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.

AfterHow Much Does Air Duct Cleaning Cost in Nashville-Davidson?
Air Duct Cleaning in Nashville-Davidson costs $350 to $700 for most homes, with the typical single-system house landing near $475. That figure buys a full negative-air setup, rotary brush agitation of every accessible trunk and branch line, and a written price agreed before anyone opens a panel. Smaller condos and single-return homes fall closer to $300, while larger two-story homes in Green Hills or Forest Hills with multiple HVAC systems run $800 to $1,400.
We put those numbers in writing before the truck pulls up. No technician at your door with a revised total, no add-ons you didn’t ask for. Just the price we quoted, the work we described, and the 365-Day Done Right Promise standing behind it.
Air Duct Cleaning Cost Breakdown (2026)
Here’s what Nashville-Davidson homeowners actually pay, line by line. These are ranges from real jobs across Davidson County, not national averages pulled off a marketing site.
| Service | Typical 2026 Range | What It Covers |
|---|---|---|
| Single-system duct cleaning (1 – 2 story home) | $350 – $700 | Up to 10 vents, one HVAC system, full negative-air and rotary brush |
| Two-system duct cleaning | $650 – $1,100 | Up to 20 vents, both systems, all accessible trunk and branch lines |
| Extra vent or register | $20 – $35 each | Beyond the standard count for your system size |
| Dryer vent cleaning | $125 – $225 | Full lint removal from vent, transition, and exterior termination |
| Duct sealing (per system) | $400 – $900 | Mastic and mesh sealing of accessible leaks on trunk and branch runs |
| Return-side deep clean (heavy buildup) | $100 – $250 add-on | Extra passes where returns carry pet hair, construction dust, or mold |
| Filter replacement during service | $25 – $80 | Standard and upgraded filters (Honeywell, Aprilaire MERV-rated options) |
| Second visit if the first wasn’t right | $0 | Covered by the 365-Day Done Right Promise; we come back at no charge |
What Drives the Number Up or Down
The single biggest factor is system count. A one-system ranch in Donelson and a two-system home in Belle Meade are two entirely different jobs. Vent count matters next: a house with 24 registers takes roughly double the agitation passes of one with 12. Buildup is the third lever. A 15-year-old home that’s never had ducts cleaned carries dust load a newer East Nashville build doesn’t, and heavy debris means more time on the negative-air machine and more passes with the rotary brush.
Access is the fourth. Crawl spaces and attics in older Nashville neighborhoods slow crews down and occasionally require a second technician. When that’s the case, it’s priced in before we start, never added mid-job.
What Affects Air Duct Cleaning Pricing in Nashville-Davidson
- Number of HVAC systems. Most single-family homes in Davidson County run one system; larger homes in Green Hills, Forest Hills, and parts of Belle Meade run two or three. Each system adds its own trunk lines and its own outlet count.
- Vent and register count. Standard pricing covers roughly 10 vents per system. Beyond that, expect $20 to $35 each. A 4,000-square-foot home can easily carry 22 registers.
- Duct material and layout. Flexible flex-duct cleans differently than rigid sheet metal. Older Nashville homes in 12South and Germantown often have a mix of both, and each type needs a different brush head and agitation speed.
- Dust and debris load. Middle Tennessee’s humid spring and fall pollen season pushes more particulate through return systems. Homes near the Cumberland River bottoms or with heavy tree cover around them tend to accumulate debris faster than hilltop properties.
- Access and crawl space conditions. Attic runs and low-clearance crawl spaces add time. So does anything requiring a ladder setup inside the home to reach ceiling registers above 10 feet.
- Add-on services. Dryer vent cleaning, duct sealing, and filter replacement are each priced separately and each has its own value. Ducts leaking 20% of conditioned air waste more than a dirty duct costs to clean, and sealing typically pays for itself within a couple of cooling seasons in Nashville’s summer heat.
How to Save on Air Duct Cleaning in Nashville-Davidson
You don’t need the most expensive package. You need the right work for your home. A few practical ways to keep the number down without cutting corners:
- Bundle dryer vent cleaning with duct cleaning. Same trip, same crew, less setup time, less cost to you. Many Hollis customers in Nashville-Davidson save $50 to $75 by pairing the two.
- Clean ducts and seal leaks in the same visit. If a technician is already on site with the negative-air machine running, adding duct sealing costs less than booking it as a separate job. This is the single highest-return add-on for Nashville homes.
- Ask for a written price before booking. Get the number in writing before any work starts. If a company can’t put it in writing, that’s a signal.
- Don’t pay for upgrades you don’t need. A home with light dust and no pets rarely needs the return-side deep clean. Ask what’s actually on your floors and in your returns before agreeing to extras.
- Time it after pollen season. Late spring and early summer in Davidson County are heavy pollen months. Scheduling in early fall means the work lasts longer before the next round of buildup.
We quote every job free, and we quote it in writing. Call (361) 326-5060 and we’ll give you a real number for your address, not a range that jumps once we’re standing in your hallway.
Why Written Pricing Matters in This Market
Nashville’s HVAC and duct cleaning market has no shortage of $99 teaser offers that become $600 once the crew is inside. We watch homeowners get told their ducts have “toxic mold” or “dangerous debris” that wasn’t visible from the driveway. Every Hollis job starts with a written price and ends with a written price. The number doesn’t move because our equipment found something they already knew about.
