How Much Does Air Duct Cleaning Cost in Miami Gardens?

Air Duct Cleaning in Miami Gardens typically costs between $350 and $650 for a standard single-family home, with most homeowners paying around $450 for a full-system cleaning in 2026. If you add dryer vent cleaning or duct sealing, expect the total to run closer to $550 to $850. The final number depends on how many vents your home has, how long it’s been since the last cleaning, and whether you have mold, pests, or heavy construction dust in the ducts.

Air Duct Cleaning Cost Breakdown (2026)

Here is what we charge in Miami Gardens, based on what our team sees on real jobs. These are written price ranges, not teaser quotes.

Service	Price Range	What It Includes
Basic air duct cleaning (up to 10 vents)	$350 – $480	Supply and return ducts, registers, one filter change
Standard whole-home cleaning (11 – 20 vents)	$450 – $650	All ducts, registers, grilles, blower cabinet, main return
Larger homes (21+ vents) or two-zone systems	$650 – $900	Full system plus longer run times and extra access points
Dryer vent cleaning (add-on)	$89 – $160	Vent line from dryer to exterior, lint trap check
Duct sealing (add-on, per section)	$180 – $450	Mastic sealing of accessible joints and leaks
Sanitizing treatment (optional)	$120 – $280	EPA-registered antimicrobial fog after cleaning

These numbers come from cleanings performed across Miami Gardens neighborhoods, including Bunny Heights, Rolling Oaks, Andover, Lake Lucerne, and the areas around Hard Rock Stadium and the Palmetto Expressway corridor. Homes of similar size tend to fall in the same range, but two variables matter most: decades of dust and the distance between your registers and the main unit.

What Affects Air Duct Cleaning Pricing in Miami Gardens

The cost is not a mystery once you understand what you are paying for. Here are the specific factors that move the number up or down in this market.

• Number of vents and registers. A 1,300-square-foot home in Andover might have 8 supply vents, while a 3,200-square-foot two-story near Lake Lucerne has 22 or more. More vents means more access, more agitation, and more time.
• Mold or moisture in the ducts. Miami Gardens sits at roughly 10 feet above sea level with a tropical monsoon climate. Humidity runs high from May through October, and concealed condensation in ductwork is a common finding. If our camera inspection reveals microbial growth, the job requires sanitizing treatment and often duct sealing to stop the moisture source. That adds real cost for real reasons.
• Age of the system and prior cleanings. A home built in the 1990s with original ductwork and no record of cleaning will take longer than a 2018 build cleaned two years ago. In neighborhoods like Bunche Park and Norwood, we regularly work on homes where the ducts have not been touched since the house was built.
• Access to the air handler and main trunk line. Some older Miami Gardens homes have air handlers in tight attic spaces or closets with narrow access panels. If we cannot get a negative-air machine connected without extra work, the price reflects that access time.
• Pest intrusion. Droppings, nesting material, and dead insects in ductwork are not rare here, especially near canal-adjacent streets in the eastern section of the city. That requires removal, sealing of entry points, and sanitizing before the cleaning can be called complete.
• Presence of flexible ductwork. Most Miami Gardens homes built since the 1980s use flex duct. Older flex duct can tear if handled by a crew without proper tools. We use rotary brush systems from Rotobrush and negative-air machines from Nikro at controlled speeds to avoid damage. The age and condition of your flex duct affects how carefully and slowly the work must proceed.

How to Know If You Need Air Duct Cleaning, Not Just a Filter Change

You do not need to clean ducts every year. The National Air Duct Cleaners Association suggests every 3 to 5 years for most homes, but Miami Gardens has conditions that compress that timeline. Humidity is the big one. Dust cakes onto moisture inside ducts and hardens. Once that layer grows past a certain point, a $15 filter change is not doing the work anymore.

Here is what we tell homeowners to watch for. If you can see dust blowing from the registers when the AC kicks on, that is not normal. If the white walls near ceiling vents have gray streaks, that is duct discharge. If every room seems to collect a fresh film of dust within three days of wiping surfaces, your ducts are redistributing particulate from somewhere upstream. And if rooms at the far end of the house stay warm in August even though the unit runs constantly, airflow past restricted coils and dust-loaded ducts may be the problem.

What a Full Cleaning Actually Includes

Not all “cleanings” are the same, and this is where Miami Gardens homeowners get burned by low teaser prices. A complete air duct cleaning uses the negative-air method, which means we connect a vacuum system to create negative pressure inside the ductwork while agitating the walls with a rotary brush. The negative pressure pulls loosened debris to a collection point outside the house rather than letting it float into living spaces.

