AfterAir Duct Cleaning in Annandale, VA
Dryer vent cleaning in Annandale runs $149-$289 for a standard single-family home, and we see a lot of vents here that haven’t been touched since the Reagan administration. Annandale’s 1950s-1970s split-levels and cape cods route dryer ducts through crawl spaces and tight utility closets, which means lint builds up fast and the runs are hard to reach. Call (806) 606-6902 if your dryer has been taking two cycles to dry a load. We’ll give you a written price before we touch anything.
Why Annandale Homes Are Different
Annandale’s housing stock is dense with split-levels and ranch homes built during Fairfax County’s postwar suburban boom. Most still run their original or once-replaced sheet-metal and duct-board systems, and unlike neighboring communities that have seen heavier renovation, Annandale’s housing has aged in place. That matters for duct work in two ways. First, fiberglass duct board lining from that era has degraded over 50-plus years, shedding particulates into the airstream inside homes across Wakefield Chapel, Broyhill Crest, and Camelot. Second, many of these homes route ductwork through unconditioned crawl spaces or cramped attic chases, which means condensation in summer and chronic moisture exposure year-round.
The climate compounds this. Northern Virginia’s humid subtropical pattern pushes dew points above 70°F through most of the summer. Inside a cooled duct system, that humidity condenses on the metal surfaces. In an older, less-insulated Annandale duct run, that condensation soaks into the fiberglass liner and creates conditions where mold colonization takes hold. Add the dense oak and mixed hardwood canopy dropping a heavy spring pollen load, and the return-air ducts in these homes accumulate more biological material in one season than a newer-construction home sees in five years.
Our Main Annandale Services
Most Annandale homeowners call us about two jobs: cleaning the ducts that move heated and cooled air, and cleaning the HVAC system itself. Here’s what each involves in this area.
Air Duct Cleaning in Annandale
Air duct cleaning in Annandale means removing the accumulated dust, pollen, pet dander, and degraded fiberglass liner particles from the full duct run, from the return registers to the supply vents. In these older split-levels, we frequently find disconnected joints at the return plenum that have been pulling crawl-space air into the living area for years. The job includes a camera inspection before and after, negative-pressure extraction with Rotobrush or Nikro equipment, and a documented photo record of every run. See the full service details on our Air Duct Cleaning in Annandale page.
HVAC Cleaning in Annandale
HVAC cleaning in Annandale covers the air handler, evaporator coil, blower motor, and condensate pan, all of which collect the same dust and biological load that the ducts do. In homes off Little River Turnpike and Columbia Pike, we often find coils coated with a layer of lint and pollen that cuts airflow by a measurable margin. The job includes coil cleaning, blower cleaning, pan treatment, and a written report on what was found. Details and current pricing are on the HVAC Cleaning in Annandale page.

BeforeAfterDryer Vent Cleaning in Annandale
Dryer vent cleaning in Annandale means clearing the full run from the dryer to the exterior termination, and in these 1950s-1970s homes the run is often long, angled, and lined with lint that has baked into a dense mat. Most of the dryer vents we service here are original sheet-metal runs that exit through the roof or a side wall, and many run through unconditioned spaces that make standard cleaning more demanding. If your clothes take two cycles to dry, the vent is the first place we look. Every job is priced in writing before work starts, and the inside of the vent is photographed before and after. Call (806) 606-6902 for a price. You can read our full process on the Dryer Vent Cleaning page.
Dryer Vent Inspection
Signs you need it
Your dryer takes longer than 45 minutes to dry a standard load, or the exterior vent flap doesn’t open when the dryer runs.
What it costs in Annandale
A camera inspection of the full dryer vent run typically costs $79-$149, refunded if you proceed with cleaning.
How we do it
We run a camera from the dryer connection to the exterior termination, check every joint and transition, and show you what the camera sees before any work is quoted.
Lint Removal
Signs you need it
The dryer feels hot to the touch, the laundry room smells musty, or visible lint is accumulating around the exterior vent opening.
