Manufacturers are launching a wide range of A2L equipment, and with proper training and adherence to best practices, HVAC contractors can confidently address the challenges of working with mildly flammable refrigerants.
Starting in 2025, most new comfort cooling systems will use lower-GWP, mildly flammable refrigerants, which include a safety feature called the refrigerant detection system (RDS), which detects leaks and can be factory or field installed.
Technicians must be trained to handle A2L refrigerants safely, using proper equipment, following safety guidelines, and understanding risks to prevent injuries.
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.
Manufacturers are starting to introduce their A2L systems in the U.S., so contractors and technicians must learn how to service and install this new equipment.
