Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFranchise Investment Overview
So you want to know what it actually costs to open a Cardinal Air Duct Cleaning location. Fair question, and one we’d rather answer with ballpark numbers than a sales pitch. We built this brand inside Relay Home Co., which has been at this since 2005, so we know what a startup spend looks like in this trade. The figures below are marketing estimates, not a legal offering. They exist to help you decide if this is worth a real conversation. Omar Haddad, our Owner & Lead Technician, put this together the way he runs a job site: no mystery, no fine print surprises, just the straight numbers.
Estimated Startup Investment
Air duct cleaning is equipment-heavy on day one. You’re not buying a desk and a laptop. You’re buying the tools that let a two-person crew clean a 3,500-square-foot home in a single afternoon and document the whole thing. Here’s how a typical startup budget breaks down, and these ranges reflect what we see across markets in 2026.
| Expense Category | Estimated Range | What It Covers |
|---|---|---|
| Franchise Fee | $35,000 – $55,000 | Brand license, training, territory rights, launch support |
| Equipment & Vehicles | $60,000 – $95,000 | Rotobrush system, Nikro HEPA vacuum, Abatement Technologies containment unit, cargo van, safety gear |
| Initial Marketing | $12,000 – $25,000 | Local launch campaign, Google Business Profile setup, branded website, first 90 days of lead generation |
| Working Capital | $25,000 – $45,000 | First six months of payroll, rent, insurance, fuel, and day-to-day operations before revenue stabilizes |
| Total Estimated Investment | $132,000 – $220,000 | Complete startup range, before any financing |
Those are honest numbers for this trade. A single truck operation lands near the bottom of that range. A two-truck launch with a full equipment package and aggressive marketing lands near the top. You’ll get exact figures in the official documents after you qualify, but nothing on this page is designed to bait you into a cheap-looking number.
What’s Included
Your franchise fee isn’t a nameplate. It buys the operating system that makes a Cardinal location work from the first booking. Here’s what’s in it.
- Brand license and territory. You get a protected service area sized to support a full-time operation. No corporate locations competing against you three miles away.
- Hands-on training. You and your lead technician learn the full service process: rotary brush cleaning, HEPA extraction, containment setup, and the photo documentation protocol. Omar teaches this himself at Relay Home Co. headquarters.
- The Relay Standard booking system. Live trackable arrival windows, digital invoices payable by link, and before-and-after photo delivery. All built and maintained for you. This is the phone-native experience your customers will expect.
- Launch marketing package. Your territory gets a branded website, local search setup, and a 90-day campaign built around the 365-Day Done Right Promise. This is a differentiator nobody in your market will have.
- Ongoing operational support. A live person answers franchise partner calls 24/7, same as our customer line. No corporate phone trees. When a job goes sideways, you’re talking to someone who has actually run a duct cleaning crew.
- Equipment guidance and fleet standards. We tell you exactly what to buy, from which suppliers, and at what spec. Rotobrush for agitation, Nikro for HEPA extraction, Abatement Technologies for containment when we’re pulling debris out of a crawlspace. No guessing, no cheap knockoffs.
Financing & Next Steps
Most franchise partners don’t write a single check for the whole startup cost. Third-party equipment financing is common in this trade, and lenders who work with home-service franchises understand the revenue model well enough to structure terms around the van, the tools, and the initial operating float. SBA loans are another path some partners pursue, though every applicant’s situation is different. We don’t offer in-house financing, and we won’t pretend there’s a secret way to start a duct cleaning business for $20,000. There isn’t, and anyone who tells you otherwise is selling something other than a real business.
Here’s the process, plain and simple. You call the number below or request the info kit. You’ll have a conversation with a real person, not a web form. We’ll ask about your market, your timeline, and whether you want a one-truck or two-truck launch. If it looks like a fit, you’ll get the official Franchise Disclosure Document with exact figures for your territory. That document is the only place where numbers become binding. Everything on this page is a ballpark to help you decide if the range is realistic for you before you invest time in the process.
Call (737) 727-2314 or request the info kit below. A live person answers, 24/7. No phone tag, no callback loops. You’ll know who you’re talking to before the end of the first ring.
All investment figures above are non-binding marketing estimates. Actual startup costs vary by market, equipment configuration, and territory size. Official figures are provided in the Franchise Disclosure Document during the qualification process.
