The numbers side by side
Duct and dryer vent franchises sell a brand, a truck setup and a marketing system for a service homeowners rarely think about until the dryer stops drying. Going solo starts with a portable machine and a dryer vent kit.
| Up-front fee | Total start-up | Share of sales (royalty) | Marketing or ad fee | Software or tech fee | Card processing | Term | Cash asked for | |
|---|---|---|---|---|---|---|---|---|
| Ductz | $49,900 to $74,900 | $163,654 to $224,764 | 10% | Up to 1% | $45 a week | Not in the summary; your processor's rate | 5 years | $50,000 |
| Dryer Vent Wizard | $49,900 | $84,900 to $163,400 | 10% | 2% to 4% | $251 a month and up | Not in the summary; your processor's rate | 10 years | $50,000 |
| Going solo on Koira's Office plan | $0, no franchise fee | Your own vehicle and kit; see the tools list | 0%, you keep every sale | None required; you set your own budget | $0 on the Office plan | 2.9% + 30¢ (Stripe) plus 2% (Koira) on card payments only | None; month to month | None asked |
Franchise figures are from each brand's listing in Entrepreneur's franchise directory, which summarizes the brand's Franchise Disclosure Document. Where a fee is a range, the disclosure document sets which end applies to you. Koira's figures are from koira.ai/pricing.
What the ongoing fees take
The up-front fee is paid once. The share of sales is paid on every job for the length of the agreement, before you pay yourself. Here is the arithmetic on an example year of $300,000 in sales, using the low end of each published rate:
| Brand | Royalty | Marketing or ad fee | Software or tech fee | Fees for the year |
|---|---|---|---|---|
| Ductz | $30,000 | $0 | $2,340 | $32,340 |
| Dryer Vent Wizard | $30,000 | $6,000 | $3,012 | $39,012 |
| Going solo on Koira's Office plan | $0 | Your choice | $0 | $0, plus $6,000 if every sale were paid by card |
Ductz's tech fee is $45 a week, about $195 a month; Dryer Vent Wizard's tech fee is $251 a month. Card processing is left out of the franchise rows because the summaries do not set it; you would pay a processor either way. On Koira's Office plan, Koira keeps 2% of card payments on top of Stripe's processing, and nothing on cash or check.
The example sales figure is an example, not a promise of what either path earns. Use the calculator above with your own numbers.
What the fees buy
Ductz has been franchising since 2003 and asks for $50,000 in cash and a $200,000 net worth. Dryer Vent Wizard has franchised since 2006 and asks for $50,000 in cash and a $200,000 net worth. For that, a franchise sells a known name, a written system, training and a territory.
A duct cleaning franchise fits an owner who wants a truck-mounted setup, training and a brand from day one, and plans to run several vans. It fits less well for a solo tech, because a 10% royalty comes off every dryer vent, the shortest and cheapest job in the trade.
Going solo in duct cleaning
A solo duct cleaner can start with dryer vents, a brush kit and a camera, then add a portable negative air machine for ducts. The work is getting found, showing the customer what came out, and booking the next visit before you leave.
See the duct cleaning tools list, the duct and dryer vent price list and duct and dryer vent maintenance plans.
Koira's free Office plan covers the office side a franchise system would: a website that books jobs, estimates with signing and deposits, invoices and card payments and your day plan. Paid plans add the phone and crew tools.
Before you sign anything
Federal rules require the franchisor to give you its disclosure document at least 14 calendar days before you sign or pay. Read the fee items and any sales claims with their footnotes, and call former duct cleaning owners. Our handyman franchise guide walks through the document item by item.