What it costs in Annandale
Lint removal from a typical Annandale dryer vent runs $149-$289, depending on run length and the density of the buildup.
How we do it
We use a powered rotary brush matched to the vent diameter, work the full run from both ends, and finish with negative-pressure extraction to pull the loosened lint out rather than pushing it deeper.
Vent Rerouting
Signs you need it
Your current vent run exceeds the manufacturer’s maximum length, makes more than two 90-degree turns, or terminates in a place that vents into the crawl space.
What it costs in Annandale
Rerouting a dryer vent in Annandale runs $325-$650, with the final price depending on the new path and the number of wall penetrations.
How we do it
We design the shortest straight-line run that meets code, replace the old run with rigid metal duct, and seal every joint with mastic so the system holds negative pressure.
Bird Guard Installation
Signs you need it
Birds or nesting material are visible at the exterior vent termination, or you hear activity inside the vent pipe.
What it costs in Annandale
Bird guard installation in Annandale runs $75-$150, including the guard, the mounting hardware, and a check of the termination point.
How we do it
We remove any nesting material with extraction equipment, then mount a screened guard over the termination that keeps birds out while allowing full airflow.
What Dryer Vent Cleaning Costs in Annandale
| Item | Typical range in Annandale |
|---|---|
| Dryer Vent Inspection | $79-$149 |
| Lint Removal | $149-$289 |
| Vent Rerouting | $325-$650 |
| Bird Guard Installation | $75-$150 |
Long runs with multiple bends push the lint removal price toward the upper end. Every job is quoted as one written price before work begins.
How often should a dryer vent be cleaned in Annandale?
Every 12 months for a household that runs the dryer three or more times a week. Annandale’s older duct runs trap lint faster, so annual cleaning is the safe interval. Call (806) 606-6902 to schedule.
Can you clean a dryer vent that is clogged with years of lint?
Yes. We routinely pull dense, compacted lint mats from vents in Annandale homes that have not been cleaned in a decade or more. The powered brush breaks up even hardened buildup. Call (806) 606-6902 for an exact price.
Duct Repair & Sealing in Annandale
Duct repair and sealing in Annandale means fixing disconnected joints, crushed flex runs, and holes in sheet-metal ducts that pull crawl-space air into your living space. These older homes have return-air plenums that frequently leak at the seams, and once a joint separates, the system pulls from the crawl space instead of the conditioned rooms. We find this in split-levels all over Annandale, and the fix is a written-price job that stops the leak and stops the air quality problem at the same time. The full service breakdown is on our Duct Repair & Sealing page.
Duct Sealing
Signs you need it
Rooms at the far end of the house never reach the thermostat temperature, or your energy bills are high despite a newer HVAC system.
What it costs in Annandale
Sealing a typical Annandale duct system runs $450-$1,200, depending on the number of accessible joints and the sealing method used.
How we do it
We apply mastic sealant to every accessible joint and seam, then test the system with a duct leakage measurement to confirm the improvement in numbers.
Flex Duct Repair
Signs you need it
You see crushed or kinked flex duct in the attic or crawl space, or one branch of the system delivers noticeably less airflow than the others.
What it costs in Annandale
Replacing a damaged flex duct section in Annandale runs $175-$400 per run, depending on the diameter and length of the replacement section.
How we do it
We cut out the damaged section, install new flex duct sized to the original design, and support it properly so it cannot kink or sag again.
Duct Insulation
Signs you need it
Ducts in the attic or crawl space sweat in the summer, or you feel condensation on exposed metal surfaces during humid weeks.
What it costs in Annandale
Insulating exposed ductwork in an Annandale attic or crawl space runs $350-$900, depending on the total length of the runs.
How we do it
We wrap the exterior of the duct with fiberglass insulation of the specified R-value, then secure and seal it so the insulation never touches the metal directly.
