AfterFast, Reliable Air Duct Repair Across Houston
Air duct repair in Houston typically runs $350 – $900 for a standard flex-duct replacement run, and $1,200 – $3,400 when multiple runs or the plenum need rebuilding. Most jobs are finished in a single visit, and we stock the common materials Houston homes actually need, so we’re not waiting on a parts truck from across town. We know Houston’s housing stock: the slab-on-grade ranches in Westbury, the 1970s subdivisions off Bissonnet, the post-boom builds along Highway 6. If your attic ductwork is failing, call (980) 447-2498 and we’ll walk you through what you’re looking at over the phone before anyone sets foot in your house.

Houston homeowners call us because we tell them who’s coming to the door before the van pulls up.

Every repair carries a written guarantee, and the price is in writing before any work begins. If a covered repair doesn’t hold, we come back at no charge. That’s the 365-Day Done Right Promise, and it’s written on every job. No exceptions, no fine-print games.
HVAC Duct Installation in Houston
HVAC Duct Installation in Houston means more than hanging flex runs in a hot attic. It means sizing the duct correctly for the air handler, sealing boot connections so humid return air doesn’t condense against drywall, and using materials that won’t break down in a 150°F attic. We install new duct systems in remodeled homes, addition projects, and any Houston house where the original ductboard has reached the end of its life. A typical single-room HVAC duct installation in Houston runs $450 – $900; a full-system install in a 2,000 – 2,800 square foot home generally falls between $2,800 and $5,500 depending on run count and access.
New construction and whole-home remodels
Houston’s building boom means plenty of HVAC contractors, but few who treat duct installation as something that gets sealed and verified, not just stapled. We install with mastic-sealed boots at every connection, and we test supply and return balance when the job’s done. That matters in Houston, where a leaky return plenum pulls attic air into the system year-round.
Replacing failed flex-duct runs
Flex duct in Houston fails faster than the national average. Heat plus humidity plus time equals a brittle inner liner that sheds particles into the air stream. When we replace a run, we run a camera through what’s left of the old one first. That tells us whether the problem is isolated or systemic, and the written estimate reflects exactly what we found.
Air Duct Replacement in Houston
Air Duct Replacement in Houston is what happens when repair no longer makes sense. We’re talking about flex duct that’s collapsed internally, duct board that’s absorbed enough humidity over the years to lose its structural integrity, or boots that are rusted through at the air-handler connection. Many Houston homes built between the late 1960s and early 1990s in neighborhoods like Spring Branch, Westbury, and the Energy Corridor still carry their original flex-duct installations. That’s a 15 – 25 year material running on year 30, 35, or more. Replacement typically runs $1,300 – $4,200 for a multi-run job in Houston.
Partial versus full-system replacement
We don’t push full-system replacement when a partial job fixes the problem. If the return side is solid but three supply runs are shot, we replace three runs and leave the rest. The camera inspection shows us where the damage stops, and the estimate reflects that line. No “while we’re in there” invoice inflation.
Signs your ductwork is beyond repair
When our tech finds the inner liner of a flex duct has turned brittle, or duct board has visible mold growth penetrating the fiberglass matrix, patching it with foil tape is a waste of your money. Houston’s climate makes the failure mode predictable, and we’d rather show you the photo than sell you a band-aid.
For broader context on how we handle these projects, our Air Duct Repair team follows the same written-price and written-guarantee protocol on every single job.
Trusted Brands We Service in Houston
We service and install equipment from the brands Houston HVAC contractors actually specify. That includes Rotobrush and Nikro for professional-grade cleaning and repair tooling, plus air-quality products from Honeywell and Aprilaire where filtration or dehumidification makes sense. Because Houston’s supply houses stock these heavily, parts turnaround is usually same-day or next-day. We carry common flex-duct and duct-board stock on the truck, which means we’re not leaving your attic open overnight waiting on a warehouse run.
Common Air Duct Repair Problems We See in Houston Homes
- Flood-soaked duct board that never dried out. Homes near Brays Bayou, especially Meyerland, took water in 2015, 2016, and 2017. We routinely cut into duct board in these houses and find the interior liner still black with embedded mold years later. Walls and floors got replaced; the duct interiors didn’t.
- Short-cycling oversized AC systems. Houston contractors spec systems for peak Gulf heat, which means the unit cools the house fast but never runs long enough to dehumidify. That leaves moisture pooling at flex-duct runs and boot connections. Mold regrows in homes less than a decade old.
- Attic heat destroying flex duct inner liners. Houston attics hit 140 – 160°F through the summer. That accelerates the breakdown of the plastic inner liner on flex duct, which then sheds particles into the air stream. Original ductwork from the 1970s through early 1990s is past its rated life.
- Disconnected or collapsed return plenums. We find return ducts that have pulled away from the air handler, especially in slab homes where vibration and settling work the connections loose. That pulls 150°F attic air and whatever else is up there straight into your living space.
Pricing for Air Duct Repair in Houston, TX
Expect to pay $350 – $900 to replace a single failed flex-duct run in Houston. Rebuilding a plenum or re-sealing an air-handler boot connection runs $300 – $700. Partial-system duct replacement across multiple rooms lands between $1,300 and $2,800, and a full-system replacement in a typical Houston ranch or two-story typically lands between $2,200 and $4,200, sometimes higher when attic access is tight or the home has more than a dozen runs. The estimate is written before work starts, and it doesn’t change unless we both sign off on a change first. Call (980) 447-2498 for a free estimate on any of this. No per-vent pricing, no bait price that triples when the tech arrives.

