Cold storage companies hiring right now need techs who can keep product at temp with zero downtime. Here's who's hiring, what they pay, and how to get in fast.
These operators consistently hire industrial refrigeration techs across the U.S. They run ammonia and CO2 systems, large warehouses, and 24/7 operations.
One of the largest cold storage networks in North America. Heavy on ammonia systems, with constant demand for IIAR-trained techs.
Publicly traded operator with automated warehouses and legacy plants. Hiring service techs, operators, and maintenance supervisors.
Family-owned, stable operations. Known for long-tenured techs and steady overtime availability.
High-density automated warehouses. More PLC exposure than most competitors.
Strong presence in northern states. Cross-border opportunities for experienced ammonia techs.
Tyson Foods, Cargill, and Smithfield Foods run their own cold storage alongside processing plants. Expect larger systems, more compliance, and higher safety standards than a standalone warehouse. See how refrigeration jobs at food manufacturing plants differ from pure cold storage.
Cold storage companies are competing hard on wages. The labor shortage for ammonia techs is real.
Two or more of these puts you at the top of the pay band. A tech with RETA certification typically earns 10% to 18% more than non-certified peers.
Hiring is not evenly spread. It clusters around distribution hubs and food production regions: Texas, California, Iowa, Georgia, and Pennsylvania.
Iowa alone has over 150 cold storage and food processing facilities within a 100-mile radius of Des Moines.
Cold storage operators in these areas rarely stay fully staffed.
Generic HVAC certs do not move the needle here. These employers want proof you can work safely on industrial systems.
Non-negotiable. If you don't have it, start here.
The credential that separates industrial techs from commercial techs on paper.
Plant-site safety baseline. Some operators will not let you on the floor without it.
IIAR ammonia training certificates, hazmat awareness, and PLC troubleshooting experience. Each one widens the pay band.
Cold storage is not light commercial HVAC. You are dealing with -10°F to -20°F freezer environments, 24/7 operations with no shutdowns, ammonia systems under strict safety protocols, and large compressors, evaporators, and vessel systems.
You will be on-call. You will work nights early in your career. In return, you get steady hours, overtime, and job security. Understand the PSM compliance and safety requirements before your first shift, not after.
Most techs who get hired do steps 2 and 5. That alone puts you ahead of half the applicants.
Expect direct, practical questions. They are not testing theory. They are testing whether you can handle real plant conditions.

Lineage Logistics, Americold, United States Cold Storage, Preferred Freezer Services, and VersaCold hire consistently across the U.S. Integrated operators including Tyson Foods, Cargill, and Smithfield Foods also run their own cold storage alongside processing plants.
A refrigeration technician typically earns $30 to $42 per hour, or $65,000 to $90,000 annually. Senior ammonia techs earn $40 to $55 per hour, or $85,000 to $115,000. Maintenance supervisors are salaried at $95,000 to $130,000.
EPA Section 608 Universal, RETA CIRO or CARO, and OSHA 10 or 30 are the must-haves. IIAR ammonia training certificates, hazmat awareness, and PLC troubleshooting experience are strong additions.
Not always. Highlight any ammonia exposure, even limited. Many operators hire techs with commercial refrigeration backgrounds and train them on ammonia, especially if you are upfront about shift flexibility.
Hiring clusters around distribution hubs and food production regions: Texas, California, Iowa, Georgia, and Pennsylvania. Iowa alone has over 150 cold storage and food processing facilities within a 100-mile radius of Des Moines.
Cold storage operators are short on skilled techs. That gap is your opportunity. If you can handle industrial systems and show up consistently, you will have multiple offers.
