AfterLennox Air Duct Cleaning in Jacksonville, CA | Hollis Air Duct Cleaning
We provide Air Duct Cleaning - Jacksonville for Lennox systems across the city, and the work here is different because of what this city throws at your ductwork: oak pollen in spring, mold-friendly humidity all year, and flood debris in older neighborhoods like San Marco and Riverside. Hollis Air Duct Cleaning is an independent Jacksonville company. We’re not affiliated with or authorized by Lennox, but we know their equipment inside and out, from old Merit-series air handlers to current Dave Lennox Signature Collection systems. Call (361) 326-5060 for a written, flat-rate quote before any work starts.
Why Jacksonville Residents Choose Us for Lennox Service
Lennox builds solid equipment, but in Jacksonville the ductwork attached to that equipment works harder than most people realize. Our Jacksonville Dryer Vent Cleaning team sees the same climate stress on connected ventilation systems. Our technicians have cleaned and sealed Lennox systems in Riverside bungalows, Arlington ranches, and Southside new construction, so we know how each housing type affects the ducts. Roy Castellanos, our owner, came up through the mechanical trades in Los Angeles County and completed the sheet metal and air conditioning program at Los Angeles Trade-Technical College. That means when we open a Lennox air handler, we’re not guessing at what we’re looking at. We understand coil faces, return plenums, and blower loads, and we explain what we find in plain terms before we touch anything.
We’re part of the Garrison Partners family and we operate under The Garrison Standard. That means a written price before work begins, a background-checked and uniformed technician at your door, and a 365-Day Done Right Promise in writing on every job. If something fails within a year, we come back and make it right at no charge. For Lennox owners in Jacksonville, knowing the crew understands your specific equipment matters just as much as the guarantee behind the work.

Common Lennox Air Duct Cleaning Problems We Solve in Jacksonville
These are the issues we see most often on Lennox systems in this city, and each one connects to a specific Jacksonville condition:
- Pollen-packed evaporator coils in cased upflow air handlers. Lennox evaporator coils in the cased upflow air handlers common in Jacksonville closets collect oak pollen and pine debris fast. From May through October, the AC runs nearly constantly, pulling that pollen through return ducts and onto the coil face. The blower then strains against a matted coil, which drives up amp draw and shortens blower motor life.
- Mold inside foil-faced flex duct on newer Southside construction. The foil-faced flexible duct runs often used on Lennox systems in newer Southside homes absorb moisture in Jacksonville’s year-round humidity. Where runs sag or get compressed in tight attic spaces, condensation forms and mold grows on the interior liner. We can often clean and re-support the flex rather than replace it, which saves you real money.
- Seam leaks and disconnected boots in older metal trunk lines. Lennox metal trunk lines in historic Riverside and Avondale bungalows have settled for decades. Seams open, boots pull loose, and the system starts pulling musty crawlspace air instead of air from the living space. In flood-zone homes, that crawlspace air carries exactly the odors you don’t want circulating through the house.
- Silt and plaster dust in horizontal coil cabinets after floods. In San Marco and Riverside homes that flooded during events like Hurricane Irma, Lennox air handlers with horizontal coil cabinets trap silt and renovation debris. Plaster dust from old remodels settles inside the cabinet, and cabinet insulation can stay damp long after the drywall looks fine.
- High static pressure from dirty return ducts forcing premature blower failure. We see this across Jacksonville. Restricted return ducts force Lennox blowers to run harder, which burns out capacitors and blower motors earlier than they should. Cleaning the return side of a Lennox system is one of the most cost-effective things a homeowner can do to extend equipment life.
Lennox Service in Jacksonville: What Local Conditions Mean for Your Equipment
Here’s something a generic Lennox page or a generic Jacksonville duct cleaning page won’t tell you: the flood history of San Marco and Riverside shapes what sits inside original metal duct runs in those neighborhoods. Homes built before 1950 with their original ductwork have never had those ducts removed, and after each flood event, water and renovation debris work their way inside. We regularly find plaster dust from multiple remodels and degraded knob-and-tube wiring insulation sitting at the bottom of return trunks in these homes. The ducts were never replaced, so neither was the debris. For Lennox owners, that means your air handler is pulling air through decades of accumulated material before it ever reaches the coil. That’s not a generic duct cleaning problem. That’s a Jacksonville-specific problem tied to this city’s housing stock and flood history. The solution is a thorough return duct cleaning, coil cleaning, and sealing of the trunk seams so the system stops inhaling from the crawlspace. In a 1940s bungalow in Avondale, we opened a Lennox Merit air handler after the homeowner complained of a musty smell every time the AC kicked on. The return trunk was packed with oak pollen, plaster dust from a kitchen remodel, and chunks of degraded knob-and-tube insulation. The coil was matted enough that the blower was pulling high amps. We cleaned the coil and blower, sealed the return seams with mastic, and the smell and static pressure both cleared up. That’s the kind of job we handle regularly across Jacksonville service area.
