AfterResidential Duct Cleaning in San Antonio, TX
Residential duct cleaning in San Antonio typically costs between $350 and $650 for a full single-family home, with most jobs completed in 3 to 5 hours. That range covers a complete Air Duct Cleaning: supply and return ducts, registers, the air handler, and the main trunk lines. If you’re calling around San Antonio and getting quotes far below or far above that window, it’s worth asking exactly what’s included, because not every company cleans the same components.
At Mortons Air Duct San Antonio, we clean homes across the city, from Alamo Heights to Stone Oak to the older neighborhoods around Woodlawn Lake. We’re part of the Air Duct Cleaning in San Antonio specialists who focus on one thing: getting the air moving through your house clean and efficient, without leaving a mess behind. The work is backed by the 365-Day Done Right Promise, which means if it’s not right, we make it right. Full stop. Call (903) 354-8393 and you’ll get a real person on the line, any hour, who can schedule a free estimate.
You can also read more about how this fits into the broader picture on our home page, but here’s the short version: this is what we’ve done since 2005, and every job still starts the same way, with a written price before anything gets touched.
When You Need Residential Duct Cleaning
Most San Antonio families call us when something in the house feels off. Here are the situations we hear most often, and what they usually mean for the ducts:
- Dust returns within a day or two of wiping surfaces. In San Antonio, a lot of our dust is fine caliche and pollen that enters through attic duct leaks or gets pulled into the return. If the ducts are lined with old debris, the system redistributes it every time the AC kicks on.
- One or two rooms never hold temperature. The Alamo City’s long cooling season means your AC runs hard from May through October. Blocked or collapsed duct runs in the attic, common in homes in older areas like Jefferson and Beacon Hill, starve those rooms of airflow.
- You moved into a house with renovation history. Drywall dust, sawdust, and paint overspray settle into ductwork and stay there. The previous owner’s kitchen remodel in Terrell Hills or a bathroom gut in Monte Vista becomes your airflow problem.
- Allergy symptoms spike at home. San Antonio’s mountain cedar season is brutal, but when symptoms ease at work and flare at home, the ducts are often holding pollen and dust from previous seasons and feeding it back into the living space.
- You have pets that shed heavily. Hair and dander get pulled into return grilles and coat the inside of duct walls. Homes with multiple dogs or cats, especially long-haired breeds, benefit from a duct cleaning every 2 to 3 years rather than the typical 3 to 5.
- The house smells musty or stale when the AC first starts. That first blast of air carries whatever has settled in the ducts. In humid San Antonio summers, dust and moisture in the ductwork can produce a smell that no amount of candles or plug-ins fixes.
If you notice any of these and want a professional assessment, call (903) 354-8393. We’ll tell you honestly whether a duct cleaning is the right move or if something else is going on.
Our Residential Duct Cleaning Process
Here’s exactly what happens when our crew arrives, step by step, so you know the plan before it starts. We also offer a Video Inspection so you can see the condition inside your ducts first.
- Protection first, always. Our technicians put on shoe covers at the door and lay drop cloths along the path to the equipment and the registers. Floors, furniture, and pet areas are protected before any tools come out. This is part of the Cedarwell Care Promise, and it’s not optional.
- Walk-through and written price. We inspect the system, count registers, check the air handler location, and note any access issues. Then we hand you a written price. No work starts until you’ve seen the number and said go.
- Negative-pressure cleaning with Rotobrush equipment. We connect a HEPA-filtered vacuum system to the main trunk line to create negative pressure, then run rotating brushes through every duct run. The equipment we use is professional-grade, the same brands used by commercial contractors, because rental gear doesn’t get the same result.
- Register and grille cleaning. Each register and return grille is removed, cleaned, and wiped down before going back in place. We do this carefully and quietly, which matters if a baby is napping or a dog is already uneasy about strangers in the house.
- Air handler and blower cleaning. The blower compartment and evaporator coil area get cleaned and inspected. In San Antonio’s humidity, this is where dust and moisture combine, and leaving it untouched means the clean ducts won’t stay clean for long.
- Photo of the clean-up before we leave. Before the crew packs up, we photograph the work area so you can see the space is clean and protected. You get that proof on the spot. Then we walk you through what we found and what was removed.
Every step is done by background-checked, uniformed technicians who work to the C.A.R.E. values: courteous, accountable, respectful, and efficient. We run quieter equipment when we can, and we’ll work around nap schedules if you tell us in advance.
