Air Duct Cleaning Cost - One Price Per System, Agreed Before We Start

How Much Does Air Duct Cleaning Cost in San Antonio?

Air Duct Cleaning in San Antonio typically costs $285 to $485 for a standard single-system home of roughly 1,500 to 2,500 square feet in 2026. Most families in neighborhoods like Alamo Heights, Stone Oak, and Helotes pay right around $350 for a full-system cleaning that includes all supply and return ducts, the main trunk lines, and the air handler. A smaller condo or apartment near the Pearl or Southtown usually falls in the $200 to $275 range, while larger two-story homes in Dominion or Shavano Park with two HVAC systems run $550 to $800. Every quote from Morton’s Air Duct Cleaning comes as a written price before we start, so the number you approve is the number you pay.

Air Duct Cleaning Cost Breakdown (2026)

Here’s what a typical air duct cleaning invoice looks like in San Antonio this year. Prices are for a standard single-family home with one HVAC system and 8 to 14 vents.

Service Item	Typical Cost Range (San Antonio, 2026)
Whole-home air duct cleaning (one system)	$285 to $485
Per additional return or supply vent	$10 to $18 each
Air handler / blower cleaning	$60 to $120
Dryer vent cleaning (add-on)	$75 to $125
Furnace or coil cleaning (if heavily soiled)	$80 to $160
Sanitizing fog treatment (optional)	$90 to $160
Whole-home ductwork replacement (rare)	$1,800 to $4,500

These San Antonio numbers match what we see week to week on jobs across the north side, from Castle Hills to Timberwood Park. Prices here run slightly below Austin and Dallas because the local HVAC market is competitive. What moves the price most is the number of vents, whether you have one system or two, and how long it’s been since the last cleaning. Homes with pets usually need a bit more time on the return side, where hair builds up fastest.

At Morton’s Air Duct Cleaning, we write the price before we open a single register. No “$49 whole house” bait, no surprise add-ons at the door. If you call (903) 354-8393, we’ll give you a straight answer about what your home needs and what it will cost.

What Affects Air Duct Cleaning Pricing in San Antonio

A few local factors consistently shift Commercial Duct Cleaning and residential air duct cleaning prices here. If you live in San Antonio, these are the ones that matter most for your quote.

• Number of HVAC systems and vents. A two-story home in Stone Oak or a ranch house with an addition in Oak Hills often has two separate systems. That doubles the work, but not usually the full price. Figure roughly 60 to 80 percent more for the second system.
• Pets in the home. We love the dogs in Alamo Heights and the cats in Monte Vista, but pet dander and fur load up the returns faster than anything else. Homes with two or more shedding pets often need additional agitation time on return ducts and may push a $300 quote closer to $400.
• Age of the home and duct condition. Older homes in areas like Jefferson, Woodlawn Lake, and Olmos Park often have rigid metal ducts with fiberglass-lined interiors from the 1950s through 1970s. These require gentler cleaning methods and sometimes more time. Flexible ducts in newer subdivisions like Alamo Ranch or Cibolo Canyons clean faster and usually cost less.
• Level of contamination. If the previous owners smoked, did drywall work with the system running, or if a bathroom fan was vented into the return plenum (we see this more than you’d expect in San Antonio’s 1980s builds), the buildup takes longer to remove. We’ll tell you what we see before we start, so there are no mid-job surprises.
• Access to the air handler. Attic-mounted systems in Texas heat make the job longer during summer months. Attics in San Antonio routinely hit 130 degrees from June through September, which is legitimate hard work. Our techs earn every dollar up there. Ground-floor closets and garage-mounted handlers are faster and sometimes modestly cheaper.
• Add-on services. Dryer vent cleaning is the most common add-on. San Antonio’s combination of hard water minerals and high summer humidity also leads some families to request a sanitizing fog treatment for musty-smelling ducts, particularly after the rainy season.

