About LONG Building Technologies


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, Nevada, Oregon, Washington, and Alaska. With expertise in all major building systems technologies, we serve commercial, institutional and industrial facilities of all types and sizes. We also work with the major Mountain West mechanical contractors and engineers in the application of HVAC and other building technology solutions. To meet the varied needs of our diverse customer base, we are organized into four operating groups: LONG Mechanical Solutions, LONG Security Solutions, LONG Building Intelligence, and LONG Building Environments.

What employees say

Created with Sketch.

The people I work with, and every day seems to be different and challenging.

I am given a great deal of autonomy and, at the same time, my manager is always willing to jump in and help as needed.

It is a challenge.

It is a great place to work.
