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 Alexandria, VA
Air duct cleaning in Alexandria runs $350 – $650 for a typical single-system home, with most jobs scheduled within a week and completed in one day. What separates Alexandria from nearby Northern Virginia markets is the housing stock itself: 18th-century rowhouses with retrofit ductwork demand entirely different techniques than 1980s colonials with modern flexible runs. At Hollis Air Duct Cleaning, we price every job in writing before we start, and every technician arrives background-checked, uniformed, and equipped with Rotobrush rotary systems and Nikro negative-air machines calibrated to the house in front of us. Call (361) 326-5060 for a free estimate.
Why Alexandria Homes Are Different
Alexandria is not one housing market. It’s two, split by Route 1 and the Metro line.
In Old Town and the historic district, we regularly work in 1700s and 1800s rowhouses with original plaster walls, heart-pine floors, and ductwork retrofitted into closets, soffits, or between party walls. These chases are narrow, often uninsulated, and historically regulated; aggressive cleaning damages plaster or loosens century-old structure. Our crews use hand-guided rotary brushes with reduced torque and portable HEPA containment, not the high-suction truck-mounted rigs we deploy elsewhere.
Cross into the West End, Kingstowne, or the Carlyle district and the picture flips: 1960s – 1980s colonials and 1990s – 2000s townhomes with long flexible duct runs, finished basements, and tight building envelopes. Here, negative-air extraction and rotary whipping work best, but the tight construction traps humidity, so we also check for condensation pooling in low spots.
Alexandria’s humid subtropical climate amplifies everything. Summers hit the mid-90s with heavy moisture; winters bring damp cold snaps. Mold and dust mites thrive in unsealed historic chases, while spring oak, maple, and elm pollen loads the system with allergens through May. Post-pollen-season cleanings are common here for good reason. In Old Town specifically, retrofit ducts running through unheated attics or between party walls collect condensation during cold snaps, leading to rust and microbial growth rarely seen in newer construction.
Our Main Alexandria Services
Homeowners in Alexandria call us for three core services, each handled with equipment and techniques matched to the house type.
Air Duct Cleaning in Alexandria
Our full-system cleaning removes accumulated dust, pollen, and microbial growth from supply and return ducts, registers, and the air handler. In Old Town rowhouses, we often encounter adapted gravity-furnace ductwork from the 19th century, requiring technicians to map the system before selecting brush stiffness and suction pressure. In West End homes, we focus on flex-duct integrity and condensation points. Every job includes before-and-after photos of your own ducts and a written price locked before work begins.

Dryer Vent Cleaning in Alexandria
Dryer vent cleaning in Alexandria addresses a genuine fire hazard, not a convenience upgrade. Lint accumulation restricts airflow, overheats the dryer, and ignites more often than most homeowners realize. Historic homes often have vent runs routed through multiple floors or exterior masonry walls; newer townhomes may have long horizontal runs under slabs or through attics. We clear the full run from dryer to termination, inspect for proper airflow, and verify the exterior hood operates freely. Dryer Vent Cleaning in Alexandria
Duct Sealing in Alexandria
Duct sealing stops conditioned air from leaking into attics, crawl spaces, and between walls. In Alexandria, this matters most in two places: Old Town homes where decades of retrofit work has left gaps at chase penetrations, and West End homes where flexible duct connections have loosened over time. We use mastic and mechanical sealing, then verify results with pressure testing. Sealed ducts cut utility bills and reduce the humidity load that drives mold growth in this climate.
