Lennox Air Duct Cleaning in Miami Gardens, FL | Hollis Air Duct Miami
We provide Air Duct Cleaning in Miami Gardens for independent Lennox systems across FL, and the one factor that separates our work here is how we handle what decades of subtropical humidity does to Lennox ductwork. Most homes we open up in Miami Gardens show some form of humidity-driven mold or degraded liner. We clean it, seal it, and document it. Call (850) 660-3272 for a written quote.
Our techs work on Lennox equipment daily, from older Merit Series air conditioners to current Elite Series air handlers. We’re not a manufacturer affiliate. We’re a local crew that understands how Lennox systems behave in Miami Gardens’ specific housing stock, and we price every job in writing before touching a vent.
Why Miami Gardens Residents Choose Us for Lennox Service
Most duct cleaning companies will clean any brand. Few can tell you why a Lennox Elite air handler in a 1960s concrete-block ranch needs different treatment than the same unit in a newer Doral townhome. We can. Miami Gardens has a particular mix of mid-century homes with original flex duct and newer multi-family construction with shared risers. That combination requires a crew that knows Lennox airflow specs and this city’s duct realities.
Roy Castellanos, our owner, learned the trade at Los Angeles Trade-Technical College and has run HVAC and duct crews in South Florida for well over a decade. Work in Brickell high-rises and older Coral Gables homes taught him what humidity does to ductwork, and those lessons carry straight into every Miami Gardens job we take. We use Lennox OEM filters where they’re the right call and premium aftermarket antimicrobial coatings and mastic sealants where they outperform OEM. You get a straight explanation either way.
We’re part of the Lennox sales & service support network for this region, but independently owned and operated under The Garrison Standard: arrive inside the quoted window, put the price in writing, do the work by the book, and leave the site clean. If it’s not done right, our 365-Day Done Right Promise covers the repair in writing for a full year.

Common Lennox Air Duct Cleaning Problems We Solve in Miami Gardens
- Mold colonization on evaporator coils and in supply plenums. Miami Gardens’ year-round humidity keeps coils damp long after the AC cycles off. On Lennox systems, that dampness feeds mold in the supply plenum, which then distributes spores through your vents. We treat the coil with an antimicrobial spray and clean the full supply side.
- Collapsed or degraded flex duct on mid-century Lennox installations. Homes built in the 1950s through 1970s around Miami Gardens often have original flex duct that’s been baking in attic heat for decades. The inner liner breaks down, airflow drops, and particles enter living spaces. We repair or replace the failed sections.
- Biological growth inside insulated return ducts. Condensation forms where return ducts pass through unconditioned spaces. In Miami Gardens’ humidity, that moisture never fully dries, and the insulated liner becomes a breeding ground. We remove the contamination and seal the duct to prevent recurrence.
- Post-hurricane debris clogging the blower wheel and heat exchanger surfaces. After a storm, fine dust and debris get pulled into the return side and coat the blower wheel. A clogged Lennox blower moves less air and works harder. We clear it and verify airflow before we finish.
- Friable fiberglass liner shedding particles. This is a Miami Gardens-specific problem we see constantly west of NW 27th Avenue. When 1970s fiberglass liner breaks down, it releases glass fibers into the airstream. Cleaning alone won’t fix it. We remove the liner and reseal the metal duct.
Lennox Service in Miami Gardens: What Local Conditions Mean for Your Equipment
In the older sections of Miami Gardens west of NW 27th Avenue, our techs routinely open return air chases and find 1970s fiberglass duct liner that has collapsed or turned friable. This is not a cleaning problem. It’s a material failure. The liner sheds glass particles into the airstream, and no amount of brushing will restore it. Lennox systems in these homes often still have their original ductwork, which means the liner was installed decades before today’s humidity levels and filtration standards. The fix is targeted removal of the degraded liner, mechanical cleaning of the metal duct beneath, and re-sealing with mastic. On a ranch home near NW 183rd Street and NW 27th Avenue, our tech opened a return air chase on a Lennox Elite air handler and found the fiberglass liner had collapsed onto the blower inlet. We removed the degraded liner, sealed the metal duct with mastic, and treated the coil with an antimicrobial spray to restore proper airflow. That kind of find is common here and rare in nearby cities with newer housing stock.
This is why a generic duct cleaning quote for Miami Gardens misses the point. If your Lennox system sits in a home built before 1980, the question isn’t whether the ducts are dirty. It’s whether the liner is still intact. We inspect for that before we clean, because cleaning a duct with failed liner just stirs up more particles.
Lennox Models & Products We Service in Miami Gardens
We work on Lennox Elite Series air handlers, Merit Series air conditioners, and Signature Collection units including the SLP98V furnace and XC25 air conditioner. We also clean and service Lennox Healthy Climate filtration systems, including media cabinets and UV lights where installed. Our default is OEM filters and OEM replacement flex duct when replacement is the right path. For antimicrobial coatings and duct sealants, we use premium aftermarket products that match or exceed OEM performance specs, and we’ll tell you why when we quote the job.
We keep common Lennox filter sizes and flex duct sections stocked for faster Miami Gardens turnaround. If your system needs a liner removal or coil treatment, we schedule it in one visit whenever possible.

FAQs – Lennox Air Duct Cleaning in Miami Gardens
Because mold in Miami Gardens ductwork is driven by humidity, not just filtration. Your filter catches particulates, but it can’t stop condensation from forming inside insulated ducts and on the evaporator coil. When that moisture never fully dries, mold grows regardless of filter discipline. The fix is cleaning the affected surfaces and treating them with an antimicrobial product designed for HVAC use. Call (850) 660-3272 and we’ll inspect the coil and supply plenum to confirm the source.
Yes. We clean the media cabinet, replace filters where needed, and wipe down UV lamp surfaces if installed. A Healthy Climate system only works as intended if the air moving through it is clean on both sides, so we treat the filtration unit as part of the full duct cleaning, not an add-on.
Usually both, and in Miami Gardens the rain makes it worse. The smell typically comes from microbial growth on the coil or in the supply plenum, where post-rain humidity spikes linger. The ducts then carry that odor through the house. We clean and treat the coil, the plenum, and the supply ducts together, because treating one without the other just moves the problem.
When the flex duct’s inner liner has degraded or collapsed, yes. Cleaning won’t restore airflow or stop particle shedding. In 1950s-70s Miami Gardens homes, we often find flex duct that’s beyond its service life. We’ll show you photos and give you a replacement price only when replacement is the honest call. Many systems just need cleaning. We won’t sell you a replacement you don’t need.
Shared risers require coordination with the building or HOA, and we’re set up for that. We clean the portions of the riser that serve your unit and document the work with before-and-after photos. If the riser has common-area access limitations, we’ll tell you upfront what we can reach and what requires building-side action. Call (850) 660-3272 and we’ll walk you through the specific logistics for your building.
