How Much Does Air Duct Cleaning Cost in San Antonio, TX? (2026 Price Guide) - Supply duct cleaning typically runs $285 to $480 for a standard single-family home, and most jobs are completed in 3 to 5 hours. We clean the ductwork that carries conditioned air from your HVAC system into your rooms, removing the dust, pet hair, and debris that settles there over time. If you’ve noticed dust collecting quickly on furniture or a musty smell when the AC kicks on, call Mortons Air Duct San Antonio at (903) 354-8393 for a free estimate and a written price before we touch anything.
Supply ducts are the delivery side of your HVAC system. Your air handler pushes cooled or heated air through these metal or flexible channels into every room of the house. Over years of San Antonio summers, they accumulate what your family lives with: dust, pet dander, pollen from live oaks and mountain cedar, and sometimes construction debris from a remodel. Our Air Duct Cleaning in San Antonio service includes supply duct cleaning as part of a full-system clean, but many homes benefit from focused attention on the supply side, especially if only certain rooms have airflow or dust problems.
Paul Adeyemi opened Mortons Air Duct San Antonio in 2005 because he kept hearing the same thing from homeowners: crews showed up late, rushed the job, and left a mess behind. So we do things differently. Every visit includes shoe covers and drop cloths, a written price before work begins, and a photo of the clean-up before we leave. That’s the Cedarwell Care Promise, and it’s how we’ve worked since 2005.

When You Need Supply Duct Cleaning
Most San Antonio homes benefit from supply duct cleaning every 3 to 5 years, but some signs tell you it’s time sooner. Here’s what we see in neighborhoods like Stone Oak, Alamo Heights, and Helotes:
- Dust returns within days of cleaning. If you dust the living room on Saturday and by Wednesday it looks like you skipped a week, your supply ducts are likely releasing accumulated dust every time the AC runs.
- Visible dust or debris at the supply registers. Pop off a vent cover and look inside. Gray fuzz, pet hair, or what looks like fine sand clinging to the duct walls means the supply side needs attention.
- Uneven airflow between rooms. If the bedroom over the garage barely gets air while the kitchen freezes, a restricted supply duct may be the culprit. Years of buildup narrow the passageway your conditioned air travels through.
- Pet hair and dander accumulation. Homes with two or three dogs in San Antonio’s pollen-heavy climate combine pet hair with outdoor allergens. Supply ducts collect both and push them back into the rooms where your family sleeps.
- Post-construction or renovation dust. Drywall dust, sawdust, and insulation particles from a remodel in Castle Hills or Terrell Hills find their way into supply ducts and keep circulating for months after the contractor leaves.
- A stale or dusty smell when the HVAC runs. That odor often comes from what’s inside the ducts, not the filter. A clean filter won’t fix dirty supply ducts behind it.
If any of these sound familiar, we’re happy to come out, take a look with our Video Inspection camera, and give you a written price before any cleaning begins. No pressure, no surprises.
Our Supply Duct Cleaning Process
Before any work starts, we walk through the house with you and explain exactly what we’ll do and what it will cost. Then we protect your home, clean the ducts, and show you the result. Here’s how it works:
- Protect your floors and furniture first. Our background-checked, uniformed technicians put on shoe covers at the door and lay drop cloths from the entry to the HVAC unit and each supply register. Pet areas get extra attention so we don’t disturb bedding or food stations.
- Inspect the supply duct network. We use an inspection camera to check the interior of your supply ducts, looking for buildup, blockages, or damage. This tells us which sections need focused cleaning and whether any registers require removal for access.
- Agitate the duct walls with professional equipment. We connect a Rotobrush or Nikro agitation system to the interior of the supply ducts. Rotating brushes loosen the packed dust and pet hair that a vacuum alone can’t remove, reaching deep into the duct runs.
- Extract debris with negative air pressure. Using professional-grade extraction equipment from Abatement Technologies, we pull loosened debris out of the supply ducts and into a containment system. Nothing gets blown back into your house.
- Clean the supply registers and grilles. Each vent cover gets wiped down or cleaned before it goes back on. If a register is bent or damaged, we’ll point it out and let you know your options.
- Show you the before-and-after and clean up. Before we leave, we take a photo of the cleaned supply ducts and the work area. You’ll see proof of the job, and your floors will look the way they did when we arrived.
Throughout the job, we keep tools as quiet as possible. If a toddler is napping or a nervous dog is crated in the next room, we work around it. That’s part of the Cedarwell C.A.R.E. values we train every technician on.
Supply Duct Cleaning Pricing in San Antonio
How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - San Antonio, TX - Supply duct cleaning usually falls between $285 and $480 for a single-family home with up to 10 supply vents. Larger homes with more vents, two HVAC systems, or heavily soiled ducts can run higher, and we’ll tell you the exact written price before we begin. No add-ons appear on the invoice that weren’t discussed upfront. Here’s a breakdown of typical pricing factors:
- Number of supply vents: Homes with 8 to 10 vents are on the lower end; homes with 14 or more run higher because the duct network is larger.
- Accessibility: Supply ducts in attics in older San Antonio neighborhoods like Monte Vista or Olmos Park can be harder to reach, which affects labor time.
- Level of buildup: Light dust removal costs less than removing years of pet hair, construction debris, or pest residue from duct interiors.
- Flexible versus rigid ductwork: Flexible ducts common in newer subdivisions like Alamo Ranch require careful handling with lower-pressure agitation to avoid damage, which can add time.
Our estimates are free, and the price we quote is the price you pay. Call (903) 354-8393 and we’ll schedule a time that works for your family, including evenings and weekends when available.

FAQs – Supply Duct Cleaning
How much does supply duct cleaning cost in San Antonio?
Supply duct cleaning in San Antonio typically costs between $285 and $480 for a standard single-family home with up to 10 supply vents. Homes with more vents, two HVAC systems, or heavy pet hair buildup fall on the higher end; the written price we give you before the job is the final price. Call (903) 354-8393 for a free estimate specific to your home.
What’s the difference between supply duct cleaning and return duct cleaning?
Supply ducts deliver conditioned air from your HVAC system into your rooms, while return ducts pull air back to the system to be filtered and reheated or recooled. Supply ducts tend to collect dust, pet hair, and debris that get pushed into living spaces, which is why focused supply duct cleaning makes a noticeable difference in how quickly your furniture gets dusty.
How long does supply duct cleaning take?
Most supply duct cleaning jobs in San Antonio homes take between 3 and 5 hours, depending on the number of vents and the level of buildup. We protect your floors and furniture before starting, and we work around nap schedules and pets whenever possible.
Is supply duct cleaning safe for homes with kids and pets?
Yes. We use shoe covers and drop cloths on every visit, keep tools as quiet as we can while a child naps, and choose cleaning methods that don’t blow debris back into your living spaces. Our extraction equipment contains what we remove, and we show you a photo of the clean-up before we leave. Same-day service is available when our schedule allows, call (903) 354-8393 to ask about today’s availability.
