We know Converse’s housing stock. The Summerhill subdivisions off Nacogdoches Road, the tracts along Perrin Beitel Road near the North Pan Am Expressway, the older builds creeping up on Anton Schumann Park Campground - our crews have worked in all of them. These are 1980s-2000s slab homes with fiberglass flex duct laid in attics that hit 130-140°F from May through September. That heat doesn’t just make your AC work harder. It cooks duct liner until it cracks, separates collars at the plenum, and turns mastic sealant brittle. We’re in these attics every week, and we know what Converse ductwork looks like after two decades of South Texas summers.

Why CleanRun Air Duct Cleaning Schertz Is Converse’s Preferred Duct Repair & Sealing Company

We’ve served Converse since adding it to our metro route in 2013. Not a satellite office or a franchise territory - our Duct Repair & Sealing in Converse crews are the same background-checked, uniformed technicians operating under Haven Standard Clause 3: Verified Crews, dispatched from our San Antonio scheduling hub. Every technician is identified by name before arrival, and every job starts with a written price and ends with a Documented Photo Record of every duct run.

Converse customers find us the same way most do: they bought a house, got a pre-listing inspection, or noticed the master bedroom never cools. Then they checked for written pricing, verifiable equipment, and photo documentation. CleanRun delivers all three. Our 365-Day Done Right Promise is backed in writing on every job, not buried in a policy manual. If the seal fails, if the flex separates, if the insulation wrap loosens - we make it right.

We answer calls with a live person, 24/7. No automated queue. No “press 1 for duct repair.” When you call (830) 402-5110, you speak to someone who can schedule a Converse appointment, explain our Free Second Opinion on any written estimate, and confirm that your technician will arrive with a name, a photo ID, and a written scope.

Our Duct Repair & Sealing Services in Converse

Duct Sealing

Converse’s tract-home attics are tight. Dense construction along the Connally Loop and Wurzbach Parkway corridors means metal trunk lines often share plenum space with neighboring units’ return air. A poorly sealed joint doesn’t just leak conditioned air into your attic - it can pull insulation particles and even cross-contaminate with adjacent systems. We seal with mastic sealant rated for 130°F+ attic exposure, not tape that peels in the heat. A typical duct sealing job in Converse runs $280-$420 for a single-story slab home with up to eight duct runs.

Flex Duct Repair

This is the work we do most in Converse. The city’s 1980s-2000s flex-duct systems - built to absorb Randolph AFB’s rotating military population - are now 25-40 years old. Attic heat cooks the fiberglass liner until it cracks at elbows and collars. A Summerhill homeowner near Nacogdoches Road called us after a pre-listing inspection flagged disconnected flex runs in the attic; our tech ran camera inspection through the supply and return ducts, found three flex sections separated at the collars where 130-140°F attic heat had cooked the liner brittle, and re-sealed each joint with mastic sealant before re-insulating the trunks with Guardsman wrap. The seller’s agent got the report same day and the buyer’s inspector signed off on the sealed system. Flex duct repair in Converse typically runs $180-$340 per run, with full replacement at $220-$380 per run depending on length and attic access.

Metal Duct Repair

Older Converse homes and some commercial buildings near Building 100 “Taj Mahal” and the Randolph corridor still have galvanized steel trunk lines. These don’t crack like flex, but they rust at seams, separate at drive cleats, and leak through failed gasket joints. We repair with sheet-metal patches, re-seal with mastic, and insulate with Guardsman wrap to prevent condensation. Metal duct repair in Converse runs $320-$580 depending on trunk length and accessibility.

Duct Insulation

Unconditioned Converse attics destroy insulation. When flex duct liner degrades, the R-value of your ductwork drops to nearly nothing. Your 55°F supply air hits 130°F attic metal before it reaches the register. We re-insulate with Guardsman wrap rated for high-heat environments, sealed at every seam with mastic. Duct insulation in Converse runs $240-$480 for a typical single-story system, with full re-wrap of degraded flex at the higher end.

Common Duct Repair & Sealing Problems We See in Converse Homes

• Flex duct collars baked brittle in unconditioned attics. Converse’s slab homes push all ductwork through 130-140°F attic space. The collar at the air handler connection is the failure point - heat-cycled plastic cracks, the joint separates, and attic insulation particles pull straight into your airstream. We find this in Summerhill homes built 1995-2005 almost every spring.
• Cross-contamination between dense tract-home units. Poorly sealed metal trunk joints in shared plenum spaces leak supply air into ceiling cavities that neighboring units use for return. Your neighbor’s cooking smells, pet dander, or construction dust recirculates through your system. We seal with mastic at every accessible joint.
• Shared dryer vent stacks in apartments and condos. The lint trap isn’t the fire risk - the stack is. Converse multi-family buildings accumulate lint past the trap where unit owners never look. We inspect and clean full stacks with rotary brushes and negative-pressure extraction, documented with before-and-after photos.
• Layered debris from PCS turnover cycles. Converse’s housing was built to turn over with Randolph’s PCS cycle, so duct systems here often show visible strata of different families’ pet hair with zero cleaning between handoffs - a pre-sale duct repair pattern that resurfaces every spring when reassignment orders drop. Camera inspection reveals distinct bands of hair color and density from successive owners.
