Since 1921, Mitsubishi Electric has pursued a single ambition: to translate fundamental science into products that make people's lives measurably better. HVAC is one of four core businesses — but it's the one that touches every building, every climate zone, and every type of occupant on the planet.
Mitsubishi Electric Corporation was founded as a spin-off from Mitsubishi Shipbuilding, initially focused on electric motors and ship fans. The engineering DNA of precision electro-mechanical systems has been central to the company's identity ever since.
Mitsubishi Electric launches the first room air conditioner marketed specifically for residential use in Japan. The product redefines the category by prioritising quiet operation and ease of installation — values that remain defining characteristics of the brand today.
The Mr. Slim series launches as the world's first commercially available ductless split-system air conditioner. The separation of outdoor compressor from indoor air handler — connected only by refrigerant piping — becomes the foundational architecture for the global ductless market.
The Diamond Contractor network creates a certified installer ecosystem with factory training, technical support infrastructure, and extended warranty activation capability. The programme grows to over 4,000 North American contractors and becomes the model for similar programmes in Europe and Australia.
The H2i enhanced vapour injection compressor platform achieves verifiable heating operation at −25°C, making all-electric home heating practical for the first time in ASHRAE Climate Zones 5–7. This breakthrough catalyses the North American heat pump electrification movement that accelerates significantly following the 2022 Inflation Reduction Act.
Mitsubishi Electric completes the global transition of all residential mini split and heat pump product families to R-32 refrigerant (GWP 675, vs 2,088 for R-410A), ahead of European F-gas regulation timelines and in alignment with the Kigali Amendment HFC phase-down schedule. Work continues on ultra-low GWP refrigerant validation for future platforms.
Mitsubishi Electric operates manufacturing and R&D facilities across Japan, the United States, Europe, and Asia Pacific. HVAC design and engineering is based in Minami-Ku, Kobe (Japan) and Alpharetta, Georgia (North America), with regional technical centres in over 30 countries.
