As the industry continues to evolve, it’s essential for HVACR contractors to embrace comprehensive training programs that address both foundational knowledge and hands-on experience with CO₂ systems.

CO₂ refrigeration, which has gained significant traction in ice arenas and supermarket coolers, is now emerging as a groundbreaking technology revolutionizing the way we cool and heat across industries worldwide.

As Americans embrace a more sustainable future, the refrigeration equipment and architecture must continue to evolve

The escalating demand for sustainable, energy-efficient, and environmentally conscious cooling technologies presents a compelling business case for CO₂ refrigeration. And U.S. businesses are taking notice.

In the ongoing battle against climate change, the U.S. supermarket sector is relentlessly pursuing innovative strategies to reduce its carbon footprint and enhance energy efficiency.

CO₂ refrigeration (R-744) was selected to cool four ice rinks at the Winter Olympics, curbing carbon emissions to the tune of 1.2 million planted trees.

The commercial and industrial refrigeration sector is going green. This evolution is largely dictated by corporate environmental, social, and governance efforts; the demand for greater energy efficiency; government regulations; net-zero energy goals; and more.

The proper design, installation, and maintenance of these valves is vital for the safe operation of R-744 refrigeration systems, especially in industrial and commercial applications.

Compiled via interviews with a team of experts, here are the steps one should follow when charging a CO₂ refrigeration system.

As the industry continues to gray and the demand for HVAC services continues to rise, recruiting, training, and retaining young talent is crucial to the trade’s future.
