Air Duct Cleaning Services

Air Duct Cleaning Services refer to the full process of removing accumulated dust, pet dander, pollen, and debris from the supply and return ductwork that carries conditioned air through your San Antonio home. In our climate, where the AC runs from March through October and cedar pollen blankets the Hill Country every winter, duct interiors collect far more than most homeowners realize. A whole-home cleaning with Morton’s typically costs $450 to $900, and the price is written down before we start, not estimated after the fact.

Supply-Side Duct Cleaning

The supply ducts push cooled or heated air into every room, and they’re the ones that collect the fine dust you see on furniture. We clean each supply run with Rotobrush agitation equipment that loosens debris without damaging the duct walls. Then we extract it under negative pressure so it leaves the house entirely, not into your living room.

Return-Side Duct Cleaning

Return ducts pull air back to the HVAC unit and often hold more debris than supply runs because they draw unfiltered air from hallways and living spaces. In older San Antonio neighborhoods like Castle Hills and Kirby, we regularly find decades of dust, pet hair, and construction debris in return cavities. The return side gets the same Return Duct Cleaning treatment as the supply side, because half a clean doesn’t help anyone.

HVAC Duct Cleaning

HVAC Duct Cleaning is the cleaning of the full air-delivery system connected to your furnace and air conditioner, including the main trunk lines, branch ducts, and the plenum boxes at each end. When we clean HVAC ducts in San Antonio, we’re addressing the whole loop that air travels through every time your system cycles on – which, in a Texas summer, can be thousands of times a month. A typical HVAC duct cleaning costs between $450 and $900 depending on home size and system complexity, with the price set in writing before work begins.

Full-System Air Path Cleaning

Our Rotobrush and Nikro equipment reaches deep into the trunk line and branch runs, not just the first few feet at the register. We seal off each vent opening and pull the entire system under negative pressure while mechanically agitating the duct walls. That combination removes the film of dust that coats the inside of ductwork, not just the loose debris.

Plenum and Transition Cleaning

The plenum is the box where the ductwork meets the air handler, and it’s a spot that holds surprising amounts of dust and sometimes insulation fibers. In homes around Leon Valley and Live Oak, we clean the supply and return plenums as part of every HVAC duct cleaning. If the transition isn’t clean, the air passing through it picks up debris on every single cycle and spreads it through the house.

Vent Cleaning

Vent Cleaning covers the visible registers and grilles in your floors, walls, and ceilings, plus the first few feet of the duct run behind each one. These are the parts you see every day, and they’re where dust, pet hair, and cooking residue accumulate most visibly. In San Antonio, vent cleaning as a standalone service starts around $150, while a Full System Cleaning that includes all vents runs $450 to $900. We quote the exact number before we start, and that’s the number on the invoice.

Register and Grille Restoration

Floor registers in high-traffic areas collect dust, dog hair, and the occasional dropped Cheerio. We remove each register, clean it thoroughly, and wipe down the visible opening so it looks as good as it functions. In homes with kids and large dogs – which describes half of Alamo Heights – this step makes an immediate visual difference.

Bathroom and Kitchen Vent Care

Bathroom exhaust vents and kitchen range duct runs are part of the vent cleaning picture too, though they operate separately from the HVAC system. Lint, grease film, and humidity residue build up in these smaller runs and can reduce airflow. We inspect these vents during the job and let you know if they need attention, with a price before we touch them.

Air Duct Repair

Air Duct Repair addresses structural problems in your ductwork: separated joints, crushed flex runs, holes from rodents or construction, and sagging sections that restrict airflow. In San Antonio attics, where summer temperatures can exceed 140 degrees, duct tape adhesive breaks down and flex duct can pull apart at the connections. Repair costs vary by scope – simple joint resealing starts around $150 to $300, while replacing a collapsed section can run $400 to $900. We diagnose the problem, show you what we found, and give a written price for the fix before any repair work starts.

