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.

AfterLennox Air Duct Cleaning in Miami, CA | Kestrel Air Duct Cleaning
We’re an independent Air Duct Cleaning in Miami company that specializes in Lennox equipment, and the quick answer is this: Lennox air handlers in Miami fail differently than they do anywhere else, because Miami’s dew point and hurricane-outage pattern attack the cabinet gaskets, flex duct liners, and evaporator coils in ways that don’t happen in drier Sun Belt cities. A Lennox system in Phoenix has a dust problem. A Lennox system in Miami has a moisture problem. Call (469) 972-3151 and we’ll explain exactly what’s happening inside your ductwork before we ever touch a vent.
Why Miami Residents Choose Us for Lennox Service
Dale Whitmore, our owner, grew up in the San Fernando Valley and spent his early twenties doing general HVAC maintenance before he realized the duct side of the system was where most of the neglect lived. He’s been cleaning ducts across Los Angeles for well over a decade, and he’s the guy neighbors call when allergy season hits hard or a renovation stirs up years of settled dust. When it comes to Lennox equipment specifically, we know the sealed blower decks, cabinet gaskets, and flex duct runs that Lennox builds, and we know how South Florida’s humidity makes each of those components fail sooner than it should. You get real local knowledge paired with real Lennox experience, not a franchise tech reading a script.
We’re not manufacturer-affiliated or authorized by Lennox. We’re independent, which means we tell you the truth about your system without a corporate sales quota behind it. If your Lennox air handler needs cleaning, we clean it. If the flex duct needs replacement, we show you the video and let you decide.
Common Lennox Air Duct Cleaning Problems We Solve in Miami
- Cabinet gasket and joint-tape failure in 130°F+ attics. Miami summer attic temperatures regularly exceed 130°F, and Lennox cabinet gaskets plus the factory joint tape degrade under that kind of sustained heat. Once the seal fails, humid outdoor air gets pulled into the supply path and condenses on the galvanized sheet metal, which feeds mold growth and rust. We find this on Lennox systems all over Miami, particularly in post-WWII concrete block homes where the air handler sits in an unconditioned attic.
- Flex duct inner-liner delamination on 1970s-90s Lennox retrofit jobs. Miami’s dominant housing stock was built between the 1950s and 1980s, and most of those homes had flexible duct retrofitted into attics decades ago. On Lennox retrofit jobs from that era, the flex duct vapor barrier degrades and the inner liner delaminates, releasing fiberglass particles into the airstream. Homeowners in Miami notice it as a fine gray dust on registers or a persistent throat irritation when the AC runs.
- Mold colonization on the evaporator coil and drain pan. This one’s tied to Miami’s humidity more than any other factor. Lennox air handlers with oversized cooling capacity run short cycles, which means the coil never fully dries between runs. Add Miami’s year-round 75-80% relative humidity, and the coil and drain pan stay wet for days at a time. Mold colonizes in years here, not decades. We clean evaporator coils with professional-grade equipment designed to pull the contamination out without blowing it through your living space.
- Salt-air corrosion on air handler cabinets and metal collars. Miami Beach, Brickell, and Edgewater sit close enough to the Atlantic and Biscayne Bay that salt-laden air accelerates corrosion on metal duct components and Lennox air handler cabinets. The rough, pitted surfaces trap biofilm, which then catches dust and mold spores. It’s a compounding problem most inland Miami homes never see at this intensity.
- Hurricane-outage mold blooms inside flex duct. After any tropical storm or hurricane that knocks out AC for even 48-72 hours, Miami duct cleaners see a predictable surge in mold remediation calls. Stagnant indoor air at 85°F and 90%+ relative humidity is enough to trigger visible mold growth on previously clean Lennox flex duct liner. We’ve seen it dozens of times, and most homeowners are shocked at how fast it appeared.
