How to Price a Duct Cleaning Job (and When to Walk Away)

Duct cleaning is one of the most abused categories in home services. $69 ads lure customers who end up paying $1,500 for work that was already supposed to be included. If you want to run a legitimate duct cleaning operation, here is how to price it, when to upsell, and when to walk away from the quote altogether.

What Fair Duct Cleaning Costs

A proper whole-home duct cleaning for a single-system 2,000 sq ft home with 10–12 vents runs $400–$1,000 in 2026. The variables:

• Vent count — $30–$60 per vent is a standard metric
• System count — second furnace or air handler adds $200–$400
• Containment — negative-air HEPA filtration (prevents dust redistribution during cleaning) adds $100–$200 and separates professionals from truck-mount cowboys
• Dryer vent cleaning — $75–$150 add-on, high margin
• UV sanitization or antimicrobial fogging — $100–$250 add-on, legitimate for mold or post-remediation jobs, overpriced for routine cleaning

Your Labor and Equipment Costs

A whole-home clean takes a 2-person crew 3–5 hours. That is $200–$400 in labor at $40–$50 per hour per tech. Your truck-mount vacuum ($8,000–$25,000 commercial unit) depreciates and needs filter changes. Brushes and attachments ($400–$800 kit) wear out. Containment materials (poly sheeting, negative air machine filters) are $20–$40 per job. If you are quoting below $400, you are either skipping steps or losing money.

When to Decline the Job

Walk away from these bids:

• Flex duct that is deteriorated or torn — cleaning tears damaged flex further. Quote replacement, not cleaning.
• Fiberglass ductboard with visible mold — fiberglass board absorbs biological contamination. Cleaning does not eliminate it. Quote replacement or refuse the bid.
• Severe rodent or insect infestation — contaminated insulation needs removal and reinstallation, not vacuuming. Refer to a remediation specialist and keep your name off the invoice.
• Asbestos-wrapped supply trunks — common in pre-1980 homes. Do not touch. Refer to a licensed asbestos abatement contractor.

The jobs that look like easy money and turn into health liabilities are the ones to decline on the walkthrough. Protect your reputation and your license.

When to Upsell to Sealing Instead

A customer calls for cleaning because "the house is dusty and the system is inefficient." The real problem is often duct leakage, not internal dust. A 20-minute duct leak inspection (visible checks + static pressure test) tells you whether sealing is the right scope. If the system is leaking 25%+, selling cleaning is selling the wrong fix. Sell sealing. The customer gets real results, your margin is higher, and you look like the honest contractor who did not just upsell them.

The Service Agreement Angle

Duct cleaning fits well into a 5-year HVAC service agreement — one cleaning included in year 3 or 5. Price the agreement to include cleaning as a $300–$400 value add-on. Customers see the long-term value, you lock in return business, and the cleaning doubles as a touchpoint to upsell air sealing, duct repair, or system replacement.

Build Your Quote

Use the Duct Cleaning Cost Calculator to price by vent count, system count, containment level, and add-ons. The calculator gives you a defensible number that covers your truck, crew, and consumables with margin. If a customer compares to a $69 ad, walk them through what is actually in that quote. You will win the job on scope, not price.
