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.

AfterTrusted Air Duct Repair Nationwide
Air duct repair fixes the leaks, disconnects, crushed sections, and failed joints that quietly bleed conditioned air into attics, crawl spaces, and wall cavities. A typical repair runs $175 to $480 for a localized fix, while partial duct replacement or resealing larger sections usually lands between $450 and $1,150. Linden Air Duct Cleaning has handled this work since 2004, and every repair leaves with a written price agreed before work starts and a home service guarantee in writing. If your ducts are leaking, the fix is rarely as expensive as the monthly energy loss they create. Call (980) 447-2498 and we’ll walk through what you’re seeing.
HVAC Duct Installation
HVAC Duct Installation means running new conditioned-air pathways from your furnace or air handler to the rooms they serve, sized and sealed for your system’s actual airflow. You need it when a remodel adds square footage, when old ducts are too damaged to justify repair, or when a previous install was undersized from day one. Linden Air Duct Cleaning handles full and partial HVAC Duct Installation with professional-grade equipment from Rotobrush and Nikro, and we quote the job in writing before any material gets ordered. Expect most residential installations to land between $1,800 and $4,500, with complex multi-story retrofits running higher.
Sizing and Airflow Calculations
A duct system that’s too small chokes the blower, drives up static pressure, and shortens furnace life. We measure room-by-room heating and cooling loads before quoting, so the new ductwork matches what your equipment actually needs to move.
Sealed Connections, Not Just Fitted Joints
Every connection gets sealed with mastic or UL-rated tape, not just slipped together. That’s the difference between a system that leaks 20% of its air and one that delivers what your thermostat asks for.
Air Duct Replacement
Air Duct Replacement is the full or near-full swap of your existing ductwork when patching individual sections no longer makes financial sense. Most homes reach that point after 25 to 30 years, after water damage from a roof leak or flood, or after rodents have contaminated the interior beyond cleaning. Linden Air Duct Cleaning walks you through the math honestly: if repair would cost more than 60% of replacement, we tell you plainly and can point you to our Air Duct Repair Maintenance Schedule: What to Do and When. Full-home Air Duct Replacement typically runs $2,500 to $6,500 depending on home size, accessibility, and duct count, and every job starts with a written price.
When Repair Stops Being the Smart Move
Collapsed trunk lines, widespread mold inside insulated flex ducts, and systems with more disconnected joints than connected ones are all signs replacement is the real answer. We show you photos from inside the ducts before recommending anything.
Removal and Disposal Included
Our replacement quotes include removing the old ductwork and hauling it away. You won’t find a separate disposal line item added after the fact, because the price you approve is the price you pay.
Ductwork Repair
Ductwork Repair targets the specific failures that rob your system of airflow: separated joints, punctured flex runs, crushed metal trunks, loose takeoffs, and failed seams. These problems rarely announce themselves loudly, but they show up as hot and cold rooms, rising utility bills, and dust that reappears days after cleaning. Linden Air Duct Cleaning has performed our Air Duct Repair in Los Angeles and nationwide since 2004, and Marcus Veale insists on one rule for every job: show the customer the damage before touching it. Typical ductwork repair runs $175 to $480 for a localized fix, $450 to $1,150 when multiple sections need work.
Finding Leaks Before They Find Your Wallet
We pressurize the system and use diagnostic tools to locate exactly where air is escaping, rather than guessing. That means you pay for the repair you actually need, not a series of hopeful patches.
Flex Duct and Metal Trunk Repairs
Crushed metal trunks can sometimes be pulled back into shape and resealed. Torn flex runs usually need section replacement. We’ll tell you which one you’re looking at and why, with a price for each option before work begins.
Duct Replacement
Duct Replacement, as distinct from full Air Duct Replacement, means swapping out a specific run or branch of ductwork while keeping the rest of the system in place. It’s the right call when one bedroom never gets warm, when a single return line has collapsed, or when a remodel reroutes a wall and the old duct path simply has to move. Linden Air Duct Cleaning quotes Air Duct Repair in Huntington Park and surrounding areas per section, with the full scope laid out in writing before any cutting starts. Branch-run duct replacement typically runs $350 to $900 per run, while trunk line sections run higher due to the larger material and more involved connections.
Partial Replacement Without the Full-System Price Tag
Not every house needs everything replaced. When the trunk line and most branches are sound, we replace only the failed sections and leave the healthy ductwork alone, which keeps the bill honest.
Matching Existing Materials Correctly
Replaced sections need to match the existing system’s material and sizing, or you create airflow imbalances. We match rigid to rigid, flex to flex, and size to actual load requirements, not just whatever’s on the shelf.
Ductwork Installation
Ductwork Installation covers design-and-build of a complete duct system for a new build, an addition, or a gut renovation where no usable existing ducts remain. It starts with a room-by-room load calculation, moves through layout and sizing, and ends with sealed, insulated runs that deliver the airflow your equipment was designed for. Linden Air Duct Cleaning has installed complete ductwork systems for remodels, additions, and replacements since 2004. Whole-home ductwork installation typically runs $2,500 to $5,500 for a standard single-family residence, with larger or more complex layouts scaling up from there.
