Trusted Air Duct Repair for Fresno Homeowners
When a duct system leaks, you’re not just losing conditioned air into the attic. You’re paying to heat and cool spaces nobody lives in, pulling dust and insulation fibers into the air your family breathes, and making the HVAC unit work against itself. We see this constantly across Fresno, where summer attic temperatures above 130 degrees punish every small tear or disconnected joint in a duct run. The result is a house that never quite reaches the thermostat setting, dust that returns a day after cleaning, and utility bills that climb every July and August for no apparent reason. As part of the Threshold Group family, serving homeowners since 2004, Linden Air Duct Fresno has repaired, replaced, and reconnected thousands of duct systems across Fresno and the surrounding Valley. Marcus Veale leads our team, and every job we start gets a written price before any work begins. Call (559) 272-4989 for a free estimate and a straight answer about what’s actually wrong.
- Written price before any work starts. You’ll know the full cost of the repair before our technician picks up a tool.
- Written guarantee on every repair. If a covered repair fails, we return and fix it again at no charge.
- Background-checked, identity-verified technicians. You’ll get the name and photo of your technician before they arrive, and they’ll show a photo ID badge at the door.
- A live person answers the phone 24/7. When you call (559) 272-4989, you speak to a real human, not a voicemail loop.
HVAC Duct Installation
HVAC Duct Installation is the process of designing, fabricating, and fitting a complete duct system that moves heated or cooled air from your central unit to every room in the house, and we handle everything from single-room additions to full whole-house installs in Fresno. We also offer Air Duct Repair in Fresno for systems that don’t need full replacement. New installation is the right call when a home addition expands your living space, when the original ductwork was undersized or poorly laid out, or when a remodel changes how rooms connect. In Fresno’s climate, a properly installed duct system has to do two jobs: deliver enough airflow to keep every room comfortable in August, and stay sealed enough that you’re not conditioning the attic. We size the ducts to the room load, not to whatever was easiest at rough-in. A standard HVAC duct installation in the Fresno area typically costs between $1,800 and $4,500, depending on linear footage, the number of drops, and whether we’re working in an attic, crawlspace, or basement.
Installation for Additions
When you add a room or convert a garage into living space, that square footage needs its own supply and return path. Tapping into the existing trunk line without checking capacity is a common mistake; the new room ends up starved for air and the rest of the house runs out of balance. We measure static pressure before and after the work and size the new branch accordingly, so the new room actually holds the temperature you set.
Full System Replacement
Older Fresno homes, especially those built before 1980, often have metal ductwork that’s rusted through, wrapped in degraded asbestos-containing insulation, or so badly designed that three bedrooms share one undersized return. We see the consequence every summer: rooms that differ by 8 to 10 degrees. A full replacement with properly insulated flex duct or new metal, sealed at every joint with mastic, fixes the temperature imbalance and usually drops the energy bill 15 to 30 percent, based on what we measure after the job.
Styles & brands we work with
Air Duct Replacement
Air Duct Replacement is the removal and full swap of damaged, undersized, or failed ductwork sections with correctly sized, properly insulated new duct, and it’s the service you need when a duct has collapsed, torn open, or grown mold inside it. We perform this work regularly in Fresno for homeowners whose flexible duct runs have been shredded by rodents, crushed by foot traffic in the attic, or simply degraded over 20 to 30 years. In a Fresno summer, attic heat causes old flex duct outer jackets to become brittle; the inner liner then separates and collapses, choking airflow. The difference between repair and replacement is straightforward: a repair patches a localized problem, while replacement becomes the smarter choice when the section is too far gone to patch, the insulation is saturated, or mold is present inside the duct. Air duct replacement in Fresno typically runs $425 to $1,100 per run, including materials, labor, mastic sealing at both ends, and debris removal.
Collapsed or Crushed Flex Duct
Flex duct that’s been stepped on, leaned against, or chewed by squirrels loses its round shape and its airflow drops dramatically. A crushed duct is rarely worth trying to reshape; the inner liner has permanent creases that create turbulence and pressure loss at the exact points you need smooth flow. We replace the run, hang it properly with straps no more than 5 feet apart (tighter than most original installs), and seal each connection with mastic, which holds far better than foil tape in 130-degree attics.
