Frequently Asked Questions - Air Duct Cleaning in San Antonio, TX
Straight answers to the questions San Antonio homeowners ask us most about air duct cleaning, pricing, and what to expect when our crew arrives.
Pricing & Cost FAQs
Air duct cleaning in San Antonio typically runs between $300 and $550 for a whole-home system, depending on square footage, the number of supply and return vents, and how long it's been since the ducts were last cleaned. Homes in older neighborhoods like Alamo Heights and Terrell Hills, where ductwork can date back several decades, sometimes fall at the higher end because of heavier buildup. We give one flat price per system in writing before any work starts, so the number you approve is the number you pay. For an exact quote on your home, call (430) 233-7681.
Low quotes in the San Antonio market usually come from companies that price per vent and then find a way to add on charges once they're inside the home. That's the bait-and-switch pattern this industry has a reputation for. A whole-system price from a reputable company includes the actual cleaning, not just a quick vacuum of the visible register openings. We charge one flat price per system, agreed to in writing before our tech ever walks through your door. That number covers the full job.
We charge per system, never per vent. Per-vent pricing is how homeowners in Windcrest and Converse end up with a $99 coupon that becomes a $700 invoice. Our written estimate covers the entire duct system, both supply and return sides, for one flat price. You'll know the total before we start, and there's no surprise line item at the end.
Three main things move the price: the size of the home, the number of vents and returns, and the level of contamination. San Antonio's climate adds another variable. Our long, dry summers blow dust and pollen through return air grilles, and our humidity can create conditions where mold grows inside ducts, especially in homes near the Medina River or along Salado Creek. Those jobs require more time and different equipment. We'll explain exactly what we found and quote accordingly.
Yes. The price we put in writing before work begins is the price you pay. That's Threshold Standard practice at every Linden Air Duct Cleaning location, including San Antonio. If our tech finds something unexpected mid-job, like a collapsed duct or a pest issue, we stop, show you what's happening, and agree on any change in writing before proceeding. No one gets surprised by an invoice.
Service & Process FAQs
A typical visit takes two to four hours. We start by walking the home with you to count vents and returns and note any problem areas. Then we connect a high-powered vacuum to the main trunk line, seal the registers, and use rotary brushes and compressed air to dislodge debris from the duct walls. The vacuum captures everything at the source. Afterward, we show you before-and-after photos of your own ducts so you can see the work was actually done.
Yes, both sides. The return side pulls air from your rooms back to the HVAC unit, and in San Antonio's cooling season it runs constantly, pulling dust, pet hair, and skin cells through the grilles. The supply side pushes conditioned air back out. Cleaning only one side leaves the other full of the same debris that just gets re-circulated. A proper job addresses the complete system.
Most single-family homes in San Antonio take between two and four hours. Larger homes in Fair Oaks Ranch or Castle Hills with multiple HVAC systems can take a full day. We'll give you a time estimate on the phone based on your square footage and system count, and we'll confirm it when we arrive.
You'll need to be there when we arrive and for a few minutes at the end, but you don't have to stand over the tech's shoulder the whole time. We do ask that someone 18 or older be present during the visit. Many San Antonio homeowners use the time to work in another room or sit outside. We'll check in before we leave and walk you through everything we did.
No. We run vacuum collection at the point of contact, which means debris is pulled into sealed containment, not blown into your living room. We lay down corner guards and floor protection at the entry, and our techs wear clean shoe covers indoors. Homes in Leon Valley and Kirby with light-colored carpet are a daily part of our schedule, and we treat every floor like it's our own.
Yes. Two-story homes are common all over San Antonio, from newer builds in Selma to established streets in Alamo Heights. We run our equipment up to the second floor and clean both levels in the same visit. The price reflects the full system, both stories included, with no per-floor upcharge.
Brands & Equipment FAQs
Our San Antonio crews use professional-grade duct cleaning equipment from Abatement Technologies and Rotobrush. These are the brands serious remediation and HVAC contractors run, not the small portable units rented from a home improvement store. The combination of a high-powered negative-air vacuum and a rotary agitation brush lets us pull debris while scrubbing the duct walls, which is what actually removes the film that sticks inside trunk lines.
They're not. The difference comes down to suction power and agitation. A shop-style vacuum connected to a small hose can reach a few feet into a vent and that's it. The negative-air machines we run, built by companies like Abatement Technologies, create enough airflow to pull debris from the entire trunk line while our brush and air tools knock it loose. That's why the equipment conversation matters when you're comparing quotes in San Antonio.
Only when the job calls for it, and only with your approval. Most duct cleaning in San Antonio doesn't require chemical products. When we find microbial growth, which happens in humid seasons or after a leak, we'll talk to you about options and what's safe for your household before applying anything. If you'd prefer a mechanical cleaning with no chemical products at all, we're glad to do exactly that.
Licensing & Insurance FAQs
Linden Air Duct Cleaning operates as a Threshold Verified location. Every technician who works under our name is required to hold the licenses and carry the insurance their state and trade require. Before your visit, we'll send you the name and photo of your tech, and they'll show a photo ID badge at the door. That's the promise we make to every San Antonio homeowner.

Because we told you they were coming before they arrived. When you book a job with us, you get the technician's name and photo in advance.

Emergency & Response FAQs
Duct cleaning is a scheduled service, not a same-day emergency call, so we don't promise emergency dispatch. What we do offer is a standing appointment window Monday through Friday from 7:00 AM to 7:00 PM and Sunday from 7:00 AM to 7:00 PM, closed Saturday. If you have water in your ducts or visible mold, call (430) 233-7681 and we'll get you on the schedule as soon as possible.

DIY vs. Professional FAQs
You can clean the visible register openings and swap your HVAC filter, but that touches less than a foot of the system. The duct runs inside your walls and attic space in San Antonio homes hold years of dust, pet dander, and sometimes mold, and reaching them properly takes a commercial vacuum and agitation equipment. A homeowner changing a filter is maintenance. Cleaning the full duct system is a job for a professional crew with the right machines.
Your filter catches particles as air enters the HVAC unit. Your ducts are the highway those particles travel through over years. The filter can't touch what's already stuck to the duct walls or sitting in the trunk line. San Antonio's dust season runs long, and in neighborhoods with mature trees, like Terrell Hills, the fine organic particulate builds up fast. A filter swap is monthly maintenance; duct cleaning is a periodic deep clean of the whole system.
Warranty & Guarantee FAQs
Every job we perform in San Antonio falls under the Threshold Verified guarantee: background-checked and identity-verified technicians, name and photo sent before the visit, photo ID badge at the door, clean marked uniform, and a written price before work starts. If any technician arrives who you were not told to expect, that visit is on us and we make it right. We also stand behind the quality of the cleaning itself and will return to address any reasonable issue with the work.
You'll see it. After we finish, we show you before-and-after photos of your own ducts, taken with our inspection camera. You'll see the condition before we started and the same duct after cleaning. That evidence is yours to keep, and it's the same proof we'd want if it were our house in Windcrest or Castle Hills.
Most San Antonio homes benefit from air duct cleaning every three to five years. Homes with pets that shed heavily, recent construction or renovation, or residents with allergies or asthma may want it more often. If you've just moved into an older home in Alamo Heights or Leon Valley and you don't know when the ducts were last touched, that's a good time to start fresh. Our team can inspect and give you an honest recommendation, not a hard sell.
