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 Casselberry, FL
Air duct cleaning in Casselberry typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. The city’s mix of 1970s ranch homes, dense oak canopy, and humid subtropical climate creates duct contamination patterns we don’t see in newer Central Florida suburbs. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews work Casselberry jobs with rotary brush systems and negative-air machines from Rotobrush and Nikro. Call (361) 326-5060 for a written estimate before any work starts.
Why Casselberry Homes Are Different
Casselberry’s housing stock sets it apart from Seminole County neighbors. Most homes are single-story ranches and split-levels built between 1960 and 1990, with flexible ductwork snaking through attics that hit 140°F in July and August. That heat degrades the duct liner over time, releasing fiberglass particles into the air supply. We’ve found this problem far more common here than in newer cities like Oviedo or Winter Springs.
The city’s dense tree canopy of live oaks and pines creates another issue: year-round pollen bombardment. Spring oak pollen and fall pine pollen get sucked into outdoor HVAC intakes, coating the inside of ductwork. Summer afternoon thunderstorms, especially around Casselberry Elementary and Secret Lake, cause power surges that trip older air handlers and leave ducts damp. Within 48 hours, mold colonizes that moisture. Many homes have had partial duct replacements too, so we often find mismatched materials, old flex duct joined to newer sections with tape that’s failing in the heat.
Humidity is the constant factor. Casselberry’s subtropical climate means even “dry” months carry enough moisture to support mildew inside poorly sealed returns. Hurricane season adds debris and water intrusion through attic vents. These conditions mean a standard cleaning in Casselberry often reveals more than standard dust.
Our Main Casselberry Services
Casselberry homeowners call us for three jobs, each with its own local challenges and equipment needs.
Air Duct Cleaning in Casselberry
We clean the full supply and return network with a Rotobrush rotary brush system and Nikro negative-air machine, pulling dislodged debris out of the home rather than redistributing it. In Casselberry, we pay special attention to flex duct in hot attics, where degraded liner can tear during cleaning if the technician doesn’t adjust brush speed. We inspect every joint before we start. Air Duct Cleaning in Casselberry covers our full process and what we find in local homes.
Dryer Vent Cleaning in Casselberry
Dryer vent blockages are worse in Casselberry’s older homes because original vent runs were often routed through long attic paths with multiple elbows. Lint accumulates in those low-velocity sections, and the humid climate keeps it damp and sticky. We use rotary brushes and high-velocity air tools to clear the full run, then verify airflow with a meter. Dryer Vent Cleaning in Casselberry explains how we handle roof terminations and long horizontal runs common here.
Duct Sealing in Casselberry
Sealing is critical in Casselberry because attic heat and humidity enter the system through gaps at plenums, joints, and register boots. We apply duct sealing mastic and reinforced mesh to permanent joints, and use specialized tape rated for high-temperature attics on accessible connections. The goal is to stop conditioned air from leaking into the attic and stop attic air from being pulled into the living space. Duct Sealing in Casselberry details our sealing process and how we test results.

FAQs About Air Duct Cleaning Company in Casselberry
No permit is required for standard air duct cleaning or dryer vent cleaning in Casselberry. Duct sealing that involves modifying the plenum or replacing sections of rigid duct may need a permit if it alters the HVAC system’s original design. We check local Seminole County requirements before starting any job that crosses that line, and we handle the paperwork if needed.
Most Casselberry appointments are available within three to five business days. We route crews by ZIP code to minimize drive time and keep arrival windows tight. Calls are answered by a live person 24/7, so you can book or ask questions without waiting for a callback. Call (361) 326-5060 to check this week’s availability.
Few Casselberry HOAs require approval for interior duct cleaning or dryer vent work. If your home has an exterior-mounted HVAC component or roof-access work, some associations ask for advance notice. We can provide a written scope of work for your HOA if needed, and our trucks carry general liability and workers’ compensation documentation for any gate or property manager who asks.
