Lennox Air Duct Cleaning in South Miami, FL
Oasis Air Duct provides independent Lennox service across South Miami. We’re not affiliated with Lennox, and we don’t need to be: we’ve spent 13 years reading Lennox airflow tables, static-pressure specs, and the failure patterns of the brand’s air handlers and rooftop package units, and putting them back to factory-tight condition. That independent take is what makes our South Miami Lennox work different. No dealer script, no upsell – just what your equipment actually needs. Call (833) 384-3692 for a free estimate on Lennox air duct cleaning in South Miami.
Why South Miami Residents Choose Us for Lennox Service
Dave Kimball started Oasis Air Duct in 2013 after spending well over a decade in the trade, learning duct systems across South Florida’s residential and commercial properties. He trained in HVAC and mechanical systems at Miami Dade College’s North Campus, and that background is why we can diagnose a Lennox system without guessing. We know the Merit Series air conditioners, the Elite Series with variable-speed air handlers, the Signature Collection inverter systems paired with the SL280V furnace, and the rooftop package units that sit on South Miami’s 1950s – 1970s commercial buildings and ranch properties.
Our van carries professional-grade equipment, not improvised tools: Rotobrush rotary-brush systems, Nikro HEPA-filtered vacuums, and Abatement Technologies filtration for jobs that need remediation-level containment. When a Lennox installation calls for a replacement drain pan, blower motor mount, or cabinet gasket, we fit quality parts that match the equipment. Call (833) 384-3692 and we’ll set up a time to look at your system.

Common Lennox Air Duct Cleaning Problems We Solve in South Miami
- Return plenum leaks on older Lennox air handlers. The factory return plenum on many 1990s – 2000s Lennox units gets pulled apart by South Miami’s humidity cycle. In our experience the cabinet often gets taped rather than mastic-sealed, which dumps unconditioned attic air straight into the blower. We reseal properly and verify the seam holds.
- Evaporator coil fouling on Lennox variable-speed air handlers. The ECM blower in these units runs long low-speed cycles through South Miami’s nine-month cooling season, so the coil face loads with dust and biological growth faster than single-speed equipment would. Lennox’s tighter coil fin spacing traps it, which is why a coil cleaning is often the fix your system needs most.
- Condensate pan and cabinet corrosion on Lennox Merit units in attics. The factory pan and lower cabinet rust through when the drain line clogs during a wet South Miami summer. We open the cabinet, check whether the blower wheel and secondary heat exchanger surfaces are wicking that moisture, and clean what needs cleaning before it spreads.
- Flex duct collapse behind Lennox Signature rooftop package units. The short flex runs between the curb and the supply trunk in newer South Miami townhomes can kink and collapse. The SL28XCV’s variable-speed blower shows the symptom as high static pressure rather than an obvious airflow loss, so a static-pressure reading is what catches it.
- Original ductwork patched past its limit. Original fiberglass runs in South Miami’s 1950s – 1970s ranches often carry decades of duct tape that has peeled in the heat. We video-inspect the run, reseal the seams with mastic, and rebuild the sections that are beyond saving.
Lennox Service in South Miami: What Local Conditions Mean for Your Equipment
In the 1950s – 1970s concrete-block ranches around South Miami, original fiberglass duct runs are often buried in the slab or in low attic chases where previous owners patched them with duct tape. That tape fails in the summer heat. The result is that Lennox air handlers in these homes pull attic air and slab moisture through seams that aren’t visible until we run a video inspection. We were called to a 1962 concrete-block ranch off Red Road (SW 57th Avenue) where the owner’s Lennox Merit air handler was running nonstop and the electric bill had jumped. Our video inspection found the original fiberglass return chase under the slab had been re-taped three times over the decades, with the tape peeled back and the Lennox blower cabinet pulling hot attic air through the gap. We mastic-sealed the plenum, rebuilt the return run, and cleaned the evaporator coil. The system settled back to normal cycling within a day. That’s what 13 years of South Miami work teaches you: with Lennox equipment in this housing stock, the duct side is usually where the problem lives.
Lennox Models & Products We Service in South Miami
We service the Lennox product lines you’ll find in South Miami homes and small commercial buildings: Merit Series air conditioners (ML14XC1, ML16XC1) with matching air handlers, Elite Series systems (EL16XC1, EL18XCV) with variable-speed air handlers, Signature Collection inverter systems (SL28XCV, SL25KCV) paired with the SL280V furnace, and the rooftop package units (Model L and Model T series) common on 1950s – 1970s ranch and commercial properties. We choose quality parts that fit the equipment. On components like blower motor mounts, drain pans, and cabinet gaskets, we stock OEM Lennox parts that match. On commodity items – flex duct, mastic, insulation – we use quality aftermarket material that behaves the same. We’re an independent provider, not a Lennox dealer, and we’ll always tell you plainly whether a part needs the factory piece or not.

AfterLennox Service Pricing in South Miami
Pricing for Lennox duct work in South Miami depends on what we find once we’re on site. Whole-system cleaning on a typical single-story ranch is usually a modest, mid-range job. Duct sealing and return duct rebuilding add to that because they take more time and material. Evaporator coil cleaning on a variable-speed air handler is priced separately from the duct cleaning because it’s a different job with different access needs. Rooftop package unit work on newer townhomes carries its own estimate.
We set one flat price per system after a free estimate, and that price is written down before any work starts. No per-vent pricing, no surprise on the invoice. The estimate includes a video inspection of your ductwork, a static-pressure reading, and a written scope of what we’d do. Call (833) 384-3692 to schedule yours.

FAQs – Lennox Air Duct Cleaning in South Miami
Duct cleaning alone often won’t, but duct sealing and flex-run repair usually will. High static pressure on a Lennox variable-speed blower almost always traces to restricted or leaking ductwork, not to the blower itself. We measure static pressure before and after the work so you can see the change. Call (833) 384-3692 for an exact quote – estimates are free.
No, when the sealant is applied to correctly prepared surfaces. South Miami’s year-round humidity is exactly why we use mastic rather than tape and why we clean and prime the seam before sealing. Mastic cured properly holds through the wet season in an attic.
Clean it first, unless the coil is actually compromised. A fouled coil on a Lennox Signature inverter system can usually be restored with a proper coil cleaning. If the coil is leaking refrigerant or the fins are physically damaged, that’s when we tell you plainly it’s a replacement conversation.
Not the same work, but the same attention. The tight mechanical chases and short flex runs on newer South Miami townhomes fail differently than slab-buried fiberglass in the ranches. We inspect the flex runs between the curb and supply trunk, check static pressure at the rooftop package unit, and clean what the system actually needs.
Yes. Heat exchanger surfaces are inside the furnace cabinet, not the ductwork, and cleaning them is a separate procedure with its own safety checks. We inspect the heat exchanger whenever we’re servicing a Lennox furnace or air handler. If you’re not sure which service you need, call (833) 384-3692 – we’ll tell you straight.
