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.

AfterFast, Reliable Air Duct Cleaning Across Castle Hills
CleanRun Duct Repair & Cleaning dispatches crews to Castle Hills from our Dallas-Fort Worth scheduling office, and we’ve learned the rhythm of this small enclave city well. Most calls come from homeowners on streets like Wickford Drive, Ridge Oak, or near the Castle Hills City Hall corridor, and we typically book Castle Hills jobs within a 48-hour window. You can reach us at (830) 549-6847 to schedule a free written estimate, or read on to understand why Castle Hills ductwork is unlike anything you’ll find in newer San Antonio suburbs.
Castle Hills sits inside Loop 410 with a housing stock built almost entirely between 1952 and the mid-1970s. That matters for duct cleaning because these homes run original rigid sheet-metal trunk lines with first-generation fiberglass liner or early flex-duct branches that have cycled through 8-9 months of annual air conditioning for five decades straight. Our Air Duct Cleaning crews don’t just vacuum registers; we document what we find inside every run, photograph it, and deliver a written scope with a fixed price before any work starts.
Why CleanRun Air Duct Cleaning New Braunfels Is Castle Hills’s Preferred Air Duct Cleaning Company
We’ve served Castle Hills homeowners since adding the San Antonio metro to our route schedule, and the pattern is consistent: aging ducts, mountain cedar pollen accumulation, and disconnected runs that waste cooled air into 140°F attics. Our local reputation here rests on what we can show, not claim. Every job includes a Documented Photo Record of every duct run, delivered as a standard deliverable, not an upsell.
Castle Hills customers find us through neighbor referrals and online research, and they stay because we publish our license number, background-check every technician under Haven Standard Clause 3: Verified Crews, and never ask anyone to “call for a quote.” The written price arrives before work starts, every time, under Haven Standard Clause 1. Our 365-Day Done Right Promise is backed in writing on every job, not buried in a policy manual.
Dispatch to Castle Hills is coordinated from our DFW office with local crew routing that keeps travel time minimal. Technicians arrive uniformed, identified by name in advance, and equipped with Rotobrush, Nikro, and Abatement Technologies systems sized for residential trunk-and-branch work.
Our Air Duct Cleaning Services in Castle Hills
Residential Duct Cleaning
Castle Hills homes from the 1950s through early 1970s present a specific challenge: original fiberglass duct liner in attic installations has often delaminated after decades of San Antonio summer heat cycling. Our residential service begins with a video inspection of the plenum and trunk lines to assess liner condition before any mechanical cleaning. If the liner is intact, we perform source removal under negative pressure with HEPA filtration. If it’s deteriorating, we flag it for encapsulation or replacement and document everything. A standard Castle Hills single-family residential cleaning runs $380-$620 for a full system.
Commercial Duct Cleaning
Castle Hills’s small commercial footprint includes medical offices near Northwest Military Highway, retail strips, and professional buildings that share the same aging infrastructure challenge as the residential stock. Commercial systems here often combine original metal ductwork with later retrofit flex additions that have never been properly sealed. Our commercial service includes negative-pressure extraction, register and grille removal, and a written photo record meeting property management documentation requirements. Typical Castle Hills commercial jobs range $850-$2,400 depending on system complexity and access.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, but in Castle Hills they’re only half the story. Many homeowners call after noticing weak airflow to a back bedroom, and our camera often finds a separated collar or crushed flex branch in the attic, not a dirty duct. We clean every supply run with Rotobrush mechanical agitation and negative-pressure extraction, but we also photograph and report any disconnection or seal failure we find. Supply-only cleaning in Castle Hills typically runs $220-$380, though we nearly always recommend evaluating the return side as well.
Return Duct Cleaning
This is where Castle Hills homes hide their worst accumulation. Return-air plenums and filter housings in this area regularly contain a yellowish-gray crust of mountain cedar pollen layered over decades of dust, particularly in homes where filter changes were inconsistent through the 1970s-1990s. The cedar season here, December through February, dumps some of the heaviest allergen loads in the country through exterior intakes. Return duct cleaning requires careful assessment: if the fiberglass liner is delaminating, aggressive brushing can make fiber shedding worse. We inspect first, clean second, and always photograph the before condition. Castle Hills return duct cleaning runs $280-$420 as a standalone service, or is bundled into full system pricing.

