The first step to recharging your car’s air conditioning is knowing what type of refrigerant it needs. While this can be daunting at first, there’s no need to fret; A/C Pro® has the tools to help you understand if your vehicle uses R-134a or R-1234yf refrigerant.

Most vehicles have a label or sticker under the hood that indicate whether the refrigerant used is R-134a or R-1234yf. However, not all cars have this.

If not, visiting the A/C Spec Database available through our Port Finder page will help you figure out what type of refrigerant your car needs. Simply enter the car’s year, make, model, and engine and the database tool will bring up the exact information you need.

If you need more help, or if you prefer watching to reading, we have a video that walks you through the steps that will point you in the right refrigerant direction.

Still worried about whether you have selected the correct refrigerant?

There’s no need to be. A/C Pro®’s recharge kits and accessory gauges have snap-lock couplers that only work with the correct type of refrigerant. This prevents R-134a from being put into a system that requires R-1234yf, and vice-versa.

Be sure to check out A/C Pro®’s full line of products for R-134a and R-1234yf vehicles.

R-134a vs R-1234yf

Curious as to what the difference is between R-134a and R-1234yf? In short, manufacturers are continually seeking ways to create more environmentally-friendly gases that are used in vehicular applications.

A few decades back, R134a replaced the refrigerant called „R-12,“ commonly referred to as „Freon.“ R-1234yf is an even more environmentally-friendly gas than R-134a and has been making its way into some cars since 2013.
