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 Company in Largo, FL
Air duct cleaning in Largo typically runs $350 – $650 for a whole-home system and takes two to four hours, depending on duct layout and contamination level. The real challenge here isn’t ordinary household dust; it’s the combination of Gulf humidity and airborne silica from Pinellas beaches that coats duct interiors with a sticky, salt-laden film standard vacuums can’t fully strip. Most Largo homes are older ranches and condos with original galvanized or flex ductwork, so our crews use rotary brush systems and negative-air machines to dislodge and extract what the climate deposits inside. Call (361) 326-5060 for a written estimate before any work begins.
Why Largo Homes Are Different
Largo sits on the Pinellas peninsula between the Gulf of Mexico and Tampa Bay, and that geography shapes every job we do. Year-round humidity hovers above 70%, summer thunderstorms drive moisture through attic vents and crawl spaces, and salt-laden sea breezes accelerate corrosion inside metal duct runs. The housing stock tells the rest of the story: single-story block ranches and villas built from the 1950s through the 1980s dominate, many with original galvanized metal or poorly insulated flex duct. In the 55+ mobile home parks off Ulmerton Road, underbelly ductwork runs through sandy soil that wicks moisture upward, rusting out flex ducts and creating mold conditions you’d never find in a slab-on-grade home inland. Condensation at duct joints is routine, and AC systems run nearly constantly, pulling beach sand and pollen deep into the system. We see it in every neighborhood from Oakhurst to Ridgecrest: Largo duct cleaning requires dehumidifying and sanitizing, not just vacuuming.
Our Main Largo Services
Most Largo homeowners call us for one of three jobs, each with its own page and pricing.
Air Duct Cleaning in Largo
We clean the full supply and return network with a Rotobrush rotary brush system that scrubs duct walls while a Nikro negative-air machine pulls dislodged debris out of your home entirely. In Largo, we pay special attention to mold-prone sections where Gulf humidity has settled, and we finish with a sanitizing treatment on galvanized runs that have corroded. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Largo
Dryer Vent Cleaning in Largo
Lint buildup is worse here than inland because humid air keeps fibers clinging to vent walls instead of blowing through. We run a rotary brush from the dryer connection to the exterior cap, then verify airflow with a meter. For condos and villas with long vertical runs through shared walls, we use compressed-air tools and inspect with a camera to confirm the path is clear. Dryer Vent Cleaning in Largo
Duct Sealing in Largo
Original duct joints in Largo’s older homes leak conditioned air into attics and crawl spaces, forcing your AC to run longer and pull in more humidity. We seal accessible joints with mastic and apply aerosol sealant where manual reach is impossible, then pressure-test to verify results. This is often the most cost-effective upgrade for homes with original 1960s or 1970s ductwork. Duct Sealing in Largo
