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 time varies significantly: single appliance with existing connections 2-4 hours; single appliance requiring new utility connections 4-8 hours; full kitchen buildout 1-3 weeks depending on scope, permit timelines, and contractor scheduling. Work with your installer to create a realistic timeline that accounts for utility work, inspections, and health department walkthroughs before opening.

Hood cleaning costs range from $300 to $1,500+ depending on system size, grease accumulation, and accessibility. Small single-hood systems run $300-$500; larger multi-hood systems or restaurants with heavy cooking can run $700-$1,500. Access issues (long duct runs, high roofs) add cost. Budget for cleaning as a fixed operating expense — it's far less expensive than a grease fire, insurance claims, or health violations.
