To start a duct cleaning business, register the company, confirm what your state and city require, buy insured, working equipment, and land your first paying jobs through a small, tracked local test before you commit to a big marketing spend.
That sentence hides the part that trips people up: the paperwork and the truck are the easy half. The harder half is knowing who will pay you, how they will find you, and what each job has to earn. This page walks through both halves in the order you will meet them.
Settle the legal footing before you buy a vacuum
Duct cleaning is rarely regulated the way electrical work is, but that varies by state and sometimes by county. Check whether your state wants a contractor or home-improvement license, whether your city wants a business permit, and what your insurer will ask before it writes a policy. Form an LLC or whatever structure your accountant recommends, open a separate business bank account, and get general liability coverage. Many homeowners and property managers will ask for a certificate of insurance before they let you in the door.
Industry training and certification, such as through NADCA, is optional in most places. It is still worth a look. It teaches you proper methods and gives you a credential to point to in a trade where customers cannot see what you did inside their walls.
Equipment, and the jobs it limits you to
Your gear decides what you can sell. A truck-mounted or powerful portable negative-air system, agitation tools, a camera for before-and-after proof, and a way to seal registers are the core of a residential setup. Commercial buildings and larger systems need more. Buy for the work you can realistically win in your first season, and look at used or leased equipment so you are not carrying heavy payments before the phone rings.
Price from your costs, not from a competitor's flyer
List what a typical job costs you: labor, fuel, disposal, supplies, insurance, equipment wear and the time spent driving and quoting. Then decide the minimum you will accept per job and per hour. Also decide how you will price add-ons such as dryer vents or sanitizing, and how you handle homes with unusually large or damaged systems. A firm price list keeps you from underquoting in your eagerness to get started.
How much demand is there, really?
Searches for this exact startup question are tiny. The whole cluster, which merges 5 different phrasings, adds up to about 50 searches a month. Over the last 12 months the range ran from 10 a month in 2026-05 to 90 a month in 2026-06. That is a small pool of people thinking about the same move you are, and it tells you little about customers.
Customer demand is a different search: people typing a service plus their town. Check that locally yourself, because it varies a lot between a dense metro and a small county. Also remember that duct cleaning is often an add-on sale, so some of your best leads may never search for it at all. They come from HVAC companies, home inspectors, realtors, remodelers and landlords.
Where your first customers will come from
| Source | Effort | What to watch |
|---|---|---|
| Google Business Profile and reviews | Low cost, steady work | Accurate service area, real photos, a review request after every job |
| Referral partners (HVAC, realtors, property managers) | Relationship time | They hand you jobs only if you show up on time and report back |
| Local search ads | Money, plus setup care | Cost per booked job, not per click |
| Neighborhood and social posts | Low cost | Mostly awareness; tie each post to a booking link |
Start with the first two rows. They cost the least and build the trust that makes any later ad work better. For more on repeat-driven local service marketing, see our guide to [marketing for cleaning business](/guides/marketing-for-cleaning-business).
If you decide to pay for clicks
The highest top-of-page bid advertisers pay in this space is $7.48. Treat that as a ceiling signal, not what you will pay on average. It does tell you that a single click is not free, and that a handful of wasted clicks adds up on a small budget. Set a daily cap, limit the ads to your actual service area, and exclude searches from people looking for jobs or DIY instructions.
Before spending, work out what a booked job is worth to you after costs and how many calls turn into jobs. That tells you how much you can afford per lead. Local Services Ads can be a good fit for trades like this; our walkthrough on [setting up Google Local Services Ads](/guides/how-to-set-up-google-local-services-ads) covers the verification steps.
Track calls, or you are guessing
Most duct cleaning leads arrive by phone. If your ads or website do not record calls and form submissions as conversions, you will not know which spend produced work. Set up call tracking and conversion tracking on day one, and ask each caller how they found you as a cross-check.
Where a second pair of hands helps, and where it does not
You can do the licensing, the equipment and the profile setup yourself. An outside team earns its fee in narrower places: building a [Google Ads](/services/google-ads) campaign that stays inside your service area, or running a [conversion tracking audit](/services/conversion-tracking-audit) so you can see which calls became jobs. If your budget is small or you have not completed a handful of jobs yet, doing it yourself and keeping notes is a reasonable choice.
A sensible order for the next few weeks
Confirm the legal requirements and get insured. Buy or lease only the equipment your first target jobs need. Set up your Business Profile with real photos, and tell a few referral partners you are open. Complete some jobs, collect reviews and photos, and record what each job cost and earned. Only then decide whether paid clicks, and whether outside help, make sense.
