Air Treatment Corporation

What Air Treatment Corporation does

Air Treatment Corporation (ATC) is a 100% employee-owned manufacturer's representative firm headquartered in Brea, California, that distributes and services commercial and industrial HVAC and refrigeration (HVAC & R) equipment across seven western U.S. states. Founded in 1982 and led by President Craig Domagala since 2013, the firm represents over 60 manufacturers—including Baltimore Aircoil Company (exclusive representative for CA, HI, NV), YORK, Johnson Controls, Samsung HVAC, ABB, Hitachi, Lennox VRF, CARNOT, and Colmac Coil—offering air handling units, chillers, VRF systems, cooling towers, refrigeration systems, building automation, and data center cooling solutions. ATC operates six divisions (HVAC, Parts, Service, Cooling Tower, Refrigeration, and Global Mission Critical Service) supported by 11 office locations and two stocking warehouses, with factory-certified sales engineers providing design assistance, startup, commissioning, and warranty service.

The company's revenue is generated through four primary streams: manufacturer's representative commissions on equipment sales to contractors and end-users, OEM parts sales via an online store and direct warehouse fulfillment, factory-certified service and commissioning, and cooling tower maintenance and repair (including proprietary FreedomTuff polyurea coating). Pricing is custom-quote based for equipment and project-based for services, while parts are sold at unit pricing through shop.airtreatment.com. Distribution is field-sales-led with enterprise project cycles, and ATC targets 17 identified verticals—primary among them healthcare and cold storage/food processing—alongside defense, data centers, life sciences, airports, higher education, hospitality, aerospace, manufacturing, and cannabis.

ATC differentiates through territorial density (exclusive manufacturer agreements, regional warehouses enabling same-day parts shipping), factory-certified technical expertise, ESOP-driven employee retention, and 40-plus years of relationship capital with engineering specifiers and mechanical contractors. The firm has no disclosed AI, software, or proprietary technology assets; its competitive position rests on distribution, technical service, and manufacturer portfolio breadth rather than technology differentiation. The Global Mission Critical Service division and recent additions of immersion-cooling and natural-refrigerant partners indicate deliberate expansion into higher-growth, regulation-driven verticals (data centers, ESG-aligned industrial refrigeration).

Expansion highlights4 records

Broad incumbents

• Winsupply: Winsupply is a leading US supplier of residential and commercial HVAC, plumbing, and electrical products and services, operating through a co-op and branch model. Comparable to ATC in product lines represented and contractor channel, though at much greater scale and broader product breadth.
• Watsco: Watsco (NYSE: WSO) is the largest US distributor of HVAC, refrigeration, and plumbing equipment. While ATC is a manufacturer's representative and Watsco is a full-line distributor, both occupy the same value chain layer of representing and selling major HVAC principals to contractors and commercial end-users, making Watsco a comparable for go-to-market model and competitive dynamics.
• Trane Technologies (Commercial HVAC sales channel): Trane Technologies is a global manufacturer and direct seller of commercial HVAC systems. Comparable to ATC as one of the principal OEMs ATC represents, and a direct competitor for the same commercial/industrial equipment sales and service revenue ATC captures through its rep model.
• Ferguson Enterprises: Ferguson (NYSE: FERG) is the largest US distributor of plumbing, HVAC, and water-management products, with a substantial HVAC/refrigeration business. Comparable to ATC's combined plumbing and HVAC product mix, contractor and commercial customer base, and branch-driven distribution model.
• Carrier (commercial HVAC distribution): Carrier is a global HVAC manufacturer with growing direct commercial sales and service capabilities. Comparable to ATC as a competing channel for commercial equipment sales and as one of the principal categories ATC represents via partners like YORK and others.

Direct peers

• Johnstone Supply: Johnstone Supply is a leading wholesale distributor of HVAC, refrigeration, and plumbing supplies serving independent contractors. Comparable to ATC in the contractor-channel distribution model, multi-location footprint, and exclusive territorial member structure, though at significantly larger scale.
• R.E. Michel Company: R.E. Michel is a wholesale distributor of HVAC, refrigeration, and hydronics products with branch locations across the US. Directly comparable to ATC in product categories represented, contractor customer base, and multi-region branch model.
• United Refrigeration: United Refrigeration is a large wholesale distributor of refrigeration, HVAC, and related parts serving contractors and installers across the US. Highly comparable to ATC's refrigeration and parts business in product mix, customer base, and service model.

Emerging players

• CED (Consolidated Electrical Distributors) HVAC division: CED is a major US electrical and broader MEP product distributor that has expanded into adjacent HVAC and building-automation categories. Comparable to ATC in the MEP contractor channel and growing focus on building automation and controls (overlapping with ATC's Reliable Controls and ABB VFD partnerships).
• CaptiveAire Systems: CaptiveAire is a leading US manufacturer and direct seller of commercial kitchen ventilation and HVAC systems. Comparable to ATC's commercial kitchen / food-service HVAC focus, mission-critical service capabilities, and growing direct-to-owner sales model that represents a long-term threat to rep-channel economics.