Design First, Materials Second
We plan the layout before ordering a single length of duct. That means proper trunk sizing, balanced branch runs, and returns placed where they actually pull air back to the system, not wherever was easiest to frame.
Insulation and Code Compliance
Uninsulated ducts in unconditioned spaces condense, sweat, and grow mold. We insulate everything that passes through attics and crawl spaces, and we build to current mechanical code requirements. The inspection passes because the work was done right the first time.
Brands We Service
We work with equipment and components from the major names in the trade, so the brand on your system won’t determine whether we can help. Rotobrush and Nikro are the professional-grade tools our technicians use on site, chosen for their power and reliability when we’re cleaning and preparing ducts for repair.
On the air-quality side, we’re familiar with Honeywell and Aprilaire filtration and humidity products that integrate with residential duct systems. Whether you have those brands or any other make, we can service the ductwork itself. The ducts don’t care what badge the furnace wears, and neither do we.
Signs You Need a Pro Right Now
- Rooms that never reach temperature, no matter the thermostat setting. A properly sealed duct system delivers roughly even air to every register. When one room stays hot in summer or cold in winter while the rest of the house is fine, a disconnected or crushed branch run is the usual suspect.
- Dust returning within days of cleaning, despite a clean filter. Leaks on the return side pull attic and crawl space air directly into your living space, bypassing the filter entirely. That’s unfiltered air moving through your home whenever the blower runs.
- Utility bills climbing without a change in usage. Duct leaks mean you’re paying to heat or cool spaces nobody lives in. The Department of Energy has noted for years that leaky ducts can waste 20 to 30 percent of conditioned air. That’s a real monthly cost, every month, until the leak is fixed.
- Whistling, rattling, or banging from the duct runs. Noise means air is escaping somewhere, or metal is flexing and popping against framing. It’s not a personality quirk of your house. It’s a mechanical problem with a mechanical cause.
- Visible crushed, sagging, or disconnected sections in accessible areas. If you can see duct damage in a basement, crawl space, or garage, what you’re seeing is the part that’s easy to spot. There’s often more you can’t see, and it’s worth having the whole system checked.
Our Process, Step by Step
- 1
You call, a person answers. A live voice picks up, day or night. We listen to what you’re experiencing, ask about symptoms and system age, and schedule a visit at a time that works for you. Before the technician arrives, you’ll receive their name and photo.
- 2
Walkthrough and visual inspection. The technician tours your system with you, checks accessible duct sections, registers, and the air handler, and listens to what you’ve noticed. They show photo ID at the door. No exceptions, ever.
- 3
Written diagnosis and price. We identify the specific failures, show you photos if the damage is visible, and put a firm price in writing for exactly what needs to be done. You approve the number before any tool touches a duct. No surprise invoices, no scope creep.
- 4
The repair, done right. We repair or replace the failed sections using sealed connections and correctly sized materials. The work is done by trained technicians using professional equipment, and we don’t leave until the system holds pressure and delivers airflow as designed.
- 5
Walkthrough and written guarantee. The technician reviews what was done, shows you the finished work, and hands you a written guarantee covering the repair. If the covered repair fails within 365 days, we come back at no charge. That guarantee is in writing on every single job.
How Much Does Air Duct Repair Cost?
Most homeowners pay between $175 and $480 for a localized air duct repair, which typically covers a single disconnected joint, a short flex run replacement, or sealing a failed seam. When multiple sections need work, the job generally runs $450 to $1,150. If damage is extensive enough that replacement makes more sense than repair, expect $2,500 to $6,500 for a full-home swap, or $350 to $900 per branch run when only specific sections need replacing. The variables that move the price are access difficulty (crawl spaces and tight attics cost more in labor), duct size and material, and how many sections have failed.
What you should not pay is a surprise. Some companies quote low over the phone, then discover expensive problems after they’re already in your home. That’s not how Linden Air Duct Cleaning operates. Every job gets a written price before work begins, and the price you sign is the price you pay. Our estimates are free, and they include the diagnostic time, so you know exactly what’s wrong and exactly what it costs to fix before you commit to anything.

Frequently Asked Questions About Air Duct Repair
Air duct repair troubleshooting starts with fixing leaks, disconnections, crushed sections, and failed seals in the ductwork that carries conditioned air from your HVAC system to your rooms. It typically involves resealing joints, replacing damaged flex runs, or repairing metal trunk lines. The goal is to restore proper airflow so your system heats and cools efficiently and your rooms reach the temperature you set.
A localized repair, like resealing a disconnected joint or replacing a short flex run, usually takes 1 to 3 hours on site. Multiple-section repairs or partial duct replacement can take a full day. Larger jobs like complete ductwork replacement typically run 2 to 4 days depending on home size and access. We’ll give you a realistic time estimate with your written quote before work starts.