Leak Sealing and Joint Repair

A separated duct joint in a hot attic pulls 140-degree air into your conditioned airstream, which means your AC works harder and some rooms never get cool. We use mastic sealant and mechanical fasteners, not duct tape, to re-secure joints so they stay sealed. This is the most common repair we perform in Bulverde and Helotes, where hot attic conditions accelerate tape failure.

Crushed and Damaged Flex Duct Replacement

Flex duct gets crushed when someone crawls through an attic, when boxes are stacked on it, or when animals nest on top of it. A crushed run starves the room it serves of air, which is why one bedroom stays hot while the rest of the house is fine. We cut out the damaged section and install new flex duct properly supported and sealed, then rebalance airflow to the room.

Ductwork Cleaning

Ductwork Cleaning is the deep cleaning of the entire duct network – trunk lines, branch runs, risers, and drops – using powerful negative-air equipment rather than just brushing out what’s reachable by hand. San Antonio homes with pets, kids, or recent renovation work are prime candidates for this deeper service. Whole-home ductwork cleaning falls in the $450 to $900 range, and the scope is defined clearly before we start: number of systems, number of vents, and the condition of the ductwork itself.

Negative-Pressure Deep Extraction

Our Abatement Technologies negative air machine connects to the duct system and pulls a continuous vacuum while we agitate the interior with Rotobrush tools. That means dust is extracted at the source and removed from the house, not just loosened and left to resettle. The difference shows up within days – less dust on furniture, less sneezing, and a fresher smell in bedrooms.

Post-Cleaning Verification

Before we pack up, we walk through the house with you and show you the ducts we cleaned, including photos of the interior where access allows. We also photograph the areas we worked in so you can see that floors and furniture were protected and nothing was left behind. That’s the Cedarwell Care Promise in practice, not just in words.

Air Duct Inspection

Air Duct Inspection is a visual and equipment-assisted evaluation of your duct system to find leaks, blockages, mold, rodent activity, or excessive dust buildup before they become bigger problems. In San Antonio, an inspection is smart when you’re moving into a new home, after major renovation, or when some rooms consistently run warmer than others. A standalone inspection runs $150 to $300, and if we find work that needs doing, the inspection fee is credited toward the service.

Camera-Guided Interior Review

We run a small camera through accessible duct sections to document what’s inside: dust depth, debris, past water damage, or unwelcome animal activity. You get to see the images yourself, so you know exactly what we’re seeing and why we’re recommending what we recommend. No mystery, no pressure.

Leak and Airflow Assessment

We check visible duct joints in the attic and at the plenum, and we measure airflow at registers to identify rooms that are being starved. In houses around Lackland AFB and West San Antonio, we often find a single collapsed run or separated joint that explains a hot bedroom. Fixing that one problem can make a bigger comfort difference than cleaning every duct in the house.

Residential Air Duct Cleaning

Residential Air Duct Cleaning is the full cleaning of the duct system in a single-family home, townhouse, or condo, with procedures scaled to the size of the house and the number of HVAC systems. Most San Antonio homes have one or two systems, which puts residential duct cleaning in the $450 to $900 range. We treat every home the way we’d treat a neighbor’s house: shoe covers at the door, drop cloths under every work area, and the kids’ nap schedule respected.

Homes with Kids and Pets

Pet dander and kid-generated dust are two big reasons San Antonio families call us. Dog and cat hair gets pulled into return ducts and recirculates, while kids track in fine dust that settles into carpet and eventually the vents. A full residential clean removes that buildup, and we use pet-safe product choices whenever possible because we know the dog will be sniffing every corner after we leave.

Older Homes and Historic Districts

Homes in Monte Vista, King William, and other historic San Antonio districts often have duct systems that have been patched and modified over decades. They need careful handling – old registers, fragile grilles, tight attic access. We clean those systems gently and thoroughly, and we point out any repairs we see so you can plan for them, not get surprised by them.

