Air Duct Cleaning Cost in 2026: A Transparent Price Breakdown

If your air ducts need cleaning, the first thing most homeowners want to know is simple: what is this going to cost me? As a NADCA-trained service company running hundreds of jobs a year, here is a transparent breakdown of 2026 air duct cleaning costs — what's fair, what's a red flag, and what actually drives the price.

The short answer: typical 2026 pricing

Most single-family homes pay between $450 and $950 for a full source-removal air duct cleaning with HEPA vacuum, blower and coil cleaning, and a written before-and-after report.

• Standard 1,500–2,500 sq ft home, one HVAC system: $450 – $750
• Larger 2,500–4,000 sq ft home, one or two systems: $700 – $1,200
• Two-system homes or homes with heavy contamination (mold, rodents, post-construction): $900 – $1,800
• Dryer vent cleaning (add-on or standalone): $110 – $220
• AC coil cleaning (add-on): $120 – $300
• Full mold remediation with antimicrobial fog: $600 – $2,000 depending on documentation

Per-vent pricing runs $25–$45 per register when quoted that way, but the real work is in the trunk lines, plenum, blower, and coil — not the register faces. Any quote that only counts vents is skipping most of the job.

The '$99 whole house' scam

If you have ever seen a coupon for "$99 whole-house duct cleaning", walk away. The FTC and NADCA have both published warnings about it. Here is how it always plays out:

1. The tech arrives with a small shop vac (no HEPA filtration, no negative-air machine).
2. Within 10 minutes they "discover" mold in your ducts and hand you a $1,500–$4,000 upsell quote.
3. If you decline, they blow debris around with the shop vac and leave.

Real source-removal duct cleaning requires a truck-mounted or 5,000+ CFM portable negative-air machine with HEPA filtration, rotary agitation whips sized for your duct diameter, and 2–5 hours of on-site labor for an average home. That cannot be done for $99.

What drives the actual price

• Number of supply registers and returns: more vents = more agitation and vacuuming time
• System count: every furnace/air handler adds inspection, blower, and coil work
• Duct material: flex duct cleans faster than sheet metal; fiberglass-lined duct is fragile
• Contamination level: post-construction debris, pet hair, rodent activity, or mold all add time
• Access: attic-only supply runs in a two-story home are harder than a basement trunk line
• Add-ons: dryer vent, coil cleaning, antimicrobial fog, register replacement, filter upgrade

When add-ons are worth it (and when they aren't)

Worth it: - Dryer vent cleaning if it has been over 12 months - Coil cleaning if the AC has lost noticeable capacity - Antimicrobial fog if we camera-document mold or biofilm

Skip it: - "UV lights inside your ducts" sold on the spot for $600+ — worth having, but not an emergency upsell - Duct sealing quoted before a real leakage test - "Electrostatic filters" hawked as a $400 upgrade

Should you DIY?

You can pull register covers, vacuum the first 12–18 inches of accessible duct, and swap your filter. That is worthwhile maintenance. But real cleaning requires negative-air containment, rotary agitation on the trunk lines, and coil/blower access — none of which is safe or effective with a shop vac.

Bottom line

For an average home, budget $500–$900 for a legitimate whole-system cleaning. Anything under $200 is a bait-and-switch. Anything over $1,500 without documented mold or rodent contamination deserves a second opinion.
