THE WORK, EXPLAINED
Start with the condition.
Understand the scope.
Identify the accessible housing surfaces covered by the proposal and the documented debris. Ask which adjacent components are included, which require separate HVAC work and what access limits apply. Confirm the collection approach, protection of retained components and completion records before agreeing to the scope.
What may be involved
- air-handler housing
- access panel
- vacuum collection
- seals
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 / Chinatown
Building history
The area rebuilt on its original site after 1906, and some buildings reused original brick; its historic fabric includes many early post-earthquake structures.
Source ↗Housing context
The Chinatown Area Plan describes predominantly low, small-scale buildings, with many buildings relatively short in depth because of the lot pattern. This describes the district’s built form, not the equipment or condition of an individual property.
Source ↗Local exposure
The City identifies Chinatown as comparatively sunny and sheltered from wind, rather than treating it as a typical fog-exposed district.
Source ↗Local context
The plan records more than 250 historically or architecturally important early post-earthquake buildings, so preservation-sensitive work is a realistic consideration.
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.
