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.
Fast, Reliable HVAC Cleaning Across Universal City
HVAC cleaning in Universal City typically costs $380 – $540 for a full system cleaning that includes the evaporator coil, blower assembly, air handler, and duct interior, and most jobs are completed in a single visit. The real variable in Universal City isn’t the cleaning method; it’s the housing stock. A 1960s ranch off Pat Booker Road and a 2005 two-story near Olympia Hills have completely different duct systems, and an honest quote has to account for that before anyone touches a register. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we run professional-grade Rotobrush and Nikro equipment on every Universal City job. Call (737) 727-2314 for a free estimate with a written price before work starts.
Key Takeaways for Universal City Homeowners
- Full HVAC cleaning in Universal City runs $380 – $540 for a typical single-system home, agreed in writing before we start.
- We never quote by the vent. Older military-era homes on Universal City’s IH-35 corridor can have 20+ registers, and per-vent math punishes the homeowner for a layout they didn’t choose.
- Every job includes camera inspection, source removal with HEPA-rated negative pressure, and before-and-after photos of your own ducts.
- The 365-Day Done Right Promise means if the work isn’t right within a year, we return and correct it at no charge.
Why Cardinal Air Duct Cleaning Is Universal City’s Preferred HVAC Cleaning Company
Universal City homeowners call us because we answer the phone, show up in uniform, and hand over a written price before a single duct is touched. Our technicians are background-checked and carry the same professional equipment on every job: Rotobrush rotary brush systems for mechanical agitation, Nikro HEPA-rated vacuums for true negative-pressure extraction, and Abatement Technologies containment units when the job calls for it. That’s not a premium add-on; it’s the baseline. When we clean HVAC systems in Universal City, we drive the same trucks, run the same camera inspections, and follow the same process on a 1962 rancher as we would on a 2005 flex-duct home.
Being part of the Relay Home Co. family means every Universal City appointment runs on The Relay Standard: a live trackable arrival window, before-and-after photo documentation, and a digital invoice you can pay from your phone. Omar Haddad leads our team with one standing rule: if the work isn’t right within 365 days, we return and make it right. No fine print, no prorating. That’s the longest satisfaction window in the trade, and it’s written into every Universal City job we book.
We also understand the local map. Universal City is threaded through by Pat Booker Road, Kitty Hawk Road, and FM 1518, with neighborhoods like Rose Garden Estates, Northview, and the older streets running east toward Randolph AFB. That means our schedulers know that a home off Byrd Boulevard and a home off Universal City Boulevard might have wildly different duct architecture, and our crews plan drive times accordingly without ever overpromising an arrival window.
AC Duct Cleaning in Universal City
AC duct cleaning in Universal City means removing the dust, lint, and microbial film that builds inside your supply and return ductwork, and it is the single most effective way to restore airflow on a Texas cooling system that runs hard from April through October. On Universal City’s older mid-century military housing stock, we commonly find original sheet-metal trunk-and-branch ductwork with 40+ years of accumulated debris; on the 2000s subdivisions east of Kitty Hawk, we more often see flex-duct systems where interior liners have begun to degrade. Both need a camera inspection first. The standard AC duct cleaning for a typical Universal City home runs $380 – $540 for one complete system, one flat price agreed before we start, with no per-vent additions.
How We Diagnose Before We Clean
We run a camera through the main trunk line before any agitation tool goes in. On Universal City’s flex-duct homes, skipping this step risks snagging and tearing the inner liner. The camera tells us the duct material, the branch layout, and whether there’s a collapsed section or a disconnected boot. We only proceed when we know exactly what we’re working with.
Source Removal, Not Just Blowing
Some crews show up with a truck-mounted shop vac and blow out the registers. That leaves the return-side lint pathway intact inside the air handler and blower motor. We run agitation tools from both supply and return ducts while setting negative pressure with Nikro HEPA filtration, so loosened debris goes straight into the vacuum, not back into the living room. The blower motor is the heart of the system, and cleaning past it is the whole point.
Furnace Cleaning in Universal City
Furnace cleaning in Universal City is the winter counterpart to AC duct cleaning, and it matters even in a mild Texas climate because the same blower motor that pushed cooled air all summer is now pushing heated air through the same ductwork. Universal City homes run their furnaces for a shorter season than northern cities, but the heating cycle burns off accumulated dust and sends it through the heat exchanger. A typical furnace cleaning in Universal City runs $380 – $540 for the blower, heat exchanger, and full duct path, and we recommend it at the same time as AC duct cleaning so you’re only paying for one system disassembly.
