HVAC Duct Installation
HVAC Duct Installation is the process of fitting new ductwork into a home that either never had it, has an addition that needs conditioning, or has ductwork so deteriorated that patching no longer makes sense. In Jacksonville, we see this most often in older homes in Riverside and Avondale where the original metal ducts have rusted through from decades of humidity, or in new additions off the back of homes in Mandarin and Air Duct Repair in Orange Park. Linden Air Duct Jacksonville installs rigid and flexible duct systems sized to your specific air handler, using professional-grade equipment from Rotobrush and Nikro. A full HVAC duct installation in Jacksonville generally runs $2,500 to $6,000 depending on the number of runs, accessibility, and whether we’re working in an attic, crawlspace, or between floors.
New Construction and Additions
When a Jacksonville homeowner adds a mother-in-law suite or finishes a garage, the existing system rarely has the capacity or reach to condition the new space properly. We calculate the cubic feet per minute your air handler delivers and size the new branch ducts accordingly, so the addition doesn’t steal airflow from the rest of the house. We also seal every joint with mastic, not tape, because Jacksonville’s heat and humidity break tape down within a few years.
Whole-Home Retrofit
Older Jacksonville homes built before central air often have a patchwork of duct runs from different eras, different materials, and different installers, and it shows. A whole-home retrofit replaces that patchwork with a single, properly sized system. We start with a Manual J load calculation so the new ducts match the actual heating and cooling demands of your house, not a guess from the square footage.

Air Duct Replacement
Fleming Island Air Duct Repair means removing your existing ductwork and installing new ducts in its place, and it’s the right call when repairs would cost more than replacement or the existing ducts are too compromised to hold air. In Jacksonville, duct replacement is common in homes where the original flex duct has been chewed by rodents, crushed by attic storage, or degraded to the point that it’s leaking 30 percent or more of the air you’re paying to condition. Linden Air Duct Jacksonville handles full and partial replacement, always with a written price before work begins. Expect air duct replacement in Jacksonville to run $1,800 to $4,500 for most single-family homes, with partial replacement of a few runs starting lower.
Partial Replacement: One Section at a Time
Sometimes only one trunk line or a few branch runs have failed, usually the ones nearest the air handler in the attic or the ones running through a damp crawlspace. We’ll replace just the damaged sections and tie them into the existing system with properly sealed connections. You don’t pay to replace ducts that are still doing their job.
Full Replacement: When Patching Isn’t Enough
When more than half the system is compromised, full replacement usually costs less per year of service than continuing to patch leaks. We’ll remove the old material, inspect the plenum and air handler connections, and install new, properly insulated ductwork sized for your home’s actual airflow needs. Every full replacement in Jacksonville comes with our written guarantee and the 365-Day Done Right Promise.
Ductwork Repair
Ductwork Repair is the targeted fix: sealing leaks, reconnecting separated joints, patching holes, and replacing damaged sections so the air you pay to heat and cool actually reaches your rooms instead of your attic. In Jacksonville, we regularly find disconnected flex ducts in homes where a previous contractor or a curious homeowner crawled through the attic and knocked a run loose. Linden Air Duct Jacksonville repairs all common ductwork failures, and the job typically costs $250 to $800 when the damage is isolated. Larger repairs, like resealing an entire system, fall between $800 and $1,500.
Leak Sealing and Air Loss
Most Jacksonville homes lose 20 to 30 percent of their conditioned air through duct leaks, which means the air handler works harder and the bill goes up while comfort goes down. We seal joints with mastic and reinforce with foil tape where needed, then use a manometer to measure static pressure before and after so you can see the difference. The goal is a tight system, and we show you the numbers.
Disconnected and Crushed Runs
Flex ducts get crushed by boxes in the attic, kinked around framing, or simply pull apart at the boot connection over time. A disconnected run means one room gets no air at all, which is a repair that usually takes under an hour once we locate it. We reattach, reseal, and support the run so it stays put.
Duct Replacement
Duct Replacement is the removal and reinstallation of ductwork when the existing material has failed, and it differs from repair in scope: replacement means out with the old, in with the new, not patching what’s there. Jacksonville’s humidity accelerates the breakdown of flex duct, especially in vented attics where temperatures hit 140 degrees in August, and older metal ducts rust through in crawlspaces within a few decades. Linden Air Duct Jacksonville provides straight answers on when replacement beats repair, and the price for duct replacement in Jacksonville typically runs $1,800 to $4,500, always written down before we start.
When Replacement Beats Repair
If the duct liner is torn, the insulation is soaked from a roof leak, or the duct has been home to rodents, replacement is the honest recommendation. Insulation that’s been wet loses its R-value permanently, and rodent damage inside flex duct cannot be sanitized away. We’ll show you photos of the damage so you can see why replacement is the right call.
Material Choice for Florida Attics
In Jacksonville, we recommend insulated flex duct with a minimum R-8 rating for attic installations, which is current Florida building code for supply ducts. Rigid metal duct is better where space allows and access is open, because it resists crushing and moves air with less resistance. We’ll recommend the material that fits your attic layout and your budget, and explain the trade-offs in plain English before you spend a dollar.
Ductwork Installation
Ductwork Installation is the complete job of designing, sizing, and installing a duct system, whether for a new build, a major renovation, or a home that never had proper ducting. In Jacksonville, we’ve installed systems in everything from 1920s bungalows in Springfield to new construction in Nocatee, and the process always starts with a load calculation, not a guess. Linden Air Duct Jacksonville handles the full installation from air handler connection to register placement, and complete ductwork installation in Jacksonville generally costs $2,500 to $6,000 depending on home size and attic accessibility.
Designing the System Properly
A duct system is only as good as its design, and undersized ducts are the reason so many Jacksonville rooms never cool down in July. We calculate airflow requirements room by room, size each run accordingly, and design the layout so every register delivers the air it should. Then we install it with sealed joints and proper support, not just wire hangers and hope.
Replacing DIY or Subpar Work
We’ve walked into more than a few Jacksonville attics where a previous owner’s handyman job left ducts strung across rafters with no support, no sealing, and no insulation. Those systems leak and sag until they fail. We remove the mess and reinstall it correctly, with mastic-sealed connections, proper hangers, and insulation that meets Florida code.
Brands We Service
We work on duct systems connected to every major air handler brand, and our technicians are experienced with the specific airflow characteristics of Nikro and Rotobrush equipment, which we also use on the cleaning side. If your ducts were installed with Nikro fittings or you have a Rotobrush system in your attic, we know how they’re put together and how to repair them without causing additional damage. Our familiarity with these brands means faster diagnosis and fewer surprises during the repair.
On the air quality side, we’re experienced with whole-home systems from Honeywell and Aprilaire, including media cabinets and dehumidifiers that tie directly into your ductwork. When we repair ducts in a home with an Aprilaire filter system or Honeywell zoning, we make sure the repairs don’t compromise those components. Whether you have Honeywell, Aprilaire, Nikro, or any other make, we can help.

