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.
Fast, Reliable Air Duct Cleaning Across Alexandria
Air duct cleaning in Alexandria, VA typically costs $425 – $875 for a complete residential system, and what you’re really paying for is source removal, not a vent-count pitch. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we work throughout Alexandria’s rowhouse corridors and single-family neighborhoods weekly. Our crews know Old Town’s 19th-century chases, the 1950s duct retrofits in Seminary Hill, and the sprawling split-levels off Kingstowne just as well as we know our equipment. Call (737) 727-2314 and you’ll get a live person, a written price before any work starts, and before-and-after photos of your own ducts.
Why Cardinal Air Duct Cleaning Is Alexandria’s Preferred Air Duct Cleaning Company
Alexandria homeowners keep our schedule full for two reasons: we tell the truth about when duct cleaning is worth it, and we charge one flat price per system that doesn’t shift once the van is parked. That second part matters here more than most cities. Alexandria’s housing stock ranges from 200-year-old brick rowhouses with gravity-furnace chases to 1990s colonials with flex duct in the attic, and a per-vent quote doesn’t describe the work accurately for either one.
Every job we do in Alexandria runs on the same Relay Standard: a live trackable arrival window, background-checked technicians in uniform, and a digital invoice you can pay from your phone. Omar Haddad owns this Cardinal location and holds every crew to that standard. If the work isn’t done right within 365 days, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it covers every booking without exception.
Response time to Alexandria from our Washington, DC scheduling office is straightforward: we book within a window you can see, not a four-hour guess. Most Alexandria jobs are completed in three to six hours, depending on system size and how much source material we’re pulling. For a closer look at our process, see our Air Duct Cleaning service hub.
HVAC Duct Cleaning in Alexandria
HVAC Duct Cleaning in Alexandria means cleaning the full path your conditioned air travels, supply and return sides both, with HEPA-filtered negative pressure so loosened debris goes into the vacuum and not back through your living room. In Alexandria specifically, this job is half cleaning and half discovery. The original duct routing in many pre-1950 homes was retrofitted for central air decades after it was built, and the runs are often short, kinked, and hidden behind plaster rather than behind modern access panels.
Supply and Return Runs
We clean supply ducts from the plenum to the register and return ducts from the grille back to the air handler, using a Rotobrush rotary brush system paired with Abatement Technologies containment. On some Old Town runs, the actual duct is only eleven feet long but turns twice and necks down from 8 inches to 6. We treat that as its own job, not a standard “12 vents, 20 feet each” formula.
Video Inspection Before We Quote
Before you pay anything, we camera the trunk line and branch runs. This matters in Alexandria because the quote should reflect what’s actually hiding in the chase, not a generic assumption. A cleaning-only job where the duct is intact runs $425 – $650 for a typical Alexandria rowhouse. Add source removal from a compromised return and you’re in the $650 – $875 range. That’s the price you get in writing before work begins.
Vent Cleaning in Alexandria
Vent Cleaning in Alexandria, done correctly, is not scrubbing the register covers and calling it a day. It is cleaning the full interior of the ducting connected to those registers, plus the register itself. In Alexandria’s older homes especially, the vent cover may only be the visible end of a short branch line that connects to an open joist bay or an unlined masonry chase. That’s where the dust, pet hair, and rodent debris is, not behind the decorative grille.
Supply Registers and Source Removal
We brush and vacuum every supply run back to the trunk, then clean the register and reseat it. If the run opens into a cavity, which we find regularly in Del Ray and Rosemont homes from the 1920s and 1930s, we set negative pressure and agitate the source material out of the pocket. That’s the difference between a visible vent cleaning and a real one.
Return Grilles and the Hidden Side
Return vent cleaning in Alexandria often reveals the real problem: a return that draws air through a wall cavity instead of a sealed duct. We seal those paths once the debris is removed so the return is pulling air from the conditioned space, not the crawlspace. Typical vent cleaning for a rowhouse in Alexandria runs $300 – $450 when it’s tied to a full system cleaning, and we quote it as part of the flat system price, never per vent.
Trusted Brands We Service in Alexandria
Alexandria is loyal to its equipment brands, and we service all of them. We regularly clean systems tied to Honeywell air cleaners, Aprilaire filters, and Nikro-certified vacuum extraction setups. When your Aprilaire media housing or Honeywell bypass filter is saturated, the duct cleaning won’t hold, so we stock common replacement media and include filter inspection in every Alexandria job. No separate trip, no surprise line item. Fast turnaround on parts means we’re not waiting a week to finish your system.
Common Air Duct Cleaning Problems We See in Alexandria Homes
- Original 19th-century gravity-furnace chases left open to the crawlspace. In Old Town and Parker-Gray, the original furnace used an open chase, and when central air was added, the return path sometimes never got sealed. That pulls crawlspace air, lint, and mouse debris into your supply every time the fan runs.
- Discontinuous return paths in rowhouse party walls. We use camera inspection on homes along King Street and Duke Street because a return that should be a single run is often three segments joined by a joist bay. A brush won’t clean a joist bay; negative pressure and agitation will.
- Kinked flex duct in attic retrofits. Many 1950s and 1960s split-levels and ramblers in the Alexandria section of the West End were retrofitted with flex duct that now kinks at the plenum collar. That kink catches debris and chokes airflow, and it needs cleaning plus re-hanging, not just vacuuming.
- Oversized systems blowing through undersized ducts. When a 3-ton condenser was paired with 1940s trunk sizing in the Del Ray and Rosemont housing stock, the velocity keeps fine dust suspended. Cleaning helps, but sealing and airflow correction is the real fix, and we’ll tell you that honestly.

FAQs About Air Duct Cleaning in Alexandria
Every 3 to 5 years for most Alexandria rowhouses, but only if you have pets, had renovation work, or can see dust buildup at the registers. If your system was retrofitted for central air in the last 10 years and you change filters regularly, you might honestly not need it. Call (737) 727-2314 and ask for an inspection first; if the ducts are clean, we’ll tell you not to spend the money.
Per system, always. We quote one flat price for your entire duct system before any work starts, and it does not change at the door. Per-vent pricing punishes Alexandria rowhouse owners whose real problem is a single shared return chase, not a dozen supply registers.
Yes, before-and-after photos are standard on every job, not an upsell. You’ll see the camera feed and the extracted debris, so you know what we found and what we removed. That’s part of The Relay Visibility Guarantee, and it applies to every Alexandria booking.
If your ducts are under 10 years old, you’ve changed filters on schedule, and there’s no visible dust or odor at the registers, you probably don’t need cleaning. If you have a persistent musty smell on the second floor of an Old Town rowhouse, that’s a return chase issue and cleaning is absolutely worth it. We’ll inspect first and tell you straight.
No, and we don’t pretend otherwise. Duct cleaning in Alexandria is a scheduled job that takes three to six hours on site, and we book within a live trackable arrival window you can see on your phone. Same-day claimers in this trade tend to rush the work; we don’t. Call (737) 727-2314 to schedule and get your written price.
