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 Essex, MD
Air duct cleaning in Essex, MD typically runs $350 – $650 for a whole-home system and should include both supply and return trunk lines, not just a quick vent wipe. Essex homes sit on tidal marshland between Back River and Middle River, so our crews spend as much time tracking moisture intrusion and mildew in returns as they do removing dust buildup. If you’re seeing musty air when the heat kicks on or humidity readings that won’t drop, call Hollis Air Duct Cleaning at (361) 326-5060 for a free written estimate before any work starts.
Why Essex Homes Are Different
Essex was built largely in the 1940s through 1960s on filled tidal marsh between Back River and Middle River, and that geography still shapes every duct system we open. The housing stock is predominantly brick and formstone rowhouses and small ranch homes, many with original galvanized ductwork or early flex duct tied to older oil-to-gas converted furnaces. Full or partial basements and crawl spaces are common, and they flood or sweat through humid subtropical summers and nor’easter events in ways drier inland Baltimore County towns simply don’t experience.
After a Back River flood or a heavy humid stretch, our techs in riverside blocks around Sandalwood and Hyde Park regularly find standing water in basement duct boots and musty returns that trace back to crawl-space vapor, not normal household dust. That dampness feeds mildew in duct liners and insulation that rotary brushing alone won’t solve. We often pair duct cleaning with moisture-source identification, because in Essex the problem is rarely just dust accumulation. Homes here need a crew that understands the difference between a dry-duct job and a marshland-duct job.
Our Main Essex Services
Essex homeowners call us for three core jobs, each shaped by the humidity, housing age, and river-adjacent conditions here.
Air Duct Cleaning in Essex
Our Air Duct Cleaning in Essex covers the full system: supply trunk, return trunk, branch lines, and boots, using Rotobrush rotary brush systems and Nikro negative-air machines to pull loosened debris out rather than push it deeper. In Essex we pay special attention to return plenums and flex duct in crawl spaces, where tidal humidity has often started mildew growth long before homeowners notice the smell. Every job gets a written price before we touch the system.
Dryer Vent Cleaning in Essex
Our Dryer Vent Cleaning in Essex removes lint buildup from the appliance connection through the exterior cap, using professional-grade brushing and high-velocity air tools. In Essex’s older ranches and rowhouses, we frequently find vents routed through crawl spaces or long horizontal runs that sag and trap moisture from the surrounding air, accelerating blockage. We inspect the full run and note any structural issues that could shorten the cleaning interval.
Duct Sealing in Essex
Our Duct Sealing in Essex closes leaks in trunk lines, plenums, and connections using mastic and mechanical sealing methods appropriate for galvanized or flex duct. In Essex’s humid environment, unsealed return leaks in crawl spaces pull in mold spores and river-area moisture that bypass the filter entirely. Sealing returns is often the single most effective step to stop musty air after cleaning is complete.
