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 Miami?
Air duct cleaning in Miami typically runs $350 to $700 for an average single-family home with one air handler and up to 10 vents. Larger homes with two systems, heavy mold or moisture damage, or hard-to-reach attic runs often land between $800 and $1,500. A basic single-system condo usually comes in at the lower end, around $300 to $450.
Those numbers reflect what Miami homeowners actually pay in 2026, not a national average pulled from a lead-generation site. This city is its own market. Salt air, year-round humidity, and a cooling season that never really ends put different demands on ductwork than you’d see in Phoenix or Denver. A price that looks reasonable in another state can be too low to cover the work your system actually needs here.
Before we go further, the short version: you should never hear a final price for the first time while a technician is standing in your hallway. Hollis Air Duct Cleaning writes the price down before any work starts, and it doesn’t move at the door. That’s part of The Garrison Standard, and it’s the single biggest reason homeowners call us after getting burned by a teaser rate from someone else.
Air Duct Cleaning Cost Breakdown (2026)
Here’s how pricing shakes out across the most common jobs we see in Miami. These are ranges, not quotes, but they’re grounded in real local work rather than a call-center script.
| Service | Typical Price Range | Notes |
|---|---|---|
| Single-system home, up to 10 vents | $350 – $550 | Standard condo or small house, one air handler |
| Single-system home, 11 – 15 vents | $500 – $700 | Most 3-bedroom Miami-Dade houses |
| Two-system home (dual AC) | $800 – $1,200 | Common in two-story Coral Gables and Pinecrest homes |
| Heavy contamination or mold remediation | $1,200 – $1,500+ | Post-flood, post-renovation, or long-neglected systems |
| Dryer vent cleaning (add-on) | $125 – $200 | Often bundled at a lower rate |
| Duct sealing (add-on) | $400 – $900 | Priced by linear feet and accessibility |
| Sanitizing / antimicrobial treatment | $100 – $250 | Optional, added after cleaning |
What pushes a job to the top of a range? Access and contamination, mostly. A single-story Kendall home with a clean return plenum and easy attic access is a straightforward job. A 1970s Miami Beach house with original galvanized ductwork buried behind drywall, a musty smell in the second bedroom, and a system that hasn’t been touched in a decade is a different day of work entirely. Both are legitimate; they just aren’t the same price.
What keeps a job at the bottom? Fewer vents, one system, easy access, and no visible moisture problem. If you’ve had your ducts cleaned in the last three years and just want a maintenance pass, that’s also a lower-cost visit. We’ll tell you honestly if you don’t need the full service.
What Affects Air Duct Cleaning Pricing in Miami
Six things move the number more than anything else. If you understand these, you’ll understand why two quotes for the “same” house can differ by several hundred dollars.
- Number of systems and vents. Most Miami homes run one air handler, but two-story homes in Pinecrest, Coral Gables, and parts of Palmetto Bay often run two. Each system means a separate cleaning cycle, separate equipment setup, and roughly a 40% jump in price. Count your vents before you call; it’s the fastest way to get an accurate estimate.
- Access to the ductwork. A slab-on-grade home with attic ducts is easier to reach than a home with ducts running through a low crawlspace or behind finished ceilings. Limited access means more time, more care, and sometimes a small access panel cut. That’s labor, and labor is most of your bill.
- Contamination level. Miami’s humidity is the real driver here. We routinely see microbial growth in ducts near the coast, especially in homes that run the AC hard but rarely change filters. If a system has visible mold, standing debris, or rodent evidence, it needs a negative-air setup and more time. Lighting up a flashlight and looking at your return vent will tell you a lot.
- Duct material and age. Flexible duct (common in newer construction) cleans differently than rigid galvanized metal. Older homes with original metal ducts may have loose joints or deteriorated insulation that need attention before or during cleaning. That’s a scope decision, not an upsell.
- Coastal versus inland location. Homes within a few miles of Biscayne Bay or the Atlantic deal with salt-laden air and higher ambient moisture. That tends to accelerate corrosion on metal components and encourage growth inside ductwork. It doesn’t automatically raise the price, but it often means the job is more involved than the homeowner expected.
- Add-on services. Duct sealing, sanitizing, and dryer vent cleaning are priced separately but bundled at a discount. Sealing is worth considering in Miami specifically because leaky ducts in a humid climate pull unconditioned attic air into the system, which is exactly how moisture problems start.
What Does the Price Actually Cover?
A fair air duct cleaning price in Miami covers more than a guy with a shop vac and a hose. Here’s what should be included in any quote you accept.
- Negative-air setup. A machine pulls the whole system into negative pressure so loosened debris travels out, not into your living room. Our crews use Nikro and Abatement Technologies negative-air machines. If a company doesn’t mention this step, ask about it.
- Rotary brush agitation. A Rotobrush rotary brush system spins through the ductwork and scrubs the walls. Air alone doesn’t remove caked-on buildup. The brush does.
- Supply and return cleaning. Both sides. Every register, every return, the trunk lines, and the air handler cabinet. Some low-priced outfits clean only the returns and call it done.
- Filter and coil inspection. Not a full coil cleaning necessarily, but a look. If your evaporator coil is fouled, cleaning the ducts without addressing it is wasted money.
