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.

AfterLennox Air Duct Cleaning in Arlington, DC | CleanRun Air Duct Cleaning Washington
We provide our Air Duct Cleaning in Arlington for independent Lennox service across mid-century multifamily buildings, from original heat pumps to modern variable-speed air handlers. The one thing that makes our Lennox work here different: Arlington’s concentration of 1940s-1960s garden apartments with aging internal duct liner creates failure modes we don’t see across the county line in Fairfax, and we address them with video inspection before any cleaning begins. Call (240) 363-3380 for a written estimate before any work starts.
Why Arlington Residents Choose Us for Lennox Service
Tomas Reyes, our owner and lead technician, grew up in the Bronx working summers alongside his uncle repairing commercial HVAC units for apartment buildings. He trained in HVAC and sheet metal fabrication at Bronx Community College, then spent years doing duct and ventilation work across the mid-Atlantic before settling our operation into the Washington, DC market. Over more than two decades in air duct cleaning, Tomas has become the technician other technicians call when a job involves unusual duct configurations - the kind of gravity-fed systems and undersized flex runs that show up regularly in DC’s older housing stock.
We’re independent specialists, not a Lennox-authorized dealer. That matters in Arlington because we can tell you honestly when your problem is the ductwork, not the equipment, without a manufacturer’s warranty agenda steering the diagnosis. We work on Lennox systems daily - Merit Series furnaces in 1990s Courthouse renovations, Elite Series variable-speed handlers in Ballston high-rises, Dave Lennox Signature Collection units in Lyon Village teardown rebuilds. Our crews carry OEM-equivalent Lennox-compatible blower wheels, limit switches, and flex-duct connectors, plus aftermarket filters and mastic sealants that meet or exceed OEM specs. Every job starts with a written price under Haven Standard Clause 1 and ends with a Documented Photo Record of every duct run, before and after.
Our Lennox sales & service page covers our full brand capabilities, but this page is specific to what Arlington buildings do to these systems.
Common Lennox Air Duct Cleaning Problems We Solve in Arlington
- Internal fibrous duct liner shedding from 1950s-60s Lennox air-handler supply plenums. The original liner flakes into the airstream and coats the blower wheel and evaporator coil. We see this constantly in Columbia Pike garden apartments where the liner has reached end of life after 60-plus years. Our approach: video inspection first, then liner-condition assessment before any agitation cleaning.
- Blower wheel imbalance and motor overload on Lennox variable-speed air handlers. Lint and degraded liner fibers collect in return-air systems of Columbia Pike garden apartments, throwing the blower off balance and stressing the variable-speed module. We remove and clean the wheel, inspect the module for heat damage, and document static pressure before and after.
- Evaporator coil fouling on Lennox high-efficiency systems. Arlington’s humid summers - sustained heat-index values above 100°F - keep AC running hard for months. Condensation mixed with heavy spring oak pollen creates microbial growth that restricts airflow and raises static pressure. We treat the coil with antimicrobial and verify airflow recovery with a manometer.
- Flex-duct collapse and disconnection at Lennox air-handler connections. Post-1979 high-rises near Ballston and Clarendon run flex through concrete chases where kinking and pest damage are common. We inspect with a borescope, replace damaged sections with new flex rated for the application, and seal with mastic, not tape.
- Gravity-fed return systems pulling debris from deteriorating masonry chases. Unique to Arlington’s older multifamily stock: returns run through unlined concrete or brick, and the negative pressure draws fine masonry dust into Lennox air handlers. We seal accessible chase openings and install proper return-air filtration.
BeforeAfterLennox Service in Arlington: What Local Conditions Mean for Your Equipment
Arlington’s Columbia Pike corridor has the highest concentration of 1940s-1960s garden apartments in the region, and their centralized Lennox air-handling units often sit in concrete mechanical closets with duct runs embedded in masonry - a layout that requires video inspection before any cleaning because liner debris can be trapped in horizontal runs that are invisible from the unit. This isn’t a suburban attic job where you pop a panel and see everything. The ductwork is structural, original to the building, and often inaccessible without a borescope and a plan for how to extract debris without pushing it deeper into embedded runs.
We were called to a 1962 garden apartment off Columbia Pike near Glebe Road where the resident complained of fiberglass particles on furniture and a musty smell from the Lennox air handler. After a video inspection, we found the original internal duct liner crumbling inside the supply trunk and coating the blower wheel; we performed a full-system cleaning with liner-condition assessment, replaced the damaged flex run to the kitchen, and sealed the plenum with mastic. The Lennox air handler was then cleaned and the evaporator coil treated, restoring airflow and eliminating the debris at the registers. “Show the before photo first. Everything else follows from that.” The resident had the photo record in her inbox before we packed the truck.
