What Refrigerant is Used in Cars in 2025?
The automotive industry has seen significant advancements in technology and environmental regulations over the years. One area of change involves the refrigerants used in car air conditioning systems. Refrigerants play a crucial role in cooling vehicle cabins, but as global environmental concerns grow, the industry has shifted toward more eco-friendly options.
If you’ve ever asked, “what refrigerant is used in cars in 2025?”, this guide by Royal Refrigerants is here to provide clear answers. From the most commonly used refrigerants to emerging trends, you’ll learn how these cooling agents are evolving and what they mean for your vehicle.
The Role of Refrigerants in Car Air Conditioning Systems
Refrigerants are indispensable to your vehicle's air conditioning system, enabling it to maintain a cool and comfortable cabin temperature. These chemical compounds absorb and release heat during the cooling process, making them the key to your AC system's functionality. Whether you’re driving through scorching heat or muggy conditions, a properly functioning refrigerant ensures your comfort and safety.
The type of refrigerant your AC system uses also determines its efficiency and environmental impact. Over the years, advancements in refrigerant technology have resulted in compounds that are more energy-efficient and eco-friendly, minimizing harm to the environment while maintaining high performance. Understanding the role refrigerants play in your vehicle’s cooling system is essential for maintaining its longevity and efficiency.
As global regulations tighten and new standards emerge, the choice of refrigerant has become more than just a technical consideration. It now reflects a commitment to environmental sustainability and compliance with international guidelines, making it vital for car owners to stay informed.
How Refrigerants Work in Car AC Systems
Refrigerants circulate through the car's AC system, transitioning between liquid and gaseous states to absorb and dissipate heat. The process begins with the refrigerant in a low-pressure gaseous state. As it flows through the compressor, it becomes a high-pressure gas, which is then cooled in the condenser and turned into a high-pressure liquid.
This liquid refrigerant flows into the evaporator, where it absorbs heat from the car’s interior, cooling the cabin. The cycle then repeats, providing consistent cooling.
Why the Type of Refrigerant Matters
The type of refrigerant used directly impacts the system's efficiency and environmental footprint. Some refrigerants, like the older R-12, have been phased out due to their ozone-depleting properties, while others, such as R-134a, have been replaced by more sustainable options with lower global warming potential (GWP).
Common Refrigerants Used in Cars in 2025
To answer “what refrigerant is used in cars”, the most common one is R-1234yf, which has become the industry standard due to its eco-friendly properties.
However, some vehicles still use other refrigerants depending on their model year and system design.
Understanding these refrigerants helps car owners and automotive professionals make informed decisions when servicing or retrofitting AC systems.
R-1234yf: The Modern Standard
R-1234yf is the leading refrigerant for automotive air conditioning systems in 2025. Introduced as a replacement for R-134a, it has a significantly lower GWP and complies with environmental regulations set by governments worldwide.
This refrigerant is compatible with modern AC systems, offering excellent cooling performance while minimizing its impact on the environment. Its widespread adoption has made it the go-to choice for car manufacturers and repair shops alike.
R-134a: Still in Use for Older Models
Although R-1234yf dominates the market, many older vehicles still use R-134a. This refrigerant was the industry standard before the transition to R-1234yf and remains a viable option for cars that have not been retrofitted.
While R-134a is more environmentally friendly than its predecessor R-12, it still has a higher GWP than R-1234yf. As a result, it’s being phased out in favor of more sustainable alternatives.
Emerging Trends in Automotive Refrigerants
The automotive industry is constantly evolving, and refrigerants are no exception.
As environmental concerns continue to drive innovation, new refrigerants and technologies are being developed to improve efficiency and sustainability.
Understanding these trends helps car owners stay informed about the latest advancements and prepare for future changes in automotive cooling systems.
The Rise of Natural Refrigerants
Natural refrigerants, such as carbon dioxide (CO2), are gaining attention as eco-friendly alternatives to synthetic options like R-1234yf. Known as R-744 in the refrigerant industry, CO2 has a GWP of just 1, making it one of the most environmentally friendly refrigerants available.
Some manufacturers are exploring CO2-based systems for specific applications, particularly in regions with strict environmental regulations. However, these systems require specialized components and are not yet widely adopted.
Innovations in Cooling Technology
Beyond knowing what refrigerant is used in cars, advances in cooling technology are shaping the future of automotive air conditioning. For example, electric vehicles (EVs) often use heat pump systems that can heat and cool the cabin more efficiently than traditional AC systems.
These innovations, combined with the adoption of low-GWP refrigerants, are helping the automotive industry reduce its environmental footprint while maintaining performance.
Retrofitting and Servicing AC Systems
As regulations phase out older refrigerants like R-134a, retrofitting becomes an important consideration for car owners.
Retrofitting an AC system involves modifying its components to make it compatible with newer refrigerants such as R-1234yf. This ensures compliance with environmental standards while improving system performance and extending its lifespan.
Retrofitting is especially relevant for owners of older vehicles that were originally designed to use R-134a. The process includes replacing parts like the compressor, hoses, and seals to ensure the system can handle the properties of the new refrigerant. While retrofitting requires an upfront investment, it offers long-term benefits by improving energy efficiency and reducing emissions.
When servicing an AC system, using high-quality refrigerants is critical. Low-quality or counterfeit refrigerants can harm your system, leading to expensive repairs and reduced performance. Working with trusted suppliers like Royal Refrigerants ensures that your vehicle’s cooling system remains reliable and compliant with current standards.
Retrofitting Older Vehicles
Retrofitting involves replacing certain components of the AC system, such as the compressor, condenser, and hoses, to ensure compatibility with the new refrigerant. While this process requires an upfront investment, it can extend the life of the vehicle and provide better cooling performance.
Professional service providers, like those partnered with Royal Refrigerants, can handle the retrofit process and recommend the best refrigerant for your vehicle’s needs.
The Importance of Using High-Quality Refrigerants
When servicing or recharging your AC system, using high-quality refrigerants is essential for optimal performance and durability. Low-quality or counterfeit refrigerants can damage your system, leading to costly repairs.
