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.

AfterFast, Reliable Air Duct Repair Across Denver
Air duct repair in Denver typically runs $250 – $650 for disconnected or crushed sections and $900 – $2,400 for partial duct replacement, depending on how much of the system has failed. Most jobs in older Denver homes involve sealing leaks, reconnecting separated joints, and replacing crushed runs more often than a simple cleaning, because so much of the metro’s housing stock still runs original 1950s – 1970s sheet metal. If your system has a visible hole, a disconnected trunk, or rooms that never reach temperature, call (980) 447-2498 for a written quote before any work begins.
Why Linden Air Duct Cleaning Is Denver’s Preferred Air Duct Repair Company
We’re part of the Threshold Group family and have operated to the Threshold Verified standard since 2004. Every Denver technician arrives background-checked, identity-verified, and wearing a clean, marked uniform. You receive the tech’s name and photo before the visit, and they show a photo ID badge at your door before stepping inside.
Denver homeowners often tell us the same thing: they’ve had a duct cleaning company quote one low figure, then hand over a much larger invoice once the plenum was open. We put the full price in writing before any work starts, every single time. No per-vent add-ons. No surprise line items at the end. The written price is the price.
And every repair we make in Denver is covered by our 365-Day Done Right Promise. If a covered repair fails within a year, we come back and fix it at no charge. That promise is written into the paperwork on every job, not just mentioned during the estimate.
Ductwork Repair in Denver
Ductwork Repair in Denver means finding where air is escaping a system that’s often older than the homeowner. In Harvey Park, Barnum, Athmar Park, and Virginia Village, we regularly see original sheet-metal runs with disconnected joints and crushed sections that a standard clean-and-go visit misses. The telltale sign is a room that stays cold in winter or hot in summer even with the furnace running hard.
Our Air Duct Repair techs start with a camera inspection of the suspect run, then seal disconnected joints with mastic or aluminum tape, patch holes, and support sagging sections. In Denver’s semi-arid climate, sealing is not optional: sub-20% indoor humidity keeps fine dust in suspension, so any leak pulls unfiltered air into the living space constantly.
Sealing Disconnected and Leaking Joints
A duct system that leaks 20% of its air is a comfort problem and a utility bill problem. We test each repaired run with a smoke pencil or pressure check before closing up. Expect to pay $180 – $420 for a typical joint-sealing job in a Denver ranch home, depending on access.
Repairing Crushed and Collapsed Runs
Crushed returns are common in Denver basements where storage piles or a remodel pushed against flex or sheet metal. A collapsed return can drop static pressure at the air handler and shorten furnace blower life. We replace the crushed section and re-support the run properly, usually $300 – $650 for a straight replacement of 10 – 20 linear feet.
Duct Replacement in Denver
Duct Replacement in Denver is the fix when original 1950s – 1970s sheet metal has corroded, separated beyond patching, or is lined with decades of ash and dust that no negative-pressure cleaning can fully remove. In homes across Harvey Park, Athmar Park, and Virginia Village, we find supply plenums packed with a gray-brown layer of wildfire ash over prairie dust, with metal so thin in spots that patching simply creates a new failure point six months later.
We replace what fails, not what a sales script says to replace. A camera inspection shows us exactly which runs are compromised. Expect $900 – $2,400 for a partial replacement in a typical Denver ranch, and more if the trunk line itself is involved. The written price covers the full scope before we touch a tool.
Replacing Original Sheet Metal Runs
Original ducts in a 1962 Harvey Park ranch are 60+ years old. Replacing a 20-foot supply run with new sealed sheet metal takes half a day and runs about $800 – $1,600, including mastic-sealed joints and re-insulation where required by Denver code. We do not re-insulate with duct tape. Ever.
New-Construction Duct Corrections in Central Park
Homes built during Denver’s 2010s boom, especially in Central Park and the western suburbs, often have drywall dust and insulation debris sealed inside ductwork from the original build. The real fix is often a MERV rating upgrade at the air handler plus a camera inspection to verify the install, not another cleaning.
Trusted Brands We Service in Denver
Our Denver crews run Rotobrush agitation tools under negative pressure for extraction work, and we stock replacement components compatible with Nikro and Honeywell air-quality equipment. For homes needing filtration upgrades after a smoke season or during Denver’s brown-cloud inversion months, we work with Aprilaire and Abatement Technologies products to match the right filter media to your system. Because we keep common repair parts in local stock, most Denver jobs don’t wait on a shipped component.
Common Air Duct Repair Problems We See in Denver Homes
- Wildfire ash layered over decades of prairie dust: Denver’s basin traps smoke against the Front Range during seasonal inversions, and that fine PM2.5 gets pulled into duct systems whenever furnaces cycle. We see gray-brown deposits in supply plenums that neighboring plains cities outside the inversion zone simply don’t get.
- Disconnected joints in original 1950s – 1970s sheet metal: Harvey Park, Barnum, Athmar Park, and Virginia Village were built fast after WWII, and much of that ductwork has never been touched. Joints separate, air leaks into unconditioned space, and rooms go cold.
- Crushed returns behind finished basements and remodels: Denver’s 2010s remodel boom left a lot of flex and sheet metal pinched behind new framing. A crushed return raises static pressure and shortens blower life, and no cleaning fixes it.
- Construction debris in new builds around Central Park: Drywall dust and insulation scraps get sealed inside ductwork at the time of build. Homeowners assume it’s a cleaning issue when the real fix is often a filtration upgrade and an inspection of the original install.
Pricing for Air Duct Repair in Denver, CO
A ductwork repair in Denver typically runs $250 – $650 for sealing disconnected joints or replacing a crushed section. Partial duct replacement lands between $900 – $2,400 depending on how many runs are involved and whether the trunk line needs work. What moves the price is access: a run above a finished basement ceiling costs more to reach than one in an open crawlspace. You’ll get a written price for the full scope before any work begins, and that price does not change at the end. Call (980) 447-2498 for a free estimate on your system.

FAQs About Air Duct Repair in Denver
Denver sits in a high-plains basin at the foot of the Rockies. When seasonal temperature inversions settle over the city, they trap wildfire smoke and fine particulate against the mountains, the regional brown-cloud effect. Because many homeowners run their systems in fresh-air mode during shoulder-season smoke events, that ash gets pulled into ducts and lingers. Neighboring plains cities outside the inversion zone don’t accumulate the same layer. Call (980) 447-2498 if you’ve noticed gray-brown dust around your supply registers.
In most original Barnum duct systems we inspect, we find at least one disconnected joint, a crushed return section, or a plenum layered with years of ash and dust. The inspection itself is a camera run through your supply and return trunks, and you see the footage yourself. We quote the repair as a written price before any tool comes out.
Yes. Denver’s semi-arid climate keeps indoor humidity under 20% through most of the heating season, which means fine particulate stays suspended instead of settling. Any repair that doesn’t include proper sealing and negative-pressure extraction risks leaving that dust recirculating. We seal joints, filter properly, and extract under negative pressure so the particulate comes out of the system, not into your living room.
New builds in Central Park and Denver’s western suburbs frequently have drywall dust, insulation debris, and even construction scraps sealed inside ductwork from the original build. The real fix is often a camera inspection to verify the install plus a MERV rating upgrade at the air handler, not another cleaning pass. We walk you through what the camera shows before recommending anything.
Most single-run repairs in Denver take 2 – 4 hours from setup to cleanup. Partial replacement of multiple runs can run a full day. We schedule in a window that respects your day, and you’ll know the written price before work begins. Call (980) 447-2498 to ask about your specific system.
