What air duct cleaning costs
General cost ranges in the Knoxville area, and how to avoid the low-price bait.
What drives the price — and a warning
Honest duct cleaning is priced by the size of the system and the number of vents. Be wary of very low advertised prices ($49-type offers): they're often bait that turns into a high-pressure upsell once someone is at your home.
