Our History

During the last quarter century, Invensys Controls has evolved from a small start-up company to a dynamic, multi-faceted organization. Today, we offer trade professionals a wide range of HVAC/R products, appliance parts, smoke and carbon monoxide alarms and timing controls. Take a look at how Invensys Controls has progressed over time.

Invensys Controls was founded in 1974 after successfully designing and manufacturing a line of top quality smoke alarms for the residential smoke alarm market. Invensys Controls has continued to focus its efforts toward serving contractors and trade professionals through the electrical wholesale market, a market that it is proud to lead today.
