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 Perry Hall, MD
Air duct cleaning in Perry Hall typically runs $350 – $650 for a whole-home system, with most jobs scheduled in spring after the oak and maple pollen drop or in early fall before heating season kicks in. We’re Hollis Air Duct Cleaning, and we’ve built our Perry Hall work around the reality of this area’s housing stock and climate: long flexible duct runs in attics, humid summers that keep coils damp, and pollen loads heavy enough to clog returns in a single season. If you’re ready to book, call us at (361) 326-5060. We price every job in writing before we start, and every visit is covered by our 365-Day Done Right Promise.
Why Perry Hall Homes Are Different
Perry Hall sits in Baltimore County’s humid-subtropical transition zone, where the Gunpowder Falls corridor feeds heavy spring pollen and fall leaf mold straight into HVAC returns. The local housing stock skews toward the 1970s – 2000s suburban build-out: two-story colonials, split-levels, and townhomes with long flex-duct runs through hot attics and between floors. That geometry traps dust and condensate differently than the short metal trunks in pre-war city housing.
We see the pattern every April. The late pollen dump from surrounding oak and maple canopy hits while AC systems are already running, so returns clog fast and homeowners notice the drop in airflow. Winters here are cold enough to shrink duct seals and pull in attic dust, which means the same house often needs attention twice a year, not once every three to five. Dispatch and scheduling for our Perry Hall crews are coordinated from our Baltimore office, with local techs who know the difference between a Gunpowder-area ranch and a Honeygo split-level.
Our Main Perry Hall Services
Most Perry Hall homeowners call us for one of three jobs. Each has its own page with full detail on what we do, what it costs, and how we handle the local conditions.
Air Duct Cleaning in Perry Hall
We clean the full supply and return network with a Rotobrush rotary brush system and negative-air extraction from Nikro equipment. In Perry Hall, that means pulling pollen-compacted dust out of long flex-duct runs and treating metal trunks for microbial growth where humid summers have kept them damp. We photograph the before and after so you see what came out. Air Duct Cleaning in Perry Hall covers the full process and pricing.
Dryer Vent Cleaning in Perry Hall
Dryer vents in Perry Hall’s older townhome rows and split-levels often run longer than code ideal, with multiple bends that trap lint behind the reduced airflow. We use rotary brushes and high-velocity air to clear the full run from appliance to termination, then verify flow with a meter. Longer vents and bird-guard terminations common here add time, but we price it before we start. Dryer Vent Cleaning in Perry Hall has the details.
Duct Sealing in Perry Hall
Perry Hall’s temperature swings shrink and expand duct seams, especially in attic flex-duct connections. We seal with mastic and mechanical fasteners, then pressure-test to confirm the fix. Sealing before cleaning keeps new contaminants from entering through gaps, and it cuts the energy loss that makes upstairs rooms cold in January. Duct Sealing in Perry Hall explains when it makes sense.
