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 Philadelphia, PA
Air duct cleaning in Philadelphia runs $350 – $650 for a typical single-system home, with most jobs completed in one visit. What drives the price isn’t the equipment; it’s the house. Philadelphia’s pre-1950 rowhouses, retrofitted gravity ducts, and shared party-wall returns make every job a custom assessment, not a standard package. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our Philadelphia office dispatches crews who know the difference between a Center City brownstone and a South Philly row. Call us at (361) 326-5060 for a free estimate.
Why Philadelphia Homes Are Different
Philadelphia’s housing stock is among the oldest in the nation. In Kensington, Fishtown, and South Philadelphia, you’ll find narrow rowhouses built between 1870 and 1930 with HVAC systems retrofitted decades after original construction. That means short, irregular duct runs, original gravity ducts still in service, and plenty of asbestos-wrapped or uninsulated metal in basements and crawlspaces.
The humid subtropical climate here doesn’t help. Hot, sticky summers and cold winters create condensation inside ducts when they pass through warm, unconditioned spaces. That moisture promotes mold and bacterial growth. Come winter, dry forced-air heating stirs up accumulated dust. Many homeowners notice the cycle: musty smells in July, dust clouds in January.
Then there’s the party-wall problem. In South Philadelphia especially, shared return ducts run the full height of rowhouses, accessed only through small original grilles. A blockage affects multiple floors. Technicians from outside the city often miss this entirely. We’ve learned to check it every time.
Our Main Philadelphia Services
Philadelphia homeowners call us for three jobs, each with its own challenges in this market. Here’s what we handle and where to read more.
Air Duct Cleaning in Philadelphia
We clean supply and return ducts with Rotobrush rotary brush systems and Nikro negative-air machines, pulling debris out rather than pushing it deeper. In Philadelphia, we often find unlined original ductwork in rowhouse crawlspaces, which requires gentler brush contact and careful sealing afterward. Every job gets a written price before we start and a 365-Day Done Right Promise in writing. Air Duct Cleaning in Philadelphia covers our full process, equipment, and what to expect in older homes.
Dryer Vent Cleaning in Philadelphia
Dryer vent cleaning in Philadelphia rowhouses means navigating tight utility closets, long horizontal runs through masonry walls, and vents that terminate in shared light wells. Lint accumulation is worse here because humid summers keep moisture in the line, clumping debris. We use high-velocity air tools and inspect the full run with a camera when access is limited. Dryer Vent Cleaning in Philadelphia explains our process and why blocked vents are a genuine fire hazard in these older buildings.
Duct Sealing in Philadelphia
Duct sealing with mastic and mechanical fasteners stops conditioned air from leaking into unheated basements, crawlspaces, and party walls. In Philadelphia, we see significant leakage at joints in retrofitted systems where ducts were cut to fit spaces never designed for them. Sealing can improve airflow to second and third floors in rowhouses where upstairs rooms never get warm. Duct Sealing in Philadelphia details our sealing methods and how we test results with a pressure pan.
