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 Manassas, VA
HVAC cleaning in Manassas typically runs $380-$680 for a full system, and every job starts with a written price before we touch a single panel. Manassas homes built during the 1988-2005 suburban boom carry flexible duct systems now hitting the age where sagging, kinked runs and inner-liner debris shedding become routine problems. The combination of hot, humid Piedmont summers and some of the highest pollen loads in the mid-Atlantic means return-air ductwork here accumulates particulate faster than systems in drier climates. Call (571) 520-6317 for a written estimate.
Why Manassas Homes Are Different
Manassas sits in the Virginia Piedmont, where July and August bring sustained humidity that drives condensation inside supply ducts running through 130-140°F attics. That moisture, combined with oak, cedar, and grass pollen counts that overwhelm standard 1-inch filters, creates conditions we don’t see in drier parts of Northern Virginia.
The housing stock tells the rest of the story. Signal Hill, Yorkshire, and Sudley subdivisions were framed fast with flexible duct stapled through tight ceiling cavities. Technicians regularly find kinked runs that trap debris and restrict airflow enough that homeowners have replaced perfectly good HVAC units before discovering the ducts were the problem. Older neighborhoods near Historic Downtown Manassas may still contain 1950s-1970s sheet-metal systems with decades of accumulated particulate and possible asbestos-containing insulation.
Our Main Manassas Services
Three services account for most calls we dispatch to Manassas. Each has its own page with full pricing and scope details.
Air Duct Cleaning in Manassas
We clean every duct run with negative-pressure extraction, photograph the inside before and after, and deliver the photo record as part of the standard job file. In Manassas, flex-duct homes from the 1990s and 2000s often show liner degradation that requires gentler agitation than older sheet-metal systems. Air Duct Cleaning in Manassas
Dryer Vent Cleaning in Manassas
Dryer vents in Manassas townhomes with stacked laundry closets often run 25-35 feet with multiple elbows, creating lint traps that reduce drying efficiency and present fire risk. We rotary-brush the full length and verify airflow at termination. Dryer Vent Cleaning in Manassas
Duct Repair & Sealing in Manassas
Sagging flex duct, disconnected plenum joints, and deteriorated mastic are common in Manassas homes now 20-35 years old. We repair or replace damaged sections and seal with mastic or metal-backed tape, then pressure-test the system. Duct Repair & Sealing in Manassas

BeforeAfterHVAC Cleaning in Manassas
Full HVAC Cleaning in Manassas addresses the components competitors skip: the evaporator coil caked with pollen and dust that bypassed the filter, the blower wheel throwing off balance from debris buildup, and the condenser fins choked with cottonwood and grass clippings. In this market, we find coils so fouled that airflow drops 30% before the homeowner notices anything beyond gradually rising electric bills. The 1988-2005 housing stock’s original equipment is now at the age where neglected cleaning leads to compressor strain and premature failure.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or cooling that can’t keep up on humid August afternoons in Manassas.
What it costs in Manassas
Evaporator coil cleaning typically runs $180-$320 as a standalone service, or bundled into full HVAC cleaning at reduced scope cost.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water capture, and photograph the fin condition before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow room-to-room, or a blower wheel visible through the access panel with debris coating the blades.
What it costs in Manassas
Blower cleaning and balancing typically runs $150-$280 depending on access configuration and contamination level.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the assembly, and document runout with a photo.
What HVAC Cleaning Costs in Manassas
| Item | Typical range in Manassas |
|---|---|
| Full HVAC cleaning (coil, blower, condenser) | $380-$680 |
| Evaporator coil cleaning only | $180-$320 |
| Blower cleaning only | $150-$280 |
How often should HVAC cleaning be done in Manassas?
Every 3-5 years for homes with standard 1-inch filters; every 2-3 years if you have pets, allergies, or live near high-pollen zones like the Yorkshire or Signal Hill areas. Call (571) 520-6317 and we’ll assess your system condition.
Can HVAC cleaning fix weak airflow?
It often can, when the restriction is a fouled coil or blower wheel rather than kinked ductwork. We photograph the components first so you can see the difference between a cleaning issue and a duct repair issue before committing to either.
Air Quality & Sanitizing in Manassas
Air Quality & Sanitizing in Manassas targets the mold colonization and bacterial loading that humid summers and aging flex-duct liners produce together. Condensation inside supply ducts from July through September creates sustained moisture on organic debris, and the dark interior of a kinked duct run in a Yorkshire or Sudley ceiling cavity is an ideal mold habitat. We treat the source, not the symptom: the duct interior itself, not just a fogged room.
Mold Treatment
Signs you need it
Musty odor when the system starts, visible spotting on register faces, or recent water intrusion in the attic or crawl space.
What it costs in Manassas
Mold treatment for a full duct system typically runs $450-$850 depending on contamination extent and accessibility.
How we do it
We apply EPA-registered antimicrobial through the duct runs under negative pressure, treat the plenum and coil pan, and deliver before-and-after photos of treated surfaces.
UV Light Installation
Signs you need it
Recurring mold despite prior cleaning, chronic allergy symptoms that spike when the system runs, or a coil that fouls again within one season.
What it costs in Manassas
UV-C lamp installation at the coil or plenum typically runs $280-$520 including lamp and electrical connection.
How we do it
We mount a Honeywell or Guardsman UV-C fixture at the coil face or supply plenum, wire to the blower circuit, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Manassas
| Item | Typical range in Manassas |
|---|---|
| Full-system mold treatment | $450-$850 |
| Bacteria sanitizing (whole system) | $320-$580 |
| UV-C lamp installation | $280-$520 |
Does UV light actually prevent mold in Manassas ducts?
It prevents mold growth on the coil and in the immediate plenum where the lamp shines, but it does not treat debris deeper in the duct runs. We install UV as a maintenance tool after cleaning, not as a substitute for it.
Is mold in ducts common in Manassas?
More common than in drier climates. The combination of 130°F attic temperatures, humid outdoor air, and aging flex-duct liners creates condensation points we find in roughly one-third of Manassas homes over 20 years old. We photograph every suspected area before recommending treatment.
Brands We Service in Manassas
We stock parts and service equipment from Honeywell, Aprilaire, Rotobrush, and Guardsman. Most common filter sizes, UV lamps, and plenum fittings are on the truck, so Manassas jobs rarely wait for a parts run. our brands
