Which Ductwork Service Do You Need?
Most ductwork calls start with a symptom, not a service name. Pick the one that sounds most like yours.
Ductwork Services in Jacksonville, FL
Six specific services cover everything from a quick clean to a full replumb. Most homes only need one or two — an inspection tells us which.
Duct Cleaning
Certified Rotobrush whip-and-vacuum cleaning that pulls out years of dust, dander, pollen, and mold spores. Most jobs done in a half day.

Duct Sealing
Mastic sealing at every joint and pinhole leak. Stops the 20–30% of conditioned air your ducts are leaking — and the energy bill creep with it.
Learn more
Duct Inspection
Free video duct inspection — we run a camera through your supply and return runs to show you exactly what’s up there. No upsell pressure.
Learn more
Duct Replacement
Full replacement when ducts are crushed, disconnected, asbestos-wrapped, or mold-laden in the insulation. New flex or sheet-metal, sized to your system.

Correcting Airflow
Fix hot/cold rooms without replacing the whole system — adding returns, balancing dampers, sometimes a small zoning solution.

Airflow Testing
Manometer + flow-hood testing measures static pressure and CFM at every register. The diagnostic that tells us exactly which fix you need.
Learn moreClean & Seal, or Replace? Here's How We Decide
Most Jacksonville ducts don’t need to be replaced. But some absolutely do. Here’s the framing we walk through after a free inspection.
Clean & Seal
Clean & Seal What You Have
If the ducts are physically intact, cleaning and sealing usually solves the problem at a fraction of replacement cost.
- Ducts are intact — no crushed or disconnected runs
- Insulation is dry, no mold deep in the materials
- Built since the mid-1980s (no asbestos wrap)
- Static-pressure test shows leaks under 25%
- Mostly cosmetic dust + minor airflow imbalance
Replace
Replace and Reset
When the bones are wrong, no amount of cleaning fixes it. New ducts pay off in lower bills, even airflow, and cleaner air.
- Crushed, disconnected, or sagging duct runs
- Asbestos-wrapped ducts (pre-1980)
- Mold deep in the duct insulation or boards
- Static-pressure test shows leaks over 30%
- Replacing the AC system anyway — right-size both
The Ductwork Team Built on Speed, Skill & Honesty
Most contractors will quote you a duct cleaning over the phone. We won’t — because we’d rather not sell you one you don’t need.
Free Video Inspection
A camera through your ducts tells the truth. We show you the footage — clean, cracked, or in between — and quote only what’s needed.
Rotobrush + NATE Certified
Whip-and-vacuum cleaning that actually removes debris, not just stirs it up. NATE-certified techs trained on every duct type sold in Jacksonville.
Flat-Rate, No Surprises
Same upfront price quoted before any work begins. No “we found mold” mid-job pricing games, no add-ons that weren’t in the quote.
Lifetime Workmanship
If we cleaned it, sealed it, or replaced it — we stand behind it. Workmanship guarantee for life on every install.
Frequently Asked Questions About Ductwork
-
How often should HVAC ducts be cleaned?
Most Jacksonville homes benefit from a Rotobrush cleaning every 3–5 years. Sooner if you have pets, allergies, recent construction or renovation work, visible mold, or are buying a home where the duct history is unknown. Maintenance-plan members get a free annual duct-and-airflow check that flags when cleaning is actually needed — not just sold.
-
What is duct sealing and is it worth it?
Duct sealing closes the gaps and pinhole leaks at every duct joint with mastic (a paint-on rubberized sealant). Typical Jacksonville homes lose 20–30% of conditioned air to duct leaks — sealing usually pays for itself within 2–3 years in lower energy bills, and immediately makes rooms feel more even.
-
How do I know if I need new ductwork vs cleaning or sealing?
Cleaning + sealing fixes most issues if the ducts are physically intact. Replacement is the right call when ducts are crushed, disconnected, asbestos-wrapped, or have mold deep in the insulation — none of which a cleaning will solve. A free video duct inspection tells us which it is.
-
Does duct cleaning improve indoor air quality?
Yes — when it’s actually needed. Removing accumulated dust, pet dander, pollen, mold spores, and construction debris from inside the ducts reduces what gets recirculated through the home. Pair it with a high-MERV filter or whole-home air purifier for the biggest impact on allergies and asthma.
-
Why are some rooms hot or cold no matter the thermostat setting?
Usually airflow imbalance — undersized return ducts, crushed or kinked supply runs, missing dampers, or a single-zone system trying to cover too much square footage. Airflow testing measures it directly, and airflow correction (adding returns, balancing dampers, sometimes a small zoning system) fixes it without replacing the whole system.
-
How long do ducts last in Florida?
Modern flex duct and sheet metal last 15–25 years in Jacksonville’s climate if installed correctly. Crawl-space and attic ducts in Florida humidity tend to degrade faster than ducts in conditioned space. Anything pre-1980s, asbestos-wrapped, or visibly sagging needs to be on your replacement radar.
