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.
Fast, Reliable Air Duct Repair Across Schertz
Air duct repair in Schertz usually means one of two jobs: sealing a gap where a boot has separated from the trunk line, or replacing a section of flex duct that has torn or collapsed in the attic. Most Schertz homeowners call us after noticing a room that never cools properly, a sudden spike in the electric bill, or dust appearing on furniture days after cleaning. We dispatch from our San Antonio metro office and work throughout Schertz weekly, so response time is measured in days rather than weeks. If you suspect a duct problem, call (980) 447-2498 and we will walk through the symptoms with you before scheduling anything.
Why Linden Air Duct Cleaning Is Schertz’s Preferred Air Duct Repair Company
Schertz homeowners deal with a specific set of duct problems, and not every company that shows up knows what to look for. We do. The homes here, particularly the 2000s and 2010s tract builds off FM 3009 and Roy Richard Drive, have ductwork running through attics that bake at 130 to 150 degrees all summer. That heat is why we see so many failed boot-to-trunk connections in this city. The mastic dries and cracks, the foil tape peels, and the joint gaps open. A tech who only cleans registers up top will miss what is happening at the connection. We inspect the full run.
We are part of the Threshold Group family, operating to the Threshold Verified standard since 2004. That means every technician who arrives at a Schertz home is background-checked, identity-verified, and photo-badged. Before the visit, you get the tech’s name and photo. At the door, they show a photo ID. No exceptions. The price is written before any work begins, and every repair carries the 365-Day Done Right Promise: a written guarantee, with a free second visit if a covered repair does not hold. Marcus Veale leads our repair work, and he holds the crew to that standard on every Schertz job.
Answering the phone is a live person, 24 hours a day. Not a voicemail tree. If you call at 6 a.m. or 11 p.m., a human answers. That matters when you are trying to decide whether a burning smell from a vent is dust or something worse.
HVAC Duct Installation in Schertz
HVAC duct installation in Schertz typically becomes necessary when existing attic ductwork has deteriorated past the point where patching makes sense. In this city, that happens more often than homeowners expect. The combination of extreme attic heat, shifting from the area’s expansive clay soil, and the rapid construction pace of the 2000s housing boom means sections of flex duct can kink, tear, or sag until the airflow is compromised. A full installation of new flex duct, insulated to R-6 or R-8, restores the static pressure your system was designed to move.
For a typical single-family Schertz home, HVAC duct installation runs between $1,800 and $3,400 depending on the number of supply runs and the accessibility of the attic. That is a whole-system figure, not a per-vent quote. We give you one flat price per system before work starts. What you see is what you pay.
Full-Duct Replacement
When more than a third of the runs show deterioration, patching becomes a losing game. We replace the affected runs with code-compliant insulated flex duct and seal every connection with mastic, not tape alone.
Selective Run Installation
Sometimes only one or two runs have failed, usually the longest ones that stretch to second-story bedrooms or bonus rooms over the garage. We can install new duct on just those runs and leave the healthy sections in place. The price reflects the actual work, not a blanket upcharge.
Air Duct Replacement in Schertz
Air duct replacement in Schertz usually targets the plenums and trunk lines, the large metal or fiberboard boxes that distribute conditioned air to each room. A failed trunk connection is what we found in that 2012-built home off Randolph Boulevard near the JBSA-Randolph main gate. Attic heat had cooked the mastic at a boot-to-trunk joint until it gaped open. The system was pulling in 140-degree attic air, then trying to cool it. The homeowner was paying to air-condition the crawlspace above the ceiling.
For air duct replacement work in Schertz, homeowners can expect to pay between $1,200 and $2,800 for a partial trunk or plenum replacement on a typical tract home. A full replacement, where both the trunk and all branches come out, runs higher, but we write that number down before starting. No surprises at the end, because the price was agreed before the van pulled up.
Plenum and Trunk Line Repairs
Cracked plenums and separated trunk joints are common in Schertz attics where summer heat cycles stress the sheet metal and mastic. We re-fit the sections, seal with fresh mastic, and wrap with foil tape rated for high heat.
Boot and Collar Replacement
The boot is the metal box that connects the duct run to the register in your ceiling. Collar rings grip the flex duct at each end. In Schertz, we frequently find boots packed with drywall dust and fiberglass from original construction, even in homes that are only a few years old.
