Service illustration · not a completed customer projectTHE WORK, EXPLAINED
Start with the condition.
Understand the scope.
Ask which product, purpose, label-authorized use and system material are involved before considering a proposed chemical treatment. EPA does not recommend routine sealant use and identifies unresolved questions about these treatments. Request an explanation of alternatives, prerequisites and limitations from the responsible professional; this service guide is not product approval.
What may be involved
- product label
- duct material
- documented condition
- written justification
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 / East Palo Alto
Building history
The present city included Ravenswood and North Palo Alto in the early twentieth century, but did not incorporate until 1983.
Source ↗Local context
Its small, centrally located area sits near San Francisco Bay and major transport links, so commercial and residential calls can be close together.
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.
