Overview
Watsco, Inc. is a publicly traded distributor serving the heating, ventilation, air-conditioning, and refrigeration industry. Its business centers on moving equipment, replacement components, supplies, and related products from manufacturers to contractors, retailers, and other professional customers. The company is headquartered in Coral Gables, Florida, and trades on the New York Stock Exchange under the symbol WSO. The business has roots in manufacturing. Its predecessor, Wagner Tool & Supply Corp., was established in New York in 1947, while Watsco, Inc. was incorporated in Florida in 1956. The company initially made parts, components, and tools used in the HVAC and refrigeration sector and became a public company in 1963. A major strategic change began in 1989, when Watsco acquired an 80 percent interest in Gemaire Distributors, a South Florida distributor of Rheem products. That transaction marked the company’s transition from manufacturing toward distribution. During the following decade Watsco built a regional distribution platform through acquisitions and ownership investments. It acquired a 50.5 percent interest in Heating & Cooling Supply in California in 1990 and an 80 percent interest in Comfort Supply in Texas in 1993. In 1996 it purchased the remaining minority interests in Gemaire, Heating & Cooling Supply, and Comfort Supply. The company expanded into additional equipment categories in 1997 by acquiring locations from Carrier and International Comfort Products and entering the refrigeration market. Watsco sold its manufacturing operation in 1998, completing the broad shift toward distribution. The company continued to expand through regional distributors and manufacturer relationships. Its 2005 acquisition of East Coast Metal Distributors strengthened its distribution of Goodman products. In 2009 Watsco formed its first joint venture with Carrier Corporation, deepening its connection with a major HVAC manufacturer. The company subsequently expanded outside the United States, entering Mexico in 2011 and Canada in 2012. It also broadened its geographic coverage in the northeastern United States and moved into the Midwest through the 2021 acquisition of Temperature Equipment Corporation. Watsco’s operating model is based on local and regional distribution capabilities rather than on a single consumer-facing product line. Its offerings include air-conditioning systems, heating equipment, refrigeration equipment, replacement parts, tools, and installation supplies. This makes the company an infrastructure and channel partner for HVAC/R contractors and other trade customers. The company’s geographic footprint, manufacturer relationships, and acquisition program have been central to its development. Reference material reports that Watsco’s revenue passed $1 billion in 1998, $2 billion in 2009, $3 billion in 2012, $4 billion in 2015, $5 billion in 2020, $6 billion in 2021, and $7 billion in 2022; these figures are historical milestones rather than current financial guidance. In 2022 the company was included on the Fortune 500 list. In 2025, reference material identifies the acquisition of Southern Ice Equipment Distributors as a further expansion of its distribution network. Watsco remains an active, publicly listed HVAC/R distribution company operating across the United States and selected international markets.
History
Watsco’s corporate history combines an early manufacturing business with a later strategy built around HVAC/R distribution. The company’s predecessor, Wagner Tool & Supply Corp., was founded in New York in 1947. Watsco, Inc. was incorporated in Florida in 1956 and became publicly traded in 1963. In its first phase, the business manufactured parts, components, and tools used in heating, ventilation, air-conditioning, and refrigeration applications. A leadership and strategic transition took place in 1972, when Albert H. Nahmad became chairman, president, and chief executive officer. The most important business change followed in 1989, when Watsco acquired an 80 percent interest in Gemaire Distributors, a South Florida distributor of Rheem products. Rather than remaining primarily a manufacturer, Watsco began building a distribution network serving professional HVAC customers and representing major equipment brands. Watsco extended this model geographically during the early 1990s. In 1990 it acquired a 50.5 percent interest in Heating & Cooling Supply in California, and in 1993 it acquired an 80 percent interest in Comfort Supply in Texas. In 1996 the company bought the minority interests in Gemaire, Heating & Cooling Supply, and Comfort Supply. These transactions consolidated ownership of several regional distribution businesses and broadened Watsco’s reach across major U.S. markets. In 1997 Watsco acquired locations from Carrier and International Comfort Products and entered refrigeration distribution. The following year it sold its manufacturing operation, completing the strategic move toward an equipment, parts, and supplies distribution company. Reference material states that revenue reached $1 billion in 1998, although the available material does not provide a detailed financial statement or a breakdown by business line. The acquisition-led expansion continued in 2005 with the purchase of East Coast Metal Distributors, a distributor of Goodman products. In 2009 Watsco formed its first joint venture with Carrier Corporation. This relationship reinforced the importance of manufacturer partnerships to Watsco’s model and coincided with the company reaching the reported $2 billion revenue milestone. Watsco then expanded its geographic footprint outside the United States. It entered Mexico in 2011 and Canada in 2012, the year reference material says revenue exceeded $3 billion. Revenue milestones are also reported for 2015, when revenue reached $4 billion, and 2020, when it reached $5 billion. In 2019 the company expanded its presence in the northeastern United States. The company’s acquisition strategy continued in the 2020s. In 2021 Watsco acquired Temperature Equipment Corporation to strengthen its presence in the Midwest; the same year, reference material reports revenue of $6 billion. Revenue reportedly reached $7 billion in 2022, when Watsco was named to the Fortune 500 list. In 2025, the supplied reference material identifies the acquisition of Southern Ice Equipment Distributors, indicating continued expansion in equipment distribution. Across these stages, Watsco developed from a parts and tools manufacturer into a large HVAC/R distribution platform. Its business scope includes air-conditioning, heating, refrigeration equipment, replacement parts, and trade supplies. The company’s role is primarily channel-oriented: it connects manufacturers with contractors, retailers, and other professional buyers through regional distribution operations. Watsco is headquartered in Coral Gables, Florida, remains listed on the New York Stock Exchange as WSO, and operates in the United States, Canada, Mexico, and Puerto Rico.
