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 Deale, MD
Air duct cleaning in Deale, MD typically costs $350 – $650 for a whole-home system and should include antimicrobial treatment because of the area’s humidity and salt air. Hollis Air Duct Cleaning handles the specific challenges of Chesapeake Bay homes: mold-prone ducts in seasonal rentals, corroded metal components from salt exposure, and older waterfront cottages with original ductwork. We’re part of the Garrison Partners family, and every Deale job gets a written price before we start, background-checked uniformed technicians, and our 365-Day Done Right Promise. Call us at (361) 326-5060 for a free estimate.
Why Deale Homes Are Different
Deale sits on the Chesapeake Bay in Anne Arundel County, and that location changes everything about how we approach ductwork. The humid subtropical climate here means hot, sticky summers and mild, damp winters. When a vacation rental on Franklin Gibson Road or a waterfront cottage on Rockhold Creek sits closed up for three months, condensation builds inside the ducts. We’ve opened vents in September and found visible mold growth that wasn’t there in May.
The salt air accelerates corrosion on older galvanized ductwork, especially in the original cottages near the marinas. We’ve replaced sections of metal duct in Deale homes that showed pitting you’d expect after twenty years inland. Newer townhomes off Deale Road often use flex duct, which traps moisture if the sealing failed during construction. Our crews carry moisture meters and check humidity levels at the return, not just vacuum out debris. The Garrison Standard requires us to report what we find, not just clean what’s visible.
Our Main Deale Services
Most Deale homeowners call us for one of three jobs, each shaped by the local climate and housing stock.
Air Duct Cleaning in Deale
We clean the full supply and return system with a Rotobrush rotary brush and Nikro negative-air machine, pulling debris toward the vacuum so nothing escapes into your living space. In Deale, we also apply antimicrobial treatment to every vent because of the humidity load from the Bay. We document before-and-after photos of your own ducts, not stock images. Air Duct Cleaning in Deale covers the full process and what to expect when we arrive.
Dryer Vent Cleaning in Deale
Dryer vents in Deale’s older cottages often run through unconditioned crawl spaces or exterior walls where humidity condenses and mixes with lint into a paste that standard brushes can’t clear. We use a rotary whip system and check the termination cap for salt corrosion. A blocked dryer vent in a humid climate is a genuine fire hazard, and we treat it that way. Dryer Vent Cleaning in Deale explains our full protocol.
Duct Sealing in Deale
Leaky ducts in Deale waste more energy than inland homes because the humidity difference is so extreme. Unconditioned attic or crawl space air gets pulled into leaks every time the system runs. We seal with mastic and mechanical fasteners, then pressure-test to verify. For flex duct with moisture damage, sealing alone won’t fix it; we’ll tell you straight. Duct Sealing in Deale covers when sealing helps and when replacement makes more sense.
