Vent Sanitation in Winnipeg
Applied after duct and HRV cleaning to address odor sources and microbial buildup that vacuuming alone doesn't fully resolve.
What is vent sanitation and do I need it?
Vent sanitation is an antimicrobial treatment applied to duct surfaces after physical cleaning, addressing odour and microbial buildup that vacuuming alone does not remove. Bison Maintenance Services includes it in the $150–$300 Whole-Home Air System Bundle. It matters most for homes with a persistent musty smell, past moisture problems, or pets.
Physical duct cleaning removes dust, debris, and loose particulate — but it doesn't necessarily address odor sources or microbial buildup on interior duct surfaces, especially in systems that have had moisture exposure at some point (a past humidifier issue, a basement that's had dampness, or just years of condensation cycling near the furnace). Sanitation is a separate treatment step, applied after physical cleaning, aimed at that layer of the problem.
This matters most for a specific set of situations: homes with a persistent musty smell that doesn't clear up after normal cleaning, homes that have had past water intrusion or humidity issues, homes with pets, or households where someone has respiratory sensitivities and wants an extra layer of attention beyond a standard duct clean. It's not something every home strictly needs, but it's a meaningful add-on where odor or moisture history is a factor.
We apply sanitation treatment as a follow-up step after duct and/or HRV cleaning, not as a standalone substitute for physical cleaning — treating a dirty duct without removing the dust and debris first doesn't address the underlying buildup, it just treats what's sitting on top of it.

Why it matters
A musty smell that lingers after normal cleaning is usually a sign the issue isn't just loose dust — it's something on the surfaces of the duct system itself. Sanitation is the step that addresses that layer, which matters most for households dealing with persistent odor, past moisture problems, or heightened sensitivity to indoor air quality.

Sanitation is included as a step within our Whole-Home Air System Bundle — duct, furnace/HRV cleaning, sanitation, and dryer vent cleaning together for $150–$300 depending on home size.
