Air Duct Cleaning Cost Breakdown (2026)
Here’s how a typical Air Duct Cleaning Near Me in San Antonio, TX invoice breaks down this year. These are real-dollar ranges our technicians see across the metro area, from Alamo Heights to Helotes to Converse:
| Service Item | Typical Range (San Antonio, 2026) |
|---|---|
| Full-system air duct cleaning (up to 10 vents) | $300 – $450 |
| Each additional vent beyond 10 | $25 – $40 per vent |
| Full-system cleaning for homes 2,500 – 3,500 sq ft (12 – 20 vents) | $450 – $700 |
| Large homes 3,500+ sq ft or two-story systems with dual zones | $700 – $950 |
| Dryer vent cleaning (standalone) | $75 – $150 |
| Dryer vent cleaning (add-on with duct cleaning) | $50 – $100 |
| Sanitizing / antimicrobial fog treatment | $150 – $325 |
| Return-side deep cleaning or coil cleaning (where accessible) | $100 – $250 |
A note on those numbers: they reflect what we’re quoting for San Antonio homes in 2026, not national averages that get recycled on every other website. Local conditions matter here. San Antonio’s limestone-rich soil produces fine white dust that finds its way into return ducts faster than in other Texas markets. Our spring “cedar fever” season drives pollen levels that make duct cleaning a mid-year priority for allergy households. And if you live in an older neighborhood like Jefferson, Woodlawn Lake, or Highland Park with original 1950s-1970s ductwork, expect a bit more labor if ducts need extra attention due to age, collapsed sections, or animal entry.
What drives the price up or down?
Two homes on the same street can get different quotes because of what’s inside the ducts, not the square footage. Access points that are tight or awkward in San Antonio’s older pier-and-beam homes add labor time. A system with a single return and 10 supply vents is straightforward. A two-story home in Stone Oak with dual zones, 18 vents, and two returns takes longer. The condition of the ducts themselves matters too – if flex duct has been crushed in a hot attic, cleaning takes more care and sometimes a repair conversation.
What Affects Air Duct Cleaning Pricing in San Antonio
- Square footage and vent count. More conditioned space means more linear feet of ductwork and more supply registers. A 1,400-square-foot home in Dignowity Hill with 8 vents is a far faster job than a 3,200-square-foot home in Sonterra with 20 vents.
- Age and condition of the duct system. San Antonio’s housing stock spans a wide range – from 1930s bungalows near downtown with metal ducts that have decades of buildup, to new construction in far-west neighborhoods like Alamo Ranch with flex duct that often contains drywall dust and construction debris from day one.
- Pet load and occupant count. Three dogs and two cats shed more than a single goldfish. Homes in Terrell Hills and Olmos Park with multiple large-breed dogs tend to accumulate dander and fur in returns faster than the regional average, which can mean a second pass during cleaning and a higher final quote.
- Allergen levels and local climate. San Antonio’s high spring pollen counts from mountain cedar and live oak, combined with humid summers that keep dust sticky inside ducts, mean filters clog faster and ducts accumulate more biological material than in drier climates like El Paso or Lubbock. If household members have documented allergies, the sanitizing treatment becomes a more common recommendation.
- Access and attic configuration. Many San Antonio attics are unconditioned and hit 140°F in July. A technician working in that heat moves slower for safety reasons. Tight crawlspaces, finished-basement conversions, or AC closets in older homes add time to the job.
- Add-ons: dryer vent, sanitizing, coil cleaning. Each add-on carries its own line item. A bundled job (ducts + dryer vent + sanitizing) in a 2,000-square-foot home often lands around $600 – $800 total, which is more cost-effective than booking each service separately over time.
Every estimate Paul Adeyemi signs includes the same assurance: a written price laid out line by line before the crew lifts a tool. No “Oh, we found something extra” surprises at the end. What we quote is what you pay.
Is Air Duct Cleaning Worth the Cost in San Antonio?
If you’re asking whether the investment pays off, you’re asking the right question. Here’s what we tell customers honestly: air duct cleaning is not a mandatory annual service like changing HVAC filters. It’s valuable when there’s a reason. Homes in San Antonio with pets that shed heavily, kids with allergies, smokers in the household, or recent renovations see the most obvious benefit. So do homes where the previous owners had pets and you’ve never been in the ducts to know.
