What is the EPA 608 Certification?
Mandated by the Federal Clean Air Act, the EPA 608 Certification is a legal requirement for any technician who maintains, services, repairs, or disposes of appliances that contain regulated refrigerants. Simply put: You cannot buy refrigerants without it.
A Recession-Proof Career
According to the Bureau of Labor Statistics (BLS), job openings for HVAC installers and mechanics are projected to swell by 8% between 2024 and 2034. This growth is driven by erratic weather patterns and the need for energy-efficient climate control. However, you cannot capitalize on this demand without your EPA card.