Commercial Air Duct Cleaning

Commercial Air Duct Cleaning applies the same deep-cleaning process to offices, retail spaces, clinics, and small commercial buildings throughout San Antonio. Pricing for commercial jobs depends on the square footage, number of rooftop units, and duct complexity; most small commercial cleanings run $900 to $2,500. We schedule this work around your business hours when possible, and we provide documentation of the completed cleaning for building records.

Retail and Office Environments

Dusty ducts in an office mean employees sneezing at desks and a fine layer of dust on displays, equipment, and product. We clean after hours or before opening so your business keeps running without work interruptions. Our crew wears uniforms, signs in, and leaves the same respect for the space they’d show in a home.

Clinics and Care Facilities

Air quality matters more in medical and care settings, where patients and staff spend long hours inside. We use HEPA-filtered extraction with Abatement Technologies equipment to capture fine particles during cleaning, not just push them around. Documentation of the cleaning is provided for your facility records, and we work quietly to respect patient areas.

Brands We Service

We work on duct systems connected to any brand of HVAC equipment, and we’re particularly familiar with the ductwork configurations common in San Antonio homes with Trane, Carrier, Lennox, and Goodman systems. The ducts themselves matter more than the unit brand, and our Rotobrush and Nikro cleaning equipment is designed to handle residential flex duct, rigid metal duct, and everything in between.

We also use HEPA-filtered negative air machines from Abatement Technologies and Guardsman-branded cleaning tools on jobs where indoor air quality during the cleaning matters as much as the result. If you have a custom-built home, a converted attic, or a duct layout that’s seen better days, we can help. Whether your system is original to a 1980s house in Castle Hills or brand new construction in Bulverde, the ducts get the same thorough clean.

Signs You Need a Pro Right Now

• Dust returns within days of cleaning. If you wipe a shelf on Saturday and by Tuesday it’s coated again, the dust isn’t coming from outside – it’s being blown out of your ducts. A deep cleaning addresses the source, not the symptom.
• Rooms in the house are never the same temperature. A bedroom that’s always five degrees warmer than the hallway usually means airflow is blocked or leaking somewhere in the duct run. We find and fix the cause rather than just cranking the AC.
• You hear rattling or buzzing from the vents. Loose debris, detached dampers, or separated duct sections create noise when air moves past them. It’s a sign something inside the system needs attention before it gets worse.
• The house smells like the dog even after deep cleaning. Pet dander and hair accumulate in return ducts and recirculate through the house every time the system runs. Cleaning the ducts removes the source of the smell, not just the smell itself.
• Visible dust or debris at the register openings. If you can see fuzz, hair, or dust built up at the grille, there’s far more deeper in the duct run. It’s worth an inspection to know the scope before it becomes a bigger problem.

Our Process, Step by Step

1. 1
   We show up on time and protect your home first. Shoe covers go on at the door, drop cloths go down under every work area, and we walk through the house with you to note which rooms need access and which ones are off-limits for the dog or the napping toddler.
2. 2
   We inspect and explain before anything is opened. We look at the mechanical closet, the attic access, and a few registers, and we tell you exactly what we found and what we recommend. Then we give you a written price for the work before the work begins – that’s the number on the invoice, every time.
3. 3
   We clean the full duct system with professional equipment. Using Rotobrush agitation tools and a negative-air extraction machine, we loosen and remove dust, dander, and debris from the supply and return sides, the trunk lines, and each branch run. Dust leaves the house through the machine, not into your living room.
4. 4
   We clean up the work area and photograph everything. Before we leave, we vacuum and wipe the areas we worked in, and we take a photo of the clean-up so you can see the condition we left the house in. If anything isn’t right, you’ll see it in the photo and we’ll fix it on the spot.
5. 5
   We walk you through what we did and what we saw. We show you the before and after and answer any questions about airflow, repairs, or maintenance. You get the final invoice which matches the written estimate, and the 365-Day Done Right Promise goes into effect the day of the job.
