Why West Palm Beach Homeowners Choose Lennox Air Duct Cleaning
Linden Air Duct West Palm Beach provides independent Lennox air duct cleaning, repair, and Air Duct Cleaning services across West Palm Beach, from the 1920s Mediterranean Revival homes in El Cid to the high-rise condos along Flagler Drive. We are not Lennox-authorized, and that matters more than you might think: our recommendations come from what your ducts actually need, not a corporate service agreement. When we open a Lennox air handler in West Palm Beach, we know what the salt air and 80% humidity have been doing to it since March. Call (728) 231-8154 for a written quote before any work begins.
We service every major Lennox line: Elite Series air handlers like the CBX32MV, Signature Collection variable-speed units like the SLP98V and XC25, Merit Series equipment, and Healthy Climate filtration including the PureAir cabinet and HCWB3 media filters. Our crew has spent years inside these systems in West Palm Beach specifically, where long cooling seasons and corrosive ocean air create failure patterns you will not find in a Lennox owner’s manual, and we also provide Lennox service in West Palm Beach. The manual was not written for a house three blocks from the Intracoastal.
Why Trust Linden Air Duct West Palm Beach for Your Lennox Air Duct Cleaning?
Marcus Veale, our owner, grew up working on mechanical systems in Los Angeles and completed his vocational HVAC training at Los Angeles Trade-Technical College before moving into air duct work full time. He has been servicing homes across West Palm Beach for years, including plenty of jobs in Flamingo Park where the original galvanized ducts date back to before central air was standard. His habit of showing up on time, explaining what he found before he starts, and not padding the invoice with unnecessary work is the reason much of our business comes from repeat customers and neighbor referrals.
For Lennox systems, that experience translates into something practical: we know which filter cabinets leak return air on which models, which flex duct runs sag first in a hot Florida attic, and where the evaporator coil sits in relation to the plenum so we can clean it without pulling the entire air handler apart. Every technician who arrives at your West Palm Beach door is background-checked, identity-verified, and photo-badged under the Threshold Standard. We send you their name and photo before the visit. They show a photo ID at the door. That is how we have operated since 2004, and we do not make exceptions.
Our pricing follows the same logic. You get a written price before any work starts, every time. No per-vent games. No surprise invoice at the end. The number we quote is the number you pay, and every repair carries a written guarantee with a free second visit if the repair does not hold. If we would not leave it in our own ceiling, we are not leaving it in yours.

Common Lennox Air Duct Cleaning Problems We Fix in West Palm Beach
- Flex duct sagging and kinking at the AHU plenum. On Lennox Elite and Merit air handlers, the supply plenum connection is often a short flex collar that kinks when installers cut it too tight. In a West Palm Beach attic pushing 130 degrees in July, that flex softens and collapses further, restricting airflow and forcing the blower to work harder. We find this on at least one in three Lennox systems we open. The fix is rerouting with metal elbows and resealing the plenum collar with mastic rated for South Florida humidity, not just tightening the zip tie.
- Fiberglass duct board delamination from condensation. Variable-speed Lennox systems like the SLP98V run long, low-stage cooling cycles to control humidity. That is good for comfort, but it means the duct board inside the plenum stays cold and wet for hours at a time. Over one or two West Palm Beach summers, the fiberglass facing starts to separate and shed particles into the airstream. We see this frequently on systems where the duct board was never sealed with a proper vapor barrier. We inspect every plenum with a camera before recommending cleaning so we know whether the ducts are shedding fiberglass or just accumulated dust.
- Return-air leakage at the Lennox filter cabinet. The factory filter cabinet on many Lennox units, especially the CBX32MV series, has a 1- to 2-inch gap around the access door that never gets sealed at install. In a humid West Palm Beach home, that gap pulls attic air directly into the system, bypassing the filter entirely and loading the evaporator coil with dust and mold spores. Every Lennox cleaning we do includes a check of the filter cabinet seal. When we find leakage, we seal it. It is the single most common reason a Lennox coil looks like a carpet after two years.
- Dryer vent lint packing in slab-duct Lennox homes. Many West Palm Beach ranch homes built in the 1950s and 1960s have slab-duct HVAC systems with long lateral duct runs under the concrete. The dryer vent often ties into the same chase or shares wall space with the supply ducts. When lint bypasses the dryer’s own trap, it migrates into the ducts and packs into the low spots, where West Palm Beach’s humidity turns it into a damp, fibrous mat. That mat is exactly what mold wants to grow on. Our dryer vent cleaning addresses the source, and our negative-pressure duct extraction removes what has already made it into the system.
- Rusting galvanized ducts in El Cid and Flamingo Park. Historic West Palm Beach homes still have original galvanized steel supply ducts, and after seventy or eighty years of salt-laden ocean air, the seams are rusting. Homeowners notice a musty, metallic smell when the AC kicks on and sometimes see fine rust-colored particles on furniture near the vents. We clean what can be cleaned, but when the galvanized duct has rusted through, cleaning is not enough. We quote the replacement honestly and show you the camera footage before you spend a dollar.
Lennox Parts & Our Repair-vs-Replace Approach
Our stance on parts is straightforward. Where Lennox specifies a particular component, like the OEM MERV-16 filter in a PureAir cabinet or a specific coil cleaner for the aluminum evaporator, we use the OEM part. No argument there. But for duct sealing, mastic, flex duct, and grille replacement, we use commercial-grade aftermarket materials selected for South Florida conditions: UV-stable flex, mastic rated for 90% humidity, and metal collars that do not corrode in salt air. Lennox does not manufacture duct mastic, and the aftermarket products we use are the same ones high-end mechanical contractors specify on new construction in West Palm Beach.
