Watsco
The buyer who changes nothing

Dean Blackley started running an HVAC branch in Buffalo, New York, in 1971. Thirty years later he still could not get a common compressor onto his own shelf.

The branch that ran out of compressors

Blackley's branch had been swallowed by Pameco, a national distributor that went public in May 1997 and then bought companies at speed, adding a president of acquisitions in 1997 and a $240 million credit line in 1998.

The buying worked. However, the owning did not go so well.

The head office in Colorado told branch managers how to run their branches. Product lines changed every three years, so customers stopped knowing what they were buying. Purchasing sat far away from the man who knew which compressor Buffalo sold every week. "Every new boss had a new grand scheme," Blackley told Supply House Times in 2004.

​Pameco filed for Chapter 11 in June 2003. Two months earlier, Watsco had quietly bought 43 of its locations across Texas, Louisiana, Arkansas, and Mississippi, carrying $55 million of annual revenue between them.

What Watsco did with the wreckage

Watsco restocked the shelves and gave the branches their identities back. In distribution the relationship lives at the counter, with the person who knows that a contractor on a Tuesday afternoon needs the part today or loses the job.

The head office cannot hold that relationship. It can only fund it or break it. Two of the groups it picked up returned to their original names, Belleville Supply and Thermal Supply, and were left to decide locally what they needed to carry.

The approach was already fourteen years old by then, and it came from the first deal Watsco ever did.

The 1989 purchase that set the rule

In 1988 Watsco was a small Florida parts manufacturer with about $22 million in revenue. The next year it paid roughly $17 million for 80% of Gemaire Distributors, a Fort Lauderdale air conditioning distributor several times its size. Albert Nahmad, who had taken control of Watsco in 1972, kept the Gemaire name on the building

Gemaire still trades under that name today.

​According to Watsco’s Q2 2026 reports, since 1989 Watsco has bought more than 70 businesses and produced an 18% compounded annual total shareholder return. Almost none of the sellers were absorbed. Buying a fragmented industry one family business at a time works when you leave the families in charge.

The two halves of a Watsco deal

Look at what changes hands and what does not.

The seller keeps the name, the leadership, and the local calls on inventory and customers. When Watsco bought Gateway Supply of Columbia, South Carolina, in 2023, the second generation of the founding family, Chris, Sam, and David Williams, stayed in charge. "Watsco was the logical choice to sustain Gateway's legacy and unique culture," Chris Williams said at the time. The pattern repeated in June 2026 with Jackson Supply, a $230 million distributor across 25 Sunbelt locations serving about 5,000 customers.

Watsco supplies the balance sheet, the equity plans that make branch employees owners, and one more thing that a family distributor can never afford alone.

The one thing they centralize

Software.

Based on their Q2 reports, Watsco has put more than $250 million into digital platforms over five years and now spends at an annual rate near $68 million. More than 70,000 contractors and technicians use those tools. E-commerce reached $2.7 billion in the twelve months to 30 June 2026, or 37% of sales, growing 13% in the first half while total revenue grew 1%

The quoting tool matters more than the website. OnCallAir lets a contractor sit in a homeowner's kitchen, build options, add financing, and close. Over the same twelve months contractors used it to quote roughly 342,000 households and moved $1.9 billion of goods, up 15%.

A $230 million family distributor cannot build that. A network of more than 700 locations can build it once and hand it to every branch it owns. The autonomy costs Watsco nothing in scale, because the scale lives in the software layer that sits underneath the local names.

What this looks like on your side of the table

Here’s what you can take away from all this:

Write down what the seller keeps

Before the letter of intent, list the decisions that will actually change hands: pricing, hiring, inventory, branding, and compensation. Mark each one keep or transfer, and put the list in front of the seller. You know it worked when the seller can recite all five without checking their notes a month after closing.

Buy the relationship, then price the legacy

Call five of the target's customers during diligence and ask who they phone when a job goes wrong. If they name a person at the branch, that person is most of what you are buying. If they name the company, you are buying inventory and a lease.

Centralize only what compounds across every unit

Audit your last four integration projects. Anything that helped one location goes back to that location. Anything that gets better as more units use it, like pricing data, e-commerce, or a quoting tool, belongs in the middle. The signal is unmistakable: acquired teams start asking for the shared tool.

Pay part of the price in ownership

Watsco pushes long-term equity into acquired teams as part of the deal. Count the managers you acquired in the last two years who hold equity today. If the number is zero, you bought the branches and rented the people.

What the next seventy deals depend on

Watsco finished June 2026 with $464 million in cash, no debt, and a 52-year run of paying dividends, having raised the annual rate 10% to $13.20 a share in April. More than 2,100 HVAC distributors remain in North America. The limit on the next 70 deals is the number of families who believe the name stays on the building.
