Starting with the development of the first zoning dampers and registers in the 1950s to today, with exclusive Plug & Play dampers  Zonefirst has led the way in excellence and continued innovation.
ZONEFIRST is the first company that successfully developed and marketed HVAC Zoning Systems back in the 1950s and is today a leading manufacturer of HVAC zone dampers and zoning systems. Several other major zoning companies are in business due to ZONEFIRST.
It was in the mid to late 1950s when Richard Foster developed the first automatic motorized dampers, registers and difusers that were thermostatically controlled. He marketed these products under the trade name Zone-A-Trol with another company when in 1964 he founded Trolex Corporation and the start of the well known trade name Trol-A-Temp. In 1999 the Trol-A-Temp brand was acquired by Honeywell.
Since that time, Trolex has continued to manufacture zone dampers for a number of OEMs. In 2004 Trolex re-entered the HVAC market as ZONE-A-TROL and later the ZONEFIRST tradename. This new name signifies the many firsts the company has developed in the HVAC industry. We were the first company to develop automatic dampers, registers, and diffusers for zoning, centralized zone controllers, the first zoning system to feature normally open dampers and the first to zone heat pumps in the early 1970s
