AfterHow Much Does Duct Cleaning Cost in Miami?
Duct cleaning in Miami typically runs between $285 and $490 for a standard single-family home, with most homeowners paying around $375 for a full-system cleaning that includes supply and return ducts, the main trunk line, and the air handler. Larger homes with two systems or heavily contaminated ductwork can push the total to $650 or more. At Coldharbour Heating & Air, we give you a written price before any equipment comes off the truck, so the number you approve is the number you pay, not a starting point.
Key Takeaways
- Standard duct cleaning in Miami: $285 – $490 for most homes under 2,500 square feet
- Larger homes or dual-system properties: $500 – $750+
- Most jobs take 3 to 5 hours, same-day or next-day scheduling
- A written price is handed to you before work begins, guaranteed
- Coldharbour has served Miami since 2003, with live phone coverage 24/7
Duct Cleaning Cost Breakdown (2026)
Here’s what we’re seeing across Miami in 2026, based on actual job scopes rather than national averages. These are real numbers from the Miami market, from single-family homes in Kendall to condos in Brickell and older properties in Little Havana.
Standard Duct Cleaning by Home Size
- Condos and apartments (under 1,000 sq ft): $195 – $285
- Single-family home, one system (1,000 – 2,500 sq ft): $285 – $490
- Larger home, one system (2,500 – 4,000 sq ft): $425 – $625
- Two-system home or very large property (4,000+ sq ft): $550 – $750+
Line-Item Costs for Add-On Services
- Second return or supply plenum cleaning: $60 – $95 each
- Air handler coil cleaning (evaporator coil): $110 – $190
- Blower motor and housing cleaning: $80 – $135
- Sanitizing fog or antimicrobial application after cleaning: $95 – $180
- Dryer vent cleaning (often bundled with duct cleaning): $85 – $150
- Replacing a damaged flex duct run: $75 – $140 per run
What pushes the price up or down is mostly access and condition. In older Miami neighborhoods like Shenandoah or the Roads, we regularly find duct systems packed with decades of dust, drywall debris from past renovations, and sometimes construction trash from sloppy remodel jobs. That takes longer to do right and costs more. A newer home in Doral or Pinecrest with a clean system and easy attic access lands at the lower end of the range.
The second driver is the number of vents and the layout of the system. A home with 18 registers spread across two floors takes longer to clean properly than a 10-register ranch. We count every register, every return, and the full trunk line in our written quote, so there’s no surprise add-on when the technician arrives.
What Affects Duct Cleaning Pricing in Miami
- Mold and humidity exposure. Miami’s constant moisture means ducts here grow mold faster than in drier climates. If we find mold in the duct lining or around the air handler, remediation adds $150 – $350 depending on how far it has spread. We’ll show you what we found before we quote the add-on.
- Age and condition of the ductwork. Homes built before 1990 in areas like Olympia Heights or Westchester often have older flex duct that has degraded or collapsed. If a section needs replacing, that’s a separate line item, not a surprise lump sum.
- Access to the air handler and plenum. In many Miami attics, the air handler sits in a tight corner under a low roof pitch. If we need extra time to reach and clean the plenum properly, that’s reflected in the quote up front, not discovered mid-job.
- Pet hair and heavy buildup. Homes with multiple dogs or cats, especially long-haired breeds, develop a thick layer of hair inside return ducts. This takes longer to extract and can add $75 – $140 to the final price.
- Post-construction dust. If you’ve recently renovated, drywall dust and debris settle into the entire duct system. A full post-construction cleaning, which includes deep extraction from every register and the trunk line, runs $350 – $550 in Miami.
- System count. A two-story home with separate systems upstairs and downstairs is effectively two cleaning jobs. Expect to pay on the higher end of the range and add $200 – $300 for the second system.
How to Save on Duct Cleaning
Duct cleaning doesn’t have to be a budget-breaker, and there are a few things Miami homeowners can do to keep the price down without cutting corners on quality.
- Bundle dryer vent cleaning with your duct cleaning. Most companies, including us, discount the dryer vent when it’s added to a full duct job. You’ll save $40 – $60 compared to booking separately.
- Change your filters regularly before the appointment. A clogged filter means the system has been pulling harder and likely pulled more debris into the ducts. Fresh filters before and after cleaning keep the system cleaner longer and may reduce the work needed on the return side.
- Ask about off-peak scheduling. While we don’t run scarcity-style discounts, some months are slower for HVAC work in Miami. You can call (850) 810-1910 and ask what the current schedule looks like, and whether a midweek or same-week slot works for a better rate.
- Get your free estimate in writing. There’s no charge for the estimate, and you’ll know the exact cost before you commit. No pressure, no door-knocking upcharge. Call (850) 810-1910 and ask for a duct cleaning quote.
Is Duct Cleaning Worth the Cost in Miami?
For most Miami homes, yes, with one caveat: the duct cleaning has to be done correctly. A proper cleaning removes the accumulated dust, pet hair, and sometimes mold from the entire system, not just the visible registers. Here’s what that actually buys you in a city where the AC runs most of the year.
Better airflow and lower strain on the system. When ducts are clogged, your air handler works harder to push the same amount of cooled air. A clean system moves air more efficiently, which can reduce wear on the blower motor. In Miami, where the AC runs 10 to 11 months out of the year, that’s a real difference.