FAQs About Air Duct Repair in Houston
Almost certainly yes. In Meyerland and other neighborhoods near Brays Bayou, we regularly find duct board interiors still carrying embedded mold colonies years after the flood. The standing water got inside the ducts, soaked into the fiberglass, and never dried out in Houston’s humidity, even after the walls and floors were remediated. A camera inspection of the duct interior will show you exactly what’s there. If we find colonization, the proper fix is removing and replacing the affected duct runs, not spraying something into them. Call (980) 447-2498 to schedule an inspection.
No. Fogging mists the surface of the duct interior but doesn’t remove the mold colony embedded in the duct board or flex-duct liner. In Houston’s humidity, the colony regrows within a season because the substrate is still there. Real mold remediation in ducts means aggressive source removal: agitation tools that mechanically dislodge the growth, then negative-pressure extraction with HEPA filtration on the vac, or replacing the compromised duct entirely. We do the removal. We don’t sell fogging as a mold fix. For an honest assessment of what your ducts actually need, call (980) 447-2498.
The most common answer in Houston is an oversized AC system that short-cycles. When a system is sized for peak Gulf-Coast heat but runs in short bursts, it never fully dehumidifies the air. That leaves residual moisture sitting in flex-duct runs and at air-handler boot connections, and mold grows there even in newer homes. We also see builder-grade flex duct that was under-supported or improperly strapped, which leads to sagging, kinking, and separation at the boots within a decade. A camera inspection tells us which problem you’re looking at. Estimates are free. Call (980) 447-2498.
That kind of sustained heat accelerates failure in two ways. First, the plastic inner liner on flex duct becomes brittle and fractures, shedding particles into the air stream and losing seal. Second, the adhesive and mastic at boot connections degrades faster, which opens gaps that pull attic air into the system. In Spring Branch and Westbury, where many of the original flex-duct installations from the 1970s through early 1990s are still in service, we’re replacing runs that have been baking in that attic heat for 30 or 40 years. That’s past the 15 – 25 year rated life by a wide margin. Call (980) 447-2498 if you think your attic ducts are reaching that point.
Houston’s Gulf Coastal Plain position keeps relative humidity above 70 – 80% for most of the year, which doesn’t happen in El Paso or even San Antonio. Combined with a cooling season that runs roughly nine months, that means Houston ducts cycle moisture-laden air almost constantly. Plus, the flat, poorly-draining topography means a meaningful share of Houston’s housing stock has experienced flood-water intrusion during events like Hurricane Harvey and Tropical Storm Allison. Drier Texas cities don’t carry that flood-soaked duct board problem at the same scale. Houston’s mold risk is structural, not occasional. For a real fix, call (980) 447-2498.
