Trusted Air Duct Repair for Portland Homeowners
Ductwork fails in quiet ways. A joint separates behind drywall, a length of flex duct sags and tears, or a run of old rigid pipe starts leaking at every seam. You notice the symptom long before you see the damage: a room that never gets warm, dust that settles hours after you cleaned, a faint rattle in the wall when the furnace kicks on. Our technicians have up to 8 years of experience finding those failures with Rotobrush and Nikro equipment and sealing them properly, and we don’t just clean your ducts – we fix them when they’re damaged. Same-day repair is often available in Portland, and that’s the point of calling a specialist instead of a generalist.
HVAC Duct Installation
HVAC Duct Installation is the design and fitting of a new duct system to serve an addition, a converted garage, a finished basement, or a home whose original layout never moved air well. You need it when an existing branch can’t reach a room, when a remodel moved walls, or when an older system was sized by guesswork and short-cycles no matter what you set the thermostat to. Steadfast Air Duct Cleaning maps the layout, sizes the runs, and installs ductwork that delivers balanced airflow instead of one hot room and one cold one. Typical installation runs $1,800 to $6,500 depending on how many runs and how accessible the routing is, with the written estimate setting the final price.
Load and Airflow Planning
Before anything is cut, we measure the space each run has to serve and plan the routing to match. That planning step is where a system gets its quiet operation or its whistle, and most of the work happens before a single fitting goes in.
New Runs and Return Additions
Adding supply runs without adding return capacity is one of the most common causes of a noisy, starved system. We size both sides together so the blower has the air it needs to move.

Air Duct Replacement
Air Duct Replacement means removing a failed duct system and putting new ductwork in its place, rather than patching it piece by piece. It’s the right call when the original ducting has deteriorated past repair: collapsed flex runs under a crawlspace, brittle duct board that crumbles when touched, or a layout so poorly designed that no amount of sealing will balance the house. We assess the existing system with Rotobrush and Nikro equipment, document what’s failing, and replace it run by run with ducting sized for your home’s actual airflow. Air duct replacement in Portland typically runs $2,400 to $7,500 depending on system size and access, with the written estimate setting the final figure.
When Repair Stops Making Sense
If three or more sections of a system have failed, patching each one separately usually costs more than replacing the whole run. We’ll tell you honestly which side of that line your ductwork is on.
Access and Routing Challenges
Portland homes sit on a wide mix of foundations, from full basements to tight crawlspaces, and that changes how new ducting gets routed. We plan the path before we start so the install doesn’t turn into a demolition project.
Ductwork Repair
Ductwork Repair covers the targeted fixes that restore a system without replacing it: sealing separated joints, patching torn flex duct, reconnecting crushed runs, and mending the leaks that waste conditioned air inside walls and attics. You need it when one area of the house underperforms, when you hear whistling or rattling at the registers, or when dust appears faster than it should after cleaning. We use professional-grade equipment to find the leaks, then patch and seal them so the repair holds. Ductwork repair in Portland generally falls between $220 and $950 per job depending on how many leaks and how hard they are to reach, and the written estimate sets the final price.
Locating the Leak
A leak you can hear isn’t always the one costing you money. We trace the full run so the fix you pay for is the one that actually helps.
Sealing Materials That Last
Tape and mastic fail differently, and the right choice depends on the duct material and where it sits. We match the seal to the surface so the joint doesn’t open again next season.
Duct Replacement
Duct Replacement is the removal and reinstallation of a specific section or run of ducting that has failed beyond patching, without rebuilding the entire system. It comes up most often with crushed flex duct in a crawlspace, ducting that has soaked up moisture, or a branch that was never sized correctly in the first place. We isolate the bad section, replace it with properly sized ducting, and reconnect it so the system as a whole stays balanced. Duct replacement in Portland usually runs $400 to $1,600 for a single run depending on length and access, with the written estimate setting the final figure.
Spotting a Failed Section
Crushed, kinked, or water-damaged ducting restricts airflow far more than a simple leak does. It’s one of the first things we check when a room never seems to get its share of air.
Matching the Original System
A replacement section has to work with the rest of the system, or it creates a new imbalance. We match sizing and material so the fix integrates rather than fights the existing ductwork.
Ductwork Installation
Ductwork Installation is the fitting of new ducting from scratch where none exists or where the old layout is being abandoned entirely. It applies to new construction, major renovations, and conversions where a room was never ducted at all. Steadfast Air Duct Cleaning handles the layout, materials, and connections, and we work alongside Honeywell and Aprilaire equipment so the new ducting integrates with whatever air quality controls you already run. Ductwork installation in Portland typically runs $1,200 to $4,800 depending on the number of runs and how accessible the space is, with the written estimate setting the final price.
Material Selection
Rigid, flex, and duct board each have a place, and the choice depends on where the run goes and how much it needs to bend. We pick for durability and airflow, not for what’s cheapest to install.
Connecting to Existing Equipment
New ducting has to mate cleanly with your air handler or furnace without choking it. We check the connection point carefully, since a poor transition there undoes good work everywhere else.
Brands We Service
We work around Honeywell and Aprilaire whole-home air quality systems regularly, so we understand how duct condition affects the filtration and humidity control those systems are trying to deliver. When ductwork leaks, the equipment ends up working against itself, and knowing the brand helps us diagnose the whole picture rather than just the duct.
We also use Rotobrush and Nikro equipment on every job, and Abatement Technologies filtration to capture what gets dislodged during the work. Whether you have Honeywell or Aprilaire controls, or any other make, we can help.

