How Much Does AC Duct Cleaning Cost?
AC duct cleaning costs $300-$500 for a typical home with 6-10 vents. Larger homes with more vents run $500-$800. The price includes cleaning all supply and return ducts, registers, and the main trunk lines. Add $50-$150 for dryer vent cleaning if bundled. Avoid companies advertising $99 whole-house duct cleaning — these are typically bait-and-switch operations.
THE DETAILS
Duct cleaning pricing depends on the number of vents, accessibility of ductwork, and the level of contamination. Most Pittsburgh homes with standard duct systems fall in the $300-$500 range.
The process takes 2-4 hours. Technicians use specialized vacuums and brushes to clean inside the duct system, removing dust, debris, pet dander, and mold.
The EPA says duct cleaning is not always necessary and does not measurably improve air quality in most homes. However, it is worth doing if you see visible mold in ducts, notice dust blowing from vents, have had a rodent or insect infestation in the ductwork, or just moved into a home and do not know the history.
Be wary of extremely low prices. Companies advertising $99 or $149 whole-house duct cleaning often upsell aggressively once they arrive, sometimes quoting $1,000+ for mold treatment or sanitizing that may not be necessary.
