One of the Top 15 Service Businesses to Start This Year
Air duct cleaning is a strong, high-margin business that addresses real health and maintenance concerns for homeowners and businesses. It’s ideal for anyone looking to start a trade with minimal equipment, steady demand, and the ability to scale. If you’re comfortable working in attics or crawlspaces and want a repeatable service that pays well, this one is worth a close look.
Ease of Entry
Starting an air duct cleaning business is relatively straightforward and doesn’t require HVAC licensing in most areas. However, certification through organizations like NADCA can add credibility and improve your marketability.
Startup costs are typically under $10,000, and many get started for less. Essentials include:
- A powerful vacuum system or negative air machine
- Rotary brush tools, hoses, and possibly a compressor
- A reliable van or SUV to transport equipment
- Optional: mold remediation certification for added services
Some entrepreneurs start small using shop vacs and duct kits, then reinvest in better tools as the business grows. Equipment rental and financing options are available from most suppliers, helping to keep the barrier to entry low.
The work itself is hands-on but not overly technical. You’ll be hooking up vacuums, brushing out ducts, adding disinfectant, and sometimes cleaning blower fans. You’ll need to be comfortable working in tight or hot spaces like attics and crawlspaces.
Profit Potential
Air duct cleaning jobs are high-ticket and offer very strong margins. A full-home service typically ranges from $400 to over $1,000+, depending on the property size and complexity.
- Operating costs are low, mainly fuel, filters, and labor
- Net profit margins for solo operators are often 30–50%
- One $400 job per day can generate ~$100,000 per year in gross revenue
- At 50% margins, that’s about $50,000 in owner profit
Small duct cleaning businesses often report annual incomes between $60,000 and $120,000, depending on job volume and region. As the business scales, with more equipment, advertising, and employees, gross revenue can grow into the high six figures, although net margins typically decline with added overhead.
This is a business where delivering consistent quality and building local trust can lead to repeat business, strong word-of-mouth, and commercial contracts.
Market Demand
The air duct cleaning industry is valued at approximately $1.1 billion in the U.S. and is projected to grow at about 4.3% annually through 2032.
Factors fueling demand include:
- Increased awareness around indoor air quality
- More Americans living with asthma, allergies, and respiratory issues
- Growth in newer HVAC-equipped homes
- Frequent cleanups after renovations or tenant turnover
- Rising demand for services that reduce dust, allergens, and mold
Ducts need to be cleaned every few years, making this a recurring service for many clients. In multi-unit properties and office buildings, clean air systems are a top maintenance priority.
Growth Trends
While the industry grew slowly from 2019 to 2024 due to pandemic disruption (just 0.7% CAGR), the outlook for the next 5 to 10 years is positive.
Key trends include:
- An uptick in home construction and HVAC installations
- Stricter indoor air quality guidelines in some states
- Fire prevention awareness for homes and commercial buildings
- Cross-selling opportunities with related services like chimney sweeping, filter changes, or furnace cleaning
- Global HVAC and duct cleaning services market projected to surpass $17 billion by 2032
Competition is rising, especially from HVAC companies and national franchise brands. Independent businesses can stand out by offering transparent pricing, fast service, and detailed before-and-after reports.
Final Thoughts
Air duct cleaning is a solid business with:
- Low to moderate startup costs
- High ticket service rates
- Minimal labor and material costs
- Strong recurring and referral potential
If you’re reliable, safety-conscious, and committed to helping customers improve their indoor air quality, this is a smart business to start in 2025 or 2026. It’s also an ideal gateway to offer related services and build a full-scale indoor air care business.
