A few minutes of read-only financials and a handful of questions surfaces what a buyer would discount your duct-cleaning business for — how much of the selling and lead generation only you do, how much of the book is one-time residential versus recurring commercial, and the truck-mounted-vacuum replacement bill they will subtract from cash flow. Preview is free; $499 for the full memo.
Enter two numbers for an instant Air Duct Cleaning ballpark. No signup — the real number comes from your books.
We answer each one from your books first — so you fix the story before a diligence team writes the number.
In most duct-cleaning shops the owner converts the inbound quotes, holds the commercial accounts, and runs the lead generation personally. A buyer treats that as buying your phone and your contacts rather than a transferable business — if the selling and the lead flow leave with you, bookings can fall off a cliff. Owner-as-only-salesperson is the single hardest thing to hand off, and it pulls the price toward the floor.
When most jobs come from a single paid platform or one referral source, the top line lives at the mercy of that channel's pricing and ranking. A buyer prices the risk that the channel's cost climbs or its volume dries up, and underwrites the downside rather than your current pace. Single-lead-source dependence is a concentration risk every bit as real as one big customer.
A book of one-and-done residential cleans has to be re-won customer by customer every single month, so a buyer credits little of it as durable. The recurring engine a buyer pays up for — standing commercial facility contracts, scheduled repeat-residential, indoor-air-quality programs — is exactly what an undifferentiated residential shop tends to lack, and its absence caps the multiple.
Anyone with a van and a portable machine can undercut you on a residential duct clean, so a buyer worries about commoditization and a race to the bottom on price. Without certification, an indoor-air-quality and add-on story, and recurring commercial work to differentiate, the business reads as a low-margin, easily-replicated operation — and that perception lands directly on the multiple.
Each lever is sized for a typical $1.5m–$3m revenue air-duct & hvac-system cleaning company, residential + commercial-contract mix — about $300K EBITDA. Same number whether we frame it as “what a buyer discounts” or “what you keep by fixing it.”
Put property-manager, healthcare, school, and restaurant accounts on standing facility-cleaning contracts, rebook residential customers on a scheduled cycle, and attach indoor-air-quality, dryer-vent, and coil add-ons to every job. Converting one-time work into a renewable book is the single biggest lever — it smooths the lead-dependent residential swings and is what a buyer credits as durable.
adds about 0.4–0.7× to your multiple · usually takes 12–24 months
Move the selling and the commercial relationships onto a non-owner manager, and turn the marketing — local search, reviews, paid channels — into a documented system in a CRM rather than something that runs through your phone. Diversifying away from a single lead source and proving the business books work without you is what lifts it from 'buying the owner' toward 'buying a company.'
adds about 0.3–0.6× to your multiple · usually takes 12–24 months
Segment revenue so the recurring mix is visible, break out customer-acquisition cost by channel, carry NADCA / ASCS certification on a non-owner crew lead, and keep a documented truck-mounted-vacuum and van schedule. Clean records and a credentialed, well-equipped crew let a buyer underwrite the business confidently and protect the price from a mid-diligence re-trade.
adds about 0.1–0.3× to your multiple · usually takes 3–6 months
Typical impact ranges blended from lower-middle-market transaction data, sub-$50M M&A databases, and observed consolidator pricing in the $300K–$3M EBITDA band. Directional, not a guarantee — your memo computes your actual numbers from your books.

Air duct cleaning is a fragmented, low-barrier service trade, and the buyer pool reflects that. Owner-operated, residential-weighted shops sell mostly to individual and SBA-backed buyers acquiring a job they intend to grow. As a book tilts toward recurring commercial contracts, certified crews, and a manager-run sales function, it begins to attract building-services consolidators and private-equity platforms rolling up facility and indoor-air-quality services, alongside national service brands such as Stanley Steemer, DUCTZ, and COIT. The platforms pay up for recurring commercial revenue, diversified lead channels, NADCA-certified capability, and an owner-independent organization.

Most Air Duct Cleaning businesses in the $1M–$10M revenue range trade at roughly 2.8× to 4.5× normalized EBITDA, with a typical deal near 3.6×. Smaller, owner-dependent shops sit at the low end; larger, manager-run businesses with recurring revenue reach the top. Your actual number depends on your books — that's what the diagnostic computes, blending recent lower-middle-market closings, main-street marketplace sales, and academic M&A survey data.
A duct-cleaning valuation starts where a buyer's diligence team starts: your reported earnings as the baseline. From there come the normalizing adjustments — owner pay above market, personal vehicles, family wages, one-time equipment purchases — each tied to a specific transaction in your books, producing your normalized earnings. Against that we apply a multiple grounded in recent building- and cleaning-services small-business sale transactions, the closest published proxy for the trade. What moves it up or down: how much of the selling and lead generation only you can do, how concentrated your lead sources are, the recurring-versus-one-time-residential mix, the truck-mounted-vacuum and van capex a buyer will normalize, and whether certified crews transfer. Every figure traces back to your own numbers.
A recurring book of commercial facility-cleaning contracts and scheduled repeat-residential work, an indoor-air-quality and dryer-vent add-on attach, diversified lead channels instead of one paid source, NADCA / ASCS certification held beyond the owner, a non-owner manager who runs the selling and the commercial accounts, a documented truck-mounted-vacuum and van fleet, and clean, segmented books. The diagnostic scores where you sit on each and shows what moving up would be worth.