Every Morton’s technician arrives with professional equipment from Rotobrush and Nikro, which lets us clean thoroughly without ripping into walls or dragging rental-grade gear through your living room. Shoe covers go on at the door, drop cloths go down over floors and furniture, and we work around nap schedules and pets where we can. Our tools are quieter than most because we know there’s often a toddler asleep down the hall in the middle of a Tuesday afternoon.

How to Save on Air Duct Cleaning

The best way to keep the price down in San Antonio is to not wait until the ducts are visibly dirty. A system that gets cleaned every 3 to 5 years needs less time per visit than one that hasn’t been touched since the Clinton administration. Here’s what actually helps:

• Change your filters on schedule. In San Antonio’s pollen-heavy spring and dusty summer, a 1-inch filter should be changed every 30 to 60 days. Better filtration means less buildup downstream, which can mean a faster, lower-cost cleaning.
• Bundle dryer vent cleaning with air duct cleaning. If you’re already paying for the visit and the tech is on site, adding dryer vent service usually costs $75 to $125. A standalone dryer vent call trip can run $150 or more on its own. It’s simple math.
• Have both systems done at once. If you’ve got two units in a large home, scheduling both during the same visit avoids a second dispatch fee and saves you 10 to 20 percent versus two separate appointments.
• Get your quote before you commit. Morton’s writes the price down before any work starts. That alone prevents the most common way people overspend on duct cleaning: getting quoted one number on the phone and a different one at the door.
• Ask what’s included. Some San Antonio companies quote a low base price and then charge separately for the air handler, the return plenum, or the trunk line. Our quote covers the complete system, from the returns to the supply registers. If a quote sounds too cheap to be real, it probably is.

Call (903) 354-8393 for a free estimate. We’ll go over what’s included line by line, and the price we quote is the price on your invoice.

Is Air Duct Cleaning Worth the Cost in San Antonio?

For most San Antonio families, yes. The city’s climate means your HVAC system runs 7 to 9 months of the year, and during a normal spring, cedar and oak pollen blow through every open window and door. That pollen, plus construction dust from the constant growth on the 1604 corridor, settles in ductwork and recirculates through the house. A clean system moves air more efficiently, which matters on a 100-degree August day when your AC is fighting for every degree.

Here’s what we hear from customers after a cleaning in places like Terrell Hills and Boerne: the house smells neutral again, dusting intervals stretch from weekly to every other week, and the return register stops turning gray around the edges. For a full air duct cleaning in San Antonio, the cost lands between $285 and $485 for most homes, which puts it in the same ballpark as a routine AC tune-up but with benefits you notice throughout the living spaces, not just at the thermostat.

We don’t do scare tactics. Your ducts are not a health emergency. But if it’s been more than five years or you’ve just finished a home renovation, having the system professionally cleaned is a reasonable, sensible expense. And if we miss something, our 365-Day Done Right Promise means we return and make it right. No arguments, no fine print.

What’s Included in a Morton’s Air Duct Cleaning Visit?

Every air duct cleaning with Morton’s Air Duct Cleaning follows the same careful sequence, and every step is included in the written price you approve before we start. Here’s what happens when we arrive at your San Antonio home.

1. Walkthrough and written quote

The technician walks the home with you, counts the vents, locates the air handler, and checks the return side. Then you get a written price. If the number doesn’t work for you, we leave and there’s no charge. That’s the whole policy. No pressure, no awkward standing around while you decide.

2. Floor and furniture protection

Drop cloths go down in every room we work in. Shoe covers go on at the door and stay on. This is part of the Cedarwell Care Promise, which every Morton’s technician works to. If you’ve got a dog crate in the living room or a baby gate across the hall, we work around them, not over them.

3. System cleaning

We connect a HEPA-filtered negative air machine from Abatement Technologies or Nikro to the ductwork, which puts the system under negative pressure so dust and debris get pulled out rather than blown into the house. Then we agitate the ducts with rotating brushes from Rotobrush, cleaning each return, supply line, and trunk. The air handler gets brushed and vacuumed too, because a clean duct system attached to a dirty blower wheel is half a job.