Mold or Water Damage
If the duct insulation has absorbed moisture from a roof leak, a busted swamp cooler line, or years of high attic humidity, replacement is usually the only option that gets the problem out of your house. Cleaning a mold-saturated fiberglass liner makes no sense; the spores penetrate the material. We remove the entire affected section, treat the surrounding area, and install new duct with a new, clean liner and fresh R-6 or R-8 insulation.
Ductwork Repair
Ductwork Repair is the targeted fix for leaks, tears, disconnected joints, and failed seals in an existing duct system, and it’s the most common service we perform in Fresno, because Valley attics are brutally hard on ductwork. Homeowners in neighboring communities can also schedule our Air Duct Repair in Clovis with the same team. Every seam, every takeoff collar, every boot connection is a potential leak point, and over time the original tape dries out, the mastic cracks, and the airflow starts bleeding into the attic. We find the leaks with a combination of visual inspection, pressure testing, and sometimes thermal imaging, then seal them properly. The goal of ductwork repair is not just to close the visible gap; it’s to restore the system’s static pressure so that every room gets the airflow it was originally designed to receive. Typical ductwork repair work in Fresno runs $275 to $900 per visit, depending on how many leaks we find and how accessible the problem areas are.
Sealing Leaks and Disconnected Joints
A disconnected branch in the attic is the quiet budget killer. The system keeps running, the thermostat keeps calling for cool air, and up to 30 percent of the conditioned air is escaping before it ever reaches a register. We reattach the run, screw the connection, apply fiberglass mesh, and finish with brush-on mastic, which stays flexible and airtight for years in Fresno attic temperatures. Foil tape alone fails in one Valley summer; mastic is what we use on every joint we touch.
Repairing Boots and Registers
The boot is the metal transition between the duct and the floor or wall register, and it is a frequent source of air loss, especially in older Fresno homes with slab foundations where the boot is embedded in concrete. Over decades, the sheet metal can rust through, the connection to the duct loosens, or the boot separates from the register opening, letting air spill into the wall cavity. We repair or replace the boot, seal it to the register with mastic, and often add a bead of caulk where the boot meets the flooring.
Duct Replacement
Duct Replacement is the service you choose when an entire duct run has failed beyond the point where section-by-section patching makes sense, and we often recommend it in Fresno when multiple repairs are piling up on the same aging system. Some homes reach a tipping point: every summer, a new leak appears; every winter, another connection separates. Paying for a fourth or fifth repair starts to make less sense than swapping the run entirely and starting clean with new, properly sealed duct. It’s not uncommon for us to look at a Fresno home built in the 1980s or 1990s and find the original flex duct has been patched with three different kinds of tape from three different decades. The material is done. Duct replacement in Fresno typically runs $425 to $1,100 per run, the same as replacement, but the work often involves removing and replacing more than one connected run at a time.
Replacing Trunk Lines and Branch Runs
The trunk line is the main artery that runs the length of your attic, and the branch runs connect each register back to it. When the trunk is undersized or deteriorated, individual branch repairs will not solve the fundamental problem, because the system pressure is wrong at the source. We often find original installations where the builder installed an 8-inch trunk feeding six 6-inch branches, which cannot physically deliver the airflow the system needs. Replacing the trunk with a properly sized plenum and reconnecting each branch restores the airflow the HVAC unit is rated for.
Multiple Runs in Older Homes
Fresno neighborhoods like Old Fig Garden, Tower District, and Roosevelt are full of houses with original ductwork from the 1950s and 1960s. We also provide Madera Air Duct Repair for homes with similar vintage systems just north of the city. The metal has rusted, the duct wrap is disintegrating, and the entire system leaks. In those homes, we’ll often replace all the exposed runs at once and cap the work with a system pressure test, so you know the whole system is tight, not just the parts we replaced. The per-run cost is the same, but replacing multiple runs in one visit saves you on trip charges and labor time.
