Can technicians create EPA-approved refrigerant blends?

• A. Yes
• B. Not allowed
• C. Only with special EPA approval
• D. No

Answer: (D)

The main idea is that EPA approval for refrigerant blends is handled through a formal listing process that is done by manufacturers, not by technicians in the field. To be sold and recognized as an EPA-approved refrigerant, a blend must be developed, tested, and submitted by a licensed manufacturer, then reviewed and listed by the EPA. Technicians aren’t authorized to create new blends or obtain EPA approval on-site; mixing up refrigerants to form a new blend would result in an unlisted substance with unknown properties and could violate environmental and safety regulations. Therefore, you should rely only on refrigerants that are already EPA-approved and listed.
