Commercial Refrigeration Repair · Bay Area

What we fix

We keep working kitchens and bars cold across the Tri-Valley and greater East Bay: back-bar fridges, glycol-chilled beer trunks, walk-ins, reach-ins, prep tables, undercounter beverage centers and refrigerated display cases. The brands a real kitchen runs on, Perlick, Atosa, Hoshizaki, True, Turbo Air, Beverage-Air, Continental, Traulsen. The diagnostic is $75, waived if you have us do the repair, and you get parts and labor in writing before anybody turns a wrench.

Most of these calls follow a few patterns. A gasket has stretched. A coil is packed with grease and dust. A condensate line is plugged. Or the glycol mix has drifted off spec. We stock the usual gaskets, condenser-fan and evap-fan motors, and an inline tool for clearing condensate drains right on the truck. Sealed-system work stays in house with full recovery, evacuation and weigh-in. Our EPA #1279674151528 (Section 608) covers refrigerant handling, and we’re HC(A3) / R290 hydrocarbon trained through Mainstream Engineering, which is what most current Atosa units run. That’s usually the reason your last tech said he “couldn’t get parts.”

After-hours line for bar and restaurant work is the same number: (925) 999-4095. A bar emergency at 9pm Friday isn’t going to wait until Monday.

What the usual failures run

Symptom	Typical fix	Parts + labor	Timeline
Box quits cooling	Reach-in compressor replacement	From $500 labor plus materials and the compressor	Diagnosed first, quoted in writing
Temp drifts, controls misread	Controller or thermostat swap	$250 to $350 plus the part	Usually one visit
Compressor never shuts off, power bill climbing	Worn door gaskets, caught on a PM visit	PM from $200 per unit	Quarterly schedule

Real symptoms, real fixes

Perlick back-bar, beer pouring warm. Either the glycol trunk insulation soaked up condensate or the glycol concentration drifted. We check the percentage with a refractometer, flush and refill if it’s off, and re-insulate the run between chiller and tower. One visit handles most of these.

Back-bar fridge icing up after the rush. Bartenders prop the door during service, the gasket stretches, and the evaporator ices the second things slow down. Gasket swap takes under half an hour, and we carry the common Perlick gaskets.

Atosa prep table, water pooling on the floor. Condensate drain clogged with grease and food debris. We pull the line, blow it clear, and fit an inline screen if the layout allows. We note the clean interval so you know when it’s due again.

Hoshizaki sushi case holding warm. On the older platforms the discharge-airflow thermistor drifts and the case sits six to eight degrees over setpoint. We keep the calibrated thermistor stocked and confirm the hold across a full cycle before we leave.

Walk-in evaporator iced over. Defrost timer drift or a dead termination thermostat. We reset the cycle, run the hot-gas or electric defrost through completely, and write the changes inside the panel.

A sealed-system repair is the priciest job on a commercial box, so we’ll tell you straight whether it’s worth fixing or replacing before we start. Quarterly preventive-maintenance visits, coil cleaning, glycol testing, drain clearing and gasket checks, add a couple years to most Atosa units and keep Perlick draft pouring at setpoint.

We’re a service line of ADRIUM Service Solutions (CSLB #1136642, BBB A+). If you also run HVAC or espresso equipment, our sister shops Bay Area HVAC Service (bayareahvacservice.com) and Bay Area Refrigeration Service (bayarearefrigerationservice.com) cover those. We service Perlick, Atosa, Hoshizaki, True, Turbo Air and the rest as an independent shop, no factory-authorization claims, just honest work and a written quote up front.
