TSI was formed in 1980 by the original owners Phil McMullan, Bill Achenbach, Chris Maher and David Smith, then Jim Williamson joined the company as an owner in the mid 1980s. TSI was one of the first companies in the country to use infrared technology as a major source of revenue as we used thermal cameras to assess energy loss in government and private buildings as part of our thermal imaging energy audit protocol. We were also one of the first companies to use blower doors and duct blasters to identify air leaks in homes, commercial buildings and ductwork systems.
