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.

Call (571) 487-7204 for a free estimate.
We’re not a Carrier dealer or authorized service center. We’re an independent Leesburg Carrier service provider that has worked on enough of these systems here to know where they trap debris and where they leak. Leesburg sits at the edge where Loudoun County’s agricultural Piedmont meets suburban expansion, and Carrier systems here pull in a heavy load of hay dust, pollen off the Blue Ridge, and construction debris from 2000s-era builds that have never been cleaned. That combination produces contamination patterns we can predict before we open the first register.
Tomas Reyes, our owner, grew up in Queens and learned the trade at Triangle Tech in New York. He’s spent the better part of two decades working HVAC and duct systems up and down the East Coast. The camera goes in before the quote comes out. That’s the principle he built CleanRun on in 2013, and it’s still how we operate on every Carrier job in Leesburg.
Why Trust CleanRun Air Duct Cleaning Leesburg for Your Carrier Air Duct Cleaning?
Carrier builds its air handlers and coils with specific cabinet geometries that trap debris differently than Lennox or Trane units. Our technicians know the N-coil evaporator assembly in Performance and Infinity systems collects lint on the underside of the coil, not the top, because of how Carrier routes return air. We’ve cleaned enough Carrier variable-speed blower wheels to recognize the particular hum an Infinity blower makes when dust buildup throws it out of balance. This isn’t brand loyalty. It’s pattern recognition from documented fieldwork.
We use OEM Carrier replacement parts for blower modules and coil assemblies when they’re available and make sense for the repair. For gaskets, mastic, and flex duct, we specify aftermarket products that meet or exceed OEM specs and save money without cutting corners. Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - brands you can look up yourself before you agree to any work.
Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. You’ll get the technician’s name before arrival. Every job carries the 365-Day Done Right Promise in writing, not as a verbal assurance. And every estimate is free, with a written price delivered before any panel comes off - Haven Standard Clause 1.
Common Carrier Air Duct Cleaning Problems We Fix in Leesburg
- N-coil lint accumulation in Performance and Infinity air handlers. Carrier’s N-coil design routes return air across the underside of the evaporator, which collects lint and dust where the homeowner can’t see it. The result is musty odors and reduced airflow that persists even after filter changes. We recently serviced a 2015 Carrier Infinity system in a Lansdowne-area townhome where the homeowner complained of exactly this - musty smell, weak second-floor airflow. Video inspection showed the N-coil matted with dust and the variable-speed blower wheel caked with lint. Full evaporator coil and blower cleaning, plus resealing the plenum with mastic, restored airflow at the farthest register and eliminated the odor.
- Pinhole tears and disconnected collars in factory-installed flex duct. Carrier systems installed during Leesburg’s 2000s building boom often came with foil-faced flexible duct runs that have now aged 15-20 years without service. The outer jacket degrades, collars pull loose at the plenum, and the system starts drawing attic or crawlspace air into the supply stream. In River Creek and Woodlea Manor, we routinely find original builder flex duct still holding drywall dust from rapid construction, now torn and leaking.
- Variable-speed blower motor imbalance from fine dust buildup. Infinity series blowers run at variable speeds for extended periods, which makes them efficient but also makes them prone to collecting fine dust on the blower wheel. The imbalance produces increased noise and can prematurely fail the ECM module. Cleaning the blower wheel during service prevents this. We check run capacitance and bearing wear while the assembly is out.
- Unsealed metal duct trunk seams leaking 20-30% of conditioned air. Carrier metal duct systems in 1990s-2000s Leesburg builds often have longitudinal seams and takeoffs that were never sealed at installation. The conditioned air leaks into unconditioned attic spaces before it reaches the registers. We seal with mastic and fiberglass mesh, not tape that will fail in Leesburg’s humid summers.
- Mold colonization in attic duct runs. Leesburg’s humid summers and the large two-story colonials common in Potomac Station create perfect conditions for mold inside ducts that pass through unconditioned attic space. Carrier systems with undersized returns or leaky flex connections pull in humid attic air, accelerating the problem. We document growth with photo evidence and clean with equipment appropriate to the contamination level.

AfterCarrier Parts & Our Repair-vs-Replace Approach
We stock OEM Carrier blower modules, coil assemblies, and control boards for fast turnaround on common failures. For consumables like gaskets, flex duct, and mastic, we use aftermarket products from trade-recognized manufacturers when they meet or exceed OEM specifications and reduce cost without reducing lifespan.
Our repair-vs-replace recommendation is straightforward. If your Carrier air handler or coil is under 12 years old and the cabinet is structurally sound, repair is usually the right call. If the heat exchanger is rusted through, the ECM blower has failed, or the coil has multiple refrigerant leaks, replacement may be more cost-effective over the remaining system life. We’ll show you the photo evidence and put both options in writing with a fixed price for each. No phantom problems. No inflated scope.

