Air Duct Cleaning Cost (2026)

Air duct cleaning costs $300 to $700 for an average 2,000-square-foot home in 2026, or roughly $0.15 to $0.40 per square foot. Larger homes, multiple systems, and add-ons like coil cleaning or sanitizing push toward $1,000.

Cost breakdown

• Average single-system home: $350-$550.
• Per square foot: $0.15-$0.40.
• Per vent/register pricing model: $25-$45 per vent, with a minimum.
• Second HVAC system: add $150-$300.
• Add-ons: sanitizing, coil cleaning, dryer vent: $75-$200 each.
• Heavy contamination (mold, rodents, post-renovation): $700-$1,500+.

What actually drives the price

Home size, number of vents, and number of separate HVAC systems are the base. Then: level of contamination (routine dust vs mold, construction debris, or pest activity), duct accessibility, whether the blower and coil are included, and add-ons. Be wary of quoting a flat low price sight-unseen — a badly contaminated system is a different job than a maintenance clean.

Set a clear scope so you're not the bait-and-switch guy

Duct cleaning has a reputation problem from companies that advertise $99 and upsell on site. Quote a real per-home or per-vent price with the inclusions spelled out (supply and return runs, registers, main trunk, blower, coil), and note in writing what heavy contamination would cost extra.

Scoping this job from photos

The visible factors — size, access, condition, and finish level — are usually enough for a first-pass range from a few photos and a short description of what the customer wants. A final walkthrough is still worth doing before a firm number, since what's behind walls, underground, or under a surface can't be seen in a photo. Fast Snap Pro lets a customer send photos and describe the job so you can return a realistic starting range before scheduling the on-site visit.
