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.

AfterAir Duct Cleaning Company in South Miami Heights, FL
Air duct cleaning in South Miami Heights typically runs $350 – $650 for a whole-home system and is scheduled by appointment, not dispatched for same-day emergency service. The work here is shaped by subtropical humidity and older housing stock: most homes are 1950s – 1970s concrete-block ranches with original flex duct sweating in unvented attics where temperatures hit 140°F. That combination means South Miami Heights homeowners usually call us for musty odors and mold-driven contamination, not ordinary household dust. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we serve South Miami Heights from our Miami-area scheduling office. Call (361) 326-5060 for a free written estimate.
Why South Miami Heights Homes Are Different
South Miami Heights sits in one of the most humidity-battered, hurricane-exposed corridors of Miami-Dade County. The dominant housing stock is low-slung concrete-block ranch houses built between the 1950s and 1970s, which means the vast majority of air duct systems here are original or one-generation-old flex duct routed through unvented, unconditioned attics. Surface temperatures in those attics routinely hit 140°F, and relative humidity hovers near 90% for much of the year.
This isn’t a dust problem. It’s a condensation problem. The long rainy season from May through October drives near-constant condensation inside attic ductwork, making mold growth in flex duct liners a persistent issue, not a seasonal one. Hurricane season adds wind-driven rain intrusion through soffits and roof penetrations, wetting attic insulation and duct exteriors. Many homes still have original 1970s foil-wrapped flex with rodent damage from the nearby canal banks along the Black Creek corridor. When South Miami Heights homeowners notice that musty “attic smell” every June, it’s usually because the flex duct has been sweating all spring.
Slab-on-grade construction with no basements means all HVAC equipment and ductwork lives in the attic or a small utility closet. There’s no alternative routing, and no easy way to inspect without crawling that space. Some 1980s – 2000s infill townhomes and smaller CBS homes along the US-1 corridor present similar challenges on a smaller scale.
Our Main South Miami Heights Services
Homeowners in South Miami Heights call us most often for three jobs shaped by the area’s humidity, housing age, and attic conditions.
Air Duct Cleaning in South Miami Heights
Our air duct cleaning in South Miami Heights targets mold amplification, moisture contamination, and rodent-damaged flex duct common in the area’s 1950s – 1970s ranches. We use Rotobrush rotary brush systems and Nikro negative-air machines to dislodge and extract contamination from original foil-wrapped flex runs without tearing the fragile material. Every job starts with a written price that doesn’t change once we’re inside. Air Duct Cleaning in South Miami Heights
Dryer Vent Cleaning in South Miami Heights
Dryer vent cleaning in South Miami Heights addresses lint buildup compounded by high humidity that clogs exhaust runs faster than in drier climates. Many homes have long vent runs through slab-on-grade walls to exterior terminations, and the combination of moisture and lint creates dense blockages that extend drying times and create fire risk. We clean the full run from appliance to termination. Dryer Vent Cleaning in South Miami Heights
Duct Sealing in South Miami Heights
Duct sealing in South Miami Heights closes the gaps and disconnected joints that let 140°F attic air and humidity leak into conditioned supply air. In older flex duct systems, we apply duct sealing mastic at connection points and repair or replace collapsed runs where condensation has degraded the insulation. Sealed ducts reduce the load on AC equipment and cut the moisture intrusion that drives mold growth. Duct Sealing in South Miami Heights
