D’s headquarters in Junction City, Ore. versus a multiple month delay, which is common with major incumbent OEMs.
“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 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.
