Commercial Refrigeration Services

Maintenance and Repair for Coolers, Freezers, Chillers, Ice Machines & More

What We Service

Walk-In Coolers and Freezers

Reliable temperature control begins here. We diagnose and repair compressors, condensers, evaporators, fan motors, control boards, sensors, defrost systems, door heaters, and gaskets. If frost, icing, or drifting temperatures are creeping in, we restore stable performance and food-safe conditions.

Commercial Freezers

Critical inventory requires reliable freezing. We service upright commercial freezers, chest models, and large multi-door systems. Our technicians repair defrost components, replace worn door gaskets, fix thermostat and control failures, resolve refrigerant leaks, and restore consistent sub-zero storage. Whether it is ice buildup, noisy operation, or fluctuating temperatures, we return freezers to dependable performance.

Reach-In Refrigerators and Freezers

Upright, undercounter, and back-bar units require tight airflow, clean coils, and healthy door seals. We correct short cycling, warm spots, water leaks, noisy fans, and erratic thermostats, then calibrate controls for consistent holding temps.

Display Cases and Merchandisers

Open-air and glass-front cases demand peak efficiency to keep product inviting and safe. We service airflow baffles, curtain assemblies, LED drivers, evaporator drainage, and case controllers, and ensure defrost and lighting schedules match your operating hours.

Prep Tables and Line Coolers

Production lines thrive on predictable cooling. We clean and sanitize coils, replace door and lid gaskets, level and drain pans, set fan speeds, and dial in set points for safe, ready-to-serve ingredients.

Beverage and Draft Cooling

From glycol chillers to bottle coolers, we maintain temperature stability across soda fountains, kegerators, and back-bar refrigeration. Expect crisp pours, steady carbonation, and reliable service during rush periods.

Ice Machines

Quality ice starts with clean water and a spotless machine. We descale and sanitize, rebuild water inlet valves, repair pumps and harvest cycles, resolve bin control faults, and set up filtration programs that protect equipment and product quality.

Commercial and Sealed System Services

  • Comprehensive diagnostics using gauges, electronic leak detectors, and data logging
  • Component-level repairs for compressors, condensers, evaporators, TXVs, EEVs, fan assemblies, contactors, relays, and control boards

Customer Satisfaction

Total customer satisfaction is at the core of our business and every job we perform.

Preventive Maintenance Programs

  • Scheduled coil cleaning for condensers and evaporators
  • Door gasket inspection and replacement for tight seals and lower energy use
  • Drain line clearing and pan treatment to prevent clogs and odors
  • Defrost system inspection and calibration to stop icing and temperature swings
  • Electrical checks for connections, amperage, and contact wear
  • Performance reports that track temperature stability and energy trends over time

24/7 Emergency Service

Equipment failures do not wait for business hours. Our rapid response team isolates faults quickly, stabilizes product temperatures, and completes permanent repairs with minimal downtime. You get clear communication, documented findings, and recommendations that prevent repeat issues.

Compliance and Food Safety

We help you stay audit-ready with calibrated sensors, verified holding temperatures, proper labeling of refrigerants and components, and maintenance logs that satisfy health inspections and corporate standards. Technicians follow EPA refrigerant handling rules and manufacturer service procedures.

Energy and Controls Optimization

  • Set point and differential tuning for stable product temperatures
  • Floating suction and head pressure strategies to reduce compressor workload
  • Case controller programming aligned with open and close schedules
  • Night covers, door heater strategies, and fan cycling for additional savings
  • Data monitoring options that alert your team before small deviations become product loss

Leak Detection and Refrigerant Management

Refrigerant leaks waste energy and reduce cooling capacity. We perform pressure tests, isolate circuits, repair or replace faulty components, and document recovery and charging. Ongoing inspections protect efficiency and extend equipment life.
