A hood motor is a hood motor whatever name is on the appliance, and the ventilation pages here are priced accordingly. What genuinely costs more on this equipment is a professional chassis somebody has to work around in place, an induction generator that is a power supply in its own right, and a steam oven with plumbing inside an oven cavity. Those three are the expensive rows and the pages say why.
Where a job is cheap on this equipment — a knob, a filter, a burner cap seated wrong, most induction call-outs — the page says that too, and says it before you have paid for a visit to hear it.
