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.

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

In the second installment of this series, the topic of flammability is addressed. We ask Chemours technical trainer Don Gillis what steps contractors should take to mitigate the risk of ignition when working with A2L refrigerants.

In comments to EPA’s proposed rule regarding HFC management, many HVACR stakeholders expressed concern over issues including tracking cylinders, training technicians, and reclaiming refrigerant.

As more and more case-controlled facilities turn to CO₂ refrigeration, HVAC contractors are tasked with adequately educating themselves on these systems so that they can meet the country’s budding installation and service needs.

While CO₂ refrigerant may not be as deadly to the environment as its HFC peers, there are other concerns that exist when it escapes a system.

Compressors in A2L systems are similar to A1 systems, so technicians won't need extensive retraining, especially if they follow best practices.

Some food retailers express concerns over CO₂ refrigeration systems, which they have found to be leaky and less energy efficient than expected.

Manufacturers have been preparing for the transition to low-GWP refrigerants for a number of years and are now introducing a wide range of innovative commercial refrigeration technologies.

HVAC contractors and technicians must invest in new spark-free tools that are compatible with the A2L refrigerants.
