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.

Why Gaithersburg Homes Are Different
Gaithersburg sits at roughly 500 feet in the Piedmont, but summer dew points still hit the low-to-mid 70s°F. That humidity condenses inside duct runs passing through unconditioned attic knee-walls, a standard configuration in Montgomery Village townhomes built from 1967 through the 1980s. Those original fiberglass duct board liners, now 40-60 years old, delaminate inward and blow glass fibers and compacted debris into living spaces with every HVAC cycle.
Newer communities like Kentlands and Lakelands use flex duct prone to kinking and interior liner deterioration that traps debris. The housing stock here demands more labor-intensive access than detached suburban homes, and the microbial pressure from summer condensation makes cleaning urgent rather than cosmetic.
Our Main Gaithersburg Services
Homeowners in Gaithersburg call us most often for these three services:
Air Duct Cleaning in Gaithersburg
We clean every duct run with negative-pressure extraction, photographing the interior before and after. In Montgomery Village, we regularly find original fiberglass duct board shedding particles. Access through tight mechanical closets and knee-walls takes longer here than in newer detached homes. Air Duct Cleaning in Gaithersburg includes the full documented photo record as standard.
Dryer Vent Cleaning in Gaithersburg
Townhome configurations in Montgomery Village and Kentlands often route dryer vents through long horizontal runs with multiple elbows, creating lint traps that standard brushes miss. We use Rotobrush and Nikro equipment to clear the full run and verify airflow at termination. Dryer Vent Cleaning in Gaithersburg includes before-and-after photos of the vent interior.
Duct Repair & Sealing in Gaithersburg
Aging duct board in Montgomery Village and kinked flex duct in Kentlands both leak conditioned air into unconditioned spaces. We seal with mastic and metal tape, then pressure-test the system. Duct Repair & Sealing in Gaithersburg includes a written scope and the 365-Day Done Right Promise.

BeforeAfterHVAC Cleaning in Gaithersburg
Full HVAC Cleaning in Gaithersburg addresses the evaporator coil, blower, and condenser, components that accumulate debris faster here due to the combination of aging duct stock and summer humidity driving microbial growth.

The work is photographed at each stage and delivered as a documented photo record.

How we do it
We remove the access panel, apply foaming cleaner to the coil fins, rinse with low-pressure water, and photograph the before and after condition.

Air Quality & Sanitizing in Gaithersburg
Air Quality & Sanitizing in Gaithersburg targets the microbial growth that summer condensation breeds inside duct runs through unconditioned spaces. Montgomery Village’s original fiberglass duct board, now delaminating after 40-60 years, creates reservoirs for bacteria and mold that standard cleaning alone cannot address. We treat with EPA-registered products and verify results.
Mold Treatment
Signs you need it
Musty odors when HVAC runs, visible discoloration at registers, or recent water intrusion in the duct path.
What it costs in Gaithersburg
Mold treatment in Gaithersburg typically runs $220-$380 depending on affected duct length.
How we do it
We apply an EPA-registered antimicrobial to affected duct runs, treat the source moisture condition, and photograph verification swabs.
UV Light Installation
Signs you need it
Recurring microbial growth despite cleaning, or chronic musty odors in humid-summer operation.
What it costs in Gaithersburg
UV light installation in Gaithersburg typically runs $280-$450 per unit.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp at the coil or supply plenum, wire to the air handler, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Gaithersburg
| Item | Typical range in Gaithersburg |
|---|---|
| Mold treatment | $220-$380 |
| UV light installation | $280-$450 |
| Bacteria sanitizing (whole system) | $180-$280 |
Is mold in ducts common in Gaithersburg?
Yes, in Montgomery Village and similar 1960s-1980s stock where condensation collects in unconditioned knee-wall runs. Summer dew points in the low 70s°F accelerate growth. We treat with EPA-registered products and include verification in the photo record. Call (571) 520-6317 for inspection.
Do UV lights prevent mold from coming back?
UV-C lamps at the coil surface inhibit microbial growth there, but they do not clean existing debris or address moisture sources. We install Honeywell and Aprilaire units and specify what each model covers in writing.
