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.

AfterFast, Reliable Air Duct Cleaning Across Largo
Air duct cleaning in Largo typically runs $350-$650 for a whole-home residential system, and every job starts with a written price before we touch anything. We’re the Air Duct Cleaning crew families call when they want the job done right the first time, with photo proof before we leave.
We’ve been serving Largo and the mid-Pinellas Peninsula since 2005, dispatching from our South Florida office with crews who know the local housing stock cold. From the 1960s concrete-block ranches off Ridge Road to the manufactured-home communities along Ulmerton, we understand what ten-to-eleven months of annual AC cycling does to ductwork in this humidity. You get background-checked, uniformed technicians who wear shoe covers, lay drop cloths, and keep voices low during nap hours. Call (323) 918-4345 and a live person answers, 24/7.
Why Morton’s Air Duct Cleaning Is Largo’s Preferred Air Duct Cleaning Company
Largo families choose us because we treat their homes like we treat our own. The Cedarwell Care Promise isn’t a slogan on a van, it’s a system: written price upfront, shoe covers and drop cloths on every visit, quiet tools when kids are sleeping, and a photo of the clean-up before the crew leaves so you see what was done.
Our technicians are background-checked and trained on the equipment that actually works here, Rotobrush agitation systems and Nikro HEPA-filtered negative-air machines, not rental shop vacs with a long hose. We’ve handled the specific failure modes Largo’s climate creates: delaminated flex-duct liners in 1970s CBS attics, belly-board moisture intrusion in manufactured homes, and the persistent musty recontamination that happens when crews fog a sanitiser instead of removing the source.
Scheduling runs through our Miami office, but the crew that arrives at your door knows Largo’s neighborhoods and building types. No out-of-town franchise techs guessing at Pinellas County conditions.
Air Duct Repair in Largo
Air Duct Repair in Largo usually means fixing what the local climate and housing age have damaged, not just patching a disconnected joint. A typical repair here runs $200-$450 depending on access and material, with a written quote before any cutting starts.
In Largo’s 1960s-70s concrete-block homes, we regularly find original flex ductwork routed through unconditioned attics where summer temperatures exceed 140°F. That heat collapses inner liners, crushes runs against trusses, and creates debris traps that no amount of vacuuming from the register end will clear. Our crew opens the plenum, inspects with a camera, and replaces damaged sections with properly sized, insulated flex or hard duct where appropriate.
Crushed and Delaminated Flex Duct
The inner liner of 1980s-vintage flex duct separates from the insulation jacket, creating a pocket that holds moisture and biological growth. We cut out the damaged run, install new R-8 insulated flex with proper support straps, and seal all connections with mastic, not tape that will fail in the attic heat.
Mobile and Manufactured-Home Belly-Board Systems
Under-floor ductwork in Largo’s manufactured-home communities uses a belly-board membrane that tears easily and wicks ground moisture. We repair torn sections, seal plenum connections, and recommend moisture barriers where the soil pad underneath has shifted or settled.
Ductwork Cleaning in Largo
Ductwork Cleaning in Largo is source-removal work, not a scented fog pumped through your registers. A full residential system clean runs $350-$650, commercial systems start around $800 and scale with square footage and access complexity.
We use Rotobrush contact agitation with simultaneous HEPA-filtered negative air collection, so debris is loosened and removed in the same pass, not pushed deeper into the system. Every supply and return register comes off. The plenum gets opened and vacuumed. We photograph the before and after so you see the difference, not just smell it.
What Source-Removal Actually Means
We physically remove the contamination: contact brushing of duct walls, vacuum extraction at 2,000+ CFM, and hand-cleaning of boots and register grilles. Fogging a chemical sanitiser without removing the wet debris first is like spraying deodorant on a moldy sponge. The smell comes back in two weeks.
Video Inspection Included
Before we quote and after we finish, we run a camera. In Largo’s older stock, we often find damage the homeowner didn’t know existed, a crushed run to a back bedroom, a disconnected return in the attic, a belly-board tear wicking water. You see it on screen. Then you decide what to fix.
