Welcome!

ADEQ uses the newest testing technology and customer service measures to increase the effectiveness of our Emissions Testing, reducing the amount of time you spend in line and resulting in cleaner air and better customer service. 

Why Emissions Testing Is Essential

The quality of the air we breathe is more important than ever. All Arizonans deserve the cleanest possible air today, for our future -- especially those with compromised health. We all can make a positive difference by the choices we make and actions we take everyday. Vehicle emissions contribute to increased levels of air pollution like man-made ozone and particulate matter (smoke and dust). And, for the millions of Arizonans who choose to own and operate motor vehicles, each plays an important role in maintaining and improving Arizona's air quality by simply testing vehicle emissions to ensure they meet health-based standards.

As critical as the quality of air for our communities, is the health and safety of our community and customers we serve and our employees. To continue to provide exceptional service that protects public health, ADEQ has made key changes that put the health and safety of both customers and staff first as we work together to do our part for each other. ADEQ's changes provide as safe of an emissions testing experience as possible -- one that goes above and beyond CDC guidance for other essential services like grocery stores, gas stations, and drive throughs | Learn More >
