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 Leon Valley
HVAC cleaning in Leon Valley typically costs $350 – $650 for a full-system cleaning of a standard 1,500 – 2,500 sq ft home, and most jobs are completed in a single visit. That price covers the entire system: supply ducts, return ducts, air handler, blower, and AC coil.

We know Leon Valley homes. We know the 1950s ranches off Evers Road, the brick bungalows near Huebner Creek, and the newer construction west of Bandera. More importantly, we know what’s inside those walls: duct runs that have been collecting dust for decades. Our HVAC Cleaning team works throughout Leon Valley, from the Forest Oaks area to the neighborhoods around Raymond Rimkus Park. Scheduling is coordinated from the brand’s San Antonio office, and crews serve Leon Valley locally.
Why Cardinal Air Duct Cleaning Is Leon Valley’s Preferred HVAC Cleaning Company
Leon Valley homeowners keep calling us back because we do something most duct cleaners won’t: we hand you a written price for the whole system before we touch a single duct, and that price does not change at the door. No per-vent pricing, no bait-and-switch, no “we found a problem” upcharge. The price we quote is the price you pay.
Every technician who shows up in Leon Valley is background-checked, uniformed, and you’ll know their name before they knock. They run professional-grade equipment: Nikro HEPA vacuums for negative-pressure extraction, Rotobrush rotary brush systems, and Abatement Technologies containment units when the job calls for it. That means the loosened debris goes straight into the vacuum, not back into your living room.
We back every job with the 365-Day Done Right Promise. If the work isn’t right within a full year, we return and correct it at no charge. That’s not a limited-time offer or a conditional warranty. It applies to every booking in Leon Valley, without exception.
Furnace Duct Cleaning in Leon Valley
Furnace Duct Cleaning in Leon Valley homes means pulling every register, agitating the branch ducts with a rotary brush, extracting debris under negative pressure, and cleaning the blower assembly itself. It runs $350 – $600 for a typical Leon Valley home, depending on system size and the number of branches. We agree on that number before work starts.
Here’s the thing about Leon Valley specifically: most of these homes were built between the 1950s and 1970s, and many sit on pier-and-beam foundations with short, unsealed return runs. Those return runs pull attic dust and lawn-mowing dust straight into the air handler. The dust problem here is structural, not seasonal. You’re not just cleaning what fell in through the registers – you’re cleaning what the foundation design actively pulls in.
Return-Side Debris Removal
The return side is where Leon Valley homes collect most of their debris, because those unsealed runs under the house and through the attic are wide open to whatever’s floating by. We don’t skip the return to save time. We camera-inspect the return pan, seal what needs sealing, and clean the full run back to the air handler.
If your return pan isn’t sealed to the furnace, debris migrates down the lint pathway regardless of how clean your registers look. We check that connection on every furnace duct cleaning in Leon Valley.
Blower and Air Handler Cleaning
The blower motor is where the dust actually accumulates. By the time you see dust on your registers, the blower wheel is usually carrying a layer that’s reducing airflow and forcing your system to work harder. We remove the blower, clean the wheel and housing, and photograph it before and after so you can see what was actually there.
AC Coil Cleaning in Leon Valley
AC Coil Cleaning in Leon Valley usually runs $150 – $300 when done as part of a full system cleaning, and $200 – $350 as a standalone service. A dirty evaporator coil is the single biggest efficiency killer in a Texas AC system, and in Leon Valley’s summer heat, a coil with even a light dust blanket costs you real money every month on your CPS Energy bill.
When the coil is dirty, the refrigerant can’t absorb heat properly. The system runs longer, the compressor works harder, and the house still doesn’t reach the setpoint. Cleaning the coil isn’t an upsell – it’s the part of the job that actually makes your AC work again.
Evaporator Coil Cleaning
The evaporator coil sits inside the air handler, right where the return air hits it. In Leon Valley homes with unsealed returns, that coil becomes a dust magnet. We remove the coil panel, apply a professional-grade coil cleaner, and flush the fins until they’re clean enough to photograph and show you.