Residential Duct Cleaning Pricing in San Antonio
Here’s the pricing picture in San Antonio, based on what we see across the city. These are honest ranges for a single-family home; your exact price depends on home size, system age, and how much buildup has accumulated.
| Home Size | Typical Price Range | What’s Included |
|---|---|---|
| Up to 1,500 sq ft | $350 – $450 | All supply and return ducts, registers, main trunk line, air handler inspection |
| 1,500 – 2,500 sq ft | $450 – $600 | Everything above, plus full air handler and blower cleaning |
| 2,500 – 4,000 sq ft | $600 – $850 | Everything above, plus cleaning of both systems if the home has dual-zone HVAC |
| Over 4,000 sq ft | $850 – $1,200+ | Full system clean, additional returns, extended duct runs |
What affects the price in San Antonio specifically? Attic access matters. Homes in newer subdivisions around Cibolo and Schertz often have walk-in attics that are easier to work in, while older houses in Alta Vista or Olmos Park might have tight crawlspace access that takes longer. The number of returns also matters, and so does how long it’s been since the last cleaning. A system that hasn’t been touched in ten years takes longer than one cleaned three years ago.
We don’t charge more than the written quote, ever. That’s the whole point of the upfront pricing. Call (903) 354-8393 for a free estimate, and you’ll have a number before you have to decide anything.
How Morton’s Air Duct San Antonio Stands Out
You have options for duct cleaning in San Antonio, so here’s what we think actually matters when choosing a crew to work inside your home:
The 365-Day Done Right Promise. If the job isn’t right, we make it right. This is stamped on every job, not offered when asked. When you spend anywhere from $350 to over a thousand dollars on a service you can’t easily see, that promise is the whole ballgame.
Written price before work starts. No surprises on the invoice. If we find something during the walk-through that changes the scope, we tell you before touching it. The price you approve is the price you pay.
Equipment that actually cleans. We use professional systems, including Rotobrush brush-and-vacuum technology and Nikro HEPA-filtered negative air machines. In homes with significant dust and dander, like ones with German Shepherds or retrievers, this level of equipment makes a visible difference in what we pull out. We also work with filtration and air quality equipment from brands like Honeywell and Aprilaire when a home needs more than just duct cleaning.
The Cedarwell Care Promise. Morton’s Air Duct San Antonio is an independently owned member of the Cedarwell family of companies. That means every visit includes the same commitments: shoe covers and drop cloths, uniformed and background-checked technicians, and a photo of the clean-up before the crew leaves. It’s a system, not a slogan.
A live person answers, 24/7. Most companies route you to voicemail after hours. Ours is a human. Call at 11 p.m. and ask a question, and someone’s there. That’s rare in home services, and it matters when you’re trying to plan around a family calendar.
Founded in 2005, Morton’s Air Duct San Antonio has spent two decades doing exactly this one thing. Paul Adeyemi leads the team, and he’s the one who set the standard: treat every home like your kids and your dog live there. Because ours do, and so do yours.
FAQs – Residential Duct Cleaning
How much does residential duct cleaning cost in San Antonio?
Residential duct cleaning in San Antonio typically costs between $350 and $650 for most single-family homes, with larger homes or heavily soiled systems running up to $1,200 or more. The price depends on home size, the number of returns, attic access difficulty, and how long it’s been since the last cleaning. Call (903) 354-8393 for a free estimate with a written price before any work starts.
How long does residential duct cleaning take?
Most residential duct cleanings take 3 to 5 hours for a standard single-family home in San Antonio. Larger homes with dual-zone systems or heavy buildup can take a full day. We can give you a time estimate during the walk-through, and we’ll work around nap schedules if you let us know in advance.
How often should I clean my air ducts in San Antonio?
Every 3 to 5 years is the general guideline, but San Antonio’s climate and local conditions can shorten that. Homes with pets, homes near construction zones like the growth corridors along 1604, and households with allergy sufferers often benefit from cleaning every 2 to 3 years. If mountain cedar season hits your family hard, a fall cleaning before cedar starts in December can make a noticeable difference.
Is residential duct cleaning worth the money?
For most San Antonio families dealing with visible dust, pet dander, renovation debris, or allergy symptoms tied to being at home, yes, residential duct cleaning is worth it. It removes the buildup that keeps recirculating through the living space, and it gives your HVAC system cleaner airflow to move. We’ll tell you honestly during the walk-through if your ducts actually need cleaning or if the issue lies elsewhere.
Will duct cleaning make a mess in my house?
Not with our crew. We put down drop cloths along the entire work path, wear shoe covers from the moment we step inside, and use negative-pressure equipment that traps the debris we remove rather than blowing it around. Before we leave, we photograph the clean-up so you can see the house was left protected and clean. That’s the Cedarwell Care Promise, and it’s part of every single visit.
Do you clean the air handler and blower too?
Yes. We clean the blower compartment and evaporator coil area as part of our standard residential duct cleaning. Leaving those untouched means dust and debris from the air handler simply re-enters the freshly cleaned ducts. In San Antonio’s humid climate, this step matters even more because moisture and dust combine to create buildup that affects both air quality and system efficiency.
