Freezers and Coolers

The shift to lower-GWP refrigerants in commercial refrigeration is accelerating, with food retailers adopting diverse options including R-290, A2L systems, and CO₂ solutions for various store formats.  

CO₂ refrigeration avoids regulatory and environmental risks, while delivering long asset life and lower total cost of ownership. 

Food retailers are transitioning from HFCs to CO₂ or A2L refrigerants, but the right choice depends on climate, codes, cost, safety, and skilled labor availability. 

The AIM Act and state rules have made refrigerant management mission critical, with tighter leak rules, faster timelines, and steep federal and state fines for noncompliance.

EPA’s proposed rule may offer short-term flexibility, but industry leaders warn it could trigger HFC shortages and stranded assets. 

Thanks to a generous grant, two grocers in the Bronx were able to replace their HFC refrigeration systems with ultra-low GWP R-290 cases. 

Troubleshooting and replacing a liquid line solenoid is generally not a difficult task – if technicians understand their design and how they operate. 

Solving frost or ice issues with a walk-in freezer is generally not difficult but will require a thorough inspection to find the root cause of the issue.
