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.
Lennox Air Duct Cleaning in Miami, CA | Morton’s Air Duct Cleaning
Air Duct Cleaning in Miami for a Lennox system typically runs $450-$850 for a full system on a single-family home, and most jobs take between three and five hours. We’re an independent Lennox service provider, not a factory-authorized dealer, which matters here because Miami’s humidity turns ordinary duct dust into a mold problem that generic cleaning won’t fix. Call us at (323) 918-4345 for a written estimate before anyone touches your system.
Why Miami Residents Choose Us for Lennox Service
Paul Adeyemi grew up in Inglewood and spent two decades working inside the walls and attics of homes across the Los Angeles basin before bringing that same hands-on approach to Miami’s Lennox systems. He learned ventilation mechanics at Los Angeles Trade-Technical College, and he’ll be the first to tell you that a Lennox air handler in Miami behaves differently than the same unit anywhere else in the country. The cabinet gaskets swell. The drain pans hold standing water for months. The flex duct inner liners bake and crack in attics that hit 140°F by late morning.
Our crews know every Lennox model family you’re likely to find in Miami-Dade, from the Dave Lennox Signature Collection down to older Merit series air handlers that have been running since the first Bush administration. We bring OEM Lennox gaskets and drain pans when they’re available, because aftermarket parts rarely fit the sloped-pan geometry correctly. Every visit includes shoe covers, drop cloths, a written price before work starts, and a photo of the clean-up before we leave. That’s the Cedarwell Care Promise, and it applies on every single job, not just the ones where someone asks.
For broader coverage details, our Miami service area page outlines the neighborhoods and building types we work in regularly, from single-family CBS homes to high-rise condos with fan-coil systems.
Common Lennox Air Duct Cleaning Problems We Solve in Miami
- Mold in Lennox sloped drain pans during Miami’s wet season. From May through October, outdoor humidity stays above 80% for weeks at a stretch. Your Lennox air handler’s drain pan never fully dries, and the cabinet’s negative pressure pulls spores straight into the supply stream. We clean and treat the pan, the cabinet interior, and the first few feet of duct on every job.
- Degraded flex duct inner liners in high-efficiency Lennox models. Miami attics routinely exceed 140°F, which bakes the inner liner of older Merit series flex ducts until micro-tears form. Humidity and organic debris collect in those tears, and microbial growth follows. We inspect liner integrity and recommend replacement where cleaning alone won’t restore airflow.
- Clogged Lennox evaporator coils with tight fin spacing. High-efficiency Lennox coils trap Miami’s airborne mold spores and pollen at a rate that surprises most homeowners. The result is reduced airflow and water blow-off that soaks the duct lining downstream. Evaporator coil cleaning is a standard part of our full system service here, not an add-on.
- Variable-speed blower motors running low during Miami’s mild winters. Signature series Lennox systems with variable-speed blowers often run at low speeds in December and January, when Miami’s cooling load drops. Duct interiors stay damp longer, and mold colonizes between cooling cycles. We address this with antimicrobial treatment and airflow verification.
- Embedded duct boots in older Miami CBS construction. In the 1950s-1980s concrete block homes of Hialeah, West Little Havana, and unincorporated Miami-Dade, original Lennox duct boots were often sealed directly into the concrete slab or interior walls. Full replacement isn’t practical. We clean and mastic-seal these boots in place, which keeps the system functional without tearing up floors.

