Air Duct Cleaning Cost (2026): $300–$700

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.

What to ask for in duct cleaning photos

Ask the customer for a photo of the furnace or air handler with its data plate, the filter slot and current filter, two or three supply registers with the covers off, the main return grille, and the dryer vent outside. Ask how many floors and HVAC systems the home has and whether there was recent renovation, pets or any sign of pests or mold. That separates a routine clean from a contamination job, and Fast Snap Pro drafts a per-vent or per-home quote from your own rates with the inclusions listed.

Listing every inclusion is what separates an honest duct cleaning quote from a "$99 whole house" ad. The customer can drop the add-ons and still know exactly what the base clean covers.
