Fast, Reliable Air Duct Cleaning Across Alexandria
Air duct cleaning in Alexandria typically costs $320-$580 for a full residential system, and most jobs are completed in a single visit. Our Air Duct Cleaning team has been serving homes along the Potomac for over 42 years, and we answer calls with a live person 24 hours a day at (844) 685-6342. Alexandria’s mix of 18th-century row houses, 1920s bungalows, and postwar ranch-style homes creates ductwork challenges you won’t find in standard suburban construction. We’ve cleaned systems in Old Town’s Federal-style brick homes, Del Ray’s craftsman cottages, and the 1950s-1970s garden apartments south of Duke Street. Each neighborhood presents its own puzzle, and we’ve built our approach around solving them without surprises on the bill.
Why Bellows Air Duct & Vent Co. Is Alexandria’s Preferred Air Duct Cleaning Company
We’ve earned our reputation in Alexandria by showing up when we say we will and leaving camera proof of what we found and what we removed. Our technicians are background-checked, uniformed, and trained on the specialized equipment that historic homes demand. In a city where many duct systems were retrofitted decades after the walls went up, standard brushes and shop vacs often fail. We don’t.
Our customers in the 22301, 22302, and 22336 ZIP codes call us back because the price on the phone matches the price on the invoice. No bait coupons, no upsells at the door. The 90-Day Done Right Promise is stamped on every job, and Ray Castillo stands behind it personally. If the work is not right, we return at no charge. No paperwork, no arguing.
Calls are answered by a live person, not a voicemail tree. That matters when you’re staring at mold in a vent on a Saturday evening or when your Del Ray bungalow’s airflow drops to nothing in August humidity.
Our Air Duct Cleaning Services in Alexandria
Residential Duct Cleaning
Alexandria’s housing stock is older than most of Northern Virginia, and that age shows in the ductwork. In Old Town’s 18th-century Federal-style brick row houses and Del Ray’s 1920s-1940s craftsman bungalows, forced-air HVAC was often retrofitted during the 1970s-1980s energy crisis. Contractors ran flex duct through rubble-stone crawl spaces, tight attic kneewall cavities, and masonry wall chases never designed for air movement. These convoluted runs accumulate debris far faster than purpose-built systems. Our residential cleaning addresses this with flexible-access equipment that suburban tract-home jobs rarely demand. A typical residential duct cleaning in Alexandria runs $320-$480 for a single-system home, with full-system jobs reaching $520-$580 for larger properties or homes with multiple returns.

Commercial Duct Cleaning
Commercial properties in Eisenhower Valley, the Route 1 corridor, and along the waterfront face Alexandria’s persistent summer humidity, which regularly exceeds 80% near the Potomac. That moisture promotes condensation inside supply ducts during cooling season, creating conditions for mold colonization that makes routine cleaning a health-driven necessity rather than a discretionary service. We clean office HVAC systems, retail spaces, and multi-unit buildings with the same upfront pricing and camera verification we provide homeowners. Commercial duct cleaning in Alexandria typically ranges from $680-$1,200 depending on system size and accessibility.

Supply Duct Cleaning
Supply ducts carry conditioned air to your rooms, and in Alexandria they’re often the first place moisture damage appears. The salt-laden air from the Potomac accelerates corrosion at joints and seams, while the city’s high summer humidity drives condensation that pools in low spots. In 1970s-1980s retrofit ductwork, uninsulated flex duct sags and collects dust at these low points, blocking airflow and creating breeding grounds for mold. We scope supply lines with video inspection before cleaning, so you see exactly what we’re addressing. Supply duct cleaning as a standalone service in Alexandria runs $180-$290.

Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and in Alexandria’s older homes they’re often the most compromised part of the system. In Old Town’s 19th-century brick townhomes, contractors frequently ran flex duct horizontally through original rubble-stone or brick crawl spaces with clearances under 18 inches. These sections are nearly inaccessible to standard rotary-brush equipment and become pockets of standing debris and mold that homeowners have no way to inspect themselves. In an Old Town 1870s row house on Prince Street, we unclogged a 120-year-old rubble-stone crawl space with a flex-duct run that had collapsed under its own debris. Using our Rotobrush with a 1.5-inch-diameter head, we scoped and cleaned a horizontal return that no standard brush could reach, removing 20 pounds of rodent nesting and mold that had been recirculating through the home for decades. Return duct cleaning in Alexandria typically costs $200-$340.

Full System Cleaning
For homes with comprehensive buildup or systems that haven’t been serviced in years, we recommend full system cleaning that covers supplies, returns, trunk lines, and the air handler. This is particularly important in Alexandria’s 22306 ZIP code and similar postwar neighborhoods, where 1970s ranch-style homes often contain flex duct now well past typical service life. Full system cleaning in Alexandria runs $480-$580 for most residential properties, and includes before-and-after video documentation.

