Fast, Reliable Air Duct Repair Across Selma
Air duct repair in Selma typically runs $200 – $900 depending on whether we’re sealing a separation, replacing a damaged flex run, or rebuilding a supply plenum. Most jobs are completed in a single visit. If you live in Olympia Hills, Retama Springs, or anywhere else in Selma, we know what’s inside your ducts before we even open the access panel: construction dust, drywall debris, and the fine limestone powder this area is known for. Call (430) 233-7681 and we’ll get a real person on the line, day or night.

Linden Air Duct San Antonio serves Selma homeowners with a straightforward promise. The price goes in writing before work starts, the technician’s name and photo arrive on your phone before we do, and every repair carries a written 365-day guarantee. Selma’s rapid growth means a lot of homes here were built in the last two decades. That creates air duct problems most homeowners never expect from a new house.
Why Linden Air Duct San Antonio Is Selma’s Preferred Air Duct Repair Company
We’ve been fixing ducts in Selma long enough to know this city’s housing stock inside and out. Most of Selma’s single-family homes sit in master-planned communities built within the last 15-20 years. The builders used flexible ductwork. Some of it was installed well. Some of it, frankly, wasn’t. We find kinked flex runs pulling attic insulation, unsealed register boots leaking conditioned air into wall cavities, and trunk lines that were never properly connected at the air handler.
Every Selma repair call gets the Threshold Standard. That means your technician is background-checked, identity-verified, and photo-badged. We send you their name and photo before the visit. When the doorbell rings, they show a photo ID badge at the door. You’ll never wonder who’s walking into your home. That matters here, where new neighbors are still getting to know each other and a lot of households include young kids or older homeowners who are home alone during the day.
Dispatch works from our San Antonio office, and a live person answers the phone 24/7. No voicemail loops. You call, a human picks up, and we schedule your Selma repair for a time that actually works.

Ductwork Repair in Selma
Ductwork repair in Selma is different from what a contractor in an older city might encounter, because so much of the damage we find traces back to the original build. New homes here often leave the construction site with ducts that were never fully cleaned, never fully sealed, and never inspected for the kind of kinks and separations that quietly leak air from day one. Over the next few years, that leaks attic air, pulls in insulation, and forces your AC to run longer.
A typical repair in Selma means camera-inspecting the duct run, identifying exactly where air is escaping or debris is entering, then making the fix to spec. We seal separations at registers and the plenum, replace torn or collapsed flex duct, and secure any connections the builder left loose. Most repairs run $200 – $450 for a single issue, with more involved work like rebuilding a return air chase reaching $600 – $900.
Sealing Leaks and Separations
Most air duct repair in Selma starts with the same discovery: a separation between the duct and the register boot, or between two sections of flex. During the building boom around Retama Springs and Olympia Hills, some crews worked fast. We find gaps sealed with weak tape that’s already peeling. We remove it, mastic-seal the joint properly, and test the airflow.
Flex Duct Repair and Replacement
Builders often use flexible duct for supply runs. When it’s kinked, crushed by attic traffic, or torn by rodents, the fix is usually replacement, not patching. We cut out the damaged section, run new insulated flex to proper length, and strap it so it doesn’t sag or pinch. That restores the airflow the room was supposed to have on day one.
Duct Replacement in Selma
Duct replacement is what we recommend when the existing ductwork is beyond repair: sagging trunks, crushed returns, or flex that’s torn in multiple places and leaking more air than it delivers. In Selma, this shows up most often in homes where construction dust has cemented itself to duct interiors after years of humid summers cycling through the system, and where builder-grade flex was installed too loosely to begin with.
A full duct replacement in Selma typically runs $1,800 – $4,500 for an average single-family home, depending on the number of runs and accessibility. Partial replacement, like redoing the supply side only or the main trunk, lands between $800 and $1,800. You’ll get a written, itemized price before we start. That number is the number. It doesn’t change after the job is done unless your home reveals conditions no one could have seen from the outside, and even then we walk you through it before touching anything.
Supply Plenum Rebuilds
The supply plenum sits above your evaporator coil and distributes air to every vav room. When it’s rusted, crushed, or built with undersized sheet metal, airflow across the whole house suffers. We rebuild it with correctly sized, properly sealed sheet metal so the AC doesn’t fight itself.
Whole-System Replacement
If your home’s ductwork is original to a build that was rushed through Selma’s boom, it may all need to go. We quote the job honestly, replacing everything from the air handler connections to the register boots. The system gets sealed and balanced, not just swapped. We use professional-grade equipment, including Rotobrush agitation tools and HEPA-filtered vacuums, to leave the new ducts clean from the start.

