The short answer is that the exact amount depends on the Santa Fe’s model year and the refrigerant type. In general, older Santa Fe models using R-134a require about 28–32 ounces (0.8–0.9 kilograms) of refrigerant, while newer models using R-1234yf typically need roughly 20–28 ounces (0.6–0.8 kilograms). Always verify the precise charge on the vehicle’s service label or in the owner’s manual.
What follows breaks down typical capacities by refrigerant type and explains how to confirm the exact charge for your specific vehicle. The system’s capacity is engineered for optimal cooling and compressor efficiency; charging outside the specified range can reduce performance or damage components. Hyundai transitioned from R-134a to R-1234yf on recent Santa Fe generations, which affects both the required amount and the servicing procedure.
Refrigerant capacity by type
R-134a vs. R-1234yf
Before listing typical ranges, it’s useful to note that the Santa Fe has used two refrigerants across its generations. R-134a is common in earlier models, while R-1234yf is used in many newer vehicles. Each refrigerant has its own charge specification and service requirements.
- R-134a equipped Santa Fe (older generations, roughly 2007–2018): about 28–32 oz (0.8–0.9 kg).
- R-1234yf equipped Santa Fe (newer generations, roughly 2019–present): about 20–28 oz (0.6–0.8 kg).
These ranges provide a practical guide for shop conversations and roadside checks. The exact value for your car will depend on the engine, trim, and whether any factory options affect the A/C system. Always rely on the official capacity listed on the vehicle’s service label or in Hyundai’s documentation.
How to verify the exact capacity for your Santa Fe
To ensure you use the correct amount of refrigerant, follow these steps to locate the precise specification for your vehicle:
- Check the A/C service label under the hood (usually on the radiator support or near the hood latch). The label lists the refrigerant type (R-134a or R-1234yf) and the required charge in ounces or kilograms.
- Consult the owner’s manual or Hyundai’s official service information portal for your model year and engine configuration to confirm the exact specification.
- Have a qualified HVAC technician perform the recharge with a calibrated refrigerant scale and vacuum pump to ensure the correct charge and leak testing.
Correct charging protects cooling performance and system longevity. If you suspect a leak or the system is not cooling properly, address those issues before attempting a recharge.
Summary
In short, Hyundai Santa Fe refrigerant capacity varies by model year and refrigerant type. Expect roughly 0.8–0.9 kg (28–32 oz) for R-134a models and about 0.6–0.8 kg (20–28 oz) for R-1234yf models. For the exact amount, always verify with the vehicle’s service label or owner’s manual, and if in doubt, have an HVAC professional perform the service with proper equipment.
Is 4 lbs of refrigerant a lot?
It is essential to ensure enough refrigerant in your air conditioner, as too little can cause the system to work less efficiently, and too much can be dangerous. The general guideline used when calculating the amount of Freon in a residential A/C unit is 2-4 pounds per ton of cooling.

Hyundai Santa Fe AC Gas Capacity by Year
For older models, typically those from the early 2000s, the AC gas capacity is often around 22-28 ounces (624-794 grams) of R-134a refrigerant.
How many 12 oz cans of Freon do I need?
How many cans of Freon does a car take / how many Freon cans do I need. Most standard passenger vehicles require around 1 to 2 pounds of Freon, depending on system size and leak levels. That means between 1.5 to 3 cans of 12 oz. But these are rough estimates—always confirm using a proper refrigerant gauge.
