AirSource Technologies was formed in 1990 in response to the emerging market for compliance and investigative emission source testing triggered by the EPA Clean Air Act and its subsequent amendments.

The company is led by Pete Liebl who is certified as a Qualified Stack Testing Individual (QSTI) and has over 30 years of experience. The QSTI certification program is administered by the Source Evaluation Society’s (SES) program and assures individuals have proven their knowledge of source testing methods and fundamental engineering and chemistry principles. This is just one more way to assure our clients they are in good hands with AirSource Technologies.

AirSource Technologies served a relatively small regional client base in its early years. However, having developed a reputation for competence with a number of technically complex methodologies and emission sources, word-of-mouth referrals have further enhanced the company’s reputation on an international basis. That word-of-mouth has sent us all over the globe, including more than 30 states, Switzerland and even South Korea.
