Trusted Air Duct Cleaning for San Antonio Homeowners
Air duct cleaning in San Antonio typically costs between $350 and $850 for a full residential system, and most jobs are completed in 3 to 5 hours with same-day scheduling available. When dust, pollen, and debris build up in your ductwork, your HVAC system works harder, your indoor air quality drops, and allergy symptoms often flare up — especially during San Antonio’s heavy cedar fever season and the prolonged summer cooling months when systems run 12+ hours daily.

What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Your home’s duct system circulates air through every room, and over years it accumulates dust, pet dander, construction debris, and even mold spores that settled during San Antonio’s humid spring months. Residential duct cleaning addresses the complete network of supply and return lines, boots, and main trunks that connect to your HVAC unit. When Richard Anderson arrives at your San Antonio home, he’ll run a Rotobrush contact-cleaning system through each branch line while a Nikro negative-air machine maintains suction at the plenum — the same dual-system approach we use in medical office cleanings, adapted for your residential layout.
Commercial Duct Cleaning
Commercial buildings in San Antonio — from medical plazas near the Medical Center to retail spaces along Loop 410 — face higher particulate loads due to occupancy density and longer system run times. Commercial duct cleaning requires larger-capacity equipment, coordinated shutdown planning, and documentation for facility managers and insurance carriers. We bring Abatement Technologies HEPA filtration and high-CFM Nikro collectors to commercial jobs, and Richard Anderson personally manages the scope, timeline, and post-cleaning verification so your maintenance team has clear records.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces, which means any contamination here delivers directly to where you breathe and sleep. Supply duct cleaning focuses on the branch lines, registers, and diffusers that distribute cooled air during San Antonio’s brutal July and August stretches when your system runs continuously. We remove each vent cover, hand-clean the boot and first few feet of line, then follow with mechanical brushing and vacuum extraction to the main trunk — because surface dusting at the register misses 90% of the buildup.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit for reconditioning, making them the primary collection point for airborne debris — especially in San Antonio homes with hardscaped yards that generate fine caliche dust during dry spells. Return duct cleaning tackles the larger-volume trunk lines, filter grilles, and often the return air plenum where the heaviest accumulation occurs. Richard Anderson inspects these areas with a borescope before cleaning, since returns often harbor the surprises: construction debris from original build-out, pest activity, or filter bypass damage that explains why your system never seemed to perform right.
Full System Cleaning
A full system cleaning addresses every component in the air pathway: supply ducts, return ducts, trunk lines, plenums, and the HVAC cabinet itself including blower assembly and evaporator coil access points. This is what most San Antonio homeowners actually need when they call for “duct cleaning” — and it’s what we recommend when a system hasn’t been serviced in 5+ years or after any major renovation. We coordinate the full sequence so no section gets missed, and we finish with a pressure-balanced airflow test to confirm your system isn’t fighting itself with restrictions.
Video Inspection
Video inspection lets you see inside your ductwork before we start cleaning — and after, so you know the job was done thoroughly. Richard Anderson feeds a high-resolution borescope through the system, capturing footage of buildup patterns, damage, disconnected joints, or microbial growth that might change our recommended approach. In San Antonio’s older neighborhoods like Alamo Heights and Terrell Hills, we regularly find original galvanized ductwork with rust scaling or asbestos tape remnants that require modified handling; video documentation protects you and guides our work.

