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 a whole-system service, with most jobs scheduled within a week and completed in one day. McLean’s mix of 1960s-era ranch homes and new 8,000 sq ft custom builds means no two duct systems are alike, and pricing depends on zone count, duct material, and whether the home is post-construction or has decades of accumulated debris. We coordinate dispatch from our Washington, DC office and serve McLean with crews that carry Rotobrush and Nikro equipment. Call (571) 520-6317 for a written estimate.
Why McLean Homes Are Different
McLean’s housing stock splits into two eras that create completely different ductwork profiles. The original 1960s-1980s colonials and split-levels in neighborhoods like Chain Bridge Forest often still carry early-generation flex duct or galvanized trunk lines that have never been cleaned. These systems accumulate pollen, dust, and microbial growth through decades of the DC metro’s humid summers, where relative humidity stays above 70% from June through August.
Then there is the teardown cycle. In Langley Oaks and surrounding core neighborhoods, 1960s ranches are routinely demolished and replaced with 6,000-10,000 sq ft custom estates. These new homes feature three or more HVAC zones and hundreds of linear feet of ductwork, but they also arrive filled with drywall dust, insulation fibers, and sawdust that must be cleared before occupancy. A technician can service a brand-new custom home on Tuesday and clean 50-year-old galvanized lines two doors down on Wednesday. That range makes uniform pricing impossible and site assessment non-negotiable.
McLean’s dense tree canopy adds another factor: heavy spring pollen loads that clog return-air grilles and drive repeat seasonal demand. Older flex-duct systems with porous liner surfaces are particularly vulnerable to microbial growth in these conditions.
Our Main McLean Services
McLean homeowners call us most often for these three services, each with its own dedicated page and pricing structure.
Air Duct Cleaning in McLean
Whole-system duct cleaning for McLean homes, from single-zone ranches to multi-zone new construction. We photograph every duct run before and after, and we clear post-construction debris from new builds as well as decades of accumulation from original systems. Every job starts with a written price before any panel comes off. Air Duct Cleaning in McLean covers full scope and pricing.
Dryer Vent Cleaning in McLean
Dryer vent cleaning addresses lint buildup that restricts airflow and creates fire risk, particularly in McLean’s larger homes where vent runs can exceed 35 feet. We clean the full run from appliance to termination, inspect for proper airflow, and document the before-and-after condition. Dryer Vent Cleaning in McLean has full details.
Duct Repair & Sealing in McLean
Duct repair and sealing fixes disconnected runs, corroded galvanized sections, and leaks at plenum joints that waste conditioned air in McLean’s older stock. For new construction, we seal accessible joints to meet modern efficiency standards. Every repair scope is priced in writing before work begins. Duct Repair & Sealing in McLean explains our approach.

BeforeAfterHVAC Cleaning in McLean
McLean’s humid summers and mixed housing stock make HVAC cleaning a priority for both system performance and indoor air quality. In older homes with galvanized trunk lines, we regularly find blower wheels caked with decades of debris that reduces airflow by 30% or more. In new construction, evaporator coils arrive coated with construction dust that restricts heat transfer before the first owner moves in. Our HVAC Cleaning service addresses each component with documented photo records and written upfront pricing under Haven Standard Clause 1.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or cooling that cannot keep up with McLean’s July humidity peaks.
What it costs in McLean
Evaporator coil cleaning typically runs $280-$450 in McLean, with accessibility through the plenum or a dedicated access panel affecting the final price.
How we do it
We access the coil through the plenum (the main air distribution box), apply foaming cleaner approved for aluminum fins, rinse with low-pressure water, and photograph the coil before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating or cooling across zones, or visible dust puffing from registers when the system cycles on.
What it costs in McLean
Blower cleaning in McLean ranges from $220-$380, with squirrel-cage assemblies in older systems taking longer to remove and clean properly.
How we do it
We remove the blower assembly, clean the squirrel-cage wheel and housing with compressed air and solvent, balance the assembly, and reinstall with a documented photo record.
What HVAC Cleaning Costs in McLean
| Item | Typical range in McLean |
|---|---|
| Evaporator coil cleaning | $280-$450 |
| Blower cleaning | $220-$380 |
| Full HVAC system cleaning (coil, blower, air handler) | $450-$850 |
How do I know my HVAC needs cleaning versus just my ducts?
If your registers blow weak or warm air despite clean ducts, or if the system runs continuously without reaching set temperature, the blower or coil is likely restricted. We inspect both during our site assessment and show you the photo evidence before quoting.
Can HVAC cleaning fix humidity problems in my McLean home?
A dirty evaporator coil cannot dehumidify properly because dust insulates the fins and reduces condensation runoff. Cleaning restores designed moisture removal, though oversized systems common in McLean’s new construction may need additional assessment.
Air Quality & Sanitizing in McLean
McLean’s mature tree canopy and humid summers create conditions where microbial growth thrives inside ductwork, particularly in older flex-duct systems with porous liners. New construction brings its own air quality concerns: off-gassing from building materials and trapped construction dust that circulates for months. Our Air Quality & Sanitizing service treats these problems with documented application records and the 365-Day Done Right Promise.
Mold Treatment
Signs you need it
Musty odor when the system runs, visible discoloration on register boots, or persistent allergy symptoms that worsen with HVAC use in McLean’s humid months.
What it costs in McLean
Mold treatment for accessible duct runs typically ranges $350-$650 in McLean, with extent of growth and duct material determining scope.
How we do it
We apply EPA-registered antimicrobial through the duct system using negative-pressure extraction equipment, then verify treatment with post-application photos of treated surfaces.
UV Light Installation
Signs you need it
Recurrent microbial growth after cleaning, or a home with chronic moisture issues common in McLean’s older basements and crawl spaces.
What it costs in McLean
UV light installation runs $480-$780 in McLean, including the lamp, mounting hardware, and electrical connection to the air handler.
How we do it
We mount a Honeywell or Guardsman UV-C lamp downstream of the evaporator coil, wire to the air handler’s 24V circuit, and provide replacement schedule documentation.
What Air Quality & Sanitizing Costs in McLean
| Item | Typical range in McLean |
|---|---|
| Mold treatment (duct system) | $350-$650 |
| UV light installation | $480-$780 |
| Whole-system sanitizing (mold + bacteria treatment) | $450-$750 |
Is mold treatment safe for my family during application?
We use EPA-registered products with re-entry times typically under four hours, and we ventilate the home thoroughly before occupants return. The written scope specifies product and dwell time before we begin.
Do UV lights actually prevent mold in McLean’s humidity?
UV-C lamps inhibit microbial growth on the coil and nearby surfaces but do not sterilize moving air; they work best as maintenance after proper cleaning, not as a standalone solution.
