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.

AfterWhy a Brand-New Leesburg House Often Has Dirty Ducts
If you bought a colonial in Lansdowne, River Creek, or Potomac Station built between 1995 and 2010, there’s a good chance your HVAC system has been pulling construction debris through its ductwork since the day the Certificate of Occupancy was signed. Builders do not clean ducts at handover. Drywall dust, sawdust, and scraps of flex duct end up sealed inside the system, and in a 3,000-4,500-square-foot multi-zone colonial with extensive attic runs, that’s a lot of material. An HVAC cleaning in Leesburg on one of these homes typically runs $450-$850 for a full system, depending on the number of zones and whether the evaporator coil and air handler need the deeper work they usually do. Call (806) 606-6902 to get a written price for your specific floor plan.
What HVAC Cleaning in Leesburg Actually Involves
Most homeowners have never seen the inside of their own ductwork. That’s the problem. When our HVAC Cleaning crew arrives at a Leesburg property, the first thing we do is run a camera through the supply and return runs, the plenum, and the air handler. Then we show you what’s there. In a 2006 River Creek colonial, we found drywall dust from the original build caked so thick on the supply runs that the blower motor was pushing against a 40% airflow restriction. That’s not unusual for this housing stock. We knocked the crust loose with Rotobrush agitation tools under negative-pressure extraction, then HEPA-vacuumed the air handler and coated the evaporator coil. The homeowner told us the system hadn’t run that quietly since move-in day.
That’s what a documented job looks like. Every duct run is photographed before and after, and the photo record is delivered to you as part of the standard job file. No exceptions. That practice has been in place since our first job in 2013.
How Much Does HVAC Cleaning Cost in Leesburg, VA?

BeforeAfterWhy Leesburg’s Climate Loads Ducts Faster Than You’d Expect
Leesburg sits at the base of Loudoun County’s horse-farm belt. The town is ringed by active equestrian properties on multiple sides, and the Piedmont’s prevailing airflow pushes a steady stream of fine hay dust, dander, and agricultural particulates into the outdoor air your HVAC system pulls inside. Homeowners who moved here from denser Northern Virginia suburbs like Ashburn or Sterling are often surprised by what they see in our camera inspections. Technicians working the west Leesburg fringe near Raspberry Falls, Selma Estates, and Route 15 north routinely pull ducts packed with fine organic debris that you simply don’t see east of the Greenway.
Then there’s the humidity. High-80s percent relative humidity is normal in a Leesburg summer. When that air moves through unconditioned attic duct runs, which is exactly how most 1995-2010 colonials here are built, condensation forms. Dust plus moisture is how mold colonizes inside ductwork. This is a real, documented pattern in the Lansdowne, River Creek, and Potomac Station housing stock. Not every system has it. But enough do that we recommend camera verification on any Leesburg home that hasn’t been cleaned since construction.
Our HVAC Cleaning Services in Leesburg
Evaporator Coil Cleaning
The evaporator coil is the single most neglected component in Leesburg’s HVAC systems, and it’s the one that costs you the most when it’s dirty. A fouled coil forces the compressor to run longer to hit the same set point. On a three-zone colonial in River Creek, that’s hundreds of dollars a season in wasted energy. We remove the coil access panel, photograph the before state, apply a professional coil treatment appropriate to the material, and document the result. Expect $180-$320 for this service depending on coil accessibility.
Air Handler Cleaning
Your air handler is where the blower pulls air through the filter and pushes it into the duct runs. In Leesburg’s builder-grade colonials, the blower wheel, housing, and motor get coated with construction dust and, over time, the fine particulate load from the surrounding agricultural land. We pull the blower assembly, HEPA-vacuum the housing, clean the blower wheel, and reassemble. You’ll hear the difference. A River Creek homeowner told us the system was quieter after our air handler cleaning than it had been on the day he got the keys. That’s not a brag. That’s the job, done correctly.
Blower Cleaning
A blower wheel caked with dust and debris is out of balance. That means vibration, bearing wear, and eventually a motor replacement that costs several times what a cleaning does. Our blower cleaning pulls the wheel, removes the crust, and documents the before and after. On the 40% airflow restriction job we mentioned earlier, the blower motor was pulling more amps than spec. After the cleaning, the amp draw dropped back into normal range. The homeowner’s electric bill came down with it.
Condenser Cleaning
The outdoor condenser unit deals with everything Leesburg’s air throws at it: pollen, cottonwood fluff, horse-farm dust, grass clippings. A clogged condenser coil is the single fastest way to kill a compressor. We clean the coil with professional-grade equipment, clear the surrounding debris, and check the refrigerant lines. This runs $120-$200 and should be done every one to two years on properties near agricultural land.

