【Air Conditioner Refrigerant Maintenance for Imported Cars｜Supports R1234yf and R134a】

When you feel that the air conditioner is not cooling as effectively as before or it takes longer to reach the desired temperature, it’s worth checking the amount and condition of the A/C refrigerant.

In recent imported vehicles and new models, the number of cars using the new refrigerant R1234yf (HFO-1234yf)—instead of the conventional R134a—has been increasing. Since the refrigerant type can’t be identified just by appearance, it’s important to first confirm which gas is suitable for your vehicle.

At LOGON, we use A/C refrigerant maintenance equipment that supports both R134a and R1234yf. Because we can switch according to the refrigerant type, we can perform maintenance tailored to your vehicle while managing it so that different gases do not mix.

What You Can Do with A/C Refrigerant Maintenance

As you use the air conditioner, the refrigerant may gradually decrease or moisture and impurities may mix inside.

Using dedicated equipment, we recover the refrigerant from the vehicle, check its condition, and then replenish the required refrigerant and oil in the proper quantities. Instead of simply adding refrigerant, recovering it once and restoring its condition makes it easier to confirm that the air conditioner is working as it should.

The equipment we use is equipped with patented technology that removes impurities in the gas up to 99.99%. Especially for vehicles that use the expensive R1234yf, the advantage is that you can perform the work with precise control while preventing unnecessary refrigerant consumption.

Please Contact Us Even If You’re Not Sure Whether It’s R1234yf or R134a

Even if you purchased the vehicle new, it’s not unusual that you may not have been given a detailed explanation of the refrigerant type. If you’re unsure whether your vehicle supports R1234yf, we will guide you after checking your vehicle information.

However, weak cooling is not caused by refrigerant quantity alone. Other issues—such as refrigerant leaks, the compressor, or sensor-related problems—may be hidden as well.

Therefore, if I were doing it, I would not just “add refrigerant for now.” I would first check the vehicle’s condition and then perform maintenance. If no improvement is seen after the work, I will honestly tell you that additional inspection may be necessary.

A/C Refrigerant Maintenance at LOGON

Because the refrigerant and required quantity vary by vehicle model, it’s important to perform A/C refrigerant maintenance using the correct equipment and proper settings for the vehicle.

At LOGON, we check the vehicle information—including imported cars—determine whether it supports R1234yf or R134a, and then carry out the work. To help you use your valuable car comfortably for a long time, we carefully check each vehicle one by one while also asking about how well it cools and your usage conditions.

It’s reassuring to have it inspected once when you notice even a slight difference in cooling, rather than rushing after the air conditioner stops working properly during the hot season. If you provide details such as the vehicle model and model year, we will confirm whether we can handle it and then guide you.

Now, we will continue to respond properly so you can enjoy a comfortable drive.
