Commercial Refrigeration Retrofit

Modern Performance. Lower Operating Costs. Fewer Headaches.

Wright Brothers and Commercial Refrigeration Retrofit

Aging refrigeration systems don’t always need full replacement — but they do need attention. As equipment ages, efficiency drops, maintenance costs increase, and older refrigerants or control systems may fall out of spec. If you're starting to see inconsistent temperatures, escalating energy usage, or repeated component failures, it's time to consider a retrofit.



Wright Brothers Inc. designs and implements commercial refrigeration retrofit solutions tailored to your facility’s layout, operational needs, and budget. We work with restaurants, grocery operations, healthcare labs, food production facilities, and cold storage environments to modernize systems and restore reliability without the disruption of a complete rebuild.


Retrofit vs. Replace: What Makes Sense for Your Operation

A retrofit doesn’t mean starting from scratch. It means making the right upgrades to keep your system operating safely, efficiently, and in compliance — without tearing everything out.

Our refrigeration retrofit services may include:

  • Compressor upgrades to modern scroll or semi-hermetic platforms for better energy performance
  • Control system conversions to KE2 Therm, Emerson E2, Carel, or Danfoss for tighter temp control and visibility
  • Refrigerant conversions, to meet environmental regulations without loss of performance
  • Evaporator or condensing unit replacements while preserving line sets and rack infrastructure
  • Valve and TXV retrofits to reduce superheat variability and optimize load response
  • Integration of remote monitoring and alarm systems to support compliance and reduce onsite response requirements

We tailor every retrofit to your environment — whether you're managing a busy production kitchen, a 10,000-square-foot cooler, or a climate-controlled lab space with narrow tolerances.

Retrofit Planning Built Around Your Operation

Our team begins with a full on-site system assessment. We review your equipment history, temperature stability, service records, and future operational needs. From there, we scope a retrofit strategy that prioritizes:

  • Efficiency gains that reduce electrical consumption and compressor runtime
  • Serviceability improvements that reduce long-term labor costs and simplify maintenance
  • Regulatory compliance, especially for food safety, health inspections, or medical-grade environments
  • Minimized disruption, with work scheduled during low-traffic or off-peak windows

Wherever possible, we phase upgrades to reduce downtime and ensure you’re never without cooling when it matters most. Our team handles everything from equipment sourcing and vendor coordination to post-retrofit performance validation.

OUR Process

Every service begins with a site assessment — not just to scope the work, but to understand the environment it’s happening in. Access. Downtime windows. Crane or rigging requirements. Electrical capacity. Control integrations. All of it.

We coordinate seamlessly with electrical teams, building controls vendors, and rigging companies to make sure a system replacement doesn’t stall out waiting for a missing part or unplanned disconnect.

Crews are sized appropriately for the job, from solo diagnostics to multi-technician installations. Our lead techs carry the certifications and the experience to not only execute but troubleshoot mid-job, without calling in backup.

Documentation follows every service, and if a follow-up is required, it’s already scheduled before we leave.

Wayfield Foods – Refrigeration Retrofit (2023)

Performed a full refrigeration retrofit at Wayfield Foods Store #19 in Lithia Springs, GA, upgrading aging case systems for improved temperature control and energy efficiency. The project included retrofitting existing display lines with updated coils and TXV configurations, converting refrigerants to EPA-compliant standards, and upgrading control platforms to digital logic. Work was phased during off-hours to maintain store operations, with system pressure testing, line rebalancing, and full commissioning confirming reduced cycle frequency and improved pull-down performance across the floor.

Kroger – Refrigeration Service Call (2025)

Responded to an emergency service call at a Kroger in Stockbridge, GA to address a shattered glass end panel on a Hussmann IM-04-C8-R multideck island-style refrigerated dairy case. Sourced a matched replacement panel and performed a same-day repair, securing the new component with precision alignment, bolting, and silicone sealing to restore thermal insulation and safety without disrupting product display or requiring full system shutdown.

USDA – Refrigeration Preventive Maintenance (2025)

Completed quarterly preventive maintenance for USDA’s Griffin, GA facility, focusing on walk-in cooler and freezer systems critical to temperature-sensitive storage. Service included full evaporator inspection, pressure and temperature readings, defrost cycle verification, suction line insulation review, and drain line clearing. Refrigerant levels were benchmarked against prior readings to confirm system integrity, and full documentation was provided to support compliance and audit readiness.

Why Wright Brothers Handles Retrofit Work Differently

A successful retrofit is about far more than installing new parts — it’s about understanding how new components interact with old infrastructure, how downtime impacts your workflow, and how to make sure performance improves over the long term, not just at install.

We bring:

  • Decades of refrigeration-specific retrofit experience across industries and system types
  • Field technicians with deep diagnostic and commissioning training, not just installers
  • Strong vendor relationships with major brands and controls providers
  • Start-to-finish project management, from scoping and sourcing to system validation and service documentation

Our goal is not just to complete the job — it’s to improve your system’s reliability, compliance position, and total cost of ownership for years to come.
