Essential Federal Certification: EPA Section 608 Universal
Before you can legally handle refrigerants in any state, including Washington, you must obtain your EPA Section 608 certification. This federal requirement isn’t optional – it’s mandatory for anyone working with HVAC systems containing refrigerants.

A Word of Caution About Drug Testing
Before you begin your HVAC career journey, there’s an important reality I need to share from my years in trades education and industry. With marijuana being legal in Washington State, I’ve seen many aspiring tradespeople derail their careers before they even got started.
I’m not here to tell you what to do with your personal life, but if you’ve read this far, you’re probably serious about joining the HVAC trade. If you want the opportunity to work for the best organizations possible, I’m going to tell you now: they are going to drug test you, and probably randomly throughout your employment.
While having a clean drug test isn’t technically a licensing requirement, it’s something I would highly recommend if you’re serious about this career path. The top-paying HVAC companies, union apprenticeships, and commercial contractors all maintain strict drug-free workplace policies. Many also work on federal projects or with insurance companies that require these standards.
This isn’t just about getting hired – it’s about building a sustainable, long-term career in a field that can provide excellent income and job security. The choice is yours, but I’ve seen too many promising students and workers lose opportunities because they weren’t prepared for this reality of the trades.
