Trusted Air Duct Cleaning for Austin Homeowners
Air duct cleaning in Austin runs $349 to $689 for a standard single-family home, and most jobs wrap up in a single afternoon.

Cardinal Air Duct Austin is led by Omar Haddad and backed by the Relay Home Co. family, founded 2005. We hold every job to The Relay Visibility Guarantee: a live trackable arrival window, before-and-after photo proof, and a written price before a single duct is touched.

Air Duct Cleaning Services
Full System Cleaning covers the full path air travels through your home: the supply and return ductwork, registers, grilles, and the main trunk lines running through your attic or crawlspace. Most Austin homes need this every three to five years, but houses with shedding pets, recent remodeling, or allergy-prone residents benefit from more frequent cleanings. Cardinal Air Duct Austin handles the whole system with negative-pressure extraction – that means the loosened debris goes straight into a HEPA-filtered vacuum, not back into your living room. Typical pricing runs $349 to $689 depending on home size and the number of systems. Every job starts with a written price, handed to you before work begins.
Supply and Return Line Cleaning
We clean every supply and return line in the house, including the hard-to-reach runs feeding bedrooms and upstairs spaces. Our Rotobrush system agitates the duct walls while Nikro HEPA vacuums capture the loosened material at the source.
Register and Grille Detailing
Each register and grille gets removed, scrubbed, and reinstalled. You’d be surprised how much Austin dust and pet hair collects on the backside of these, and it keeps recirculating through your rooms until it’s cleaned.

HVAC Duct Cleaning
HVAC Duct Cleaning focuses on the ductwork connected to your heating and cooling system, including the plenum, main trunk, and branch lines that push conditioned air through the house. In Austin, where the AC runs for months at a stretch, these ducts accumulate a fine layer of dust that reduces airflow and forces your system to work harder. Cardinal Air Duct Austin cleans the full HVAC duct network as part of a standard air duct cleaning, typically $349 to $689 for a single-family home. The written price you receive before work starts is the price you pay – no add-ons at the door, no surprise line items after the tech is already inside.
Plenum and Trunk Line Cleaning
The plenum is the central chamber connecting your HVAC unit to the duct network, and it catches a lot of the debris that sneaks past the filter. We clean both the supply and return plenum thoroughly, then work through the main trunk lines with rotary brushes.
Evaporator Coil Contact Cleaning
Dusty ducts often mean a dusty evaporator coil, which sits above the furnace and blocks airflow when it’s caked over. We perform a light contact cleaning of accessible coil surfaces and recommend deeper HVAC servicing if the buildup is heavy.
Vent Cleaning
Vent Cleaning targets the visible openings where air enters and leaves your rooms: the supply registers, return grilles, and any dedicated ventilation points throughout the house. These vents collect a mix of Austin dust, pet dander, cooking residue, and pollen that’s pulled in every time a door opens. Cardinal Air Duct Austin removes every vent cover, scrubs it down, cleans the opening, and re-seats it properly. Vent cleaning is part of every air duct cleaning package, which runs $349 to $689 for most Austin homes. You’ll see the before-and-after photos of your own vents at the end of the job – that’s part of The Relay Standard.
Register Cover Restoration
We hand-clean every register cover, removing built-up grime from the fins and frame. Covers that are bent, rusted, or beyond cleaning get flagged for replacement, and we’ll quote the replacement cost before proceeding.
Return Air Grille Cleaning
Return grilles are where air gets pulled back into the system, and they’re often the dustiest spots in the house because every particle in the room passes through them. We clean both sides and check the filter slot for buildup that restricts airflow.
Air Duct Repair
Air Duct Repair fixes the leaks, gaps, and disconnected sections in your ductwork that quietly waste energy and pull unfiltered attic air into your home. In Austin attics, where summer temperatures regularly exceed 130 degrees, a leaky duct means you’re paying to cool the attic too. Cardinal Air Duct Austin identifies problem areas during cleaning and repairs them with proper sealing materials, mastic, and metal tape – not duct tape. The written price you get before work starts covers the repair scope, and every repair carries a written guarantee. If a repair fails, your second visit is free under the 365-Day Done Right Promise.