Our Carrier Service Process - Step by Step
- 1
Video diagnosis. We insert a borescope camera into every accessible duct run and photograph the evaporator coil, blower assembly, and plenum connections. You see what we see before any work is approved. This is standard on every visit, not an upsell.
- 2
Written scope and price. Based on the camera findings, we deliver a written scope with a fixed price for the complete job - coil cleaning, blower cleaning, duct sealing, or flex replacement as needed. Haven Standard Clause 1: no work begins without a written price.
- 3
Cleaning and repair. We perform negative-pressure extraction on the duct system, clean the evaporator coil and blower assembly with appropriate methods for Carrier’s fin spacing and cabinet design, and seal leaks with mastic. Damaged flex duct is replaced. Every step is photographed.
- 4
Post-service testing and documentation. We measure static pressure and airflow at key registers, deliver before-and-after photos of every duct run, and provide a written job record including the 365-Day Done Right Promise. If the work isn’t right, we make it right.
Carrier Products We Service & Install in Leesburg
We service and clean all Carrier residential lines common in Ashburn Carrier service areas and Leesburg homes: Performance series split systems (24ACC/24APS), Infinity series variable-speed systems (24ANB/25VNA), Comfort series entry-level units (24ABB/24ABC), and 58 series gas furnaces (58STA/58CVA). We stock replacement blower modules, coil assemblies, and control components for these series locally. For older Carrier systems still operating in Leesburg’s historic Old Town core, we assess access constraints and duct compatibility before recommending any work.
We Also Service These Brands
CleanRun is not limited to Carrier. Our technicians are equally familiar with Lennox and Trane cabinet designs, coil configurations, and failure modes. Multi-brand capability means our diagnostics are based on what the system actually needs, not what a single-brand script recommends.
FAQs - Carrier Air Duct Cleaning Service in Leesburg
The N-coil evaporator assembly in Carrier Infinity and Performance air handlers collects lint and dust on the underside of the coil, where the filter doesn’t reach. This debris traps moisture and produces musty odors that circulate through the supply ducts. A filter change won’t fix it because the contamination is downstream of the filter rack. The solution is evaporator coil cleaning and blower wheel cleaning, which we perform with the cabinet opened and the coil accessed properly. Call (571) 487-7204 for a free estimate - we’ll show you the camera footage first.
No. We are an independent Carrier service provider, not a Carrier dealer or authorized service center. We have no affiliation with Carrier Corporation. Our expertise comes from documented field experience on thousands of Carrier systems, including Carrier repair in Sterling, Leesburg and Loudoun County, not from manufacturer certification.
Proper duct cleaning performed by qualified technicians will not void your Carrier warranty. Warranty issues arise only when unqualified work damages components - using excessive pressure on coils, improper chemical application, or forcing access panels. Our technicians follow manufacturer-access guidelines for Carrier cabinet designs and document every step. If your system is still under warranty, we note the service in writing for your records.
In Leesburg’s conditions - heavy spring pollen from the Blue Ridge, agricultural particulates from surrounding farmland, and humid summers that promote dust adhesion - we recommend blower wheel inspection every 3-4 years and cleaning when video inspection shows buildup. Infinity and Performance variable-speed blowers run longer at lower speeds than single-stage blowers, so they collect more fine dust over time. Waiting until you hear noise or smell odor means the motor is already working harder than it should. Call (571) 487-7204 to schedule a camera inspection and we’ll tell you exactly what your blower looks like.
Yes. Carrier metal duct trunks installed in Leesburg homes built from the 1990s through the 2000s typically have unsealed longitudinal seams and takeoff connections. We’ve measured leakage rates of 20-30% in these systems, which means you’re conditioning your attic instead of your bedrooms. We seal with mastic and fiberglass mesh, not duct tape, because tape fails within a few years in Leesburg’s humidity. The work is photographed before and after, and the energy savings usually recover the cost within two to three heating and cooling seasons.
It depends on what the camera finds. If your ducts are heavily contaminated or leaking, cleaning and sealing will reduce blower workload and improve delivered airflow, which reduces runtime and energy use. If the ducts are relatively clean but the coil is fouled, coil cleaning produces the efficiency gain. We don’t sell duct cleaning as a universal efficiency fix. We diagnose first, show you the evidence, and recommend the specific service that matches what your Carrier system actually needs.
