Founded in 1994, the original Tekgard® brand has a history of collaborating with clients to develop innovative solutions to unique and challenging requirements in several industries. Since 2003, the company has designed and manufactured the most reliable, user-friendly ruggedized HVAC equipment available on the market. Soon afterward, Tekgard® quickly became the first company to supply an Environmental Control Unit that fully met the customers’ capacity, power consumption, and weight requirements while operating in the harsh conditions dictated by the military’s demands.

Tekgard® joined the ACT family in early 2021. With a shared focus on innovative solutions and exceptional customer experiences, both teams look forward to leveraging each other’s thermal and mechanical experience to provide an unparalleled range of thermal solutions.

The York location joins the ACT company with the same Core Values of Innovation, Teamwork and Customer Care with a history of commitment to collaborative solutions and industry-leading quality systems.
