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 Ferndale, MD
Hollis Air Duct Cleaning handles Ferndale jobs differently because Ferndale homes are different. Most were built between 1945 and 1965 with galvanized steel ductwork that has never been opened, and many still run ducts through damp crawlspaces directly under the BWI flight path. If your vents are pushing musty air or your energy bills have climbed without explanation, a full-system cleaning with a written price upfront is the place to start. Call (361) 326-5060 for a free estimate.
Why Ferndale Homes Are Different
Ferndale sits directly under the flight path of BWI Thurgood Marshall Airport, and its older homes take in jet exhaust and particulate that settle deep in ductwork. That, combined with the area’s high water table and humid summers, makes duct cleaning here less about dust and more about biological growth and trapped airport-adjacent grime.
The housing stock tells the rest of the story. Ferndale is dominated by post-WWII Cape Cods, ranchers, and split-levels built between 1945 and 1965, many with original galvanized steel ductwork that has never been professionally cleaned. A large share of these homes still have partial or full crawlspace duct runs, which are notoriously prone to condensation, rodent intrusion, and mold. In the Arundel Gardens and Ferndale Manor neighborhoods, our technicians routinely find ductwork lined with a fine black soot that tests as jet-fuel combustion byproduct – a fingerprint you won’t see in Pasadena or Glen Burnie.
The climate seals the problem. Ferndale’s humid subtropical climate means summers are hot and sticky, and the region’s high water table keeps crawlspaces damp year-round. This creates ideal conditions for mold and mildew growth inside ductwork, especially in homes with unsealed crawlspace ducts. We factor all of this into how we scope, price, and execute every job in Ferndale.
Our Main Ferndale Services
Most Ferndale homeowners call us for one of three jobs, each scoped to the conditions we just described.
Air Duct Cleaning in Ferndale
We clean the full supply and return system with Rotobrush rotary brush systems and Nikro negative-air machines, pulling debris out rather than pushing it deeper. In Ferndale, we pay special attention to crawlspace trunk lines where moisture and airport particulate collect. Every job gets a written price before we start and before-and-after photos of your own ducts. Air Duct Cleaning in Ferndale covers the full process.

Dryer Vent Cleaning in Ferndale
Dryer vents in older Ferndale homes often run through walls or crawlspaces with multiple bends, creating lint traps that standard brushes can’t reach. We use flexible rotary tools and camera inspection to clear the full run, including the exterior cap. Blocked dryer vents are a leading cause of house fires, and Ferndale’s mature neighborhoods see more than their share of hidden clogs. Dryer Vent Cleaning in Ferndale has the details.

Duct Sealing in Ferndale
Original ductwork in Ferndale homes leaks 20 to 30 percent of conditioned air into crawlspaces and wall cavities before it reaches the vents. We seal joints and seams with mastic and reinforced tape, then pressure-test to verify the seal. For homes with unconditioned crawlspace runs, this often drops energy bills more than equipment upgrades. Duct Sealing in Ferndale explains what’s involved.