How Is Air Duct Cleaning Actually Done?
Understanding the process helps you spot a cheap job from a real one. Hollis crews use the same professional-grade equipment that commercial buildings hire us for: Rotobrush rotary brush systems to agitate dust off duct walls, Nikro negative-air machines to pull that dust out and trap it in HEPA filtration instead of pushing it into your living room, and Abatement Technologies containment equipment when the job calls for it.
Here’s the sequence on a typical Nashville-Davidson home:
- Written price agreed and signed. Before any equipment comes off the truck.
- Negative-air setup at the main trunk. A hose connects the machine to your system, creating constant suction so loosened debris never redistributes into rooms.
- Rotary brush agitation. A rotating brush travels each trunk and branch line, physically scrubbing dust off duct walls and out to the machine.
- Register and return cleaning. Every supply and return is cleaned and, where applicable, wiped down. Vents get brushed and vacuumed.
- Filter check and recommendation. We tell you what your current filter is doing and whether an upgrade to a Honeywell or Aprilaire MERV-rated filter makes sense for your system.
- Site cleanup. Drop cloths up, drop cloths down, work area left cleaner than we found it.
Skip any one of those steps and you’re not getting duct cleaning. You’re getting a vacuum waved at your registers.
When Duct Sealing Is Worth the Extra
Nashville summer heat pushes HVAC systems hard. If your ducts are leaking 15 to 25% of conditioned air into the attic or crawl space (which older Davidson County homes often are), you’re paying to cool the attic. Duct sealing with mastic and mesh closes those leaks and typically runs $400 to $900 per system. The savings show up in your energy bill within the first summer.
FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in Nashville-Davidson, TN?
Most Nashville-Davidson homes pay $350 to $700 for single-system cleaning and $650 to $1,100 for homes with two systems. That range covers full negative-air setup, rotary brush agitation, and every accessible vent. Homes over 3,500 square feet or with heavy pet debris often land closer to $900. Call (361) 326-5060 for a written price on your specific address.
Is duct cleaning worth it in Nashville?
Yes, in homes older than 8 to 10 years or with pets. Middle Tennessee’s pollen season pushes fine particulate through HVAC systems more than drier climates, and Nashville homes with crawl-space duct runs draw additional dust from below. If your ducts have never been cleaned and the home was built before 2015, the buildup is real. The work is worth it when it’s done by the book, not when someone spends 20 minutes with a shop vac. Call (361) 326-5060 for our plain-answer recommendation on your home.
Is it cheaper to repair or replace ducts?
Repair, in almost every case. Duct cleaning runs $350 to $700; duct sealing runs $400 to $900 per system. Full duct replacement typically costs $3,000 to $8,000 and is only necessary when the ductwork is crushed, disconnected, or contaminated beyond sealing. If a company tells you your ducts need replacing after a 30-minute inspection, get a second written opinion. Call (361) 326-5060 and we’ll give you our honest read, even if the answer is “you don’t need us yet.”
How long does air duct cleaning take?
Two to four hours for a single-system home, four to six for two-system homes. The variable is access: attic and crawl-space runs in older Nashville neighborhoods take longer than slab-level ductwork. We give you a window when you book and we arrive inside it. Call (361) 326-5060 to schedule.
Can you clean ducts the same day in Nashville-Davidson?
Often, yes. Same-day slots depend on route and system count. Call (361) 326-5060 and a live person answers 24 hours a day, 7 days a week, no voicemail loop. We’ll tell you honestly whether we can be there today or tomorrow morning.
Does the Hollis 365-Day Done Right Promise cover duct cleaning?
Every Hollis job is covered for 365 days in writing. If your ducts accumulate visible debris or the work fails in any way within a year, we come back at no charge. That’s a free second visit, not a negotiation. Call (361) 326-5060 if you’re not sure whether a prior job qualifies; we’ll tell you straight.
Why do some Nashville duct cleaning quotes come in at $99?
Because they’re not full-service duct cleaning. A $99 quote typically covers one vent, one pass with a shop vacuum, or nothing beyond a pitch for upsells. Real duct cleaning in Nashville-Davidson runs $350 to $700 for the standard sequence described above: negative air, rotary brush, every register, and cleanup. If a price looks too low, the scope got cut. Call (361) 326-5060 and we’ll show you what the $99 quote is missing.
Why Nashville-Davidson Homeowners Call Hollis
Hollis Air Duct Cleaning has been in business since 2004 as part of the Garrison Partners family. We run independently in every market we serve, and each location follows The Garrison Standard: written prices, written guarantees, uniformed technicians, and a clean site at the end. Owner Roy Castellanos built this operation on the idea that a homeowner shouldn’t have to wonder whether the person at the door is who they say they are. That’s why every technician is background-checked and in uniform, and why every call is answered by a live person, 24/7.
The equipment we run is the same list commercial buildings hire us for: Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. Nothing is rented from a hardware store the morning of the job. Our duct sealing uses mastic and mesh, not tape, and our dryer vent cleaning reaches the exterior termination every time.
If you’ve been burned before by a no-show, a price that changed at the door, or a crew that left dust on your baseboards, that’s the reason we put pricing in writing before we start. It’s also the reason we back every job with the 365-Day Done Right Promise. If it’s not done right, we come back and make it right, at no charge.
