Automotive HVAC System Market Size, Share, Growth, Trends, and Global Industry Analysis: By Technology (Automatic, Manual), By vehicle type (Passenger Car, Commercial Vehicle, Electric Vehicle, Others), By Component (Compressor, Condenser, Compressor, Receiver-Drier, Expansion Valve, Others), and Region Forecast 2020-2031

Automotive HVAC System Market size was valued at US$ 64,519 million in 2024 and is expected to reach US$ 97,656 million by 2031, growing at a significant CAGR of 6.1% from 2025-2031. This market is projected to grow at a CAGR of 6.5%. An automobile's heating, ventilation, and air conditioning (HVAC) system controls the internal temperature of the vehicle cabin. It consists of three subsystems: heating, cooling, and air conditioning, which work together to supply purified air to the car interior, assuring thermal comfort for drivers and passengers. It regulates the air temperature, checks the moisture content of the air, and removes excess humidity from the circulating air. Well-known brands, such as Audi, Mercedes, and BMW, concentrate on tailored and user-friendly HVAC systems. The industry is seeing moderate expansion because of increased automobile production, increased use of electric vehicles (EVs), and the implementation of stringent vehicle pollution rules.

Furthermore, developments in heating, ventilation, and air conditioning (HVAC) technology, such as increased energy efficiency and eco-friendly systems, are favourably impacting the industry. Some of the significant trends include the development of sophisticated HVAC systems that are linked to the internet of things (IoT) for better user administration, the acceptance of HVAC systems compatible with electric and hybrid vehicles, and the use of environmentally friendly refrigerants. Furthermore, there is a focus on adopting lightweight materials to improve overall vehicle efficiency.

Key Developments:

• In July 2023, Marelli introduced a new Thermal Management Module (iTMM) for EVs, which improves HVAC systems by combining the e-powertrain, battery, and cabin thermal circuits into a single component. This development increased vehicle performance, security, and range by up to 20%.
• On January 5, 2023, Sensata Technologies launched Sensata INSIGHTS, offering comprehensive IoT solutions for workplace and asset monitoring, supply chain and logistics, and telematics.
