Exact entity
A similar business name is not enough. Match the agreement, advertisement, vehicle, and CSLB record to the same legal or registered entity.

Check the exact California contractor when licensing applies
Review exact entity, then connect the observation to its source, system location, and a written scope.
DIRECT ANSWER
Start with the condition, not the sales package
California licensing depends on the work, permit requirements, labor, and contract value. A standalone cleaning question can become licensed HVAC or construction work when the proposal adds duct replacement, equipment alteration, repair, or installation. Do not assume that a cleaning advertisement authorizes every added task.
Use the CSLB lookup to check the exact name and license number on the agreement. Review status, classification, personnel, bond and workers' compensation information, and any disclosed complaint information that the tool provides. Ask Sunnyvale about permits when equipment or duct alterations are proposed.
