Every job gets a written price up front, and every job carries our 365-Day Done Right Promise in writing.
Why Fort Lauderdale Residents Choose Us for Lennox Service
Lennox builds quality equipment, but Fort Lauderdale doesn’t do it any favors. Constant humidity forces condenser coils to work harder, which pulls more moisture through the system. Salt air off the Atlantic accelerates corrosion on galvanized duct sections and evaporator coils. We’ve worked on Lennox systems in hundreds of homes across this city, and we know which failure points show up most often in coastal properties versus inland neighborhoods near Plantation or Sunrise.
Roy Castellanos, owner at Hollis Air Duct Fort Lauderdale, picked up his trade fundamentals at Los Angeles Trade-Technical College before spending the better part of two decades doing HVAC and duct work across South Florida. He and the crew have cleaned Lennox systems in homes a few blocks from Las Olas Boulevard and in commercial buildings closer to the Port Everglades corridor. Roy’s straight with people. He’ll tell you what your ductwork actually needs, not what pads an invoice. Clean ducts move air. Everything else is just noise.
We use OEM Lennox replacement parts when it matters for airflow and filtration. When OEM lead times stretch out, we recommend quality aftermarket components instead of letting your system sit. The decision is always yours, with a clear explanation either way.

Common Lennox Air Duct Cleaning Problems We Solve in Fort Lauderdale
- Mold growth inside insulated flex ducts. Lennox systems in Fort Lauderdale run for months in high-humidity mode. The interior liner of flex ducts collects dust and organic matter, and when condensation forms inside, mold follows. You’ll notice it first as a sour smell when the blower kicks on. We clean the full duct run and treat the liner to stop regrowth.
- Corrosion on Lennox evaporator coils from salt-laden air. Condos and homes east of Federal Highway get hit hardest. Salt particles enter through dryer vents, balcony doors, and fresh air intakes. They settle on the coil, and once pitting starts, it spreads. A corroded coil doesn’t transfer heat properly, so your compressor runs longer and your humidity climbs. We clean coils with commercial-grade solutions safe for Lennox aluminum fins.
- Clogged condensate lines and drain pans. South Florida’s wet season puts steady moisture across the coil, and that water carries dust and biological growth into the drain line. A blocked line overflows the pan, and now you’ve got water damage around the air handler. We clear the line, clean the pan, and recommend a drain treatment schedule for Fort Lauderdale homes.
- Dust and debris buildup on older Lennox air handlers. Many Fort Lauderdale homes built in the 1950s through 1970s still run their original or early-replacement Lennox blower cabinets. Blower wheels pack with lint and drywall dust, which cuts airflow and forces the motor to overwork. We pull and clean the blower assembly as part of every full duct cleaning.
- Salt corrosion mimicking a persistent “ocean smell.” In beachfront and Intracoastal high-rises, salt spray works into common ventilation ductwork and begins eating the zinc coating on galvanized sections. Residents often think the smell is just the ocean. It’s not. It’s corroding metal and trapped sea salt inside the ducts. We identify affected runs and seal or replace them as needed.
Lennox Service in Fort Lauderdale: What Local Conditions Mean for Your Equipment
Here’s something specific to Fort Lauderdale that doesn’t show up the same way in Pompano Beach or Plantation. The high-rise condos lining the Intracoastal and the beach share common duct risers that run floor to floor. Salt spray from the ocean enters these risers through Fort Lauderdale Dryer Vent Cleaning openings and balcony doors, then travels through the shared duct structure. On Lennox systems with galvanized ductwork, that salt causes zinc corrosion that reads as a musty, metallic odor. Residents call it an ocean smell. It isn’t. It’s the sound and smell of ductwork degrading from the inside. Our crews have pulled apart riser sections in buildings east of Oakland Park Boulevard where the galvanized coating was actively flaking after a decade of salt exposure. We clean what’s salvageable, seal what we can, and replace what’s too far gone. For Lennox owners in these buildings, duct cleaning isn’t just about dust. It’s about stopping corrosion before it eats through the metal.
Lennox Models & Products We Service in Fort Lauderdale
We service every Lennox residential line you’re likely to find in a Fort Lauderdale home or condo: the Elite Series, the Merit Series, the Signature Collection, and the Dave Lennox Signature Collection. That covers everything from budget-conscious builder-grade Merit air handlers in 1960s and 1970s ranch homes to high-efficiency Signature Collection systems in waterfront high-rises. Most parts we use are OEM Lennox, sourced to keep airflow and filtration performance where the manufacturer intended. When a coastal corrosion problem needs a part with a long OEM lead time, we’ll offer a quality aftermarket alternative and explain the trade-off before you spend a dollar. On older Lennox systems where a few duct sections are badly corroded, we usually recommend targeted repair and sealing over full replacement. It’s less disruptive and a lot less expensive, and the sealed sections hold up better in Fort Lauderdale humidity.

Duct sealing runs $800 to $1,800 for most homes, determined by accessible duct footage and how many joints and seams need mastic work.

FAQs – Lennox Air Duct Cleaning in Fort Lauderdale
Every 2 to 3 years if you’re within a mile of the beach. Salt air and high humidity accelerate corrosion and mold growth inside ducts at roughly double the rate of inland locations. Condos with shared duct risers need it even more often because you’re dealing with building-wide air movement, not just your unit. Call (754) 354-3644 and we’ll assess your building’s specific setup.
It does, in two ways. First, older duct runs in homes from that era were often undersized to begin with, so any buildup of dust and debris cuts airflow noticeably. Second, the original Lennox air handlers from that period have blower cabinets and coils that collect decades of grime. We clean them thoroughly and usually recommend sealing accessible duct sections while we’re there. The difference in system noise and airflow after cleaning is significant.
Yes. We use Rotobrush rotary brush systems and Nikro negative-air machines with adjustable pressure settings. On Lennox flex duct runs, we dial the brush speed back and use flexible rodding that won’t tear the inner liner. The insulation stays intact. It matters more in Fort Lauderdale because any tear in the liner lets humid air reach the fiberglass, and that’s exactly how mold gets a foothold.
Pitting corrosion on the aluminum evaporator coil fins. Salt particles land on the coil and, mixed with constant condensation, create localized corrosion that reduces heat transfer. Once pitting takes hold, the coil degrades steadily. We clean coils with solutions formulated for Lennox fins, but on badly pitted coils we’ll be honest: replacement is the real fix. We’ll tell you before you spend money on a cleaning that won’t hold.
Almost always. Shared risers in Fort Lauderdale condos leak at every transition and joint, which means you’re paying to condition air that escapes into a chase or a neighbor’s unit. Mastic sealing is the single best thing you can do for airflow and efficiency in a high-rise Lennox system. We’ve seen sealed risers improve airflow by as much as 30% in older buildings.
