Start with a reason, not a calendar
The EPA recommends duct cleaning when needed, rather than on a fixed routine. Substantial mold growth, pest infestation, or heavy debris released through registers can justify assessment. Cleaning has not been shown to prevent health problems.
Make your first conversation useful
Write down what you have noticed, which rooms are affected and when the issue started. Mention recent building work, unusual odors or any known water damage. These details help explain your concern without deciding the solution in advance.
Ask to see the findings
Ask the contractor to explain what they found in your system and why they recommend cleaning. Request photographs linked to the relevant area of your home, and ask what other issues need attention.
Compare the whole proposal
A useful quote identifies the system, the work included, the proposed method, exclusions and the total price. Ask who will do the work and whether any additional services require your approval.
