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. 

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.  

Short on R-454B? Don’t risk mixing refrigerants — doing so could jeopardize safety, system performance, and your reputation.

The R-454B shortage has caught much of the HVAC industry off guard. Here's how contractors can make the best of a tough situation.
