Commercial Refrigeration Oklahoma City repairs commercial refrigerators across Oklahoma City: glass-door and open merchandisers, back-bar and bottle coolers, deli, bakery, and floral cases, and solid-door kitchen uprights. Whether the unit is self-contained or fed from a remote condensing unit, the failure list is consistent, a dirty or failing condenser, a fan motor, a control or thermostat, a door or gasket, or a sealed-system charge problem. The first visit isolates it and fixes what is on the truck.
What we do on the first visit
The technician checks the condenser and its fan, the evaporator fan and coil, the temperature control or electronic controller, and the door and gaskets, then reads pressures if the symptoms point to the sealed system. Merchandisers live in warm retail spaces with constant door traffic, so condenser cleaning, a fan motor, a controller, or gasket replacement resolves most calls. Compressors and condensers are quoted in writing.
Merchandisers work hardest exactly when you need them
A glass-door merchandiser in a convenience store or grab-and-go sits in 74–78 °F conditioned air with the doors opening hundreds of times a shift, and it peaks in summer when store traffic and ambient heat both climb. That duty cycle is brutal on the condenser fan and the compressor start components. When a merchandiser starts losing the bottom shelf first, it is usually airflow: a failing evaporator fan, a frosted coil from a defrost or gasket issue, or a condenser that cannot keep up. The technician verifies airflow top to bottom before touching the charge.
Electronic controllers and sensor drift
Modern cases use electronic controllers with probes for box temperature, coil temperature, and defrost termination. A probe that has drifted or an intermittent connector makes the case behave erratically: short-cycling, over-defrosting, or never defrosting. The technician reads the controller's live sensor values against a calibrated thermometer, checks the wiring, and replaces the specific probe or controller rather than swapping parts by guess. Getting the control right also protects product and keeps you inside health-code holding temperatures.
Insurance and payment
Repairs are quoted flat with the diagnostic applied to the work. For a merchandiser or case failure that spoils stock, Commercial Refrigeration Oklahoma City provides an itemized invoice, the written diagnosis, and temperature documentation for an equipment-breakdown or spoilage claim.
What's included
- Flat-rate diagnostic quoted before the visit and applied to the repair
- Condenser and evaporator inspection, coil cleaning where airflow is the fault
- Electronic controller and probe diagnosis against a calibrated reference
- Evaporator and condenser fan motor replacement from stock
- Compressor start-circuit test and stocked start-component replacement
- Door, hinge, gasket, sweep, and anti-sweat heater service
- Drain line clearing and case interior water removal
- Written price and schedule for compressor or condenser replacement
Symptoms we get called for
- Merchandiser not holding product temperature on the bottom shelf
- Compressor cycling rapidly or humming and tripping
- Ice on the evaporator cover, warm air from the vents
- Condensation running down the inside glass or pooling in the base
- Loud rattle or buzz from the condensing section
- Lighting out, door not closing, or torn gaskets losing cold