The repair-versus-replace decision follows a simple rule. When an older Lennox air handler has a corroded drain pan or a failing ECM blower motor but the ducts are sound, we recommend the repair. Most West Palm Beach duct systems suffer from leakage and contamination, not structural failure, and a full replacement is thousands of dollars you may not need to spend. We recommend full duct replacement only when camera inspection shows leakage above 25%, the duct board is delaminating throughout, or mold is present in the ductwork itself. We will show you the footage and walk you through the numbers before you commit to anything. Call (728) 231-8154 for an honest assessment.
Our Lennox Service Process – Step by Step
- 1
Diagnosis with video inspection. Before we clean anything, we run a camera through your supply and return ducts, and we open the air handler to inspect the coil, blower, and filter cabinet. For Lennox systems in West Palm Beach, we are specifically looking for return leaks at the filter cabinet, flex duct collapse at the plenum, and rust on the coil pan. You see the footage before we recommend a single service.
- 2
Repair and prep before cleaning. If we find failed flex duct, leaky plenum collars, or a bypassing filter cabinet, we fix those first. Cleaning a duct system that is still leaking is a waste of your money. On Lennox CBX32MV air handlers, this usually means resealing the plenum with mastic and replacing the flex collars with metal elbows where needed.
- 3
Negative-pressure extraction with HEPA filtration. We connect professional-grade Rotobrush or Nikro equipment to create negative pressure in the duct system, then agitate the interior walls to release accumulated dust, lint, and debris. The HEPA-filtered negative air machine captures what we dislodge. If we are cleaning a Lennox system with a Healthy Climate ventilation damper, we account for that damper’s position so we do not pressurize the outdoor air intake.
- 4
Evaporator coil cleaning and filtration check. A clogged Lennox coil is a symptom of duct leakage, so we close the loop by cleaning the coil after the ducts are sealed and extracted. We also check the filter cabinet seal and, on Healthy Climate systems, inspect the PureAir cabinet for media saturation.
- 5
Testing and documentation. We measure static pressure before and after on every Lennox job. A healthy system should fall between 0.4 and 0.6 inches of water column. We show you the numbers, and we leave you with before-and-after photos of your own ducts. Every repair carries a written 365-day guarantee. If a covered repair fails, we return at no charge and make it right.

FAQs – Lennox Air Duct Cleaning Service in West Palm Beach
That dust is usually coming from inside the duct system, not the air handler itself. Variable-speed Lennox blowers like the one in the SLP98V run at low speed for long cycles, which builds less velocity than older single-speed units. Dust that settles in the ducts during the off cycle gets stirred up when the blower ramps to high stage, and it blows out the nearest registers before it has a chance to reach the filter. The real fix is cleaning the ducts and sealing the return side so unfiltered attic air is not being pulled in. Call (728) 231-8154 for a video inspection and we will show you exactly where the dust is originating.
Yes. The PureAir cabinet is mounted at the air handler, and our cleaning process uses negative pressure on the duct runs and return, not high-pressure air blasted through the filtration cabinet. We also check the PureAir filter media itself. In West Palm Beach humidity, the activated-carbon layer in the PureAir media can saturate and become a source of odor rather than a filter of it. If the media is loaded, we will tell you and recommend a replacement filter, which is an OEM part we keep in stock.
Sometimes. A frozen Lennox evaporator coil usually means low airflow across the coil, low refrigerant charge, or a stuck TXV. But the airflow piece is often a duct problem: collapsed flex at the plenum, a clogged filter, or a heavily loaded coil from years of return-air bypass. Before you call an HVAC company to recharge the refrigerant, have the static pressure checked and the coil inspected. We have fixed frozen-coil complaints on West Palm Beach Lennox systems where the only real issue was a filter cabinet pulling attic air and a coil caked with lint. Call (728) 231-8154 and we can rule the duct and coil side out first.
Every three to five years in West Palm Beach, and closer to three if you live near the ocean or have pets. The Healthy Climate ventilation damper opens to bring outdoor air into the home, which is good for indoor air quality but also pulls in salt-laden, humid coastal air. That air deposits fine salt particles in the ducts, and the salt attracts and holds moisture, which accelerates dust accumulation. We recommend an annual video inspection so you can see the actual buildup instead of cleaning on a blind schedule. Call (728) 231-8154 to schedule an inspection; if the ducts are clean, we will tell you that too.
We use commercial-grade aftermarket flex duct rated for high-humidity attics and UV exposure. Lennox does not manufacture its own flex duct; the factory uses the same aftermarket suppliers available to independent contractors. What matters is the spec: insulated R-6 or R-8 flex with a reinforced vapor barrier and metal collars that will not rust. We install what will hold up in a West Palm Beach attic for fifteen years, not whatever matches the original sticker. Mastic sealing at every joint is included on every flex replacement.
For a typical single-family home in West Palm Beach with one Lennox air handler and 10 to 15 runs, expect $450 to $850 for a full supply and return duct cleaning with HEPA negative air, depending on system size, access, and whether you add evaporator coil cleaning or duct sealing; we also offer Boynton Beach Lennox service. Condos with long, complex duct runs typically fall between $500 and $1,000. You get a written price before any work begins, and that price does not change. Call (728) 231-8154 for a free estimate and we will give you a firm number for your specific Lennox system.