We do not use a garden sprayer to “rinse” the coil and call it done. The coil gets treated properly, and you get before-and-after photos of it.
Condenser Coil Cleaning
Most Leon Valley homes keep the condenser outside, where it eats grass clippings, dirt, and the fine gray dust that kicks up during every dry spell. A clogged condenser coil raises head pressure and shortens compressor life. We clean the condenser coil from the inside out, not just the surface you can see from the yard.
Trusted Brands We Service in Leon Valley
We clean and service all major HVAC brands found in Leon Valley homes: Carrier, Trane, Lennox, Rheem, Goodman, and older setups still running original equipment from the 70s. We stock common filters and parts locally for Leon Valley customers, including Honeywell and Aprilaire filtration products, so a filter replacement or a minor component swap usually doesn’t require a second visit. If your system runs a Nikro HEPA-compatible setup or you’re considering an Aprilaire media filter upgrade, we can handle that too.
Common HVAC Cleaning Problems We See in Leon Valley Homes
- Pier-and-beam return runs pulling attic dust. Homes along Evers Road and the older streets around Huebner Creek sit on raised foundations, and the unsealed return runs underneath act like a vacuum hose for everything that moves under the house.
- Coils caked with a felt-like mat of lint. On a 1960s ranch in the Forest Oaks area, our technician pulled a blower motor caked with a 1/4-inch felt mat of lint that no register ever showed. The debris had migrated down the lint pathway because the return pan wasn’t sealed to the furnace.
- Oversold “every year” cleanings on homes that don’t need it. If your Leon Valley home had the flex duct replaced recently and you change filters regularly, an annual cleaning may be unnecessary. We’ll tell you honestly when you don’t need the service.
- Per-vent pricing that rushes the small branches. When a company charges by the vent, the incentive is to go fast. The return side and the air handler, where Leon Valley’s pier-and-beam dust actually collects, get skipped. That’s not cleaning, that’s kicking dust around.
Pricing for HVAC Cleaning in Leon Valley, TX
A full HVAC cleaning in Leon Valley, including furnace ducts and AC coils, runs $350 – $650 for a standard home with one system. Add a second system or a large custom home, and you’re looking at $500 – $800. We give you one flat price per system, in writing, before any work starts. No per-vent pricing, no add-ons at the door, no “I found mold” scare tactics. What you’re quoted is what you pay. Estimates are free, and a live person answers the phone when you call (737) 727-2314.
Why do some quotes come in lower? Because those companies typically quote a teaser price per vent on a select few vents, then add charges once the technician is inside. We don’t do that. One system, one price, agreed before we start.

FAQs About HVAC Cleaning in Leon Valley
Most Leon Valley homes built before 1990 genuinely need it at least once, because the pier-and-beam return runs and 50-to-70-year-old ductwork accumulate debris that newer sealed-duct homes don’t. But if your flex duct was replaced within the last few years and you run a clean filter, you may not need it. We’ll inspect your system and tell you honestly before we quote a single dollar. Call (737) 727-2314 if you’re unsure.
You get one written price for the entire system: supply ducts, return ducts, air handler, blower, and AC coil. That price is handed to you before work starts and does not change. No per-vent pricing, no last-minute add-ons. Call (737) 727-2314 for a free quote.
Yes. Every Leon Valley job includes before-and-after photographs of your own ducts, coil, and blower. You’ll see the inside of your return run, the blower wheel, and the coil before we clean them and after. If the coil was caked and now it’s clean, you’ll see it with your own eyes.
Most Leon Valley homes with original 1950s – 1970s ductwork benefit from a full cleaning every 3 to 5 years, not annually. Homes with recently replaced flex duct and consistent filter changes can go longer. A flat “every year” recommendation is usually about sales quotas, not your system. Call (737) 727-2314 for an honest assessment.
No. We don’t promise same-day service because it’s not how quality duct cleaning works. The debris that matters in Leon Valley is in your return side and air handler, and doing that job right takes time. We’ll schedule you for the next available slot and give you a live trackable arrival window through The Relay Standard.
