Since 1980, Superior Service has protected over 1,200 California kitchens with commercial kitchen maintenance contract programs that prevent breakdowns, extend equipment life, and keep health inspectors happy.
9 out of 10 combi oven repairs are completed on the first visit. We ask about your brand and symptoms before we dispatch so our technicians arrive with the right parts already on the truck. That is what drives our 90% first-time fix rate.
30-day labor warranty on every repair. Written estimate before we start. Emergency response in 2–4 hours, 24/7.
A properly structured commercial kitchen maintenance contract is not just scheduled visits. It is a complete strategy to eliminate surprise failures, maintain warranty compliance, and extend asset life across your entire operation. Our commercial kitchen maintenance contract programs include quarterly PM visits with 47-point inspections, priority emergency response under four hours, all OEM parts at contractor cost, and detailed compliance documentation for health department audits. Every contract is customized to your equipment mix, service hours, and volume. We document every relay, every burner orifice, every evaporator coil so nothing gets missed across multiple visits.
Our technicians carry diagnostic tools for Vulcan, Southbend, Garland, True, Traulsen, Hobart, and Alto-Shaam equipment. Each PM visit includes gas pressure verification at manifolds, refrigerant charge analysis with superheat and subcooling calculations, door gasket integrity testing, burner combustion analysis, and safety interlock function checks. We calibrate thermostats to within two degrees, torque all electrical terminations to manufacturer spec, test all high-limit switches, verify conveyor belt tension on Middleby Marshall and Lincoln ovens, and clean condenser coils to factory airflow standards. You receive a digital report with photos, amperage readings, and replacement forecasts within 24 hours of every visit.
Average combi oven repair: $400–$800. Average day of lost revenue with a down unit: $500–$2,000. Getting it fixed today instead of waiting 2 days for the manufacturer pays for itself before we leave the parking lot.
Written estimate before any work begins. You approve the repair, we start. You don't approve, you owe nothing.

"We switched to Superior after our third fryer breakdown in six months. Their contract program caught a gas valve issue before it became a fire hazard."
"They identified a failing compressor on our walk-in during a routine visit. Replaced it scheduled instead of during Saturday brunch. Game changer."
"Superior's documentation is flawless. Inspector asked for refrigeration logs and we handed him 18 months of calibrated temps and PM records on the spot."
Many commercial kitchen maintenance contract providers send undertrained techs with generic checklists. We assign a dedicated senior technician who learns your equipment, your peak hours, and your specific failure patterns to deliver truly preventive service.
