90 years ago, a single location opened. There was no road map for what this company would become. There was no long-term strategic plan outlining decades of growth, no clearly defined expansion model, and no guarantee that the business would extend beyond its earliest years. What existed instead was something far less structured—but ultimately far more powerful.

Today, our mission continues across 55 locations, serving HVACR professionals throughout 16 states.

WE . . .
Contribute to our customer’s success
Carry the best products in our industry
Offer valued business solutions
Provide all stakeholders an opportunity to succeed . . WIN TOGETHER

From a single shop in Madison to a company serving customers across multiple regions, the story of the Gustave A. Larson Company has been built over time. Not through a single moment, but through a pattern of decisions made consistently—year after year. Through relationships that were earned, work that was done with care and a commitment to doing things the right way.

Ninety years is a milestone. But it is not the conclusion. Today, we celebrate ninety years of vision, dedication, and service—a legacy built by generations of people who believed in doing the work with care and purpose. The business continues to evolve and the industry continues to change. New opportunities will emerge. What remains constant is the foundation, and the responsibility to build on it.

As we celebrate our 90th Anniversary, we're grateful for the customers, vendor partners, and team members who have been part of our journey.
Here's to 90 years of trust, service, growth—and the next chapter ahead.
