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 Longwood, FL
Air duct cleaning in Longwood, FL typically costs $350 – $650 for a whole-home system and should be scheduled every 3 – 5 years due to the region’s constant humidity and heavy oak canopy. We’re Hollis Air Duct Cleaning, and we’ve built our work around what actually happens inside Longwood homes: ducts that never dry out, original flex ductwork sagging with debris, and fiberglass insulation breaking down in the historic district. Our crews arrive uniformed, price every job in writing before touching equipment, and back it with the 365-Day Done Right Promise. Call (361) 326-5060 for a free estimate.
Why Longwood Homes Are Different
Longwood sits under one of the densest oak canopies in Seminole County, and that changes everything about what’s inside your ducts. The pollen, leaf litter, and organic debris from live oaks and pines don’t just settle on your roof; they get drawn into your HVAC system through soffit vents and gaps in the return plenum. Once inside, they stick to damp duct walls and start breaking down.
Here’s the real problem: Longwood’s air conditioning runs 10 – 11 months a year. That constant cooling keeps humidity inside the ductwork at levels where mold and mildew colonize fast. In drier inland Florida cities, ducts get a seasonal dry-out. In Longwood, they rarely do.
The housing stock makes this worse. The 1970s – 1980s ranch homes near the historic district often have original flexible ductwork with deteriorating fiberglass insulation that’s been wet-cycling for decades. We’ve opened systems in neighborhoods like Sabal Point where the insulation wrapping has turned black with biological growth. The 1990s – 2000s subdivisions fare better structurally, but their rigid metal trunks with flex runs still accumulate fine debris because the blower runs almost daily. When we inspect a Longwood system, we’re not just looking for dust; we’re mapping moisture damage and organic buildup that shorter-season markets simply don’t see.
Our Main Longwood Services
Most Longwood homeowners call us for one of three jobs. Each has its own page with full detail, but here’s what we run into locally:
Air Duct Cleaning in Longwood
We clean the full supply and return network using a Rotobrush rotary brush system paired with negative-air extraction from Nikro equipment. In Longwood, this means dislodging organic debris that’s glued itself to damp duct walls, then pulling it out before it recirculates. We photograph the interior before and after, and we price by the system, not by the vent. Air Duct Cleaning in Longwood covers our full process, including how we handle older flex ductwork without damaging it further.
Dryer Vent Cleaning in Longwood
Longwood’s humidity means lint clumps heavier and sticks to vent walls longer, especially on runs through hot attics where condensation meets dryer exhaust. We clean the full vent path from the back of the dryer to the exterior termination, using rotary tools and airflow meters to verify the result. A blocked dryer vent in this climate is a genuine fire hazard, and we treat it that way. Dryer Vent Cleaning in Longwood has the full breakdown.
Duct Sealing in Longwood
With ducts running pressurized and damp year-round, leaks in Longwood homes waste more energy and pull in more attic air than in seasonal markets. We seal accessible ductwork with mastic and mechanical fasteners, then test with a duct blaster to measure the improvement. This is especially valuable in the older ranch homes where original flex runs have separated at the collars. Duct Sealing in Longwood explains our testing and sealing process.

What pushes Longwood jobs toward the higher end: multiple AC systems, original flex ductwork that requires gentler handling, visible mold requiring pre-treatment, and attic access limited by low-pitch roofs common in the 1970s builds. What keeps them lower: newer rigid metal trunks, open attic space, and systems maintained on schedule. Either way, we write the price down before we start, and that number does not move at the door.