4. Photo of the clean-up

Before we pack up, we take a photo of the finished work and the protected floors, so you can see the house was left the way we found it. The photo is part of the job, not a favor. If we used drop cloths and shoe covers, you’ll see them in the picture. If we didn’t, you’ll know, and the 365-Day Done Right Promise means we’ll fix it.

Air Duct Cleaning vs. Dryer Vent Cleaning: What Do You Actually Need?

These two services get confused in San Antonio all the time, and for good reason. They both involve cleaning ducts and they both matter for a well-maintained home. But they are different services with different prices and different frequencies.

Air duct cleaning covers the HVAC system: the return ducts that pull air in, the supply ducts that push conditioned air out, the trunk lines, and the air handler. It’s typically done every 3 to 5 years, and it costs $285 to $485 for a standard San Antonio home. Signs you need it include visible dust around registers, a persistent musty or stale smell that doesn’t go away with filter changes, and excessive dust settling on furniture within days of cleaning.

Dryer vent cleaning clears the duct that runs from your dryer to the outside. Lint builds up in that line, and in San Antonio’s dry winter months, a clogged dryer vent is a fire risk. This service costs $75 to $125 as an add-on and should be done every year for most families. Signs you need it include clothes taking longer than one cycle to dry, a dryer that runs hot to the touch, or lint visible around the outside vent hood.

If you do both at once, you get the best price on the dryer vent side since the tech is already at your home with equipment set up. It’s the most common combination we see in San Antonio, especially among families who do an annual dryer vent cleaning and bundle a duct cleaning when it’s due.

Red Flags to Watch for with San Antonio Duct Cleaning Companies

The duct cleaning industry has its share of operators who advertise an impossibly low price and then upsell once they’re inside. Here’s what to watch for when you’re comparing quotes in San Antonio.

• Phone quotes that refuse to commit. If a company won’t give you a range over the phone or insists on seeing the home but still won’t put a number in writing once they’re there, walk away. A written price before work starts is the single best protection against overpaying.
• Extra charges for standard items. The air handler, the return plenum, and the trunk line are not “upgrades.” They’re part of the duct system. A company charging separately for these is inflating the price with things that should be included.
• Blower door or “free inspection” bait. Some outfits offer a low-cost inspection and then find a $900 problem in every home. We’ll tell you what we see and what it costs, and if you don’t want the work, you’ll know exactly what was recommended and why.
• No shoe covers, no drop cloths. If a company doesn’t mention floor protection before the job, assume your floors are on their own. At Morton’s, shoe covers and drop cloths are non-negotiable on every visit. Every single one.

How Much Does Air Duct Cleaning Cost by Neighborhood in San Antonio?

San Antonio’s neighborhoods vary widely in home age and architecture, which means pricing varies too. Here’s a realistic look at what we charge across different parts of the city, based on years of service calls.

• Alamo Heights and Terrell Hills: Mix of 1920s to 1970s homes with mature trees and sometimes older sheet metal ducts. Expect $300 to $500 depending on vent count and duct condition.
• Stone Oak and Timberwood Park: Larger 1990s and 2000s homes, many with two systems. Figure $480 to $700 for a full two-system clean.
• Helotes and Grey Forest: A range of sizes and ages, plus more pets per household on average. Most jobs land between $300 and $450.
• The Pearl, Southtown, and downtown condos: Smaller square footage, fewer vents, quick access to the air handler. Typically $200 to $300.
• Leon Valley and Balcones Heights: Mid-century homes with accessible systems and moderate vent counts. Usually $275 to $400.
• Alamo Ranch and the far west side: Newer builds with flexible ducts that clean efficiently. Most homes come in at $250 to $380 for a single system.

These are real numbers from real jobs, not generic national averages. San Antonio’s HVAC market has its own rhythm, and we know it because we’ve been cleaning ducts here since 2005. When you call (903) 354-8393, the estimate you get reflects your actual home, not a spreadsheet from a franchise in Ohio.

FAQs: Air Duct Cleaning Cost

How much does air duct cleaning cost in San Antonio in 2026?