Blower Cleaning and Motor Health
The blower wheel collects a felted layer of lint and dust on the backside of the fan blades, which reduces airflow and forces the motor to work harder. Our techs measure amp draw before and after cleaning. On the 1962 ranch off Pat Booker Road, our camera inspection found the return duct lined with decades of fine lint and a collapsed inner liner choking the air handler. After we removed the buildup and sealed the liner tear, the blower motor amp draw dropped back into spec. That’s the kind of measurable fix that shows up in lower utility bills and quieter operation.
Heat Exchanger Cleaning
The heat exchanger on a Universal City furnace should be inspected and cleaned as part of any furnace maintenance visit. Dust and hair settle on the exchanger surface and burn off during the heating cycle, and that smell is unmistakable the first time the furnace kicks on in November. A clean exchanger burns clean. We include it in the standard furnace cleaning, not as an add-on.
Trusted Brands We Service in Universal City
We service every major residential air handler and furnace brand in Universal City homes, including Carrier, Trane, Lennox, Goodman, Rheem, and American Standard. We stock common blower wheels, access panel gaskets, and flex-duct connectors in our San Antonio office so Universal City customers aren’t waiting on parts for a simple fix. Our equipment is professional-grade by default: Rotobrush for rotary brush agitation, Nikro for HEPA-rated vacuum extraction, Abatement Technologies for containment, and Guardsman for coil treatment products. If your system takes a Honeywell filter or an Aprilaire media cabinet, we can service and replace those too. One visit, one invoice, one flat price per system.
Common HVAC Cleaning Problems We See in Universal City Homes
- Per-vent pricing on older military homes. Universal City’s original mid-century housing stock runs on trunk-and-branch duct layouts with 20+ registers. Quoting by the vent penalizes homeowners for a duct design they inherited. We quote one flat price per system, always.
- Source removal skipped on the return side. Diesel dust from IH-35 and fine lint from decades of use collect in the return duct first. A crew that only blows out supply registers leaves the air handler and blower motor caked. Our process includes both supply and return ducts with negative-pressure extraction.
- Flex-duct tears from blind agitation. The 2000s subdivisions around Olympia Hills and Rose Garden Estates are built with flex-duct webs. If a crew pushes agitation tools without a camera inspection first, the inner liner can snag and tear. We inspect before we agitate, every time.
- Evaporator coil film reducing cooling capacity. Universal City’s long, humid cooling season means coils develop a biofilm layer that insulates the coil and reduces heat exchange. A dirty evaporator coil can raise your cooling costs by double digits. We treat coils with Guardsman products and document the change with photos.
Pricing for HVAC Cleaning in Universal City, TX
A complete HVAC cleaning in Universal City runs $380 – $540 for a typical single-system home.

FAQs About HVAC Cleaning in Universal City
A Universal City home with normal occupancy and pets needs HVAC cleaning every 3 to 5 years, but homes along the IH-35 corridor with heavy diesel exposure or older homes with decades of accumulated debris may need it sooner. The honest answer is that a camera inspection should decide it, not a calendar. If the return duct shows buildup, it’s time. If it doesn’t, you shouldn’t pay for a cleaning you don’t need. Call (737) 727-2314 and we’ll help you figure out what’s actually there.
No. We charge one flat price per system, agreed in writing before we start. Universal City’s older military-era homes often have 20+ registers on a single trunk-and-branch duct system, and per-vent pricing would unfairly punish the homeowner for a layout they didn’t choose. One system, one price, no per-vent math.
Yes. Every Universal City job includes before-and-after photographs of your own ducts, delivered digitally with your invoice. You see the interior of the supply and return ducts before we start, and the same view after extraction. If it isn’t visibly clean, the 365-Day Done Right Promise gives us a year to return and correct it at no charge.
Yes. We clean the full HVAC path in one visit: evaporator coil, blower assembly, air handler interior, supply and return ducts, and heat exchanger. Bundling AC duct cleaning and furnace cleaning into the same appointment is standard for Universal City homes because the blower motor and ductwork are shared between both systems. Call (737) 727-2314 for a single quoted price that covers both.
We don’t promise same-day service because a proper HVAC cleaning requires a scheduled visit, a camera inspection, and enough time to do source removal correctly. What we do promise is a live trackable arrival window when you book, a written price before work starts, and a live person on the phone 24/7 to answer your call. For scheduling and a free estimate in Universal City, call (737) 727-2314.
