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 Morton’s Air Duct Cleaning Is Leon Valley’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our reputation in Leon Valley is built on showing up prepared for what these homes actually contain. The reviews we receive from Leon Valley customers consistently mention two things: the written price they got before we touched anything, and the photo of the clean-up we texted before we left. Our crews know the difference between a 1968 ranch near Loop 410 and a 1982 build closer to Huebner Road, and they know both likely have original ductwork that’s been baking in 140°F attics for decades. We don’t quote over the phone and then change the number on the invoice. The price we write down is the price you pay. Every technician is background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values, which means shoe covers and drop cloths from the moment we walk in, quieter tools during nap hours, and pet-safe product choices where available. A live person answers our phone 24/7, not a voicemail tree.
Air Duct Repair in Leon Valley
Air Duct Repair in Leon Valley almost always involves the original flex-duct or fiberglass duct board installed during the 1960s-1980s build-out along Bandera Road. These systems weren’t designed for forty-plus years of 130-150°F attic heat, and by now the inner liners have delaminated, insulation has collapsed, and sheet-metal connections have corroded through. A typical repair in Leon Valley runs $200-$500 for a partial re-run or connection rebuild, while full duct replacement in a single-story ranch can reach $2,500-$4,500 depending on linear footage and access. We always camera-inspect before cutting anything, because aggressive work on friable fiberglass duct board without proper containment spreads fibers instead of fixing the problem.
Collapsed Flex-Duct Sections
We find these on most jobs in Leon Valley. The plastic inner liner separates from the insulation blanket, the duct sags or crushes, and airflow drops to a trickle in the back bedrooms. Our crew pulls the damaged run, measures on-site, and installs new flex-duct with mechanical connections and proper support straps. We seal everything with mastic, not tape that’ll fail in the next heat wave.
Duct Board Deterioration
Original fiberglass duct board from the late 1960s and 1970s subdivisions turns friable and sheds particles directly into supply air. We don’t brush this blindly. We set up negative pressure containment with HEPA filtration first, then use controlled agitation and extraction to remove loose material without spreading it through your house. Sometimes the board is too far gone, and we’ll tell you straight if replacement makes more sense than repair.
Ductwork Cleaning in Leon Valley
Ductwork Cleaning in Leon Valley requires a different protocol than in newer construction because of the concentrated vintage of housing stock here. Nearly every home in the city was built between the early 1960s and mid-1980s, which means original attic-routed flex duct and fiberglass duct board that have been thermally stressed past their design life. A standard cleaning in Leon Valley runs $350-$650 for a full residential system, but we won’t sell you a cleaning if camera inspection shows the duct material itself is failing, because knocking loose delaminated liner makes the air quality worse, not better. Our process starts with video inspection, then negative-pressure HEPA containment, agitation with Rotobrush or Nikro tools matched to your duct type, and source removal at the air handler including blower wheel and housing cleaning.
Whole-System Source Removal
We don’t just vacuum the registers. We pull the blower motor, clean the wheel and housing where the worst buildup hides, and run brushes and whips through every supply and return branch. For Leon Valley’s older systems, we pay special attention to the return chase, where decades of skin flakes, pet dander, and Mountain Cedar pollen have accumulated in the porous fiberglass.
Post-Clean Sealing and Filter Upgrade
After cleaning, we seal registers and returns with magnetic covers during the off-season, and we always check that your filter is properly matched to a MERV rating your system can handle. The December-February Mountain Cedar pollen in this region is among the highest airborne pollen events in the United States, and a fresh clean duct system gets re-contaminated fast if the intake side isn’t protected.
Trusted Brands We Service in Leon Valley
Our trucks carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, not the rental-grade gear you can pick up at a big-box store. We stock flex-duct, duct board, and mechanical connectors sized for the 6-inch and 8-inch runs common in Leon Valley’s ranch homes, which means most repairs don’t require a second trip. For filtration upgrades, we work with Honeywell and Aprilaire media cabinets and can source Guardsman antimicrobial treatments where appropriate. Parts availability matters when you’re trying to get a home sealed up before cedar season hits, and our San Antonio warehouse keeps Leon Valley jobs moving without long waits.