Disconnected Duct Reconnection
Sections of ductwork can separate during attic work, from settling, or from poor original installation. We re-secure disconnected runs, seal the joints properly, and confirm airflow is restored at the register.
Air Leak Sealing
Small gaps and pinhole leaks add up fast in a long duct run. We locate leaks, seal them with mastic or metal tape as the situation requires, and verify the fix holds before we finish the job.
Ductwork Cleaning
Ductwork Cleaning is the thorough cleaning of the entire duct infrastructure: the sheet metal or flex runs, the joints and elbows, the transition pieces, and the boots behind your registers. Over years of Austin AC use, these surfaces coat with a fine gray film of dust, dead skin cells, pest debris, and sometimes mold spores in humid seasons. Cardinal Air Duct Austin uses Rotobrush rotary agitation paired with Nikro HEPA-filtered negative-pressure vacuums to pull that material out without spreading it through the house. Standard ductwork cleaning for a typical Austin home runs $349 to $689. Your written price includes the full scope, agreed before any work starts.
Flex Duct Care
Many Austin homes built after 1990 use flexible insulated ductwork in the attic, and it needs gentler handling than rigid metal. We clean flex runs without tearing the inner liner – a common problem with careless cleaning that creates future leaks.
Rigid Metal Duct Restoration
Older Austin homes often have galvanized metal ducts that hold up better over time. Our rotary brush system scrapes the interior walls clean, and the HEPA vacuum captures everything so it exits the house instead of recirculating.
Air Duct Inspection
Air Duct Inspection is a camera-guided look inside your ductwork to identify problems before they become expensive repairs. We inspect for mold, pest activity, water damage, disconnected sections, and dangerous levels of accumulated debris. In Austin’s humid spring months, condensation inside poorly insulated ducts can create exactly the right conditions for mold, and a visual inspection catches it early. Cardinal Air Duct Austin includes an inspection with every air duct cleaning, so the $349 to $689 price covers both seeing what’s in there and getting it cleaned out. We use flexible camera scopes to document what we find, and you’ll see the images before we recommend any additional work.
Mold and Moisture Assessment
Dark staining inside ducts isn’t always mold – it can be years of candle smoke or cooking residue. We inspect the area, note active moisture, and if mold is suspected, we’ll guide you on proper testing and remediation steps before cleaning.
Airflow Verification
Blocked or collapsed duct runs starve certain rooms of conditioned air while others stay comfortable. Our inspection checks airflow at each register and flags restrictions, damaged runs, or closed dampers that explain uneven heating and cooling.
Residential Air Duct Cleaning
Residential Air Duct Cleaning is the full-home service for houses, condos, townhomes, and apartments across the Austin area. We clean the entire duct network, remove and detail every register, inspect the system with cameras, and leave the house with measurably better airflow. For most Austin single-family homes, residential air duct cleaning runs $349 to $689 based on square footage, number of systems, and how long it’s been since the last cleaning. Cardinal Air Duct Austin sends background-checked, uniformed technicians whose names you’ll know before they arrive – part of The Relay Standard booking experience. You get a trackable arrival window, photo documentation, and a digital invoice payable from your phone.
Homes with Pets
Dog and cat dander works its way deep into ductwork and gets redistributed through every room every time the system kicks on. Homes with shedding pets often need cleaning every two to three years, and we’ve seen dramatic reductions in visible dust after a thorough clean.
Allergy-Sensitive Households
For families dealing with allergies or asthma in Austin, clean ducts mean less particulate circulating through the living space. We recommend pairing a duct cleaning with a high-MERV filter upgrade – we stock Aprilaire and Honeywell filtration products and can install them during the same visit.
Commercial Air Duct Cleaning
Commercial Air Duct Cleaning covers offices, retail spaces, restaurants, medical facilities, and light industrial buildings throughout the Austin metro. The duct networks are larger, the systems run longer hours, and the stakes are higher: employee comfort, customer experience, and code compliance all depend on clean air delivery. Cardinal Air Duct Austin handles commercial projects with Abatement Technologies containment units to keep dust out of occupied spaces, and we schedule work around your business hours to minimize disruption. Commercial pricing depends on square footage, system complexity, and access conditions. We provide a written quote after an on-site evaluation, and that price does not change once work begins.