Most single-system homes in San Antonio cost $285 to $485 for a complete air duct cleaning in 2026. Smaller homes and condos run $200 to $275, while larger two-system homes can reach $550 to $800. Morton’s provides a written quote before any work begins, so the number you approve is the final number. Call (903) 354-8393 for a free estimate on your specific home.

Is it cheaper to clean air ducts or replace ductwork?

Cleaning is dramatically cheaper. A full air duct cleaning runs $285 to $485 in San Antonio, while replacing ductwork typically costs $1,800 to $4,500 or more. Replacement only makes sense for ducts that are collapsed, torn, or contaminated beyond what cleaning can address. In most homes, a professional cleaning restores the system for under a tenth of replacement cost.

Can you clean air ducts the same day I call?

Often, yes. Morton’s keeps San Antonio scheduling flexible and can frequently accommodate same-day or next-day appointments, especially for smaller homes. Call (903) 354-8393 and a live person will tell you exactly what’s available. A real human answers the phone 24/7, not a voicemail tree.

How often should air ducts be cleaned in San Antonio?

For most San Antonio homes, every 3 to 5 years is the right interval. Homes with multiple pets, allergy-sensitive family members, recent renovations, or smokers should lean toward every 2 to 3 years. The city’s heavy oak and cedar pollen seasons mean ducts here collect more debris than homes in many other parts of Texas. If your home has gone more than five years without a cleaning, it’s worth scheduling an inspection.

What does Morton’s air duct cleaning include for the price?

Every Morton’s cleaning includes all supply and return ducts, trunk lines, the air handler, floor protection with drop cloths, shoe covers on every technician, professional equipment from Rotobrush and Nikro, a written price before work starts, and a photo of the clean-up before we leave. The entire job is backed by the 365-Day Done Right Promise. If it’s not right, we make it right. No exceptions.

How much does dryer vent cleaning cost as an add-on in San Antonio?

Adding dryer vent cleaning to an air duct cleaning costs $75 to $125 in San Antonio. It’s the lowest-cost way to protect your home from a lint fire and to cut drying times. Bundling both services in one visit saves you money compared to separate appointments, since the technician and equipment are already on site.

Does air duct cleaning help with allergies?

Many San Antonio families report fewer allergy symptoms after a professional cleaning, especially those sensitive to oak, cedar, and mold spores. A clean system removes accumulated pollen, dust, and pet dander that recirculates every time the AC runs. It’s not a cure, but it does reduce the load of allergens moving through your living spaces. If allergies are your main concern, mention it when you call (903) 354-8393 and we’ll discuss whether a sanitizing fog treatment makes sense for your home.

Is Morton’s air duct cleaning worth the price?

We think so, and the 365-Day Done Right Promise backs that up. Since 2005, Morton’s has cleaned ducts in San Antonio homes from Alamo Heights to Alamo Ranch, with a written price before every job, shoe covers and drop cloths on every visit, and professional equipment from brands like Honeywell, Aprilaire, and Guardsman.

Why San Antonio Families Choose Morton’s for Air Duct Cleaning

Not every duct cleaning company in San Antonio works the same way. Here’s what Morton’s does differently, in plain terms.

• We tell you the price in writing before we start. Not an estimate range, not a “we’ll see.” A number. It’s the number you pay.
• We protect your floors and furniture as a matter of policy. Drop cloths and shoe covers on every visit. The Cedarwell Care Promise requires it, and so does common courtesy.
• We bring professional-grade equipment. Rotobrush agitation tools, Nikro HEPA filtration, Abatement Technologies negative air machines. This is not rental gear from a home improvement store.
• We leave you with proof. A photo of the clean-up before the crew pulls out of the driveway. You’ll see the floors we protected and the work we did.
• We answer the phone. 24/7, a live person picks up. Not a call center, not a chatbot. A real human who works for Morton’s.
• We stand behind the work for a full year. The 365-Day Done Right Promise means if it’s not right, we make it right, full stop. That promise applies to every San Antonio job we do.