Lennox Models & Products We Service in Jacksonville
We work on the full range of Lennox residential equipment found in Jacksonville homes. That includes the older Merit Series split systems and air handlers, Elite Series units, and the current Dave Lennox Signature Collection line. We also still see CompleteHeat systems and Pulse furnace-era ductwork in original ranches across the city, and those older metal ducts need a different approach than modern flex. When parts are needed, we use OEM-spec Lennox-compatible filters, gaskets, and flex duct components where fit matters, and quality aftermarket mastic, insulation, and sealing materials everywhere else. You don’t need to pay dealer markup on generic hardware. On most Lennox equipment, honest duct sealing, coil cleaning, and flex repair beats replacing the air handler outright, unless the cabinet is rusted through or the coil is leaking refrigerant.
Lennox Service Pricing in Jacksonville
We give one flat price per system in writing before any work starts, and that price does not move at the door. For a typical Lennox system in a Jacksonville home, full air duct cleaning on a single system generally runs between $400 and $800 depending on the number of returns, the length of the runs, and how accessible the ductwork is. Cleaning a badly fouled Lennox evaporator coil adds $150 to $300 in most cases. Flex duct repair or replacement runs $200 to $500 per run, depending on length and access. A full Lennox system with coil cleaning, return duct cleaning, and flex repair often lands between $600 and $1,200. What drives cost in Jacksonville specifically is mold remediation on flex liner, crawlspace access in older Riverside and Avondale homes, and heavily loaded return trunks from pollen and renovation debris. Your written estimate covers all of it, line by line. Call (361) 326-5060 for an exact quote, and Roy will walk you through what the system actually needs.

FAQs – Lennox Air Duct Cleaning in Jacksonville
Yes, we clean and seal Lennox ductwork and coils throughout Jacksonville, but we are an independent company and we are not affiliated with, authorized by, or endorsed by Lennox. That independence means we’re free to recommend the most honest fix for your system, not the one that moves the most parts. Our techs have worked on Merit, Elite, and Dave Lennox Signature Collection equipment across the city for years, and we know how their coils and cabinets behave in this climate. If we can clean and seal your existing ductwork rather than replace it, we’ll tell you that straight.
Mold grows fast on Lennox air handlers in Jacksonville because the city’s humidity stays high year-round, the AC runs constantly from May through October, and in newer homes the flex duct runs often sag and collect condensation. Add the region’s heavy oak pollen load in spring, and you get a damp, dusty environment inside the duct system that feeds mold. The fix is cleaning the coil and blower, cleaning or replacing moldy flex liner, and re-supporting any sagging runs so condensation stops pooling. Call (361) 326-5060 and we’ll inspect your system and give you a written quote.
Most of the time in San Marco and Riverside, the ductwork needs cleaning and sealing, not full replacement. After flood events like Hurricane Irma, silt, plaster dust, and insulation debris settle into original metal duct runs that were never removed. The cabinet insulation in horizontal coil Lennox air handlers can also stay damp long after the drywall looks fine. We remove the debris, clean the coil and blower, and seal the return seams with mastic. Replacement is only necessary if the metal itself has rusted through or the flex liner is beyond cleaning. Call (361) 326-5060 and we’ll give you an honest assessment with a written price.
Yes, and it gets in faster here than almost anywhere else in the country. Jacksonville’s oak and pine pollen load in spring is significant, and because the AC runs so much of the year, return ducts pull that pollen in continuously. What we find inside Lennox return trunks in this city is often a thick pollen mat on the coil face and a layer of fine yellow dust along the return duct interior. On systems where the return is undersized for the blower, the problem compounds because the air moves faster and pulls more debris. Cleaning the return side and the coil once a year in pollen-heavy neighborhoods makes a measurable difference in blower strain and indoor air quality.
In most cases yes. A sagging or compressed flex run on a Lennox system in Jacksonville usually needs re-supporting, and if the interior liner has mold, we can clean it or replace just that section of flex rather than the entire run. We charge per run for flex repair or replacement, and the written quote tells you exactly which sections need work and what each one costs. If the existing flex is simply too far gone, we’ll tell you that plainly and show you why. Call (361) 326-5060 for a free estimate and we’ll walk the system with you.
