Do I Need a Refrigerant Identifier?

Use a refrigerant identifier to detect blends and contaminated refrigerant that can harm your service equipment. As low-GWP refrigerants come onto the market with 2013-model-year vehicles, we expect to see contamination issues like we had during the transition from R-12 to R-134a. If you service both light and heavy-duty systems, which will still use 134a, take steps to reduce that risk. If it saves one expensive repair, it’s worth it.
