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
HVAC cleaning in Rockville typically runs $400-$800 for a complete system, with most jobs scheduled within a week and completed in a single visit. Rockville’s split housing stock - 1950s Twinbrook ramblers with original sheet-metal ducts, 1970s garden apartments along Veirs Mill Road, and newer King Farm townhomes with flex-duct - means no two jobs present the same contamination pattern or access challenge. We’re CleanRun Duct Repair & Cleaning, and we dispatch crews to Rockville from our Washington, DC office. Call (240) 255-4519 for a written estimate before any work starts.
Why Rockville Homes Are Different
Rockville sits in Montgomery County’s humid continental zone, where summer dew points climb above 65°F for weeks and the urban tree canopy dumps oak and tulip poplar pollen loads among the heaviest in the Maryland suburbs. That pollen doesn’t stay outside; it pulls into return-air systems through low-positioned grilles, especially in Twinbrook’s 1950s ramblers where floor-level returns were standard.
Those same Twinbrook homes were built for federal workers with minimal duct insulation. Many later had carports enclosed as garages, placing return plenums adjacent to combustion sources. The result: denser debris loads than we find in North Pike or King Farm developments. Meanwhile, 1990s-2000s communities like Fallsgrove used flex-duct prone to joint separation and liner deterioration. Same city, three distinct mechanical eras, three distinct cleaning protocols.

AfterHVAC Cleaning in Rockville
HVAC cleaning in Rockville addresses the contamination that accumulates in components the homeowner never sees: the evaporator coil above the furnace, the blower wheel that moves all conditioned air, and the condenser outside that rejects summer heat. In Twinbrook’s uninsulated plenums and King Farm’s tight mechanical closets, these components foul faster than in newer, better-sealed systems. Our HVAC Cleaning service covers the full system, not just the ducts.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from registers, or musty odors when the AC first cycles on in Rockville’s humid summers.
What it costs in Rockville
Evaporator coil cleaning in Rockville typically runs $250-$450, depending on access and contamination severity.
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 for the job record.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating or cooling across rooms, or dust puffing from registers when the system starts.
What it costs in Rockville
Blower cleaning in Rockville typically runs $200-$350, with additional charges only if the motor requires extraction from a tight mechanical closet.
How we do it
We remove the blower assembly, clean the wheel blades with compressed air and solvent, vacuum the housing, balance the assembly, and document with photos.
What HVAC Cleaning Costs in Rockville
| Item | Typical range in Rockville |
|---|---|
| Evaporator coil cleaning | $250-$450 |
| Blower cleaning | $200-$350 |
| Full HVAC system cleaning (coil, blower, condenser) | $400-$800 |
How do I know my HVAC components are actually dirty?
We show you. Every HVAC cleaning includes a Documented Photo Record of each component before and after work, delivered as part of the standard job record - Haven Standard Clause 2. Call (240) 255-4519 to schedule an inspection.
Can HVAC cleaning fix weak airflow in my Rockville home?
It often does, if the restriction is a fouled coil or clogged blower rather than duct leakage or undersizing. We diagnose the cause before quoting any work, per Haven Standard Clause 1. Call (240) 255-4519 for a written assessment.
Air Quality & Sanitizing in Rockville
Rockville’s high summer humidity and dense pollen loads create conditions where mold colonizes uninsulated duct liners and bacteria proliferate on wet evaporator surfaces. In Twinbrook’s 1950s systems with original fiberglass lining, we regularly find active mold growth at the first elbow downstream of the coil. Our Air Quality & Sanitizing service treats biological contamination with documented results, not chemical fogging and hope.
Mold Treatment
Signs you need it
Musty odors when the HVAC cycles, visible discoloration on register boots, or recent water intrusion in the mechanical area.
What it costs in Rockville
Mold treatment in Rockville typically runs $300-$600 for localized application, or $800-$1,500 for whole-system remediation with multiple contaminated runs.
How we do it
We apply an EPA-registered antimicrobial to affected duct surfaces, HEPA-vacuum debris, and verify treatment with post-application photos of each treated run.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, chronic musty odors, or a household member with documented mold sensitivity.
What it costs in Rockville
UV light installation in Rockville typically runs $400-$800 for a single lamp at the coil, including hardware and electrical connection.
How we do it
We mount a UV-C lamp in the supply plenum aimed at the coil surface, wire to the blower circuit for automatic operation, and verify lamp output with a radiometer.
What Air Quality & Sanitizing Costs in Rockville
| Item | Typical range in Rockville |
|---|---|
| Mold treatment (localized) | $300-$600 |
| Mold treatment (whole system) | $800-$1,500 |
| UV light installation | $400-$800 |
Does UV light actually prevent mold in Rockville’s humid climate?
UV-C at the coil surface prevents mold colonization there, but it does not treat existing duct contamination or address humidity at its source. We install UV as part of a documented protocol, not a standalone fix. Call (240) 255-4519 for a written scope.
Is mold in ducts common in older Rockville homes?
Yes, particularly in Twinbrook and West End ramblers with uninsulated fiberglass duct liners and high summer humidity. We document it with photos, treat only confirmed growth, and show you the evidence before quoting. Call (240) 255-4519.
