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.

The homes here aren’t standard suburban construction, and the ductwork shows it.
Why Terrell Hills Homes Are Different
Terrell Hills sits inside a pocket of 1940s-1960s custom builds that have been gut-renovated multiple times, each remodel driving drywall dust and blown-in insulation deep into original sheet-metal trunk-and-branch systems. The large, tree-canopied lots and tight construction create well-sealed envelopes where particulates recirculate rather than escape. San Antonio’s January-February Ashe juniper season hits hard here - Terrell Hills’ proximity to Hill Country cedar breaks means pollen loads exceed most metro filters’ capacity, coating duct interiors season after season. Military turnover from nearby JBSA-Fort Sam Houston adds another variable: rental homes routinely change occupants between deployments without duct service, leaving systems loaded with years of accumulated debris.
Our Main Terrell Hills Services
Homeowners in Terrell Hills call us most often for these three services:
Air Duct Cleaning in Terrell Hills
We clean the full duct network - trunk lines, branch runs, and registers - using negative-pressure extraction with Rotobrush and Nikro equipment. In Terrell Hills, we regularly find 3-inch debris build-ups at first elbows in homes that last saw service before a 2019 renovation. Every run is photographed before and after.

Dryer Vent Cleaning in Terrell Hills
Dryer vent blockages in older Terrell Hills homes often involve extended runs through original masonry or retrofitted flex sections crushed during landscaping work. We clear the full line from appliance to termination, test airflow with a manometer, and photograph the interior condition. Dryer Vent Cleaning in Terrell Hills
Duct Repair & Sealing in Terrell Hills
Multi-zone HVAC additions in Terrell Hills have created mismatched networks with dead-leg runs and poorly connected flex sections.

BeforeAfterHVAC Cleaning in Terrell Hills
HVAC cleaning in Terrell Hills addresses systems that run eight to ten months a year, continuously drawing Ashe juniper pollen, live-oak pollen, and fine caliche dust through ductwork never designed for this load. The original 1950s sheet-metal trunk lines, often piecemeal extended during luxury renovations, accumulate debris at joints and elbows where airflow drops. We treat the full mechanical system, not just the ducts - HVAC Cleaning includes every component that moves or conditions air.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, reduced airflow at registers, or AC running continuously without reaching setpoint in July heat.
What it costs in Terrell Hills
Evaporator coil cleaning typically runs $180-$340 in Terrell Hills.
How we do it
We access the coil through the plenum - the main air distribution box - apply foaming cleaner, rinse with low-pressure water, and photograph the fin condition before reassembly.
Blower Cleaning
Signs you need it
Vibration noise at startup, uneven airflow between rooms, or dust puffing from registers when the fan cycles on.
What it costs in Terrell Hills
Blower assembly cleaning typically runs $140-$260 in Terrell Hills.
How we do it
We remove the blower housing, clean the squirrel cage and motor housing with compressed air and solvent, balance the assembly, and test amp draw before reinstalling.
What HVAC Cleaning Costs in Terrell Hills
| Item | Typical range in Terrell Hills |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower assembly cleaning | $140-$260 |
| Full HVAC system cleaning | $380-$620 |
How do I know my HVAC system needs cleaning?
Check for dust accumulation on return registers, musty odors when the fan starts, or temperature stratification between rooms. In Terrell Hills, we often find coils completely occluded by pollen after a heavy cedar season. Call (830) 549-6847 and we’ll inspect with a camera - estimates are free.
Can HVAC cleaning reduce my energy bills?
Yes - a clean coil and blower restore design airflow, reducing runtime. In Terrell Hills’ eight-month cooling season, even a 10% efficiency improvement adds up. We measure static pressure before and after to document the change.
Air Quality & Sanitizing in Terrell Hills
Air quality and sanitizing in Terrell Hills targets the specific load this climate produces: Ashe juniper pollen that penetrates standard filters, mold spores from eight months of condensate production, and construction debris from repeated renovations of 1940s-1960s homes. The sealed envelopes that make these homes efficient also trap particulates at concentrations that aggravate allergies and asthma. We treat the source, not the symptom - Air Quality & Sanitizing includes biological remediation and hardware installation.
Mold Treatment
Signs you need it
Musty odor at startup, visible growth on register boots, or family members with worsening respiratory symptoms in humid months.
What it costs in Terrell Hills
Mold treatment typically runs $280-$520 in Terrell Hills.
How we do it
We apply EPA-registered antimicrobial through the full duct network, treat the evaporator case and drain pan, and run a post-treatment spore trap to verify reduction.
UV Light Installation
Signs you need it
Repeated mold recurrence after cleaning, or chronic allergy symptoms that persist despite filter upgrades and duct cleaning.
What it costs in Terrell Hills
UV light installation typically runs $380-$680 in Terrell Hills.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp in the supply plenum, wire to the blower circuit for automatic operation, and verify irradiance at the coil surface with a meter.
What Air Quality & Sanitizing Costs in Terrell Hills
| Item | Typical range in Terrell Hills |
|---|---|
| Mold treatment | $280-$520 |
| UV light installation | $380-$680 |
| Full air quality package | $480-$920 |
Is UV light worth the cost in Terrell Hills?
Yes, if mold recurs after cleaning or allergies persist through cedar season. The lamp runs continuously, treating the coil and plenum where spores colonize. We install Honeywell and Aprilaire units with a 5-year bulb life.
How long does mold treatment take?
Most residential systems need 4-6 hours of contact time plus drying. We seal the home, run the fan to distribute treatment, and verify with post-treatment sampling. You’ll receive the photo record and lab results as standard deliverables.