Common Air Duct Cleaning Problems We See in Leon Valley Homes
- Delaminated flex-duct liners from decades of attic heat. The plastic inner layer separates from the wire helix and insulation blanket, creating a flapping obstruction that sheds particles and blocks airflow to back rooms. We camera-locate the damage before deciding whether cleaning, repair, or replacement is the right call.
- Friable fiberglass duct board shedding gray fibers into supply air. This is concentrated in Leon Valley’s 1960s-1970s builds in a way we rarely see in newer San Antonio neighborhoods just across the city limits. The material turns to powder after repeated thermal cycling, and standard brushing without containment makes it worse.
- Corroded sheet-metal connections at the plenum and trunk lines. Galvanized steel connections in these slab-on-grade homes have been exposed to condensation and attic temperature swings for forty to sixty years. We find gaps and rust-through that leak conditioned air into the attic and pull hot, dusty attic air back into the system.
- Mountain Cedar pollen loading in return systems. The Ashe juniper pollen season from December through February pushes enormous allergen volumes through Leon Valley HVAC systems. Returns in these older homes often lack proper filtration sealing, so pollen coats the blower wheel and duct walls year after year.
Pricing for Air Duct Cleaning in Leon Valley, TX
Whole-home residential duct cleaning in Leon Valley typically costs $350-$650, depending on system size, accessibility, and whether we find damaged duct material that needs repair before cleaning can proceed safely. Commercial systems or properties with outbuildings and long driveways may run higher based on linear footage and travel time. We do not price per vent or offer teaser coupon rates that balloon once we’re on site. You get one flat price per system, agreed in writing before any work starts. Factors that affect your specific quote include: whether your home has original flex duct or duct board, how many air handler components need cleaning, and whether video inspection reveals damage that should be repaired first. Estimates are free, and we’ll walk you through the camera footage so you see what we see. Call (323) 918-4345 to schedule.

FAQs About Air Duct Cleaning in Leon Valley
Every three to five years is realistic for Leon Valley’s 1960s-1980s housing stock, though homes with pets, multiple residents, or significant Mountain Cedar sensitivity may need attention every two to three years. The combination of aging duct materials and San Antonio’s intense pollen loads means these systems accumulate debris faster than newer construction with intact ductwork. Call (323) 918-4345 and we’ll camera-inspect to give you a specific interval for your home.
Gray fibers are almost always deteriorating fiberglass duct board or delaminated flex-duct liner, both endemic to Leon Valley’s single-vintage housing stock. The material has been thermally cycled past its design life and is now friable, breaking down with every HVAC cycle. Cleaning without repair or replacement can make shedding worse by disturbing the fragile surface. We camera-inspect first to determine whether source removal, containment, or full replacement is the appropriate fix.
Yes, the City of Leon Valley funds a residential duct cleaning reimbursement program that most surrounding San Antonio neighborhoods do not offer. The program is designed to address the concentrated aging duct inventory across the city’s 1960s-1980s housing stock. We provide the documentation and itemized invoicing required for reimbursement claims, and we can explain the current program requirements when you call for your estimate.
Properties with shop buildings, guest houses, or long unpaved drives require additional linear footage pricing and sometimes portable power or extended hose runs. Dust loading from unpaved roads and open land is also heavier, which can shorten the effective cleaning interval. We quote these jobs specifically based on total system footage and access conditions, not with a flat rate that changes on arrival.
It helps significantly if the cleaning is followed by proper register sealing and a correctly matched filter upgrade. The Mountain Cedar pollen season from December through February is severe in this region, and a clean duct system removes the accumulated reservoir of past seasons’ pollen, dust, and biological material. Without sealing and filtration improvements, re-contamination happens within one season. We address all three steps, not just the cleaning itself.
