Post-Cleaning Visual Check in Hayes Valley

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.

Discuss 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. Request a reason for any replacement and confirm compatibility with your equipment. A list of possible items does not mean that every item must be supplied or replaced.

A concern should start with an assessment of observed conditions. Visible debris, moisture, pests or another specific issue can justify a closer look, but a cleaning schedule alone does not establish that work is needed. Ask what was found and which parts of the system the proposal addresses.

Ask which supply and return sections, registers and accessible equipment are included, how access is obtained and how loosened debris is collected. Clarify exclusions, access limitations and any separate work on the air handler. A quote for vents alone may describe a different scope from a whole-system proposal.

An odor description helps prepare the visit but does not establish its source. Explain where and when you notice it and whether it changes with system operation. Ask how the assessment will distinguish duct conditions from other possible sources before agreeing to cleaning or treatment.

Request photographs or documented observations of the relevant accessible areas and a clear explanation of the proposed scope. Ask which findings were directly observed and which areas could not be accessed. Generic sample images are not evidence of your own system’s condition.

Identify the air-handler location, note the number of systems if known and explain any access restrictions. Keep access to registers and equipment clear. Gather previous work records and describe the particular concern so the visit can focus on useful observations.

EPA advises a thorough visual inspection and a demonstration of the system components after cleaning. Ask the provider to walk through the agreed checklist and identify which surfaces the evidence shows.

Ask for photographs to be labelled by component and location, with before-and-after views where available. Keep the coverage explicit so an image from one accessible section is not presented as a record of every section.

Record the uninspected section and the reason it could not be checked. Ask how that limitation affects the completion report and whether a separate follow-up is proposed. Do not label an unseen section as verified clean.

EPA advises asking the provider to correct deficiencies found using its checklist. Record the specific component and observation, and agree how the correction will be demonstrated before closing that item.
