Why R-1234yf Matters (and Why Your 2017 NQR Uses R-134a)
You might have heard about a newer refrigerant called R-1234yf and wondered if your 2017 Isuzu NQR uses it. The transition from R-134a to R-1234yf began around 2014 for many passenger vehicles due to environmental concerns. R-1234yf has a much lower Global Warming Potential (GWP) than R-134a, making it more eco-friendly. However, commercial vehicles like your Isuzu NQR often adopt new technologies at a different pace. For the 2017 model year, the Isuzu NQR continued to use R-134a. This is good news in some respects, as R-134a is generally less expensive, and the equipment required for servicing is more readily available and less costly than for R-1234yf.
If your Isuzu NQR were equipped with R-1234yf, you'd face higher refrigerant costs, more specialized (and expensive) recovery and recharge equipment, and stricter handling procedures mandated by environmental regulations.
