Air Duct Cleaning in Washington - One Flat Price, Before-and-After Photos

Fast, Reliable Air Duct Cleaning Across Washington

If you’re noticing dust settling on furniture hours after cleaning, or your allergies flare up every time the AC kicks on, your ductwork is likely circulating years of buildup instead of clean air. In Washington, where humid summers run from May through September and pollen from cherry, oak, and elm trees coats the city each spring, dirty ducts aren’t just a nuisance. They become a reservoir for mold, mildew, and allergens that recirculate through your home every time the system cycles.

Call (361) 326-5060

We dispatch from our Washington, DC metro office and serve homes from Capitol Hill to Georgetown, Shaw to Dupont Circle. Our crews know the difference between a 19th-century rowhouse with original galvanized steel ducts wedged between party walls and a mid-century apartment with retrofitted flex runs. That local knowledge matters because the wrong approach on historic housing stock can damage plaster, violate historic district guidelines, or leave you with a bigger mess than you started with. Call (361) 326-5060 for a free estimate. We’ll give you a written price before any work begins.

Why Hollis Air Duct Cleaning Is Washington’s Preferred Air Duct Cleaning Company

We’ve been part of the Garrison Partners family since 2004, and our Washington operation runs on The Garrison Standard. That means our technicians arrive inside the quoted window, price every job in writing before touching equipment, and leave the site clean. In a city where many of our clients are federal employees, diplomats, or busy professionals who can’t afford to waste a day waiting on a no-show, reliability isn’t a selling point. It’s the baseline.

Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. We use professional-grade equipment from Rotobrush and Nikro, the same negative-air machines and rotary brush systems commercial crews rely on, because Washington’s aging ductwork demands tools that can handle original galvanized steel and asbestos-wrapped runs without tearing them apart.

Roy Castellanos leads our operation here in Washington, and every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround. Our phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues, no waiting until Monday when your system is blowing dust into every room.

Commercial Air Duct Cleaning in Washington

Commercial Air Duct Cleaning in Washington addresses a different set of challenges than residential work, from brutalist federal buildings with massive centralized systems to historic office conversions on K Street where ductwork was retrofitted into spaces never designed for modern HVAC. We clean supply and return runs, main trunk lines, and diffusers using negative-air methods that contain debris rather than spreading it through occupied spaces. A typical commercial system cleaning in Washington runs $800 – $2,400 depending on square footage, system accessibility, and whether video inspection reveals blockages or contamination that requires targeted remediation.

Federal and Institutional Buildings

Government buildings and embassies near Foggy Bottom and along Massachusetts Avenue require discreet crews who understand security protocols and can work around classified environments without disrupting operations. Our technicians carry identification verifiable through our office and follow The Garrison Code for conduct on sensitive sites.

Historic Office Conversions

Buildings converted from 19th-century rowhouses or early 20th-century commercial structures in Shaw and the U Street corridor often have ductwork threaded through masonry chases with no original access panels. We use specialized camera systems to map runs before cutting, minimizing intrusion into finished spaces and preserving historic fabric.

Air Duct Cleaning Services in Washington

Air Duct Cleaning Services in Washington cover the full range of residential and light commercial systems, from single-family homes in Cleveland Park to condo units in Navy Yard. A typical whole-system residential cleaning here runs $400 – $700 for a standard home, with larger historic properties or homes requiring wall access for original duct runs falling toward the higher end. We clean supply ducts, return ducts, main trunk lines, and registers using a combination of rotary brush agitation and negative-air extraction that removes debris rather than pushing it deeper into the system.

Video Inspection and Assessment

Before we recommend any cleaning, we feed a camera through your ductwork to show you what’s actually in there. In Washington’s older housing stock, we regularly find collapsed flex duct in retrofits, rusted galvanized steel shedding particles into airflow, and pollen compaction so severe it restricts airflow by 30% or more.

Full System Cleaning

We don’t clean two registers and call it done. Our full system service covers every accessible component of your duct network, from the return plenum to the last supply boot, with before-and-after photos of your own ducts so you can verify the work was actually performed.

Trusted Brands We Service in Washington

Our equipment roster includes Rotobrush rotary brush systems for agitating debris off duct walls, Nikro negative-air machines that maintain suction and contain contaminants during cleaning, and filtration products from Honeywell and Guardsman that we install when homeowners want to maintain cleaner air between service visits. We stock parts and filters for these brands locally in Washington, so if your cleaning reveals a failing component, we can often address it during the same visit rather than scheduling a return trip. This matters in a city where parking is a logistical challenge and our clients’ time is valuable.

Common Air Duct Cleaning Problems We See in Washington Homes

• Pollen compaction during cherry blossom season. Every April, calls surge roughly 30% as oak, elm, and cherry pollen infiltrates ductwork through gaps in aging window units and poorly sealed returns. The pollen mixes with DC’s summer humidity and compacts into a paste that restricts airflow and feeds mold growth.
• Original galvanized steel ducts shedding rust and scale. In Capitol Hill and Georgetown rowhouses built before 1940, we regularly find supply runs where the interior coating has degraded, releasing metallic particles into living spaces every time the blower engages.
• Asbestos-wrapped ducts in mid-century buildings. Many 1950s and 1960s apartment buildings in Southwest DC and along Connecticut Avenue have ducts wrapped in friable asbestos insulation. Disturbing these requires specialized containment and abatement protocols that our crews are trained to recognize and handle safely.
• Retrofit flex duct crushed in masonry chases. When modern HVAC was added to historic structures, installers often forced flex duct through gaps between plaster and brick that were never designed for it. We find collapsed or kinked runs that reduce airflow to entire wings of a house, particularly in Shaw and Logan Circle.
