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.

We know Universal City’s housing stock. The mid-century ranches near Pat Booker Road, the original base housing off Schneider Road, the newer builds in the Olympia subdivision – we’ve cleaned ducts in all of them. We understand the difference between galvanized steel trunks from 1965 and flex duct runs installed in 2015, and we adjust our approach accordingly.
Ductwork Cleaning in Universal City
Ductwork Cleaning in Universal City means more than blowing compressed air through a register. In this market, it often means addressing decades of accumulation in 50-year-old galvanized systems, plus the sealing work that keeps them clean after we leave. A typical residential Ductwork Cleaning in Universal City runs $350 – $550 for a single-system home, with larger homes or commercial properties ranging $450 – $650. Commercial systems start around $600 and scale with square footage and access difficulty.
Our process starts with a visual and camera inspection. We use Rotobrush rotary brush systems to agitate debris off duct walls, coupled with Nikro negative-air machines that pull the dislodged material out of your home entirely. This isn’t a shop-vac job. Negative-air method means the ductwork is placed under vacuum while we work, so dust and contaminants exit through our filtration equipment rather than settling in your living space.
What We Find in Older Systems
In the ranch homes near Randolph AFB, we regularly pull out layers of fine dust, insulation fibers, and occasional pest debris that have been accumulating since the Johnson administration. The original galvanized steel ductwork in these homes was never designed for the air conditioning loads we put on them today. Condensation has caused rust and pinhole leaks for decades. A standard clean without addressing those leaks just recontaminates the system within months.
Sealing as Part of the Clean
That’s why our Ductwork Cleaning often includes duct sealing with mastic and mesh. We price this separately and in writing before we start. Sealing pinhole leaks and closing gaps at trunk connections is what makes the cleaning last. Without it, you’re paying to have the same problem again next year.
Air Duct Inspection in Universal City
Air Duct Inspection in Universal City is where we separate a simple cleaning job from one that needs repair work to be worth doing. A typical camera inspection runs $150 – $250 as a standalone service, though we waive this fee when you proceed with a full cleaning. We recommend an inspection first if your home was built before 1980, if you’ve never had your ducts cleaned, or if you’re experiencing persistent odors or uneven temperatures between rooms.
Our inspection uses a high-resolution camera on a flexible rod that travels the full length of your supply and return trunks. We record what we find and show it to you. No guesswork, no scare tactics – just footage of what’s actually in your ducts and what condition the metal or flex material is in.
When Inspection Reveals Retrofit Problems
In Universal City’s base-adjacent neighborhoods, our cameras frequently find return-air chases built into wall cavities with no proper sealing. These chases pull attic air directly into your system. You can clean the ducts perfectly and still smell musty air because the return path is open to insulation, dust, and humidity. We document this, explain it, and price the sealing work separately if you want it done.
Inspection Before Purchase or Move-In
Military families moving in or out of Universal City housing often request an Air Duct Inspection as part of their move checklist. With the turnover rate near Randolph AFB, many homes have been through multiple occupants without any duct attention. An inspection gives you a baseline and a written record of what you’re moving into.
Trusted Brands We Service in Universal City
We clean and service ductwork connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Universal City customers who want to upgrade while we’re on site. Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines – the same tools commercial crews use in hospitals and schools, not hardware-store gear. If your system needs a filtration upgrade after cleaning, we can source Aprilaire media filters or Guardsman UV units with fast turnaround through our San Antonio supply chain. We don’t sell equipment you don’t need, but we keep common items in rotation so you’re not waiting two weeks for cleaner air.
Common Air Duct Cleaning Problems We See in Universal City Homes
- Rusted galvanized ducts with pinhole leaks. The 1955 – 1975 slab-on-grade ranches near Randolph AFB have original steel ductwork that has endured decades of condensation. We find rust holes that blow conditioned air into the attic and pull attic air back into the system. Cleaning alone won’t fix this; sealing with mastic is required.
- Unsealed return-air chases in wall cavities. These older homes were retrofitted for central air using wall cavities as return paths, often without proper blocking or sealing. Our cameras catch insulation fibers and dust being drawn directly from the attic into your breathing air. It’s a Universal City-specific problem that generic duct cleaners miss.
- Crushed or disconnected flex duct in newer subdivisions. Homes along Loop 1604 built since the 1990s often have flex duct lying in unconditioned attics. The combination of South Texas heat and tight attic spaces means previous service work or even pest activity has flattened or separated runs, killing airflow to back rooms.
- Mold and mildew from constant summer operation. Universal City’s humidity and May-through-September cooling season create ideal conditions for microbial growth inside ductwork, especially in homes where the system never gets a break. We address this with source removal and can recommend Guardsman or Aprilaire filtration upgrades to reduce recurrence.

FAQs About Air Duct Cleaning in Universal City
Most can be cleaned and sealed rather than replaced. We’ve restored 1960s galvanized systems that were rusted but structurally sound by performing source removal under negative pressure, then sealing pinhole leaks with mastic and mesh. Replacement becomes necessary only when the metal has deteriorated to the point of collapse or large sections are missing. Call (361) 326-5060 and we’ll inspect yours to give you a straight answer.
The smell is likely coming from an unsealed return-air chase or pinhole leaks in the trunk lines, not the ducts themselves. In the base-area ranches, we frequently find wall-cavity returns open to the attic, pulling humid, dusty air directly into the system. A standard cleaning doesn’t seal those paths. We identify this with camera inspection and fix it with mastic sealing – that’s when the smell actually stops.
Every 3 – 5 years for occupied homes, and always between occupants if the previous resident had pets, smoked, or the home sat vacant. With Randolph AFB’s high turnover, many rentals go years without attention. A move-in cleaning gives you a known baseline and removes whatever the previous family left behind. Call (361) 326-5060 to schedule before your move date.
We open the chase at accessible points, remove debris and loose insulation, apply duct sealing mastic reinforced with mesh over gaps and seams, and install proper blocking where the chase meets the attic. The work takes 2 – 4 hours depending on accessibility. We price it separately from cleaning, in writing, before we start. It’s the difference between a temporary fix and a lasting one.
Yes, though it affects how we approach the job. Low-pitch roofs and tight attics are common in the Pat Booker Road and Schneider Road neighborhoods. We use smaller-diameter Rotobrush equipment and portable Nikro negative-air units that fit where standard machines won’t. We also take extra care not to crush existing flex duct runs during access. We’ll tell you during inspection if your attic layout requires special equipment or additional time.
