Quick math: a 12-vent home lands at $300 to $600 under all three references – 12 vents x $25 to $50 each (our math), matching their published tables exactly. If a quote for that home comes in far above $600, ask what is driving it: returns ($40 to $75 each), heavy contamination, or hard-to-reach ductwork.

Where they disagree: the whole-house averages sit $389 to $500+ apart in method, not market – Angi’s $389 comes from 21,664 real projects, HomeGuide cites the EPA/NADCA estimate of $450 to $1,000, and Fixr’s $500 assumes a 2,000 sq ft home. On a 2,000 sq ft home specifically the tables span $300 to $800 depending on whose per-square-foot rate the pro uses. Per-vent pricing is the one true consensus: all three publish $25 to $50 per supply vent and identical vent-count tables.1,2,3
What pushes the price up
Pricing model: the same home prices differently by vents versus square footage – count your vents before getting quotes so you can cross-check both models.1,2,3
Duct type and access: rigid metal ducts clean fast; flex ducts and tight crawl spaces need special equipment and more labor, per Angi and HomeGuide.1,2
Contamination: pest removal adds $200 to $1,200 and mold remediation $1,100 to $3,400 per Angi – full remediation is a separate job, not a cleaning.1
Household habits: pets, smoking and long gaps between cleanings add buildup and labor hours, per Angi and HomeGuide.1,2
Three worked examples (we did the math)
| Project | Cost basis | Total |
|---|---|---|
| 12-vent home | 12 x $25 – $50 per vent (all sources) – our math | $300 – $600 (matches all three tables) |
| 2,000 sq ft home, three ways | $0.15 – $0.40 per sq ft across sources – our math | $300 – $800 depending on pricing model |
| Dryer vent bundled vs standalone | $100 bundled vs up to $250 solo (Angi, HomeGuide) – our math | bundling saves up to $150 |
These are example projects, not quotes – home size, vent count, duct type, access and contamination set the real number.
