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.

AfterFast, Reliable Air Duct Cleaning Across South Miami
Most South Miami homeowners pay between $380 and $620 for a full residential air duct cleaning, with commercial systems running $850 to $1,400 depending on the square footage and access. Our crews dispatch from the Miami office and typically schedule South Miami jobs within three to five business days. Call (469) 972-3151 for a written estimate before any work begins.
We know the streets here. From the tight grid of CBS ranch homes south of Sunset Drive to the concrete bungalows near Ludlam Road, South Miami’s housing stock presents duct problems you won’t find in newer developments. Our technicians carry Rotobrush rotary systems and Nikro negative-pressure units through attics that hit 130°F in July, because that’s what it takes to do source removal on ductwork that was retrofitted, not engineered, for these spaces. If you live in South Miami and your registers blow musty air even after you change the filter, the problem is almost certainly inside the ducts, not the AC unit itself.
Why Kestrel Air Duct Cleaning Is South Miami’s Preferred Air Duct Cleaning Company
We’ve been working under the Kingswell Guarantee since 2004, and that standard travels with us into every South Miami attic. The four promises never change: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if the work fails within the guarantee period.
South Miami customers call us back because we answer the phone with a live person, 24/7, not an automated queue. Dale Whitmore built this operation on accountability, not volume. Our technicians are background-checked and uniformed, and they show up in the window we gave you. No “between 8 and 5” nonsense. We leave the place cleaner than we found it, and we put the 365-Day Done Right Promise in writing on every single job. If it’s not done right, we make it right at no charge. That’s documented, not discretionary.
Our Air Duct Cleaning team has handled the specific failure modes of South Miami’s older housing stock: crumbling 1970s fibrous-glass duct liner, mold-colonized flex duct stapled through unconditioned attics, and air handlers caked with debris that keeps re-contaminating the system. We don’t fog chemicals and call it clean. We remove the source.
Commercial Air Duct Cleaning in South Miami
Commercial Air Duct Cleaning in South Miami covers office suites, retail spaces, medical clinics, and small commercial buildings where the HVAC system runs continuously through the wet season and dry season alike. Because South Miami’s commercial core mixes mid-century construction with newer infill, we often find rooftop package units with ductwork that hasn’t been opened in fifteen years, blowing accumulated moisture and microbial debris into occupied spaces. A typical commercial cleaning in South Miami runs $850-$1,400 for systems under 5,000 square feet, with larger buildings quoted after a walkthrough. We always provide a written price before any register is touched.
System Inspection and Access Planning
Commercial buildings on US 1 and Sunset Drive often have limited plenum access or rooftop units requiring ladder and safety setup. Our crew photographs the system layout, identifies all supply and return points, and plans negative-air containment before starting. No surprises, no scope creep.
HEPA-Contained Source Removal
We use Abatement Technologies portable HEPA filtration units during commercial jobs to capture particles at the source, not redistribute them through the occupied space. This matters in South Miami, where near-constant AC cycling means any loosened debris would otherwise recirculate immediately.
Air Duct Cleaning Services in South Miami
Air Duct Cleaning Services in South Miami address the reality that most residential systems here run eleven to twelve months a year with almost no seasonal downtime. The dominant driver for cleaning isn’t dust accumulation, it’s moisture-driven microbial growth inside duct surfaces that never fully dry out. A typical full-system residential cleaning in South Miami runs $380-$620, covering all supply and return ducts, the air handler cabinet, and the blower motor. We perform video inspection before and after so you see what was actually removed, not just what we claim.
Residential Full System Cleaning
Our residential process starts with register removal and camera inspection of each branch. On a 1962 CBS ranch off Sunset Drive, our tech pulled a register and found the original 1970s fibrous-glass liner crumbling inside the supply and return ducts, blowing loose particles past grilles that looked clean from the living room. We set up negative pressure with HEPA filtration, ran camera inspection and agitation tools through the flex runs stapled across the 130°F attic cavity, and performed source removal on the air handler and blower motor before sealing the ducts. No fogging “sanitiser” upsell, because no EPA-registered product applied over visible soil does anything but make the grille smell different.
Video Inspection and Documentation
Every South Miami job includes before-and-after video of the duct interior. Homeowners on Ludlam Road and Sunset Drive blocks have used this footage to document conditions for insurance claims or to decide whether duct replacement makes more sense than cleaning. The video is yours to keep.

Common Air Duct Cleaning Problems We See in South Miami Homes
- Mold colonization inside aged flex duct. South Miami’s 80% wet-season humidity and year-round AC cycling create condensation on poorly insulated duct surfaces in unconditioned attics. The mold isn’t on the grille; it’s ten feet back in the flex run where you can’t see it without a camera.
- Crumbling 1970s fibrous-glass duct liner. Original liner in CBS ranch homes south of Sunset Drive has baked through forty summers of 130°F attic heat. It degrades into loose particles that blow directly into living spaces, and homeowners almost never suspect because the visible grilles look fine.
- Re-contamination from dirty air handlers. Contractors who skip the blower motor and evaporator coil leave the reservoir intact. Every time the system cycles, it re-seeds the “cleaned” ducts with the same mold and debris. Source removal means the whole system, not just the easy reaches.
- Fogging “sanitiser” sold as a fix. Misting a chemical over colonized fibrous-glass liner does nothing about the moisture source, and no EPA-registered product claims to clean over visible soil. It changes the smell. It doesn’t change the problem.

A typical residential full-system cleaning in South Miami runs $380-$620. Commercial systems start at $850 and typically top out around $1,400 for spaces under 5,000 square feet. What moves you within that range: the number of supply and return branches, whether the air handler requires full disassembly for access, and the condition of the duct liner (intact liner cleans; crumbling liner often needs replacement, which we quote separately).

FAQs About Air Duct Cleaning in South Miami
South Miami sits several miles inland from Biscayne Bay without the coastal breeze that tempers humidity in Coconut Grove or Miami Beach, so average wet-season relative humidity hovers near 80% and AC systems run 11-12 months a year. That near-constant moisture and zero seasonal drying period lets mold establish inside duct surfaces that would dry out seasonally in northern climates. Call (469) 972-3151 for a free inspection if you smell musty air from your registers.
A real cleaning performs source removal: mechanical brush agitation to dislodge growth from duct walls, negative-air extraction to pull it out of the system, and HEPA filtration to keep it out of your living space during the process. Fogging a chemical over visible mold does not constitute cleaning under NADCA standards, and no EPA-registered product claims to sanitize over visible soil. We document the before and after with video.
Yes. On homes south of Sunset Drive and in the 1940s bungalow blocks near Ludlam Road, we inspect attic flex runs and original sheet-metal condition before confirming the written price. The quote may shift if we find crumbling duct liner that requires replacement rather than cleaning, but that determination happens before work starts, not after. Call (469) 972-3151 to schedule a no-charge assessment.
If the fibrous-glass liner is intact but dirty, source removal cleans it. If it has degraded into loose particles, as we routinely find in 1970s South Miami systems, cleaning removes the debris but the liner will continue shedding. We show you the camera footage and quote replacement separately if needed. The decision is yours with the facts in hand.
Because South Miami systems cycle almost continuously, any mold or debris left in the air handler re-contaminates the supply and return ducts within days. Skipping the blower motor and evaporator coil is like washing your hands and drying them on a dirty towel. Our full-system price includes the air handler cabinet, blower wheel, and accessible coil faces. Call (469) 972-3151 for an exact quote on your system.
