Our History

Hamilton Smith was founded in 1971 by Doug Hamilton, and Ian Smith. In the beginning the main thrust of the company was refrigeration. Mr. Hamilton left the company in the mid- 1970s, after which time Ian Smith continued to operate the company until 1990, when Paul Martin became the General Manager. Two years later, Paul Martin purchased the company and served as President. In this time, he brought the company to new heights.

In October of 2016, Hamilton Smith Ltd. experienced an exciting transition in ownership. Three long time employees: Bob Connell, Pat Raney, and Andre Palmateer entered into a partnership in the ownership of Hamilton Smith Ltd, purchasing the company from Paul Martin. These three gentlemen have worked and contributed to the successful growth of the company for many years.

Collectively, the three partners have been serving client needs for 44 years and will continue to deliver the highest quality of service our clients have come to expect, and they look forward to continued growth.

Hamilton Smith Ltd. has maintained successful long-term relationships with a diversified clientele through commitment to: quality design, experienced workmanship, equipment and facility maintenance, and quick response time.