Video Inspection
Every job we perform includes camera inspection of the ductwork before and after work begins. In Alexandria’s historic homes, this isn’t a luxury, it’s essential. You cannot see what lies inside a rubble-stone chase or a collapsed flex run without sending a camera through. We use Nikro and Rotobrush inspection systems to provide a visual record, not just a claim. Video inspection as a standalone diagnostic service costs $140-$180, and is credited toward any cleaning work you authorize.

Trusted Brands We Service in Alexandria
We clean and service ductwork connected to equipment from Honeywell, Aprilaire, and Nikro, among others. These are the same brands serious HVAC contractors specify, and we maintain relationships with regional distributors to source replacement parts without the delays that leave Alexandria homeowners waiting. Our Rotobrush and Nikro cleaning equipment is sized for the tight access points that historic homes demand, not just the open basements of new construction. When a Del Ray bungalow needs a plenum replaced or an Old Town row house requires a custom transition fitting, we don’t improvise. We specify the right part, show you why it matters, and install it correctly. Most parts orders for Alexandria customers arrive within 24-48 hours, keeping single-visit completion rates high.
Common Air Duct Cleaning Problems We See in Alexandria Homes
- Collapsed flex duct in prewar crawl spaces. In Old Town and Del Ray, flex duct runs through rubble-stone or brick crawl spaces with under 18 inches of clearance often collapse under accumulated debris weight, blocking airflow entirely and creating stagnant zones where mold colonizes unchecked.
- Moisture-driven mold in supply lines. Alexandria’s Potomac waterfront location means summer ambient humidity regularly exceeds 80% in neighborhoods like Eisenhower Valley and the Route 1 corridor. That moisture condenses inside cool supply ducts, creating conditions where mold establishes within a single cooling season.
- Sagging uninsulated flex duct from 1970s-1980s retrofits. Del Ray bungalows and postwar ranches in the 22306 area often contain flex duct installed during the energy crisis with inadequate support and no insulation. Low points collect dust and debris, restricting airflow and forcing HVAC systems to run longer and harder.
- Salt-air corrosion at duct seams and hardware. Alexandria’s tidal Potomac location means salt-laden air accelerates corrosion of metal duct seams, hangers, and fasteners. In homes within a few blocks of the waterfront, we’ve found galvanized hardware degraded to failure points that inland suburbs like Burke or Springfield wouldn’t see for years longer.

FAQs - Air Duct Cleaning in Alexandria
Every 2-3 years, and annually if anyone in the home has allergies or respiratory conditions. The rubble-stone crawl spaces and masonry chases in Old Town’s pre-1950 housing create debris accumulation patterns that purpose-built systems don’t experience, and the tight clearances mean problems compound faster once they start. Call (844) 685-6342 for a free video inspection and we’ll show you exactly what your system looks like inside.
Yes, salt-laden air from the Potomac accelerates corrosion of garage-door springs, hinges, and opener chains, often requiring replacement 3-5 years sooner than in inland suburbs like Burke or Springfield. We handle this with galvanized or coated springs, stainless hardware, nylon rollers, and corrosion inspections as part of our maintenance protocol. If you’re seeing rust on visible hardware, the components you can’t see are likely worse. Call for an inspection.
Yes. Our Rotobrush systems include 1.5-inch-diameter heads and flexible shafts designed for clearances under 18 inches, which is the standard constraint in Old Town’s rubble-stone and brick crawl spaces. Standard rotary brushes cannot navigate these runs, and equipment that can’t reach the debris can’t remove it. We verify access with video inspection before quoting, so you’ll know what’s possible before we start.
Yes, full system cleaning is our standard recommendation for 22306 ranch-style homes with original flex duct. The uninsulated flex installed during the 1970s-1980s retrofit period has typically sagged at low points and accumulated debris at joints that are now past service life. Our full system cleaning includes supplies, returns, trunk lines, and air handler, with before-and-after video. Typical cost for a 22306 ranch is $420-$520. Call (844) 685-6342 for a free estimate.
Yes, we clean aging flex duct with controlled suction and soft-bristle systems that remove mold and debris without tearing brittle material. However, we will also show you camera evidence of any sections where the flex has degraded beyond safe cleaning, because 1980s flex duct in Alexandria’s humid climate often reaches end-of-life while still technically intact. If replacement is needed, we quote it upfront with no pressure. The $89 Seasonal Tune-Up includes a basic duct assessment if you’re unsure where to start.
