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 Rockville, MD
Full-system HVAC cleaning in Rockville typically runs $380-$680 for most homes, with older Twinbrook properties sometimes pushing higher due to access constraints and mixed-era ductwork. We coordinate scheduling from our Washington, DC office and dispatch crews to Rockville daily. Call (240) 771-1508 for a written estimate before any work starts.
Rockville’s housing stock creates conditions we don’t see elsewhere in Montgomery County. The 1949-1956 cape cods and ranches in Twinbrook carry original galvanized trunk lines now entering their eighth decade, while 1970s-era fiberglass flex-duct retrofits degrade in the city’s humid summers. Our crews document every duct run with before-and-after photography, part of the standard job record on every visit since 2013.
Why Rockville Homes Are Different
Twinbrook’s post-WWII tract development gives Rockville an unusual concentration of aging forced-air infrastructure. The original galvanized sheet-metal trunk lines, often routed through unconditioned attics and crawl spaces, accumulate fibrous debris across 65-75 years of operation. When 1970s energy-crisis upgrades grafted fiberglass-lined flex-duct take-offs onto those metal trunks, they created mixed systems vulnerable to collapse at the boot connections.
Rockville’s humid subtropical climate compounds the problem. Summer dew points in the 65-72°F range promote mold and mildew inside poorly sealed ductwork. The city’s mature oak and maple canopy drives a heavy spring pollen load that peaks March through May, accumulating in return-air systems and creating predictable seasonal IAQ complaints. This pairing of aging infrastructure and health-conscious, high-income residents, many federal agency and NIH-affiliated, produces demand for documented results rather than coupon-priced vacuum noise.
Our Main Rockville Services
Rockville homeowners contact us most often for these three services, each with its own dedicated page and local pricing.
Air Duct Cleaning in Rockville
We clean the full duct system, from plenum to register, using negative-pressure extraction with Rotobrush and Nikro equipment. In Rockville’s older homes, we pay particular attention to the transition points where 1950s metal trunk meets 1970s flex-duct, documenting each run photographically. Every job concludes with a written scope and the full photo record. Air Duct Cleaning in Rockville
Dryer Vent Cleaning in Rockville
Lint accumulation in dryer exhaust runs creates fire risk and extends drying cycles. We clean the full vent path from appliance to termination, photographing the obstruction before removal. Rockville’s older homes often have longer vent runs through finished basements or exterior walls that require specialized tools. Dryer Vent Cleaning in Rockville
Duct Repair & Sealing in Rockville
Disconnected boots, collapsed flex-duct, and deteriorating fiberglass liner are common findings in Twinbrook and East Rockville homes. We repair or replace damaged sections and seal leakage points with mastic and metal-backed tape, then pressure-test to verify. All repair work carries the 365-Day Done Right Promise.

BeforeAfterHVAC Cleaning in Rockville
Rockville’s aging mixed-era systems and humid summers make HVAC component cleaning a remediation necessity rather than optional maintenance. The evaporator coils in Twinbrook homes often sit above decades of debris-laden return air, while blower wheels in East Rockville split-levels accumulate pollen and mold spores through the March-May peak season. We clean these components as standalone jobs or as part of full-system service, with every step documented photographically. HVAC Cleaning covers our full methodology for homeowners researching before they call.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, reduced airflow from registers, or musty odors when the AC cycles on in Rockville’s humid July and August conditions.
What it costs in Rockville
Evaporator coil cleaning typically ranges $180-$340 in Rockville, with tighter-access attic installations in older homes at the higher end.
How we do it
We remove the coil assembly where accessible, apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water, and photograph the before and after condition for the job record.
Blower Cleaning
Signs you need it
Uneven heating or cooling across rooms, vibration or noise from the air handler, or visible dust puffing from registers at startup.
What it costs in Rockville
Blower assembly cleaning runs $160-$290 in Rockville, with multi-speed variable blowers in newer King Farm and Fallsgrove homes requiring additional disassembly time.
How we do it
We remove the blower wheel and motor assembly, clean blades and housing with compressed air and solvent, balance the wheel, and reinstall with torque verification.
What HVAC Cleaning Costs in Rockville
| Item | Typical range in Rockville |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower assembly cleaning | $160-$290 |
| Full HVAC cleaning (coil + blower + air handler) | $380-$680 |
Can HVAC cleaning reduce my summer energy bills in Rockville?
Yes, a clean evaporator coil and blower can restore 10-15% of lost cooling efficiency in humid climates like Rockville’s, where dirty coils force longer run times. The photo record shows exactly what was restricting airflow. Call (240) 771-1508 for a written estimate.
How do I know the HVAC cleaning was actually done?
Every HVAC cleaning includes a Documented Photo Record of the coil, blower, and air handler interior, delivered as part of the standard job record, not as an extra. Haven Standard Clause 1 requires the written price before work starts; Clause 2 requires the photo documentation before we leave.
Air Quality & Sanitizing in Rockville
Rockville’s humid summers and heavy spring pollen create conditions where mold, bacteria, and odors colonize duct interiors, particularly in Twinbrook’s aging systems with compromised seals. The city’s health-conscious demographic, heavy with NIH and federal agency employees, drives demand for measurable IAQ improvement rather than scented masking. We treat these problems with documented application protocols and post-treatment verification. Air Quality & Sanitizing details our full approach.
Mold Treatment
Signs you need it
Visible mold at registers or in the plenum, musty odors when the system cycles, or allergy symptoms that worsen in humid summer months.
What it costs in Rockville
Mold treatment for duct systems ranges $450-$890 in Rockville, with whole-system fogging of older Twinbrook homes at the higher end due to access complexity.
How we do it
We apply EPA-registered antimicrobial through the full duct system using Abatement Technologies fogging equipment, with dwell time per manufacturer specification, then verify with post-treatment moisture and visual inspection.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, persistent microbial odors, or family members with immunocompromised conditions requiring continuous air-stream sterilization.
What it costs in Rockville
UV-C light installation at the evaporator coil or air handler runs $320-$580 in Rockville, including the Honeywell or Aprilaire fixture and electrical connection.
How we do it
We mount the UV-C fixture with sight-line to the coil and drain pan, wire to a dedicated circuit, install a viewport for lamp inspection, and document intensity with a UV meter at commissioning.
What Air Quality & Sanitizing Costs in Rockville
| Item | Typical range in Rockville |
|---|---|
| Mold treatment (whole system) | $450-$890 |
| UV-C light installation | $320-$580 |
| Bacteria sanitizing with post-treatment verification | $280-$520 |
Does mold treatment eliminate all mold spores in my Rockville home?
No treatment eliminates 100% of spores, but our protocol reduces viable colony-forming units to levels consistent with outdoor air, verified by post-treatment inspection. The 365-Day Done Right Promise covers recurrence. Call (240) 771-1508 for a written scope and price.
How long does UV light installation take?
Most UV-C installations in Rockville homes take 2-3 hours, including electrical connection and commissioning verification; we schedule these as morning or afternoon appointments with the written price confirmed before arrival.
