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.

AfterAir Duct Cleaning in Largo, FL: What It Costs and What We Find
Air duct cleaning in Largo typically runs $390-$690 for a full system on a single-family home, and $290-$490 for a manufactured home with under-floor belly-pan ductwork. Most jobs take 3-5 hours and include a camera inspection of every supply and return run before and after. You get a written price before we touch a panel, not an estimate that changes once the van is in the driveway.
Largo is not like other Florida cities for ductwork. We work in concrete-block homes built in the 1960s with retrofitted attic flex duct that bakes at 140°F all summer, and in 55+ manufactured home communities off Ulmerton Road where the ducts run in the floor belly-pan. Those are two completely different systems that require two different tool sets. Most crews only carry one. We carry both, and we document everything with photos before we leave. Call (806) 606-6902 for a written quote.
Why Largo Homeowners Choose CleanRun for Duct Cleaning
We started CleanRun in 2013, and since then we’ve documented more than 52,000 homes with written prices and photo records. In Largo, that documentation matters. This area’s marine humidity deposits salt, mold spores, and fine sand inside duct liners in a way you simply do not see ten miles inland. When we opened our camera in a Keene Park home last summer, the liner showed mold colonization six years after the last service. The homeowner had a receipt from another company. What he didn’t have was a photo record proving the previous crew actually cleaned anything. That’s the gap we close.
Every job in Largo receives the same two deliverables: a written price before work starts (Haven Standard Clause 1), and a photographed record of every duct run, before and after, when we finish. No manager approval required for the 365-Day Done Right Promise. It’s in writing on every invoice. If the work isn’t right, we make it right. The crew you meet is background-checked, uniformed, and identified by name before arrival, under Haven Standard Clause 3: Verified Crews. Tomas Reyes leads our Largo operations and reviews every job file personally.
Our Air Duct Cleaning Services in Largo
Residential Duct Cleaning
A typical single-family home in Largo, especially the concrete-block houses from the 1950s through 1970s that dominate neighborhoods like Keene Park and Harbor Hills, has original or first-generation retrofit ductwork. We clean the full system: supply side, return side, plenum, and registers. Our process uses negative-pressure extraction with HEPA filtration so debris doesn’t blow back into your living space. A residential full-system clean in Largo runs $390-$690.
Manufactured Home Duct Cleaning
Largo has one of Pinellas County’s highest concentrations of 55+ manufactured home communities, particularly off Ulmerton Road and East Bay Drive. These homes are different. The ducts run under the floor in a belly-pan, not through an attic. Standard trunk-and-branch equipment can’t reach those runs properly, and standard crews often can’t seal them correctly when they’re done. We access the belly-pan, inspect each run with a camera, clean it, and seal the access point so your HVAC isn’t pulling dirt from the crawlspace. Manufactured home duct cleaning in Largo runs $290-$490 depending on length and configuration.
Supply Duct Cleaning
Supply ducts carry conditioned air from your air handler to your registers. In Largo, these runs collect sand and salt from the coastal air that gets pulled through the system. We clean every supply run from the plenum to the register boot, and we photograph each one. If we find a crimped or sagging section in an attic run, we note it in your service record and can repair it while we’re there. Supply-only cleaning for a smaller Largo home runs $220-$340.
Return Duct Cleaning
Return ducts pull air from your home back to the air handler. They tend to be the dirtiest part of the system because they run at negative pressure and draw unfiltered air from the return grilles. We clean the full return path and replace or clean the filter housing when needed. Return cleaning for a typical Largo home runs $180-$310. If your home has a central return in a hallway, the price is usually at the lower end.
Full System Cleaning
This is the service we recommend for most Largo homes that haven’t been cleaned in five or more years. It includes supply ducts, return ducts, the plenum, the air handler cabinet, the blower motor housing, and all registers. In Largo’s marine-humidity environment, skipping the air handler cabinet means you’re leaving the source of the problem untouched. A full system clean in Largo runs $390-$690, with manufactured homes typically at the lower end and larger single-family homes at the upper end.
Video Inspection
Before we clean anything, we run a camera through your ductwork. You see what we see. If there’s a 3-inch debris build-up at the first elbow, you’ll know before we touch a brush. If there’s mold colonization on the liner, you’ll see the photo. If your 1960s flex duct is brittle and at risk of tearing, we’ll tell you before we start, and we’ll recommend a gentler process. Video inspection is included with every cleaning job at no additional cost. It’s part of the Documented Photo Record you receive when we’re done.