AfterSigns You Need a Pro Right Now
- One room never reaches temperature. If your bedroom is always 8 degrees warmer than the hallway and the vents are open, the duct feeding that room is likely disconnected or crushed. In Jacksonville summers, that symptom gets worse fast, and the air handler works harder trying to compensate.
- Your utility bill spiked without a change in usage. Duct leaks mean you’re conditioning your attic, not your living room. A 25 percent duct leak can add $40 to $80 a month to a Jacksonville summer electric bill. If the bill jumped and the weather didn’t, the ducts are a prime suspect.
- Dust appears on surfaces within days of cleaning. Leaks on the return side pull attic insulation, dust, and whatever else is up there into your air stream and then into your house. If you dust on Sunday and it’s back by Thursday, your return ducts are pulling from the wrong places.
- You hear whistling, rattling, or flapping from the vents. Whistling usually means air is escaping through a small gap, rattling suggests loose metal, and flapping is often a torn flex liner. All three are repairable now, and all three get more expensive if ignored.
- Musty smell when the system runs. A damp crawlspace or a roof leak can soak duct insulation, and once it’s wet, it molds. The smell travels through the house every time the blower kicks on. Replacing the affected section is the fix, and the sooner the better.
Our Process, Step by Step
- 1
Talk to a real person and book the visit. Call (904) 329-7854 any time and a live person answers, not a voicemail loop. We’ll ask what you’re experiencing, schedule a time that works, and send you confirmation with the name and photo of the technician who’ll arrive.
- 2
On-site inspection and diagnostics. Your technician walks the system from the air handler to the registers, checking for disconnects, crushed runs, leaks, and moisture. We use a manometer to measure static pressure and identify restrictions, and we take photos of everything we find. You’ll see the problem with your own eyes before any repair is recommended.
- 3
Written price before work starts. After the inspection, we write the scope of work and the total price on paper and hand it to you. Nothing is started until you approve it. The price on that paper is the price you pay. No surprises.
- 4
Repair or replacement, done right. We complete the repair using mastic-sealed joints, proper hangers, and materials sized for your system. We work clean, and we protect your floors and furniture. When the work is done, we re-test static pressure and airflow to confirm the fix actually fixed the problem.

How Much Does Air Duct Repair Cost in Jacksonville?
A typical air duct repair in Jacksonville runs $250 to $800 when the damage is isolated, like resealing a few leaking joints or reconnecting one separated run. Resealing an entire system to stop widespread leakage lands between $800 and $1,500. Full duct replacement in a Jacksonville home generally costs $1,800 to $4,500, and complete ductwork installation, including design and sizing, runs $2,500 to $6,000. Those are the honest ranges we quote every day.
What moves the price: accessibility (an open attic costs less to work in than a 24-inch crawlspace), the number of damaged runs, the material you choose, and whether your home has existing moisture damage that needs addressing first. The way to avoid overpaying is simple: get a written price before work starts, and make sure it covers the entire job, not just the first hour. Our free estimate includes the inspection, the diagnosis, and a written quote you can keep. Call (904) 329-7854 and you’ll know exactly what the job costs before you decide anything.
