THE SHORT ANSWER
What does this service involve?
A duct condition assessment documents accessible HVAC components before cleaning is proposed. Ask to see what was observed, where it was found and what the recommended work would address. Dust at a grille alone is not a complete picture of the system, and an assessment is not a medical diagnosis.

A scope you can understand.
Describe the concern
Explain visible debris, moisture, pests or recent renovation work. Identify when and where the issue appears.
Look at accessible components
Ask which supply and return sections, registers and air-handler components can be assessed, and which areas cannot be reached.
Agree on an evidence-based scope
Request images tied to component locations and a written explanation of proposed cleaning, repair or referral. A finding should lead to a specific next step.
Confirm these tasks with the provider. The final scope depends on the equipment and observed condition.
SYMPTOM ≠ DIAGNOSIS

LOCAL RESEARCH / Miami
Local context
Miami-Dade County's mechanical permits page tells applicants to check its permit exemption information to verify whether a mechanical building permit is required, and says a completed building permit application and a mechanical fee sheet must be submitted as part of an application, with plans submitted for plan review where a category indicates it needs processing. The page itself does not list which mechanical work is covered. Ask the department covering your address whether the proposed duct work counts as exempt repair or as permitted work before it starts.
Source ↗Planning your work
Miami-Dade County's permit exemption list states that repair of air conditioning duct is exempt from permit requirements regardless of the value of materials and labour when performed by a licensed mechanical contractor, and separately that changing out air conditioning equipment of the same electrical, cooling or heating capacity does not need an electrical permit but that a mechanical permit is required for the change out. That list carries an update date and says it applies to unincorporated Miami-Dade County. Cleaning is not the same thing as duct repair or equipment replacement, so ask a provider which category the proposed work falls into. Confirm the address, the proposed scope and the applicable review with the City of Miami; neighbourhood names do not always follow city limits, so check which building department covers your address.

Questions worth asking.
Should every home have routine duct cleaning?
EPA does not recommend duct cleaning as routine maintenance. It advises considering cleaning in specific circumstances such as substantial visible mold, pests or excessive debris.
Can cleaning guarantee better health?
No health improvement is promised here. EPA says duct cleaning has not been shown to prevent health problems. Discuss health concerns with an appropriate clinician.
What if ducts need replacing?
Ask for condition evidence and a separate replacement scope. Confirm project-specific requirements with the installer and relevant local authority.
