What certification is needed specifically for handling small appliance refrigerants?

The Universal certification is required for individuals who handle refrigerants in all types of systems, including small appliances. This certification grants the holder the ability to work with any type of refrigerant and any type of equipment, which encompasses small appliances such as household refrigerators, window air conditioners, and similar units. Obtaining Universal certification ensures that the technician has been trained on the proper handling, recovery, and disposal of refrigerants in accordance with EPA regulations, making it essential for those working on any HVAC system, large or small.

In contrast, the other certifications focus on specific categories of equipment. Type I certification is limited to small appliances, while Type II is aimed at high-pressure systems, and Type III is for low-pressure systems. Therefore, while Type I would allow a technician to handle small appliance refrigerants, the Universal certification encompasses that capability and much more, providing a broader scope of practice.
