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 Lansdowne, MD
Air duct cleaning in Lansdowne typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. The borough’s pre-1940 housing stock, gravity-duct retrofits, and humid continental climate mean Lansdowne work requires different equipment and inspection priorities than newer construction. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews serve Lansdowne from our Baltimore office with background-checked, uniformed technicians and written prices before any work starts. Call (361) 326-5060 for a free estimate.
Why Lansdowne Homes Are Different
Lansdowne sits just west of Philadelphia in a humid continental zone with cold winters and hot, sticky summers. HVAC systems here run hard on both ends, so ducts accumulate more dust, pollen, and seasonal allergens than in milder climates. The spring and fall switchovers are when we see the heaviest buildup.
The housing tells the bigger story. Lansdowne’s stock is overwhelmingly 1890s – 1930s Victorian, Colonial, and Tudor Revival homes with original plaster walls and horsehair insulation. Many still have gravity-duct systems that were later retrofitted for forced air, often with furnace and duct runs tucked into basements or attics. That retrofit work left unsealed or partially disconnected segments that pull in debris from wall cavities and unfinished spaces. Along Lansdowne Avenue and near the historic downtown, we regularly find original coal-era ductwork and even old coal chutes still tied into modern systems, carrying decades of accumulated soot and dust.
Homeowners here are renovating, not replacing. Plaster walls and historic character make full HVAC overhauls impractical, so duct cleaning pairs naturally with equipment upgrades in homes where the ductwork outlives three or four furnaces.
Our Main Lansdowne Services
Most Lansdowne homeowners call us for one of three jobs. Each has its own page with full pricing and details.
Air Duct Cleaning in Lansdowne
We clean supply and return ducts with Rotobrush rotary brush systems and Nikro negative-air machines, pulling loosened debris out rather than pushing it deeper. In Lansdowne, we always inspect for coal-era dust layers and gravity-duct retrofits that change access points. Older metal ducts here can handle aggressive brushing, but we adjust for plaster-wall chases that weren’t built for modern airflow. Air Duct Cleaning in Lansdowne covers full pricing and what to expect.
Dryer Vent Cleaning in Lansdowne
Dryer vent cleaning removes lint buildup from the appliance through the exterior cap. Lansdowne’s older homes often have longer vent runs through finished basements or exterior walls with multiple elbows, which trap lint more aggressively than short through-wall runs. We check for proper airflow and intact venting material, replacing foil or plastic transitions with rigid metal where code requires. Dryer Vent Cleaning in Lansdowne has the full breakdown.
Duct Sealing in Lansdowne
Duct sealing closes leaks in supply and return runs with mastic sealant and metal-backed tape, not duct tape. In Lansdowne, unsealed retrofit connections and gaps at plaster-wall penetrations are common culprits for lost airflow and dust infiltration. We pressure-test the system before and after to measure improvement. Duct Sealing in Lansdowne explains the process and pricing.

Yes. Our technicians are trained on older construction and use access points that avoid cutting plaster whenever possible. We inspect gravity-duct retrofits and coal-era chases with cameras before deciding where to enter. If wall access is unavoidable, we discuss it with you first and patch minimally.
