Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Air Duct Cleaning Across San Antonio
We’re the crew San Antonio families call when they want to know exactly what’ll happen in their house, what it’ll cost, and what their ducts actually look like before anyone leaves. Morton’s Air Duct Cleaning has been part of the Cedarwell family since 2005, and we dispatch to San Antonio from our Miami coordination office with crews who know the local housing stock - the 1950s-1980s tract homes in Harlandale and Edgewood, the older ranches in Mahncke Park, the limestone substrate that pushes every bit of ductwork into unconditioned attic space. You can reach us at (323) 918-4345 any time, day or night, and a live person will pick up. We don’t do alarm tactics or bait-and-switch pricing. We show up in uniform, put on shoe covers before we cross your threshold, and give you a written price before we touch a single register.
Why Morton’s Air Duct Cleaning Is San Antonio’s Preferred Air Duct Cleaning Company
San Antonio homeowners have plenty of options for Air Duct Cleaning, but they keep calling us back because we treat their house like it’s our own mother’s place. Paul Adeyemi built Morton’s on the idea that a technician should explain the work, show the problem, and name the price - every single time, no exceptions. Our crews carry the Cedarwell C.A.R.E. values into every home: drop cloths on your floors, quiet tool settings during nap hours, pet-safe product choices where we can use them. We’re not a national chain. We’re an independently owned Cedarwell company, and that matters when you’re deciding who gets access to your attic and your air.
Our 365-Day Done Right Promise isn’t a slogan we trot out when someone complains. It’s stamped on every job sheet. If something isn’t right, we make it right. Full stop. We also leave proof behind: a photo of the clean-up, taken before the crew walks out your door, so you can see your floors, your furniture, and your registers exactly as we found them - only cleaner. Calls come through to a live human 24 hours a day, not a voicemail maze, because we know duct questions don’t keep business hours.
Air Duct Cleaning Services in San Antonio
Air Duct Cleaning Services in San Antonio cover the complete removal of accumulated debris, pollen, and particulate from your supply and return ductwork, followed by sealing of accessible joints to prevent recontamination. A typical residential full-system clean in San Antonio runs $350-$650 for most homes under 3,500 square feet, with larger homes or systems with multiple HVAC units ranging $650-$950. Commercial duct cleaning starts around $800 and scales with system complexity. We don’t price per vent, and we don’t bait you with a coupon that doubles once we’re in your driveway. One flat price per system, agreed in writing, before we start.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back to the handler. In San Antonio’s climate, both sides collect debris, but returns near kitchens and pet areas load up fastest. We clean both with equal attention, using Rotobrush agitation and Nikro negative-pressure collection so nothing migrates into your living space during the job.

Video Inspection Before and After
Our techs run a camera down your trunk lines before we quote and after we finish. You see what we see. In San Antonio’s older homes, this step often reveals crushed flex runs, disconnected collars, or - in pre-1970s neighborhoods - asbestos-containing duct tape that changes how we approach the job entirely.

