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 / Pacifica
Local exposure
The air district’s 2011 regional climate description notes frequent cool, foggy summer weather in coastal Peninsula towns. This is regional outdoor context, not an assessment of a property’s equipment or indoor conditions.
Source ↗Local context
Where duct or HVAC work is permitted in California, independent field verification can be part of closing the permit. The California Energy Commission's Home Energy Rating System page says that depending on the work being done HERS testing may be mandatory and that properly permitted work will trigger any necessary testing, that a homeowner has the right to find and hire a rater who is independent of the contractor, and that suspected asbestos in duct insulation or sealing can exempt some tests, including duct leakage testing. Ask early whether the proposed scope is cleaning alone or work that would trigger verification.

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