Technician certification required for sealed-system service on small appliances?

For sealed systems on small appliances, the needed credential is Type I, and you can also qualify with Universal certification since it includes Type I. Small appliances are defined as those with less than 5 pounds of refrigerant and are serviced under Type I. Type II covers high‑pressure appliances, and Type III covers low‑pressure appliances, so they don’t apply to these small sealed systems. No certification isn’t allowed for handling refrigerants, and Universal is acceptable because it encompasses all three categories.
