His first contact with the industry was with the Mexican company Interfil, in his time as a university student in the early 80s; at that time he worked in the areas of purchasing, production and sales. Over the years he joined Dupont where he performed technical and commercial work in the area of chemical fluoro.
Years later he was a consultant for several environmental agencies of the United Nations (UN) to provide his services in the commitment of the region for the elimination of all products with chlorine content. All this background is what Antonio Estévez considers fundamental for his time at Copeland (Emerson Electric) as sales manager for a period of more than six years. He arrived at Trane in 2003 when he was invited for a project that according to him "has been aggressive, demanding and that has required innovation, creativity and perseverance for the opening of a supply chain of original components and all the accessories for the installation and maintenance of refrigeration, ventilation and heating equipment" and adds that "it has been the best challenge in my professional life due to the size and scope of the project, as well as the impact on our industry."
