We’re not a manufacturer affiliate. We’re an independent service provider with deep Lennox familiarity. Roy Castellanos, our owner, has been running duct crews in Miami for over a decade, including jobs through Brickell high-rises and older Coral Gables homes. He’d rather explain a price once than defend a bill twice. Visit our Lennox sales & service page to see the full scope of what we handle.

Miami-Specific Lennox Knowledge | Hollis Air Duct Miami

Quick answer: Lennox air duct cleaning in Miami typically runs $450 – $900 for a full system, depending on condo access and duct condition. Salt-corrosion sealing adds $200 – $400. Most jobs finish in 3 – 6 hours, and we leave before-and-after photos so you can see the work was actually done.

Miami’s climate doesn’t just dirty ducts. It attacks them. Condensation forms inside duct runs because the temperature differential between conditioned air and 90-degree attic or chase air is so extreme. That moisture feeds mold on Lennox Healthy Climate media filters and duct surfaces. Salt in the air settles into that moisture, corroding seams on older Lennox Elite metal ducts. We clean, seal, and document everything. You get a written price before we start, and every job is covered by our 365-Day Done Right Promise: if it fails within a year, we return at no charge.

Our technicians are background-checked and uniformed. Our phones are answered by a live person around the clock. And we work with the same equipment commercial crews use: Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman.

Why Miami Residents Choose Us for Lennox Service

Most duct cleaning companies in Miami will clean any duct, but few understand Lennox systems or offer Miami Dryer Vent Cleaning specifically. We do. Our techs know how Lennox XC/XP series evaporator coils collect salt-laden dust in Miami’s sea breeze, and how that reduces heat transfer and creates that musty smell you can’t get rid of. We know Lennox Merit flex duct sagging in high-rise closets, and we know how to access the return side through a small panel in the hallway, coordinating with building management when needed.

Roy Castellanos grew up in Los Angeles and learned trade fundamentals at Los Angeles Trade-Technical College before spending years working HVAC and duct systems across Southern California. The humidity down here taught him things no classroom covers. The Garrison Code governs every job: arrive inside the window, price in writing, complete the work by the book, leave the site clean. If you can’t explain the job plainly, you probably shouldn’t be doing it.

We stock OEM-compatible filters and coatings for fast Miami turnaround. When warranty or performance is at stake, we use OEM Lennox parts. For duct sealing and flex repair, we often recommend industrial-grade mastic and UV-stabilized flex that cost less and last longer in humid, outdoor-rated environments. We don’t push part replacement when proper cleaning and sealing will restore airflow. We’ll tell you honestly if your Lennox ducts are worth saving.

Common Lennox Air Duct Cleaning Problems We Solve in Miami

• Mold on Lennox Healthy Climate media filters and duct surfaces. Miami’s high humidity causes condensation inside ducts, and that moisture feeds mold growth on the media filter and the duct walls. We remove the contamination with negative-air cleaning and HEPA filtration, then address the moisture source so it doesn’t come back next summer.
• Salt-air corrosion of metal duct seams and registers on older Lennox Elite installs. Decades of salt breeze work through steel ducts from the outside in. We scope the system, identify rusted-through seams, and seal them with mastic to stop attic dust infiltration and air loss.
• Flex duct degradation in Lennox Merit systems in high-rise condos. Where the air handler sits in a small closet and the return runs through a shared chase, flex duct sags and collapses. We access through the hallway panel or dropped ceiling and repair or re-run the affected section, no drywall demolition needed.
• Salt-laden dust on Lennox XC/XP evaporator coils. Sea breeze carries salt particles that bond to the coil, reducing heat transfer and causing musty odors. We clean the coil with professional-grade solutions and document the before-and-after with photos.
• Attic dust infiltration through rusted duct seams in older Coral Gables homes. Original 1950s – 1970s ductwork often has rusted seams that pull in attic insulation and dust. We seal the seams with mastic and clean the entire system so your Lennox unit isn’t circulating fifty years of attic debris.

Lennox Service in Miami: What Local Conditions Mean for Your Equipment

In Miami’s Brickell and Edgewater high-rises, many Lennox air handlers are installed in closets with the return duct running through a shared chase. To clean the return side, we often must coordinate with building management and access the ductwork through a small access panel in the hallway or above the dropped ceiling. That’s something you’d never encounter in a single-family home in Kendall or Hialeah.

This changes how the job gets done. You can’t wheel a large negative-air machine through a condo tower’s service elevator without scheduling it. You can’t run hoses through common hallways without approval. You need a crew that’s worked with Miami building managers, understands access protocols, and arrives with the right equipment for tight closet ceilings. We’ve done this hundreds of times. It’s not a challenge; it’s the job.

For Lennox owners specifically, the shared chase means your return duct may be pulling air from spaces outside your unit if the chase isn’t sealed properly. One unit’s cooking odors or construction dust can end up in your air stream. We inspect the return path under negative pressure and seal leaks so your Lennox conditions only your air, not the building’s.

Lennox Models & Products We Service in Miami

We service all Lennox model families found in Miami, including the XC/XP series (XC25, XP20), Merit series, Elite series, and Lennox Healthy Climate filtration systems. Our approach is straightforward: use OEM Lennox filters and coatings where warranty or performance is at stake, but recommend industrial-grade mastic and UV-stabilized flex for sealing and repair work because they hold up better in humid, salty air. We keep common Lennox-compatible parts stocked for fast Miami turnaround, and we never push replacement when cleaning and sealing will restore proper airflow. If localized re-running makes more sense, we’ll tell you that too.
