Kroger will spend $100 million to reduce refrigerant leaks and replace hundreds of systems under a proposed DOJ settlement over alleged Clean Air Act violations.

As refrigerants evolve, compressor lubricants must keep pace. The wrong oil-refrigerant combination can reduce efficiency, damage compressors, and shorten system life.

EPA finalized revisions to the TT Rule, easing several refrigerant deadlines and expanding compliance flexibility for several HVACR sectors. 

CO₂ refrigeration systems demand careful attention to detail. Following a few key best practices can help technicians avoid common mistakes and ensure a smooth startup. 

Heating, Air-conditioning & Refrigeration Distributors International (HARDI) and the Plumbing-Heating-Cooling Contractors–National Association (PHCC) are urging the U.S. Supreme Court not to take up a case challenging the Environmental Protection Agency's rules on bulk HFC allocations.

Experts examine EPA rulemaking, the A2L refrigerant transition, and state-level initiatives that are shaping the future of HVACR regulation. 

AI-driven data center growth is reshaping cooling strategies, driving adoption of lower-GWP refrigerants as manufacturers develop solutions that balance efficiency, sustainability, and reliability. 

The shift to low-GWP refrigerants is raising the stakes on vendor oversight, making compliance documentation more important than ever for HVACR contractors.

The analog gauge sets are built for HVACR system diagnostics, refrigerant recovery, pressure testing, and charging. 

More organizations have piled on, asking the Supreme Court to take a look at a case that could limit how much power Congress can delegate to the EPA.
