When a commercial walk-in cooler, restaurant freezer, or food prep line loses temperature, thousands of dollars in perishable inventory and health code compliance are at stake. ARSF provides immediate 24/7 emergency dispatch, EPA-certified diagnostics, and master component repairs.
On-call round-the-clock emergency dispatch for restaurant and grocery cold storage failures.
Certified in R404A, R448A, R449A, R290 (propane), and R134a recovery and charging.
Carrying commercial contactors, Dixell/Carel controllers, defrost timers, and TXV valves.
All commercial component repairs backed by our guaranteed 90-day parts and labor warranty.
From restaurant walk-in boxes and supermarket reach-in cases to industrial blast chillers and commercial fryers, our certified technicians service all commercial equipment.
Custom walk-in cold rooms and modular boxes from Norlake, Kolpak, and Bally maintaining 35°F to 38°F holding temperatures for restaurants, breweries, and florists.
Heavy commercial low-temp walk-in freezers maintaining -10°F to 0°F storage. Resolving iced coils, defrost timer failures, and compressor short-cycling.
1, 2, and 3-door solid stainless reach-in refrigerators, sandwich prep tables, and chef bases from True, Turbo Air, Traulsen, and Beverage-Air.
High-output 300 to 1,500 lb/day commercial ice makers from Hoshizaki, Manitowoc, and Scotsman for bars, seafood markets, and hospitality.
Glass-door reach-in merchandisers, open-air dairy cases, and underbar back bar coolers from Perlick and True requiring uniform product temperatures.
Integrated kitchen hot-side service specializing in Pitco commercial deep fryers, Vulcan ranges, and Hobart commercial convection ovens.
Here are the most frequent breakdown symptoms diagnosed and corrected by our commercial technicians across restaurant and food service kitchens.
Refrigerant leak in evaporator flare joints, restricted liquid-line filter drier, or locked compressor rotor threatening food spoilage and health citations.
Defective defrost clock/timer, burned-out electric defrost calrod element, failed defrost termination bimetal, or seized evaporator fan motor.
Severely clogged condenser coils causing high head pressure cutouts, failing run capacitor, or pitted magnetic motor contactor contacts.
Biological slime or grease clogging the condensate drain line, unheated drain line freezing in sub-zero freezers, or cracked drain trough pan.
Failed NTC/PTC temperature sensor probe, communication bus failure, or low-voltage power supply drop causing erratic temperature regulation.
Weak millivolt thermopile output (< 450mV), clogged pilot burner orifice, defective safety magnet valve, or tripped high-limit switch.
Digital 4-valve refrigeration manifolds, micron vacuum gauges & electronic leak sniffers.
Commercial food preservation tolerates zero guesswork. Our EPA-certified refrigeration specialists use industrial diagnostic instrumentation to verify proper thermodynamic cycle operation.
We calculate real-time superheat at the evaporator outlet and subcooling at the condenser exit using digital temperature clamps and manifold pressure transducers.
Testing lines under 350 PSI dry nitrogen pressure and scanning with heated diode refrigerant sniffers capable of detecting micro-leaks down to 0.1 oz/year.
Megohmmeter insulation resistance testing on compressor motor windings, amp draw verification against RLA/LRA ratings, and phase voltage balance checks.
Our commercial service vehicles carry genuine OEM factory components for all leading food service refrigeration, ice maker, and cooking equipment manufacturers:
Factory-certified service for True reach-ins, prep tables, glass merchandisers, and bar back refrigeration suites.
Commercial reach-in refrigerators, heated cabinets, and roll-in blast chillers with Smart Control digital systems.
Digital smart defrost controls, self-cleaning condenser maintenance, and hydrocarbon R290 refrigerant system rebuilds.
Crescent cube evaporators, harvest valve diagnostics, water pumps, and high-efficiency commercial reach-in units.
From your initial emergency call to safe holding temperature verification, here is how our technicians protect your business operations.
Call our commercial dispatch line at (415) 991-1573. We prioritize refrigeration emergencies with 1 to 2-hour arrival windows.
We evaluate compressor amperage, test superheat/subcooling, check defrost controls, and scan for refrigerant leaks.
With your approval, we install factory OEM compressors, TXV valves, fan motors, or controllers directly from our stocked service vans.
We monitor system pull-down until safe food holding temperatures are achieved, providing you with full written warranty documentation.
