Before hiring
- Get more than one written estimate
- Confirm the vent and return count
- Ask how many HVAC systems are included
- Ask what cleaning equipment and agitation method will be used
- Confirm insurance and any licensing required in your area
- Read the exclusions and optional services
Useful quality signals
Relevant training, established duct-cleaning experience, NADCA membership or certification, clear insurance information, and a detailed written scope can all be useful signals. None of them replaces reading the actual quote.
Questions after the job
Ask what was cleaned, whether any areas could not be accessed, whether damage or moisture was found, and whether the company can show before-and-after documentation for the areas it serviced.
Sources and methodology
We use current consumer cost references for price ranges and primary EPA or NADCA guidance for safety, cleaning scope, and homeowner precautions when available. Published prices are planning benchmarks, not contractor quotes.

Price the actual job, not the headline number.
Use your vent count and ZIP to build a planning range, check researched local benchmarks, then compare nearby contractor options.
