Duct sanitizing and deodorizing
When disinfection makes sense — and when it's just an add-on.
Sanitizing is worthwhile after mold or a rodent problem, where there's an actual biological reason. As a routine add-on with no underlying issue, it's often more upsell than benefit.
An honest provider will draw that line for you.
When sanitizing a Knoxville duct run is not an upsell
This site is already blunt: sanitizing is worthwhile after mold in the system or a rodent problem, and as a routine add-on with no underlying issue it is often more upsell than benefit. Humid-summer allergen talk makes it an easy extra to attach to a duct-cleaning visit. A referred provider should draw that line before they spray; this site does not sell the add-on.
