Start with the condition.
Understand the scope.
Identify the supply runs and outlets covered by the proposal and the documented condition that prompted it. Ask how the proposed agitation and collection approach suits the duct material and access available. Confirm whether outlet cleaning, opening restoration and a record of the completed work are included.
What may be involved
- supply ducts
- supply registers
- vacuum collection
- soft brushes
Ask the provider to distinguish existing parts to inspect, proposed replacements, and tools, materials or reports included in the service. Confirm the work and exclusions after assessment; this list does not mean that every item will be supplied or replaced.
LOCAL RESEARCH / Winter Garden
Local context
The EPA does not recommend that air ducts be cleaned routinely, but only as needed, and names three situations where cleaning may be appropriate: substantial visible mold growth inside hard-surface ducts or on other components, ducts infested with vermin, and ducts clogged with excessive dust and debris where particles are actually released into the home. The EPA also notes that no chemical biocides are currently registered for use in internally-insulated air duct systems, and does not recommend routine use of sealants to encapsulate contaminants. Ask which of those conditions was observed before agreeing to any work.

Before the visit
Building age and weather cannot establish duct contamination. The system itself needs to be inspected.