Ductwork Installation
Ductwork Installation is the complete design and build of a duct system where none exists or where the old system is coming out entirely, and it’s work we take on in Fresno for new construction, whole-home remodels, and complete system retrofits. It’s different from HVAC duct installation in one important way: this is the entire airway of the home, not just adding a room or replacing a section. Every room needs the right supply airflow, every supply needs a clear path back to a return, and the system has to work with the specific HVAC unit the home has, not a generic template. We see too many Fresno installations where the builder undersized the ducts by a full inch per run because the duct was cheaper and nobody checked the math. A full ductwork installation in Fresno starts around $2,200 for a smaller home and runs up to $6,000 or more for larger houses, depending on square footage, the number of rooms, and access conditions.
New Construction and Additions
When we install ductwork in a new Fresno home, we design each run off the actual heating and cooling load of the room it’s serving, and we verify that the unit can deliver the rated airflow. That’s the step most rough-in crews skip. We also test the completed system with a pressure gauge before the drywall goes up, which catches leaks that would otherwise be sealed inside the walls and impossible to find later.
Retrofits and Whole-Home Rebuilds
Fresno homes that are being gut-remodeled or converted from window units to central air need a full duct design that matches the new layout, not the old one. We’ll map the room loads, plan the trunk routing through the attic, and choose duct sizes that keep the static pressure within the manufacturer’s spec. With the 365-Day Done Right Promise in writing on every job, if the system is not performing right, Linden returns and makes it right.
Brands We Service
Our technicians work with professional-grade equipment and air-quality products every day. We rely on Nikro for the HEPA filtration and negative-pressure extraction machines that keep dust from leaving the attic and entering your living space during duct repairs. Their equipment is built for the kind of high-volume, sustained use that a Fresno summer schedule demands, and our team has the training and experience to run it properly on every job.
On the air-quality side, we work with Honeywell and Aprilaire products for filtration, humidity control, and whole-home air purification upgrades. When a duct repair reveals an airflow or filtration issue, we can recommend and install the Aprilaire media filter or Honeywell electronic air cleaner that fits your system and your budget. Whether you have a standard split system, a heat pump, or anything else, we can help. If it moves air, we can fix the ducts that carry it.

AfterSigns You Need a Pro Right Now
- One room never heats or cools properly. In a Fresno summer, that hot bedroom is often not an undersized AC; it’s a duct problem. The room’s duct may be crushed, disconnected, or undersized from the original installation, and the system can’t force enough air through it. This gets worse over time, not better.
- Dust accumulates within a day of cleaning. Dust that comes back within 24 to 48 hours is usually being pulled in from the attic through a gap in the return side of the duct system. The duct is sucking attic air, insulation particles, and whatever else is up there directly into the air stream. A duct pressure test will confirm it.
- Utility bills climb with no change in usage. If July’s bill is 40 percent higher than last year and the thermostat settings haven’t changed, you’re paying to condition air that’s leaking out of the ducts. The system is working harder to hit the same temperature, and the extra work shows up on the invoice.
- Whistling or rushing air sounds from the walls or attic. Air escaping under pressure makes noise. A whistle means a leak; a loud rush at a register means the system pressure is too high, usually because a branch run is blocked or crushed. Either one is a repair that only gets more expensive as the leak widens.
- Visible damage in the attic or crawlspace. If you’ve been up there and seen a disconnected duct, a crushed flex run, or a pile of insulation fibers around a joint, that’s the proof you’ve been looking for. The problem is already there; it’s just a matter of whether it gets fixed this month or you keep paying the utility bill for it all year.
Our Process, Step by Step
- 1
We talk through what you’re seeing. When you call (559) 272-4989, a live person answers, not a voicemail. You describe the symptoms: the hot room, the dust, the high bill. We’ll ask a few questions to get a sense of the system and the home.
- 2
A technician arrives at your home. Before the appointment, you receive the technician’s name and photo. When they arrive, they’ll show you a photo ID badge at the door, which is the Threshold Standard on every visit. The technician is background-checked and identity-verified, no exceptions.
- 3
The inspection, including a pressure test. We inspect the full duct system: attic, crawlspace if you have one, every boot and register, and all connections back to the unit. The pressure test measures exactly how much air is leaking and where. We’ll show you the results and point out the problem areas, so you can see the damage for yourself.

We complete the work and you get a written guarantee. Every repair is backed by the 365-Day Done Right Promise in writing. If a covered repair fails within the year, we return at no charge and make it right. You’ll have the guarantee in writing in your hand before our technician leaves your home.