Less dust settling back into the living space. If you dust your furniture on Sunday and it’s coated again by Wednesday, your ducts are likely recirculating dust through the house. A proper duct cleaning removes that reservoir, and homeowners in neighborhoods like Kendall and Palmetto Bay tell us they notice the difference within a week.
Mold and mildew control. Miami’s summer humidity is relentless. Ducts that sit in a hot, moist attic can develop mold inside the duct lining. Cleaning removes the visible mold and the debris that feeds it. If you have persistent musty odors when the AC kicks on, it’s worth having the ducts inspected, and a cleaning is usually the fix.
Where it’s not worth the cost is when a company knocks on your door offering $99 whole-house duct cleaning as a “special.” In this market, a real cleaning at that price either skips the trunk line, uses a shop vac on the first few registers and calls it done, or is a lead-in to an aggressive sales pitch. You get what you pay for.
How Duct Cleaning Works: What We Actually Do
We believe you should know what you’re paying for. Here’s the process our technicians follow on every duct cleaning in Miami, start to finish. It’s the same standard for every home, whether it’s a condo in Edgewater or a house in Cutler Bay.
- Inspection and written quote. We walk the system with you: air handler, return, trunk line, and registers. We note access points and any visible mold or damage. Then we hand you a written quote that does not change at the door.
- Seal off registers and create negative pressure. We connect a high-powered vacuum to the main trunk line to pull dust and debris out of the system as we work, not blow it back into your house.
- Agitate and extract from every register. Each supply register is cleaned individually with air whips and brushes, pushing debris toward the vacuum. We don’t just vacuum the face of the register; we clean the full run back to the trunk.
- Clean the return side and the air handler. The return pulls the most air and typically holds the most debris. We clean the return plenum, the blower motor housing, and the evaporator coil if accessible.
- Final walkthrough and before/after. We show you what came out of your ducts, and we point out anything we saw that might need attention (a loose connection, a tear in the flex duct, a coil that’s overdue for cleaning).
- Written guarantee. Every cleaning from Coldharbour Heating & Air comes with the Kingswell guarantee in writing. If something’s not right, we come back.

Red Flags That a “Cheap” Duct Cleaning Will Cost You More
Miami sees a lot of fly-by-night duct cleaning outfits, especially after the summer storms knock debris loose across neighborhoods like Coconut Grove and South Miami. Here’s what to watch for.
- $99 whole-house specials. A legitimate duct cleaning on a 2,000-square-foot Miami home takes 3 to 5 hours with proper equipment. Anyone offering the full job for $99 is either skipping most of the system or planning to upsell you hard once they’re in the door.
- “Mold testing” that conveniently finds mold. This is a known bait-and-switch in the Miami market. The company offers cheap cleaning, then “discovers” mold and pressures you into a $1,500 “sanitizing” package. Real mold is visible. We’ll show it to you and let you decide.
- No written quote before work begins. If a company won’t hand you a price on paper before starting, walk away. That’s the single biggest signal that the final bill won’t match the phone estimate. Victor Mancini has insisted on written-before-work pricing at Coldharbour since 2003, and it’s non-negotiable.
- No mention of the return side or air handler. Some outfits clean only the supply registers, which is like washing half of a dirty floor. A real cleaning includes the return plenum and the air handler.
FAQs – Duct Cleaning Cost
How much does duct cleaning cost in Miami?
Standard duct cleaning in Miami runs $285 – $490 for most single-family homes, with larger homes or dual-system properties ranging from $550 – $750+. The exact price depends on system size, access, and condition. Call (850) 810-1910 for a free written estimate based on your home’s actual system.
Is it cheaper to clean ducts or replace them?
Cleaning is far cheaper than replacing. Duct cleaning runs $285 – $490 in most Miami homes, while full duct replacement typically starts at $3,000 and climbs past $6,000. If your ducts are intact and just dirty, cleaning is the obvious choice. If they’re torn, collapsed, or filled with mold that penetrates the lining, replacement may be necessary. We’ll tell you honestly which one you need.
How often should ducts be cleaned in Miami?
Every 3 to 5 years is the right interval for most Miami homes, given our humidity and year-round AC use. Homes with pets, recent renovations, or visible mold growth may need it every 2 to 3 years. Call (850) 810-1910 and we’ll help you figure out whether you’re due.
Does duct cleaning remove mold?
Duct cleaning removes visible surface mold from duct linings and the air handler in most cases, typically included in the base price of $285 – $490 for standard homes. If mold has penetrated deep into the duct material or insulation, that requires more aggressive treatment or duct replacement, which costs more. We’ll show you what we find before any add-on work is quoted.
Can you come today for a duct cleaning?
Often, yes. We keep same-day and next-day slots open for duct cleaning across Miami. A live person answers the phone 24/7, so you can call (850) 810-1910 at any hour and book a firm arrival window. No voicemail tree, no waiting until morning.
Why do some Miami companies charge $99 and others charge $400+ for the same job?
The $99 companies aren’t doing the same job. A real duct cleaning in Miami takes 3 to 5 hours and includes the trunk line, return plenum, air handler, and every register. The $99 special typically covers a handful of visible registers and skips the rest. You end up paying twice: once for the cheap job, and again for a real cleaning when the dust comes back in a month.
