Market Growth Factors

The​‍​‌‍​‍‌​‍​‌‍​‍‌ automotive HVAC systems market is majorly influenced by consumer demands for improved comfort inside the vehicle and safety features. Besides, the worldwide trend towards electric vehicles (EVs) is putting emphasis on the need for HVAC systems that cool the battery efficiently and thus, maintain its performance, given that around 14 million new EVs were recorded around the globe in 2023 and there is a total of approximately 40 million EVs on the roads. Consequently, automakers are under pressure to come up with specially designed HVAC systems for EVs and HVs that feature energy-saving elements like heat pumps and energy recovery units. 

Moreover, tough government regulations on emissions and energy use of vehicles have brought manufacturers to the point of coming up with eco-friendly refrigerants and advanced compressor technologies. Light GWP refrigerants and features such as a variable displacement compressor contribute to the efficient use of energy and at the same time, the lessening of a negative impact on the environment. Such innovations are a necessary step toward fulfilling regulatory requirements and keeping the market sustainable. 

Furthermore, developments in smart automotive HVAC solutions, like automatic climate control, IoT integration, and sensor-based climate regulation, to mention a few, are making the passenger's life easier and the system more efficient. All these aim at minimizing energy consumption and maximizing convenience by providing automatic and very accurate environmental adjustments. Soft money from R&D undertaken by big automotive players helps the pace and extent of the ongoing HVAC system revolution as well.