Lennox Service in Miami: What Local Conditions Mean for Your Equipment
Here’s the thing most Lennox owners in Miami don’t know until it happens to them: a 48-72 hour AC outage after a tropical storm is long enough to grow visible mold inside ductwork that inspected clean days earlier. Miami’s outdoor dew point sits above 70°F from April through October, and when your AC stops, the indoor air temperature climbs to 85°F while relative humidity holds at 90% or higher. Those are laboratory-grade mold incubation conditions. The flex duct inner liner, which is a slightly fibrous surface even when new, becomes a food source the moment condensation starts forming. We’ve video-inspected Lennox systems in Brickell and Miami Beach where black streaking appeared on the evaporator coil and wet flex liner within three days of an outage. That failure mode essentially doesn’t exist in Phoenix, Las Vegas, or inland California. It’s a Miami problem, and it means Lennox air duct cleaning here is a genuine indoor-air-quality intervention, not the optional maintenance service it is in drier climates. No neighboring Sun Belt city matches Miami’s combination of sustained high dew points and essentially uninterrupted cooling-season operation.
Lennox Models & Products We Service in Miami
We service all current Lennox residential lines: the Merit Series, Elite Series, and Dave Lennox Signature Collection. We also work on legacy Lennox CompleteHeat systems, which have their own wiring and blower quirks that a general duct cleaner won’t recognize. For parts, we use OEM-equivalent Lennox flex duct, sealed gaskets, and mastic-compatible sealants rather than off-brand tape, which fails faster in Miami’s heat and humidity. That matters more than most people realize, because a cheap tape job at 130°F attic temperature starts peeling within a season. For air handlers 15+ years old with rusted cabinets or cracked heat exchangers, we’ll show you video and give an honest repair-vs-replace call rather than patch a compromised unit. We’re not in the business of putting band-aids on equipment that’s already done.
Lennox Service Pricing in Miami
Most Lennox air duct cleaning jobs in Miami run between $450 and $900 for a full system, depending on the size of the home, the number of air handlers, and how much contamination has built up. A basic evaporator coil cleaning starts lower, and a full flex duct replacement on a larger home runs higher. The variables that drive cost in Miami specifically are attic access difficulty, the age and condition of existing flex duct, and whether mold remediation is required after an outage. Every estimate includes a video inspection so you see exactly what we see, and the written price is in your hands before work begins. Call (469) 972-3151 for a free estimate, and we’ll give you an exact number, not a teaser.

FAQs - Lennox Air Duct Cleaning in Miami
Miami’s year-round 75-80% relative humidity means your Lennox evaporator coil and drain pan stay wet between cycles, which accelerates mold colonization dramatically compared to drier cities. This is why Miami Dryer Vent Cleaning and full duct maintenance matter so much here. The condensation never fully evaporates, so biofilm builds up on the coil and blower surfaces, and that contamination then gets distributed through your ductwork every time the system runs. Call (469) 972-3151 and we’ll video-inspect the coil so you can see exactly what’s growing.
It’s usually both, and the only way to know for sure is a video inspection. In Miami’s post-WWII concrete block homes, flexible duct from the 1970s-90s often has a degraded vapor barrier that lets moisture into the liner, while the air handler cabinet gaskets have also failed and are pulling humid attic air into the supply path. We’ll trace the musty smell to its source and show you the footage before quoting any work.
Visible mold can appear on previously clean flex duct liner within 48-72 hours when indoor air sits at 85°F and 90%+ relative humidity, which is exactly what a Miami AC outage produces. We’ve documented this on Lennox systems in Brickell and Miami Beach after tropical storms. Call (469) 972-3151 for a free estimate if you’ve had an outage, and we’ll video-inspect before recommending any treatment.
Yes, and it happens faster than most people expect. Salt-laden air from the Atlantic and Biscayne Bay accelerates corrosion on galvanized metal duct components and Lennox air handler cabinets, creating rough, pitted surfaces that trap biofilm and dust. The corrosion isn’t just cosmetic; it creates a rough surface that keeps the contamination cycle going even after cleaning. Our video inspection shows the extent clearly.
Yes. Fan coil units in Miami high-rise condos are often original equipment from the 1960s-80s, and many have never been properly cleaned. We use negative-air extraction to pull contaminants out of the coil and blower without spreading them through the condo, and we replace saturated flex liner with OEM-equivalent material where needed. Call (469) 972-3151 and we’ll coordinate with your building’s access rules.
