I some time ago had my car's air conditioning system serviced, when the car was 2.5 years old. It was functioning okay, but I opted for the service because I wanted to have a measurement of the refrigerant loss. The receipt I have says:
- Recovered refrigerant 437 g
- Removed oil 3 g
- Added refrigerant 530 g
- Added oil 3 g
So, 93 g of refrigerant was lost. In other words: in 2.5 years, 17.5% of refrigerant was lost. This gives a refrigerant loss rate of 7% per year.
My questions are:
- Should I be worried about 7% refrigerant loss per year?
- How often based on this refrigerant loss rate, should I have my AC system serviced?
The car is a 2016 Toyota RAV4 hybrid.
