Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
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?
Most air duct cleaning jobs in Miami run $350 to $700 for a typical single-family home, with the average landing around $480. A basic condo or apartment with one air handler usually comes in at $250 to $400, while larger homes with two or more systems, heavy mold concerns, or extended duct runs push past $900. Those numbers cover a real cleaning (rotary brush agitation plus HEPA vacuum extraction), not a technician walking through with a shop vac and calling it done.
We quote Miami jobs every week, so we know where the ranges come from. The wide spread comes down to three things: how many systems you have, how much square footage those ducts serve, and whether Miami’s humidity has done a number on the interior of the ductwork. By the end of this page, you’ll know exactly what you should be paying – and what would be a red flag.
Key Takeaways
- Typical Miami air duct cleaning: $350-$700, averaging about $480
- Condos and smaller systems: $250-$400
- Larger homes (2+ systems): $700-$1,200+
- You should always get a written price before any work starts – ours doesn’t change at the door
- Beware of $99 “whole home” specials; they rarely include actual equipment, containment, or vent-level cleaning
Air Duct Cleaning Cost Breakdown (2026)
Here’s how pricing actually gets built for a Miami home. We use line-item pricing so you can see what you’re paying for. If a company won’t break it down like this, that’s your answer about how the visit will go.
| Line Item | Typical Miami Range | Notes |
|---|---|---|
| Base cleaning, single system (up to ~12 vents) | $250 – $420 | Rotary brush agitation + HEPA extraction at every register |
| Additional system (second AC / air handler) | $150 – $300 | Common in 2-story homes and homes with a separate upstairs unit |
| Additional vent beyond the base count | $15 – $35 per vent | Vaulted ceilings and long runs cost more |
| Main trunk line cleaning | $80 – $200 | The big duct running off the air handler – often skipped by cheap providers |
| Mold remediation / antimicrobial fogging | $200 – $600 | Higher in Miami than most markets due to year-round humidity |
| Dryer vent cleaning (add-on) | $89 – $175 | Bundle it while the truck is already there |
| HVAC coil + blower cleaning (add-on) | $150 – $400 | Deep cleaning of the air handler itself, not just the ducts |
| Sanitizing / deodorizing treatment | $75 – $250 | Optional unless there’s pet, smoke, or mildew odor present |
| Camera inspection (before/after video) | $0 – $150 | Often included; ask before you book |
What pushes the price up in Miami versus, say, a dry market? Number of systems and mold remediation. Nearly every home here runs AC year-round, which means condensation in the ductwork, which means that particular smell in a Coral Gables or Coconut Grove home that didn’t come from the trash. When we find visible growth, remediation isn’t optional – it’s the difference between cleaning and repeating.
What pushes the price down? A single-system condo in Brickell or Downtown Miami with accessible vents and no moisture history is the cheapest legitimate job there is. Simple layout, one handler, easy ladder work.
If you’d like a written price for your specific home before you commit to anything, Cardinal Air Duct Cleaning hands it to you first, then touches nothing until you say go. Call (737) 727-2314 and we’ll quote it over the phone in about five minutes.
What Affects Air Duct Cleaning Pricing in Miami
- Number of HVAC systems. Most Miami single-family homes have one system. Two-story homes in Kendall, Palmetto Bay, and Pinecrest often have two, which nearly doubles the labor because each air handler and its duct branches must be cleaned separately.
- Square footage and duct run length. A 1,200 sq ft Miami Beach condo has short duct runs. A 3,500 sq ft home in The Hammocks can have 60+ feet of trunk line and 20+ vents. You’re paying for time and equipment passes, so longer runs cost more.
- Vent accessibility. Vents buried behind furniture, up in a vaulted ceiling, or behind a soffit take longer to reach. If you’re in a home with a two-story foyer, expect a small upcharge for the tall work.
- Moisture and mold conditions. This is the Miami-specific factor. Humidity in ductwork that never fully dries creates conditions for microbial growth. When we find it, remediation – not just cleaning – is required, and that adds $200-$600. Homes near the water (Coconut Grove, Key Biscayne, Miami Beach) see this more often.
- Contamination level. Recent renovation dust, pet dander, cigarette smoke, or years of neglect each raise the workload. A new-construction dust-out is different from a 15-year-old system that’s never been touched.
- Equipment quality and containment. Providers running proper gear – Rotobrush rotary brushes, Nikro HEPA vacuums, Abatement Technologies negative-air containment – charge more than a guy with a shop vac. There’s a reason. The cheap setup puts the debris back into your living room.
