Since A2L refrigerants are designated as mildly flammable, safety features like refrigerant detection systems (RDSs) are being incorporated into new residential/light commercial ducted split systems that contain more than 4 pounds of A2L refrigerant. Here’s what HVAC technicians need to know about installing those RDS in the field.

RDSs are generally required in A2L systems that contain more than 4 pounds of refrigerant and can either be field or factory-installed, depending on the manufacturer.

Soap bubbles have long been thought of as the standard method for leak detection, but times, and technology, are changing.

Home builders need to begin preparing for the big refrigerant shift that is quickly approaching.

In the third installment of this series, we ask Chemours technical trainer Don Gillis if leak detection methods should change with A2L refrigerants.

A refrigerant detection system (RDS) will be required for all A2L systems in occupied spaces exceeding a specific refrigerant charge limit.

At a recent GreenChill webinar, the experts from DC Engineering provided insights on how to create a strategic leak reduction and refrigerant management plan.

Servicing new reach-in coolers and freezers containing R-290 is not tremendously difficult but does require some different servicing procedures.
