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, FL typically runs $350 – $800 for a standard single-system home, and most jobs are completed in 3 – 5 hours with zero mess left behind. Largo’s coastal humidity and older housing stock mean ducts here collect a specific mix of sand, salt air residue, and HVAC condensation buildup that inland homes rarely see. Cardinal Air Duct Cleaning handles it with negative-pressure extraction, meaning loosened debris goes straight into a Nikro HEPA vacuum rather than back into your living room. Call (737) 727-2314 for a written, flat-rate quote before any work starts.
Why Largo Homes Are Different
Largo sits a few miles inland from the Gulf, but the air’s salt content tells a different story. Homes in neighborhoods like Harbor Bluffs and Imperial Point pull in coastal air that carries fine salt particles. Those particles settle in ductwork, cling to moisture from AC condensation, and form a gritty film that reduces airflow and feeds mildew. Most Largo homes also run air conditioning ten months a year, so the system never gets a true off-season to dry out.
The housing stock adds another layer. Largo has thousands of homes built between the 1960s and 1980s in communities like Lake Avenue Estates and Anona. Many still run original rigid metal ducts that corrode at the seams. We regularly find duct tape from decades-old renovations, now dried and peeling, leaking conditioned air into attics that hit 130 degrees in summer. That’s why a Largo duct cleaning usually includes sealing visible seam gaps, not just vacuuming. Newer construction near the Largo Mall and along Ulmerton Road tends to use flex duct, which has its own issue: sagging runs that trap debris at low points.
Our Main Largo Services
Most Largo homeowners call us for one of three things: dryer vent cleaning, full air duct cleaning, or HVAC cleaning. Each has its own dedicated Largo page with pricing and service details.
Dryer Vent Cleaning in Largo
Dryer vents in Largo clog faster than you might expect because our humidity keeps lint damp and sticky. Add sand from beach trips and pet hair from Largo’s many dog-friendly neighborhoods, and a vent can choke within two years. We run a Rotobrush rotary system and a Nikro vacuum through the full vent run, from dryer to exterior cap. We also check the termination point, which in many Largo homes is a roof cap that birds and wasps like to claim. Full details are on our Dryer Vent Cleaning in Largo page.
Air Duct Cleaning in Largo
Full air duct cleaning in Largo starts with an inspection of your supply and return plenums, then moves to source removal using our Abatement Technologies containment setup and Rotobrush agitation system. The negative-pressure extraction keeps everything moving into the Nikro HEPA vacuum. Because Largo homes battle salt air and high humidity, we also evaluate duct insulation and recommend sealing options where moisture intrusion is evident. See the full breakdown on our Air Duct Cleaning in Largo page.
HVAC Cleaning in Largo
HVAC cleaning goes beyond the ducts. We clean the blower motor housing, evaporator coil, condensate pan, and plenum box. In Largo, evaporator coils develop a slimy biofilm faster than in drier climates, which means the AC works harder and runs longer to hit your thermostat setting. Removing that buildup often drops energy use immediately. We also treat the condensate line to prevent the algae clogs that plague Largo systems in August.
