This practical experience allows you to understand the day-to-day aspects of the work while building a professional network.

4. Get an EPA Certificate:

The Environmental Protection Agency (EPA) certificate will ensure compliance with environmental regulations. The EPA certification involves passing an examination covering topics like refrigerant recovery, safety, and recycling procedures. Enhance your skills and credibility by obtaining some other professional certifications.

HVAC Contractor Certifications

Before heading on for the contractor role, you will need some certificates to verify your skills. Out of a bunch of certificates, three major types of HVAC contractor certifications are more important than others.

This is crucial for HVAC technicians who work with refrigerants. The EPA (Environmental Protection Agency) Section 608 certification comes in several types, including Type I, Type II, Type III, and Universal. The specific type depends on the technician’s responsibilities and the types of refrigerants they handle. Technicians must pass an exam related to safe handling, recovery, recycling, and disposal of refrigerants to obtain these certifications.
