How Much Does It Cost to Get Air Ducts Cleaned? What Homeowners Are Paying Today

So, What’s the Real Cost for Air Duct Cleaning?

For most homeowners, the residential air duct cleaning cost ranges from $300 to $600, with national averages sitting around $400 to $500. Of course, that number can fluctuate based on where you live, how big your home is, and what kind of ductwork you’re dealing with.

Here’s a general pricing breakdown:

• Per vent pricing: $25–$50 per vent
• Per square foot: $0.15–$0.30 per sq. ft.
• Hourly rates: $90–$130 per hour
• Full-system flat rate: $300–$800 for average-sized homes

Keep in mind, these are just starting points. Add-on services and system conditions can drive your cost estimate higher—especially if complications are discovered during the job.

What Drives the Price Up or Down?

1. Home Size & Duct Layout

Larger homes with more vents and longer duct runs naturally require more labor and equipment. Cleaning a 2,000 sq. ft. home with 20 vents will cost significantly more than a 1,000 sq. ft. condo with only 8.

2. Accessibility

If your ducts are tucked behind tight crawl spaces, above high ceilings, or inside wall cavities, technicians may charge extra for the added effort it takes to reach them.

3. Type of Ductwork

Rigid metal ducts are easier (and cheaper) to clean than flexible or fiberglass-lined ones, which require special handling to avoid damage.

4. Contamination Levels

Basic dust and debris removal falls into standard pricing. But if your technician discovers rodents, mold, or construction debris, expect added charges for remediation. For example:

• Cleaning & mold removal cost: $1,000–$3,000+
• Rodent cleanup or pest control: $200–$800+
• Asbestos-laden ducts: $5–$20 per square foot for removal

5. Add-On Services

Some companies offer optional treatments like:

• Germicidal UV upgrades to help reduce airborne microbes inside the system
• Antimicrobial treatments or fogging for addressing odors, mold, or illness-related concerns
• Video inspections to verify cleaning quality
• Sealant applications to improve airflow efficiency and reduce energy loss

These can add $100–$500 or more to your bill. While not always necessary, certain homes (especially with mold, illness, or pets) may benefit from these extras.

Is Air Duct Cleaning Expensive? Or Just Misunderstood?

Some homeowners hesitate to schedule this service due to concerns about value. The reality? Cost varies based on context.

Ductwork cleaning isn’t a magic fix that instantly purifies your air or eliminates every allergen. But in specific situations—after construction, flooding, mold exposure, or years of skipped maintenance—it can noticeably reduce airborne particles and improve HVAC efficiency.

Take mold, for instance: addressing contamination inside ventilation systems isn’t just aesthetic—it’s about safety. That’s why mold removal pricing often reflects the seriousness of the issue, especially in homes with respiratory sensitivities or a history of dampness.

Can You DIY Your Ducts to Save Money?

While it’s possible to clean visible vents and accessible areas with a shop vac and brush, the average homeowner can’t reach deep into the duct system. Professional cleaners use high-powered negative pressure vacuums and agitation tools that go well beyond basic surface cleaning.

Attempting to clean ducts yourself may lead to:

• Dislodged debris that spreads instead of being removed
• Accidental damage to ductwork
• Missed microbial contamination
• Increased exposure to allergens like mold spores or rodent droppings

That said, routine vent dusting and filter changes are absolutely worth doing between professional cleanings.

Hidden Costs to Watch Out For

Low advertised prices can be misleading. Some too-good-to-be-true duct cleaning offers hook homeowners with rates like “$99 for the whole house,” only to tack on upsells later. Be cautious of companies that:

• Don’t provide a detailed estimate
• Refuse to explain what’s included
• Pressure you into immediate upgrades or treatments

If you’re seeing prices that seem too good to be true, double-check reviews and references. Reputable companies will provide a transparent cost estimate up front, with no bait-and-switch tactics.

What’s the Right Price for You?

If you’re getting multiple quotes, compare not only price, but:

• Whether mold, dust, or pest inspection is included
• How many vents are being cleaned
• What equipment is used (negative air vs. rotary brushes)
• If they’re certified (e.g., NADCA membership)
• If extra services are included or optional

Choosing a provider based solely on cost might save money upfront but could miss major issues or damage your ductwork long-term. Focus on value, not just price.

When Is Professional Cleaning Worth the Investment?

While the scientific jury is still out on how much duct cleaning improves health across the board, it’s widely considered a smart move when:

• You smell mold, mildew, or musty odors from vents
• There’s visible debris coming from registers
• You’ve recently completed dusty renovations
• You’ve experienced rodent or pest issues in the home
• Allergy or asthma symptoms seem worse indoors
• Your ducts haven’t been cleaned in over 5 years

If any of these apply, the residential cleaning cost may be well worth the air quality peace of mind.

Final Thoughts: Budget Smart, Not Cheap

The cost for air duct cleaning doesn’t have to be a mystery—or a ripoff. By understanding the pricing variables, common add-ons, and red flags to avoid, you’ll be in a much better position to choose a provider that offers both transparency and quality.

Still deciding? Compare estimates from certified professionals, ask questions about what’s included, and don’t hesitate to walk away from deals that feel too vague—or too good to be true. Quality service isn’t always the cheapest, but it should always be clear, professional, and worth the investment in your home’s air and energy health.
