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 McLean, VA
HVAC cleaning in McLean typically runs $400-$800 for a full system, with air quality and sanitizing services adding $150-$450 depending on scope. Call (240) 363-3380 for a written estimate before any work begins.
McLean’s housing market follows a tear-down-and-rebuild rhythm that creates two distinct ductwork profiles: original 1960s-80s systems in neighborhoods like Broyhill McLean Estates, and brand-new multi-zone installations in 6,000-10,000 sq ft replacements. Both present cleaning challenges you won’t find in Vienna or Falls Church. The vintage stock uses fibrous duct board that degrades and sheds fibers; new construction traps drywall dust and insulation debris that bypasses standard filters. Our crews have documented both conditions since 2013, with every job photographed before and after under the Haven Standard.
Why McLean Homes Are Different
McLean sits in the humid Piedmont corridor just above the Potomac River valley, where summer dew points regularly exceed 70°F. That moisture condenses inside flex duct running through the deep finished basements that are standard here, creating conditions for mold growth that Northern Virginia’s heavy spring pollen load only worsens. The wooded, large-lot properties common throughout McLean pull extraordinary particulate volumes through return-air systems.
The housing stock amplifies these climate effects. Established neighborhoods like Chesterbrook contain 1960s-70s colonials and split-levels with complex duct systems, many still on original fibrous duct board that delaminates over decades. Meanwhile, estate lots increasingly host newly built custom homes with long duct runs through multiple floors. Both scenarios involve unusually large cleaning scopes compared to typical Fairfax County suburbs. In unrenovated 1960s homes that escaped the tear-down wave, we regularly find degraded fiberglass duct board shedding glass fibers directly into the airstream, a failure mode neighboring markets like Reston or Ashburn rarely present at this frequency.
Our Main McLean Services
McLean homeowners call us most often for these three services, each with its own dedicated page:
Air Duct Cleaning in McLean
We clean the full duct network, registers to plenum, using negative-pressure extraction with Rotobrush and Nikro equipment. In McLean’s large homes, this often means 20+ duct runs across multiple zones, with particular attention to return lines pulling pollen from wooded lots. Every run is photographed before and after. Air Duct Cleaning in McLean covers full pricing and scope details.
Dryer Vent Cleaning in McLean
Dryer vent blockages are common in McLean’s multi-story homes with long horizontal runs through finished basements. We clear the full line from appliance to termination, test airflow, and document the before-and-after differential. Dryer Vent Cleaning in McLean has full details.
Duct Repair & Sealing in McLean
We repair disconnected runs, seal leaks with mastic, and replace degraded flex duct. McLean’s original 1960s-80s systems often need partial rebuilds where duct board has collapsed. Duct Repair & Sealing in McLean covers repair pricing and scope.

BeforeAfterHVAC Cleaning in McLean
McLean’s bimodal housing stock, split between aging original systems and new multi-zone installations, means HVAC cleaning here addresses two distinct problems: decades of accumulated debris in legacy equipment, and construction residue in systems that have never run clean. The humid summers and heavy pollen loads compound both. Our HVAC Cleaning service covers the full mechanical system, not just ductwork, with documented photo records of every component.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, weak airflow from registers, or cooling that can’t keep up during McLean’s humid July afternoons.
What it costs in McLean
Evaporator coil cleaning typically runs $250-$450 in McLean, depending on accessibility and contamination level.
How we do it
We remove the coil assembly where possible, apply foaming cleaner, rinse with low-pressure water, and photograph the fin condition before reassembly.
Blower Cleaning
Signs you need it
Dust puffing from registers at startup, uneven airflow between rooms, or a blower motor laboring louder than when new.
What it costs in McLean
Blower cleaning and motor inspection typically costs $200-$350 in McLean homes.
How we do it
We remove the blower assembly, clean the squirrel cage and housing, lubricate bearings if serviceable, and balance the wheel before reinstalling.
What HVAC Cleaning Costs in McLean
| Item | Typical range in McLean |
|---|---|
| Evaporator coil cleaning | $250-$450 |
| Blower cleaning | $200-$350 |
| Full HVAC system cleaning (coil, blower, air handler) | $400-$800 |
How do I know my HVAC system needs cleaning, not just the ducts?
If rooms cool unevenly, the blower runs louder than it used to, or you see ice on the coil, the mechanical components need attention beyond duct cleaning. Call (240) 363-3380 and we’ll scope the full system in writing.
Can HVAC cleaning fix humidity problems in my McLean home?
A dirty evaporator coil can’t dehumidify efficiently; cleaning restores proper condensation drainage, though oversized systems common in new McLean construction may need additional assessment. We document coil condition and airflow before recommending further steps.
Air Quality & Sanitizing in McLean
McLean’s combination of humid summers, heavy tree pollen, and deep basements with long duct runs creates conditions where biological contamination persists after mechanical cleaning alone. New construction adds drywall dust and insulation particulate that standard filtration misses. Our Air Quality & Sanitizing service addresses what extraction leaves behind, with application records photographed and delivered as part of the job documentation.
Mold Treatment
Signs you need it
Musty odor from registers, visible growth at duct joints, or condensation stains on ceiling panels above basement runs.
What it costs in McLean
Mold treatment for localized duct contamination typically runs $300-$600 in McLean, with whole-system applications ranging higher based on square footage and access.
How we do it
We apply EPA-registered antimicrobial through the full duct network using Abatement Technologies fogging equipment, with dwell time documented before airflow restoration.
UV Light Installation
Signs you need it
Recurring mold after cleaning, high humidity in the air handler cabinet, or family members with persistent respiratory sensitivity.
What it costs in McLean
UV light installation in the air handler or plenum typically costs $400-$800 in McLean, including the lamp and electrical connection.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp upstream of the coil, wire to the blower circuit for automatic operation, and photograph placement for the job record.
What Air Quality & Sanitizing Costs in McLean
| Item | Typical range in McLean |
|---|---|
| Mold treatment (localized duct application) | $300-$600 |
| UV light installation | $400-$800 |
| Whole-system sanitizing with antimicrobial | $350-$700 |
Is mold treatment safe for children and pets?
We use EPA-registered products applied to manufacturer dwell specifications, with no re-entry restrictions beyond standard ventilation time; the application record notes exact product and concentration used. Call (240) 363-3380 for product sheets before scheduling.
How long does UV light installation take?
Most UV installations in McLean homes finish in 2-3 hours, including mounting, electrical connection, and testing; we photograph lamp placement and document the warranty period in the job record.
