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
If you’re reading this, you’re probably asking the same question every serious buyer asks us: what does it actually cost to open a Linden Air Duct Cleaning territory? We believe in putting numbers on the table early, the same way we put a price in writing before any work starts in a customer’s home. The figures below are honest ballpark ranges based on our two decades in this trade, not a glossy brochure. Your market will move these numbers around. That’s normal. What won’t change is the standard behind them: Threshold Verified, the operating backbone we’ve run every Linden location on since 2004.
Estimated Startup Investment
These ranges reflect what a new owner typically commits to get a van on the road, equipment in the truck, and a team taking calls. We’ve broken them into the categories that actually matter for an air duct cleaning operation. The total range assumes you’re starting fresh with one vehicle and a two-person crew.
| Investment Category | Estimated Range |
|---|---|
| Franchise Fee | $35,000 – $55,000 |
| Equipment & Vehicles | $45,000 – $85,000 |
| Initial Marketing & Launch | $12,000 – $25,000 |
| Working Capital (first 6 months) | $30,000 – $60,000 |
| Total Estimated Investment | $122,000 – $225,000 |
A few notes on the ranges. Equipment costs swing based on whether you go with a Rotobrush package or build out a Nikro rig, and whether you buy your first van new or well-maintained used. Working capital covers payroll, insurance, and fuel before your book of recurring customers fills in. These are not scare numbers, they’re real numbers. We’d rather you see them now than after you’ve signed something.
What’s Included
The franchise fee is not a door charge. It buys you the system we’ve been tightening since the first Linden crew rolled out. Here’s what comes with it:
- Brand license and territory rights for your Linden Air Duct Cleaning location, using the name and the trust that comes with the Threshold Group family.
- Initial training that covers the technical side – how to properly clean ducts and dryer vents with Rotobrush and Nikro equipment – and the operational side, including the written-price protocol and the 365-Day Done Right Promise.
- Launch marketing support so your first customers in the territory know who you are, what you charge, and why a background-checked, photo-badged tech in a marked uniform is showing up at their door.
- Threshold Standard systems – the background-check, identity-verification, and photo-badge protocols we train every technician on, plus the customer communication templates that send a tech’s name and photo before each visit.
- Equipment guidance and vendor relationships to help you source professional-grade tools and air-quality products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman at sensible prices.
- Ongoing operational support from a team that answers when you call. Not a portal. A person.
Financing & Next Steps
Most owners do not write a single check for the full investment on day one. Third-party financing is common for the equipment and vehicle portion of a startup, and some buyers use SBA-backed loans or rollover funding vehicles they already control. We can point you toward lenders who understand service businesses and won’t look at an air duct cleaning franchise like it’s a speculative bet. It’s a steady, recurring trade. Homes need their ducts cleaned whether the economy is roaring or wobbling.
Here’s the process if you want exact numbers. First, call the line below and talk to us. We’ll ask about your market, your background, and what you’re trying to build. If it’s a fit, we send the qualification materials that include the official financial figures for your territory. That’s where the ballpark ranges on this page get replaced with line items. You review them. You ask questions. We answer. If you don’t like what you see, you walk away with no drama and nothing owed. The linden is a shade tree people plant by the house for cool, clean air. That’s the name, and that’s the job. If the investment makes sense for you, we’ll help you plant it.
Call (980) 447-2498 to speak with our franchise team, or request the info kit below. A live person answers. That’s how we’ve run the phones since 2004, and it’s how we run the franchise inquiry line too.
The investment figures on this page are non-binding marketing estimates for general planning purposes only. Actual figures vary by market and are provided in official documents after you complete the qualification process.