Trusted Brands We Service in Schertz
We work on duct systems regardless of the original installer or brand. Our repair kits include materials compatible with what is already in your attic, whether that is standard flex duct from a 2000s Schertz tract build or a higher-end system. We stock sealants, hangers, and replacement sections locally so a Schertz repair does not wait on a parts order from out of state. The equipment we bring to the job includes Rotobrush agitation and extraction tools for debris removal before a repair is sealed, and we specify air-quality products from Aprilaire and Abatement Technologies when the repair calls for filtration or sanitizing at the plenum. For duct cleaning jobs that follow or precede a repair, we use Nikro negative-pressure systems. You call, we show up with the right gear. Call (980) 447-2498 to ask about a specific brand or configuration.
Common Air Duct Repair Problems We See in Schertz Homes
- Gapped boot-to-trunk connections from attic heat. The 130 to 150 degree attic temperatures in Schertz summers bake duct mastic until it cracks. The connection gaps open, and the system silently pulls in unconditioned attic air. You notice a room that never reaches temperature and a dust layer that returns within days.
- Builder debris compacted in duct boot collars. Homes built in Schertz’s 2000s construction boom often never received a post-construction duct cleaning. Drywall compound dust and blown-fiberglass insulation stay packed in the boots, restricting airflow and recirculating fine particles for years.
- Torn or crushed flex duct from attic traffic. Cable installers, pest control visits, and even stored boxes can crush flex duct. In Schertz, where most ductwork runs through low attic clearance, damaged runs are common. A crushed duct reduces airflow to a single room and throws the whole system out of balance.
- Cedar pollen loading on return-air systems. Schertz sits on the eastern edge of the Ashe juniper belt. December through February, mountain cedar pollen counts here are among the highest in the country. That fine pollen coats the return side of the system, including the duct interior, and makes existing leaks and gaps far more obvious.
Pricing for Air Duct Repair in Schertz, TX
Air duct repair in Schertz runs from $350 for a straightforward re-seal of a single boot-to-trunk connection up to $2,800 or more for partial trunk line replacement. The most common repair we quote, a boot re-seal with debris removal, lands in the $350 to $650 range. If we need to replace a length of flex duct, expect to add $150 to $400 per run, depending on length and attic accessibility. Attics here can be punishingly hot, and a difficult access setup adds labor time, which is why we always inspect before quoting. You get one flat price per system, written down before work begins. Call (980) 447-2498 for a free estimate. No per-vent pricing, no bait-and-switch.

FAQs About Air Duct Repair in Schertz
Most Schertz homes with original 2000s-era ductwork will need some form of repair within 12 to 18 years of construction. The attic heat in this part of Texas shortens the life of mastic and tape seals, so a boot connection that was sealed at install can fail a decade later. If your home is over 10 years old and you have never had a duct inspection, it is worth having us take a look. Call (980) 447-2498 and we will schedule an inspection. The inspection is free when we do a repair.
No. We never price by the vent. Every repair in Schertz is quoted as one flat price per system, written before we start. If you get a quote from another company that breaks pricing down per vent, ask them what the total will be. A per-vent price is how a $199 advertised special becomes an $800 invoice while the van is parked in your driveway. Our price is the price, and you see it before we touch a tool.
Yes. On every repair, our techs photograph the damaged connection or run before work starts and after the seal or replacement is complete. You will see the gapped boot, the debris packed in the collar, and the finished sealed joint. These are photos of your ducts in your attic, not stock images. You will have a visual record of exactly what was wrong and what we did to fix it.
Rental homes along Randolph Boulevard and the surrounding streets near JBSA-Randolph turn over every two to three years as military families move on PCS orders. The original builder debris, drywall compound dust and blown-fiberglass insulation, never gets removed because nobody orders a post-construction cleaning between tenants. Many of those homes were built in the 2000s and 2010s, so the ducts have been collecting that debris for a decade or more. We see it consistently in that area. The repair should include debris removal, not just a patch, or the new seal gets re-contaminated within weeks.
It can, but not the way most people assume. Cedar season does not damage ductwork directly. What it does is expose existing problems. Fine cedar pollen from the Ashe juniper belt loads the return side of the system every winter, and if you have a gapped boot connection pulling attic air, the pollen makes the dust and allergy symptoms far more noticeable. Repairing a duct during cedar season often starts with a homeowner who could not figure out why allergy symptoms were worse at home. We repair year-round. Call (980) 447-2498 to talk through what you are experiencing. The estimate is free.