BeforeAfterTrusted Brands We Service in Largo
We work on all major HVAC equipment and duct configurations in the Largo market. Our equipment roster includes Rotobrush, Nikro, and Guardsman systems for negative-pressure extraction, agitation, and HEPA filtration. We also service homes with Honeywell air quality controls and Aprilaire filtration systems. If your home has any of these components, we’re familiar with how they integrate with your ductwork and how to clean them without damaging the system. For Largo’s specific housing stock, which spans 1960s concrete-block homes to manufactured homes with under-floor duct runs, the right tool makes the difference between a real clean and a vacuum noise show.
Common Air Duct Cleaning Problems We See in Largo Homes
- Mold colonization in attic flex duct. Largo attics routinely exceed 140°F in summer, and the Pinellas Peninsula humidity creates a moisture environment you won’t find in inland Florida. Flex-duct liners in these attics grow mold far faster than the industry-standard seven-year cleaning interval assumes. We see it consistently in homes that haven’t been cleaned in five or more years.
- Crimped and sagging attic runs in 1960s concrete-block homes. These homes were built without central air. The ductwork you have was retrofitted decades ago through hot, poorly ventilated attics. Over time, flex ducts sag, crimp, and separate at the joints. It reduces airflow and pulls attic air into your living space.
- Belly-pan duct failure in 55+ manufactured home communities. Off Ulmerton Road and East Bay Drive, under-floor duct runs are prone to moisture intrusion, rodent nesting, and insulation collapse. Crews that only know attic systems can’t properly access or seal these runs. We can.
- Salt and fine sand buildup from coastal air. Largo sits on the Pinellas Peninsula, surrounded by water on three sides. Your HVAC system pulls coastal air through the ductwork, depositing airborne salt, mold spores, and fine sand on the liner surfaces. It’s abrasive and corrosive over time. It also means your ducts need attention sooner than homes in less humid parts of the county.

FAQs - Air Duct Cleaning in Largo
Because the ducts run under the floor in a belly-pan, not through the attic. Standard residential crews arrive with trunk-and-branch equipment built for attic access, and they can’t reach or properly seal under-floor runs. In Largo’s 55+ communities off Ulmerton Road and East Bay Drive, this is the difference between a real clean and a wasted visit. We carry belly-pan access equipment and know how to seal the access points correctly so your HVAC isn’t pulling dirt from the crawlspace. Call (806) 606-6902 for a written quote.
Every 3-5 years, not the 5-7 years you see on generic websites. Largo’s marine humidity and 140°F attic temperatures accelerate mold colonization and liner breakdown in these homes. If your home is in Keene Park or another 1960s-era neighborhood and the ducts are original, you’re overdue. We can run a camera through the system and tell you exactly what’s there before any cleaning happens. The inspection is included.
In most cases, yes, if the smell is coming from the ducts. A musty odor in a manufactured home usually means moisture has entered the belly-pan duct runs and mold or mildew has colonized the liner or insulation. Cleaning the ducts removes the source of the odor, but if there’s an active moisture leak in the belly-pan, that has to be fixed first or the smell will return. We can identify the source with a camera inspection and tell you honestly whether cleaning will solve your issue or whether there’s a bigger problem. Call (806) 606-6902 to book an inspection.
Yes, and it’s not close. Manufactured homes off Ulmerton Road and East Bay Drive run ductwork through under-floor belly-pans, which are far more prone to moisture intrusion, rodent nesting, and insulation collapse than attic runs. Many of these homes are 20-30 years old and have never had their ducts cleaned. The configuration also means standard crews can’t properly service them. If you live in one of these communities, ask any contractor you’re considering whether they work with belly-pan duct systems. If they hesitate, call us.
Yes. Our process uses negative-pressure extraction with HEPA filtration, which means dust and debris are pulled out of the system and trapped, not blown into your living space. We recently cleaned a 1970s Keene Park home while the homeowner’s retired wife stayed in the living room the entire time. No dust, no disruption. If you have severe respiratory issues, we can also run a hospital-grade air scrubber during the job for an additional fee. Tell us when you book, and we’ll plan accordingly. Call (806) 606-6902 for a written estimate.
