Mitsubishi Heavy Industries Air Conditioner

Mitsubishi Heavy Industries (MHI) is a cornerstone of Japanese engineering, evolving from the original Mitsubishi group established in the 19th century. The air conditioning division specializing in residential and commercial thermal systems is a major global player. While the brand is quintessentially Japanese, the majority of their split-system air conditioners are manufactured in Thailand at their Mitsubishi Heavy Industries-Mahajak Air Conditioners (MACO) facility, though they maintain high-end production in Japan for specific markets.

The global ownership remains under Mitsubishi Heavy Industries, Ltd., headquartered in Tokyo. It is important to distinguish MHI from Mitsubishi Electric, as they are separate corporate entities following the post-WWII reorganization. MHI continues to be a leader in heavy machinery and climate control technology throughout 2026.
