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.

Why Cardinal Air Duct Cleaning Is Schertz’s Preferred HVAC Cleaning Company
Homeowners across Schertz call us because we do one thing and we do it with total transparency. We don’t charge per vent, we don’t invent problems during the inspection, and we hand you a written price before a single tool comes off the truck. That price doesn’t change at the door. Our HVAC Cleaning team runs Rotobrush agitation systems paired with Nikro HEPA filtration units, so the debris we loosen goes into a sealed vacuum, not back into your living room.
The 365-Day Done Right Promise covers every Schertz job without exception. If something isn’t right within a full year, we return and correct it at no charge. That’s the longest satisfaction window in the trade, and it applies to AC vent cleaning, furnace duct cleaning, coil treatment, everything. We’re part of the Relay Home Co. family, founded 2005, and every location operates under the Relay Standard: a live trackable arrival window, before-and-after photo documentation, and a digital invoice you can pay from your phone. No voicemail loops. No vague four-hour windows. You’ll know your technician’s name before they arrive, and they’ll be background-checked and in uniform.
Our crew was called out to a two-story in the Buffalo Crossing neighborhood where a homeowner complained of dust and weak airflow upstairs. After a camera inspection, we found the supply and return ducts lined with construction debris and drywall dust, plus a blower motor caked in lint. We set up negative pressure with HEPA filtration, used agitation tools to break the debris loose, and sealed the system before cleaning. A before-and-after photo set showed the homeowner exactly what came out, and airflow at the registers improved noticeably. That’s the job, done plainly.
AC Vent Cleaning in Schertz
AC vent cleaning in Schertz is the process of removing accumulated dust, pet hair, and other buildup from your supply vents, return grilles, and the duct runs that connect them to your air handler. In Schertz, where the cooling season runs from March through October, your system moves a lot of air through those vents, and every cycle pulls in whatever is floating around your house: dust from I-35 corridor traffic, pollen from the live oaks around Universal City, lint from the dryer, pet dander. Over time, that layer builds and restricts airflow. A typical AC vent cleaning in Schertz runs $425 to $565 for a full system, including all vents, the return, and the blower compartment.
Signs Your Vents Need Attention
You’ll notice dust streaks around supply registers even when they’re closed. Some rooms will feel warmer than others on the same thermostat setting. You might hear a faint whistle from a register that never used to whistle, which usually means airflow is being choked somewhere in the run. These are all reasons to call (737) 727-2314 for an inspection.
What’s Included
We remove each vent cover, agitate the inside of the duct run with a Rotobrush system, and pull everything out under negative pressure with a HEPA-filtered Nikro vacuum. The process includes the supply side, the return side, and the accessible portion of the air handler. You get a before-and-after photo set showing what we removed.
Furnace Duct Cleaning in Schertz
Furnace duct cleaning in Schertz means cleaning the full ductwork system that your furnace and AC share, including the return plenum, supply trunk, and branch lines. Even though Schertz winters are short, the furnace still runs enough from November through February to pull fine dust through the heat exchanger and into the ductwork, and whatever settles there stays there all summer, cycling through your home again. A standard furnace duct cleaning in Schertz runs $450 to $690, depending on system size and the condition of the ductwork, and the price is written down before we begin.
Combined Systems, One Visit
Most Schertz homes use a single air handler for both heating and cooling, so cleaning the furnace ducts and the AC vents is the same job. We do both in one visit, not two separate charges. If your home in the older part of Schertz near FM 78 has legacy metal trunks, we treat those differently than the builder-grade flex duct you’ll find in newer neighborhoods like Sedona Ranch. The method matches the material, and the flat price reflects the system, not the square footage.
Heat Exchanger Cleaning
Looking for heat exchanger cleaning in Schertz? This is part of what we do when the blower and plenum are accessible. You get the same flat price, the same before-and-after photos, and the same 365-Day Done Right Promise. Call (737) 727-2314 and we’ll walk you through what’s included, before we schedule anything.
Trusted Brands We Service in Schertz
Our technicians work on systems from every major manufacturer you’ll find in Schertz homes, from Carrier and Trane to Goodman, Lennox, and Rheem. We stock common filters, coil treatments, and disposable components locally, which means faster turnaround when your cleaning reveals a wear item that needs attention. We also carry Guardsman filtration products for homeowners who want an upgrade after the ducts are clean. If you’ve got a system we didn’t list by name, call us: if it moves air through ducts, we clean it, and the same flat-price rule applies no matter the brand.
Common HVAC Cleaning Problems We See in Schertz Homes
- Construction debris in newer builds. Homes built in Schertz subdivisions like Sycamore Ranch and Buffalo Crossing within the last few years often have drywall dust, sawdust, and sometimes even fast-food wrappers sealed inside the ductwork from the construction phase. A camera inspection finds it; a proper cleaning removes it.
- Builder-grade flex duct that sags or kinks. Many newer Schertz homes use flexible ductwork that can develop low spots or kinks, especially in attic runs above the hot Texas sun. Debris pools in those low spots, and airflow suffers. Our agitation process reaches those runs without tearing them.
- Clogged blower motors from constant AC use. Schertz’s cooling season is long, and the blower runs hard for most of the year. Lint, dust, and pet hair build up on the blower wheel, reducing its efficiency. We clean the blower as a standard part of every job, not as an upsell.
- Fine dust from the I-35 corridor. Homes near the interstate, especially around the Schertz Parkway and FM 3009 areas, see more airborne particulate matter than homes further east toward Cibolo. That fine dust works its way into return ducts and onto evaporator coils more quickly, which means a system cleaning makes a bigger difference in air quality for those properties.

FAQs About HVAC Cleaning in Schertz
Every three to five years for most Schertz homes, assuming the system is running normally and you change filters regularly. Homes near I-35 or with multiple pets may benefit from a two-year cycle. If you’re seeing visible dust on registers or noticing weak airflow, don’t wait for a calendar to tell you it’s time; call (737) 727-2314 and we’ll help you figure out if cleaning is actually needed, or if a filter change and coil treatment would be smarter. An honest answer is always free.
Flat price per system, always. Per-vent pricing is how duct cleaners justify rushing through each register and skipping the air handler and blower motor. We quote the whole system, write the number down before work begins, and it doesn’t change at the door. For a typical Schertz home, that means $425 to $690 for a complete cleaning.
We inspect the system with a camera first, then clean the supply and return ducts, the evaporator coil, and the blower motor using Rotobrush agitation and Nikro HEPA filtration. Debris is extracted under negative pressure, so it goes into the vacuum, not your living space. You get before-and-after photos of your own ducts, not stock images. The 365-Day Done Right Promise covers the whole job.
Yes. Most Schertz homes have a single air handler serving both heating and cooling, which means the ductwork is shared. One cleaning covers both functions, and it’s one flat price. We won’t split it into two invoices or pretend the furnace side is a separate job.
We don’t promise same-day service, and we’d warn you away from any company that does. A proper HVAC cleaning starts with a camera inspection, and rushing that step means missed debris in hidden flex runs or behind the air handler. We schedule your cleaning at a time that works for you, and you get a live trackable arrival window under The Relay Standard. Call (737) 727-2314 and we’ll find the soonest appropriate slot together.
