Sub-Zero & Wolf Repair San Diego

Preventive maintenance frequency depends on the equipment and usage volume. As a general guideline: fryers and ovens should be inspected every 3-6 months; refrigeration equipment annually or semi-annually; ice machines every 6 months (including cleaning and sanitizing); exhaust hoods quarterly to semi-annually per NFPA 96; and dishwashers quarterly. High-volume operations benefit from more frequent service intervals.

Combi oven steam issues are commonly caused by: clogged steam generator or boiler scale buildup, failed heating element in the steam generator, water inlet valve problems, or steam nozzle blockages. Mineral scale from hard water is the most common culprit and can be prevented with regular descaling. A combi oven specialist should inspect the steam system as improper repairs can damage the boiler.

Installation costs vary widely: single appliance installation $300-$2,000 depending on complexity (simple drop-in vs. gas/electrical connections required); complete kitchen buildout $15,000-$75,000+. Costs include equipment setting, utility connections (gas, electric, water, drain), ventilation hookup, and commissioning. Always get installation quotes separate from equipment costs — some dealers include installation, others charge separately.
