We’ve worked on enough homes off Fair Oaks Parkway and along Dietz Elkhorn Road to know what the ductwork looks like in this city. Large footprints, long runs, original flex from the 1980s and 1990s, and return plenums that sit downwind of horse paddocks. Our Duct Repair & Sealing team doesn’t guess. We run a camera, show you what we found, and give you a written scope with a fixed price.
Why CleanRun Air Duct Cleaning New Braunfels Is Fair Oaks Ranch’s Preferred Duct Repair & Sealing Company
We’ve served Fair Oaks Ranch since adding it to our route schedule in our early years, and the pattern is consistent: homeowners here research before they call. They want to see license numbers, equipment brands, and proof the work happened. We publish our credentials and deliver a documented photo record on every visit.
Our Fair Oaks Ranch customers consistently mention the same things in follow-up conversations: the technician arrived in a marked truck and uniform, explained the camera findings without pushing, and the written price matched the final invoice. Haven Standard Clause 1 - Written Price Before Any Work Starts - applies on every job, including the 4,000-6,000 sq ft properties that make up most of the local housing stock.
Crews dispatched to Fair Oaks Ranch carry extra flex duct inventory and mastic sealant rated for the temperature swings common on the Balcones Escarpment. We know which homes near the equestrian centers have return intakes positioned to pull equine dander, and we plan the negative-pressure extraction accordingly. That local knowledge changes what we bring and how we sequence the work.
Tomas Reyes, who leads CleanRun, set the H.A.V.E.N. Standard in 2013 after seeing too many duct cleaning operations that treated documentation as optional. Fair Oaks Ranch homeowners were among the first to respond to that approach. They still are.
Our Duct Repair & Sealing Services in Fair Oaks Ranch
Duct Sealing
Most Fair Oaks Ranch homes lose 20-30% of conditioned air through leaks at trunk connections, register boots, and dried mastic joints. We seal with mastic compound and metal-backed tape, then pressure-test the system to verify the drop. On a 4,500 sq ft home near the golf course, we typically find 15-25 distinct leak points in the original ductwork. Sealing a system this size runs $680-$1,100 in Fair Oaks Ranch, depending on attic access and the condition of the existing metal.
Flex Duct Repair
The original flex duct installed in Fair Oaks Ranch’s 1980s and 1990s builds has reached end of life. We’ve replaced crushed runs above the master suites in homes off Boerne Stage Road and rebuilt collar separations that were dumping cooled air into attic spaces for years. Flex duct repair on a single run runs $180-$340; replacing multiple runs in a large home typically falls between $520-$890. We use new R-6 or R-8 flex with mechanical collars, not zip ties and tape.
Metal Duct Repair
Some Fair Oaks Ranch custom homes used galvanized trunk lines with later flex branches. The metal corrodes at seams, especially where condensation pools during the long cooling season. We cut out damaged sections, fabricate replacements, and seal with mastic rated for HVAC use. Metal repair starts around $420 and scales with the linear footage and access difficulty.
Duct Insulation
Uninsulated or degraded duct runs in Fair Oaks Ranch attics bleed temperature for four to five months of sustained 100°F+ operation. We install foil-faced fiberglass wrap or closed-cell insulation where the existing jacket has torn or compressed. Insulation work on a typical multi-zone system runs $380-$620, and it’s often paired with sealing on the same visit.
Mastic Sealant Application
Mastic is the only sealant we use on metal joints and register connections. Tape alone dries and fails; mastic remains flexible and is rated for the thermal cycling Fair Oaks Ranch ductwork endures. We apply it with a brush at every seam, then photograph the work before closing access panels. This is standard on every sealing job, not an upgrade.
Air Leak Repair
Disconnected runs, blown-out register boots, and pest damage in attics - we find all three in Fair Oaks Ranch homes, especially where original construction used lower-grade materials. We repair the leak, test the zone balance, and document the before-and-after static pressure readings in your job record.

