Fast, Reliable Air Duct Cleaning Across Largo
Air duct cleaning in Largo typically runs $289-$579 for a full residential system, with most jobs completed in a single visit. We’re usually on-site within two hours for calls from the Seminole Boulevard corridor or the neighborhoods west of Belcher Road, and we carry the equipment to handle everything from standard ranch homes to acreage properties with detached workshops.
We’ve been driving these roads since 1984, and we know the difference between a quick turnaround on Rosery Road and the longer haul down unmarked lanes off 142nd Street N or 150th Avenue. Our Air Duct Cleaning team doesn’t guess at drive time or equipment needs. We ask the right questions when you call (844) 685-6342, show up with what the job actually requires, and finish it that day. That’s how we’ve operated for over 42 years.
Why Bellows Air Duct & Vent Co. Is Largo’s Preferred Air Duct Cleaning Company
Largo homeowners call us back because we treat the job like we’re working on our own neighbor’s house. Ray Castillo built this company on the idea that a square deal means one honest price shown before we start, and a guarantee that doesn’t require paperwork to enforce. Our 90-Day Done Right Promise is stamped on every invoice. If something’s not right, we make it right. No forms, no arguing.
We answer our own phones. Twenty-four hours a day, a live person at our office picks up - not a voicemail tree, not an app. That’s mattered to Largo customers, especially in the 55-plus communities off East Bay Drive where folks still prefer to call rather than click.
Our technicians are background-checked and uniformed, and they arrive with Rotobrush and Nikro equipment on board, plus the 10-foot ladders and heavy-duty extenders that acreage properties demand. Most jobs finish in one visit because we don’t send a crew that has to return for parts they should have had.
We’ve earned a strong local reputation across Pinellas County. Homeowners in Largo’s 33770, 33771, 33778, and 33779 ZIP codes know our trucks, and they know the camera inspection footage we show them isn’t stock footage from another job. It’s their ductwork, before and after, every time.
Our Air Duct Cleaning Services in Largo
Residential Duct Cleaning
The concrete block ranch homes that dominate Largo’s 33770 and 33771 ZIPs were built during the 1960s and 1970s Pinellas County retirement boom. Many still run original or early-replacement flex duct in attics that exceed 130°F through summer. That heat degrades the inner liner, and decades of cycling humid, pollen-heavy air leave behind debris you don’t want circulating through your bedrooms. We clean the full supply and return network, camera-inspect every run, and show you what we found. A typical residential duct cleaning in Largo runs $289-$449 for a single-system home.
Commercial Duct Cleaning
Largo’s commercial spaces - medical offices along Missouri Avenue, retail near Largo Mall, and the light industrial shops off Ulmerton Road - face their own buildup patterns. Higher occupancy means more skin cells, paper dust, and synthetic fiber loading in the returns. We scale our Nikro negative-air systems to the building size, work after hours when needed, and provide the documentation property managers require for insurance and lease compliance. Commercial jobs in Largo typically start at $579 and scale with system complexity.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, and in Largo they work harder than almost anywhere else in the country. Running A/C 10-11 months a year means your supplies are under constant pressure. In the western ZIP 33774 near the Intracoastal, salt-laden moisture accelerates corrosion at metal connections. We remove and clean each register, agitate the duct walls with Rotobrush contact cleaning, and extract debris with HEPA-filtered vacuums. Supply-only cleaning in Largo runs $189-$329.
Return Duct Cleaning
Returns pull air back to the handler, and they’re where the heaviest loading collects - pet hair, pollen, cooking oils, and the fine grit that blows in from Gulf beaches. Largo’s return systems in older homes often have undersized or crushed flex runs that choke airflow and strain the blower. We clean the full return path, repair accessible damage, and document restrictions we can’t reach. Return duct cleaning in Largo is typically $169-$299 as a standalone service.
Full System Cleaning
This is what most Largo acreage properties need, and what we recommend for any home that hasn’t been serviced in five years or more. Full system means every supply, every return, the air handler cabinet, the blower assembly, and the coil if accessible. We bring our Abatement Technologies HEPA filtration and our Rotobrush AEQ-500 for the heavy buildup. For the workshop and detached garage systems off 142nd and 150th, we also check cross-contamination paths that can pull wood dust or auto paint fumes into the main house. Full system cleaning in Largo ranges from $449-$749 depending on system count and accessibility.
Video Inspection
Every job we do in Largo includes camera inspection before and after. You see what we see: cracked flex liner, standing water from condensation, rodent nesting, or the microbial growth that thrives in this peninsula humidity. We don’t just tell you the ducts are clean. We show you. Video inspection is included in all full-service packages, or available standalone for $129-$189 if you’re evaluating whether cleaning is needed.

