Safety note: never mix refrigerants or use unapproved refrigerants. The correct refrigerant and service process should be confirmed by vehicle label, service information, and proper equipment.
What R-134a and R-1234yf mean
R-134a and R-1234yf are refrigerants used in motor vehicle air conditioning systems. Many older vehicles use R-134a, while many newer vehicles use R-1234yf.
The refrigerant type is not something to guess. It should be confirmed from the vehicle label, service information, and the exact year, make, and model.
Why the correct refrigerant matters
Different refrigerants require the correct service process and compatible equipment. Mixing refrigerants or using the wrong product can reduce cooling, contaminate equipment, or create safety concerns.
If your A/C is warm, the first step should be confirming the system condition and refrigerant type before adding anything.
What to ask before A/C service
Ask whether the shop will verify the correct refrigerant for your vehicle and test the system before recommending a recharge or repair.
AAB Service identifies the vehicle-specific refrigerant requirement and uses a diagnostic process before repair recommendations.
