AfterLennox Air Duct Cleaning in Jacksonville, NY | CleanRun Air Duct Cleaning
We provide independent Lennox air duct cleaning, repair, and coil service across Jacksonville, backed by a written price before any work starts and a documented photo record when we leave. The reason our Lennox work here is different comes down to one local factor: this city’s St. Johns River basin keeps indoor humidity elevated nearly year-round, which means Lennox duct systems in Jacksonville accumulate biological growth and liner debris at a rate we rarely see 20 miles inland. If you own a Lennox system in Jacksonville, you’re dealing with a set of conditions most national cleaning companies don’t plan for.
Tomas Reyes, our owner and lead technician, spent years tracing Lennox air handlers and flex duct through slab-on-grade homes across Jacksonville’s post-consolidation suburbs. We know which failure modes show up in attic-mounted Lennox Elite and Merit systems here, and we know what it takes to fix them. Call us at (806) 606-6902 for a written estimate based on what our camera actually finds.
Why Jacksonville Residents Choose Us for Lennox Service
CleanRun Air Duct Cleaning has served Jacksonville since 2013, and we’ve built our entire process around one question: can the customer verify the work? Every job starts with a camera inspection, every duct run is photographed before and after, and every price is written down before a single panel comes off. That’s Haven Standard Clause 1, and we don’t make exceptions.
We’re an independent Lennox service provider, not a manufacturer affiliate or authorized dealer. That matters because our loyalty is to what the camera shows, not to a brand’s recommended replacement schedule. When a Lennox flex run has collapsed in a 130-degree attic, we’ll tell you. When the liner has shredded and you’ve been breathing fiberglass dust, we’ll show you the photo before we discuss remediation.
Tomas grew up in Woodside, Queens, a few blocks from the elevated 7 train, in a building whose ductwork hadn’t been touched since the Carter administration. He confirmed that himself once he got into the trade. After completing HVAC coursework at Queensborough Community College and working residential and commercial duct systems across all five boroughs, he brought the same approach to Jacksonville: camera first, written scope second, no work until the customer has seen what’s inside. Visit our Lennox sales & service page for more on how we approach the Lennox brand specifically.
Common Lennox Air Duct Cleaning Problems We Solve in Jacksonville
- Shredded flex duct liners in 130°F+ attics. Lennox flex ducts installed during the 1970s and 1980s in Jacksonville’s slab-on-grade homes have spent decades baking in attic heat that regularly exceeds 130°F. The inner Mylar-and-fiberglass liner degrades and sheds into the airstream. We pulled a 1979 run from an Arlington attic that measured 137°F at 2 p.m. The liner had disintegrated into fiberglass dust blowing through every register.
- Evaporator coil biofilm from St. Johns River humidity. Lennox air handlers in attic installations collect microbial buildup on the coil when Jacksonville’s persistent humidity prevents drying between cooling cycles. With roughly 10 months of near-continuous AC operation, the coil rarely gets a chance to dry. The result is reduced airflow and a chronic musty smell that air filter changes never fix.
- Disconnected or sagging flex runs in attic spaces. The outer jacket on aging Lennox flex duct degrades under attic heat, causing runs to sag, kink, or separate at the plenum connection. Jacksonville’s humid air infiltrates those gaps, condensing inside the duct and creating conditions for mold colonization that make this a remediation issue as much as a cleaning one.
- Uneven airflow in split-level post-consolidation homes. Lennox systems paired with aftermarket or mismatched flex duct often show temperature stratification between floors. In Jacksonville’s Westside and Southside split-levels, we regularly find the upstairs running 8 to 10 degrees warmer because the duct runs serving that level have collapsed or disconnected.
- “Dirty sock” odor from microbial growth on flex duct interiors. The combination of extreme attic heat and river-basin moisture means Jacksonville Lennox systems develop odor problems faster than systems in Orlando or Atlanta. The biofilm doesn’t dry, the attic heat bakes it, and the smell recirculates through the living space every time the Merit or Elite series air handler cycles on.
BeforeAfterLennox Service in Jacksonville: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic duct cleaning page: Jacksonville’s St. Johns River basin creates a ground-level humidity plume that does not exist even 20 miles inland. The river is wide and slow-moving, and it runs directly through the heart of the city. When that river-basin moisture infiltrates aging Lennox flex duct seams during the long cooling season, condensation inside the ducts rarely has a chance to fully dry. After less than two years of continuous AC runtime, Lennox duct runs in Jacksonville collect microbial biofilm on coil surfaces and flex duct liners on a timeline that doesn’t apply the same way in Orlando or Atlanta.
