Mount Brydges Duct Cleaning

A rooftop unit and an older basement air system can differ in access, layout, and cleaning needs. Ask the assessor to identify the equipment covered, access constraints, and any areas excluded, then request a written price tied to that scope. If the building has multiple units or tenants, provide a site plan or equipment list where available; those details can materially change the work required.

If a musty smell appears seasonally, note its timing and check accessible areas such as the basement, equipment cabinet, and condensate drain for possible sources. Ask what evidence links the odour to duct surfaces and whether another inspection is appropriate. This can change the scope: treating ductwork without identifying a separate moisture or equipment issue may not resolve the underlying cause.

A leak on the supply side and one on the return side can have different effects, depending on location and system design. If a return runs near a basement or another unconditioned space, point out its route and ask whether testing supports a repair there. This conditional detail can change priorities and access needs; do not assume that a particular room’s dust proves a return leak.

If a property is near a busy road, fields, or wooded areas, those surroundings may be relevant when discussing dust and seasonal debris, but they do not establish that ducts need cleaning. Note when symptoms or visible buildup occur, check filters and returns, and ask how those observations affect the recommended scope and any suggested maintenance interval.

Note filter dimensions, unit location, and any replacement schedule shown in the equipment manual. Ask how to identify the correct filter and what maintenance interval the manufacturer recommends for the home’s operating conditions. A written record can make routine checks easier between professional visits. Do not rely on a general seasonal schedule without considering the unit instructions, filter type, and household use.
