Start with the condition.
Understand the scope.
Ask which accessible portions will be visually checked, how the findings will be recorded and which portions remain unverified. EPA identifies visual inspection as the main way to check cleaning results. Agree how unresolved debris or access limits will be handled without treating inaccessible areas as inspected.
What may be involved
- accessible ducts
- registers
- air-handler housing
- documentation
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 / Potrero Hill
Housing context
Planning identifies this area among neighborhoods containing RH-1 one-family residential zoning, so individual-home hardware is part of the local mix.
Source ↗Local context
The Showplace Square/Potrero Hill Area Plan describes historic brick buildings and production businesses in Showplace Square, mixed-use development at the base of the hill, and a predominantly residential character on Potrero Hill. These adjoining settings do not establish the age or condition of a property’s equipment.
Source ↗Area-wide context does not establish the condition of your property or equipment.
Before the visit
Building age and weather cannot establish duct contamination. The system itself needs to be inspected.
