The basics...


Envirotest Corp., a member of the Colorado Better Business Bureau, operates the Air Care Colorado emissions testing facilities under contract to the State of Colorado.

Envirotest is a subsidiary of Opus Inspection, a multi-national company with more than 1,300 employees dedicated exclusively to motor vehicle inspection.

Opus Inspection conducts operations in 22 states and several countries.  Building on an unmatched record of success and customer satisfaction, Opus Inspection has become the industry leader in providing professionally-managed solutions for centralized and decentralized Inspection and Maintenance (I/M) programs that apply leading edge technology to data management, safety and emissions testing equipment, as well as on-road data collection through program components like Colorado's RapidScreen.

In addition to the Air Care Colorado program, Opus Inspection manages seven centralized vehicle inspection programs in the U.S. and a number of decentralized programs and facilities.  Opus Inspection manages international programs in Bermuda, Mexico, Perú and Sweden.

At Opus Inspection, our roots are deep, representing more than 40 years of industry innovation.  In 1974, we were the first company to provide computerized emissions analyzer testing systems for vehicle inspection programs.  Two years later, we began the first contractor-managed vehicle inspection program in the U.S.  Our System1 Gen3 inspection system, designed in 2013, is our most current generation of computerized inspection equipment and it provides state-of-the-art accuracy and reliable functionality. 

Opus Inspection provides a full complement of program management services for our vehicle inspection clients.  We work in partnership with government agencies to manage any or all aspects of their regulated programs.  These services are applicable to both centralized and decentralized vehicle inspection networks.