How the Equipment Affects What You Pay
When a quote looks unusually low, ask what equipment is coming. Rotobrush systems use a rotary brush to physically agitate debris off the duct walls; Nikro HEPA vacuums pull it into a sealed container with a filter fine enough to trap particles you can’t see. Abatement Technologies containment units create negative pressure at the register, which means loosened debris goes straight into the vacuum, not back into your living room. That combination is what you’re paying for. A shop vac and a leaf blower aren’t the same service, even if the invoice says “air duct cleaning.”
How to Save on Air Duct Cleaning
You can lower your cost without lowering the quality. Here’s what actually works in the Miami market.
- Bundle services. Dryer vent cleaning runs $89-$175 on its own, but if the truck is already parked, the incremental cost drops. Same with HVAC coil cleaning. Ask for a combined quote.
- Book in the shoulder season. Late spring and early fall – May and October in Miami – are slower. Prices don’t formally drop, but scheduling is easier and you’ll catch more availability on short notice.
- Get the written quote over the phone before the visit. An upfront written price is how you avoid the classic “once we got inside, it turned out to be more” pitch. If you want the price in writing before we set foot in the house, that’s our standard, not a favor. The written price we give you doesn’t change at the door.
- Skip the sanitizing treatment unless you need it. If there’s no pet, smoke, or musty odor, antimicrobial fogging is optional. Save the $75-$250.
- Don’t chase the $99 special. It’s a loss-leader that turns into a $1,200 bill at the kitchen table. Every year we get called to fix one. The cleaning was partial, the containment was nonexistent, and the homeowner ends up paying twice – once to the first company, once to us.
- Ask what’s included. Trunk line? Air handler? Vent-level agitation? Camera documentation? The lowest quote is often the one missing the most work.
Free estimates are the standard here, so there’s no reason to commit before you’ve seen a number. Call (737) 727-2314 and we’ll walk your home over the phone, then put it in writing.

FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in Miami?
Expect $350 to $700 for a typical single-family home in Miami, averaging around $480. Condos and smaller systems run $250-$400. Larger homes with two systems, mold remediation, or extended duct runs can exceed $900. Call (737) 727-2314 for an exact quote – estimates are free and you’ll have the number in writing before we schedule.
Is it cheaper to clean ducts or replace them?
Cleaning is dramatically cheaper – duct replacement runs $3,000-$8,000 or more in Miami, versus $350-$700 for cleaning. Replacement only makes sense when the ductwork itself is failing: crushed flex duct, rodent damage, or ducts installed inside a humid attic with no insulation. Most Miami homes can be cleaned and returned to service rather than replaced. We’ll tell you which category yours is in during the free estimate.
Do I really need duct cleaning in Miami, or is it a scam?
Miami’s year-round humidity makes it one of the few markets where duct cleaning is genuinely worth the money on a recurring basis. The AC runs 10-11 months a year, condensation forms inside the ductwork, and without periodic cleaning that moisture traps dust, pollen, and biological material. The scam version is the “$99 whole house” ad that turns into a $1,000 upsell. The legitimate version is $350-$700 for real rotary brush and HEPA extraction at every vent, with documentation of what was removed. Call (737) 727-2314 and ask specifically what’s included in the base price.
How long does air duct cleaning take in a Miami home?
A typical single-system home takes 2-4 hours. A two-system home with 20+ vents and mold remediation can take 5-6 hours. The price you’re quoted should match the scope – if someone promises a full deep clean in 45 minutes, they’re not doing the work that justifies the number. We give you an arrival window you can track and we stay until the job is done and photographed.
Does Cardinal Air Duct Cleaning offer free estimates?
Yes – free estimates, written price before any work starts, and a written guarantee on every repair. Our 365-Day Done Right Promise means if the work isn’t right within 365 days, we return and correct it at no charge. If a repair fails, you get a free second visit. Call (737) 727-2314 any time – a live person answers 24/7.
What about dryer vent cleaning – is it cheaper?
Dryer vent cleaning runs $89-$175 in Miami when booked on its own, and less when bundled with air duct cleaning since the truck is already on site. It’s a real safety issue in humid climates where lint traps moisture and compacts. If you’re getting ducts done, add it. More detail is available on our dryer vent cleaning in Miami service page.

- What equipment are you using – rotary brush, HEPA, containment?
- Does the base price include the trunk line and air handler, or just the vents?
- Do I get before-and-after photos?
- What’s the guarantee window?
Our answers: yes, it’s written and it doesn’t change; Rotobrush + Nikro + Abatement Technologies; the trunk line and air handler are part of the quote; yes, documented photos; and 365 days. Every time.