That job illustrates why we don’t quote Lennox duct cleaning in Arlington without a preliminary inspection. The scope changes based on what the camera finds, and the camera finds things in these buildings that don’t exist in Fairfax’s 1990s subdivisions.
Lennox Models & Products We Service in Arlington
We clean and service the full range of Lennox residential equipment found in Arlington’s housing stock:
- Merit Series gas furnaces and air handlers - common in 1990s-2000s Arlington renovations, often paired with builder-grade ductwork that needs sealing and balancing
- Elite Series variable-speed air handlers and heat pumps - found in newer garden apartment conversions and some Ballston high-rises; the variable-speed modules are sensitive to airflow restriction from dirty ducts
- Dave Lennox Signature Collection (SL280V, EL296V) - high-efficiency furnaces in upscale Lyon Village and Ashton Heights rebuilds; these require precise static pressure after any duct modification
- 14 SEER and 16 SEER heat pump systems - standard in older Arlington garden apartments where the original Lennox air handler has been replaced but the ductwork hasn’t
We stock OEM-equivalent parts locally for fast turnaround on Arlington jobs. If your Lennox air handler is over 12-15 years old with a cracked heat exchanger or failed variable-speed module, we’ll tell you plainly when repair no longer makes financial sense. No replacement pressure - just the condition of your system, documented with photos.
Lennox Service Pricing in Arlington
Lennox air duct cleaning in Arlington typically runs $380-$620 for a complete system, depending on access complexity, duct run count, and whether video inspection reveals liner degradation requiring additional scope. A standard job includes negative-pressure extraction (suction that pulls debris out while containing it), register and return cleaning, air handler and blower wheel service, evaporator coil inspection, and the Documented Photo Record delivered to you.
Factors that increase cost in Arlington: embedded duct runs requiring borescope navigation, liner debris requiring HEPA containment, flex-duct replacement in concrete chases, and coil treatment for microbial fouling. We deliver a written price before any work starts, every time, under Haven Standard Clause 1. No per-vent pricing, no coupon bait-and-switch. Bring a competitor’s written estimate and we’ll provide a Free Second Opinion, our number next to theirs.

FAQs - Lennox Air Duct Cleaning in Arlington
Yes, but we video inspect first. Original ductwork in 1990s Arlington garden apartments is typically galvanized steel with possible internal liner degradation. We use low-RPM rotary brushes and controlled negative pressure rather than high-speed agitation, and we stop the moment the camera shows liner separation. The photo record lets you see exactly what we found and what we did. Call (240) 363-3380 for a written estimate - inspections are free.
Arlington’s sustained summer humidity - heat-index values above 100°F for weeks - creates condensation on the evaporator coil and inside duct runs. Mixed with oak pollen and dust, this grows microbial biofilm that releases odor when the system cycles. We clean the coil with antimicrobial treatment, verify condensate drainage, and inspect the plenum for standing water. The smell returns if the underlying moisture issue isn’t addressed. Call (240) 363-3380 and we’ll scope it.
Yes, significantly more. Arlington’s garden apartment stock along Columbia Pike and near Metro stations was built with fibrous internal duct liner that is now 60-plus years old. Fairfax’s dominant housing is 1980s-2000s single-family with unlined metal duct or newer flex - the liner failure mode barely exists there. In Arlington, we assess liner condition on every pre-1970 job. It’s a different category of work.
Possibly. Rattling from a Lennox heat pump often indicates blower wheel imbalance from debris accumulation, or flex-duct vibration where a connection has loosened in the concrete chase. We inspect the wheel and duct connections with a borescope; if the noise is mechanical (bad bearing, failing motor), we’ll tell you that too. Our written estimate separates cleaning scope from repair so you know exactly what you’re paying for. Call (240) 363-3380 to schedule.
We can clean and, in many cases, reroute Dryer Vent Cleaning - Arlington condos, including those sharing mechanical space with Lennox air handlers. Condo dryer vents often run through the same concrete chases as HVAC ductwork, creating lint accumulation and fire risk. We inspect with a camera, remove blockages with rotary tools, and replace damaged sections to code. If rerouting requires structural modification, we coordinate with your building’s management. Call (240) 363-3380 for a written scope and price.
