What type of systems are technicians certified to recover refrigerant from after passing the small appliance examination?

Technicians who have passed the small appliance examination are authorized to recover refrigerant specifically from packaged terminal air conditioners that have 5 pounds or less of refrigerant. This regulation ensures that those certified can safely handle smaller appliances, which are common in residential and small business settings.

The focus of the small appliance certification is on the equipment that falls under this category, allowing technicians to deal with certain types of air conditioning systems without needing additional certifications for larger systems or different refrigerant types. This is essential for maintaining environmental standards and minimizing the release of refrigerants into the atmosphere.

Other options may involve larger systems or different equipment types that require additional training and certification, which fall outside the scope of the small appliance examination.
