Eleven questions to ask before booking
Review before arrival, then connect the observation to its source, system location, and a written scope.
DIRECT ANSWER
Start with the condition, not the sales package
A short call can reveal whether the provider begins with evidence or a package. Describe the observation, not your conclusion. Say which rooms are affected, when the system runs, and whether there was water, pests, smoke, or renovation. Then ask the same questions of more than one provider.
Do not share sensitive medical details to justify a service. Duct cleaning has not been shown to prevent health problems. If symptoms are severe or urgent, seek appropriate medical or emergency advice rather than relying on a cleaning salesperson.

What deserves a closer look
At inspection
Ask whether findings will be shown before work, how duct material is identified, and whether you can decline the cleaning after inspection.
In the agreement
Ask for component scope, access, method, products, protection, cleanup, price, change approval, result documentation, and correction process.
