Why switch to R134a gas?

R12 refrigerant, once a staple in car air conditioning systems, has been phased out due to its harmful environmental impact.

At Mark 4, we understand the importance of keeping your car cool while doing your bit for the planet. Our R12 to R134a gas conversion service is designed to help you transition seamlessly, ensuring your air conditioning system is up to date and compliant with current standards.
