Please be aware that testing procedures have been modified to speed the testing process and minimize close personal contact. Safety is our top priority and we are doing all we can to ensure a safe environment for all. Our emissions inspectors are committed to keeping everyone as safe as possible and do so by wearing masks and gloves at all times, using plastic steering wheel and shifter covers when necessary, and cleaning and disinfecting surfaces regularly.

Only ONE person per vehicle please, and MASKS are REQUIRED. The Statewide mask mandate followed at all Air Care Colorado locations. If you do not have a mask, please get one before visiting an Air Care station. NO MASK, NO TEST.

If you have a medical condition that does not allow you to wear a mask, please call, 303-456-7025, or email, We will work with you to accommodate your needs while protecting our staff.


  • Air Care Colorado, like all Colorado residents and businesses, is navigating the coronavirus (COVID-19) crisis by trusting and following the advice and structures our public health and government officials are putting into place. As always, the health and safety of our staff and customers is our top priority.