The cost of cleaning is a fraction of the cost of HVAC system strain. When coils and blower motors work against a blanket of dust and pet hair, they run longer and hotter. A $450 duct cleaning is cheaper than a $1,800 blower motor replacement. San Antonio summers put hard demand on AC systems from May through October – the cleaner the airflow path, the less work the system does to move the same volume of air.
We use Rotobrush and Nikro equipment on every job. These aren’t entry-level rental machines. Rotobrush’s agitation systems break loose caked material on duct walls that simple vacuum attachments leave behind. Nikro HEPA-filtered vacuums capture the dislodged particles instead of blowing them into your living room. For homes where air quality is a top concern, we also offer Honeywell media air cleaner recommendations and Aprilaire filtration guidance based on what we see in your ducts. These are the same brands San Antonio HVAC wholesalers stock for professional contractors, not consumer-grade equipment from a big-box store.
A practical tip from our team in the field: take a photo of your supply register before cleaning and another one after. The visual difference in the register and the visible portion of the duct is usually stark. We also take a photo of the clean-up before the crew leaves, so you can see for yourself that floors and furniture were protected the entire time.

How to Save on Air Duct Cleaning
Not everyone needs the full package with every add-on from our Commercial Duct Cleaning services. Here’s how to get the clean you need without paying for extras you don’t:
- Know your vent count before you call. Count your supply registers (the vents that blow air) and your returns (the larger grilles that pull air back). Report this number accurately when requesting a quote. It prevents surprises and lets you compare apples to apples between companies.
- Bundle dryer vent cleaning with the duct job. Duct cleaning plus dryer vent cleaning together usually saves $25 – $50 versus booking them separately. Dryer vent cleaning matters more than most people realize – lint accumulation is the leading cause of dryer fires, and San Antonio’s dusty environment fills dryer vents quickly.
- Change your HVAC filter after, not before, the cleaning. A fresh filter after cleaning extends the clean period. But many homeowners replace the filter two weeks before a cleaning, waste money, and then run a dirty filter post-clean. Buy your replacement filter, keep it in the wrapper, and install it the day your technician leaves.
- Ask about what’s included in the base price. At Morton’s, the base price includes shoe covers and drop cloths on every visit, no extra charge. Some companies charge a “floor protection fee” as a line item. We don’t. A written price before any work starts means you can compare what’s actually included.
- Don’t automatically pay for sanitizing. The sanitizing or antimicrobial fog treatment is valuable in homes with visible mold, persistent musty odor, or severe allergy symptoms. If none of those conditions exist, skip it – or ask your technician to show you what they’re seeing in the ducts before deciding. Our technicians will happily show you the camera view.
- Schedule during our slower seasons. Summer and early winter are our busiest periods in San Antonio – June through August for obvious AC-related reasons, and December when holiday guests are coming. Late spring (May) and late fall (October) often have more scheduling flexibility and occasional promotions.
For a firm number on your specific home, call (903) 354-8393. Estimates are free, a live person answers 24/7, and Paul Adeyemi and the team will give you a written price before anyone touches a register.
What to Expect From a Professional Air Duct Cleaning
Knowing what happens during the job helps you understand what you’re paying for. A proper air duct cleaning in San Antonio takes 2 to 5 hours depending on home size, vent count, and system complexity. Here’s the sequence when our crew arrives:
- Protection first. Shoe covers go on at the door. Drop cloths go down under the work path, including the areas around your registers and returns. Pets get a wide berth; our technicians work around them without disturbing nap schedules any more than necessary.
- System inspection. We check the furnace or air handler, the return plenum, and a sample of supply runs. We’re looking for animal entry, moisture, mold indicators, crushed flex duct, and general buildup level. This informs whether the job goes as quoted.
- Negative pressure setup. A HEPA-filtered vacuum creates negative pressure in the duct system, so anything we knock loose gets pulled toward the vacuum, not pushed into your living space. This is the single biggest quality difference between professional cleaning and a “blower door with a brush” half-job.
