For more than a century the Trane name has identified products and technology that stretched the world's idea of what was possible – a tradition that's still very much with us.

In many ways Trane is a classic American success story that grew into a global one. It began with our founder, James Trane, a Norwegian immigrant who opened his own plumbing shop in La Crosse, WI, in 1885.

With the inspiration of cold Wisconsin winters, James Trane invented a new low-pressure heating system he proudly called the Trane Vapor Heating System. His son, Reuben, was just back from college with a degree in mechanical engineering, so father and son began manufacturing operations in 1910 and incorporated as The Trane Company in 1913. It was Reuben's invention of the convector radiator in 1923 that firmly established the company's reputation as an innovator, a reputation Trane people have been building on ever since.

Growth through innovation

The idea of using technology to give people relief from summer heat was a radical and unproven idea when Trane became an air conditioning pioneer in 1931.

Trane fundamentally changed the concept of air conditioning large buildings with the 1938 launch of Turbovac, the industry's first hermetic, centrifugal refrigeration machine. This was the beginning of a long chain of innovations leading to Trane's current CenTraVac ®, the industry standard for large commercial air conditioning systems. This is the most energy efficient system available anywhere for large buildings and it has earned Trane the "Best of the Best" Award from the U.S. Environmental Protection Agency.

Expanding our offer to customers

With the acquisition of Sentinel Electronics in the late 1970s, Trane moved into the important building automation and management field. The company was the first to offer integrated controls for all its products and became a leader in the still new field of energy management, a leadership position that continues to expand.

Our days as a leader in residential air conditioning began in 1982. That's when we took advantage of an opportunity to acquire General Electric's Central Air Conditioning Division.

We're proud that over the decades we've enriched the scope of our products and technology as well as the scope of the total solutions we can offer each customer.

In 1984 Trane was acquired by American Standard Companies and remained the largest of its three businesses: Air Conditioning Systems and Services, Vehicle Control Systems (WABCO) and Bath and Kitchen.

On Nov. 28, 2007 we successfully completed a plan announced the previous February to separate the three American Standard businesses, leaving each free to concentrate exclusively on the markets it knows best. . Over the course of the year WABCO was spun off as an independent corporation and Bath and Kitchen was sold to Bain Capital Partners. On Nov. 28th American Standard Companies changed its name to Trane, with its stock trading under the new symbol "TT". Our new name reflects our business focus and our leadership in providing integrated heating, ventilation and air conditioning services and solutions.

New chapters in our history of growth through innovation are being written every working day. Our momentum continues to build because -- as our people have said for years -- "it's hard to stop a Trane."
