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 our crews in Fairfax use Rotobrush and Abatement Technologies equipment to clean every duct run with negative-pressure extraction, photographing each before and after. Dispatch and scheduling are coordinated from our Washington, DC office; crews serve Fairfax neighborhoods directly. Call (240) 363-3380 for a written estimate before any work starts.
Why Fairfax Homes Are Different
Fairfax sits at the epicenter of Northern Virginia’s massive 1970s-1990s suburban buildout, leaving the city with one of the highest concentrations of aging flex-duct and fiberglass duct-board systems in the mid-Atlantic - materials now 30-50 years old, well past manufacturer lifespan, and largely invisible to homeowners. Combined with the DC metro’s notoriously heavy spring oak and maple pollen season and suffocating summer humidity, Fairfax ducts accumulate allergen and mold loads faster than nearly any comparable suburb.
Neighborhoods like Mantua, Greenbriar, and the Burke corridor are filled with colonials, split-levels, and raised ranches built during rapid post-Vietnam expansion. Many run ductwork through unconditioned attics where summer temperatures exceed 130°F, cracking flex-duct liners and releasing degraded fiberglass particles into living spaces. Technicians here regularly find sections that have partially collapsed or separated at joints, a failure mode far less common in newer Loudoun County builds.
Our Main Fairfax Services
Most Fairfax homeowners who call us start with one of these three services:
Air Duct Cleaning in Fairfax
We clean every duct run with negative-pressure extraction, photographing the inside of each before and after. In Fairfax’s 1980s colonials, we often find original flex-duct that has sagged, torn, or accumulated years of oak pollen and humidity-driven debris. Our crews use Rotobrush equipment to dislodge buildup, then extract it with HEPA-filtered vacuums. Every job concludes with a Documented Photo Record delivered to the customer. Air Duct Cleaning in Fairfax covers whole-system cleaning for homes throughout Mantua, Greenbriar, and surrounding neighborhoods.
Dryer Vent Cleaning in Fairfax
Fairfax’s mature tree canopy means more lint accumulation combined with exterior debris. We clean the full vent run from dryer to termination, using rotary brushes and high-velocity air to remove blockages. Our technicians check for proper airflow and photograph the vent interior before and after. Dryer Vent Cleaning in Fairfax addresses the fire risk that builds in longer vent runs common in split-level and raised-ranch layouts.
Duct Repair & Sealing in Fairfax
Original ductwork in Fairfax’s post-Vietnam era homes has exceeded its design life. We repair separated joints, replace collapsed flex-duct sections, and seal leaks with mastic or metal-backed tape. Every repair is photographed and documented, with a written price agreed before any work begins. Duct Repair & Sealing in Fairfax restores airflow and efficiency in systems that have degraded in hot attics and damp basements.

BeforeAfterHVAC Cleaning in Fairfax
Fairfax’s 1965-1995 housing stock and DC metro humidity create unique HVAC contamination patterns: evaporator coils in unconditioned basements grow mold during summer months, while blower assemblies accumulate pollen and degraded fiberglass from stressed ductwork. HVAC Cleaning from CleanRun addresses these components directly, with written pricing and photo documentation for every step.
Evaporator Coil Cleaning
Signs you need it
Musty odors when the AC runs, reduced airflow from registers, or ice formation on the coil cabinet in summer.
What it costs in Fairfax
Evaporator coil cleaning in Fairfax typically runs $280-$420.
How we do it
We access the coil cabinet, apply foaming cleaner to break down mold and biofilm, rinse with low-pressure water, and photograph the coil surface before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating or cooling, or visible dust puffing from registers at startup.
What it costs in Fairfax
Blower assembly cleaning in Fairfax typically runs $240-$380.
How we do it
We remove the blower wheel and housing, clean each blade with compressed air and solvent, balance the assembly, and document with before-and-after photos.
What HVAC Cleaning Costs in Fairfax
| Item | Typical range in Fairfax |
|---|---|
| Evaporator coil cleaning | $280-$420 |
| Blower assembly cleaning | $240-$380 |
| Full HVAC system cleaning (coil + blower + housing) | $520-$720 |
How do I know my HVAC needs cleaning, not just my ducts?
If you smell must when the AC cycles on, or see ice on the coil, the contamination is in the HVAC components, not just the duct runs. Call (240) 363-3380 and we’ll inspect both systems and put a written price to each option.
Can HVAC cleaning fix the humidity smell in my Fairfax basement?
Yes, if the odor comes from mold on the evaporator coil or standing water in the condensate pan; we clean both and photograph the results. If the smell persists after cleaning, the issue may be groundwater intrusion, which we will note in writing.
Air Quality & Sanitizing in Fairfax
Fairfax’s heavy spring oak pollen and summer humidity in 80-90% range create conditions where mold colonizes duct interiors and bacteria proliferate on wet coils. Air Quality & Sanitizing targets these biological contaminants with EPA-registered treatments, not surface wipes, with every application photographed and documented.
Mold Treatment
Signs you need it
Visible black or green growth on registers or duct openings, or a persistent earthy smell when the system runs.
What it costs in Fairfax
Mold treatment for duct systems in Fairfax typically runs $380-$650.
How we do it
We apply an EPA-registered antimicrobial fog throughout the duct network, let it dwell per manufacturer specification, then extract residue and photograph treated surfaces.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, or a household member with documented mold sensitivity.
What it costs in Fairfax
UV-C light installation in Fairfax typically runs $450-$780 per unit.
How we do it
We mount a Honeywell or Aprilaire UV lamp in the supply plenum, wire it to the blower circuit, and show the customer the installation photo and lamp status indicator.
What Air Quality & Sanitizing Costs in Fairfax
| Item | Typical range in Fairfax |
|---|---|
| Mold treatment (whole system) | $380-$650 |
| UV-C light installation | $450-$780 |
| Combined mold treatment + UV installation | $750-$1,200 |
Does mold treatment kill all mold in my ducts?
Our treatment kills active mold growth on accessible surfaces; if the underlying moisture problem persists, such as a leaking duct in a humid attic, mold will return. We photograph moisture sources and note them in the written report.
How long does UV light take to work?
UV-C lamps begin reducing airborne mold and bacteria immediately, but surface biofilm reduction takes 2-4 weeks of continuous operation; we check lamp output at installation and document baseline conditions.
Brands We Service in Fairfax
We stock parts and service equipment from Honeywell, Aprilaire, Abatement Technologies, and Guardsman, with most common filters, UV lamps, and sanitizer cartridges available without ordering delay. See our brands for the full roster.

FAQs About Air Duct Cleaning in Fairfax
Most Fairfax HOAs do not require notice for interior residential service work, but some communities in Mantua and Greenbriar restrict parking for commercial vehicles; we confirm any access requirements when you schedule and carry proof of insurance if your HOA requests it.
We typically schedule Fairfax appointments within 3-5 business days; peak pollen season in April and May may extend this slightly. All calls are answered by a live person who can check real-time crew availability.
Only if your ductwork runs through the attic, which is common in 1980s Fairfax colonials; we bring portable ladders and protective sheeting, and we photograph any attic duct conditions we find as part of the standard documentation.

- Petra K."The before and after photographs of each run are the reason I used them. You cannot argue with what came out of the return."