HVAC Duct Cleaning in San Antonio
HVAC Duct Cleaning in San Antonio means addressing the full air-handling ecosystem: the ducts, the plenum, the coils if accessible, and the return air pathways that feed your blower. Because San Antonio air conditioners run eight to ten months a year, your ductwork never gets a seasonal rest. A typical HVAC duct cleaning for a single-system home runs $400-$700, with two-system homes or properties with complex zoned layouts falling in the $700-$1,100 range. Every quote is written and signed before work begins.
Full System Source Removal
We don’t just vacuum registers. Our crews set up NADCA-standard negative pressure at the air handler, then use mechanical agitation to dislodge debris from duct walls without damaging aging flex liner. The debris is captured at the collection unit, not your carpet. This matters in San Antonio, where attic heat has already stressed your duct materials before we arrive.
Post-Clean Sealing and Testing
Cleaning without sealing is half a job in this market. We apply Guardsman mastic to accessible joints and reconnect any separated collars we find. In homes with Gulf moisture infiltration - common in older South Side and near West Side construction - sealing stops the condensation cycle that lets mold re-establish within a season.
Trusted Brands We Service in San Antonio
Our trucks carry professional-grade equipment from Nikro, Honeywell, and Aprilaire - brands we chose because they hold up to daily field use and because parts are available without long waits for San Antonio customers. We don’t rent entry-level gear by the hour. Our Rotobrush systems and Nikro HEPA collection units are maintained to manufacturer spec, and we stock common sealing and repair consumables so we’re not making a second trip to finish your job. When we find a component that needs replacement rather than cleaning, we source from the same manufacturers, which keeps warranties intact and turnaround short.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Mountain cedar pollen loading: San Antonio’s December-February Ashe juniper pollen season routinely breaks national records, and because your AC runs most of the year, that hyper-allergenic material cycles through your ducts continuously. Post-cedar-season cleaning removes what your filter couldn’t catch.
- Heat-baked flex duct liner: Attic temperatures above 140-155°F in summer cook the inner liner of flex duct until it sheds fibrous particulate directly into your airstream. Homeowners vacuum registers and wonder why dust returns in days. Camera inspection finds the real source.
- Moisture and mold at joints: Gulf moisture surges condense inside poorly sealed duct joints, especially in older South Side and near West Side homes with original metalwork. Cleaning without sealing leaves wet metal behind, and mold re-establishes within a season.
- Asbestos-containing duct tape on pre-1970s trunk lines: Homes in Monte Vista, Mahncke Park, and the near West Side built or re-ducted in the 1960s-70s often have sheet-metal trunks wrapped with asbestos tape. We identify this before any agitation or compressed air, then adjust scope and method to handle it safely.
Pricing for Air Duct Cleaning in San Antonio, FL
Most San Antonio homeowners pay between $350 and $650 for a complete residential air duct cleaning on a single-system home under 3,500 square feet. Larger homes, multiple HVAC units, or systems requiring extensive sealing work after cleaning can run $650-$950. Commercial properties start around $800 and scale with duct complexity and access difficulty. These are honest whole-system ranges, not per-vent teaser rates that balloon on the invoice.
What moves the needle: the number of HVAC zones, accessibility of your attic (steep pitches and tight scuttles add time), whether we find disconnected or crushed runs that need repair, and whether pre-1970s asbestos tape requires modified handling. We inspect first, quote in writing, and start only after you approve the exact figure. No surprises. Call (323) 918-4345 for a free estimate - we’ll ask a few questions about your home’s size and age, then give you a realistic range before we schedule.

FAQs About Air Duct Cleaning in San Antonio
Late February through April is ideal, right after mountain cedar pollen season peaks and before summer heat forces your AC into constant operation. Cleaning then removes the heaviest annual allergen load before your system enters its longest continuous run. Call (323) 918-4345 to book a post-cedar-season slot - estimates are free.
Yes. San Antonio’s rocky caliche and limestone substrate makes basements nearly impossible, so virtually all ductwork runs through unconditioned attics that exceed 140°F in summer. That heat degrades flex duct liner and concentrates debris accumulation in spaces most homeowners never enter. Our crews are trained to work safely in those conditions and to identify heat-damaged materials that need replacement, not just cleaning.
We reconnect or replace the damaged section, then seal with Guardsman mastic to prevent re-separation. In a 1968 Mahncke Park ranch we recently serviced, we found three runs flattened to near-zero airflow and two disconnected collars behind the air handler. After source removal and proper sealing, the homeowner’s master bedroom finally held temperature - she’d blamed the blower motor for years. Camera inspection finds these problems before we quote repair work.
We can, but we modify our approach first. Pre-1970s sheet-metal trunks wrapped with asbestos-containing duct tape require a scope change before any agitation or compressed air. We identify the tape during initial camera inspection, then use methods that don’t disturb the wrapping. We’ll explain exactly what we found, show you the image, and quote any adjusted procedure in writing before proceeding.
We follow NADCA source-removal protocols: negative pressure at the air handler, mechanical agitation of duct walls, HEPA collection of dislodged debris, and post-clean camera documentation. You get before-and-after footage, a photo of your clean home before we leave, and our 365-Day Done Right Promise in writing. If the job isn’t right, we make it right. Call (323) 918-4345 and ask Paul Adeyemi’s team what standard we hold ourselves to - we’re happy to walk through it.
