In recent years, the cost of HVAC equipment has increased significantly, and regulatory changes, such as the phase-down of R-410A, will make the new A2L units even more expensive.

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.

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

While the refrigerant transition is expected to be relatively smooth due to the alternatives’ similarities to R-410A, dealers should still be aware of its impact on serviceability, product mix, and the HVAC industry overall.

The startup, Pascal, plans to build a better heat pump based on solid refrigerants that will deliver higher efficiencies at lower costs, while eliminating all refrigerant emissions.”

The EPA has finalized SNAP Rule 26, which lists 10 alternative refrigerants as acceptable with use conditions for commercial and industrial refrigeration equipment.

Hudson Technologies and Chemours have agreed to a licensing deal that allows Hudson to sell four types of reclaimed refrigerants under the brand name “Freon.”

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

The EEV is often used in modern refrigeration systems, but troubleshooting its common failures may be complicated.

Keeping a refrigeration system clean and dry by changing the liquid line drier can be the least expensive insurance against compressor failure.
