02 · What we service
Six commercial refrigeration categories.
Walk-In Coolers and Freezers
The big boxes. Restaurant walk-ins typically run R-404A on systems built 2010 to 2020, transitioning to R-448A or R-449A on newer installs. Common failures we see in coastal LA: condenser fan motor seizure (3 to 6 years on coastal restaurants in Santa Monica, Manhattan Beach, Newport Beach due to salt-air dust load), evaporator coil icing from defrost cycle issues, door gasket failure (commercial gaskets see 50 to 200 cycles per day), compressor short-cycling on ambient heat, refrigerant slow leak. EPA 608 required for any sealed system work.
Walk-in coolers run 36 to 40°F. Walk-in freezers run -10 to 0°F. Different evaporator design, different defrost requirements (electric defrost on freezers, off-cycle on coolers). Same general architecture but different repair playbook. See walk-in cooler repair and walk-in freezer repair.
Reach-In Coolers and Freezers
The upright units in commercial kitchens, single, double, triple door. Brands we service constantly: True (T-23, T-49 most common), Turbo Air (M3R series), Traulsen (G Series, R Series), Beverage-Air (HR1, HR2 horizontal reach-ins), Continental, Migali, Victory, Norlake, Avantco, Maxx Cold.
Common failures: condenser fan motor (1,800 to 3,000 RPM motors run 24/7, 4 to 6 year typical service life), evaporator fan motor, door gasket compression at the hinge side first, defrost timer (electromechanical timers on legacy units, defrost boards on modern), thermostat failure, compressor relay and start components. EPA 608 for sealed system work. See reach-in cooler repair and reach-in freezer repair.
Prep Tables (Salad / Sandwich Refrigerated Prep Stations)
Cold rail at top, refrigerated drawers or doors below, cutting surface in front. Most are True (TPP series), Turbo Air (PRT, MST series), Continental (CPP series), Beverage-Air (SP, DP series). Critical for sandwich shops, taquerias, salad concepts. The cold rail temperature spec is 41°F or below per FDA Food Code. Failing prep tables become health code violations fast.
Common failures: cold rail temperature drift (most common, needs evaporator cleaning plus sometimes thermostat adjustment), pan condensation pooling (drain blockage), door gasket compression on the storage section, compressor short-cycling on heavy-load operations. See prep table repair.
Display Cases
Deli cases, bakery cases, beverage merchandisers, open-air refrigerated displays. Brands: Hussmann (most common in LA grocery), Federal Industries, Howard McCray, True (TG series glass-door merchandisers), Hoshizaki commercial display, Beverage-Air. Glass door defrost issues, internal humidity, lighting harness failures, condenser fan motors.
We service both self-contained units (compressor inside the case) and remote-condensed displays where the condenser is on the roof or in a back room. Self-contained: any LA-area appliance shop with EPA 608 can service. Remote-condensed: this is where most shops decline because they don't understand the line set work. We service these. See display case repair.
Undercounter Refrigerators and Drawers
Smaller commercial reach-ins designed to fit under prep counters. Common in bars (back-bar bottle storage), small kitchens, mobile units. Perlick (HP15, HP24, independent Wisconsin manufacturer since 1917), True (TUC series), Hoshizaki commercial, Krowne, Glastender. Service profile similar to reach-ins but more compact. EPA 608 for sealed system. See undercounter refrigerator repair.
Wine Cellar Cooling (Restaurant / Hospitality)
Restaurant wine cellars and luxury hospitality wine displays use specialized cooling: typically Wine Guardian, CellarPro, KoolR for cellar systems, plus integrated wine refrigeration in dining rooms. Different temperature targets (55°F for red, 50°F for white, varying humidity 50 to 70%). EPA 608 for sealed system work.