Common Air Duct Cleaning Problems We See in Castle Hills Homes
- Delaminated fiberglass duct liner. The original liner in 1950s-70s Castle Hills attics has often separated from the metal substrate and is shedding glass fibers into the airstream. A standard brush-and-vacuum pass without assessment can worsen the problem. We inspect first and recommend encapsulation or liner replacement when needed.
- Disconnected trunk takeoffs and flex connections. Decades of summer heat cycling crack mastic at every joint. Our crews regularly find separated collars dumping cooled air into attic space while bedrooms stay hot. Cleaning without resealing leaves the same leaks pulling attic dust back within months.
- Mountain cedar pollen crust in return plenums. The yellowish-gray buildup unique to this region bakes onto duct liner over years. It’s the largest allergen reservoir in most Castle Hills homes, and it’s invisible from supply registers. Skipping return-side cleaning misses the core problem.
- Crushed or kinked flex-duct branches. Early flex installations in Castle Hills attics have often been damaged by storage activity, rodent pressure, or simple gravity sag over time. Our video inspection catches these before cleaning begins, so we’re not pushing debris deeper into a restricted run.
Pricing for Air Duct Cleaning in Castle Hills, TX
Castle Hills pricing reflects the reality of older ductwork: most jobs require more than surface cleaning. A typical full system cleaning, including supply and return ducts, plenum, and register/grille removal, runs $380-$620 for a standard single-family home. Video inspection adds $85-$120. Duct sealing and reconnection work, which we find necessary on roughly half of Castle Hills jobs, runs $180-$340 per separated or unsealed run. Commercial systems start at $850 and scale with access difficulty and system size.
What moves the price: the condition of original fiberglass liner, the number of disconnected runs found during inspection, accessibility of attic trunk lines, and whether the home has had prior duct modifications. We deliver a written price before any work starts, every time, under Haven Standard Clause 1. No per-vent pricing. No coupon bait-and-switch. Bring a competitor’s written estimate and we’ll provide a Free Second Opinion at no cost.

FAQs - Air Duct Cleaning in Castle Hills
Castle Hills homes were built two to three decades earlier, with original ductwork that has accumulated debris through fifty-plus years of 8-9-month cooling seasons. Stone Oak subdivisions from the 1990s-2000s have newer flex-duct systems with intact liners and fewer decades of mountain cedar pollen baked into return plenums. Your ducts aren’t “dirtier” because of maintenance habits; they’re older and have worked harder, longer. Call (830) 549-6847 and we’ll show you exactly what the camera finds.
Your AC unit and your ductwork are separate systems, and in 1962 Castle Hills homes the ducts are often the hidden problem. We’ve found separated trunk lines dumping cooled air into attics while bedrooms never drop below 78°F, and the homeowner assumed the AC was failing. A video inspection reveals whether the issue is duct leakage, liner deterioration, or actual equipment undersizing. Duct cleaning plus sealing often restores comfort for a fraction of replacement cost. We’ll put both numbers in writing so you can decide.
That’s accumulated mountain cedar pollen, primarily from Ashe juniper trees that dominate the Texas Hill Country around Castle Hills. The December-through-February cedar season dumps extreme allergen concentrations through exterior air intakes, and in homes with infrequent filter changes over past decades, this material bakes onto duct liner during San Antonio’s long cooling season. It’s visually distinctive and chemically different from ordinary household dust. Our return duct cleaning removes this reservoir under negative pressure with HEPA filtration, and we photograph the removal.
It can, if the liner is already delaminating and the crew doesn’t assess it first. That’s why CleanRun begins every Castle Hills job with video inspection of the plenum and trunk lines. Intact liner receives controlled mechanical agitation; deteriorating liner is flagged for encapsulation or replacement before brushing begins. Haven Standard Clause 1 requires us to document liner condition in your written scope and price. We don’t proceed with cleaning that would worsen fiber shedding.
We clean both, and in Castle Hills the return side is usually where the real problem lives. Supply registers are visible and get attention; return plenums and trunk lines are hidden in attics and contain the heaviest accumulation of cedar pollen and decades of debris. Our Full System Cleaning includes every supply run, every return run, the plenum, and the filter housing, with before-and-after photography of each. Cleaning only the visible vents would miss the core reservoir. Full system cleaning in Castle Hills runs $380-$620 with a written price fixed before work starts.
