Yamato Optimum Air Conditioner

Yamato Optimum is a wall-mounted ductless mini-split air conditioning unit marketed primarily in European markets, particularly in Eastern and Southeastern Europe (such as Romania). The brand Yamato in the HVAC sector is owned and distributed by the Romanian HVAC distributor and solutions company Aser Vio Term / Romstal Group.

While the branding evokes Japanese associations through its name, the air conditioning units are manufactured by leading original equipment manufacturers (OEMs) in China, such as Gree Electric Appliances or AUX Group, which supply private-label climate control appliances globally.
