Why would a Moraga walk-in struggle more in winter than in summer?

Because cold air outside can drop the condensing unit's pressure too far. Without a working low-ambient control, refrigerant flow to the evaporator falls and the box cools poorly. We test those controls and fix the one that failed. Charge work falls under ADRIUM's EPA 608 Universal certification.

Can you work around a school kitchen's schedule?

Yes. We can book the visit before service or once the kitchen has closed for the day, and the written quote tells you how long the unit will be out of use.

Do leaves really cause refrigeration problems?

They do on an outdoor condensing unit. Leaves block the coil, the unit sheds less heat, and pressure and run time go up. A cleaning each fall and a guard over the fan opening keep it clear.

Commercial Refrigeration Repair in Moraga

Commercial Refrigeration Repair for Moraga kitchens.

Moraga is mostly residential, the quiet corner of Lamorinda in 94556, and its commercial refrigeration is in the places every town has: restaurant and cafe kitchens, school kitchens, club kitchens. The town sits in a canyon behind the Oakland hills, cooler in summer than Walnut Creek or Concord, and winters under the tree canopy run cool and damp.

Cool weather creates a problem hot towns rarely think about. An outdoor condensing unit in cold air can run its head pressure too low, starving the evaporator and frosting the coil. Units built for that have a fan-cycling control or a head pressure valve, and when one fails the box struggles on a cold morning, not a hot afternoon. Leaves and needles from the canopy also collect in the coil. The $99 diagnostic is credited toward the repair, and you approve a written quote before we start.

Common repairs we handle.

Walk-in cooling poorly on cold mornings. Low outdoor temperatures drop head pressure, and without working low-ambient controls the evaporator runs starved. We test the fan-cycling switch or head pressure valve, check the charge and watch the system through a cool start.
Condensing unit coil packed with leaves and needles. Tree litter falls into the fan opening and mats against the coil through the damp months. We clear the housing, wash the coil, check the fan blade for damage and suggest a guard if the unit sits under trees.
School kitchen milk cooler not holding temperature. Milk coolers are opened constantly during service and sit idle over breaks. We check the thermostat, the gasket and the condenser, and clear the drain, which can dry out and clog over a long break.
Compressor cycling wrong on a failed thermostat. A thermostat with a stuck contact or a drifted sensor runs the compressor too long or cuts it out early. We test the control against a probe, replace it if needed and set the cut-in and cut-out for the product in the box.
