Watsco shares jumped 221% as furnace parts quietly beat most of Wall Street
Watsco sells heating and air parts to contractors across North America.
The short version
- Shares climbed 221% over ten years in a dull business.
- A broken furnace in January makes homeowners pay whatever it costs.
- Replacement demand keeps cash rolling in when consumer spending drops.
Furnace parts and pipe fittings sound like the least exciting businesses imaginable, yet the companies stocking those shelves have quietly outpaced most of Wall Street over the past decade. According to 24/7 Wall St., Watsco shares have risen 221.06% over the past ten years, and Ferguson Enterprises shares have gained 426.31% over the same period.
Both companies sell strictly to contractors who fix broken air conditioners, furnaces, and pipes. A homeowner sitting in a freezing house with no heat in January makes the call on whether the economy is doing well. Watsco, the largest distributor in the ~$74 billion North American HVAC/R market, makes nothing itself.
It buys heating, cooling, and refrigeration equipment from major manufacturers and sells parts to over 70,000 contractors from about 650 domestic locations. The market is crowded with more than 2,100 distributors, so Watsco grows by buying regional operators and letting them run themselves.
In June 2026, it bought Jackson Supply, which brings in $230 million in annual sales and runs 25 Sunbelt locations. Replacement demand comes from equipment failure, not consumer sentiment. As Watsco’s president noted, the products sold are a sheer necessity and the installed base keeps expanding.
During a 2025 industry downturn where units dropped 17%, Watsco still earned $497 million in net income and generated $570 million in operating cash flow with zero debt. In April 2026, Watsco raised its annual dividend 10% to $13.20 per share, marking its 52nd consecutive year of payments through every major economic crisis.
Your own contractor does not care about Wall Street trends when your blower motor goes on the hottest day of July.
