What we do
Ten repairs we take on. Each repair on this list has a page of its own: the part of the equipment that actually gets replaced or rebuilt, how that job compares with the others, and when a unit that has run too many shifts is no longer worth the part and belongs on the replacement budget instead.

In the order it gets done: the cheapest cause first, and the expensive answer at the bottom where it usually belongs.
One visit finding why a cooler, fryer, oven, dish machine or laundry machine stopped earning its keep.
Walk-in coolers and freezers back to temperature: evaporators, fans, defrost, drain heaters, condensing units and doors.
Reach-ins, pass-throughs, prep tables and blast chillers: gaskets, hinges, fans, thermostats, condensers and compressors.
Gas and electric fryers back on the line: pilots, ignition, thermostats, high-limits, elements and filter pumps.
Convection, combi and rapid-cook ovens, steamers and kettles: blowers, steam generators, probes, igniters and controllers.
Griddles, charbroilers, restaurant ranges and hot tops: pilots, burners, orifices, valves and hoses, leak-checked after.
Undercounter, door-type and conveyor dish machines: tank heaters, boosters, wash pumps, fill and drain valves.
Coin, card and on-premise laundry machines and tumblers: door locks, bearings, inverters, burners and payment hardware.
Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so.
Scheduled visits across cold, cooking, warewashing and laundry: coils, gaskets, calibration, gas checks and a written log.
Before you bookBands rather than prices, because nobody can quote a figure before the commercial appliance has been looked at — and the diagnostic visit that decides it, set against the repair.
10 repairsCheapest firstDiagnostic visit Read the cost guideWeigh a repair against what a replacement truly costs the business, not just the catalog figure for a new unit. A new walk-in condensing unit, fryer battery, combi oven or dish machine also means delivery, the gas, water, drain or electrical connection, sometimes a hood or permit check, staff learning a new controller, and the shifts the station is down while you wait for it. Set beside that, gaskets, fans, thermostats, pilots, door locks and fill valves are small, and most mid-size repairs still win. The balance turns when a unit has had several major repairs in a year, runs on a refrigerant or a controller the maker no longer supports, or has a tank, shell or drum that is failing; then the technician writes out both sums, with the downtime each one costs, and the choice is yours. A preventive maintenance plan is the cheapest way to move repairs off the busy nights.
| Repair | Relative cost | Notes |
|---|---|---|
| Walk-in evaporator fan, defrost heater or drain line heater, door gasket, frame heater, expansion valve, leak repair, compressor or condensing unit | moderate to highest | An evaporator fan motor, a new door gasket or a defrost termination switch is the lighter end. A defrost heater set, a frame heater or an expansion valve sits in the middle, and a leak found, repaired and recharged, or a compressor or a whole condensing unit on the roof, is the top of the scale. |
| Reach-in, pass-through or prep table gasket, hinge, fan motor, thermostat or controller, defrost heater, leak repair or compressor | moderate | A cleaned condenser, a gasket or a hinge cam is modest. A fan motor, a thermostat or a controller with its probe comes next, and a leak repair with a recharge or a compressor in a self-contained cabinet is the fuller job. |
| Fryer pilot assembly, thermopile, thermostat or probe, high-limit, gas valve, ignition module, element, contactor or filter pump motor | low to moderate | A thermopile, a pilot assembly or a high-limit is the small end. A thermostat, a probe or an ignition module is a step up, and a gas valve, an element set or a filtration pump motor sits at the top. |
| Convection or combi blower motor, door switch or gasket, igniter or element, core probe, level probe, steam generator or controller | moderate to highest | A door gasket, a door switch or a probe is the lighter work. A blower motor, an igniter or an element comes next, and a steam generator, a descaling job that has gone too far or a main controller on a combi is the largest repair on this page. |
| Cooking line pilot, thermocouple, burner or orifice, safety valve, griddle thermostat, regulator or quick-disconnect hose, leak-checked | low to moderate | Cleaning a pilot or a burner and replacing a thermocouple is modest. A safety valve, a griddle thermostat or a regulator is in the middle, and several sections of a line, or a new hose with its restraint cable, make the fuller job. |
| Dish machine tank heater or booster element, thermostat, fill valve, float switch, drain valve, wash pump seal or motor, conveyor drive | moderate | A fill valve, a float switch or a drain valve is the small end. A tank heater, a booster element or a pump seal is a step up, and a wash pump motor, a booster tank or a conveyor drive on a long machine is the top of the band. |
| Laundry machine door lock, belt, bearings and seal, drain valve, inverter or motor; tumbler igniter, flame sensor, gas valve coil or airflow switch | moderate | A door lock, a belt, a drain valve cleared of coins or a tumbler igniter is the lighter end. An airflow switch, a gas valve coil or a payment reader sits in the middle, and bearings with the tub seal, an inverter or a drive motor is the fuller job. |
| Controller, touch panel, probe or sensor, relay, contactor, power supply, door switch or interlock, tested before anything is changed | moderate | A probe, a door switch or a contactor is modest. A relay board or a power supply is in the middle, and a main controller or a touch panel, set back up with your setpoints and cycle values, is the dearest part here. |
| Scheduled maintenance visit: coils and drains cleaned, gaskets and doors checked, thermostats calibrated, gas leak check, temperatures logged | lowest | A routine maintenance visit per unit is the smallest item on this page. Worn parts found along the way are quoted as their own repair, and nothing is replaced during the visit before you agree. |
Most people arrive knowing the symptom, not the repair. These are the jobs each one usually turns out to be, cheapest first — and every one of them starts with the commercial appliance diagnostic visit.
