Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Air Duct Cleaning Across Jacksonville
Air duct cleaning in Jacksonville typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. We dispatch from our Jacksonville office and serve homes from Orange Park to Atlantic Beach, with scheduling coordinated locally so you’re not waiting on a crew driving down from another market.
We’ve been cleaning ducts in this city long enough to know what Jacksonville’s climate does to a system. The humidity doesn’t quit, the oak pollen comes in waves, and the older neighborhoods hide ductwork that hasn’t been opened since the Truman administration. Our Air Duct Cleaning team uses Rotobrush rotary systems and Nikro negative-air machines to pull out what’s actually in there, not just what’s easy to reach. If you’re in Riverside, Avondale, Arlington, or out on the Southside, we’ll give you a written price before we touch anything. Call (361) 326-5060.
Why Hollis Air Duct Cleaning Is Jacksonville’s Preferred Air Duct Cleaning Company
We’re part of the Garrison Partners family, and we’ve operated under The Garrison Standard since 2004. That means background-checked, uniformed technicians who arrive inside the quoted window, price the job in writing before any work starts, and leave the site clean. No callback queues, no voicemail loops. Phones are answered by a live person 24 hours a day, 7 days a week.
Jacksonville homeowners call us because they’ve dealt with the alternative: a teaser coupon that balloons once the van is in the driveway, or a crew that vacuums the registers and calls it done while leaving crushed flex runs and moldy air handlers untouched. We don’t work that way. The price we write down is the price you pay. And every job carries our 365-Day Done Right Promise: if the work fails within a year, we come back and make it right at no charge, including a free second visit.
Our crews know the local housing stock. They’ve worked in 1920s bungalows with original galvanized metal trunks wrapped in cloth-backed tape, 1950s ranches in Arlington with sagging flex duct in the crawlspace, and newer Southside builds where mold takes hold in a single season when the drain pan overflows. That local knowledge changes what we find and how we fix it.
Air Duct Inspection in Jacksonville
Air Duct Inspection in Jacksonville starts with a camera run through your supply and return trunks, followed by a written report that shows you exactly what we’re seeing. Most Jacksonville homeowners schedule an inspection when they notice uneven airflow, a musty smell that won’t clear, or after any water intrusion event. A full video inspection here runs $150 – $250, and if you move forward with cleaning, we apply that toward the job.
What We Look For in Older Systems
In Jacksonville’s historic districts, we’re checking for disconnected branch runs behind plaster walls, crushed flex duct from decades of attic traffic, and original metal trunks with joints sealed by deteriorating cloth tape. The inspection also covers your air handler cabinet and blower motor, where constant summer runtime packs the coil with biological growth that recontaminates cleaned ducts.
Post-Flood and Storm Inspections
After Jacksonville’s frequent summer thunderstorms or any hurricane-season flooding, we inspect for hidden mold in low-lying return plenums and water-stained flex runs. San Marco and Riverside homes are particularly vulnerable. Even if you don’t see surface mold, water in the duct system creates conditions that need documenting before they spread.
Residential Air Duct Cleaning in Jacksonville
Residential Air Duct Cleaning in Jacksonville means source removal: agitating and extracting built-up debris from your entire duct network, not just vacuuming what’s visible at the registers. A typical single-system home here runs $350 – $550, with larger homes or systems with significant mold remediation needs reaching $650. We use HEPA-filtered negative-air containment so what we loosen doesn’t settle back into your living space.
The Real Fix in Historic Homes
In Riverside and Avondale, the real problem is rarely just dirty ducts. Original galvanized metal trunks leak at every joint, and old cloth-backed tape has turned to dust. We mastic-seal those leaks and re-insulate exposed runs, which is what actually stops the musty smell and uneven temperatures. Vacuuming alone would leave the root cause untouched.