- Mechanical agitation. Using Rotobrush tools, we scrub the interior walls of the ducts to dislodge accumulated dust, pet dander, construction debris, and that fine San Antonio limestone dust. Abatement Technologies equipment is deployed where air scrubbers are needed for especially dusty post-renovation homes.
- Vent-by-vent cleaning. Each supply register is removed, cleaned, and reinstalled. The same happens with returns. If you have a particularly crusty bathroom vent or a kitchen register caked with grease vapor and dust, expect extra attention there.
- Final walkthrough and photo. We walk you through what we did, show you the debris we collected, and take a photo of the clean-up area before the crew leaves. Your floors should look exactly as they did when we arrived – minus the duct dust.
The Guardsman brand we carry for antimicrobial treatments is the same product line hospitals and commercial buildings use. It’s not a fragrance spray; it’s a residual antimicrobial applied to sanitized duct surfaces. The choice is always yours, and the recommendation only comes if what we see during inspection justifies it.
What Affects Air Duct Cleaning Pricing in San Antonio
San Antonio is a big, sprawling metro with wildly different housing stock and environmental conditions. The same company quoting the same house in different parts of town won’t change the price because of the ZIP code, but the conditions that come with those ZIP codes absolutely affect the work:
Seasonal pollen and dust load
The San Antonio pollen calendar peaks twice: mountain cedar from late December through February, and oak pollen from March through May. During these windows, HVAC systems pull massive amounts of pollen through return ducts, especially in homes where windows are opened at night during the brief cooler periods. Homes with pets that go in and out bring that pollen back on fur. A May duct cleaning in Alamo Heights often reveals pollen and dander levels that surprise even us.
Humidity and biological growth
San Antonio’s summer dew points in the mid-70s mean condensation sits longer on coil surfaces and inside poorly insulated ducts, especially in attics. That moisture provides a growth surface for mold and mildew. If your home has a history of AC condensation overflow or humid indoor air, the duct surfaces may carry more biological material than a typical dry-climate home. This affects whether sanitizing is recommended and how much agitation the Rotobrush equipment needs to do.
Construction debris in newer neighborhoods
In newer developments south of Loop 1604, including areas near Palo Alto College and Texas A&M-San Antonio, and the explosive growth corridors around Culebra Road and Potranco Road, drywall dust and sawdust frequently remain in duct systems from initial construction. Builders don’t generally clean ducts before handoff, and that fine dust circulates for years if never addressed. Homes built within the last 3 to 5 years in these areas often need a thorough initial cleaning that takes longer than an equivalent older home.
Old ductwork in historic neighborhoods
Homes in Monte Vista, Lavaca, King William, and Alta Vista sometimes have original metal ductwork that’s 60 to 80 years old. That ducting is often in surprisingly good shape, but accumulated material over those decades requires more passes. In some cases, joints have separated or rusted, which means some air has been escaping into the crawlspace or attic. We’ll flag that during inspection and give you a straight assessment of whether cleaning is still worthwhile or whether repair work should happen first.
Air Duct Cleaning vs. Replacement Cost in San Antonio
A question we hear regularly from homeowners in San Antonio: “Should I clean or just replace the ducts?” The answer lives in the condition of what’s there. Here’s the straight math:
- Cleaning cost: $350 – $700 for a typical home
- Partial duct repair (patching holes, resealing joints): $150 – $500
- Full duct replacement: $3,000 – $8,000 depending on home size, duct type, accessibility, and whether the system is metal or flex
Unless your ducts are collapsed, rusted through, filled with vermiculite or asbestos (which requires abatement, not cleaning), or severed by animals, cleaning is almost always the right first step. Replacement makes sense when the physical integrity of the ducting is compromised – not because it’s dirty. Cleaning can’t fix a crushed flex duct in a hot San Antonio attic or reattach a return plenum that’s come loose.
Where we draw the line: if we see asbestos-wrapped ducts or vermiculite insulation in an older home near downtown or in the Northeast side neighborhoods bordering Fort Sam Houston, we stop and refer you to a licensed abatement specialist. That’s not a cleaning job. We don’t touch it, and we’ll tell you exactly why. That’s part of the Cedarwell Care Promise – we’ll never charge you for work you don’t need, and we’ll tell you when you need someone else.
FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost for a 2,000-square-foot home in San Antonio?
Expect to pay between $350 and $550 for a full-system air duct cleaning in a 2,000-square-foot San Antonio home with 10 to 14 vents. Homes with multiple pets, heavy pollen buildup from cedar or oak season, or ducts that haven’t been cleaned in over a decade may fall at or slightly above the top of that range. Call (903) 354-8393 for a written quote on your specific home – the estimate is free, and you’ll know the exact number before we start.
Is it cheaper to clean air ducts or replace them?
Cleaning is dramatically cheaper. A full air duct cleaning in San Antonio runs $350 to $700, while full duct replacement typically costs $3,500 to $8,000 depending on home size and duct accessibility. Cleaning is the right choice when ducts are intact and simply dirty. Replacement only makes financial sense when ducts are collapsed, rusted through, severed by animals, or contaminated with hazardous material. A pre-cleaning inspection tells you which situation you’re in.
How often should air ducts be cleaned in San Antonio?
For most San Antonio homes, every 3 to 5 years is a reasonable interval. Homes with three or more shedding pets, a family member with significant allergies, a smoker in the household, or a recent renovation should consider cleaning every 2 to 3 years. San Antonio’s high spring pollen levels and dusty limestone soil put more load on HVAC systems than drier parts of Texas. New-construction homes on the outer loops often benefit from an initial cleaning within the first 12 months to remove construction dust.
Does air duct cleaning really help with allergies?
Yes, with a caveat: cleaning removes the accumulated pollen, pet dander, and dust that circulates through your HVAC system, but it can’t stop new material from entering. For allergy sufferers in San Antonio during mountain cedar and oak season, the combination of clean ducts, a fresh high-MERV filter, and an optional antimicrobial treatment makes a measurable difference. The ducts alone aren’t the whole story – but they’re a significant reservoir of allergens that recontaminates your air every time the system runs. Morton’s carries Honeywell and Aprilaire filtration products if you want a recommendation during your cleaning visit.
Can you clean air ducts the same day I call?
Often, yes. We hold same-day and next-day slots for San Antonio calls, and a live person answers the phone 24/7 – not an answering service, an actual human at our office. Peak summer and pre-holiday periods fill up faster, but even then, most customers get on the schedule within 48 hours. Call (903) 354-8393 and ask for current availability; we’ll give you a straight answer about when we can be there and what it will cost.
Why do air duct cleaning prices vary so much in San Antonio?
The range you see in San Antonio – roughly $299 to $900 for a full-system cleaning – comes down to equipment quality, what’s included in the base price, and how thorough the job actually is. Some companies run specials at $299 that cover only a limited number of vents or use consumer-grade shop vacuums. A proper NADCA-standard clean with Rotobrush or Nikro HEPA equipment, floor protection included, and written pricing upfront lands in the $350 to $700 range for most homes. If a quote is dramatically below market, ask what equipment they use and exactly what the price includes. A $299 “deal” that only cleans 6 vents and charges $49 per vent after that is not a deal.

Paul Adeyemi started Morton’s Air Duct Cleaning in San Antonio in 2005, and the pricing practice hasn’t changed since day one: written price before any work starts. Every time. No exceptions.

We’re an independently owned member of the Cedarwell family of companies. That means we answer to San Antonio homeowners, not to a corporate office in another state. The Cedarwell Care Promise governs every job: shoe covers and drop cloths on every visit, C.A.R.E. values that guide how our technicians treat your home, and a photo of the clean-up before the crew leaves. The 365-Day Done Right Promise backs everything: if it’s not done right, we make it right. That promise is stamped on every job, not offered as a consolation when something goes wrong.
Our technicians arrive in uniform, background-checked, and equipped with professional-grade tools from Rotobrush, Nikro, Honeywell, Aprilaire, Abatement Technologies, and Guardsman. This isn’t the equipment rack at the hardware store. It’s what commercial duct cleaners use, brought into your San Antonio home with care for the dog sleeping in the living room and the toddler napping down the hall. We work quietly where we can, protect floors and furniture as a matter of course, and leave your home looking like we were never there – except for the cleaner air.
