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 $450-$850 for whole-system work on multi-zone homes, with air quality and sanitizing services adding $200-$600 depending on scope. The combination of oversized luxury homes, original 1980s-2000s flexible ductwork, and sustained Potomac valley humidity means McLean systems accumulate debris and microbial growth faster than inland Northern Virginia markets. Call (240) 771-1508 for a written estimate before any work begins.
Why McLean Homes Are Different
McLean sits in the Potomac River valley, where ambient relative humidity stays consistently higher than suburbs even a few miles west. That sustained moisture load pushes mold colonization on duct liner surfaces and insulation beyond what drier DC-area markets experience.
The housing stock amplifies the problem. Large luxury homes built during the 1980s-2000s lobbying boom, many 5,000-10,000+ square feet, carry complex multi-zone HVAC systems whose original flexible ductwork has now cycled 25-40 years of humidity. The teardown-and-rebuild cycle layers new construction onto 1960s-70s cores, leaving original galvanized or fiberglass duct-board plenums untouched through cosmetic renovations. Technicians regularly find 1970s fiberglass duct board intact in attic runs of homes with fully renovated kitchens and baths, the deteriorating liner shedding glass fibers into supply air. Three or more air handlers and hundreds of linear feet through unconditioned attics and crawl spaces are routine.
Our Main McLean Services
McLean homeowners contact us most often for deep system cleaning and documented duct repair. Three additional services have dedicated McLean pages:
Air Duct Cleaning in McLean
We clean every duct run in McLean homes with negative-pressure extraction, photographing the interior before and after each pass. The oversized networks in estates like those along Georgetown Pike or Chain Bridge Road require longer run times and specialized equipment to maintain proper airflow through hundreds of linear feet. Every job concludes with a Documented Photo Record delivered to the customer. Air Duct Cleaning in McLean
Dryer Vent Cleaning in McLean
Dryer vent blockages in McLean’s larger homes often involve extended horizontal runs through finished basements or multi-story chases that standard brushes cannot navigate. We use flexible rotary tools and camera verification to clear lint accumulation in runs exceeding 35 feet, common in homes with laundry rooms distant from exterior walls.

Duct Repair & Sealing in McLean
Original ductwork in McLean’s 1970s-80s stock suffers from kinked flexible liner, separated seams at plenum connections, and collapsed insulation in unconditioned zones. We repair or replace damaged sections and seal leakage points with mastic and metal-backed tape, then pressure-test to verify results. Duct Repair & Sealing in McLean

BeforeAfterHVAC Cleaning in McLean
McLean’s multi-zone systems, often 25-40 years old, distribute conditioned air through duct networks that have never been opened for maintenance. The Potomac valley humidity deposits moisture on evaporator coils and blower assemblies, creating biofilm that restricts airflow and degrades indoor air quality. HVAC Cleaning addresses the full air-handling chain, not just duct surfaces.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from registers, or musty odor when the compressor cycles on.
What it costs in McLean
Evaporator coil cleaning in McLean runs $180-$340 for accessible A-coils in attic air handlers, with price increasing if the coil requires removal for deep cleaning.
How we do it
We access the coil through the plenum, apply foaming cleaner to break biofilm, rinse with low-pressure water, and photograph the fins before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow between rooms, or dust streaking from supply registers.
What it costs in McLean
Blower assembly cleaning in McLean ranges $150-$280 for standard squirrel-cage blowers, with additional labor for multi-speed or ECM motors in newer systems.
How we do it
We remove the blower housing, clean the wheel and housing with compressed air and solvent, balance the assembly, and document runout with a photo.
What HVAC Cleaning Costs in McLean
| Item | Typical range in McLean |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower assembly cleaning | $150-$280 |
| Full HVAC cleaning (coil + blower + housing) | $450-$850 |
How long does HVAC cleaning take in a large McLean home?
Most McLean jobs run 4-6 hours for multi-zone systems with three or more air handlers, compared to 2-3 hours for standard single-system homes. Call (240) 771-1508 for a written estimate with time estimate included.
Will cleaning damage my older HVAC components?
We inspect all components before cleaning and document condition with photos; fragile fiberglass duct board or corroded coils are flagged for repair rather than forced cleaning. Haven Standard Clause 1 requires written price and scope agreement before any work begins.
Air Quality & Sanitizing in McLean
McLean’s sustained humidity and aging duct liner create conditions for mold and bacterial colonization that dry inland markets rarely match. Air quality and sanitizing targets the microbial load inside ductwork and on system components, not surface dust. Air Quality & Sanitizing
Mold Treatment
Signs you need it
Visible black or green growth on register fins, musty odor that intensifies when the system runs, or recent water intrusion in attic or crawl space duct runs.
What it costs in McLean
Mold treatment in McLean ranges $300-$650 for localized application to affected duct runs, with whole-system treatment for large homes at the upper end.
How we do it
We apply EPA-registered antimicrobial through the duct network under negative pressure, fog unlined plenums directly, and collect post-treatment swab samples for documentation.
UV Light Installation
Signs you need it
Recurring mold after cleaning, family members with allergy symptoms that worsen seasonally, or systems in damp basement or crawl space locations.
What it costs in McLean
UV-C light installation in McLean runs $400-$750 per air handler including lamp, housing, and electrical connection to the blower circuit.
How we do it
We mount the UV lamp downstream of the coil with a sight glass for inspection, wire to the blower relay for automatic operation, and show the customer the installation photo.
What Air Quality & Sanitizing Costs in McLean
| Item | Typical range in McLean |
|---|---|
| Mold treatment (localized) | $300-$650 |
| UV-C light installation per air handler | $400-$750 |
| Bacteria sanitizing (whole system) | $200-$450 |
Does mold treatment require me to leave the house?
No evacuation is needed for standard antimicrobial fogging; we ventilate the home for 30 minutes post-treatment and provide the safety data sheet on request. Call (240) 771-1508 to schedule with written scope.
How do I know the mold is actually gone?
We photograph every treated run before and after, and post-treatment swab documentation is included in your job record under the 365-Day Done Right Promise.

FAQs About Air Duct Cleaning in McLean
Most McLean HOAs do not require advance notice for interior residential service work, though gated communities like Salona Village may need entry coordination; we handle homeowner notification and carry proof of insurance for any gatehouse request.
The Potomac valley’s sustained moisture load means McLean systems typically need cleaning every 3-4 years rather than the 5-7 year interval adequate for drier inland markets, particularly homes with original fiberglass duct board.
Yes, our technicians are background-checked under Haven Standard Clause 3 and identified by name before arrival; we coordinate with homeowners for gate codes or security disarm procedures without storing sensitive access information.
