Most Miami homeowners pay $270–$500 for a whole-home duct cleaning. We give you a written estimate before we start — no bait-and-switch, no pressure. Licensed HVAC contractor, BBB A+ rated.
The average air duct cleaning cost in Miami is $270–$500. These are our real prices and ranges based on actual jobs across Miami-Dade & Broward County. Your exact cost depends on vent count — we count them during the free estimate. Pricing is the same across all of Miami-Dade and Broward County — no travel fees, same per-vent rates whether you’re in Coral Gables or Fort Lauderdale.

We count every supply vent and return air grille in your home before quoting. This means you pay for what you actually have — not a flat rate padded for a 20-vent home when you only have 9. Most Miami homes have 8–15 vents. We’ll tell you exactly how many during the free estimate.
Most professional duct cleaning companies in Miami charge $25–$50 per vent. This per-vent model is more accurate and fair than flat-rate or per-square-foot pricing because every home has a different number of vents — a 2-bedroom condo might have 6, while a 4-bedroom house could have 20+.
Example calculation: A typical 3-bedroom Miami home with 12 supply vents and 2 return air grilles = 14 total vents. At $30 per vent, that’s $420 for the full home. We count every vent during your free estimate so there are no surprises.
Some companies advertise per-square-foot pricing, but that’s less accurate — a 1,500 sq ft home with 8 vents costs less to clean than a 1,500 sq ft home with 16 vents. Per-vent pricing ensures you only pay for what you actually have. AC vent cleaning cost is included in every duct cleaning package — vent cover removal, soaking, scrubbing, and antimicrobial treatment are all part of the service.
Six factors drive the final price. Here’s exactly what each one means for your bill.
The single biggest factor. Every supply vent and return air grille adds to the count. A studio condo might have 5 vents; a 2,500 sq ft home can have 20+. We count every one before quoting — no surprises.
Biggest cost driver — $25–$50 per ventLarger homes have longer trunk lines and more branch duct runs. More ductwork means more time with the HEPA vacuum and more material to clean. Square footage doesn’t always equal vent count, but it usually correlates.
Moderate impact — affects labor timeHeavily contaminated ducts — years of buildup, pet dander, post-renovation dust, mold — take significantly longer to clean. A duct system that hasn’t been cleaned in 10 years will cost more than one cleaned 3 years ago.
Adds time — heavily dirty = more laborVents in tight attic spaces, inside closets, or on very high ceilings take more time to access safely. Older Miami homes with non-standard duct configurations or flex duct that needs repositioning also add labor.
Situational — flagged in free estimateMiami’s humidity makes mold in ducts common. If we find visible mold, we recommend an antimicrobial treatment with an EPA-registered fogger. This adds to cost but is essential — cleaning moldy ducts without treatment just redistributes spores.
+$150–$400 if mold presentDryer vent cleaning, AC coil cleaning, UV light installation — each adds to total cost but also adds real value. We bundle these at a discount when done the same day. You decide after seeing the free estimate — no pressure upsells.
Optional — always quoted separatelyWe count your vents, assess the condition, and give you a written quote — for free. Takes about 20 minutes. No charge, no pressure.

Every month, Miami homeowners call us after being burned by low-price bait-and-switch companies. Here’s what actually happens.
A company advertises $99 whole-home duct cleaning. You book. A tech arrives — sometimes without proper HEPA equipment at all — and within 10 minutes declares you have “severe mold,” “biohazard contamination,” or “collapsed ductwork.” The real bill: $800, $1,500, sometimes $3,000. The $99 becomes a hostage fee. The work they actually do? Often less than what a legitimate cleaning delivers at $300–$400.
Miami’s year-round humidity makes mold in air ducts more common here than almost anywhere in the country. Air duct cleaning and sanitizing cost depends on whether the mold is surface-level or deep in the ductwork.
EPA-registered antimicrobial fogger applied after cleaning. Kills mold spores on contact. Included when visible mold is detected during standard duct cleaning.
Deep contamination requiring multiple treatment passes, possible duct lining replacement, and HEPA containment. Assessed during your free estimate — we photograph everything before quoting.
We assess mold severity during your free estimate and give you a written quote with photos before any work begins. No surprises, no upselling — you see exactly what we see.
Every job — no matter the home size — includes these steps. Nothing hidden, nothing extra.
We inspect your entire duct system, count all vents, and check for mold, blockages, or damage. We show you what we find — with photos — before we start.
We connect a truck-mounted HEPA vacuum to your duct system, creating negative air pressure so all debris is pulled OUT — not pushed into your living space.
Every vent cover comes off. We soak, scrub, and sanitize each one. The ductwork behind the vent gets brushed and vacuumed. Included at no extra charge.
The main trunk line that feeds all your vents gets vacuumed and brushed. Every branch duct gets addressed. This is where the bulk of debris accumulates.
Return air grilles — the larger vents that pull air back to your AC unit — are often the most contaminated. We clean and sanitize every return in your home.
We photograph before and after every job. You see exactly what we found and exactly what we cleaned. No guesswork, no vague claims — real proof of work done.

“They gave me an exact price before they started and stuck to it. No surprise charges, no pressure to add stuff. The $99 company I used before somehow charged me $900 when they were done. These guys charged exactly what they quoted.”
“I called three companies. One gave me $99, one was $800 on the phone, and these guys said ‘we need to count your vents first.’ That’s what trust looks like. Final price was $340 for 11 vents. Completely fair.”
“I asked them about mold because another company said I had ‘severe mold’ and wanted $2,000. These guys came, showed me photos — minor buildup on two vents. Treated it for $180 extra. Night and day difference.”
