HVAC EPA 608 Certification Review & Exam
The Federal Clean Air Act, Section 608, requires that persons who service air conditioning and refrigeration systems containing certain regulated refrigerants be certified under an approved Federal Environmental Protection Agency (EPA) course. Through the ESCO Institute, Chadwell Supply is able to offer this Universal Certification. Only certified technicians may purchase any regulated refrigerants or precharged part with a regulated refrigerant from Chadwell Supply or other HVAC suppliers.