What We Find in Leesburg Ductwork That Generic Cleaners Miss
- Construction debris sealed in from the build: Drywall dust, sawdust, and debris from the 1995-2010 building boom is still inside the duct runs of thousands of Leesburg homes. Builders don’t clean at handover. The first cleaning often happens five, ten, or twenty years later.
- Builder-grade flex duct sagging and separating in unconditioned attics: The attic heat in a Leesburg summer is brutal on flex duct. Joints separate, and the system starts pulling unfiltered attic air, which means insulation fibers and whatever else is up there ends up inside your ducts and inside your house.
- Multi-zone dampers stuck open or closed from construction debris: This is the one that leads homeowners to call an HVAC repair company and get quoted a new thermostat, a new control board, or even a new system. Often it’s just debris in the damper mechanism. We see it constantly in River Creek and Potomac Station multi-zone homes.
- Return-air chases that were never sealed at framing: The return path in a 1990s colonial was often an open cavity between studs, not a sealed duct. That means attic dust, insulation fibers, and horse-farm particulates bypass the filter entirely and re-contaminate the system within months of a cleaning. We identify this during the camera inspection and tell you exactly what’s going on.
Why a New House Needs an HVAC Cleaning Sooner Than You’d Think
The core insight for Leesburg specifically is this: the town’s housing stock is young, and the dirt is old. A 2006 colonial in Lansdowne has spent nearly two decades circulating air through ducts that were dirty on day one. The drywall dust from construction, the debris dropped in during the build, the flex duct fragments, all of it. And because these homes are large, with multi-zone systems and extensive attic runs, the volume of ductwork is substantial. A proper NADCA source removal on a 4,000-square-foot multi-zone colonial means cleaning every supply and return run to the register, the plenum, the air handler, the blower, and the evaporator coil. That’s not a two-hour shop-vac job. That’s a documented, photographed, half-day to full-day process depending on the system.
We pulled a camera through a River Creek colonial where the supply and return ducts still held drywall dust from the 2004 build. The blower was laboring against a 40% airflow restriction. Our Rotobrush tools knocked the crust loose under negative pressure, we HEPA-vacuumed the air handler, and we coated the evaporator coil. The system ran quieter than the homeowner had ever heard it. That’s the before and after we deliver on every job, in photos, not in words.

FAQs - HVAC Cleaning in Leesburg
Because construction dust was sealed into the ductwork before you ever got the keys. Builders do not clean ducts at handover. Drywall dust, sawdust, and flex duct fragments from the original build stay inside the system, and every time the blower runs, it recirculates that material. Your house was new, but the ducts were dirty from day one. A camera inspection will show you exactly what’s in there. Call (806) 606-6902 and we’ll set it up.
Yes. The town sits at the base of Loudoun County’s equestrian belt, and the Piedmont’s prevailing airflow carries fine hay dust and dander across the entire area. Properties near the rural-urban edge, like Selma Estates or the Route 15 corridor, see the heaviest loading. But Potomac Station and the other subdivisions west of Battlefield get a measurable particulate load that shows up clearly in camera inspections and filter change intervals. Homeowners who moved from Ashburn or Sterling consistently tell us they’ve never seen filters load up this fast.
The symptom is straightforward: one floor stays hot while another stays cold, and the thermostat readings don’t match the actual room temperatures. You might also hear a faint clicking or grinding from the damper motors as they try to move a stuck blade. Many HVAC companies will quote you a new zone control board before checking the dampers. We check the dampers first. Camera inspection takes that guesswork out of the diagnosis. If the dampers are caked with construction debris, that’s a cleaning job, not a replacement.
Cleaning is the first step, and for most systems it’s enough. The camera inspection tells us the real answer. If the flex duct has sagged, separated at joints, or collapsed, cleaning won’t fix those structural problems. But we don’t quote replacement until we’ve documented the damage and shown it to you. Our techs are trained under the H.A.V.E.N. Standard to report what the camera sees, not what generates the biggest invoice. In many 20-year-old attic systems, the duct body is sound and a proper NADCA source removal restores full airflow.
Source removal means the debris is physically removed from the ductwork, not just loosened or sprayed over. We run agitation tools through every supply and return run under negative pressure, so the dust and construction debris are pulled out of the system and into our HEPA filtration, not blown back into your house. For a two-story Potomac Station colonial with a multi-zone air handler, that means the plenum, both zone runs, the return chases, and the air handler itself all get the same documented treatment. The photo record shows the before and after in every run, not just a sample. Pricing for that scope typically falls in the $650-$850 range depending on zone count and access.