- Site cleanup. Floors covered, equipment contained, everything put back. The Garrison Code requires the site be left clean. If a crew leaves dust on your furniture, that’s not a discount, that’s a problem.
When you compare a $199 special against a $500 quote, you’re usually comparing two different scopes of work. Sometimes the cheap one is honest and your home is simple. Often it isn’t. Ask what equipment is used, how many vents are included, and whether the price is written before work starts. Those three questions separate the real bidders from the rest.
How to Save on Air Duct Cleaning in Miami
You don’t have to pay full freight every time. A few practical moves bring the number down without cutting corners.
- Bundle services. If you need duct cleaning and dryer vent cleaning, do them on the same visit. Combined pricing is always lower than two separate trips.
- Get the free estimate in writing. This protects you more than any coupon. Hollis provides a written price before any work begins, so you can compare apples to apples. Call (361) 326-5060 and we’ll walk you through it.
- Time it right. Spring, before the heavy cooling season ramps up, is often easier to schedule than the dead of August. We don’t run artificial scarcity or countdown offers, but earlier scheduling does mean more flexibility on your end.
- Keep up with filters. A $15 filter changed on schedule saves you from a much larger cleaning bill later. This is the cheapest maintenance you’ll ever do for your system.
- Don’t skip the maintenance pass. A lighter cleaning every few years costs less than a full remediation after mold takes hold. Homeowners in Miami who stay ahead of it rarely see the top of the price range.
- Ask about the guarantee. Every Hollis job is covered by the 365-Day Done Right Promise. If the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s written into the job, not negotiated afterward.
Why Miami Pricing Isn’t the Same as Anywhere Else
You’ll find national articles quoting $250 to $400 for air duct cleaning. Those numbers are often a decade old or pulled from a low-cost market. Miami is not that market.
Here’s what makes it different. Our cooling season runs nearly year-round, so air handlers and ductwork see more runtime than in most of the country. Humidity sits high for months, which means any moisture that gets into a duct system stays there, and that’s where growth starts. Coastal salt air accelerates wear on metal components. And a large share of Miami housing stock is older, with ductwork that’s been added to, patched, and remodeled over decades. All of that adds time and care to the job.
In Natomas and similar inland neighborhoods-unlike How Much Does Air Duct Cleaning Cost in Oakland, CA? (2026 Price Guide) might cover-we’d see seasonal dust patterns from dry summer air. In Miami, the pattern is different: we see moisture-driven buildup near the coast and in homes that keep the thermostat low and the windows shut. Knowing which one applies to your house matters more than any national average.
This is also why you want a Miami crew, not a franchise dispatching from three counties away. The local knowledge shows up in the estimate.
Repair or Replace: When Cleaning Isn’t Enough
Sometimes cleaning is the answer. Sometimes it isn’t. If a duct run has collapsed, if insulation has come apart inside a flexible duct, or if a section has significant mold growth that can’t be fully remediated in place, replacing that section is the better use of your money. We’ll tell you which situation you’re in before you spend anything, and if section replacement is the right call, it’s priced separately and written down in advance.
What we won’t do is pressure you into either one. The Garrison Standard is straightforward: arrive inside the quoted window, price in writing, do the job by the book, leave the site clean. If cleaning will solve it, we clean it. If it won’t, we say so.
For homes where we do clean, we use equipment from Rotobrush, Nikro, Abatement Technologies, and filtration brands including Honeywell, Aprilaire, and Guardsman. These are the same tools commercial crews use. We explain what each piece does on your job, in plain terms, because you deserve to know what you paid for.
FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in Miami?
Most Miami homeowners pay between $350 and $700 for a single-system home with up to 10 vents. Two-system homes and homes with heavy contamination range from $800 to $1,500. Condos with one system often come in around $300 to $450. Call (361) 326-5060 for a free estimate written down before any work starts.
Is it worth getting my air ducts cleaned in Miami?
It is if your system shows signs of buildup, moisture, or poor airflow, which is common in Miami’s humid climate. If your ducts were cleaned recently and you change filters on schedule, you probably don’t need the full service. A short inspection will tell you which category you fall into, and we’ll be honest about it. Call (361) 326-5060 to schedule one.
Why is a $199 air duct cleaning special usually too good to be true?
Because $199 rarely covers the full job. Low teaser rates typically clean only the returns or use a single pass with no negative-air setup, which leaves loosened debris in the system. A proper cleaning with rotary brush agitation and negative-air containment starts around $350 in this market. If a quote is far below that, ask exactly what’s included and whether the price is written before work begins. Get your free written estimate at (361) 326-5060.
Is it cheaper to repair or replace ductwork in Miami?
Repair, in most cases. Spot-sealing and section replacement typically run $300 to $900 depending on length and access, while a full duct replacement can climb well past $3,000 to $6,000. Replacement only makes sense when large sections are collapsed, water-damaged beyond remediation, or sized wrong for the system. An inspection will tell you which one you need. Call (361) 326-5060 for a written estimate.
Can you clean my ducts the same day I call?
Often, yes, depending on schedule and system size. Simple single-system cleanings are frequently completed in a single visit of three to five hours. Larger two-system jobs may need to be scheduled. We answer the phone with a live person 24 hours a day, every day, so you won’t get a voicemail loop. Call (361) 326-5060 and we’ll tell you what’s available.
