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 Swarthmore, PA
Air duct cleaning in Swarthmore runs $350 – $650 for most whole-home systems, with older homes often landing higher due to access challenges. We’re Hollis Air Duct Cleaning, and we’ve learned that Swarthmore jobs aren’t like standard suburban calls. The borough’s pre-1940 housing stock, tree canopy, and humid continental climate create a specific set of problems: pollen-laden return ducts, mold-prone supply runs, and ductwork hidden behind original plaster that demands careful, low-impact equipment. Our technicians use Rotobrush rotary systems and Nikro negative-air machines sized for tight crawlspaces and finished basements. Call (361) 326-5060 for a free estimate.
Why Swarthmore Homes Are Different
Swarthmore’s housing is genuinely old. Most homes are center-hall Colonials, Tudors, and Victorians built before 1940, with original plaster walls and millwork that can’t take rough handling. Ductwork arrived later, often during mid-century renovations, which means short, irregular runs tucked behind finished basements or into crawlspaces with limited access. We can’t just ram a standard brush through these systems. Our crews size the equipment to the opening, protect the plaster, and work methodically.
The climate compounds this. Humid summers and cold winters create condensation cycles inside ductwork, especially where insulation has settled or gaps let attic air meet conditioned air. Mold and mildew follow. Spring brings pollen from oak, maple, and sycamore trees that mat into filters and return grilles. Near the Swarthmore College campus, we’ve pulled fibrous seed pods from London plane trees out of ducts – debris that standard suburban equipment isn’t always configured to handle. The Garrison Standard requires us to inspect before we quote, so we know what we’re walking into before we bring a machine through your door.
Our Main Swarthmore Services
Most Swarthmore homeowners call us for one of three jobs. Each has its own page with detailed pricing and process information.
Air Duct Cleaning in Swarthmore
We clean supply and return ductwork with a rotary brush system that loosens debris and a negative-air machine that pulls it out under controlled suction. In Swarthmore, this means navigating original plaster walls, protecting finished basements, and often finding decades of pollen and fine tree debris packed into returns. We photograph the before condition, clean every accessible run, and show you the after. Air Duct Cleaning in Swarthmore covers full pricing and what’s included.
Dryer Vent Cleaning in Swarthmore
Dryer vents in older Swarthmore homes often run through exterior masonry or long horizontal paths to side walls, creating lint traps that standard brushes can’t fully clear. We use flexible augers and high-velocity air tools to break up packed lint without damaging the vent pipe. Every cleaning includes airflow testing before and after. Dryer Vent Cleaning in Swarthmore has full details on our process.
Duct Sealing in Swarthmore
Leaky ductwork in Swarthmore’s older homes wastes conditioned air into attics, crawlspaces, and wall cavities. We seal accessible joints with mastic and apply aerosolized sealant where manual access isn’t possible. The work is especially effective in homes with mid-century duct additions, where original installers often left gaps at connections. Duct Sealing in Swarthmore explains how we test for leaks and what improvement to expect.