Brands We Service for Air Duct Cleaning
We’ve cleaned ductwork connected to virtually every major HVAC brand installed in San Antonio homes over the past two decades. Carrier and Trane systems dominate newer construction in Timberwood Park and Helotes, and we’ve serviced hundreds of both — we know their plenum configurations, filter rack designs, and the specific access points that make thorough cleaning possible without system damage. Lennox and Rheem units are common in the established neighborhoods inside Loop 1604, and we stock compatible access panels and sealants for these systems so we’re not improvising on your job.
Whether you have Goodman, York, American Standard, Bryant, or any other make, we can help. Richard Anderson’s 17 years of focused duct cleaning experience means he’s encountered the quirks of virtually every manufacturer’s installation style in the San Antonio market — from the compact horizontal attics common in Windcrest and Kirby to the crawlspace setups we see near Lakehills. The brand on your outdoor unit matters less than the condition of the connected ductwork, and that’s where our specialized equipment and owner-led attention make the difference.
Signs You Need Air Duct Cleaning Right Now
- Visible dust puffing from vents when the system starts. That gray plume you notice when the blower first kicks on isn’t normal — it’s accumulated debris in the ductwork breaking loose and entering your living space. In San Antonio, where caliche soil and pollen loads are high, this typically appears within 3 to 5 years of a previous cleaning, sooner if your filter maintenance has been inconsistent.
- Uneven heating or cooling between rooms. When one bedroom stays stuffy while another freezes, restricted airflow from duct buildup or partial blockages is often the culprit. We’ve traced this complaint to collapsed flex duct in San Antonio attics where summer heat degradation weakened the material, or to significant accumulation in return branches that starves the system of balanced airflow.
- Allergy symptoms that worsen at home but improve elsewhere. If you’re reaching for antihistamines more in your living room than your office, your ductwork may be harboring pollen, dust mite debris, or microbial growth that’s recirculating with every system cycle. San Antonio’s cedar fever season from December through February makes this especially noticeable, as pollen infiltrates through intake vents and settles in returns.
- Unexplained increase in energy bills without rate changes. When your HVAC system works against restricted ducts, it runs longer cycles to achieve thermostat setpoints — and in San Antonio’s 100°+ summer stretches, that extra runtime shows up fast on your CPS Energy bill. We’ve measured 15% to 25% airflow improvement post-cleaning on systems that hadn’t been serviced in 7+ years, with corresponding efficiency recovery.
- Musty or stale odors when the system operates. Odors that intensify when the blower runs usually indicate microbial growth on debris buildup inside the ductwork, not just a dirty filter. San Antonio’s humidity — especially during May and October shoulder seasons when systems cycle on and off frequently — creates condensation points in ducts that support this growth if organic material is present.
Our Air Duct Cleaning Process — Step by Step
- 1
Pre-cleaning inspection and video documentation. Richard Anderson arrives with the equipment he’ll use on your job — no bait-and-switch with subcontractors. He walks your system, checks filter condition, notes vent configurations, and runs a video borescope through representative duct sections to show you what’s actually in there and tailor the cleaning approach.
- 2
Protect your home and contain the work zone. We lay protective flooring, seal off the work area from living spaces, and set up our Nikro negative-air collection unit at the plenum. This HEPA-filtered machine maintains continuous suction during cleaning so dislodged debris is captured at the source, not redistributed through your home.
- 3
Mechanical agitation with contact cleaning tools. The Rotobrush system sends a spinning brush head through each branch line, physically contacting and dislodging buildup from duct walls. In San Antonio’s older homes with rigid metal ductwork, we may switch to pneumatic whipping tools that navigate elbows and transitions more effectively — Richard Anderson makes this call based on what the inspection revealed.
- 4
Register, boot, and component hand-cleaning. While the mechanical tools work the main lines, we remove and hand-clean every vent cover, vacuum the boot cavity behind it, and treat any mold or mildew with Guardsman antimicrobial where indicated. These detail steps separate a thorough cleaning from a rushed “blow-and-go” job.
- 5
Post-cleaning verification and system reset. We run a second video pass to document results, replace any access panels we opened, install a fresh filter if you’ve provided one, and restart your system to confirm normal operation. Richard Anderson reviews the before-and-after footage with you, explains anything notable he observed, and leaves you with documentation of the work performed.
How Much Does Air Duct Cleaning Cost in San Antonio?
A typical residential full system cleaning in San Antonio runs $450 to $850 depending on home size, duct configuration, and last service date. Smaller homes with straightforward flex-duct systems in neighborhoods like Converse or Live Oak often fall at the lower end, while larger homes in Timberwood Park with extensive hard-pipe duct networks, multiple HVAC zones, or significant buildup from 10+ years of neglect may reach the upper range. Commercial duct cleaning starts around $1,200 and scales with system complexity and square footage.
Several factors affect your specific price: the number of supply and return vents (we count each one), whether your ductwork is accessible or buried in San Antonio’s common slab-on-grade construction with attic-mounted air handlers, and whether video inspection reveals damage requiring repair before cleaning proceeds. Add-on services like dryer vent cleaning ($150 to $250) or full HVAC cabinet cleaning ($200 to $350) can be bundled for efficiency if we’re already on site.
To avoid overpaying, get an in-person estimate that specifies vent count and scope — phone quotes based on square footage alone often balloon on arrival. Our estimates are free, detailed, and fixed once accepted. We’ll show you the video inspection results, explain exactly what your system needs, and let you decide without pressure. Call (866) 769-1699 to schedule yours.

Frequently Asked Questions — Air Duct Cleaning in San Antonio
Air duct cleaning is the mechanical removal of accumulated dust, debris, allergens, and microbial growth from the interior surfaces of your HVAC ductwork and connected components. We physically dislodge and extract this material using brush systems and negative-air collection — not just blow it around — so it leaves your home entirely rather than resettling. In San Antonio’s climate, we commonly remove fine caliche dust, pollen loads from live oak and mountain cedar, pet dander, construction debris, and the organic film that supports mold growth in humid duct sections.
A typical residential full system cleaning takes 3 to 5 hours for a single HVAC system in a San Antonio home. Larger homes, multiple zones, or systems with significant buildup and accessibility challenges may extend to 6 hours. We schedule realistic time windows and don’t rush — the 17 years of experience behind each job means we know where the hidden accumulation lives and take the time to address it properly.
Residential air duct cleaning in San Antonio typically ranges from $450 to $850 for a complete full-system service, with smaller homes or partial cleanings sometimes falling below that range and complex commercial jobs running higher. Your exact quote depends on vent count, duct type, accessibility, and condition — which is why we provide free in-person estimates rather than guess over the phone. Call (866) 769-1699 for an exact quote; estimates are free and carry no obligation.
