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.

AfterAir Duct Cleaning in Annandale, VA
HVAC cleaning in Annandale typically runs $380-$620 for a full system, and every job starts with a written price before work begins. Annandale’s 1950s-1970s ranch and split-level homes carry original or first-replacement ductwork now 50-65 years old, routing through damp crawl spaces above clay-heavy soil that traps moisture against metal joints. We’re CleanRun Duct Repair & Cleaning, and we dispatch crews to Annandale from our Washington, DC office. Call (240) 771-1508 for a free estimate.
Why Annandale Homes Are Different
Annandale sits at the heart of Fairfax County’s first postwar suburban wave. The core neighborhoods, including Broyhill Park, are packed with ramblers and split-levels built between roughly 1955 and 1972. Many still run on original galvanized sheet-metal ductwork or deteriorated fiberglass duct board from early replacements. These systems snake through low crawl spaces rather than finished basements, and Northern Virginia’s humid subtropical climate pushes moisture against every joint.
The mature oak and maple canopy here is denser than in newer Fairfax suburbs like Burke or Centreville. That means heavier pollen loads pushing through return-air grilles into aging ductwork. Combine that with clay-heavy soil that traps moisture under crawl-space runs, and technicians find biological contamination and joint separations that simply don’t show up in slab-foundation communities nearby.
Our Main Annandale Services
Annandale homeowners call us most often for these three services:
Air Duct Cleaning in Annandale
We clean every duct run with negative-pressure extraction, photographing the interior before and after so you can see what came out. In Annandale’s older homes, we regularly find debris build-up at the first elbow where flexible connections have sagged in damp crawl spaces. Air Duct Cleaning in Annandale includes the full Documented Photo Record as standard.
Dryer Vent Cleaning in Annandale
Dryer vents in Annandale’s ranch homes often run long horizontal paths through exterior walls, collecting lint where the run dips slightly with house settling. We clear the full line and check exterior termination hoods for the mature-tree debris that blocks them here more than in open suburbs. Dryer Vent Cleaning in Annandale is quoted upfront, same as every job.
Duct Repair & Sealing in Annandale
Joint separations are common in Annandale’s 50-plus-year-old systems, especially where flexible connectors have dried and cracked in unconditioned crawl spaces. We seal with mastic or replace failed sections, photographing every repair. Duct Repair & Sealing in Annandale stops your system from pulling unconditioned crawl-space air into living spaces.

BeforeAfterHVAC Cleaning in Annandale
Full HVAC cleaning in Annandale addresses the contamination that builds up in components downstream of those aging duct runs. The evaporator coil and blower assembly sit in humid air handlers, often in tight utility closets or crawl-space plenums, where pollen and mold spores from the mature tree canopy settle and breed. HVAC Cleaning from CleanRun includes every component, photographed before and after, with a written price locked in before we touch a panel.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from registers, or musty odors when the AC cycles on in humid summer months.
What it costs in Annandale
Evaporator coil cleaning typically runs $180-$340 in Annandale, depending on access and contamination level.
How we do it
We remove the coil assembly where accessible, apply foaming cleaner, rinse with low-pressure water, and photograph the fins before reassembly.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating or cooling across rooms, or visible dust puffing from registers at startup.
What it costs in Annandale
Blower motor and wheel cleaning typically runs $160-$290 in Annandale.
How we do it
We extract the blower assembly, clean the wheel blades and housing with compressed air and solvent, balance the wheel, and document with before-and-after photos.
What HVAC Cleaning Costs in Annandale
| Item | Typical range in Annandale |
|---|---|
| Full HVAC system cleaning | $380-$620 |
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $160-$290 |
How do I know the HVAC cleaning was actually done?
Every component is photographed before and after, and you receive the Documented Photo Record as a standard deliverable with your invoice. Call (240) 771-1508 for an exact quote - estimates are free.
Why does my Annandale home smell musty when the AC runs?
The combination of aging ductwork, crawl-space moisture, and heavy pollen loads creates ideal conditions for microbial growth on the evaporator coil and in the plenum. Cleaning removes the source, not just the symptom. Call (240) 771-1508 for an exact quote - estimates are free.
Air Quality & Sanitizing in Annandale
Air quality work in Annandale targets the biological contamination that thrives in 50-65-year-old duct systems running through damp, pollen-heavy crawl spaces. Mold and bacteria colonies establish in joint separations and low points where condensation pools, then distribute through every room. Air Quality & Sanitizing from CleanRun treats the source with documented before-and-after verification, not surface sprays that leave the problem intact.
Mold Treatment
Signs you need it
Visible black or green growth at registers, persistent musty odors, or family members with worsening allergy symptoms in humid summer months.
What it costs in Annandale
Mold treatment for ductwork and air handler typically runs $450-$780 in Annandale, based on contamination extent and access difficulty.
How we do it
We apply EPA-registered antimicrobial through the full system, fog into every duct run with a Venturi atomizer, and photograph treated surfaces for the job record.
UV Light Installation
Signs you need it
Recurring mold after cleaning, chronic allergy symptoms, or a home with continuous humidity above 60% due to crawl-space conditions.
What it costs in Annandale
UV-C light installation in the air handler or plenum typically runs $320-$550 in Annandale, including the lamp and electrical connection.
How we do it
We mount a Honeywell or Aprilaire UV lamp upstream of the coil, wire to the blower circuit for automatic operation, and show you the installation photo in your record.
What Air Quality & Sanitizing Costs in Annandale
| Item | Typical range in Annandale |
|---|---|
| Mold treatment (full system) | $450-$780 |
| UV light installation | $320-$550 |
| Bacteria sanitizing | $280-$480 |
Is UV light worth it in Annandale’s humid climate?
Yes - the persistent moisture in crawl-space duct systems here makes mold recurrence likely without continuous suppression. UV-C at the coil surface prevents regrowth between cleanings. Call (240) 771-1508 for an exact quote - estimates are free.
How do I know mold treatment worked?
We photograph treated surfaces before and after, deliver the Documented Photo Record with your invoice, and back the work with our 365-Day Done Right Promise. Call (240) 771-1508 for an exact quote - estimates are free.