- Whistling or rattling at the registers. That noise usually means a restriction or a loose connection somewhere in the run. Left alone, it stresses the blower and wears the system down faster.
- Rooms that never heat or cool properly. A room that stays off-temperature while the rest of the house is fine points to a damaged or disconnected duct serving it. It’s a repairable problem, not something you should live with.
- Dust returning within days of cleaning. If dust settles again quickly, air is likely pulling through a gap in the ductwork rather than the filter. That gap is also pulling in whatever sits around it in the crawlspace or attic.
- Visible damage in an accessible run. Crushed flex duct, torn insulation, or disconnected joints you can see are worth fixing before the damage spreads. Small repairs stay small when they’re handled early.
- Higher energy bills with no clear cause. Leaking ducts push conditioned air into spaces you don’t live in, so the system runs longer to hit the same temperature. Repairing the leaks puts that air back where it belongs.
Our Process, Step by Step
We follow the same sequence on every repair, so you know what’s happening and why at each stage.
- 1
Inspection and diagnosis. We examine accessible ductwork and test airflow at the registers to find where the system is losing air. The findings get explained in plain terms before anything is quoted.
- 2
Written estimate. You get one flat price for the job, agreed before work starts. No per-vent pricing, no surprises once a technician is on site.
- 3
Containment. Abatement Technologies filtration runs during the work to capture what gets dislodged, rather than letting it recirculate through the house.
- 4
Repair or replacement. We seal, patch, or replace the failed sections using Rotobrush and Nikro equipment where cleaning is part of the fix. Each repair is checked as we go.
- 5
Verification and photos. We recheck airflow at the registers and show you before-and-after photos of what we found and what we fixed.
How Much Does Air Duct Repair Cost in Portland?
Air duct repair in Portland typically runs $220 to $950 for a targeted fix, depending on how many leaks there are and how hard they are to reach. A single off-temperature room caused by a disconnected run usually sits at the lower end. Repairs behind finished walls or deep in a crawlspace take longer and cost more. Larger jobs move into replacement territory: replacing a single run of ducting usually runs $400 to $1,600, full air duct replacement typically runs $2,400 to $7,500, and new ductwork installation runs $1,200 to $4,800.
What affects the price most is access, the number of failed sections, and whether the ducting can be repaired or has to come out. To avoid overpaying, ask for a written estimate that names the specific repairs rather than a single lump figure, and be wary of a low number quoted before anyone has looked at the ductwork. Our estimates are free, and we include what the repair covers, what it doesn’t, and before-and-after photos of your own ducts so you can see the work was done. The written estimate sets the final price, and that price is agreed before we start.

Frequently Asked Questions About Air Duct Repair in Portland
Air duct repair is the process of finding and fixing damage in your ductwork: separated joints, torn flex duct, crushed runs, and leaks that waste conditioned air. It’s different from cleaning, which removes buildup, and from replacement, which swaps out failed sections entirely. Most repairs involve sealing or patching specific problem areas rather than touching the whole system.
Most targeted repairs take two to four hours, and larger jobs or full duct replacement can take a day or more. The time depends on how many leaks there are and how accessible the ductwork is. We’ll give you a realistic time estimate with the written quote so you can plan around it.
Air duct repair in Portland typically runs $220 to $950 per job, depending on the number of leaks and how hard they are to reach. Single-run duct replacement usually runs $400 to $1,600, and full replacement typically runs $2,400 to $7,500. The written estimate sets the final price.
