Review the previous boundary
Ask whether the fan, coils, and relevant return and supply sections were assessed. An incomplete component scope can differ from a new contamination source.
Request duct cleaning for a property in Brampton. Include the equipment, the problem or planned work, and your location so the request can be reviewed.
Repeated cleaning is unlikely to settle a concern whose source remains in the property. Describe what returned, where it appears, and what the previous cleaning included. Inspection should distinguish duct contamination from filter issues, moisture, pests, or indoor dust sources before another cleaning package is purchased.
Keep the previous component list and completion evidence. Record water entry, building work, visible debris, and the timing of odours without claiming that appearance alone identifies mould.

Ask whether the fan, coils, and relevant return and supply sections were assessed. An incomplete component scope can differ from a new contamination source.
Source correction may be needed before cleaning. A qualified assessment should explain damaged or wet materials and any separate remediation responsibilities.
If deposits warrant removal, request the affected components, collection method, access restoration, and completion evidence. Optional chemical treatments need a separate explanation of suitability and purpose.
Compare source correction and a documented cleaning scope with another routine package. Do not rely on a guaranteed air-quality improvement or repeated calendar reminders as evidence that the same work should be purchased again.
Routine cleaning is not automatically necessary and does not guarantee health or energy benefits. Resolve moisture sources and assess damaged materials rather than treating cleaning as the only remedy.
Send the property location, equipment information, and requested work for review.
