Fast, Reliable Air Duct Cleaning Across Terrell Hills
Air duct cleaning in Terrell Hills costs between $450 and $1,200 for most homes, depending on how many HVAC systems the house has and how much debris has built up over the years. We’re Cardinal Air Duct San Antonio, and we know Terrell Hills homes run large, often with two or three separate air handlers, which changes how the whole job gets priced. If your ducts haven’t been looked at in years, and you’re noticing dust settling back onto furniture within days of wiping it down, call Omar Haddad and our team at (254) 347-3897 for a free estimate. You’ll get a written price before any work starts, and we’ll actually show you what’s inside your ducts before you spend a dollar.
Why Cardinal Air Duct San Antonio Is Terrell Hills’s Preferred Air Duct Cleaning Company
Terrell Hills is a neighborhood where work gets judged quietly and referrals travel fast. Our technicians have been inside enough homes off Elizabeth Road, Garraty Road, and along the streets near Terrell Hills Elementary to know what that means for how we show up. Uniformed, background-checked, and driving a truck stocked with professional equipment, not a rented shop-vac on wheels. Homeowners here don’t want a four-hour arrival window and a technician who hasn’t been told which door to knock on. They want to know the name of the person coming, when they’ll arrive, and what the job costs before anything gets opened up. That’s The Relay Standard we operate under, and it’s built for exactly this kind of customer.
Part of the Relay Home Co. family, we’re held to The Relay Visibility Guarantee: a live trackable arrival time, before-and-after photos of the actual work, and a digital invoice you can pay from your phone. Omar Haddad runs our team with a simple rule: if the work isn’t right, we come back. The 365-Day Done Right Promise covers every job, no exceptions, no fine print. If your ducts aren’t cleaned correctly within a full year, we return and correct it at no charge. That’s the kind of accountability Terrell Hills homeowners expect, and it’s what we’ve built the business around.

Ductwork Cleaning in Terrell Hills
Ductwork cleaning in Terrell Hills isn’t a one-size-fits-all job. The first thing we do is count your systems. A 1950s custom home near Elizabeth Road might have a main HVAC unit for the original footprint, a second unit added during a renovation, and a third for a converted garage or guest wing. Each system has its own supply and return ducts, its own filter setup, and its own accumulation of dust, pollen, and construction debris. The homes here were mostly built between the 1920s and 1960s, and a lot of them have had additions put on over the decades. That means you can’t just “clean the ducts” as if they’re one connected loop. You have to clean each system, and that changes the pricing, the timeline, and the result.
What does the job actually involve? We use negative-pressure extraction, which means the loosened debris goes straight into a HEPA-filtered vacuum outside the house, not back into your living room. Our crews run Rotobrush rotary brush systems to agitate caked-on dust from duct walls, paired with Nikro HEPA vacuums that capture fine particles down to 0.3 microns. For homes with heavy contamination, we use Abatement Technologies containment units to keep the work area sealed while we clean. Before anything starts, we walk the house with you, open the access points, and show you what we’re seeing. Then we hand you a written price. Not after. Before.
Whole-Home Source Removal
We don’t just vacuum the visible registers and call it done. Source removal means we clean the entire duct run: supply and return plenums, branch lines, trunk lines, and the interior of each register boot. In Terrell Hills homes with long attic runs and undersized original returns, this is where the real filth lives. Our goal is to remove the debris at its source, so it stops recirculating through the house every time the AC kicks on.
Expect the job to take four to six hours for a single-system home and up to a full day for a three-system house. You’ll receive before-and-after photos of each system, so you can see exactly what we pulled out and what the ducts look like afterward. No mystery. No “trust us.” Just documentation.
System-by-System Pricing
Here’s the part that matters. A single-system duct cleaning for an average Terrell Hills home runs $450 to $650 depending on the number of supply and return runs. A two-system home typically lands between $650 and $900. A three-system home, which is common in the larger custom properties around Terrell Hills, runs $850 to $1,200. You’ll get one flat price per system, agreed before we touch anything. No per-vent pricing games, no add-ons at the door.
Air Duct Inspection in Terrell Hills
Air duct inspection in Terrell Hills is what we recommend for any homeowner who’s never had their ducts looked at, or who just bought a home and doesn’t know what’s inside the walls and attic. We run a video inspection camera through the ductwork, showing you live what’s in there: dust build-up, mold, rodent activity, collapsed flex duct, renovation debris, or disconnected runs. The camera doesn’t lie, and we want you to see what we see. An inspection as a standalone service runs $150 to $250, but when you book a full duct cleaning, the camera inspection is included at no extra charge.
Why does this matter in Terrell Hills specifically? Because the age of the housing stock means a lot of the ductwork was installed before modern building standards. Homes from the 1940s and 1950s often have original galvanized steel ducts that have never been opened. Additions from the 1980s and 1990s frequently used flex duct, which can sag, tear, or collapse in the intense attic heat of a Texas summer. A camera inspection finds these problems before they become a $2,000 emergency repair or a winter of breathing attic dust.
Multi-System Verification
If your home has three air handlers, we inspect all three separately. It’s shocking how often a previous duct cleaning company cleaned only the main system and skipped the addition or the converted garage entirely. The homeowner paid for a full-house cleaning and got a partial job. Our inspection records show each system’s condition before and after, so you can verify every run was actually addressed.
Pre-Renovation Documentation
Planning a remodel in Terrell Hills? Have us inspect and clean the ducts before the contractors start cutting walls. Construction dust is abrasive and gets sucked into the return side of the system, coating the blower motor and coil. A pre-renovation inspection gives you baseline documentation and a clean system that won’t be circulating drywall dust through the whole house once the work begins.
Trusted Brands We Service in Terrell Hills
We work with the filtration and air quality brands Terrell Hills homeowners already trust. Our team installs and maintains Aprilaire media filters and Guardsman UV purification systems, and we carry the full line of Honeywell filtration products in our service vehicles. When your system needs a new filter cabinet, a replacement media pad, or a UV lamp, we stock the parts and can typically complete the work the same day. We also run Rotobrush brush systems and Nikro HEPA vacuums as our core cleaning equipment, with Abatement Technologies containment for jobs that require it. You won’t hear us upsell equipment you don’t need. But if your ducts are clean and your air still feels heavy, we’ll tell you honestly what filtration or purification upgrade would actually help, and what wouldn’t.

