The quick answer
Visible debris, a known contamination event or a change in system behavior can justify a closer look. A dusty grille or a high utility bill alone does not establish that the ducts need cleaning.
Start with something you can show
Write down what you noticed, where it happened and whether the system was running. A photograph from a safely accessible opening is more useful to an estimator than a general description of a dusty home. Leave sealed panels and inaccessible equipment for the technician.
- Debris actually coming from a supply opening
- A pest problem involving the ventilation system
- Visible material that needs identification
- Construction dust that may have entered exposed ductwork
- A persistent airflow concern that needs diagnosis
Ask what the inspection found
Ask the provider to distinguish dust at the grille from material deeper in the system. Request the location of any finding and the reason for the proposed work. The EPA describes particular contamination conditions that may warrant cleaning; it does not recommend routine cleaning for every home. EPA: deciding whether duct cleaning is needed.
Match the next step to the finding
A damaged duct, dirty filter and blocked return are different problems. Your estimate should explain whether the next step is cleaning, equipment maintenance or repair. If cleaning is proposed, identify the supply and return ducts and any HVAC components included. For a condo, establish who controls the equipment before authorizing work.