Restaurants and Food Service
Grease vapor and cooking residue from commercial kitchens migrate into ductwork and create a sticky film that traps dust. Regular commercial air duct cleaning reduces odor recirculation and keeps the dining room air fresh, which your customers notice.
Offices and Retail Spaces
High-density offices with dozens of computers and people generate constant dust and skin cells that end up in the ducts. We clean after hours or on weekends, and we use containment barriers so your business stays clean and operational during the work.

AfterBrands We Service
We service and install filtration products from Aprilaire and Honeywell, two of the most common names in Austin home HVAC systems. If you have an Aprilaire media cabinet or a Honeywell electronic air cleaner, our technicians can integrate a filter upgrade into your duct cleaning visit, and we stock replacement media for both brands on the truck.
For containment and air hygiene on larger jobs, we run Abatement Technologies negative air machines and HEPA containment equipment. That’s the same standard used in professional remediation work, and it’s one of the things that separates a serious air duct cleaning company from a guy with a shop vac. Whether you have Aprilaire, Honeywell, or any other make of HVAC equipment, we can clean and service the full system.
Signs You Need a Pro Right Now
- Visible dust blowing from registers when the system kicks on. That puff of dust when the AC starts is what’s been sitting in your ducts getting pushed into the room. It’s the clearest sign the ductwork is loaded and needs a full clean.
- Rooms that never reach the right temperature. Uneven heating and cooling often means airflow is restricted by debris or a duct run is disconnected. An inspection with our camera scope finds the cause fast.
- Unexplained allergy flare-ups at home. If symptoms ease when you’re away from the house and return when you’re home, the ductwork may be circulating irritants like dust mite debris and pollen that’s worked its way inside.
- Moldy or stale smell when the system runs. Austin’s humid summers create condensation inside poorly insulated ducts, and that moisture can support microbial growth. A musty smell from the vents is worth an inspection immediately.
- You just finished a renovation. Drywall dust and construction debris get pulled into the return ducts during any remodel, and that fine dust clogs everything downstream. Post-renovation duct cleaning protects the whole system.
Our Process, Step by Step
- 1
Written price and scope review. Before anything else, you get a written quote for the full job. We walk the system with you, explain what will be cleaned, what it costs, and what’s included. That price does not change at the door.
- 2
System protection and access prep. We lay down protective floor coverings where needed, open the main access points to the ductwork, and confirm the HVAC system is shut down for safety.
- 3
Rotary agitation and HEPA extraction. Our Rotobrush system mechanically agitates the interior of every duct run while the Nikro HEPA-filtered vacuum pulls everything out under negative pressure. Nothing blown into the house.
- 4
Register cleaning, inspection, and photo documentation. Every register and grille is removed and cleaned, then we run the camera scope through the main runs to verify the cleaning and capture before-and-after images for you.
- 5
Final walkthrough and digital invoice. We walk you through what we found and what we did, hand you the photo proof, and send a digital invoice you can pay from a link on your phone. If anything isn’t right, the 365-Day Done Right Promise covers it.
How Much Does Air Duct Cleaning Cost in Austin?
A standard air duct cleaning for a single-family home in Austin runs $349 to $689. Most three- to four-bedroom houses with one HVAC system land in the $400 to $550 range. Larger homes with multiple systems, finished attics with difficult access, or ductwork that hasn’t been cleaned in a decade can reach the top of that range. The main factors are the number of systems, the total duct length, the accessibility of the attic or crawlspace, and how heavily the ducts are loaded with debris.
Why Some Quotes Are So Much Cheaper
The industry’s bait-and-switch reputation exists for a reason: someone quotes you $79 and the invoice hits $1,200 once the technician finds “problems” that were never discussed. We don’t play that game. Your written price covers the whole job, and if we find something that needs attention, we show you the camera images and quote it separately before any additional work happens.
