Business Overview


Who is this business right for?

Heating, ventilation and air conditioning (HVAC) technicians are especially qualified for starting an air duct cleaning business, as they already have the technical knowledge that’s necessary to clean air ducts. Anyone who is mechanically inclined, however, can learn what they need to know about HVAC systems.

It also helps to be self-motivated, as business owners often are working by themselves when cleaning air ducts.

Finally, this is a business that can be started while working another job, as cleanings can be scheduled around other obligations. A business owner who has a traditional day job, for example, can perform cleanings during the evenings and on weekends.

What happens during a typical day at an air duct cleaning business?

A business owner of an air duct cleaning business will spend much of their day cleaning air ducts, which is hands-on work that involves running tools and brushes through the ducts of HVAC systems. When not actually cleaning ducts, business owners will spend time driving to and from customer’s locations, scheduling appointments and maintaining tools.

What is the target market?

Air duct cleaning businesses frequently clean individuals’ residential HVAC systems, but their ideal customers are businesses. Cleaning systems in commercial buildings takes longer, so air duct cleaning business owners can charge more. Additionally, businesses that own commercial buildings frequently can afford to pay more than individual residents for air duct cleanings.

How does an air duct cleaning business make money?

An air duct cleaning business makes money by charging customers to clean their HVAC systems’ air ducts. Most businesses charge a set price per cleaning rather than an hourly rate.

What is the growth potential for an air duct cleaning business?

An air duct cleaning business may be a one-person operation that serves a single city or town, or it can be a large company that has many locations. AirDuct Clean, for example, is a regional company with franchises throughout Michigan. Ductz is a national company with franchises in many states.

According to a 2005 EPA report, the air duct cleaning industry’s annual revenue from air duct cleanings was $4 billion, and “building remediation for indoor air quality” brought in another $3.4 billion annually. Since this report was released, these numbers have likely increased.

Getting Started


What are some skills and experiences that will help you build a successful air duct cleaning business?

An air duct cleaning business owner must have an in-depth knowledge of HVAC systems. Those who don’t have experience in this field can take online and classroom courses through the National Air Duct Cleaners Association (NADCA). The NADCA also offers two certifications for air duct cleaners: an air systems cleaning specialist (ACSC) certification and a certified ventilation inspector (CVI) certification.

What are the costs involved in opening an air duct cleaning business?

Starting a residential air duct cleaning business costs about $5,600, and a commercial air duct cleaning business costs about $10,000 to open. Most of these costs go towards equipment that is needed to clean air ducts, which includes a vacuum collection system, agitation and cleaning tools, an air compressor, a wet/dry vacuum with HEPA filtration and duct accessing tools. Business owners also need sanitizer, coil cleaner, personal safety equipment and miscellaneous tools (e.g. a ladder and hand tools), but these cost less than the other equipment.

The above figures don’t include a vehicle, which is also necessary. Business owners either need a trailer to tow their equipment in or a truck that can fit everything. Most business owners, however, keep their startup costs low by using a vehicle or trailer they already have.

What are the steps to start an air duct cleaning business?

Once you're ready to start your air duct cleaning business, follow these steps to ensure that your business is legally compliant and avoid wasting time and money as your business grows:

  1. Plan your business. A clear plan is essential for success as an entrepreneur. A few important topics to consider are your initial costs, your target market, and how long it will take you to break even.
  2. Form a legal entity. Establishing a legal business entity prevents you from being personally liable if your air duct cleaning business is sued.
  3. Register for taxes. You will need to register for a variety of state and federal taxes before you can open for business.
  4. Open a business bank account. A dedicated checking account for your air duct cleaning business keeps your finances organized and makes your business appear more professional to your customers.
  5. Set up business accounting. Recording your various expenses and sources of income is critical to understanding the financial performance of your business. Keeping accurate and detailed accounts also greatly simplifies your annual tax filing.
  6. Obtain necessary permits and licenses. Failure to acquire necessary permits and licenses can result in hefty fines, or even cause your business to be shut down.
  7. Get business insurance. Insurance is highly recommended for all business owners. If you hire employees, workers compensation insurance may be a legal requirement in your state.
  8. Define your brand. Your brand is what your company stands for, as well as how your business is perceived by the public. A strong brand will help your business stand out from competitors.
  9. Establish a web presence. A business website allows customers to learn more about your company and the products or services you offer. You can also use social media to attract new clients or customers.

Growing Your Business


How to promote & market an air duct cleaning business

Since most air duct cleaning businesses, at least when they’re first starting out, serve a relatively small geographic area, ads in local outlets can be effective marketing tools. Radio stations, newspapers and even local deal books can be good places to purchase ads.

How to keep customers coming back

Air duct cleaning businesses can distinguish themselves by simply being courteous to customers. Showing up on time, wearing booties indoors and cleaning up after a job is finished will set a business apart from many others.

How and when to build a team

Business owners don’t have to hire employees, but some decide to hire one employee fairly early on because having two people to work on cleanings can make jobs go much faster. Business owners that want to grow their company often hire more employees once they’re fully booked every week.

Legal Considerations


State & Local Business Licensing Requirements

Most states require air duct cleaners to have a mechanical contractor license. To obtain such a license, applicants must have either relevant education (typically a bachelor’s degree) or experience in the industry. This will qualify them to take the Mechanical Contractor License Exam, which they must pass. Learn more about licensing requirements in your state by visiting SBA’s reference to state licenses and permits.

Most businesses are required to collect sales tax on the goods or services they provide. To learn more about how sales tax will affect your business, check out our informative guide, Sales Tax for Small Businesses.

In addition, certain local licensing or regulatory requirements may apply. For more information about local licenses and permits:

Service Agreement

Air duct cleaning businesses should consider requiring clients to sign a service agreement before starting a new project. This agreement should clarify client expectations and minimize risk of legal disputes by setting out payment terms and conditions, service level expectations, and intellectual property ownership. Here is an example service agreement.

Earning Potential


How much can you charge customers?

Most air duct cleanings cost between $300 and $500. On average, businesses charge $35 per vent cleaned. Cleaning the HVAC system in a house that has 12 vents, for example, would cost $410 ($35 x 12 vents).

What are the ongoing expenses for an air duct cleaning business?

The ongoing expenses for air duct cleaning businesses are fairly minimal. They include expenses for fuel to get to and from customers’ sites, maintenance for the business’ trailer or truck, and supplies, like sanitizer and coil cleaner.

How much profit can an air duct cleaning business make?

A typical air duct cleaning takes about three hours, so business owners can often complete two cleanings a day. At this rate, a fully booked business could bring in revenue between $3,000 and $5,000 each week. Even after taking out an employee’s wages, advertising costs and ongoing expenses, the business owner could be left with a decent profit.

How can you make your business more profitable?

An air duct cleaning business can increase its revenue by either offering additional HVAC services or partnering with a local business that does. An HVAC company in the area may be willing to pay a commission for any work that’s referred to them.
