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 Arnold, MD
Air duct cleaning in Arnold, MD typically runs $450 – $850 for a whole-home system, with most jobs completed in a single visit. Arnold’s location between the Magothy and Severn rivers creates unique duct conditions that inland Maryland towns simply don’t face. We’re Hollis Air Duct Cleaning, and our crews serving Arnold understand that river humidity, older galvanized ductwork, and crawlspace moisture mean this work requires different preparation and equipment than drier areas. Call us at (361) 326-5060 for a written estimate before any work begins.
Why Arnold Homes Are Different
Arnold sits on a narrow strip of Anne Arundel County land between two tidal rivers, and that geography changes everything about what’s living in your ducts. The water table here sits high, summer air stays thick with moisture even when the sun is out, and morning fog rolls in regularly off both the Magothy and Severn. That persistent dampness keeps crawlspaces and attics wet year-round, which means mold spores, mildew, and musty river debris accumulate in ductwork far faster than they do in drier inland communities like Millersville or Severna Park.
Much of Arnold’s housing stock was built between the 1970s and 1990s: colonials, split-levels, and ranchers with original galvanized steel or early flexible ductwork. In the older sections off Ritchie Highway and College Parkway, supply lines often run through unconditioned crawlspaces where river humidity accelerates corrosion. We’ve opened systems in Arnold where the galvanized ducts were more rust than metal, and the flex duct had trapped enough condensation to support visible microbial growth. A technician who treats this like a standard dust-removal job is missing the actual problem.
Homeowners here also deal with tighter lot lines and mature tree cover that keeps foundations shaded and slow to dry. The combination of aging infrastructure and environmental moisture means Arnold duct cleaning often involves section replacement and antimicrobial treatment, not just a vacuum pass.
Our Main Arnold Services
Arnold homeowners call us most often for three jobs: full air duct cleaning, dryer vent cleaning, and duct sealing. Each service has its own page with detailed pricing and process information.
Air Duct Cleaning in Arnold
Our Arnold air duct cleaning jobs start with a camera inspection of the trunk lines and branch ducts, because river humidity here hides problems that a quick glance misses. We use Rotobrush rotary brush systems to dislodge debris from galvanized and flex ductwork, paired with Nikro negative-air machines to pull it out without redistributing spores through the house. In Arnold’s older neighborhoods, we regularly find corroded supply lines in crawlspaces that need section replacement before cleaning can be effective. Air Duct Cleaning in Arnold covers our full process, pricing, and what to expect on the day of service.

Dryer Vent Cleaning in Arnold
Dryer vent cleaning in Arnold faces the same moisture challenges: lint compacts and clings in humid duct runs, especially in longer vent paths through crawlspaces or exterior walls. We pull the full lint column with professional-grade extraction tools and inspect the termination cap for proper clearance, which matters in Arnold’s tighter lot configurations. Blocked dryer vents are a genuine fire hazard, and the humid climate here makes buildup worse than in drier areas. Dryer Vent Cleaning in Arnold has full details on our process and flat-rate pricing.

Duct Sealing in Arnold
Duct sealing in Arnold addresses the leaks and separations that river humidity makes worse: every gap pulls damp crawlspace air into the system, accelerating mold growth and wasting conditioned air. We apply mastic sealant and mechanical fasteners to reconnect separated joints, then pressure-test the system to verify sealed performance. In Arnold’s 1970s – 1990s stock, we often find original duct tape that’s dried and failed, or flex duct that’s pulled loose at the collar. Duct Sealing in Arnold explains our sealing process and how it pairs with cleaning for a complete system restoration.
