CoolSys delivers end-to-end HVAC-R lifecycle services organized across four verticals: (1) commercial and industrial refrigeration and HVAC installation, preventive maintenance, and emergency repair; (2) professional solutions including MEPR/FP engineering, electrical engineering, equipment sourcing, and multi-site program management; (3) energy solutions encompassing consumption optimization, CHP/cogeneration, Bridge-to-Grid systems, Battery Energy Storage, and microgrid design; and (4) facility solutions covering asset recovery, refrigerant compliance, and pavement management. Notable technical capabilities include 250+ CO2/transcritical refrigeration systems installed (including 4 of the largest transcritical systems in the U.S.), centralized refrigerant compliance for AIM Act, EPA Section 608, California CARB, and Washington WAC 173-443, Energy Management System (EMS) monitoring, and predictive analytics layered on top of third-party monitoring infrastructure.

The business model blends project-based installation revenue (one-time), recurring multi-year preventive maintenance subscriptions (annual billing cadence), 24/7 transactional emergency repair services, professional services for engineering and energy optimization, equipment procurement and resale, used asset recovery, and refrigerant compliance subscriptions. GTM is enterprise field sales targeting national multi-site operators with dedicated account management, complemented by a 24/7 emergency dispatch hotline (866-417-6586) and local branch fulfillment. Growth has been driven by an aggressive programmatic roll-up: 20+ acquisitions since 2018, including T&O Refrigeration, 1GNITE Asset Recovery, ABC Refrigeration & HVAC, and Mechanical Engineering & Construction Corporation (MEC2). The company completed a $150 million credit facility led by Muzuho in September 2025 and installed a new CEO (Eric Hutto) effective May 2026.
