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 Lewisville’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our reputation in Lewisville is built on showing up, protecting your floors, and telling you the truth about your ducts even when the news isn’t simple. Our technicians are 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.
Lewisville homeowners call us back because we provide a written price before any work starts, every single time. No surprises on the invoice. Our Air Duct Cleaning team also leaves photo proof of the clean-up, so you can see the difference at your registers. A live person answers our phone 24/7, not a voicemail tree, because we know duct questions don’t always come up during business hours.
We coordinate scheduling through our Seattle office, but our crews serve Lewisville locally and understand the specific challenges of lake-adjacent ductwork. That local knowledge matters when we’re crawling an attic off Lake Vista or inspecting a system in Old Orchard where the humidity profile is completely different from a home across town.
Ductwork Cleaning in Lewisville
Ductwork Cleaning in Lewisville is rarely a simple vacuum job because the city’s housing stock tells a complicated story. The bulk of Lewisville’s homes were built during the 1980s-1990s suburban boom with flexible ductwork that’s now 30-40 years old. That original flex duct is often sagging between joists, crushed at tight bends, or disconnected at wye fittings in the attic. A straight cleaning without addressing these structural failures leaves debris trapped in low spots and conditioned air leaking into your attic year-round.
Our process starts with negative pressure HEPA filtration, not a shop vac. We use Rotobrush and Nikro agitation tools to dislodge buildup from duct walls, then extract it under contained suction so nothing resetstles in your living space. For Lewisville’s older homes, we typically find that sealing disconnected runs with mastic and foil tape, and sometimes replacing crushed sections, is what actually solves the problem a cleaning alone cannot.
What We Find in 1980s-1990s Lewisville Homes
On a 1987 build off Lake Vista, our tech pulled a camera inspection on the original flex trunk and found two runs crushed flat behind the air handler, one disconnected at a wye in the attic, and a fuzzy gray layer on the inner liner that wiped off as mold. We ran negative pressure with HEPA filtration, used agitation tools on the supply and return ducts, sealed the disconnected run with mastic and foil tape, and swapped the filter to a MERV 11 so the homeowner could see the difference at the registers.
Castle Hills and Newer Construction
Castle Hills presents a different challenge. The phased development from the 2000s-2010s means fine construction dust from ongoing nearby building migrates past standard filters into supply lines and registers. A cleaning that doesn’t check the blower motor and air handler leaves the source of the dust load untouched, so the problem returns within months.
Air Duct Inspection in Lewisville
Air Duct Inspection in Lewisville is the step most homeowners skip, and it’s the step that determines whether a cleaning will actually solve your problem or just move debris around. We use video inspection equipment to see inside your ductwork before we quote any work, because Lewisville’s lake-adjacent humidity and aging flex-duct inventory create conditions that change what “cleaning” means from one house to the next.
The inspection typically takes 45-60 minutes and costs $150-$250 as a standalone service, though we credit that amount toward any cleaning work we perform. We’ll show you the footage. If your flex-duct liner is intact with surface mold, we can clean and treat it. If the liner is deteriorating or the duct is crushed beyond recovery, we’ll tell you that too, so you’re not paying for a temporary fix on a failing system.
When to Request an Inspection First
Schedule an inspection before cleaning if your home is in Old Orchard, Lake Vista, or another shoreline neighborhood where lake humidity runs high, or if your house was built between 1980 and 1999 and you’ve never had the ductwork evaluated. Visible mold at registers, uneven airflow between rooms, or a musty smell when the AC kicks on are all signals that the ducts need eyes inside before tools go in.
What the Camera Reveals
Our video system records in high resolution, and we save the footage for you to review. In Lewisville, we commonly document sagging flex duct creating debris-collecting valleys, disconnected runs blowing conditioned air into attics, and microbial growth on inner liners that a standard cleaning would aerosolize rather than remove. Knowing what we’re dealing with lets us quote accurately and perform the right work the first time.
Trusted Brands We Service in Lewisville
Morton’s technicians work with professional-grade equipment from Nikro, Honeywell, and Aprilaire, not rental-shop gear that loses suction halfway through a job. We stock filters, UV treatment components, and sealing materials specific to the systems common in Lewisville’s housing stock, which means faster turnaround and fewer return visits. Our Nikro negative air machines and Honeywell media filters are matched to the MERV ratings and airflow requirements of older flex-duct systems, so we don’t create new problems while solving old ones. When we recommend a product or replacement part, it’s because we’ve installed it in Lewisville homes like yours and watched it perform through multiple seasons.
Common Air Duct Cleaning Problems We See in Lewisville Homes
- Lake humidity mold in shoreline neighborhoods. Technicians working neighborhoods bordering Lewisville Lake, Old Orchard, Lake Vista, and the older shoreline streets, routinely find visible mold on flex-duct inner liners even in homes that have never flooded. The persistent elevated humidity from the lake creates a microclimate that inland DFW suburbs simply don’t share, and skipping HEPA-equipped negative pressure means that microbial layer gets disturbed but not removed.
