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 Darby, PA
Air duct cleaning in Darby typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. What drives the price isn’t the size of the house alone; it’s the age and condition of the ductwork itself. Darby’s century-old housing stock means we regularly encounter galvanized steel ducts with decades of rust, coal dust residue, and moisture damage that newer suburban systems simply don’t present. Our crews are dispatched from the Philadelphia office and serve Darby directly. Call (361) 326-5060 for a free written estimate.
Why Darby Homes Are Different
Darby’s built environment shapes every job we do here. The borough is dense with early-1900s rowhomes and twin homes, many still running original galvanized steel ductwork that rusts from the inside out. In pre-1950s properties along Walnut Street and Main Street corridors, we regularly find coal dust and ash residue trapped in supply runs, leftover from when homes were heated by coal furnaces. Removing this safely requires HEPA containment from Abatement Technologies so nothing disperses into living spaces during the cleaning.
The geography adds another layer. Darby sits along Darby Creek and within the Delaware River floodplain, which means high baseline humidity and occasional water intrusion into basements and crawl spaces where ductwork runs. After heavy rains, we get calls about musty airflow and visible mold in floor registers. The humid continental climate, hot sticky summers followed by cold dry winters, accelerates both mold growth and dust mite activity inside ducts. Renovations are common here as owners retrofit aging systems, and we often find mismatched or disconnected duct runs that need careful inspection and sealing during cleaning.
Our Main Darby Services
Homeowners in Darby call us most often for three jobs, each with its own page and pricing.
Air Duct Cleaning in Darby
We clean the full supply and return system using a Rotobrush rotary brush system or negative-air method depending on duct material and contamination level. In Darby, this usually means addressing rust scale from galvanized steel, coal dust in older homes, and mold remediation in flood-affected properties. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Darby
Dryer Vent Cleaning in Darby
Dryer vent cleaning removes lint buildup from the appliance through the exterior termination, reducing fire risk and improving drying efficiency. Darby’s older rowhomes often have long, convoluted vent runs through multiple floors or shared walls between twins, which trap lint and require specialized tools to clear completely. We inspect the full run and provide before-and-after photos. Dryer Vent Cleaning in Darby
Duct Sealing in Darby
Duct sealing closes leaks in the supply and return system using mastic sealant or aerosol-based methods, stopping conditioned air from escaping into attics, crawl spaces, or between walls. In Darby, this is critical where renovations have left disconnected runs or where rust has eaten through galvanized steel joints. We pressure-test the system before and after to verify results.