What Duct Repair & Sealing Costs in Annandale
| Item | Typical range in Annandale |
|---|---|
| Duct Sealing | $450-$1,200 |
| Flex Duct Repair | $175-$400 per run |
| Duct Insulation | $350-$900 |
Access difficulty is the main variable in Annandale. Tight attic chases and low crawl spaces make some jobs slower, and that shows up in the written price, not as a surprise at the end.
How do I know if my Annandale ducts are leaking?
A duct leakage test gives you a number. We pressurize the system and measure how much air escapes. Most older Annandale homes show leakage of 20% or more. Call (806) 606-6902 to get yours tested.
Can you repair just one leaking duct joint?
Yes. If the camera inspection shows one disconnected joint, we can seal that joint on its own. The written price covers the specific scope, nothing more. Call (806) 606-6902 for a quote.
Air Quality & Sanitizing in Annandale
Air quality and sanitizing in Annandale addresses the mold, bacteria, and microbial growth that takes hold inside these older, moisture-prone duct systems. The humid Potomac watershed summers, with dew points above 70°F, condense water inside cooled ducts, and the degraded fiberglass liner in 50-year-old systems gives mold exactly the surface it needs. We treat the source with professional-grade antimicrobials and, when the homeowner wants ongoing protection, install UV light systems inside the air handler. Full details are on our Air Quality & Sanitizing page.
Mold Treatment
Signs you need it
You see visible mold growth on duct surfaces during a camera inspection, or a musty odor persists in the house no matter how often you clean.
What it costs in Annandale
Mold treatment of a typical Annandale duct system runs $500-$1,500, depending on the extent of the colonization and the number of duct runs affected.
How we do it
We apply an EPA-registered antimicrobial to the interior surfaces of the ductwork with a fogging system, then follow with an air scrubber to remove airborne spores before the system is restarted.
Bacteria Sanitizing
Signs you need it
The HVAC system has been off for a long period, or there has been water intrusion near the air handler or ductwork, leaving a persistent stale smell.
What it costs in Annandale
Bacteria sanitizing in Annandale runs $350-$800, depending on the size of the system and the number of coils and surfaces treated.
How we do it
We clean the coil, pan, and blower surfaces first, then apply a hospital-grade sanitizer registered for HVAC use to every interior surface the air passes over.
UV Light Installation
Signs you need it
Mold returns repeatedly after cleaning, or a household member has respiratory issues that worsen when the HVAC runs.
What it costs in Annandale
UV light installation in Annandale runs $450-$1,100, including the unit, mounting, and electrical connection inside the air handler.
How we do it
We mount a UV-C lamp in the air handler aimed at the coil, wire it to run continuously, and show you the lamp operation before we leave.
Odor Removal
Signs you need it
A smell from the vents persists after the ducts have been cleaned, or the odor gets stronger when the system switches between heating and cooling.
What it costs in Annandale
Odor removal in Annandale runs $300-$700, depending on whether the source is in the ducts, the coil, or the air handler cabinet.
How we do it
We locate the odor source with the camera, clean or replace the affected materials as needed, and run an ozone or activated-oxygen treatment through the system to neutralize remaining odor compounds.
What Air Quality & Sanitizing Costs in Annandale
| Item | Typical range in Annandale |
|---|---|
| Mold Treatment | $500-$1,500 |
| Bacteria Sanitizing | $350-$800 |
| UV Light Installation | $450-$1,100 |
| Odor Removal | $300-$700 |
Annandale’s aging fiberglass duct liner adds cost when it has to be removed and replaced before sanitizing can be effective. We show you the condition on the camera before quoting that work.
Will sanitizing my ducts get rid of the musty smell in my Annandale house?
If the smell originates in the duct system, yes. We treat the surfaces where the odor compounds live. If the source is in the crawl space, sealing the ducts is the fix. Call (806) 606-6902 for an assessment.
Is mold in ductwork actually dangerous?
Mold spores in the airstream are an indoor air quality problem, and for people with asthma or allergies, they are a health trigger. We recommend treating visible mold in ducts rather than leaving it. Call (806) 606-6902 to schedule an inspection.