Here is the sequence our technicians follow on every Full System Cleaning:

1. Inspect the system with a remote video camera to identify buildup, moisture, or damage.
2. Protect the floors and furniture near every register.
3. Connect the Nikro negative-air machine to the main return or supply trunk.
4. Agitate each branch line with a Rotobrush rotary brush system at controlled speed.
5. Clean registers, grilles, and the blower compartment by hand.
6. Vacuum the main trunk line and return plenum.
7. Replace the air filter with a new one appropriate for your system.
8. Offer an optional sanitizing treatment if the camera showed microbial activity.
9. Walk you through the results while you watch the collection tank.

This is not a fifteen-minute blow-and-go. A typical Miami Gardens home takes 3 to 5 hours for a complete cleaning. If a company quotes you $99, ask them what exactly that includes. A single vent “cleaning” is not a system cleaning.

Is Duct Sealing Worth It? The Miami Gardens Angle

Duct sealing uses mastic, a thick paste applied over joints and seams inside accessible ductwork. It hardens over time and prevents conditioned air from leaking into unconditioned attics, walls, or crawlspaces. In Miami Gardens, leaky ducts cost you money every single day: the AC runs longer to compensate for air lost into the attic, and humid outdoor air gets pulled into the ductwork to replace it.

We charge $180 to $450 per section of sealing, depending on how many joints and runs need attention. It is often done the same day as a duct cleaning because the interior of the duct is already accessed. For homes over 20 years old with original flex duct, sealing regularly saves 10 to 20 percent on monthly cooling bills during the May to October stretch. That is not a small number when Florida Power & Light bills in this part of Miami-Dade run their highest.

Dryer Vent Cleaning: The Add-On That Pays for Itself

We clean dryer vents as a standalone service for $89 to $160, and we recommend adding it when we are already on site for duct cleaning. A clogged dryer vent in a Miami Gardens laundry room is a fire risk, plain and simple. Lint accumulated past the visible screen area can fill the vent line in as little as two years in homes where the dryer runs four or more loads a week.

The check is fast: we run a rotary brush through the full vent run from dryer to exterior, then clear the lint and verify airflow at the outlet. If the line is a long horizontal run through a slab or second-story wall, it takes longer and falls toward the upper end of that range.

How to Save on Air Duct Cleaning

You do not need to chase a coupon. You need to avoid paying twice, and you need to know what drives the price honestly. Here is what we tell friends of the business in Miami Gardens:

• Bundle ducts and dryer vent. Doing both in one trip is cheaper than two separate visits, and the dryer vent is not a luxury add-on in South Florida.
• Ask for duct sealing only where it is visually needed. A camera inspection shows exactly which joints leak. We quote sealing by the section you approve, not by the whole system.
• Change your filter every 60 days during AC season. It does not replace cleaning, but it extends the interval between cleanings and reduces the load we remove later.
• Keep records of prior cleanings. If you can show the system was cleaned two years ago and you have pets and construction history that is minimal, we may confirm the system is still clean with a camera inspection and send you on your way.

We do not offer lowball teaser prices because we have no interest in charging you later for what should have been included up front. The price is written down before we start, and it does not change.

FAQs – Air Duct Cleaning Cost

How much does air duct cleaning cost for a typical home in Miami Gardens?

Expect to pay between $350 and $650 for a standard single-family home. Homes over 2,500 square feet or with more than 20 vents typically fall in the $650 to $900 range. The exact price for your home is given up front after a quick conversation about vent count and system age. Call (850) 660-3272 for a free estimate.

Is it cheaper to clean air ducts or replace them?

Cleaning is almost always cheaper. A full cleaning runs $350 to $650, while replacing all the ductwork in a Miami Gardens home typically costs $2,500 to $5,000 or more. Replacement makes sense only when ducts are torn, collapsed, or contaminated beyond what agitation and sanitizing can resolve. Our camera inspection tells you which path you actually need. Call (850) 660-3272 to schedule an inspection.

How often should air ducts be cleaned in Miami Gardens?

Most homes in this area need cleaning every 3 to 5 years, but homes with pets, high humidity issues, or recent renovations may need it every 2 to 3 years. The camera inspection is the tiebreaker. If buildup is not visible, we will tell you to save your money and wait.

Can mold in air ducts be cleaned, or do the ducts need replacing?

If the mold is limited to the interior surface and the duct material is intact, cleaning plus an EPA-registered sanitizing treatment usually resolves it. That adds roughly $120 to $280 to the cleaning price. If the duct insulation is saturated or the flex duct is deteriorating, sealing or replacement may be needed. The camera tells the story. Call (850) 660-3272 and we will show you what we see.

How much does dryer vent cleaning cost in Miami Gardens?

