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.

AfterFast, Reliable HVAC Cleaning Across Alexandria
HVAC cleaning in Alexandria, VA typically costs $425-$780 for a full system on a single-family home, with coil cleaning running $180-$320 and blower cleaning $150-$275 as standalone jobs. The price depends on what our camera finds once we open the system, and in Alexandria, what we find is rarely standard. Older duct geometry, retrofit work, and river humidity change the job. We’ve spent years working Old Town rowhouses, Del Ray bungalows, and West End garden apartments, and we know what accumulates inside these systems that a visual check never shows. Call (806) 606-6902 for a written price before any work begins.
Why CleanRun Air Duct Cleaning Is Alexandria’s Preferred HVAC Cleaning Company
Alexandria homeowners don’t call us because we’re the cheapest. They call because we document everything. Every HVAC Cleaning job here starts with a camera inspection of the duct runs, coil, and blower assembly, and ends with before-and-after photos of every register and plenum we touched. That’s the only way to prove the work happened, and in a city where some houses have 200-year-old walls hiding 1970s ductwork, proof matters.
Our technicians work under the H.A.V.E.N. Standard, which includes Clause 1: a written price before any panel comes off. No visit fee, no “we’ll see once we’re inside” pricing. Tomas Reyes, who leads our Alexandria crews, has spent years mapping the city’s odd duct configurations and knows the difference between a Del Ray bungalow’s crawl-space retrofit and an Old Town rowhouse’s brick flue chase. The response time to most Alexandria neighborhoods is same-week, with scheduling coordinated from our Washington, DC metro office. Every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3.
Our HVAC Cleaning Services in Alexandria
Evaporator Coil Cleaning
Alexandria’s summer dew points sit above 70°F routinely, and your evaporator coil is where all that moisture condenses. In older Alexandria homes, the coil often sits in a plenum that was never designed for easy access, so it gets skipped for years. We clean coils with professional-grade cleaners and tools from manufacturers like Nikro and Abatement Technologies, then photograph the before and after. A typical evaporator coil cleaning in Alexandria runs $180-$320, depending on access and buildup. When the coil is clean, the system pulls moisture properly instead of blowing humid air back into the house.
Blower Cleaning
The blower wheel is what pushes conditioned air through your ducts, and in Alexandria we routinely find blowers caked with a gray paste of dust and condensed river humidity. That buildup throws the wheel out of balance and cuts airflow to upstairs bedrooms. Blower cleaning in Alexandria typically runs $150-$275 and includes pulling the assembly, cleaning the fins with the correct solvent, and lubricating the motor per manufacturer spec. We show you the blower before and after because the difference is usually dramatic.
Condenser Cleaning
Outdoor condenser coils in Alexandria contend with pollen, cottonwood, construction dust from the city’s continuous renovation cycle, and exhaust soot from heavy King Street traffic. A clogged condenser drives up head pressure and shortens compressor life. Condenser cleaning involves pulling the disconnect, washing the fins with a coil-safe cleaner, and checking refrigerant pressures. Most Alexandria condenser cleanings run $120-$200 for a standard residential unit. We use Guardsman coil tools and Abatement Technologies cleaning agents so the work holds up.
Air Handler Cleaning
Air handlers in Alexandria’s older homes are often tucked into closets, attics, or crawl spaces that were never meant to house mechanical equipment. We pull the access panels, clean the coil, drain pan, and blower, and check the condensate line for the algae and sludge that feeds on Alexandria’s humidity. Air handler cleaning runs $220-$380 in the Alexandria market, and we always document the drain line before and after because a clogged line is one of the most common causes of water damage we see in Del Ray and Rosemont basements.

