$100–350 per vent is the 2026 US band, with about $150 the typical stop (Angi averages ~$140, Homewyse books $171–392, Thumbtack's national average lands at $307 with most pays near $200). Location moves the number: second-floor vents run $110–185 and roof vents $150–250 (Angi) because of the lift and ladder time.
The $99-or-less door-hanger price is a loss leader: the tech arrives, finds a "code violation" or a packed line, and the real invoice lands at $300+ (TopAir and several consumer guides document the pattern). Legitimate ops quote the band above up front. If a price sounds too cheap to pay for a truck roll, it is.
Run length and lint load. A 20-foot run to a roof cap with a decade of compaction needs snaking, not a leaf blower — Thumbtack's upper range reaches $510. Quote the snake work as its own line so the customer sees why. Whole-system duct cleaning is a different job ($350–1,000) — sell it as an upsell, never as the same service.
Once a year for most households; every 6 months for large families, pets with hair, or long vertical runs. The telling symptom is cycle time: if towels need two cycles, the vent is paying for it in energy — cleaning pays itself back before the fire risk even enters the pitch.
| Job | Typical US range (2026) |

In 2026 US data: $100–350 per vent with ~$150 typical (Angi ~$140, Homewyse $171–392, Thumbtack average $307). Second-floor vents run $110–185 and roof vents $150–250 (Angi); heavy lint or long runs price to ~$510.
Yes on cycle time alone: a clogged vent makes every load run longer, and the energy waste typically pays back the ~$150 cleaning within a year. The fire-risk reduction (lint is the leading cause of dryer fires) comes on top.
The advertised price rarely covers the truck roll. The pattern (documented by consumer guides and operators) is a low teaser price, an on-site "code violation" finding, and a final invoice of $300+. Reputable companies quote within the $100–350 band before starting.
Annually for most homes; every 6 months for large households, homes with shedding pets, or long/vertical vent runs. Longer dryer cycles are the early-warning sign that the line is packing.
