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.

Spurred on by brutal 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 the Trane people have been building on ever since.

In 2007 Trane was selected to join the Clinton Climate Initiative, a team of business and government partners assembled by former U.S. President Bill Clinton to reduce greenhouse gas emissions from 40 of the world’s largest cities.