AfterCommon Air Duct Cleaning Problems We See in Terrell Hills Homes
- Undersized original return ducts pulling attic and crawl space dust. Many pre-central-air Terrell Hills homes have return ducts that were never designed for modern forced-air systems. They draw air from wherever they can find it, including dusty attics and crawl spaces, and push that air into living spaces every time the system cycles.
- Construction debris from decades of remodels and additions. Large custom homes in Terrell Hills have been added onto multiple times since the 1950s. Drywall dust, sawdust, nails, and even food wrappers from long-gone contractors end up in the duct runs and stay there for decades.
- Live oak pollen and organic matter accumulating faster than neighboring cities. The dense tree canopy around Terrell Hills means pollen, leaf fragments, and fine organic dust enter the duct system through returns and gaps. Homes on heavily treed lots often need duct cleaning more frequently than homes in newer developments with younger trees.
- Collapsed or torn flex duct in hot attics. Texas attic temperatures routinely exceed 140°F in summer. Flex duct installed during 1980s and 1990s additions can deteriorate, sag, or tear, pulling attic insulation and hot air into the conditioned space. This is a common finding during our inspections and a major energy drain.

FAQs About Air Duct Cleaning in Terrell Hills
Each HVAC system gets its own quoted price, because each system has its own ducts, returns, and contamination level. A three-system Terrell Hills home typically runs $850 to $1,200 total, with the price split by system based on the number of supply and return runs. You’ll see each system’s price in writing before we start, and we clean all three, not just the main one.
Call (254) 347-3897 and we’ll walk through your home’s layout with you over the phone to give you a working range before we even arrive.
You should receive before-and-after photos of every system we cleaned, a written summary of what was found in each duct run, and a digital invoice payable from your phone. If anything was found that needs attention, such as a torn flex duct or a disconnected return, you’ll get a written description and a separate quote for that repair. We never do repair work without a separate written approval from you.
They can be. Original return ducts from the 1940s and 1950s are often undersized for modern systems and may have never been opened or cleaned. They also tend to pull air from attics and crawl spaces where dust, pollen, and insulation particles gather. We inspect these ducts with a camera before cleaning and use sealed access points to prevent dust from re-entering the system during the job.
Homes under heavy live oak canopy typically need duct cleaning every 3 to 5 years, compared to every 5 to 7 years for homes with less tree coverage. Pollen, leaf fragments, and fine organic dust enter the duct system through gaps and returns, then recirculate through the house. If you can write your name in the dust on your furniture two days after cleaning, your ducts are probably overdue.
Yes. Our technicians arrive in uniform, park in your driveway, and work quietly. We don’t drape signage on the truck or make a production out of the visit. Neighbors will see a clean truck and a professional crew. They won’t hear a loud sales pitch or see equipment scattered across the lawn. If a neighbor asks, we’re happy to give them our card, but we don’t go door to door.
