With A2L refrigerants, leak prevention and detection matter more than ever, so technicians should follow best practices and use the right tools to find and fix leaks.  

Choosing the right refrigeration system isn’t one-size-fits-all — it requires a careful look at performance, cost, and the unique demands of each project. 

An international team of researchers has developed porous plastic sheets that can lower building temperatures through radiative cooling. 

Advanced HVAC technologies are supporting the A2L refrigerant transition by improving system efficiency, safety, and reliability. 

Collaboration and teamwork led to the successful design and installation of Canada’s first ice rink to use an A2L refrigerant.  

Researchers at Johns Hopkins have developed a new energy-efficient technology that is an alternative to traditional compressor-based refrigeration. 

Following best practices when cleaning and repairing leaks is crucial in systems with microchannel condensers. 

According to the lawsuit complaint, Brian Mierendorf, 37, was asked to service the refrigeration lines within a Kroger in Michigan. The lawsuit stated that during maintenance, a refrigeration line began spraying liquid refrigerant into the store. 

The HVACR industry is in the thick of a major refrigerant transition — and R-454B is suddenly in short supply. Why is one new refrigerant hard to find while another isn’t? What can contractors do when demand is surging, supply is tight, and customers are sweltering? Here, experts break down the manufacturing missteps, shifting pressures, and real-world solutions.
