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.
Air Duct Cleaning in Terrell Hills, TX
HVAC cleaning in Terrell Hills typically runs $380-$620 for a full system, with most jobs scheduled within a week during peak pollen season. The city’s 1940s-1960s estate homes were retrofitted with ductwork through attic spaces that now exceed 140°F each summer, accelerating debris buildup far beyond what newer construction faces. Call (830) 402-5110 for a written estimate before any work starts.
CleanRun crews serving Terrell Hills document every duct run with before-and-after photography, and every job carries a written price under Haven Standard Clause 1. Our San Antonio office coordinates scheduling and dispatch for the area.
Why Terrell Hills Homes Are Different
Terrell Hills sits as a landlocked enclave of large, upscale single-family homes built largely between 1940 and 1970, most in ranch, colonial, and traditional styles. Central air conditioning arrived after construction, so duct systems were retrofitted through unconditioned attic chases using early sheet-metal or flex duct that has now endured decades of San Antonio’s extreme heat. Attic cavities in these homes regularly reach 140-150°F from June through September, degrading duct liners and loosening accumulated debris.
The neighborhood’s dense canopy of mature live oaks creates a contamination pattern rarely seen in newer subdivisions. Each spring, fine catkin pollen and organic particulate drop directly onto rooftop equipment and return-air intakes. Technicians working Terrell Hills consistently find a distinctive green-tinged organic crust inside return plenums and on the first several feet of supply trunk lines, a signature largely absent across the San Antonio city-limit boundary in less canopied developments. San Antonio’s back-to-back allergen seasons, Mountain Cedar from December through February followed immediately by live oak pollen in March and April, drive residents to run systems heavily precisely when airborne loads peak, flushing material deep into aging ductwork where summer heat bakes it in place.
Our Main Terrell Hills Services
Three services account for most calls from Terrell Hills homeowners. Each has its own dedicated page with full pricing and scope details.
Air Duct Cleaning in Terrell Hills
Full negative-pressure extraction of supply and return duct runs, register to plenum, with rotary brush agitation and HEPA-filtered collection. In Terrell Hills, we regularly encounter retrofitted flex duct that has sagged between attic joists, creating low points where debris collects far beyond normal volumes. Every run is photographed before and after. Air Duct Cleaning in Terrell Hills

Dryer Vent Cleaning in Terrell Hills
Complete vent-line cleaning from dryer connection to exterior termination, with airflow testing before and after. The mature live oak canopy deposits organic material onto rooftop and soffit dryer terminations, accelerating lint matting and exterior blockage. We remove the restriction and verify exhaust velocity meets manufacturer spec. Dryer Vent Cleaning in Terrell Hills

Duct Repair & Sealing in Terrell Hills
Repair of disconnected runs, replacement of degraded flex duct, and aerosol sealant application for remaining leakage. Attic heat in Terrell Hills has caused sealant failure and tape degradation in systems that would still be intact in milder climates. All repair scope is written and priced before work begins.

AfterHVAC Cleaning in Terrell Hills

HVAC cleaning in Terrell Hills addresses equipment that has operated for decades in attic environments hot enough to degrade components prematurely, while pulling air through a canopy that deposits unique organic loads onto coils and blower assemblies. The same retrofitted duct systems that characterize local homes also mean air handlers often work harder to overcome airflow restrictions, concentrating debris on wet evaporator surfaces where it becomes a growth medium. CleanRun’s HVAC Cleaning service documents every component with before-and-after photography under the Haven Standard.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, extended cooling cycles, or musty airflow when the compressor first engages.
What it costs in Terrell Hills
Evaporator coil cleaning typically runs $180-$340 depending on accessibility and contamination level.
How we do it
We remove the blower assembly to access the coil, apply foaming cleaner, rinse with low-pressure water, and capture all runoff with a wet-dry vacuum to protect the drain pan.
Blower Cleaning
Signs you need it
Vibration at startup, uneven airflow from registers, or visible dust ejection when the fan cycles on.
What it costs in Terrell Hills
Blower motor and wheel cleaning typically runs $150-$280.
How we do it
We remove the blower assembly, clean the wheel vanes with compressed air and solvent, lubricate bearings per manufacturer spec, and bench-test balance before reinstalling.
What HVAC Cleaning Costs in Terrell Hills
| Item | Typical range in Terrell Hills |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $150-$280 |
| Full HVAC system cleaning (coil, blower, cabinet) | $380-$620 |

Why does my Terrell Hills system need this more often than my last home?
Retrofitted attic ductwork and the live oak canopy combine to load your system with debris that newer, better-sealed construction simply does not encounter. Call (830) 402-5110 for an exact quote - estimates are free.
Air Quality & Sanitizing in Terrell Hills

Air quality and sanitizing in Terrell Hills targets the microbial growth that thrives in aging duct systems exposed to extreme attic heat and organic pollen loads unique to this canopy-covered enclave. The same green-tinged organic crust technicians find in return plenums can harbor mold and bacteria that standard cleaning alone does not address. CleanRun’s Air Quality & Sanitizing service applies EPA-registered treatments with documented application records.
Mold Treatment
Signs you need it
Visible discoloration on register faces, persistent musty odor after cleaning, or respiratory symptoms that worsen when the system runs.
What it costs in Terrell Hills
Mold treatment for affected duct runs typically runs $280-$450 depending on linear footage and accessibility.
How we do it
We apply an EPA-registered antimicrobial fog through the duct system under negative pressure, with dwell time documented, then HEPA-vacuum all treated surfaces and photograph results.
UV Light Installation
Signs you need it
Repeated mold recurrence after treatment, or a system located in a dark, humid attic space where microbial growth persists.
What it costs in Terrell Hills
UV-C lamp installation at the coil or air handler typically runs $320-$480 including hardware and mounting.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp with sight-glass verification, wire to the blower circuit for automatic operation, and label the unit with lamp replacement date.
What Air Quality & Sanitizing Costs in Terrell Hills
| Item | Typical range in Terrell Hills |
|---|---|
| Mold treatment (per system) | $280-$450 |
| UV light installation | $320-$480 |
| Combined sanitizing package (treatment + UV) | $520-$780 |
Is the treatment safe for my family and pets?
CleanRun uses only EPA-registered antimicrobials applied at labeled concentrations, with documented dwell times and full ventilation before occupants re-enter. The written scope specifies product name and EPA registration number.
How long does UV light installation take?
Most UV installations finish in 90-120 minutes, with the system tested and photographed before we leave. Call (830) 402-5110 for an exact quote - estimates are free.
