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.

Furnace Cleaning in Leander
Furnace cleaning in Leander is about more than vacuuming the return registers. It means pulling the blower assembly, cleaning the evaporator coil and blower wheel, brushing the heat exchanger surfaces, and treating the coil so it sheds dust rather than holding it. Most Leander homes built before 2010 have furnaces that run about 1,800 to 2,200 hours a season, and the blower wheel picks up a visible layer of gray fuzz every few years. A typical furnace and blower cleaning in Leander runs $225 – $385 as part of a full HVAC cleaning.
Heat Exchanger Care
A clogged blower wheel reduces airflow across the heat exchanger, and that makes the furnace run hotter than it should. We brush and vacuum the exchanger surfaces during the cleaning, which lets the system move heat the way it was designed to. If you’ve noticed the furnace cycling more often than it used to, this is often the first culprit we find.
Blower Motor and Squirrel Cage
The blower cage is where fine dust packs on and throws the wheel out of balance. We remove the blower assembly, clean each blade, and check amp draw before and after. On a Leander home where the blower was drawing high amps from a dust-loaded wheel, the drop after cleaning tells the real story, and we write those numbers on the invoice.
AC Vent Cleaning in Leander
AC vent cleaning in Leander gets to the layer of dust, hair, and construction debris that settles inside duct runs and on register boots. The work is source removal, not a wipe-down. We agitate the interior walls with a Rotobrush system and pull everything to a Nikro HEPA vacuum under negative pressure, so loosened debris goes straight into containment, not back into your living room. A typical whole-home AC vent and duct cleaning in Leander runs $425 – $685 for one system.
Register and Boot Cleaning
Registers and boots trap a surprising amount of what lands in ducts, especially in homes with pets or carpeted second stories. We remove each register, clean the boot by hand, and reseat it properly. It’s the difference between a cleaning that lasts and one where dust returns in a few weeks.
Flex Duct Inspection on Newer Builds
This matters specifically in Leander’s fast-growth subdivisions. Newer slab homes west of the Ronald Reagan corridor often have flex duct runs that were crushed or kinked at the plenum during the original build. We camera-inspect before cleaning, and if we find a collapsed collar, we say so and reseal it. Cleaning a crushed duct without fixing the restriction is wasted money.
Trusted Brands We Service in Leander
Our technicians work on all major residential equipment and we stock common filters and parts for Leander jobs, which keeps turnaround short when a blower motor or coil tray needs replacement. Whether your system is a Trane, Carrier, Lennox, Rheem, or Goodman, we use the same professional-grade approach: Rotobrush for agitation, Nikro for HEPA extraction, and Abatement Technologies containment units when a job requires isolating the air handler. For filtration upgrades, we carry Aprilaire media cabinets and Guardsman electrostatic filters, both of which hold up well during Leander’s heavy spring pollen and fall ragweed stretches.
Common HVAC Cleaning Problems We See in Leander Homes
- Crushed flex duct in 2015-plus subdivisions. Leander’s building boom west of Ronald Reagan meant fast construction, and flex duct runs sometimes got pinched at the plenum before the drywall went up. A camera inspection finds it; a surface cleaning doesn’t.
- Dust-packed blower wheels from limestone and construction dust. Leander sits on Edwards Plateau limestone, and new-home construction leaves fine white dust in ducts for years. That dust packs onto blower wheel blades and drops airflow fast.
- Retrofitted returns on original Old Town and early-2000s homes. Older Leander homes often have return air paths that were retrofitted, not designed. That means higher static pressure, more dust pulled through wall cavities, and coils that load up faster than they should.
- Pollen inside the duct system, not just on the filter. Leander’s cedar and ragweed seasons push fine pollen past standard one-inch filters and into the coil and ducts. Once it’s in the duct lining, it recirculates every time the system runs.

FAQs About HVAC Cleaning in Leander
Most Leander homes genuinely need a full duct and coil cleaning every 4 to 6 years, with two local exceptions: homes built during the 2015-and-later subdivision boom often benefit from a one-time cleaning around year two or three because construction dust is still working its way through the system, and homes with multiple pets or cedar-heavy exposure may need it every 3 years. If you just moved into a new-build home in Leander, check the cold-air returns for drywall dust. If you see it, the ducts are carrying it too. Call (737) 727-2314 for an honest assessment.
No. We quote one flat price per system, in writing, before any work starts. Per-vent pricing on a Leander two-system house can quietly turn a $99 teaser into a $900 invoice mid-job. That’s exactly the bait-and-switch pattern we refuse to run. One price, one system, agreed at the door.
You get photos of the supply plenum, return drop, blower wheel, evaporator coil, and a representative section of duct before we start, then the same locations after cleaning. These are your ducts, not stock images. If the coil was matted and is now clean metal, you’ll see it. If a crushed flex duct collar needed resealing, that’s in the photos too. It’s the proof that the job we quoted is the job we did.
We schedule HVAC cleanings as routed appointments, not emergency calls, so same-day service isn’t something we promise. What we do guarantee is a live, trackable arrival window on your phone and a written price before work starts. Call (737) 727-2314 and we’ll get you on the schedule for the next available date.
We clean the furnace and blower motor as part of a full HVAC cleaning. That means the blower wheel, blower housing, evaporator coil, heat exchanger surfaces, and the duct runs all get cleaned in the same visit. A duct-only cleaning without the blower is half a job, and we don’t quote half a job.
What a Real HVAC Cleaning in Leander Actually Involves
Leander’s building stock straddles two very different eras. There’s the older, smaller housing in the original downtown and Old Town grid, much of it built when central air was retrofitted into homes designed for window units. Those systems often have undersized return air paths, which means higher static pressure, more dust pulled through wall cavities, and a coil that loads up fast. Then there’s the massive 2015-and-later subdivision build-out west of the Ronald Reagan corridor, where slab foundations and fast framing produced a different set of problems: flex duct runs crushed or kinked at the plenum during construction, drywall dust settled deep in the boots, and air handlers sealed up tight behind closet doors.
Those two housing types fail differently, and they need different attention. Our tech pulled up to a two-story in Bryson and found the return-side static pressure way high. A camera inspection of the air handler showed a crushed flex duct collar at the plenum, likely pinched during the original build. After source removal with agitation tools under negative pressure and HEPA filtration, plus a resealed collar, the blower motor amp draw dropped and the homeowner could feel real airflow at the upstairs registers for the first time. That’s the kind of detail you only catch if you look before you clean.
The reason we push camera inspection and before-and-after photos so hard is simple: in Leander, the difference between a real cleaning and a register wipe-down is hundreds of dollars and months of recirculated dust. A technician who only wipes the visible registers and tells you the ducts are clean hasn’t touched the blower, the coil, or the inside of the duct runs. The dust returns in weeks, and you’ve paid for a placebo. We’d rather show you the duct walls before and after and let you decide if the job was done right.
