Service illustration · not a completed customer projectTHE WORK, EXPLAINED
Start with the condition.
Understand the scope.
Have the duct material identified before discussing a cleaning approach. Ask how the proposed equipment suits that material and which damaged or inaccessible sections need a separate assessment. Compare any repair or replacement recommendation with the condition record rather than assuming all duct construction can be treated alike.
What may be involved
- sheet metal duct
- flex duct
- fiberglass liner
- duct board
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.

Planning your work
California’s energy code can require HERS field verification and diagnostic testing on heating and cooling work. The California Energy Commission says that, depending on the work being done, HERS testing may be mandatory, and that properly permitted work will trigger any necessary HERS testing. It adds that a contractor should be able to explain permitting requirements to the homeowner and that HERS testing should be part of that discussion, and that a rater should identify themselves with a photo badge. Ask early whether the proposed work is a duct or equipment alteration that needs a permit, because cleaning and replacement are not the same scope. Confirm the permit position with the City of Morgan Hill.

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