Add Jacksonville’s post-1968 city-county consolidation building boom to that equation, and you get enormous tracts of slab-on-grade homes with attic-mounted Lennox air handlers and flex ductwork now 35 to 50 years old. Those attics regularly exceed 130°F in summer, and the heat accelerates liner degradation while the river humidity prevents moisture from ever fully clearing the system. In Arlington and Wesconnett, our technicians routinely pull original late-1970s Lennox flex duct that’s been running essentially nonstop for 40-plus years. The inner liner has shredded. It’s blowing into the living spaces. The photography from those jobs tells the whole story.
“The photo tells you what’s in there. Everything else is just paperwork.” That’s how Tomas puts it, and it’s why we include a documented photo record of every duct run on every Jacksonville job. You’ll see what the camera saw, before and after, regardless of what our written scope said.

Lennox Models & Products We Service in Jacksonville
We service the full Lennox residential lineup across Jacksonville, including the Dave Lennox Signature Collection (XC25, SLP98V), the Elite Series (EL296V, EL18XCV), and the Merit Series (ML14XC1, ML180). We also work on Lennox Healthy Climate ventilation products like the PureAir S and HC16 air purification systems when duct cleaning involves sanitizing or air quality remediation.
On parts, our approach is specific: we source genuine Lennox OEM components when a repair needs the factory-spec fit, which matters most for coil compatibility and air handler connections. For duct sealing, insulation upgrades, and general ductwork restoration, we use high-grade aftermarket materials that outperform the original flex in Jacksonville’s attic heat and humidity. That’s not a cost-cutting decision. It’s a product decision. Reinforced R-8 flex with a properly sealed mastic connection lasts longer in a 137°F Jacksonville attic than the factory material from 1979 ever did.
We’re also honest about when full duct replacement makes more sense than repeated repairs on collapsed or shredded Lennox runs. You’ll get that recommendation in writing, with the price attached, before you decide anything.
Lennox Service Pricing in Jacksonville
Air duct cleaning for a typical single-system Jacksonville home runs between $450 and $900, depending on the number of duct runs, the condition of the flex, and whether evaporator coil cleaning is included. Duct repair or replacement work typically adds $250 to $750 per run, depending on access and materials. A full Lennox duct system replacement in a slab-on-grade Jacksonville home generally falls between $2,500 and $5,500.
What drives your specific cost here in Jacksonville is access. A pre-1940s Riverside or Avondale home with retrofitted ductwork in irregular, hard-to-reach runs costs more to clean than a standard Arlington ranch with attic access. We’ll tell you that in advance, in writing. Every estimate includes a camera inspection, the full written scope, and the documented photo record as a standard deliverable. No per-vent pricing, no coupon math, no surprises after the van arrives.

FAQs - Lennox Air Duct Cleaning in Jacksonville
Your filter catches particulate, not the microbial biofilm growing on the inside of your flex duct liners and evaporator coil. In Jacksonville’s river-basin humidity, condensation inside aging Lennox ducts rarely dries out, so mold and bacteria colonize the duct surface itself and the smell recirculates every time your Merit or Elite air handler cycles on. The fix is a full duct and coil cleaning with sanitizing, documented photo record included. Call (806) 606-6902 for a written inspection scope.
Usually, yes. In Jacksonville’s slab-on-grade homes, attic-mounted Lennox air handlers deal with two forces at once: the coil collects microbial buildup because the humidity never lets it dry, and the flex duct runs have likely sagged, kinked, or disconnected due to attic heat exceeding 130°F. Both conditions reduce airflow and spread odor. A camera inspection through every run tells us which problem is yours, and the written scope tells you what it costs before we start.
We use genuine Lennox OEM components when the repair needs factory-spec fit, which is most relevant for coil connections and air handler mating surfaces. For flex duct replacement, sealing, and insulation work, we use high-grade aftermarket materials that hold up better in Jacksonville’s attic heat than the original factory flex. Either way, the parts decision is written in your scope and photographed before installation.
Jacksonville’s river basin keeps ground-level humidity elevated even on days when coastal breezes provide relief. That moisture infiltrates aging flex duct seams and condenses inside the ductwork, creating conditions for mold colonization faster than inland Florida cities experience. Most Jacksonville Lennox homes need duct and coil cleaning every 3 to 5 years, sooner if you’re noticing persistent odors or debris at the registers. Call (806) 606-6902 and we’ll put a camera in your ducts to show you where you stand.
Yes. We use coil-cleaning methods appropriate for the specific Lennox coil design, and we document every step. Our process doesn’t void a Lennox manufacturer warranty because we’re cleaning and sanitizing using trade-recognized equipment and procedures, not modifying the coil or the system’s function. The documented photo record you receive includes coil before-and-after images, so you have proof of what was done.
