Air Duct Cleaning Cost in Jacksonville, FL: What You’ll Actually Pay in 2024
Most homeowners in Jacksonville pay between $350 and $650 for professional air duct cleaning on a typical 1,500–2,500 square foot home, with larger homes or systems with multiple HVAC units running toward the higher end.

That range isn’t arbitrary. It’s shaped by something most pricing guides miss: Jacksonville’s brutal attic environment. The combination of our relentless coastal humidity and 140–150°F attic temperatures in summer turns ductwork into a pressure cooker that degrades faster here than nearly anywhere else in Florida. We’ve pulled collapsed fiberglass liner out of trunk lines in Arlington homes built right after the 1968 consolidation, and we’ve seen supply plenums in Westside ranches growing mold so thick it looked like felt. That local reality means cleaning a Jacksonville system often takes longer, requires more aggressive agitation, and sometimes uncovers damage that changes the scope on the spot.
Why Jacksonville’s Climate Drives Duct Cleaning Costs Higher Than Inland Florida
The St. Johns River corridor and our Atlantic proximity keep dew points stubbornly high even in January. Your AC runs 10–11 months a year, and those cold supply ducts sit in superheated attic air that never lets them fully dry between cycles. Condensation pools in duct boots. Fiberglass liner delaminates. The particulate load inside a 1980s tract home system here isn’t just dust — it’s degraded liner fragments, mold spores, and the byproducts of decades of moisture cycling.
Steven Ramirez, our Owner & Lead Technician, grew up on Jacksonville’s Southside and has spent eight years crawling through these exact conditions. He got into this trade after his own kid struggled with allergies and he wanted to understand what was actually moving through the air in their house. That question still drives how we quote jobs: we inspect before we price, because what looks like a standard cleaning can turn into a repair-and-seal situation once you get eyes inside a 40-year-old flex duct run.
Generalist HVAC companies — the ones that treat duct cleaning as a winter filler between installs — often miss this. They show up with a shop vac and a brush, run it for two hours, and leave. We’re using Rotobrush and Nikro systems built for restoration contractors, not consumer-grade equipment, because Jacksonville’s duct conditions demand it.
Air Duct Cleaning Price Breakdown for Jacksonville Homes
| Service Component | Typical Range |
|---|---|
| Standard residential duct cleaning (single HVAC system, up to 15 vents) | $350 – $550 |
| Large home or multi-zone system (16–25 vents) | $550 – $750 |
| Homes with severe contamination (visible mold, heavy debris, collapsed liner) | $650 – $950 |
| Duct repair and sealing (per linear foot of accessible ductwork) | $8 – $18 |
| Air quality sanitizing with EPA-registered treatment | $150 – $300 |
| Dryer vent cleaning (add-on or standalone) | $120 – $200 |
These ranges reflect what we’re actually quoting in Jacksonville neighborhoods from Mandarin to Arlington to the Northside. The 1970s–1990s slab-on-grade stock that dominates our market puts virtually all ductwork in unconditioned attics, so we’re not dealing with crawl-space accessibility — we’re dealing with 130°F August afternoons and brittle fiberglass that crumbles on contact.
What Can Push Your Price Toward the High End
Several factors specific to Jacksonville homes regularly move quotes above the base range:
- Aging fiberglass-lined metal ductwork — Common in post-consolidation tract homes across the Westside and Arlington, this liner degrades into airborne fibers that require extended agitation and HEPA containment.
- Visible mold or mildew in plenums — The humidity cycle here means we find active growth in roughly 30% of systems over 25 years old; remediation-grade sanitizing adds time and material cost.
- Disconnected or collapsed flex runs — Attic heat brittles flexible duct; we’ve found fully separated runs dumping conditioned air into insulation in homes off Mandarin Road and throughout the Intracoastal West area.
- Multiple HVAC systems — Larger homes in gated communities or newer construction often have separate upstairs/downstairs units, each requiring independent cleaning.
- Accessibility issues — Tight attic hatches, blown-in insulation depth, or ductwork buried under decking all add labor time.
We don’t bait-and-switch on these. Steven inspects accessible components before finalizing any quote, and we’ll show you what we’re seeing — including photos from inside your system — so the price matches the actual condition.
What You’re Paying For: Our Process and Equipment
Every job we perform uses professional-grade equipment from Rotobrush and Nikro — the same systems restoration contractors deploy after fire and water damage. These aren’t shop vacs with longer hoses. The Rotobrush system uses a spinning brush head with simultaneous vacuum extraction to dislodge and capture debris in one pass, while our Nikro negative air machines maintain containment pressure so nothing escapes into your living space.
For homes with air quality concerns — allergy sufferers, recent renovations, or post-mold remediation — we also work with Honeywell and Aprilaire whole-home systems. That ecosystem approach matters because clean ducts connected to a dirty coil or ineffective filtration just recirculates the same problem. If it moves air through your house, it’s worth doing right the first time.
Our home page outlines our full service range, but on cost-focused calls we emphasize this: the owner shows up. Steven Ramirez personally performs or directly oversees every job. You’re not getting a rotating subcontractor crew that changes month to month. That consistency shows up in our nearly 900 verified reviews — 890 of them, averaging 4.9 stars across eight years of duct-only focus.

FAQs
Most Jacksonville homeowners pay between $350 and $650 for professional air duct cleaning on a typical single-system home, with larger or more contaminated systems ranging up to $950. Call (888) 265-8912 for a free estimate tailored to your home’s size and duct condition.
Repair and sealing typically costs $8–$18 per linear foot and makes sense for isolated damage in otherwise sound systems; full replacement runs $2,000–$5,000+ and is usually only justified when multiple runs are collapsed, mold-permeated, or made of obsolete materials. We assess this during inspection and won’t recommend replacement unless repair is genuinely impractical.
Yes, but it requires remediation-grade cleaning followed by EPA-registered sanitizing — not just standard debris removal. We use containment protocols and specialized treatments for active mold, and we’ll tell you honestly if the contamination is too extensive for cleaning alone. Call (888) 265-8912 if you suspect mold; we’ll inspect before quoting.
Every 3–5 years for typical households, but sooner if you have allergy sufferers, pets, recent renovations, or a home built in the 1970s–1990s with original fiberglass-lined ductwork. Jacksonville’s humidity and attic heat accelerate degradation, so older systems here often benefit from more frequent inspection.
