Duct cleaning matters more in South Florida than it does almost anywhere else, and the reason is humidity. Ductwork here runs cold air through hot, damp spaces — attics, crawl areas, unconditioned chases — and any place cold metal meets moist air is a place condensation forms. Add household dust and you have created exactly the conditions mold needs. We clean, sanitize and seal duct systems across Miami-Dade and Broward so your air handler is circulating air rather than recirculating a problem.
Most homeowners call us because of something they noticed rather than something they measured: a musty smell that arrives with the AC and fades when it shuts off, dust settling back onto furniture a day after cleaning, allergy symptoms that are worse indoors than out, or visible dark specks around the supply registers. Those are the honest early signs, and they are worth taking seriously here.
A real duct cleaning is not a vacuum hose held to the register grille. We put the system under negative pressure, work each branch mechanically with brushes and agitation so the debris is loosened rather than pushed further in, and capture it in a HEPA-filtered collection unit. We clean the supply side, the return side, the plenum and the blower compartment — because the blower and the coil are where a lot of the buildup actually lives.
While we are in the system we also look at what caused the buildup. Torn flex duct, disconnected boots above the ceiling, crushed runs, missing insulation and leaking joints all pull humid attic air into a system that is supposed to be sealed. Cleaning a system with a torn return and not mentioning it would be a waste of your money, so we show you what we find and quote the repair separately.
What our Miami air duct cleaning service includes
- Whole-system cleaning — supply runs, return runs, main trunk and plenum
- Negative-pressure HEPA collection so debris leaves the house rather than moving around it
- Mechanical agitation with brushes and air whips, not suction alone
- Blower compartment and evaporator coil cleaning, where much of the buildup actually sits
- Antimicrobial sanitizing treatment for systems showing mold or persistent odor
- Register and grille removal, cleaning and refitting
- Dryer vent cleaning — a genuine fire risk when lint has been building for years
- Inspection for torn flex duct, disconnected boots, crushed runs and leaking joints
- Before-and-after photographs from inside the ducts so you can see the difference
Why homeowners in Florida call us
- We work in South Florida humidity every day and know how duct systems fail here specifically
- Mechanical cleaning with contained HEPA collection, not a hose at the vent
- We photograph inside the ducts before and after — you see the actual result
- We flag duct damage and air leaks rather than cleaning around them quietly
- HVAC technicians on staff, so duct repair and air handler issues are handled by the same company
- Serving Miami, Hialeah, Coral Gables, Kendall, Doral, Homestead and surrounding communities
What affects the cost
Duct cleaning quotes vary because duct systems vary. The factors that actually change the price:
- Number of supply and return vents in the home
- Number of separate air handler systems — a two-system house is close to two jobs
- Square footage and total length of duct run
- Accessibility — a tight attic in August is slower work than an accessible crawl space
- Whether antimicrobial sanitizing treatment is needed on top of cleaning
- Condition of the system, including any duct repair or sealing found during the work
- Whether dryer vent cleaning is added to the same visit
Every quote is free and specific to your property — we do not price this kind of work over the phone without understanding what is actually there.

Frequently asked questions
How often should air ducts be cleaned in South Florida?
Every three to five years is a reasonable interval for most Miami homes, which is more frequent than the national guidance because of our humidity. Sooner if you have had water intrusion, a renovation, visible mold, persistent musty smells, or new pets or allergy sufferers in the house.
Does duct cleaning actually help with allergies?
It helps when the duct system is genuinely part of the problem — visible debris, mold growth, rodent or insect activity, or post-construction dust. It is not a cure for allergies in general. We will tell you honestly if what we see in your system does not look like a plausible cause of the symptoms you are describing.
How long does the job take?
A typical single-system Miami home is usually a half day. Larger homes, homes with two or three air handlers, and systems that need sanitizing treatment run longer. We would rather take the extra time than skip the return side.
What is the difference between cleaning and sanitizing?
Cleaning physically removes the debris. Sanitizing applies an antimicrobial treatment to surfaces afterward to address microbial growth. Sanitizing without cleaning first is close to pointless — you are treating the surface of a layer of dust. We only recommend sanitizing when there is a reason for it.
Will you tell me if I do not need it?
Yes. We inspect the system before quoting, and if the ducts are genuinely clean we will say so. It is a better outcome for us than a customer who paid for something they did not need.
Do you clean dryer vents too?
Yes, and it is worth doing. Lint buildup in a dryer vent is a real fire hazard, and long or restricted vent runs — common in Florida townhomes and condos — make it worse. Longer drying times are the usual first sign.