How Much Does Air Duct Repair Cost in Fresno?
A typical air duct repair job in Fresno runs between $275 and $900, with most repairs landing in the $350 to $550 range. The exact price depends on how many leaks we find, whether the problem is in an accessible attic or a tight crawlspace, and how much material the fix requires. A simple reconnection of one separated run usually runs on the low end, while a job that involves multiple leaks, a damaged boot, and an undersized branch run will land at the top of the range.
What affects the price? Accessibility is the biggest factor. Fresno attics vary from walkable open spaces to tight, low-slope spaces where the technician is working on their stomach. Older homes with multiple layers of blown-in insulation are slower to work in. The age of the ductwork also matters: if the flex duct crumbles when touched, what starts as a repair often becomes a replacement, which we’ll quote to you honestly before any work begins.
How do you avoid overpaying? Get the price in writing before the work starts. That’s our standard practice on every job, and it’s the single best protection against bait-and-switch pricing. A free estimate from Linden includes the full inspection, the pressure test, and a written quote that breaks down exactly what we will do and what it will cost. If anything changes during the work, you’ll approve it in writing before we proceed. Call (559) 272-4989 for an exact quote on your specific system.

Frequently Asked Questions About Air Duct Repair in Fresno
Air duct repair is the process of fixing leaks, tears, disconnections, and other damage in the duct system that carries heated and cooled air from your HVAC unit to the rooms of your house. We also offer Sanger Air Duct Repair for residents southeast of Fresno. In Fresno, this usually means sealing joints with mastic, reattaching separated runs, replacing crushed flex sections, and repairing boots at the floor or wall. The goal is to stop conditioned air from escaping into the attic or crawlspace. A properly repaired duct system delivers the right amount of air to every room and reduces the amount of dust and debris pulled into the air stream.
Most air duct repair jobs in Fresno take between 2 and 5 hours to complete, depending on how many leaks we find and how accessible the problem areas are. A single disconnection or a couple of leaking joints is usually a same-afternoon fix. Jobs that involve multiple runs, a full trunk line replacement, or work in a cramped attic or crawlspace can stretch into a full day or, in some cases, a second visit. When we give you the written price, we’ll also give you an honest time estimate.
A standard air duct repair in Fresno runs from $275 to $900, with the majority of jobs falling in the $350 to $550 range. Simple fixes like reconnecting one separated run or sealing a few joints land at the lower end. More involved work, such as replacing a damaged boot or a crushed flex run, lands higher. We put the full price in writing before any work begins, and that price is the price you pay. Call (559) 272-4989 for a free, exact quote on your system.
Yes. We work with Honeywell and Aprilaire air quality products, along with equipment from Nikro and Abatement Technologies. During your duct repair, our technician can evaluate your existing filtration setup and recommend an upgrade if it makes sense for your system. We’ll explain what the product does in plain English: a media filter catches smaller particles than a standard one-inch filter, and an electronic air cleaner actively charges and traps airborne dust. The recommendation comes with a written price, the same as every other part of the job.
We answer the phone with a live person 24 hours a day, 7 days a week. A completely disconnected trunk line or a collapsed duct run in the middle of a Fresno summer is a real urgent situation, and we’ll work to schedule you as quickly as our schedule allows. Call (559) 272-4989 at any hour and a real person will pick up. If we can’t get to you the same day, we’ll give you an honest answer about when we can, not a runaround.
Every air duct repair from Linden Air Duct Fresno comes with a written guarantee, and the 365-Day Done Right Promise means if a covered repair fails within a year, we come back and fix it at no charge. That’s in writing on every job, not just a verbal promise. If anything we touch during the repair causes a problem, we make it right, no back-and-forth. The guarantee is one of the reasons Marcus Veale has built Linden Air Duct Fresno on the Threshold Group’s reputation since 2004.
You don’t need to do much preparation at all. We’ll need clear access to the attic hatch, the return registers, and the area around the air handler or furnace. If you have fragile items near the registers or the unit, moving them a few feet away is helpful. Pets are fine; we’ll work around them, though we recommend keeping them in a comfortable room if they’re anxious around new people. The technician will wear shoe covers, lay drop cloths where they work, and clean up before they leave.
