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-system HVAC cleaning in San Antonio typically runs $450-$850 for a standard single-family home, with most jobs completed in one day. The city’s combination of 100°F+ summers, cedar pollen winters, and flex-duct routed through 150°F attics creates a workload we don’t see in northern markets. We’re CleanRun Duct Repair & Cleaning, and our San Antonio office dispatches crews with Rotobrush and Abatement Technologies equipment to homes from Monte Vista to Stone Oak. Call (726) 600-7155 for a written estimate before any work starts.
Why San Antonio Homes Are Different
San Antonio sits at the southern edge of the Edwards Plateau, ground zero for Ashe juniper pollen that drives the regionally infamous “Cedar Fever” from December through February. While most markets see duct cleaning demand spike in spring or fall, San Antonio HVAC systems pull cedar pollen through return-air grilles all winter, coating duct interiors and recirculating allergens on every heating cycle. This creates a distinct winter demand pattern that doesn’t exist in Houston or Dallas.
The housing stock compounds the problem. Pre-WWII craftsman bungalows in Monte Vista and Lavaca sit alongside massive 1970s-90s tract subdivisions in Stone Oak and the Helotes corridor. Nearly all have ductwork routed through unconditioned attics where summer temperatures exceed 150°F, degrading flex-duct seams faster than in climate-controlled runs. Periodic southwesterly dust events deposit caliche and limestone particulate into return systems, especially where older return plenums leak.

BeforeAfterHVAC Cleaning in San Antonio
San Antonio’s central AC systems run nearly continuously from June through September, cycling enormous volumes of air through evaporator coils and blower assemblies that northern markets never stress this hard. The result is a specific pattern of coil fouling and blower wheel loading we document on every HVAC Cleaning job. Homes built during the 2015-2025 boom in Cibolo and Converse are already showing the same accumulation we used to see only in 20-year systems.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, weak airflow from registers, or a musty smell when the AC first cycles on.
What it costs in San Antonio
Evaporator coil cleaning typically runs $280-$450.
How we do it
We remove the access panel, apply foaming cleaner to the fin pack, rinse with low-pressure water, and photograph the coil 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 registers at startup.
What it costs in San Antonio
Blower assembly cleaning typically runs $220-$380.
How we do it
We pull the blower wheel and housing, clean each vane with a soft brush and vacuum, balance the assembly, and document RPM and amp draw.
What HVAC Cleaning Costs in San Antonio
| Item | Typical range in San Antonio |
|---|---|
| Evaporator coil cleaning | $280-$450 |
| Blower assembly cleaning | $220-$380 |
| Full system cleaning (coil + blower + registers) | $450-$850 |
How do I know my HVAC system needs cleaning, not just my ducts?
If your ducts are clean but rooms still cool unevenly, or you smell mildew at startup, the coil or blower is likely fouled. We inspect both with a borescope and show you the image before quoting. Call (726) 600-7155 for a free inspection.
Can HVAC cleaning fix my high summer electric bills in San Antonio?
A dirty coil can raise energy use 15-30%. Cleaning restores designed airflow, but we measure before-and-after static pressure to prove improvement, not promise it. Call (726) 600-7155 to schedule.
Air Quality & Sanitizing in San Antonio
San Antonio’s position between dry western plains and the humid Gulf Coast creates moisture spikes that foster biological growth in ductwork, especially in homes with oversized AC units that short-cycle and fail to dehumidify properly. The cedar pollen winter and caliche dust summer mean San Antonio ducts harbor a year-round load of particulate that standard cleaning alone won’t address. Our Air Quality & Sanitizing work targets the biological and chemical contaminants that survive mechanical removal.
Mold Treatment
Signs you need it
Visible growth on register boots, a persistent earthy smell, or condensation stains on ceiling drywall below duct runs.
What it costs in San Antonio
Whole-system mold treatment typically runs $650-$1,200 depending on contamination extent and access.
How we do it
We apply an EPA-registered botanical fungistat to affected duct surfaces with a fogging system, then verify with ATP surface testing and include results in your photo record.
UV Light Installation
Signs you need it
Repeated mold recurrence after cleaning, or a family member with documented immunocompromise.
What it costs in San Antonio
UV-C lamp installation at the coil typically runs $380-$650 including the lamp and electrical connection.
How we do it
We mount a 254nm UV-C lamp in the supply plenum upstream of the coil, wire to the blower circuit, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in San Antonio
| Item | Typical range in San Antonio |
|---|---|
| Mold treatment (whole system) | $650-$1,200 |
| UV-C lamp installation | $380-$650 |
| Bacteria sanitizing (per system) | $280-$450 |
Is mold in my ducts common in San Antonio?
More common than in drier climates. Short-cycling AC units in newer homes and attic humidity spikes create conditions we treat monthly in summer. We test before treating and show you the lab result. Call (726) 600-7155.
Does UV light actually work, or is it a gimmick?
UV-C at 254nm kills mold and bacteria at the coil surface where they grow, but it won’t scrub particles from moving air. We install it as prevention after cleaning, not as a substitute. Call (726) 600-7155 to discuss your system.
