New vehicles from early 2017 will use the new refrigerant R1234yf in their air conditioning systems instead of the old refrigerant R134a. Air conditioning systems with the new chemical must be maintained as regularly as those with conventional R134a. The difference: the technology and refrigerant are significantly more expensive than the old R134a. This translates to a higher price for air conditioning maintenance. We can maintain, recharge, and repair R1234yf air conditioning systems. We have the appropriate technology and know-how.