- Crushed and disconnected original flex duct. The 1980s-1990s tract homes that make up much of Lewisville’s inventory use flex duct that degrades over decades. Sagging runs collect debris in valleys where vacuum tools can’t reach, and disconnected wyes leak conditioned air into attics while drawing in insulation particles and rodent droppings. A cleaning without sealing is half a job.
- Construction dust in Castle Hills and newer phases. Fine particulate from ongoing development migrates through standard filters and deposits in supply ducts. Homeowners notice gray film on registers within weeks of cleaning because the blower motor and air handler, the actual source, were never addressed.
- Shortened cleaning-to-replacement windows near the lake. Lewisville’s lake-adjacent humidity doesn’t just create mold, it accelerates liner deterioration. A flex duct that might last five more years in Frisco or Allen often needs replacement in two or three near Lewisville Lake, because the moist environment breaks down the fiberglass and mylar layers faster.
Pricing for Air Duct Cleaning in Lewisville, WA
A typical residential ductwork cleaning in Lewisville runs $350-$650 for a full system, depending on home size, duct accessibility, and whether we find disconnected or crushed runs that need sealing or section replacement. Air duct inspection as a standalone service is $150-$250, credited toward cleaning if you proceed. Dryer vent cleaning, often booked together, adds $120-$180.
What moves the price: homes with multiple HVAC systems, ductwork in cramped crawlspaces rather than attics, and the extent of sealing or repair needed on 1980s-1990s flex duct. We don’t quote per-vent pricing, which is the industry’s favorite bait-and-switch tactic. One flat price per system, agreed in writing before we start. Every estimate is free, and we’ll show you the video inspection so you understand exactly what we’re quoting and why.
Call (323) 918-4345 for your exact number. No pressure, no teaser rates, just the actual price for your actual house.

FAQs About Air Duct Cleaning in Lewisville
The lake itself is the source. Lewisville’s position directly adjacent to Lewisville Lake creates a persistent localized humidity that keeps relative humidity measurably higher than in fully inland DFW suburbs like Frisco or Allen. That moisture condenses inside supply ducts during the long cooling season, typically May through October, and the dark interior of flex duct provides exactly the environment mold needs. We’ve found visible growth in shoreline homes that have never had a water intrusion event of any kind. Call (323) 918-4345 and we’ll inspect with a camera to confirm whether you’re dealing with surface mold that can be cleaned, or liner deterioration that requires replacement.
The camera inspection tells the story. If the mylar liner is intact with surface mold or debris, we can clean and treat it successfully. If the liner is flaking, torn, or the fiberglass insulation layer is exposed, cleaning will damage it further and replacement is the honest recommendation. We show you the footage and explain what we’re seeing, so the decision is yours with real information. The lake humidity near Old Orchard and Lake Vista does shorten the replacement timeline compared with inland cities, so a duct that was borderline two years ago may have crossed the line now. Call (323) 918-4345 for a video inspection and we’ll give you a straight answer.
Inspection is diagnosis; cleaning is treatment. An air duct inspection uses video equipment to document the condition inside your ducts, identify crushed or disconnected runs, and determine whether mold is present and whether the liner can handle cleaning. Ductwork cleaning is the physical work of dislodging debris, extracting it with HEPA-contained negative pressure, sealing leaks, and treating microbial growth where found. In Lewisville’s older housing stock, we strongly recommend inspection first because the original flex duct often has structural issues that cleaning alone won’t solve. The $150-$250 inspection fee is credited toward cleaning if you proceed.
The dust source is usually the blower motor and air handler, not the ducts themselves. Castle Hills and other 2000s-2010s construction areas have fine construction dust from ongoing phased development that migrates past standard filters. If your previous cleaning addressed only the duct trunk and registers without opening the air handler cabinet to clean the blower wheel and evaporator coil, the dust factory is still running every time the fan kicks on. Our full system cleaning includes the air handler components, and we upgrade filtration to MERV 11 or better where the system can handle it. Call (323) 918-4345 and we’ll show you exactly what’s happening inside your unit.
Not necessarily more often, but earlier intervention matters more here. The elevated humidity near Lewisville Lake accelerates mold growth once conditions inside the duct reach the threshold, and it degrades flex-duct liners faster than the drier climate in Frisco or Allen. Where a homeowner in Allen might notice gradual dust buildup over seven to ten years, a Lewisville Lake-area homeowner might see register mold or musty airflow in five to seven years, not because the ducts are dirtier faster, but because the moisture creates active biological growth that changes the problem from “dusty” to “contaminated.” We recommend inspection at the first sign of musty smell or visible register staining, rather than waiting for a scheduled maintenance cycle. Call (323) 918-4345 and we’ll assess where your system stands.
