Roadchill is now offering a full r1234yf re-gas and repair service. This runs alongside the existing r134a service. R1234yf is the new A/C refrigerant which is replacing r134a. Some cars built in 2012 and onwards have r1234yf and new cars from 2017 will use the new gas. Due to the high cost of r1234yf leak detection and repair is extremely important, at Roadchill we pride ourselves in finding leaks first time and finding leaks where others have failed.