BeforeAfterTrusted Brands We Service in Alexandria
We clean and service all major HVAC brands across Alexandria, including Honeywell and Aprilaire systems, plus the full range of carrier, Trane, Lennox, Rheem, and Goodman equipment. Because we’re based in the DC metro area, we keep common filters, belts, and condensate components in stock, which means fewer return trips to Alexandria when a part needs replacing. If you have specific filtration or electronic air cleaner components from Honeywell or Aprilaire, our techs can service those as part of a full system clean, not as a separate upsell. Every piece of equipment we use, from Rotobrush to Nikro to Abatement Technologies, is professional-grade and verifiable before we start.
Common HVAC Cleaning Problems We See in Alexandria Homes
- Compacted debris in retrofitted duct runs. Old Town rowhouses frequently have flex duct squeezed through brick chases and plaster walls, and turns are sharp. Debris packs into the bends, and standard vacuum-only cleaning can’t dislodge it. We use agitation tools with negative-pressure extraction to break it loose without collapsing the duct.
- Deteriorating fiberglass liner inside original sheet-metal ducts. West End garden apartments and 1960s tract homes often still have original ducts lined with degrading fiberglass. Aggressive cleaning can shred that liner and blow particles into living spaces. We inspect the liner with a camera before choosing the cleaning method.
- Mold blooms that return within months. In Del Ray bungalows and similar pre-1950 homes, retrofit ducts run through uninsulated crawl spaces. Condensation forms inside the metal, and mold takes hold. Cleaning helps, but if the duct isn’t resealed and re-insulated, the bloom returns by the following summer. We can do the sealing and insulation as part of the same visit.
- Soot infiltration from shared fireplace flues. In Old Town, we’ve found flex duct routed through original 18th-century brick flue chases, sometimes sharing the chase with an active fireplace flue. Soot works its way into the supply air. That’s not a scare tactic; we have photos from actual Alexandria jobs showing the inside of those chases.

FAQs - HVAC Cleaning in Alexandria
Appointments in Old Town typically run 90 minutes to two hours longer than comparable jobs in newer subdivisions because the duct geometry is non-standard. In many of these rowhouses, 1970s-era flex duct was routed through original 18th-century brick flue chases and plaster wall cavities. Our techs can’t rush the agitation process in those runs without risking collapse, and the camera inspection alone takes longer because there are more bends, more dead-end runs, and more access limitations. A standard negative-pressure rig can actually damage inaccessible flex duct, so we adjust our approach and pace for these homes. Call (806) 606-6902 to schedule a longer appointment window for an Old Town rowhouse.
Sometimes, but not always. The musty smell in Del Ray bungalows often comes from condensation inside retrofit ducts that run through uninsulated crawl spaces. Cleaning removes the existing mold and debris, but if the duct isn’t resealed and re-insulated, moisture will return and the smell will come back within months. We tell you before we start whether we think cleaning alone will solve the problem, based on what the camera shows. If sealing is needed, we quote it separately in writing and do it during the same visit when possible. Call (806) 606-6902 and we’ll diagnose the source, not just treat the symptom.
Yes, and we’ve documented it on camera in Old Town. Some rowhouses had 1970s flex duct routed through original 18th-century brick flue chases, and in some buildings that chase still houses an active fireplace flue. The flex duct is not sealed against the soot, so fine particulate from the fireplace migrates into the supply air. We’ve pulled registers in Old Town and found visible gray film on the back of vent covers, which the camera then traces to the shared chase. This is one reason our work includes a pre-inspection camera pass, not just a cleaning. Call (806) 606-6902 to have your ducts inspected for this specific issue.
Alexandria sits directly on the Potomac River in one of the most humid corridors of the mid-Atlantic. Summer dew points above 70°F mean cooling systems in Alexandria’s older homes often run for months with condensation present inside poorly vapor-sealed ductwork. Arlington and Fairfax get the same general climate, but Alexandria’s housing stock has far more pre-1950 construction and uninsulated crawl spaces, so the humidity has more places to cause problems. The result is a faster mold colonization rate inside ducts and a higher frequency of rust and corrosion on older metal runs. Our cleaning protocols account for this with drying-time checks and moisture readings before we finish the job.
Yes, if the wrong method is used. Original sheet-metal ducts from that era in Alexandria’s West End garden apartments are often lined with fiberglass insulation that has been deteriorating for decades. Aggressive source-removal tools can shred that liner, releasing fiberglass particles into the living space. We inspect the duct liner with a camera before selecting the cleaning method, and we adjust our approach if the liner is compromised. If the liner is too far gone, we’ll tell you in writing and quote a repair or re-lining option before proceeding. Call (806) 606-6902 to schedule an inspection that protects the integrity of your original ductwork.
