Which Air Con gas does my vehicle need?
2017 onwards (as a general rule) has seen the exclusive use of the new R-1234yf refriedgerent, adhereing to strict enviromental rules, this new gas is found in all new vehicles. If you are unsure which is required, don not worry, our technicians and advisors will inspect the vehicle and inform you which service is required.
R-134a and R-1234yf are two types of refrigerant used in automotive air conditioning systems. They serve the same purpose – to cool your vehicle – but there are key differences between them.
1. Environmental Impact
R-1234yf was developed as a more environmentally friendly alternative to R-134a. It has a significantly lower Global Warming Potential (GWP). While R-134a has a GWP of 1430, R-1234yf’s GWP is just 4. This means it contributes far less to global warming if it’s released into the atmosphere.
One of the most notable differences between the two is that R-1234yf is mildly flammable, while R-134a is not. However, R-1234yf’s flammability is low and requires special conditions to ignite.
In terms of cooling performance, both refrigerants are quite comparable. They both effectively lower the temperature inside your vehicle.
Vehicles designed for R-1234yf cannot use R-134a. The service fittings for R-1234yf systems are different to prevent cross-contamination of different refrigerants. Furthermore, it’s illegal to put R-134a or any other refrigerant into a car originally equipped with R-1234yf.
R-1234yf tends to be more expensive than R-134a due to its lower environmental impact and the technology used to manufacture it.
In conclusion, while both R-134a and R-1234yf serve the same purpose, they have distinct differences. With the automotive industry’s ongoing commitment to reducing environmental impact, many new cars are being equipped with R-1234yf systems.
