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 Before & After in San Antonio, TX
We’ve cleaned ducts in San Antonio since 2013, and we’ve learned one thing: homeowners trust what they can see. Every job we finish includes a Documented Photo Record, before and after, inside every duct run. Below are representative projects showing what professional negative-pressure extraction actually looks like, not marketing promises.
Recent Transformations
Single-Story Ranch in Leon Valley - Complete System Restoration
The homeowner called after noticing dust reappearing on furniture within 24 hours of cleaning. Our camera showed a half-inch mat of debris at the plenum inlet (the main distribution box where heated or cooled air first enters the duct network) and compacted buildup through every trunk line. We performed negative-pressure extraction, which pulls loosened debris out of the system rather than pushing it deeper, using a Rotobrush with HEPA filtration. The after photos showed bare galvanized steel at the plenum and clean duct runs to all eight registers. The customer received the full photo record, dated and labeled by room, as part of the standard job deliverable.
Alamo Heights Two-Story - Post-Renovation HVAC Cleaning
A 1960s home in Alamo Heights had undergone three months of kitchen and bathroom renovation without duct sealing. Drywall dust, tile grit, and fiberglass insulation fragments had settled throughout the supply and return system. The camera showed a 3-inch debris build-up at the first elbow (the angled fitting that redirects airflow between floors) and visible particulate coating the evaporator coils. We cleaned the full duct network, then serviced the air handler cabinet and coils with Nikro contact tools. The after documentation showed clean coils and zero visible construction residue in the photographed runs. Haven Standard Clause 1 applied: the written price of $340 for the complete system was agreed before any panel came off.
Terrell Hills - Dryer Vent Cleaning After Fire Department Warning
The San Antonio Fire Department had flagged this Terrell Hills home during a routine safety outreach, noting extended dryer cycle times as a lint blockage indicator. Our inspection camera found a nearly complete obstruction 22 feet up the vertical vent run, with compressed lint reducing airflow to approximately 15% of capacity. This is a genuine fire hazard; dryer lint is highly combustible and the restricted airflow causes overheating. We used a Nikro rotary brush system with reverse airflow to break up and extract the compacted material. The after photo showed a clean 4-inch galvanized vent with unrestricted light visible from the rooftop termination. The customer received the photo record and a written airflow verification note.
Stone Oak - Duct Repair and Sealing With Cleaning
A Stone Oak homeowner reported uneven temperatures: the master bedroom ran 8 degrees warmer than the thermostat setting while utility bills climbed 30% year-over-year. Our inspection found a collapsed section of flex duct (the insulated flexible tubing common in attic installations) in the return path, plus disconnected joints leaking conditioned air into the attic space at 120°F summer temperatures. We replaced the damaged flex run with properly sized and supported duct, sealed all joints with mastic (a brush-applied sealant that outperforms tape for longevity), then cleaned the restored system with Abatement Technologies negative-pressure equipment. The after photos showed sealed joints with dated verification marks and clean duct interiors. The written scope and price, $420 for repair plus cleaning, was delivered before work began under Haven Standard Clause 1.
Live Oak - Air Quality and Sanitizing for Allergy Management
A family in Live Oak had pursued medical allergy testing without identifying environmental triggers; their pediatrician suggested evaluating the HVAC system. Our camera inspection showed moderate debris accumulation plus visible microbial staining at the condensate pan and first few feet of return ductwork, common in San Antonio’s high-humidity climate where condensation creates favorable conditions for biological growth. We completed full mechanical cleaning with Honeywell HEPA-contained equipment, then applied Guardsman EPA-registered antimicrobial treatment to the cleaned surfaces. The after documentation showed absent staining and a written treatment record with product specification sheet included in the job deliverable. The customer paid the written price of $380 agreed upfront; no additional services were proposed on-site.
North Central - Older Home With Original Metal Ductwork
This 1978 North Central home still had its original galvanized steel ductwork, never cleaned in 45 years of occupancy. Previous owners had operated with unsealed return air pathways, drawing attic air through gaps around the duct boots (the metal fitting that connects duct to floor or wall register). The result was layered accumulation: dust, insect debris, and fragments of degraded duct liner visible on camera. We used Abatement Technologies portable negative-pressure units with contact agitation tools sized for the 6-inch and 8-inch metal runs. The after photos showed bare metal with manufacturing stamps still legible, a detail we capture specifically to demonstrate complete debris removal. The $290 written price covered the full system; the customer received 34 dated before-and-after images across 12 duct runs.
