Air Duct Cleaning Markham, ON
If a home in Markham has recently been renovated or built, construction dust may have entered its supply and return ducts. Older systems can also collect ordinary household debris over time. Before requesting a quote, note which rooms have registers, whether the system has accessible trunk lines, and whether recent work produced dust. Ask what equipment will collect loosened debris under negative pressure and whether the scope includes both supply and return sides. Photos of accessible duct interiors can help document the work.
Could renovation debris or dust be in your ducts?
If dust returns quickly after cleaning or renovation, inspect accessible registers and ask whether both supply and return ducts need attention. The system layout and amount of debris affect the work required.
Compare Supply and Return Scope
Ask whether the proposed work includes supply runs, return runs, trunk lines, and boots. Negative-pressure collection can help capture loosened debris rather than allowing it to spread through the home. Photograph registers and accessible duct openings before work, and confirm which parts of the system the estimate includes.
Request Useful Before-and-After Photos
Ask which duct interiors can be photographed and whether the pictures will be taken at comparable locations before and after cleaning. Photos can help you understand visible conditions and what was reached, but they do not document every hidden section. Keep copies with renovation or maintenance records.
Check for Post-Construction Debris
If drywall sanding, cutting, or other dusty work took place, tell the estimator when it happened and whether registers were covered. Ask whether construction debris is visible and how the proposed equipment will collect it. This information helps distinguish a post-renovation scope from routine cleaning and clarify access needs.
