Air Duct Cleaning Questions

Check a return vent: pull the cover and look inside with a flashlight. A light film of dust is normal; a fuzzy grey coating, visible debris, a musty smell when the system runs, or dust that returns days after cleaning are the real signs. If you are not sure, our camera inspection shows you the inside of your own ducts before you decide anything.

It depends on the size of the system, the vent count and the condition we find — which is why we quote a fixed number for your home before work starts, with no per-vent surprises added later. Call (855) 640-0404 for a quote, and ask about the current seasonal offer: free dryer vent cleaning bundled with a full-system cleaning.

Most homes take 2–4 hours for a full-system cleaning. Larger homes and commercial systems take longer; we give you a realistic window before we begin.

No. The system is sealed under negative pressure while we work, so debris travels into our HEPA-filtered vacuum — not into your rooms. Vent covers are removed, washed and reinstalled.

Yes — if you are not happy with what the after-photos show, we re-clean the affected runs. And every recommendation we make is backed by camera photos from your own ductwork, never a sales script.

Most homes take 2–4 hours depending on size, vent count and how much buildup we find. We will give you a realistic time window before we start.

No — the system is sealed under negative pressure the whole time, so debris travels into our vacuum, not into your rooms. We also protect floors and furniture around every vent we open.

Yes — evenings and weekends are standard for our commercial clients. Your customers and staff never see us.

Yes. Every commercial job includes before-and-after photos from inside the ducts and a service summary for your records.

Once a year for most households. Large families, pet owners and long vent runs should stay on a strict annual schedule.

Loads taking two cycles, clothes hot but still damp, a burning smell, the laundry room getting humid, or the exterior flapper barely opening while the dryer runs.

We use EPA-registered products labelled for HVAC use and follow their dwell and re-entry directions exactly. We will tell you precisely when it is fine to be back in each room.

No — sanitizer cannot work through a layer of dust and debris. It is a finishing treatment applied after a proper mechanical cleaning.

Dust and debris load, mould-like growth, standing water stains, crushed or disconnected ducts, construction debris, pest nests and objects kids have dropped down vents over the years.

Yes. If the camera shows a clean system, we say so — an inspection that ends with 'you don't need us yet' is a good inspection.

No — and anyone who promises that is overselling. What it does is remove a major indoor reservoir of the triggers, which many sensitive households feel as less dust, fewer musty odours and easier mornings. It works best alongside good filtration and regular cleaning.

Yes — our vacuum exhaust is HEPA-filtered and the system stays under negative pressure, so removed material does not enter your rooms during the job.
