Company Backgrounds


  • History and evolution of Mitsubishi
  • Key milestones in the air conditioning industry
  • Reputation and market presence

Mitsubishi, a Japanese multinational conglomerate, has a rich history dating back to the 19th century. Founded in 1870 by Yataro Iwasaki, Mitsubishi started as a shipping company. Over the decades, it expanded into various sectors, becoming one of Japan’s largest and most diversified conglomerates.

During the 60s, Mitsubishi continued to grow, focusing on various sectors such as automotive, electronics, chemicals, and financial services. Mitsubishi Electric became a global leader in electronics and electrical equipment. 

In 1954, Mitsubishi Electric introduced its first air conditioner, marking its entry into the HVAC market. The company launched the “Cooler Unit,” an early residential air conditioning system that set the stage for future advancements in the 60s. In 1987, Mitsubishi Electric pioneered inverter technology, which allowed air conditioning units to adjust their compressor speed dynamically, leading to significant energy savings and improved comfort.

Development of the “Lossnay” heat recovery ventilation system came in 1994, which improved indoor air quality and energy efficiency by recovering heat from exhaust air. At the beginning of the 20th century, they introduced the “Zuba-Central” line, designed specifically for colder climates, offering efficient heating and cooling solutions. In 2020, Mitsubishi continued focus on eco-friendly refrigerants and smart, connected systems to enhance energy efficiency and user control.

Mitsubishi Electric has built a strong reputation and their presence in the market is significant when it comes to the air conditioning industry. They are distinguished by their commitment to innovation, energy efficiency and quality.

Mitsubishi vs Toshiba Aircon


  • History and evolution of Toshiba
  • Key milestones in the air conditioning industry
  • Reputation and market presence

In 1939, Tanaka Seisakusho (by then renamed Shibaura Seisakusho) and Tokyo Electric Company merged to form Tokyo Shibaura Electric Co., Ltd., commonly known as Toshiba. After that the company diversified into various sectors, including heavy electrical equipment, consumer electronics as well as home appliances.

During the 1930s, Toshiba started exploring air conditioning technologies in conjunction with its broader electrical and mechanical engineering advancements. In 1961, Toshiba launched its first window air conditioner, marking its entry into the consumer air conditioning market. In 1968, Toshiba developed the world’s first rotary compressor, a significant innovation that can enhance the efficiency and reliability of air conditioning units.

 During the 1980s, Toshiba introduced the world’s first inverter-driven air conditioner and an advanced split-type air conditioner, which separated the compressor and evaporator units for more efficient cooling and quieter operation. In 2012, ​​Toshiba introduced hybrid inverter technology, combining both direct current (DC) and alternating current (AC) inverters for enhanced performance and energy efficiency.

Today, Toshiba continues to focus on infrastructure, energy, and electronic devices, aiming to leverage its strengths in these areas for future growth. From pioneering inverter technology to developing eco-friendly and smart air conditioning systems, Toshiba continues to lead the market with a focus on efficiency, sustainability and performance.