Flexible Ductwork in Humid Conditions
Southside homes with flex duct are prone to mold growth when condensation builds inside sagging runs. Our rotary brush system from Rotobrush cleans the interior surface, and we check for proper slope and support. If your drain pan has been overflowing, we’ll flag it, because cleaned ducts get recontaminated fast when the air handler is still breeding mold.
Trusted Brands We Service in Jacksonville
We carry Aprilaire and Honeywell filtration products, use Abatement Technologies HEPA containment gear, and stock Guardsman antimicrobial treatments for mold-prone systems. Our Nikro negative-air machines and Rotobrush rotary systems are the same tools commercial crews use in Jacksonville’s hospitals and schools. We don’t show up with shop vacs and a brush kit from the hardware store. For Jacksonville homeowners, that means parts and materials are on the truck, not on order, and most jobs finish in one visit without a return trip.
Common Air Duct Cleaning Problems We See in Jacksonville Homes
- Crushed or disconnected flex runs in attics. Jacksonville’s older ranches and mid-century homes in Arlington often have flex duct that has been stepped on during roofing work or sagging from failed supports. We find these with camera inspection, then reconnect or replace the run properly.
- Mold in return plenums after water intrusion. The combination of 50-plus inches of annual rain and flat, flood-prone terrain in neighborhoods like San Marco means water finds its way into low-lying duct sections. We treat with antimicrobial and seal to prevent recurrence.
- Original metal trunks leaking at every joint. Historic homes in Riverside and Avondale have galvanized steel ductwork with joints wrapped in cloth-backed tape that has deteriorated over 80-plus years. Mastic sealing is the fix, not more tape.
- Biological growth in air handler cabinets. Jacksonville’s May-to-October AC runtime packs the blower motor and evaporator coil with mold and pollen. Skipping this component during a duct cleaning means recontamination within weeks. We clean and treat it as standard.

FAQs About Air Duct Cleaning in Jacksonville
Jacksonville’s humid subtropical climate and massive oak pollen loads mean mold and pollen accumulate in ductwork far faster than in drier, less forested cities. Year-round AC use from May through October pulls that pollen deep into return ducts, while humidity above 60 percent supports mold growth in flex duct and air handler cabinets. Most Jacksonville homes benefit from cleaning every 3 – 5 years, or sooner after any water intrusion event. Call (361) 326-5060 to schedule an inspection.
Yes. Mold in duct systems often starts in hidden areas: the return plenum, low-lying flex runs, or behind the air handler where standing water collects. By the time you see it on vents, it has spread. We recommend a camera inspection after any flooding to document conditions before they worsen. The inspection cost applies toward cleaning if needed. Call (361) 326-5060.
We regularly find galvanized steel trunks with joints wrapped in deteriorating cloth-backed tape, leaks that have gone unsealed for decades, and debris from old renovations including plaster dust and remnants of knob-and-tube wiring insulation. In a 1920s bungalow off Park Street in Riverside, our tech pulled a camera inspection through the return and found a crushed 6-inch branch run behind a plaster wall, packed with renovation debris and old knob-and-tube insulation fragments. We set up negative pressure with a HEPA-filtered Nikro unit, used agitation tools to loosen the caked dust, then mastic-sealed the leaks in the original metal trunk and reconnected the crushed run with a proper takeoff. The homeowner said the musty smell that had lingered for years finally cleared.
We use source-removal methods consistent with NADCA guidelines, including HEPA-filtered negative-air containment on every job. That means a Nikro machine creates suction at the air handler while we agitate debris with rotary brushes, capturing what we loosen instead of letting it settle back into your living space. We also photograph before-and-after conditions so you see what was removed. Call (361) 326-5060 for specifics on your system.
Signs include a persistent musty smell when the AC runs, visible dark staining on vent registers, or uneven cooling that suggests restricted airflow from a partially collapsed or blocked run. Because flex duct has a ribbed interior that traps moisture, mold can establish within a single season in Jacksonville’s humidity if the drain pan overflows or the duct is poorly supported. A camera inspection confirms what you’re dealing with. Call (361) 326-5060 to book one.
