Watsco, Inc. WSO

WSO Company Overview

Watsco, Inc. is a U.S.-based distributor of heating, ventilation, air conditioning, and refrigeration (HVAC/R) products and related services. The company operates primarily in the HVAC/R distribution industry and serves residential, commercial, and institutional markets through a large network of distribution locations. Watsco’s business model centers on supplying equipment, parts, and technical support to HVAC contractors, technicians, and dealers. The company’s principal revenue drivers include the sale of air conditioning systems, heating equipment, compressors, controls, indoor air quality products, and replacement parts. Watsco has historically generated most of its revenue from replacement and repair demand tied to aging HVAC infrastructure and climate-driven cooling needs.

Founded in 1945, Watsco evolved from a manufacturer of refrigeration components into one of the largest HVAC/R distributors in North America. The company expanded significantly through acquisitions and long-term distribution partnerships with major OEMs. Watsco maintains strategic relationships with manufacturers including Carrier Global Corporation, which remains one of its most important suppliers through joint ventures and distribution agreements. Its scale, contractor relationships, logistics network, and technology-enabled sales platform are considered key competitive advantages within the fragmented HVAC/R distribution market.