Trusted Brands We Service in Selma
We work with the equipment your builder installed and the brands homeowners upgrade to. That includes air-quality products from Aprilaire, Abatement Technologies, and Guardsman, plus professional extraction and agitation gear from Rotobrush. If you have a Honeywell media cabinet or an Aprilaire filter housing that isn’t sealing correctly, we handle that too. Because we carry common components and replacement parts, we can often complete a Selma repair the same visit without waiting on a parts order that leaves you without airflow for a week.
Common Air Duct Repair Problems We See in Selma Homes
- Drywall and construction dust re-circulating. Builders blow through dozens of homes during a Selma boom cycle, and fine drywall dust settles deep in supply and return ducts. Every AC cycle pushes it back into your bedrooms and living spaces.
- Limestone dust cemented to duct walls. In neighborhoods like Retama Springs, the fine dust from nearby development gets pulled into return ducts and then moistened by Selma’s humid shoulder seasons. It hardens onto interior surfaces, narrowing the air path and forcing your blower motor to work harder.
- Kinked or unsealed flex runs. We regularly find flexible duct that was installed with too much slack or bent at tight angles, often where it passes through attic trusses. That blocks airflow to individual rooms and pulls in attic insulation over time.
- Separated register boots. When a builder seals a boot with cheap tape, it fails within a couple of Texas summers. The gap shouldn’t be there, and it’s leaking conditioned air into the wall cavity every time the system runs.
- Crushed return ducts. Attic traffic during construction and later service work often crushes return flex, especially in Selma’s newer homes where attic space is tight. A crushed return means your system can’t breathe, and your AC gets blamed for the temperature imbalance.

Why New Construction Homes Have the Dirtiest Ducts in Selma
Selma sits directly over the Edwards Aquifer Recharge Zone. That fact changes how we approach every air duct repair in this city. When a technician opens a supply plenum or cuts into a flex run, whatever is inside gets disturbed. If it’s fine limestone dust from the Retama Springs build-out, that dust goes airborne fast. We run HEPA filtration and negative pressure on every repair that involves duct work in Selma, because any particulate we stir up that settles outside the house can eventually wash into the recharge zone through runoff. The aquifer’s right there beneath the soil. We take it seriously.
Here’s the part new Selma homeowners don’t expect: a brand-new house often has the dirtiest ducts it will ever have. Builders don’t usually run a post-construction duct cleaning before you close. The drywall sanding, the floor work, the trim cuts – all of that dust had weeks to settle into the return and supply ducts before your furniture ever arrived. Then your first Texas summer kicks on the AC, and the same motors that should be cooling the house start pushing that dust through every vent.
Our crew was called to a two-year-old home in Retama Springs where the supply registers were blowing a persistent chalky film. We ran a camera inspection and found the main trunk and several supply ducts caked with fine limestone dust from the neighborhood’s original build-out. Using our Rotobrush agitation tools under negative pressure with a HEPA-filtered vacuum, we performed full source removal of the debris, then sealed a small separation at the air handler cabinet to prevent re-entrainment from the attic. That home didn’t need a new system. It needed someone to actually see what was inside the ducts.

FAQs About Air Duct Repair in Selma
Your new home probably doesn’t need repair because it’s old. It needs repair because builders leave ducts unfinished. The flex runs get kinked during installation, register boots get sealed with failing tape, and construction dust fills every return and supply duct before you close. Selma’s building pace means this happens here more than in slower-growing areas. The fix is to inspect the ducts, seal what’s leaking, and clean what the builder left behind. Call (430) 233-7681 and we’ll tell you what’s really in there.
We see fine limestone dust, drywall dust, and blown insulation in the ducts around Retama Springs. Limestone dust isn’t toxic, but it’s an irritant, and for anyone with asthma or allergies it makes symptoms worse. It also narrows the airflow path, makes your AC work harder, and turns into a paste inside humid ducts during Selma’s shoulder seasons. The real concern is that once moisture hits it, it can support mold growth. A professional cleaning with HEPA filtration removes the dust without pushing it into your living space.
No. Builders in Texas are not required to clean the HVAC ductwork or do a post-construction inspection on it before closing. The construction contract typically covers the system working, not the ducts being clean or efficient. That’s why we recommend a camera inspection within the first year, especially in Selma’s newer communities. If we find kinked flex, unsealed boots, or a trunk full of drywall dust, we document it and give you a written price to correct it.
Selma’s summers are hot and humid, and the transition weeks between seasons can be brutal. The moisture in the air condenses inside ducts when cold air moves through warm attic spaces. That condensation turns dry construction dust into sludge, which makes duct walls sticky enough to trap more debris. It also creates conditions where mold can take hold. We fix this by sealing the ducts so attic air can’t enter, then cleaning the system back to bare metal or clean flex with source-removal equipment.
It helps indirectly. The goal is to keep particulates contained, not to send them outside. Any dust we remove gets captured by HEPA filtration and negative pressure in the truck or containment unit, not blown out a window or into the yard. If it doesn’t get into your house, it can’t settle outside and wash into the recharge zone. Selma’s position over the aquifer makes this a real responsibility, and we treat it as part of every job, not an add-on.
We schedule repairs across Selma daily. In most cases we can get to you within a couple of business days, and we can often work with your schedule if you need a specific window. If the system is down and the house is hot, tell the person who answers the phone and we’ll see what we can move around. Call (430) 233-7681 and you’ll reach a human, not a queue.
We cover all of Selma, including Olympia Hills, Retama Springs, and the established streets near I-35 and Lookout Road. The age of the home changes what we look for, not whether we’ll come. Older Selma homes have their own issues: galvanized duct that’s rusted through, returns that were undersized to begin with, and years of accumulated dust from the city’s growth around them.
