Air Conditioning Recharge and Service

How do I know which air con gas I require?

R134a refrigerant is common in vehicles manufactured before 2015. A new more environmentally friendly vehicle air conditioning system refrigerant gas (known as R1234yf) has become widely used (instead of R134a) from the 1st January 2017 on passenger cars and Light Goods Vehicles (LGVs) up to 3.5 Tonnes.  For example, if R134a gas was released into the atmosphere, it had a lifespan of 13 years in comparison to just 11 days for R1234yf refrigerant.

R1234yf refrigerant  was phased in by vehicle manufacturers over time so vehicles rolling off the production line between 2014 and 2016 could require either gas. The same time rule applies to HYBRID and EV vehicles – they can have systems running either R134a or R1234yf depending on time of manufacture. All EV/HYBRID vehicles manufactured since 1st January 2017 use the new R1234yf air con refrigerant however EV/HYBRID cars  ALWAYS require specialist AC machines that run non-conductive PAG oil as the AC compressor is operated using High Voltage DC power .

GG MOTORS Autocare offers AC services and repairs on following systems:

  • R134a refrigerant (Pre 2017 vehicles)
  • R1234yf refrigerant (2017 onwards  vehicles)
  • R134a HYBRID/EV AC service using dedicated equipment and non-conductive PAG oils
  • R1234yf HYBRID/EV AC service using dedicated equipment and non-conductive PAG oils

If there are bad odours coming from your air vents when you turn on your car AC, then your car may also benefit from an air con clean, also known as a debug. Over time bacteria, mould and fungi can build up on the evaporator in your air con system which produces this unpleasant smell when switched on. In some cases this can cause sickness and respiratory problems as bacterial spores are blown into the cabin of the vehicle and breathed in by the passengers.

GG MOTORS Autocare offers an air conditioning disinfection to decontaminate the system and kill the bacteria within. The process involves spraying antimicrobial chemical agent into the system that kills off the unwanted bacteria within, leaving your vehicle air conditioning system clean and smelling fresh again.

An air con debug is available as an optional extra when you have your air conditioning recharged at GG MOTORS Autocare. Please contact us for details and latest pricing information.
