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 Garrison, MD
Air duct cleaning in Garrison, MD typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. What drives the price isn’t the square footage alone; it’s whether your home has the original gravity ducts of an 1850s stone farmhouse or the flexible insulated runs of a 1960s Garrison Farms split-level. Hollis Air Duct Cleaning, part of the Garrison Partners family, sends background-checked, uniformed technicians with Rotobrush and Nikro equipment to handle both. Call (361) 326-5060 for a written estimate before any work starts.
Why Garrison Homes Are Different
Garrison sits in the valley of the Jones Falls, and that terrain shapes every job we do. The older stone and brick homes along Garrison Forest Road and in the Riderwood area have original gravity or drop ducts with no basement return trunk. Cleaning these means hand-and-brush work through narrow chases, sometimes rubble-filled, rather than a standard rotary vacuum sweep. We’ve found mortar crumbs and historic coal ash settled in low spots where ducts thread through original rubble-stone foundation walls. The telltale grey dust tells us we’re disturbing 150-year-old coal soot, not ordinary household dust, and we adjust our approach accordingly.
The newer Garrison Farms colonials and split-levels present the opposite problem: flexible insulated duct runs that sag, kink, and collect squirrel-nest debris seasonally. Many 1950s-60s brick homes have only one or two supply trunks per floor and no return duct network at all. Return air travels through wall cavities, so duct cleaning often means clearing dust-laden stud bays accessible only through baseboard registers.
Garrison’s humid Mid-Atlantic summers and cold, wet winters keep HVAC systems running hard year-round. The valley’s dense oak, maple, and tulip poplar canopy loads return-side ducts with pollen and leaf litter every spring. Winter condensation on cold metal duct runs in unheated attics and crawlspaces promotes mold colonization that becomes airborne on the next heating cycle. These aren’t theoretical concerns; they’re what we account for when we price a job and choose our equipment.
Our Main Garrison Services
Most Garrison homeowners call us for one of three services. Each has its own page with detailed pricing, process, and local conditions.
Air Duct Cleaning in Garrison
We clean supply and return ductwork with Rotobrush rotary brush systems and Nikro negative-air machines that pull dislodged debris out of the home rather than redistributing it. In Garrison’s older stone homes, we often switch to hand brushing and HEPA vacuums when duct chases are too narrow or fragile for rotary heads. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Garrison
Dryer Vent Cleaning in Garrison
Dryer vent cleaning in Garrison means dealing with longer vent runs common in split-level and colonial floor plans, plus lint accumulation accelerated by humid summer air that keeps moisture trapped in flex lines. We clear the full run from dryer to termination, check for proper airflow, and note any code issues with plastic or foil flex transitions. A clogged dryer vent is a genuine fire hazard; we treat it with the urgency it deserves. Dryer Vent Cleaning in Garrison
Duct Sealing in Garrison
Duct sealing addresses the leaks and gaps that waste conditioned air in Garrison’s older homes, where mastic has cracked or metal seams have separated after decades of thermal cycling. We use professional-grade sealing mastic and, where appropriate, aerosol-based duct sealing to pressurize and seal the entire system from inside. This is especially effective in homes with wall-cavity returns that can’t be accessed for manual sealing. Duct Sealing in Garrison

Yes. Many Garrison homes, especially older stone and brick properties, lack basements entirely. We access ducts through registers, crawlspaces, and attic hatches using portable Nikro negative-air units and hand tools. The method changes; the result doesn’t.
