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 HVAC Cleaning Across Hornsby Bend
HVAC cleaning in Hornsby Bend typically costs $350 – $650 for a complete system cleaning that includes the evaporator coil, blower motor, air handler, and all supply and return ducts. Most jobs take four to six hours, and Cardinal Air Duct Cleaning serves Hornsby Bend with a written price agreed before any work starts. We’re familiar with the unique conditions here along FM 973 and the Colorado River bottomlands, where airborne particulates from the Hornsby Bend Biosolids Management Plant settle into ductwork faster than in almost any other Austin-area community. If your vents are blowing weak or your home smells musty when the AC cycles on, call (737) 727-2314 for a free estimate.
Why Cardinal Air Duct Cleaning Is Hornsby Bend’s Preferred HVAC Cleaning Company
Hornsby Bend homeowners deal with something most of Austin doesn’t: the biosolids composting operation off FM 973 that releases fine organic particulates into the air. Those particles get pulled into return ducts, coating coils and blower wheels with a sticky film that plain filter changes will never address. Our technicians know what that buildup looks like and how to remove it properly. We’re held to The Relay Visibility Guarantee, which means every booking includes a live trackable arrival time, before-and-after photos of your actual ducts, and a digital invoice payable by link. Omar Haddad leads our Hornsby Bend crew, and he’s built the team around one standard: a homeowner should never guess what the job costs or whether the work was actually done. That’s why every job carries a written price before a single duct is touched and the 365-Day Done Right Promise: if the work isn’t right within a year, we return and correct it at no charge.
AC Vent Cleaning in Hornsby Bend
AC vent cleaning in Hornsby Bend is the process of removing built-up debris from your supply and return registers, the duct runs behind them, and the plenum boxes that distribute conditioned air through your home. Here, that debris tends to include fine organic dust from the biosolids plant off FM 973, plus the usual pet hair, skin cells, and construction dust from homes along Hunters Bend Road and Blue Bluff Road. A Hornsby Bend homeowner needs this when registers show visible dust accumulation, airflow drops at far bedrooms, or the house smells earthy whenever the fan kicks on. AC vent cleaning as part of a full HVAC cleaning runs $350 – $650 depending on system size and access.
Supply and Return Register Care
We remove each register, clean it with rotary brush agitation, and wipe the register boot where dust cakes along the edges. In Hornsby Bend homes with long flex runs to distant bedrooms, that boot area is often the first place airflow chokes.
Debris in the Plenum Box
The plenum is the metal box that sits between your air handler and the duct trunk line. It collects whatever the filter misses, and in this part of Travis County that often means a fine tan powder that never fully vacuumed away with a household machine. We clean it at the source so it stops recirculating.
Furnace Duct Cleaning in Hornsby Bend
Furnace duct cleaning in Hornsby Bend matters even if you mostly run the AC, because the same duct system carries heated air all winter along Webb Lane and Gilbert Road. The job involves cleaning the full supply and return duct network, the heat exchanger surface, and the blower assembly that pushes air through the house. A Hornsby Bend homeowner needs it when the furnace short-cycles, registers blow weak even after filter changes, or a fine dust settles on furniture within days of cleaning. Furnace duct cleaning here runs $350 – $650 as part of a complete system cleaning, and we give you that number in writing before any work begins.
Heat Exchanger Surface Cleaning
The heat exchanger is the metal chamber where combustion gases heat the air that warms your home. When organic dust from the Hornsby Bend area coats that surface, it reduces heat transfer and can produce a faint burning smell at the start of each heating season. We clean it carefully without damaging the exchanger.
Blower Assembly and Motor
Your blower motor is the heart of the system. In Hornsby Bend, the fine particulates from the biosolids plant pack onto blower wheel fins and reduce airflow at every register. We remove the wheel, clean each fin, and check the motor’s amp draw before reinstalling.
Trusted Brands We Service in Hornsby Bend
We clean and service all major HVAC brands, and we stock common replacement filters and parts for Hornsby Bend customers, including Aprilaire media filters and Guardsman UV systems. Our trucks carry Rotobrush rotary brush systems and Abatement Technologies containment units, so we can handle everything from a single clogged return on Hunters Bend Cove to a full commercial-size duct network without subcontracting. Keep your system manufacturer’s name handy when you call (737) 727-2314, and we’ll confirm coverage before the technician arrives.
Common HVAC Cleaning Problems We See in Hornsby Bend Homes
- Biosolids plant residue inside ducts. Homes within two miles of the Hornsby Bend Biosolids Management Plant off FM 973 routinely show a fine organic film on duct interiors that simple vacuuming never fully removes. We use negative-pressure extraction with HEPA filtration so that film goes into the vacuum, not back into your living room.
- Clogged blower wheels cutting airflow. The blower sits after the filter in most systems, which means it catches whatever the filter misses. In Hornsby Bend, that often means a packed wheel within three years of a new install.
- Mold spotting on evaporator coils. The humidity along the Colorado River bottomlands keeps coils damp longer each cycle, and organic dust landing on a wet coil is a recipe for mold. Coil cleaning and treatment is a standard part of our HVAC cleaning here.
- Flex duct compression in older homes. Homes built in the 1990s and 2000s along FM 969 and Blue Bluff Road often have flex duct runs that have been compressed or kinked by attic work. We flag that during cleaning, because a kinked duct will never move air no matter how clean it is.
Pricing for HVAC Cleaning in Hornsby Bend, TX
A complete HVAC cleaning in Hornsby Bend runs $350 – $650 for a typical single-family home with one air handler. That covers the evaporator coil, blower motor and wheel, air handler cabinet, plenum, and all accessible supply and return ducts, including AC vent cleaning and furnace duct cleaning. Larger square footage, multiple air handlers, or an attic with limited access pushes the price toward the top of that range. We do not charge per vent, ever. You get one flat per-system price on a written estimate before any work starts, and that number does not change at the door. Call (737) 727-2314 for a free estimate on your Hornsby Bend home.

FAQs About HVAC Cleaning in Hornsby Bend
Most Hornsby Bend homes need full HVAC duct cleaning every three to five years, but homes within two miles of the biosolids plant off FM 973 often need it every two to three years because organic particulates accumulate faster. Call (737) 727-2314 and we’ll help you figure out whether your system actually needs it or can wait.
One flat price for the whole system, always. We write the price before any work starts, and per-vent pricing does not exist in our company. That means your $350 – $650 covers every duct in the house, not a teaser count-and-upsell when the technician arrives.
The Hornsby Bend Biosolids Management Plant releases fine organic particulates that drift over nearby neighborhoods and settle into outdoor condenser coils and indoor return ducts faster than typical Austin dust. That organic material holds moisture and can accelerate coil mold growth inside your air handler. A full cleaning every two to three years keeps it in check. Call (737) 727-2314 for a quote.
Yes, every Hornsby Bend job includes before-and-after photos of your actual duct interiors, coil, and blower assembly. The Relay Standard requires it: you get photo documentation of exactly what we found and what it looks like when we finish.
We connect a HEPA-filtered negative-air machine to your duct system, agitate debris with a Rotobrush rotary brush to loosen it from duct walls, then extract it under vacuum so nothing recirculates into your home. After the ducts are clean, we remove and clean the blower wheel, clean the evaporator coil, treat the coil surface, and check airflow at the registers. The job ends with a written summary and photos. Call (737) 727-2314 to schedule.
