Commercial Refrigeration Preventive Maintenance

Stay Ahead of System Failures. Protect What Matters Most.

Wright Brothers and Commercial Refrigeration Preventative Maintenance

Refrigeration systems aren’t just another part of your building — they’re part of your business. Whether you’re storing perishable goods, temperature-sensitive products, or regulated medical supplies, even a brief system failure can have serious consequences.



At Wright Brothers Inc., we provide commercial refrigeration maintenance programs designed to prevent costly breakdowns, extend system life, and maintain performance under pressure. Our preventive work goes beyond basic checks — we deliver deep technical inspections, real-time adjustments, and long-view reporting so you can manage your systems proactively, not reactively.

Maintenance Built for Commercial Loads and Continuous Operation

Unlike comfort cooling systems, refrigeration runs 24/7. That means component wear, pressure drift, and control errors accumulate faster — and cause more damage if they go unnoticed.

Our preventive maintenance programs are built around real commercial conditions: heavy usage, fluctuating demand, sensitive inventory, and compliance obligations. We perform structured inspections on low-temp and medium-temp systems, rack-mounted installations, walk-ins, reach-ins, prep units, and more — including their controls, defrost logic, and airflow systems.

Each visit includes:

  • Evaporator coil inspection and cleaning to ensure proper heat exchange and airflow
  • Refrigerant pressure and superheat readings to monitor charge stability and compressor performance
  • Electrical testing on contactors, relays, and overloads to prevent nuisance trips and hard-start failures
  • Compressor amp draw and temperature analysis to detect motor fatigue or imbalance
  • Defrost timer and termination sensor testing (mechanical and adaptive logic)
  • Control system check and alarm verification for KE2, Danfoss, Emerson, or standalone setups
  • Drain line and pan inspections to prevent water overflow and microbial growth
  • Case temperature logging and trend review to spot issues before they trip alarms

Every maintenance visit concludes with a written report detailing work performed, system health, and any recommended repairs or monitoring items.

Tailored Plans, Not One-Size-Fits-All

Different operations have different risks. A foodservice kitchen needs predictable defrost and quick pull-down. A vaccine room needs precise holding temps and data logging compliance. A cold-storage warehouse might need seasonal adjustment based on inventory volume or outdoor heat load.

That’s why we design custom refrigeration maintenance plans for every client. Monthly, quarterly, or seasonal service — we schedule based on your usage profile, regulatory needs, and system type.

And because we track your service history, we can help identify aging components that may not be an issue yet — but will be. This helps our clients forecast capital improvements, align maintenance with budget cycles, and avoid unplanned outages that could put operations or inventory at risk.

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 Preventive Maintenance is a Business Strategy — Not Just a Line Item

Refrigeration systems don’t usually fail all at once — they decline. Heat transfer efficiency drops. Fans slow down. Sensors drift out of calibration. Without early detection, these slow failures become sudden ones — and by then, the damage is done.

With a Wright Brothers maintenance plan in place, you get:

  • Lower service costs over time, by replacing parts before they fail
  • Energy savings through clean coils, accurate controls, and efficient load management
  • Fewer emergency calls, with issues handled proactively
  • Better compliance positioning, with full service documentation and calibration logs
  • Longer equipment life, helping you avoid early capital expenses

Our goal is simple: to protect your systems so you can focus on running your facility — not reacting to failures.
