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.

AfterAir Duct Cleaning in San Antonio, TX
Whole-home HVAC cleaning in San Antonio typically runs $350-$650 for a standard single-system residence, with most jobs completed in one scheduled visit. The combination of Hill Country cedar pollen, caliche dust from semi-arid terrain, and 20-40-year-old flex-duct systems in north-side subdivisions means San Antonio ductwork carries a particulate load flat-terrain cities rarely match. CleanRun crews coordinate dispatch from our San Antonio office; call (830) 402-5110 for a written estimate before any work begins.
Why San Antonio Homes Are Different
San Antonio sits at the base of the Hill Country’s Ashe juniper belt, making it ground zero for cedar fever season from December through February. The pollen is extraordinarily fine, slipping through gaps around registers and recirculating through return-air systems. That same pollen season follows seven months of continuous AC operation, from April through October, pulling caliche limestone dust through intake vents. In neighborhoods like Helotes and Leon Valley near the Balcones Escarpment, crews regularly find flex ducts that have partially collapsed after years of thermal expansion in 150°F attics, pulling raw attic air directly into the supply stream. The 1980s-2000s tract-home boom left thousands of slab-on-grade homes with original ductwork now well past rated service life.
Our Main San Antonio Services
Most San Antonio homeowners who call CleanRun start with one of these three jobs.
Air Duct Cleaning in San Antonio
We clean the full supply and return network with negative-pressure extraction, photographing every duct run before and after. In San Antonio, this means addressing both summer caliche buildup and cedar pollen residue that standard vacuums leave behind. Every job includes a written price before work starts and a Documented Photo Record delivered when we finish. Air Duct Cleaning in San Antonio is scheduled by system, not by vent count.
Dryer Vent Cleaning in San Antonio
Lint accumulation accelerates in San Antonio’s hard-water areas where fabric softener residue bonds to duct walls. We remove the full blockage with rotary brushes and verify airflow with a manometer, not a hand wave. The job concludes with before-and-after photos of the vent interior. Dryer Vent Cleaning in San Antonio is quoted as a flat price per run.
Duct Repair & Sealing in San Antonio
Collapsed flex duct, separated boot collars, and failed tape joints are common findings in northwest-side attics. We repair or replace damaged sections and seal the full system with mastic, then pressure-test to verify. The written scope specifies every repair before work begins. Duct Repair & Sealing in San Antonio includes photo documentation of each repair point.

BeforeAfterHVAC Cleaning in San Antonio
San Antonio’s continuous cooling season keeps evaporator coils and blower assemblies under constant load, while cedar pollen and caliche dust coat every surface the air touches. In the 20-40-year-old systems common in Stone Oak and Alamo Ranch, this buildup restricts airflow and strains compressors already working against 100°F-plus attic temperatures. HVAC Cleaning addresses the components a standard duct cleaning cannot reach.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from vents, or AC running continuously without reaching setpoint.
What it costs in San Antonio
Evaporator coil cleaning typically runs $180-$320 in San Antonio.
How we do it
We access the coil through the plenum (the air distribution box), apply foaming cleaner, rinse with low-pressure water, and photograph the fin surface before and after.
Blower Cleaning
Signs you need it
Vibration noise from the air handler, uneven airflow room-to-room, or dust puffing from vents at startup.
What it costs in San Antonio
Blower assembly cleaning typically runs $150-$280 in San Antonio.
How we do it
We remove the blower wheel and motor from the housing, clean each vane with compressed air and solvent, balance the assembly, and document with photos.
What HVAC Cleaning Costs in San Antonio
| Item | Typical range in San Antonio |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower assembly cleaning | $150-$280 |
| Full HVAC system cleaning (coil + blower + cabinet) | $350-$550 |
How do I know my HVAC components need cleaning, not just my ducts?
If your vents blow weakly but the ductwork is clear, or if ice forms on refrigerant lines in summer, the restriction is likely at the coil or blower. We inspect both during every duct evaluation and photograph what we find.
Can HVAC cleaning improve my summer electric bills in San Antonio?
A clean coil and blower can restore airflow efficiency lost to buildup, which reduces compressor runtime during peak cooling months. We measure static pressure before and after so you can see the difference in hard numbers.
Air Quality & Sanitizing in San Antonio
San Antonio’s cedar pollen season deposits allergenic material deep in duct liner, where standard vacuuming cannot reach, and the city’s extended humidity spikes create conditions for microbial growth in attic plenums. In homes with 20-year-old flex duct, the porous liner itself becomes a reservoir. Air Quality & Sanitizing targets biological contamination and residual odor that mechanical cleaning leaves behind.
Mold Treatment
Signs you need it
Musty odor at startup, visible spotting on vent registers, or recent water intrusion into the duct system.
What it costs in San Antonio
Whole-system mold treatment typically runs $400-$750 in San Antonio.
How we do it
We apply EPA-registered antimicrobial through the full duct network using a fogging manifold, with dwell time documented, then HEPA-vacuum all accessible surfaces.
UV Light Installation
Signs you need it
Recurring microbial growth after cleaning, or family members with documented sensitivity to airborne mold spores.
What it costs in San Antonio
In-duct UV-C light installation typically runs $350-$600 in San Antonio.
How we do it
We mount a Honeywell or Guardsman UV lamp in the supply plenum, wire to the blower circuit for automatic operation, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in San Antonio
| Item | Typical range in San Antonio |
|---|---|
| Whole-system mold treatment | $400-$750 |
| UV-C light installation | $350-$600 |
| Bacteria sanitizing (per system) | $250-$450 |
Does UV light actually kill cedar pollen in my ducts?
UV-C targets mold spores and bacteria, not pollen; for cedar pollen, we combine source-sealing of duct leaks with HEPA-grade filtration upgrades. We specify the right approach after inspecting your system.
How long does mold treatment take to complete?
Most residential systems require four to six hours of active treatment plus documented dwell time; we schedule accordingly and provide a written completion report with photos.
