History
AUX traces its origins to 1986 in Ningbo, Zhejiang, where the business that later developed into AUX Group began as an industrial enterprise. The group’s early development was connected with electrical equipment and manufacturing. Over time, it broadened its business scope and developed a recognizable consumer brand, with air conditioning becoming its most important and visible product category. The expansion into air conditioners placed AUX in China’s rapidly growing home-appliance market. Demand for residential cooling, urban housing, commercial construction and replacement appliances created room for large domestic manufacturers with extensive production and distribution capabilities. AUX built its market presence through a combination of manufacturing scale, dealer networks and products targeted at practical household needs. Its principal competitors included other large Chinese appliance producers as well as established overseas brands. During the following decades, AUX developed a wider portfolio around heating, ventilation and air conditioning. Residential split systems remained central, while multi-split, light commercial and commercial applications broadened the potential customer base. Product development increasingly incorporated inverter compressors, energy-saving controls, air purification, remote operation and smart-home connectivity. These features reflected wider changes in the appliance industry, in which connected devices and lower energy consumption became important purchase considerations. The wider AUX Group also diversified beyond consumer appliances. Its activities have been associated with electrical equipment, medical services, real estate and other businesses. This diversification means that AUX Group and the AUX consumer brand are related but not identical concepts: the brand most visible to household consumers is principally associated with air conditioners and appliances, whereas the group has had a broader corporate scope. AUX has also sought overseas growth. Air-conditioning products have been marketed outside China through a combination of export sales, distributors, local partners and regional channels. International presence has developed across parts of Asia, the Middle East, Africa, Europe and Latin America, although the depth of local operations and product availability differs by country. In these markets, the brand generally competes on product range, pricing, energy performance and distribution support. The company’s public profile has periodically been affected by the competitive and regulatory environment of China’s appliance industry. Air-conditioner manufacturers face scrutiny concerning energy-efficiency claims, product standards, advertising, quality and after-sales service. AUX has also competed in a market where brands use sports sponsorships, retail promotions, online commerce and technology messaging to gain attention. Such activities are part of normal category competition and should not be treated as evidence of a separate corporate entity or a particular legal event without case-specific documentation. Today, AUX remains an active Chinese appliance brand with air conditioning at its center. It is best understood as a brand operated within the broader AUX Group rather than as an independently documented global corporation. Precise information about current executives, subsidiaries, revenues, listings and market shares requires consultation of current official filings or company announcements.

Home appliances
Residential split air conditioners
AUX’s core consumer line consists of wall-mounted and other residential split air-conditioning systems. These products are designed for household cooling and, depending on the market and model, heating, dehumidification, sleep modes, self-cleaning, air-quality functions and remote control. The range spans accessible mainstream products and more feature-rich inverter models.
Heating, ventilation and air conditioning
Inverter air conditioners
Inverter models regulate compressor output rather than operating only at fixed capacity. AUX markets this category around lower operating energy, temperature stability and quieter comfort. Specific efficiency ratings, refrigerants, controls and certifications vary by model and jurisdiction, so claims should be checked against the relevant local specification.
Commercial HVAC
Multi-split and commercial HVAC systems
AUX also supplies systems for multiple indoor units, small commercial premises and other applications requiring more complex climate control than a single residential split unit. These products extend the brand into contractor, property and commercial channels and may involve professional design, installation and maintenance.
Household appliances
Air-treatment and smart-home appliances
The broader AUX appliance portfolio has included air-treatment and connected-home products. Depending on market availability, these may include air purifiers and appliances with app-based monitoring or control. Product names and specifications are not uniform across countries.
