Some car manufacturers now use a newer type of refrigerant called R1234YF. This change is driven by its significantly lower Global Warming Potential (GWP) compared to the older R134a refrigerant, making it a more environmentally responsible choice for modern vehicles.

At West Coast Auto Airconditioning, our technicians are fully trained and experienced in working with vehicles that use R1234YF systems. We keep R1234YF refrigerant in stock, ensuring faster turnaround times and helping you get back on the road sooner. Our team stays up to date with the latest equipment, diagnostic methods, and repair procedures required for both R134a and R1234YF systems.

⚠️ Important Note

Vehicles designed for R134a refrigerant cannot be safely or legally converted to use R1234YF. The systems are engineered differently, and attempting to retrofit can create safety risks, system damage, or regulatory issues.

❓ FAQ: How Can I Tell Whether My Car Uses R134a or R1234YF?

1. Check the Refrigerant Label Under the Bonnet

Every vehicle has an A/C system information sticker under the bonnet.
It will clearly list either R134a or R1234YF.

2. Look for the Service Port Design

R1234YF systems use different service port fittings to prevent cross-contamination.
A technician can identify the refrigerant type instantly by checking these ports.

3. Refer to Your Owner’s Manual

Your vehicle’s manual will state the correct refrigerant type used from factory.

4. Ask a Qualified Technician

If you’re unsure, we can check the system for you during an inspection at our workshop.

5. Don’t Rely Solely on Vehicle Age

The switch to R1234YF varies by brand, model, and market.
Some manufacturers adopted it earlier, while others continue using R134a today.
The only accurate way to know is by checking the vehicle label or fittings.
