LONG Building Technologies was founded in 1965 as a manufacturer representative of HVAC equipment. The name of the company evolved from Long-Deming to Long & Associates and finally LONG Building Technologies.

Over the years the company has diversified and grown from a small manufacturer representative in Colorado to a regional company with offices in Colorado, Wyoming, Utah and Nevada.
