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.

We’re CleanRun Duct Repair & Cleaning, and we dispatch crews to Leesburg from our Washington, DC office.

Why Leesburg Homes Are Different
Leesburg sits where Loudoun County’s equestrian Piedmont meets suburban expansion, and that location changes what we find inside the ductwork. HVAC systems here pull in hay dust, agricultural particulates, and horse-related allergens from surrounding hunt-country farms, a contamination profile you won’t see in Ashburn or Sterling to the east.
The housing stock tells the rest of the story. River Creek, Woodlea Manor, and Potomac Station are packed with 3,000-5,000 square foot homes built during the 2000s boom, most with builder-grade flexible ductwork now hitting 15-20 years without a cleaning. In the historic Old Town core, pre-WWII and mid-century homes with rigid duct or converted heating systems present access challenges the planned communities don’t. Spring pollen loads off the Blue Ridge intensify at this elevation, and humid summers push mold growth in attic duct runs.
Our Main Leesburg Services
Most Leesburg homeowners who call us start with one of these three services.
Air Duct Cleaning in Leesburg
We clean the full duct network, registers, and return plenum, the main distribution box where all ducts connect. In Leesburg, we regularly find original flex duct from 2000s builds still holding construction drywall dust plus agricultural particulates drawn in from nearby fields. Every run is photographed before and after. Air Duct Cleaning in Leesburg is quoted with a written price before work starts.
Dryer Vent Cleaning in Leesburg
Dryer vent blockages are a fire hazard, and Leesburg’s larger homes often have long vent runs through exterior walls or roof caps that trap lint. We clear the full line with rotary brushes and verify airflow at termination. Dryer Vent Cleaning in Leesburg includes a written scope and photo documentation.
Duct Repair & Sealing in Leesburg
Aging flex duct in 2000s-era homes develops sags, tears, and disconnected joints that bleed conditioned air into attics and crawl spaces. We repair or replace damaged sections and seal leaks with mastic, not tape. Duct Repair & Sealing in Leesburg restores system efficiency and indoor pressure balance.

AfterHVAC Cleaning in Leesburg
Full HVAC cleaning in Leesburg addresses the contamination that builds where the county’s agricultural edge meets suburban housing stock. The 2000s-era Colonials in River Creek and Potomac Station have evaporator coils and blower assemblies that have run 15-20 years without cleaning, often caked with pollen, hay dust, and mold spores from humid attic conditions. We use Rotobrush and Nikro equipment for negative-pressure extraction, pulling debris out rather than pushing it deeper. HVAC Cleaning is our most called-for service in Loudoun County.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or musty odors when the AC cycles on in Leesburg’s humid July and August months.
What it costs in Leesburg
Evaporator coil cleaning typically runs $250-$450 in Leesburg, depending on access and contamination level.
How we do it
We remove the coil assembly, apply foaming cleaner, rinse with low-pressure water, and photograph the fin surface before reassembly.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating or cooling across zones, or dust puffing from registers when the system starts.
What it costs in Leesburg
Blower cleaning and balancing typically runs $200-$350 in Leesburg.
How we do it
We extract the blower wheel, clean blades and housing with compressed air and solvent, check motor amp draw, and rebalance before reinstalling.
What HVAC Cleaning Costs in Leesburg
| Item | Typical range in Leesburg |
|---|---|
| Evaporator coil cleaning | $250-$450 |
| Blower cleaning | $200-$350 |
| Full system HVAC cleaning | $400-$800 |
How do I know the HVAC cleaning was actually done?
Every duct run and component is photographed before and after, and you receive the complete photo record as a standard deliverable under Haven Standard Clause 2. Call (571) 487-7204 to schedule.
Why does my Leesburg home smell musty when the AC turns on?
Mold and bacterial growth on the evaporator coil and in condensate pans is common in Leesburg’s humid summers, especially in two-story Colonials with attic duct runs. Cleaning the coil and pan, plus sanitizing the plenum, eliminates the source.
Air Quality & Sanitizing in Leesburg
Air quality work in Leesburg targets the specific allergen load this location creates, hay dust, pollen, and agricultural particulates that standard filtration misses. The 2000s housing stock in Woodlea Manor and River Creek was built with basic 1-inch filters and no whole-home air treatment, leaving systems that recirculate contaminants through aging flex duct. We install and service Honeywell and Aprilaire equipment with documented performance data. Air Quality & Sanitizing is quoted with a written price before any equipment is specified.
Mold Treatment
Signs you need it
Visible mold around registers, persistent musty odors, or family members with worsening allergy symptoms during Leesburg’s humid summer months.
What it costs in Leesburg
Mold treatment for a full duct system typically runs $500-$900 in Leesburg, depending on extent and access.
How we do it
We apply EPA-registered antimicrobial through the full duct network under negative pressure, then HEPA-vacuum dead spores and verify with post-treatment photos.
UV Light Installation
Signs you need it
Repeated mold recurrence after cleaning, or a need for continuous suppression of bacteria and viruses in the air handler.
What it costs in Leesburg
UV light installation typically runs $400-$700 in Leesburg, including the lamp and power supply.
How we do it
We mount a UV-C lamp in the supply plenum, wire to the blower circuit for automatic operation, and show you the installation point in the photo record.
What Air Quality & Sanitizing Costs in Leesburg
| Item | Typical range in Leesburg |
|---|---|
| Mold treatment | $500-$900 |
| UV light installation | $400-$700 |
| Whole-home air purifier install | $800-$1,500 |
Do I need air quality work or just duct cleaning?
Duct cleaning removes built-up debris; sanitizing kills biological contaminants like mold and bacteria. In Leesburg’s humid climate with agricultural allergen loads, we often recommend both for homes with 15-20 year old systems.
Will UV lights actually reduce allergens in my Leesburg home?
UV-C lamps suppress mold and bacterial growth on the coil and in the plenum, which reduces the spores and byproducts that trigger symptoms. They do not filter pollen or dust; for that, we pair UV with upgraded filtration.
