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 Leon Valley, TX
HVAC cleaning in Leon Valley typically runs $320-$580 for a full system, with air quality and sanitizing services adding $180-$420 depending on scope. Most Leon Valley homes we work on were built between 1952 and the late 1970s, meaning their ductwork has endured 45-70 years of near-continuous AC operation through Bexar County’s extreme heat. That age profile changes what we find inside the system and what it takes to clean it properly. Call (830) 549-6847 for a written estimate before any work begins.
Why Leon Valley Homes Are Different
Leon Valley sits on San Antonio’s northwest edge, closer to the Ashe juniper country of the Hill Country than any neighborhood on the east or south side. When cedar pollen season hits from December through February, those plumes reach Leon Valley before they disperse across the broader metro, and they push straight into ductwork that was never sealed to modern standards. The housing stock is remarkably uniform: post-WWII ranch homes built from roughly 1952 through the 1970s, many still running original fiberglass duct board or early flex duct that degrades in the heat and sheds particulates into the airstream.
A high share of these homes cycled through military families rotating through Lackland AFB, so ductwork maintenance was often deferred while kitchens and bathrooms got updated. We regularly open systems that look recently renovated on the outside and find 20 years of accumulated debris at the first elbow. Summers push AC five or more months nearly around the clock, accelerating the breakdown of older duct lining materials, while caliche-laden Hill Country dust works its way in through every gap.

Dryer Vent Cleaning in Leon Valley
Dryer vent blockages are common in Leon Valley’s older ranch homes where original vent routing was often long, convoluted, or terminated in now-obsolete configurations. We clear the full run and inspect termination points for proper exhaust flow. A written price is set before work starts, and the 365-Day Done Right Promise applies.

Before
AfterHVAC Cleaning in Leon Valley

HVAC cleaning in Leon Valley addresses what 45-70 years of continuous operation does to a system: evaporator coils caked with caliche dust and pollen, blowers weighted with debris, condensers choked by Hill Country grit. The components are interconnected - a dirty coil strains the blower, a dirty blower drops airflow across the heat exchanger - so we clean the full assembly, not just the ducts. Our HVAC Cleaning service is built around the documented photo record; you see what was in your system before we discuss what needs to happen next.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or AC running constantly without cooling the house in July.
What it costs in Leon Valley
Evaporator coil cleaning typically runs $180-$340 in Leon Valley, depending on accessibility and contamination level.
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 before and after condition through the access panel.
Blower Cleaning
Signs you need it
Unusual vibration or noise from the air handler, dust puffing from registers at startup, or uneven heating and cooling across rooms.
What it costs in Leon Valley
Blower cleaning and balancing typically costs $140-$260 in Leon Valley homes with standard residential air handlers.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the wheel, and reinstall with torque verification.
What HVAC Cleaning Costs in Leon Valley
| Item | Typical range in Leon Valley |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning and balancing | $140-$260 |
| Full HVAC system cleaning (coil, blower, condenser, air handler) | $320-$580 |
How do I know my HVAC system needs cleaning, not just the ducts?
If your registers blow clean but the house won’t cool below 78 in August, or you hear the blower straining, the problem is likely in the mechanical components, not the duct runs. We inspect the coil, blower, and condenser with the same camera we use for ducts, and we show you before any work is proposed. Call (830) 549-6847 for a written estimate.
Can HVAC cleaning fix my high summer electric bills in Leon Valley?
A dirty coil or blower can raise cooling costs 15-30% by forcing the system to run longer; cleaning restores designed airflow and reduces runtime. We measure static pressure before and after to document the improvement. Call (830) 549-6847 for a written estimate.
Air Quality & Sanitizing in Leon Valley

Air quality and sanitizing in Leon Valley targets what the climate and housing stock produce together: mold in damp evaporator plenums, bacteria in decades-old fiberglass duct board, and cedar pollen that infiltrates through every seam and drives indoor air quality down from December through February. The same age that makes Leon Valley ductwork prone to debris accumulation also makes it prone to microbial growth, especially where original insulation has absorbed condensate over years of continuous AC operation. Our Air Quality & Sanitizing service treats the source, not just the symptom, with equipment from Nikro and Abatement Technologies.
Mold Treatment
Signs you need it
Musty odor when the AC first cycles on, visible dark staining at register openings, or family members with worsening allergy symptoms indoors.
What it costs in Leon Valley
Mold treatment for a residential duct system typically runs $280-$520 in Leon Valley, depending on contamination extent and accessibility.
How we do it
We apply EPA-registered antimicrobial through the full duct network under negative pressure, treat the plenum and coil pan, and deliver before-and-after photos of every treated surface.
UV Light Installation
Signs you need it
Recurring mold or biofilm growth despite previous cleaning, or a system that smells clean for two weeks after service then returns to musty.
What it costs in Leon Valley
UV-C light installation in the plenum or air handler typically costs $320-$580 in Leon Valley, including the lamp and electrical connection.
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 show you the installation point in your photo record.
What Air Quality & Sanitizing Costs in Leon Valley
| Item | Typical range in Leon Valley |
|---|---|
| Mold treatment (full duct system) | $280-$520 |
| UV-C light installation | $320-$580 |
| Combined sanitizing package (mold treatment + UV) | $480-$820 |
Does cedar pollen really get inside my ducts, or is it just coming through windows?
Leon Valley’s position on the northwest edge puts it first in line for Hill Country pollen plumes, and aging ductwork pulls that pollen in through leaks in the return path; we photograph the accumulation at the filter rack and the blower. Sealing the duct system after cleaning stops the infiltration. Call (830) 549-6847 for a written estimate.
How do I know mold treatment worked if I can’t see inside the ducts?
Our Documented Photo Record shows every treated surface before and after; you receive the images as a standard deliverable, not on request. If odor or staining returns within 365 days, Haven Standard Clause 1 applies and we return at no charge. Call (830) 549-6847 for a written estimate.

FAQs About Air Duct Cleaning in Leon Valley

Standard residential duct cleaning and HVAC component cleaning do not require permits in Leon Valley; duct repair or modification that alters the building envelope may need Bexar County review. We handle permit identification as part of our scope assessment and note any requirements in your written price.
We typically schedule within 3-5 business days for standard residential service in Leon Valley; seasonal peaks during cedar pollen season or August heat waves may extend to 7-10 days. We do not promise same-day dispatch - duct cleaning is a scheduled, documented job, not an emergency response.
Most Leon Valley homes from the 1950s-1970s have ductwork in the attic or a partial crawl space; we need access to the plenum and main trunk lines, which are usually there. We protect flooring and surfaces, and technicians are background-checked under Haven Standard Clause 3: Verified Crews, identified by name before arrival.
