Counterfeit refrigerants have been in the news a lot lately, as manufacturers contend that record amounts of illegal imports of HFCs are being brought into the U.S. under the radar of customs. While some of these imported refrigerants may be of the correct composition, there is evidence that others may be counterfeit or of low quality.

Mixed refrigerants are another problem that contractors frequently encounter in the field, and they are also a huge concern. Not only can mixed and low-quality refrigerants damage HVACR systems, they can pose a safety threat to technicians who are servicing the equipment, particularly if a flammable or toxic component is involved.
