Air Duct Cleaning Costs (2026)
Updated October 2026
Air duct cleaning runs $25–$50 per vent, $0.15–$0.35 per square foot, or $300–$600 flat per system — three published pricing models with three different bases. A whole-house “$99 special” is not the flat-per-system job; here's how to match any quote to the job it describes.
Duct cleaning cost at a glance
| How the job is priced | What it costs | Basis label |
|---|---|---|
| Per vent | $25–$50 each ($35 typical; up to $75/return) | price × number of vents cleaned |
| Per square foot | $0.15 low; $0.30–$0.35 high | rate applied to home square footage |
| Flat per system | ~$500 typical; $300–$600 band | one price regardless of vent count |
| Home size (1,000–3,000 sq ft) | $140–$1,050 (publisher tables) | per-home, by total square footage |
| Dryer vent (the sibling job) | $100 with a duct cleaning; $100–$170 standalone | per dryer vent |
Headline range: $271–$509 typical (HomeAdvisor live, avg $389), corroborated by Angi ($271–$508, avg $389). Larger or heavily-contaminated systems reach $800+; Thumbtack's market range runs $225–$619 (low $109, high $1,244) and Fixr averages $500 for a 2,000-sq-ft home.
Every row keeps its basis — the models are never averaged into one number. That's the whole point of this page.
The three pricing models (and why quotes differ wildly)
The same home can be quoted $35-a-vent, $0.15–$0.30-a-foot, or a flat $500 — and all three can be legitimate. They price different scopes, and the confusion between them is where the “$99 whole-house special” lives.
- Per vent — $25–$50 each (three publishers agree exactly, $35 typical). The contractor quotes a per-register price; your total = price × vents cleaned. Fixr adds a ceiling of up to $75 per return vent (larger, collects more debris). Best when your vent count is known and you want itemized scope.
- Per square foot — $0.15 low; the high splits $0.30 (HomeAdvisor/Angi) vs $0.35 (Fixr). A rate on total home area. A 1,500-sq-ft home lands $225–$450 on HomeAdvisor's table ($180–$360 on Angi's). The low rate is exact across all three; the high is kept as a band, never averaged.
- Flat per system — ~$500 typical ($300–$600 band). One price for the whole system, whatever the vent count. This is the honest baseline the “$99 special” is measured against — Fixr's live page warns that a too-low flat fee is the upsell hook (“such as duct or HVAC repairs”), and Angi flags the “blow-and-go” pattern.
The scam-check in one line: if a quote names a per-vent price on a job the contractor describes as flat-per-system (or vice versa), the basis and the job don't match — ask which basis the number is priced on before you compare it to anything.
Cost by home size
Home-size quotes differ by publisher edition and basis — kept per-source below, never merged.
| Home size | Fixr (live) | Angi (Wayback) | Thumbtack (banded basis) |
|---|---|---|---|
| 1,000 sq ft | $150–$350 | $140–$250 | $230–$537 |
| 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 | — |
| Under 1,000 sq ft | — | — | $191–$445 |
| Over 4,000 sq ft | — | — | $276–$643 |
Fixr and Angi agree exactly at 1,200 (upward) and at the 1,500 and 2,000 lows. Fixr's highs run higher (2,000 sq ft: $700 vs $600) — different editions, kept separate. Thumbtack publishes banded ranges (a different basis, not fixed sizes) — a separate row, not merged.
Dryer vent cleaning cost
Per the brief this lives inside this cluster as an H2, not a separate page.
- $100 added to an air-duct cleaning visit (HomeAdvisor and Angi, exact).
- $100–$170 standalone (HomeAdvisor and Angi, exact).
- Fixr: ~$140 average extra when bundled.
- Thumbtack: standalone average $283 ($185–$432) — a higher market-quoted basis, kept separate, never averaged with the $100–$170 band.
[GATED on a duct context-facts card] — the fire-risk framing and any annual-cleaning claim require the separate context-facts card; no fire/health claim ships from the dataset alone.
Is duct cleaning worth it? (EPA guidance)
[GATED on a duct context-facts card] — do not ship an EPA or health claim from this dataset. The dataset makes no health/fire claim as a priced row. The live publishers carry context (Thumbtack quotes EPA verbatim that duct cleaning “has never been shown to actually prevent health problems”; Angi notes EPA “no conclusive evidence” and a NADCA 3–5-year cadence), but the “is it worth it” section must cite the facts card, not this dataset.
This is the page's trust moat — the honest answer, not a campaign sell. It gates on the context-facts card.
How to hire (and the “$99 special” red flags)
Process guidance — no price claim:
- Ask which pricing basis the quote is on (per vent / per sq ft / flat) and make the contractor name it. A number without a basis can't be compared.
- Certification standard: ask about NADCA certification and see the certification; the live publishers cite NADCA cadence guidance (context — the cadence claim itself is gated).
- Red flags: a price far below the flat-per-system band with “repairs” hinted as an add-on; a per-vent price on a job described as flat; “blow-and-go” quick visits that don't clean trunk lines.
- Scope written down: vents cleaned, trunk lines, registers, and whether the dryer vent is included ($100 with the visit).

Duct cleaning is the maintenance side of the HVAC system your ducts serve. The dryer vent hangs off the same appliance loop as the ventilation and combustion air and the dryer circuit behind the vent.
FAQ
How much does air duct cleaning cost?

How much does it cost per vent?
$25–$50 per vent ($35 typical) — three publishers agree exactly. Return vents can run up to $75 each (Fixr).
How much is dryer vent cleaning?
$100 with an air-duct cleaning, or $100–$170 standalone (HomeAdvisor and Angi, exact). Thumbtack's standalone average is higher ($283) — a different basis.
Is duct cleaning worth it?
[GATED on a duct context-facts card] — the EPA-guidance answer needs the facts file; this dataset prices the job, it does not make a health claim.
How often should ducts be cleaned?
[GATED on a duct context-facts card] — cadence is convention, not a dataset row.
How do I avoid a duct-cleaning scam?
Make the contractor name the pricing basis (per vent / per sq ft / flat) and match it to the job they describe; ask about NADCA certification; and be wary of a flat quote far below the ~$500 baseline that hints at "repairs."
The EPA/fire/health claims and the cleaning-cadence answer are deliberately gated on a separate duct context-facts card — they are not in this cost dataset and are not invented.