Lennox Service in Miami: What Local Conditions Mean for Your Equipment
Here’s the reality we see week after week in the older CBS neighborhoods of Hialeah and West Little Havana: the original Lennox duct boots from the 1960s and 70s are sealed directly into the concrete slab or embedded in interior walls. You cannot pull them out without a jackhammer and a general contractor’s permit. That means full duct replacement, the standard fix in stick-frame markets up north, is off the table for most of these homes. The practical solution is a full cleaning cycle every two to three years, with mastic sealing at the boot connections and antimicrobial treatment on the coil and cabinet. This permanent-infrastructure reality shapes how we clean Lennox systems in Miami. We work non-destructively, we document everything with before-and-after photos, and we set homeowners up on a maintenance schedule that actually matches their house. In a 1965 CBS home in West Little Havana, our crew opened a Lennox Merit series air handler and found the flex duct inner liner collapsed and coated in black mold from years of attic heat and wet-season condensation. We performed a full system cleaning, applied antimicrobial treatment to the evaporator coil and cabinet, and mastic-sealed the embedded concrete duct boots that could not be replaced. The homeowner now schedules us every two years to keep the Lennox system mold-free without tearing up the slab.
Lennox Models & Products We Service in Miami
We work on every major Lennox line you’re likely to have in Miami, including the Dave Lennox Signature Collection (SL280V, SL297NV), the Elite Series (EL16XC1, EL18XCV), and the Merit Series (ML14XC1, ML17XC1), plus older Lennox CompleteHeat and air handler systems with insulated flexible duct runs. Our parts approach is straightforward: OEM Lennox gaskets, drain pans, and cabinet seals when they’re available, because aftermarket pieces miss the exact fit on Lennox’s sloped-pan geometry and can void performance. For flex duct and insulation, we use quality aftermarket materials rated for high-humidity environments. We’ll also tell you honestly when a Lennox air handler or coil is too compromised to clean. Sometimes replacement is the only safe option, and we’d rather lose the upsell than leave you with a system that’s still growing mold two months later.
For homeowners further up the coast, our Lennox service in Long Beach page covers the same level of model-specific detail for that market.
Lennox Service Pricing in Miami
Full system cleaning for a Lennox-equipped single-family home in Miami typically falls between $450 and $850, depending on the number of units, the accessibility of the ductwork, and whether antimicrobial treatment is needed. Homes with embedded concrete duct boots in Hialeah or West Little Havana often land at the higher end because sealing those boots takes time and care. Every estimate is free and written, and the price you sign is the price you pay. No per-vent surprises, no bait-and-switch. Before we start, let me show you exactly what we found and exactly what it will cost to fix it. Call (323) 918-4345 for a quote.

FAQs - Lennox Air Duct Cleaning in Miami
You usually need both. In a Miami high-rise, musty smells from a Lennox air handler almost always start with mold on the evaporator coil and in the cabinet, and then move into the duct run once spores spread. Cleaning just the coil leaves the contamination in the ducts, and the smell returns in a few weeks. We assess the full path and quote accordingly. Call (323) 918-4345 to have us take a look.
Heat plus humidity is the answer. Miami attics routinely exceed 140°F during the day, which degrades the inner liner of Lennox flex duct until micro-tears form. Then the wet season keeps outdoor humidity above 80% for months, and that moisture condenses inside the cool duct, feeding microbial growth in the tears. Cities without this combination simply don’t see the same failure rate. We see it constantly across Miami-Dade.
Yes, and this is one of the most common jobs we do in older Miami neighborhoods like Hialeah and West Little Havana. We clean the interior of the embedded boot, apply antimicrobial treatment, and mastic-seal the connections to prevent air leakage and moisture intrusion. Full replacement of these boots would require cutting into the slab, which isn’t practical or necessary in most cases.
We do when they need it. During a full system cleaning in Miami, we inspect the Lennox cabinet gaskets and sloped drain pan for wear, standing water, and mold, and we also check whether Miami Dryer Vent Cleaning is needed at the same time. If we find degradation, we replace with OEM Lennox parts when available. Aftermarket gaskets often miss the sloped-pan geometry and can void performance, so we don’t gamble with them.
Every two to three years in Miami, versus every three to five years in drier markets like Los Angeles or Phoenix. The difference is Miami’s year-round humidity and near-constant AC operation, which creates chronic condensation and mold pressure that dryer climates never see. For older CBS homes with embedded duct boots, the two-year cycle is especially important. Call (323) 918-4345 to schedule an inspection and get a written estimate.
