How Much Does Air Duct Cleaning Cost? (2026)
Updated October 2026
Air duct cleaning typically costs $271–$509 (average $389), with most homes landing in that band. It's also quoted $25–$50 per vent, $0.15–$0.35 per square foot, or ~$500 flat per system — three legitimate pricing models with different bases. Larger or heavily-contaminated systems reach $800+; dryer-vent cleaning adds $100 to a visit or runs $100–$170 standalone.
What duct cleaning actually includes
A legitimate job is not a quick blow-through. The scope is vent-by-vent:
- Supply and return vents/registers — vacuumed and cleaned individually (this is why per-vent pricing exists — the work scales with vent count).
- Trunk lines and branch ducts — the main runs, cleaned with rotary brushes/negative-air equipment.
- Registers/grilles and the air handler area — registers removed or cleaned; the furnace/AC area and drain pan reached where accessible.
Because scope scales with vent count and home size, the three pricing models all describe the same work from different angles — which is exactly why a quote must name its basis before you can compare it. [GATED on a duct context-facts card] for the method/equipment specifics — see the DIY section.
Cost by pricing model
The three bases, side by side — never blended.
- Per vent — $25–$50 each ($35 typical). Three publishers (HomeAdvisor, Angi, Fixr) agree exactly on the $25–$50 band. Return vents can reach $75 each (Fixr: larger, collect more debris). Total = price × vents cleaned. Example: 12 vents × $35 ≈ $420.
- Per square foot — $0.15 low; high $0.30 (HomeAdvisor/Angi) vs $0.35 (Fixr). The low rate is exact across all three. Worked examples:
Home HomeAdvisor Angi Rate basis 1,500 sq ft $225–$450 $180–$360 $0.15–$0.30 2,000 sq ft — — Fixr average $500 at 2,000 sq ft - Flat per system — ~$500 typical ($300–$600 band). One price regardless of vent count. Fixr's live page calls ~$500 what “most homeowners would pay”; the scored $300–$600 band sits inside it. This is the baseline the “$99 whole-house special” is measured against.
Vent-count table (Fixr and Angi publish the identical table):
| Vents | Cost | Thumbtack (banded basis) |
|---|---|---|
| 8 vents | $200–$400 | — |
| 12 vents | $300–$600 | $303–$708 (11–20) |
| 16 vents | $400–$800 | $303–$708 (11–20) |
| 20 vents | $500–$1,000 | $303–$708 (11–20) |
Why quotes differ wildly: the same home quoted “$35/vent” and “flat $500” are the same job priced on two bases. Match the basis to the scope the contractor describes before comparing numbers.
Cost by home size
Publisher size tables (per-source, never merged):
| Home size | Fixr (live) | Angi (Wayback) | Thumbtack (banded) |
|---|---|---|---|
| 1,000 sq ft | $150–$350 | $140–$250 | — |
| 1,200 sq ft | $180–$420 | $180–$360 | — |
| 1,500 sq ft | $225–$525 | $225–$450 | — |
| 2,000 sq ft | $300–$700 | $300–$600 | — |
| 2,500 sq ft | $375–$875 | — | — |
| 3,000 sq ft | $450–$1,050 | $450–$900 | — |
Fixr and Angi agree exactly at 1,200 upward and at the 1,500/2,000 lows; Fixr's highs run higher (2,000 sq ft: $700 vs $600). Thumbtack publishes banded ranges on a different basis (under {usd(tt.lt_1000[0])}–{usd(tt.lt_1000[1])} · 1,000–2,000 {usd(tt["1000_2000"][0])}–$537 · 2,000–3,000 {usd(tt["2000_3000"][0])}–$572 · 3,000–4,000 {usd(tt["3000_4000"][0])}–$633 · over 4,000 {usd(tt.gt_4000[0])}–$643).
Dryer vent cleaning cost
- $100 added to an air-duct cleaning visit (HomeAdvisor and Angi, exact).
- $100–$170 standalone (HomeAdvisor and Angi, exact).
- Fixr: ~$140 average extra bundled.
- Thumbtack: standalone average $283 ($185–$432) — a higher market basis, kept separate.
[GATED on a duct context-facts card] — the fire-risk framing for this section (why a clogged dryer vent matters) requires the context-facts card; the dataset prices the job, it does not source the fire claim.
When it's worth it — and when it isn't
[GATED on a duct context-facts card] — do not ship an EPA or health claim from this dataset. The honest published context (Thumbtack quotes EPA verbatim that duct cleaning “has never been shown to actually prevent health problems”; Angi notes EPA “no conclusive evidence”) points to a nuanced answer: cleaning is justified in specific conditions and oversold as routine. The condition list and any EPA citation must come from the facts card.
This is the article's moat — answer honestly, don't sell a campaign. Gates on the context-facts card.
DIY vs professional
The honest boundary [GATED on a duct context-facts card] for method specifics:
- Often DIY-able: register/grille wipe-down and dryer-vent lint removal (accessible sections).
- Professional: trunk lines, the air handler/drain pan, and HVAC-coil-area work — these need rotary/negative-air equipment and access most homeowners don't have.
- Why the boundary matters: per-vent pricing exists because vent-by-vent work is the professional scope; a “cheap” quote that skips trunk lines is the blow-and-go pattern. Method detail beyond this gates on the facts card.
Hiring checklist
- Name the basis: per vent / per sq ft / flat — make the contractor say which.
- NADCA certification: ask and see it (context basis; the cadence claim is gated).
- Scope in writing: vents, trunk lines, registers, air handler area; dryer vent included? ($100 with the visit.)
- Red flags: flat quote far below ~$500 with “repairs” hinted; per-vent price on a job described as flat; no trunk-line cleaning in scope.
- Second quote: because the three bases coexist, two quotes on different bases aren't comparable until you convert them.
