CO₂ refrigeration retrofits and upgrades for Metro Atlanta cold facilities
Low-temp CO₂ / natural-refrigerant retrofits, upgrades, commissioning, and service for cold storage and food manufacturing — not plant chillers or comfort cooling.
CO₂ is a low-temp refrigeration product family — not a chiller plant. Willis Mechanical supports CO₂ / natural-refrigerant systems for Metro Atlanta cold storage and food manufacturing with retrofit, upgrade, commissioning, and service depth from CO₂-capable technicians.
Service area: refrigeration service, repairs and retrofits across Metro Atlanta and north Georgia, from Adairsville, Rome and Cartersville to Gainesville and Athens, and beyond for larger refrigeration clients.
This page is not for plant chillers or comfort cooling. If you need chilled-water plants, process loops, or building comfort cooling, see ChillersBoilers. For broader low-temp cold storage and food manufacturing refrigeration, see Refrigeration.
What CO₂ work covers
- CO₂ (R-744) / natural-refrigerant systems for cold rooms, freezers, and low-temp process spaces
- Retrofits, conversions, and capacity upgrades on CO₂ racks
- Commissioning, start-up, and ongoing service with CO₂-capable technicians
- Diagnostics and emergency response when a CO₂ rack threatens product or production
- Clear separation from HFC-only generic calls and from plant chillers
How we work in occupied cold facilities
- Plan rack and retrofit work around product and inventory uptime
- Phased renovations and special projects in live coolers and freezers wherever the application allows
- One accountable Metro Atlanta team from the service call through commissioning
- Not a drop-ship equipment sale — maintenance and project labor behind the work
Where it applies
- Cold storage and distribution facilities running or evaluating CO₂
- Food manufacturing and beverage plants with low-temp CO₂ systems
- Owner-operated Metro Atlanta sites that need natural-refrigerant depth without juggling vendors
- Facilities leaders treating CO₂ maintenance and retrofits as high-value work, not a commodity PM
Renovations, retrofits & special projects
CO₂ work here is renovations, retrofits, upgrades, and special projects in facilities that already run cold — not ground-up construction. Request Service: call (678) 966-0094, request service, or start a project.
CO₂ refrigeration FAQ
Is CO₂ refrigeration the same as chillers or comfort cooling?
No. This page is natural-refrigerant / low-temp CO₂ for cold storage and food manufacturing. Plant chillers for process or comfort cooling are a different product on ChillersBoilers.
Does Willis Mechanical handle CO₂ refrigeration retrofits in Metro Atlanta?
Yes — CO₂-capable technicians for retrofits, upgrades, commissioning, and service, planned around uptime in occupied cold facilities rather than selling equipment alone.
Can a CO₂ retrofit keep cold spaces online?
That is how we scope the work: phased renovations, retrofits, and special projects around live product loads whenever the application allows.
How is this different from general refrigeration?
General Refrigeration covers low-temp cold storage and food manufacturing broadly. This page goes deeper on CO₂ / natural-refrigerant retrofits and CO₂-trained service.
