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.
Air Duct Cleaning Company in Collingdale, PA
Air duct cleaning in Collingdale runs $320 – $580 for a typical rowhouse system, with most jobs scheduled within a week. We’re Hollis Air Duct Cleaning, and we’ve learned that Collingdale isn’t a standard suburban duct job. The borough’s dense grid of 1920s – 1950s rowhouses, shared party-wall chases, and original galvanized ductwork create contamination patterns you won’t find in newer construction. Call (361) 326-5060 for a free estimate with a written price before any work starts.
Why Collingdale Homes Are Different
Collingdale’s housing stock shapes every duct cleaning job we do here. The borough is packed with narrow-lot brick and stucco rowhouses built between the 1920s and 1950s, many still running on original galvanized or early rigid metal ductwork with joints that have loosened over nearly a century. These systems don’t sit in conditioned attics or crawlspaces. They run through cold, uninsulated wall cavities and shared party-wall chases that connect adjacent units.
That construction matters because it means your return ducts can pull in dust, mold spores, and even lint from the neighboring rowhouse through gaps in the chase. We’ve seen it on Ashland Avenue and MacDade Boulevard blocks: clean one unit, skip the chase, and the contamination migrates back within weeks. The Philadelphia-area climate sharpens the problem. Humid July air condenses inside those cold wall cavities, and when the heat first kicks on in October, the system draws in damp, musty air that’s been sitting stagnant for months. That’s when our phones ring.
Our technicians are trained to inspect party-wall chases and shared returns before quoting any Collingdale job. It’s not an upsell. It’s the only way to do the work right in this borough.
Our Main Collingdale Services
Most Collingdale homeowners call us for one of three jobs. Each has its own page with full pricing, process details, and neighborhood-specific notes.
Air Duct Cleaning in Collingdale
We clean supply and return ductwork using a Rotobrush rotary brush system for the main trunk lines and branch ducts, combined with a Nikro negative-air machine that pulls dislodged debris out of the system rather than pushing it into your rooms. In Collingdale rowhouses, we pay special attention to returns that draw through shared wall chases, and we’ll show you photos of what we found before we pack up. Air Duct Cleaning in Collingdale covers full pricing and what to expect on the day of service.

Dryer Vent Cleaning in Collingdale
Dryer vents in Collingdale rowhouses often run long, horizontal routes through shared walls before exiting at the rear or roofline, and lint buildup in these extended runs is a real fire hazard. We use rotary brushes and high-velocity air tools to clear the full run, then verify airflow with a meter. If your dryer takes two cycles to dry a load, the vent is likely restricted. Dryer Vent Cleaning in Collingdale has full details and warning signs to watch for.

Duct Sealing in Collingdale
Leaky duct joints in Collingdale’s older metal systems waste heated and cooled air into wall cavities, driving up utility bills and pulling in contaminants. We seal accessible joints with duct sealing mastic and reinforced tape, then pressure-test the system to verify the improvement. In rowhouses with shared chases, sealing the leaks that connect to neighboring units can also reduce cross-contamination. Duct Sealing in Collingdale explains when sealing makes sense versus when replacement is the smarter call.

What pushes Collingdale prices toward the high end: shared party-wall chases that need isolation, original galvanized ductwork with heavy rust or debris buildup, and systems that haven’t been cleaned in 10-plus years. What keeps them lower: standard rigid metal in good condition, recent prior cleaning, and accessible basement or utility-closet layouts. Either way, you’ll get one flat price per system, written down before we start, and it doesn’t move at the door.