BeforeAfterTrusted Brands We Service in Fair Oaks Ranch
Our trucks stock components from Honeywell, Aprilaire, and Guardsman - brands that publish specifications customers can verify independently. We don’t use generic fittings on Fair Oaks Ranch homes because the system sizes and static pressure requirements here exceed what off-brand parts can handle reliably. If your home has an Aprilaire media filter cabinet or Honeywell zone dampers, we carry the replacement hardware and know the pressure ratings. Parts availability means most Fair Oaks Ranch repairs finish in one visit, not two.
Common Duct Repair & Sealing Problems We See in Fair Oaks Ranch Homes
- Original flex duct separates at collars or crushes against framing. The 1980s-1990s flex runs in Fair Oaks Ranch’s custom homes were installed with minimal support and have sagged or pulled apart over decades. We regularly find disconnected runs dumping conditioned air into attic spaces above the second floor, which explains why upstairs bedrooms never reach setpoint.
- Cedar pollen, caliche dust, and equine dander form compacted coatings inside return plenums. Fair Oaks Ranch sits deep in Ashe juniper country, and its December-February pollen events routinely exceed 10,000 grains per cubic meter. The fine pollen slips past standard 1-inch filters, mixes with crushed limestone dust from caliche driveways and dander from nearby horse paddocks, and forms a dense, sticky mat that chokes airflow across the air handler. Cleaning alone doesn’t fix the underlying leaks that let this material accumulate.
- Dried mastic and failed tape create widespread leakage at trunk connections. The original sealants applied thirty-plus years ago have hardened and cracked. During the four-to-five-month cooling season, with systems running almost continuously, those leaks force the blower motor to cycle on high and never reach equilibrium. Sealing the trunk lines typically drops static pressure and reduces motor runtime measurably.
- Oversized return plenums and long duct runs create pressure imbalances between zones. Fair Oaks Ranch’s 3,000-6,000+ sq ft homes often have multi-zone systems with duct runs exceeding 40 linear feet. Without proper sealing and balancing, the far zones starve while the near zones overcool. We measure airflow at each register and adjust dampers after sealing to correct the distribution.

FAQs - Duct Repair & Sealing in Fair Oaks Ranch
Disconnected or crushed flex duct runs above the second floor are dumping conditioned air into the attic instead of the bedrooms. Cleaning the duct interior doesn’t reconnect a separated collar or restore airflow through a run crushed against a joist. Camera inspection finds the real problem, and flex duct repair or sealing fixes it. Call (830) 549-6847 for a written diagnosis and price.
Yes. Mountain cedar pollen grains are 19-22 micrometers, small enough to pass through standard 1-inch fiberglass filters. During peak season, counts exceed 10,000 grains per cubic meter, and the pollen coats duct interiors throughout the system. The real issue is that pollen accumulation is a symptom of leaks: if your return plenum is pulling unfiltered attic or crawl space air, the pollen load increases dramatically. Sealing the leaks reduces the pollen source, not just the symptom.
The combination of cedar pollen, caliche dust from limestone driveways, and equine dander from nearby paddocks creates a denser, stickier coating than typical suburban dust. We’ve pulled material from Fair Oaks Ranch plenums that required aggressive agitation with Rotobrush mechanical whips followed by negative-pressure HEPA extraction. Standard vacuuming doesn’t dislodge it. The compaction is why we photograph every run: so you can see the difference between surface cleaning and actual debris removal.
Uneven temperatures between zones, a blower motor that runs continuously on high, musty smells at registers, or energy bills that climbed without rate increases all point to duct damage rather than routine soiling. We run a camera inspection as the first step on every Fair Oaks Ranch visit. If the ducts are intact, we clean. If they’re separated, crushed, or leaking at seams, we show you the footage and give you a written repair price. The diagnosis itself is part of the standard visit.
Plan on three to five hours for a full inspection, camera documentation, and repair work on a home this size. We’ll access the attic or crawl space, inspect every trunk line and branch run, photograph the interior of each duct, and test static pressure before and after sealing. You’ll receive a documented photo record showing every run, the written scope of work, and the 365-Day Done Right Promise in writing before we leave. The price we quote is the price you pay.
