Duct Sanitizing & Deodorizing Markham, ON
Persistent odours in a Markham home can come from duct residue, but they can also originate from a drain, appliance, building material, or another source. Describe when the smell occurs and whether it is strongest near particular registers. If considering a duct treatment, ask what cleaning must happen first, which product is proposed, and how it will be applied. Request the product label and directions, including any stated re-entry precautions. A treatment should not be presented as a substitute for finding the odour source.
Does an odour return when the system runs?
Odours can come from ducts or other sources. Note when and where they occur, and ask whether inspection and cleaning should precede any treatment.
Describe the Odour and Its Source
Record whether an odour resembles smoke, cooking, pets, or a musty smell, and whether it appears only when heating or cooling runs. These details can guide an inspection, but do not prove the ducts are the source. Ask what other likely sources should be ruled out before agreeing to a duct treatment.
Clean Before Considering Treatment
Ask whether the ducts will be inspected and cleaned before any sanitizer or deodorizer is applied. Dust and residue can prevent a product from reaching duct surfaces, so treatment over debris may not suit the stated purpose. Confirm which surfaces are included and why the proposed product is appropriate for that use.
Request Product and Safety Details
Before application, request the product name, label directions, intended use, and any stated ventilation or re-entry precautions. Verify that the planned method follows the label and ask what areas will be treated. This information lets you understand what is being used in your home without assuming that a treatment eliminates an odour or provides a health benefit.