Trusted Brands We Service in Largo
We specify professional-grade equipment because Largo’s conditions demand it. Our trucks carry Rotobrush contact cleaning systems for the heavy debris in aging flex duct, Nikro negative-air machines for whole-house extraction, and Abatement Technologies HEPA filtration to contain what we remove. For air quality upgrades, we install Honeywell electronic air cleaners and Aprilaire media filters - the same brands serious HVAC contractors specify for Florida humidity. We stock parts for these systems locally, so if your Largo home needs a component replacement during cleaning, we don’t leave you waiting.
Common Air Duct Cleaning Problems We See in Largo Homes
- Original 1970s flex duct that’s never been serviced. In the older neighborhoods off Seminole Boulevard, we regularly find boots packed with decades of debris, inner liners cracked from attic heat, and visible microbial growth at the air handler. Homeowners who moved in during the Nixon administration simply never had this on their maintenance radar.
- Crushed or rodent-nested duct in detached workshops. Largo’s acreage properties often have outbuildings with flex duct run through unconditioned attic space. Without regular inspection, squirrels and roof rats turn these runs into nesting material, and the homeowner doesn’t notice until airflow drops or odors migrate to the main house.
- Salt corrosion on metal connections near the Intracoastal. The western 33774 ZIP draws salt-laden moisture through window and door seals, which settles on exposed duct metal and accelerates rust at joints and dampers. We spot this during camera inspection and recommend sealing or replacement before failure.
- Cross-contamination from hobby shops and garages. Woodworkers and auto restorers in Largo’s rural properties often don’t realize their shop’s return duct ties directly into the main house system. Sawdust, paint fumes, and solvent vapors recirculate into bedrooms unless we isolate or filter those runs during cleaning.

What moves you within these ranges? System count, attic accessibility, and contamination level. A single ranch with a crawl-space air handler is straightforward. A two-system acreage home with detached workshop, crushed flex, and rodent damage takes longer and requires more material. We assess this during our free estimate, and we tell you the exact price before we lift a tool. The number on the phone is the number on the invoice. We don’t bait with a low opener and then add charges at the door.
Standing offers for Largo homeowners: $50 off any repair over $250, free second opinion on any written estimate, $89 seasonal tune-up, and a permanent 5% senior and veteran discount. Call (844) 685-6342 for your exact quote.

FAQs - Air Duct Cleaning in Largo
Yes. We carry 10-foot ladders, heavy-duty extenders, and commercial-grade replacement parts for exactly these jobs. Standard crews often don’t stock 2½-inch openers or triple-tension springs, which forces a return trip. We ask about outbuildings when you call, and we arrive prepared to complete the work in one visit. Call (844) 685-6342 to schedule - estimates are free.
Largo’s position on the narrow peninsula, with the Gulf to the west and Tampa Bay to the east, creates a year-round high-humidity corridor that hits homes from both directions simultaneously. This differs from inland Pinellas cities and makes microbial growth inside ductwork one of the most urgent and recurring service drivers here. We see more condensation-related contamination in Largo attics than in Seminole or Pinellas Park, and we address it with thorough drying and, where appropriate, sanitizing treatment. Call (844) 685-6342 for an assessment.
Yes. We specialize in these systems. The concrete block ranches built during the 1960s and 1970s retirement boom often still run original or early-generation flex duct that has degraded from decades of 130°F attic exposure. We clean carefully to avoid further liner damage, document cracks and separations with camera inspection, and can repair or replace accessible sections with galvanized steel boots and modern flex where needed. A typical full cleaning for these homes runs $289-$449. Call (844) 685-6342 to discuss your system.
Yes. Every job includes camera inspection before and after cleaning. You see the actual footage from your ducts - not generic stock video. This is especially valuable in Largo’s older homes, where we often find conditions homeowners didn’t suspect: cracked liners, standing water, or rodent activity in runs that haven’t been opened in 40 years. Standalone video inspection for evaluation purposes runs $129-$189. Call (844) 685-6342 to book.
We remove it with contact agitation and negative-air extraction, then show you the difference on camera. Largo systems cycle enormous volumes of humid, pollen-heavy air nearly year-round, loading ducts far faster than in seasonal climates. For households with allergy sensitivity, we can install Honeywell or Aprilaire filtration upgrades after cleaning to reduce future accumulation. Full system cleaning runs $449-$749 depending on configuration. Call (844) 685-6342 for a free estimate and filtration recommendation.
