Commercial equipment is judged on one thing: whether the business lost trade. That makes scheduling as much a part of the job as the repair, and it makes prevention worth far more than it is on domestic equipment.
Failures here are maintenance, not bad luck
On commercial refrigeration the recurring faults are almost always maintenance-driven rather than defects. Four things account for most of what we are called to:
Fouled condensers. Grease-laden kitchen air coats a condenser coil far faster than domestic dust ever does. A fouled condenser cannot reject heat, so the compressor runs continuously to compensate and fails from overwork long before it would have worn out. A compressor is the expensive end. Condenser cleaning is not.
Worn door gaskets. A reach-in with a torn gasket runs continuously and still drifts above safe holding temperature. It is a cheap part doing an expensive amount of damage, and it is visible from across the kitchen if anyone looks.
Untreated water on ice equipment. Chicago's lake supply scales an evaporator plate steadily. Descaling and filtration on a schedule cost a fraction of a plate, and an air-cooled machine in a hot back-of-house space loses capacity long before it faults outright.
Blocked drains. On refrigeration, on ice machines, on dish machines. They are all the same story: a slow problem nobody notices until it is a fast one.
If the same fault keeps coming back, it is nearly always one of those four rather than a defect. Our report names which of the four it is, so the kitchen fixes the cause once instead of buying the same part every few months.
Scheduling around service
Arriving mid-shift helps nobody. Where the kitchen's routine allows it, we schedule around service — which for most restaurants means before opening, and for a laundromat means early or late depending on its traffic.
We are also plain about it when a fault genuinely cannot wait for a quieter slot. A walk-in losing temperature is not a problem that keeps until Tuesday, and pretending otherwise would be dishonest.
A restaurant that has lost its cold holding or its ice has effectively stopped trading, so those calls move ahead of household appointments already on the schedule.
The documentation side
In a licensed kitchen, how cold the reach-in holds is something a health inspector can ask to see, so the repair record needs to show it.
We record holding temperatures before and after the work, note final rinse temperature on dish machines, and leave a written account of what was found and what was corrected — in a form a manager or an inspector can file. The record should exist before anyone asks for it.
Residential badges doing commercial work
This comes up constantly in cafés, small storefronts and shared office kitchens across the city: a domestic under-counter refrigerator or a domestic dishwasher installed in a commercial setting.
We service it with the commercial approach, because that is what its duty cycle actually is. A domestic machine opened two hundred times a day is doing a commercial job whatever the nameplate says, and it will fail on a commercial schedule — pumps, gaskets, hinges and compressors, in that order.
It is worth knowing that going in. The equipment is not defective; it is being asked to do something it was not specified for.
What we cover
Reach-in and walk-in refrigeration, ice machines, prep tables, warewashing, and cooking equipment — Hoshizaki, Manitowoc, Scotsman, MaxxIce and Ice-O-Matic on ice production; True, Turbo Air, Atosa, Everest and Perlick on refrigeration; Hobart on warewashing; Vulcan on cooking.
The four checks worth doing yourself
- •Brush the condensers on a schedule, not when something goes wrong.
- •Check every door gasket with a dollar bill, monthly. It takes ten minutes for a whole kitchen.
- •Descale ice equipment to the manufacturer's interval, on Chicago water.
- •Clear the drains — refrigeration, ice, dish. All of them.
Between them those four prevent most of the calls we would otherwise be making, and every one of them is cheaper than the failure it prevents.
