Air duct cleaning pricing in San Antonio is one of the most misunderstood topics in the home services industry — and unfortunately, one of the most exploited. A simple Google search turns up ads promising whole-house duct cleaning for $49 or $79. These offers exist for one reason: to get a technician through your door, manufacture a list of necessary 'upgrades,' and extract $400–$800 from homeowners who started expecting a $49 service.
This guide gives you honest, transparent pricing information based on our decade of experience serving San Antonio homeowners. We want you to be an informed buyer — whether you hire us or someone else.
The bottom line: professional air duct cleaning for a typical San Antonio home (1,500–2,500 sq ft, one HVAC system) costs between $199 and $349 from a legitimate provider using proper equipment. If someone quotes you less than $150 to clean your entire duct system, ask detailed questions about exactly what's included — and be prepared for the upsell.
Flat-Rate, Written Estimates
We provide a flat-rate quote in writing before we start. What we quote is what you pay — no add-ons, no bait-and-switch.
Honest Inspection First
We inspect your system before quoting. If cleaning isn't genuinely needed, we'll tell you — and not charge for the inspection.
Licensed & certified
Our pricing reflects professional-grade equipment, certified technicians, and a service that actually works.
What Does Air Duct Cleaning Cost in San Antonio? — The Real Numbers
Small Homes (under 1,500 sq ft) — $149–$229
Smaller homes with one HVAC system and 8–12 vents typically fall at the lower end of our range. These jobs can often be completed in 2 hours using standard truck-mounted equipment.
Average Homes (1,500–2,500 sq ft) — $229–$349
The most common San Antonio home size. One or two systems, 12–20 vents. Typical completion time 2.5–4 hours. This is the baseline for most of our residential appointments.
Larger Homes (2,500–4,000 sq ft) — $299–$449
Larger duct systems require more time, additional equipment repositioning, and may involve multiple air handlers. Homes with zoning systems or older ductwork may also fall in this range.
Estate Homes (4,000+ sq ft) — $399–$599+
Multi-system homes, large square footage, and complex duct configurations are quoted individually. We provide free estimates for all large residential and estate properties.
These are baseline prices for standard cleaning. Add-on services (sanitizing, mold treatment, dryer vent cleaning, coil cleaning) are priced separately and quoted upfront.

What's Included in a Professional Duct Cleaning?
A legitimate air duct cleaning service includes all of the following — if a provider is skipping steps, the price will be lower but the service won't be effective:
- Full visual inspection of supply ducts, return ducts, and air handler
- Truck-mounted HEPA vacuum connected to main return plenum — creates negative pressure throughout the system
- Rotary brush agitation: mechanical cleaning of all accessible duct runs
- All supply registers and return covers cleaned (brushed, vacuumed, reinstalled)
- Boot openings vacuumed (the metal connection point between duct and register)
- Air handler cabinet inspection (for visible mold or debris)
- Final walk-through: technician shows you what was removed and answers questions
- Written receipt documenting work performed
The Bait-and-Switch Problem in San Antonio Duct Cleaning
The Federal Trade Commission has specifically warned consumers about deceptive duct cleaning advertising. Here's how the scam typically works in San Antonio:
The Low-Price Ad
A company advertises duct cleaning for $49–$79. The ad may say 'whole house' or '10 vents.' The technician arrives with a portable shop vac and a brush.
The Manufactured Problem
During the visit, the tech says they've found mold, heavy contamination, a 'failed air handler,' or that your ducts are 'beyond standard cleaning.' An estimate of $400–$800 in additional services is presented.
The Pressure Close
You're told the additional services are urgently needed for health and safety. Photos of generic dirt may be presented as 'your ducts.' Some companies have hidden cameras show 'mold' that is simply dust or discoloration.
Protection: get multiple written estimates, ask specifically what equipment will be used (look for 'truck-mounted HEPA vacuum'), and check BBB and Google reviews before booking. We are BBB Accredited and have 200+ verified Google reviews — our reputation is our business.

Optional Add-On Services and Their Costs
These are legitimate services that some homes genuinely benefit from — but they should always be quoted separately upfront, not sprung on you during a visit:
- Duct Sanitizing (EPA-registered antimicrobial treatment) — $75–$150 add-on
- Mold Treatment (for confirmed mold presence) — $150–$350 depending on extent
- Dryer Vent Cleaning — $89–$149 standalone or bundled discount
- Condenser Coil Cleaning (outdoor unit) — $99–$179
- Evaporator Coil Cleaning (indoor air handler) — $149–$299
- Air Duct Sealing (Aeroseal or manual sealing) — quoted separately by job
Every add-on service we recommend is based on something we actually observe during inspection. We document our findings in writing and let you decide — no pressure.
San Antonio Neighborhoods We Serve
From the cedar-lined hills of the Northwest Side to the historic bungalows of the inner loop, every San Antonio neighborhood has its own air-quality challenges. Our crews work across all of Bexar County and know the common duct, HVAC, and airflow issues for each area — so you get service tuned to your home, not a one-size-fits-all visit.
Stone Oak & Far North
78258 · 78260 · 78261
Larger two-story homes with multi-zone HVAC. Long duct runs between floors trap dust; we clean each zone separately so airflow stays balanced.
Alamo Ranch
78253
One of San Antonio's fastest-growing master-planned communities. New construction leaves drywall dust and debris in ducts — a post-build cleanout is common here.
Helotes & Northwest
78023 · 78250
Deep in Texas cedar country. Mountain cedar pollen loads ducts every winter; cleaning before and after cedar season eases allergy symptoms.
Alamo Heights & Terrell Hills
78209
Historic 1920s–1940s homes often still run on original ductwork prone to leaks, debris, and outdated flex duct that benefits from inspection and sealing.
Leon Valley
78238
Established northwest neighborhoods with aging duct systems. Older insulation inside ducts can degrade — we inspect before recommending replacement.
Shavano Park
78231
Large estates and multi-zone HVAC systems. Longer duct runs and larger homes need thorough, zone-by-zone cleaning to reach every register.
Southside & Southtown
78221 · 78211 · 78214
Older South Side homes with decades of accumulated dust. Historic bungalows near Mission Reach often have undersized or modified ductwork.
Medical Center & North Central
78229 · 78240
Dense multi-family, townhomes, and medical-area apartments. Shared and compact duct systems need careful cleaning to avoid cross-contamination.
Converse · Schertz · Universal City
78109 · 78154 · 78148
Northeast Bexar near JBSA Randolph and Fort Sam. Military families move often, so ducts rarely get cleaned between occupants — we make it easy.
Downtown · King William · Lavaca
78205 · 78204 · 78210
Historic loft conversions and older commercial ductwork. Renovated properties often inherit decades of debris in original duct runs.
Windcrest & Castle Hills
78239 · 78218
Mid-century established neighborhoods with aging duct insulation and settled dust — a full system inspection usually reveals real cleanup opportunities.
Southeast · Kirby · China Grove
78219 · 78263
Growing southeast corridor with a mix of new builds and older ranch homes. Post-renovation and post-construction duct cleanouts are frequent requests.
