In a commercial kitchen, a failed unit is not an inconvenience — it is lost service, spoiled stock and, if it is refrigeration, a compliance problem. The economics of repair are completely different from a home kitchen, and so are the priorities.
The real cost is downtime, not the invoice
A reach-in that fails on a Friday afternoon can cost more in one service than the repair does. That changes the calculus in two ways: speed matters more than price, and preventive maintenance pays for itself in a way it rarely does domestically.
What fails most, and what it usually is
Reach-in and undercounter refrigeration
The most common commercial call. Usual causes: condenser coils choked with grease and dust, failed condenser or evaporator fans, door gaskets that no longer seal after thousands of daily openings, and defrost system failures. Grease-laden air is the defining difference from domestic refrigeration — coils clog far faster.
Deep fryers
Not reaching or holding temperature usually points to the thermostat, the high-limit control, the igniter or gas valve on gas units, or heating elements on electric. A fryer that will not hold temperature is also a food-safety issue, not just a quality one.
Commercial dishwashers
Failure to reach sanitising temperature is the one that fails inspections. Common causes are the booster heater, the thermostat, scale build-up on elements, and wash/rinse arm blockages.
Ice machines
Low or no production traces to water supply issues, scale in the system, a failed water inlet valve, dirty condenser coils, or the control board. Ice machines need scheduled descaling far more than owners expect.
Medical-grade refrigeration
Here the whole point of the unit is holding an exact range, so a drift that a restaurant would not notice is a failure. Temperature-monitoring and calibration matter as much as the mechanical repair.
The maintenance that actually prevents calls
- Clean condenser coils on a schedule — monthly in a busy kitchen, not annually. This single item prevents more refrigeration failures than everything else combined.
- Check door gaskets weekly. They are cheap, they fail constantly, and a bad one makes the compressor run continuously.
- Descale anything that heats water — dishwashers, ice machines, combi ovens — on the interval your water hardness dictates.
- Log temperatures. A drifting unit shows up in the log days before it fails outright.
- Keep airflow clearances. Stock stacked against a condenser is a guaranteed callback.
What to have ready when you call
- Equipment type, make and model.
- How long it has been failing and what changed.
- Whether it is holding any temperature at all.
- Your service window — when a technician can realistically work on it.
How we work with commercial accounts
Commercial refrigeration and cooking equipment gets priority scheduling because the cost of waiting is different. We invoice business accounts rather than taking payment on the day, and we will work around your service window where the equipment allows it. Details on the commercial appliance repair page.
Talk to a technician
If you would rather have someone look at it, we cover New York City and North and Central New Jersey. Call 888-777-6918 or send a booking request. The trip charge starts at $95 + tax and includes the in-home diagnosis.