Dryer vent cleaning runs $89 to $160 for a standard single-family home. Longer runs, second-story vent exits, or heavily compacted lint push the price toward the top of that range. It is a fast service and we can add it to any duct cleaning at a reduced bundle rate. Call (850) 660-3272 for an exact quote.

Is air duct cleaning covered by homeowners insurance?

Generally, no. Insurance covers sudden damage, like a fire or water event. Routine maintenance, including air duct and dryer vent cleaning, comes out of your pocket. The exception is when cleaning is part of a covered claim, such as smoke or water damage restoration. Worth checking with your carrier, but do not expect a check for routine service.

The Garrison Standard and What It Means on the Job

Hollis Air Duct Miami is independently owned and operated as part of the Garrison Partners family. That is not a marketing label. It means our technicians work under a written operating code called The Garrison Standard. On every job, we commit to four things in writing:

• Arrive inside the appointment window we quoted.
• Provide a written price before any work starts. That price is the price.
• Complete the job by the book, following the sequence we described when you booked.
• Leave the site as clean as we found it, with all debris removed from your property.

Every job also carries a 365-Day Done Right Promise. If the work does not hold up within a full year, we return and correct it at no charge. That includes a free second visit. You do not need to negotiate for that. It is part of what you paid for.

The equipment on the truck is the same gear Commercial Duct Cleaning crews use. We run Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. You do not need to know those brand names to get good results. But if a company shows up with a shop vacuum and a drill attachment, you are not getting a cleaning, you are getting a show.

Miami Gardens Specifics: What the Local Climate Does to Ducts

If you have lived in Miami Gardens for a full year, you already know the air in this city. The humidity shapes everything, including your ductwork. Here is what we see on job sites every week:

In the rainy season from May through early November, condensation forms on the outside of supply ducts that run through warm attics. Fine dust from inside the house sticks to that condensation and accumulates in layers. Over several years, that layer becomes dense enough to restrict airflow and harbor mold growth. Homes along NW 27th Avenue and the areas between the Golden Glades and the county line see this pattern constantly.

Construction dust is the other local factor. Miami Gardens has long stretches of infill development and renovation work around the Hard Rock Stadium area and commercial corridors like NW 183rd Street. Renovation dust finds its way into return air and settles in branch ducts. If you had work done on your home or construction next door, that dust is likely in your system now.

Pet hair, sand from trips and yard work, and the normal skin cell shedding of a household complete the picture. None of this is exotic. But when combined with moisture, it stays put until physically removed.

Questions to Ask Any Air Duct Cleaning Company Before You Book

We encourage you to put the same questions to any company you call in Miami Gardens. The answers will tell you more about the company than their brochure will.

• Do you use a negative-air machine, or just a vacuum? A full system cleaning requires negative-air containment. If they hesitate on this question, call someone else.
• Is the price you quote over the phone the price I pay? If they cannot say yes, expect the price to move at the door.
• How long will the cleaning take? A real whole-home cleaning in this market takes 3 to 5 hours. Anything under an hour is a vent dusting.
• Can I see the camera footage before and after? If the company does not run a camera, they cannot prove the work was done or needed in the first place.
• Who exactly is coming into my home? Ours are background-checked, uniformed technicians. You should know who to expect before they ring the bell.

Our home page covers the full range of services we offer, including dryer vent cleaning and duct sealing, so you have a clear picture of what a complete job looks like.

When to Book Air Duct Cleaning in Miami Gardens

The best time to book is before the heavy cooling season, which in Miami Gardens means February through April. That gets your system clear before the AC runs continuously from June through September. It also means schedules are easier to get and you are not waiting behind a line of emergency calls in midsummer.

That said, if you are noticing the warning signs now – visible dust at the registers, a musty smell when the AC starts, rooms that never cool – do not wait for a seasonal calendar. The cost of running a restricted system through three more months of Florida heat will exceed the cost of the cleaning.

We answer our phones 24 hours a day, 7 days a week with a live person. No voicemail loops, no call centers reading scripts. The person who answers can tell you about availability, pricing, and what to expect on the day of service.

Why Written Prices Matter in Miami Gardens

The air duct cleaning trade has a reputation problem, and it is earned. Lowball ads, door-to-door pitches, prices that shift once the technician is inside. That happens in every market in this country, and Miami Gardens is no different.

Our answer to that problem is boring and effective: we write the price down before any work starts, and that number is the number. No fuel surcharges, no “found something extra” surprises, no add-on pressure once the equipment is running. If we discover something during the camera inspection that genuinely changes the scope, we stop, show you the footage, and quote the change in writing. You decide. The decision is yours, not ours.

That approach has kept us in business since 2004. It is also why we can offer the 365-Day Done Right Promise without flinching. We know what the work costs because we do it the same way every time. By the book, every trip.
