What TMI Climate Solutions does

TMI Climate Solutions is a private Canadian-American custom HVAC manufacturer founded in the mid-1980s, headquartered operationally in Pointe-Claire, Quebec with US manufacturing in Mesquite, Texas. The company engineers and builds custom air handling units (AHUs) and related modular HVAC systems with air volume capacities ranging from 1,000 to 500,000+ CFM and static pressure tolerance up to 12 inches. Core technology includes proprietary Fan Array systems using direct-drive fans with EC motors (ECblue technology), Variable Frequency Module (VFM) controls for energy-efficient speed modulation, EZYFit knockdown panel construction enabling field assembly through standard doorways, and the MiCORE (AHU Designer) in-house selection software. The company is an autonomous subsidiary within Marmon Holdings, Inc., a Berkshire Hathaway-owned industrial conglomerate with $10B+ revenue across 100+ businesses.

The company's business model is project-based, quote-driven, and engineering-led. Its in-house engineering team works directly with end customers, architects, contractors, and a partner representative network (e.g., Thermal Resource Sales) on specification through project completion. Standard production lead times of 30-40+ weeks indicate substantial customized manufacturing cycles and revenue recognition is tied to project delivery rather than recurring licensing. The customer base is concentrated in mission-critical infrastructure verticals: healthcare (e.g., Moses H. Cone Memorial Hospital retrofit), higher education (e.g., DePaul University Theater School), data centers, pharmaceutical and laboratory facilities, industrial manufacturing, government, and retrofit/replacement work in existing buildings.

TMI pursues a sales-led, channel-augmented go-to-market: direct engineering engagement for complex specifications, complemented by a partner network that cultivates basis-of-design prospects early in the project lifecycle. Marketing emphasizes case studies, technical content, and factory visits for partners and customers. The company supports the product lifecycle with services including construction management, preventive maintenance programs, onsite analysis (vibration, infrared, refrigerant), and start-up and warranty support.
