Commercial Refrigerator Repair in Glendale, CA
Walk-in coolers, reach-in units, prep tables, and glass-door merchandisers back in the safe temperature range fast. Licensed technicians, same-day service, and repairs completed on the first visit whenever parts allow.
ABOUT OUR COMMERCIAL REFRIGERATOR REPAIR SERVICE
A refrigerator that drifts above 41°F threatens your inventory and your health inspection at the same time. Dairy, cooked proteins, and prepped items enter the temperature danger zone within a couple of hours, and one failing unit can cost you a full day of prep. That is why commercial refrigeration calls receive priority dispatch: most are scheduled same-day, and we arrive ready to complete the repair on the first visit.
Our technicians are licensed by California BHGS (#49152) and EPA Section 608 certified, which is required for any legal work on sealed refrigerant systems. We service every configuration a working kitchen runs: walk-in coolers, reach-in refrigerators, sandwich and pizza prep tables, undercounter and back bar units, glass-door merchandisers, and refrigerated display cases. Brands we cover include True, Turbo Air, Beverage Air, Atosa, Avantco, Continental, Delfield, Traulsen, and Everest.
Diagnosis starts with the system, not the symptom. Superheat and subcooling readings, condenser and evaporator temperature splits, compressor amp draw, and controller settings tell us whether the fault is refrigerant-, airflow-, electrical-, or control-related. We use OEM parts as standard, with commercial-grade alternatives available when timing is critical and approved by you. Every repair is backed by a 60-day warranty.

Common Commercial Refrigerator Problems
We Fix
Commercial refrigerators work in hot kitchens, with doors opening hundreds of times per shift and warm product loaded straight into them. Below are the failures we diagnose and repair most often for Glendale restaurants, markets, cafes, and healthcare facilities.
1. Unit Will Not Hold 41°F or Below
The failure that puts you out of compliance. Products held above 41°F must be discarded, so this is our top priority call. Causes range from low refrigerant charge and a restricted metering device to a dirty condenser or a failing compressor. Control faults produce the same symptom in reverse: a drifting temperature probe or a failed board can show 38°F on the display while the box sits at 50°F or leave the compressor waiting for a call that never comes. We verify actual product temperature against the display before anything else, then test sensors against calibrated instruments.
2. Condenser Coil Blockage from Kitchen Grease
Airborne grease is the single biggest killer of commercial refrigeration in a restaurant. Grease combines with dust and forms an insulating layer on the condenser, so the system cannot reject heat. Head pressure climbs, run time never ends, and the compressor eventually fails. We clean and comb coils, check fan operation, and show you the condition of the coil so you can set a realistic cleaning interval.
3. Compressor Short Cycling or Running Nonstop
A compressor that starts and stops every few minutes is usually being tripped by a pressure control, a bad start component, an overload, or low charge. A compressor that never shuts off points to a heat rejection or load problem: blocked condenser, warm ambient air, doors left open, or a unit undersized for what it is being asked to do. Both patterns shorten compressor life dramatically, so we identify which one you have before parts are ordered.
4. Refrigerant Leaks and Low Charge
Vibration, corrosion, and flare fittings that loosen over time create leaks in evaporator coils, line sets, and Schrader valves. Symptoms include gradual temperature rise, ice forming on the suction line, and a compressor that runs constantly without pulling the box down. Under EPA Section 608, leaks must be repaired rather than simply topped off, so we locate the leak, repair it, evacuate the system, and recharge to the manufacturer specification.
5. Evaporator Fan Failures and Warm Spots
Evaporator fans push cold air across the box. When a fan motor seizes or a blade is damaged, cold air stalls at the coil, and you get stratification: safe temperatures near the sensor and unsafe temperatures on the shelves where product actually sits. Failed fans also allow the coil to ice over, which restricts airflow further. We test motor amp draw, replace failed motors and blades, and confirm even temperatures across every shelf.
6. Door Gaskets, Hinges, and Anti-Sweat Heaters
Commercial door seals wear out far faster than residential ones because of constant use and rough handling. A torn or hardened gasket lets warm humid air infiltrate the cabinet, which drives up run time, causes coil icing, and produces condensation inside the box. On glass-door merchandisers, failed anti-sweat heaters cause fogged doors that hide your product. We replace gaskets to exact manufacturer specifications, realign sagging doors, repair self-closing hinges and cam lifts, and test door heater circuits.
7. Condensate Drain Clogs and Water on the Floor
Every refrigerator produces condensate that has to drain. In commercial kitchens, grease, food debris, and biofilm block drain lines and pans, so water backs up inside the cabinet, freezes on the coil, or spills onto the floor and creates a slip hazard. Glendale's hard water accelerates mineral scale in drain lines and evaporation pans. We clear the line, clean the pan, verify the trap, and correct pitch issues that let water sit.
8. Prep Table and Walk-In Cooler Specific Issues
Prep tables are the most cited units in an inspection because the top rail runs at the edge of the safe range by design: pans above the airflow line, a cracked rail gasket, or a missing night lid will push rail temperature over 41°F while the base cabinet reads perfectly.
Walk-ins bring their own list: failing door closers, drooping strip curtains, damaged sweep gaskets, rooftop condensing units baking in Glendale heat, and defrost timers set for a freezer load rather than a cooler. We diagnose the rail and the cabinet as separate loads and the walk-in evaporator and condensing unit as one system.