Trusted Brands We Service in Largo
Our trucks carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, brands built for daily commercial use, not weekend rental. Rotobrush contact agitation systems break bonded debris loose from duct walls. Nikro HEPA-filtered negative air machines maintain containment so nothing resetstles in your living room. Abatement Technologies supplies the containment and filtration accessories we use on larger Largo commercial jobs. We stock common flex-duct sizes, plenum fittings, and sealants locally, so repairs don’t wait on a parts run to Tampa.
Common Air Duct Cleaning Problems We See in Largo Homes
- Delaminated flex-duct liners in 1970s CBS attics. The inner polyethylene layer separates from the wire helix and insulation, creating a debris trap that restricts airflow and harbors biological growth. Attic heat above 140°F accelerates this failure, and we see it far more often in Largo’s inland grid than in coastal Clearwater condos.
- Musty recontamination from moisture intrusion. Largo’s mid-peninsula position means salt-laden humidity from Tampa Bay and the Gulf infiltrates whenever duct seals fail or doors open frequently. That moisture feeds mold colonies that survive light vacuuming and return within weeks.
- Crushed supply runs in retrofitted central AC. Many Largo concrete-block homes got ductwork added in the 1980s with tight attic routing. Over decades, truss compression or installer shortcuts collapse the duct, choking airflow to specific rooms while the air handler works harder.
- Belly-board tears in manufactured-home communities. The under-floor membrane in Largo’s mobile-home parks tears on ground contact, wicking moisture and introducing soil contaminants directly into the return stream. Standard attic duct cleaning methods miss this entirely.
Pricing for Air Duct Cleaning in Largo, FL
Whole-home residential duct cleaning in Largo runs $350-$650 for a typical single-system home up to about 2,500 square feet. Manufactured homes with belly-board systems fall in the same range, though access complexity can push larger double-wides toward the upper end. Commercial systems start around $800 and scale with HVAC tonnage, duct linear footage, and whether we need after-hours scheduling.
What moves the number: number of supply and return registers, presence of a second air handler, accessibility of the plenum, and whether we find damage requiring repair. We do not quote per-vent pricing. One flat price per system, agreed in writing before work starts. Every estimate is free, and we explain exactly what that price covers before you decide.

FAQs About Air Duct Cleaning in Largo
Largo sits mid-peninsula between Tampa Bay and the Gulf, drawing ambient moisture from both directions, while Clearwater’s coastal exposure and Seminole’s slightly inland position create different humidity patterns. That dual moisture source, combined with ten-to-eleven months of continuous AC circulation, keeps biological growth fed year-round instead of letting it go dormant. Source-removal cleaning that extracts the wet debris, not fogging that masks it, is the only lasting fix. Call (323) 918-4345 for a camera inspection and exact quote.
Yes, and we use different methods than for standard attic flex duct. Belly-board systems run under the floor, vulnerable to ground moisture and tears in the membrane. We inspect with a borescope, repair accessible tears, and use controlled negative pressure with sealed register boots to extract debris without collapsing the lightweight duct. Photo documentation shows you what we found and what we removed. Estimates are free.
No, if the cleaning was done properly. Fogging or spraying a sanitiser through registers without opening the plenum or removing wet debris kills surface microbes temporarily and leaves the food source intact. In Largo’s humidity, regrowth typically appears within two to four weeks. We don’t upsell fogging because source removal, HEPA-filtered extraction, and proper sealing of the system afterward, is what actually solves the problem. The 365-Day Done Right Promise covers our work, not a chemical warranty.
Every three to five years for most Largo homes, but sooner if you have pets that shed, recent renovation dust, or occupants with respiratory sensitivity. Homes with original 1970s flex duct or belly-board systems may need inspection every two years due to the local climate’s accelerated degradation. We don’t push unnecessary cleans; call (323) 918-4345 and we’ll tell you honestly whether you’re due.
The EPA notes that indoor air can hold two to five times the concentration of certain pollutants as outdoor air, and in humid climates with tight construction, that ratio can rise. Largo’s near-constant AC operation means occupants spend more time breathing recirculated indoor air than in climates with natural ventilation seasons. Clean ductwork reduces the particulate load being recirculated; it’s one component of maintaining healthier indoor air, alongside filtration and humidity control. For a specific assessment of your Largo home’s system, call (323) 918-4345 for a free estimate.
