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 Silver Spring, MD
HVAC cleaning in Silver Spring typically costs $350-$850 for a full system, and most jobs are scheduled within a week. The 1950s-1970s split-levels and Cape Cods that dominate Kemp Mill, Four Corners, and Woodside still run original sheet-metal ductwork that has never been opened, while summer humidity at 85-95% RH turns those aging interiors into active mold sites. CleanRun crews work Silver Spring from our Washington, DC dispatch office; call (240) 255-4519 for a written estimate before any work starts.
Why Silver Spring Homes Are Different
Silver Spring’s housing stock was thrown up fast during the postwar boom along Georgia Avenue and Colesville Road, and the construction shortcuts of that era are still breathing inside the walls. Many 1960s split-levels in Kemp Mill and Four Corners used open joist bays and hollow stud cavities as return-air pathways instead of actual ductwork. Those cavities are now packed with blown insulation fibers, rodent debris, and sixty years of settled dust that a standard flex-hose machine cannot touch without interior access cuts.
The climate makes it worse. Summer dew points in the low-to-mid 70s°F mean any duct leak, clogged drain pan, or oversized AC unit short-cycling leaves standing condensation on metal walls. Spring delivers one of the East Coast’s heaviest tree-pollen loads, and low-mounted return intakes pull that pollen plus crawlspace mold spores straight into the system. Newer outer-ring suburbs like Germantown do not face this pairing of aging infrastructure and extreme moisture load.
Our Main Silver Spring Services
Most Silver Spring homeowners who call CleanRun start with one of these three jobs.
Air Duct Cleaning in Silver Spring
We clean supply and return duct runs, registers, and the plenum (the main distribution box) using negative-pressure extraction with Rotobrush and Nikro equipment. In Silver Spring’s 1950s-1970s homes, we regularly find rectangular sheet-metal runs with deteriorating fiberglass duct-wrap shedding particles into the airflow. Every job ends with a Documented Photo Record of every run, before and after. Air Duct Cleaning in Silver Spring covers full-system pricing and what we find in local homes.
Dryer Vent Cleaning in Silver Spring
Dryer vent blockages in Silver Spring’s older split-levels often occur at the mid-wall elbow where the vent turns from vertical to horizontal, a spot lint accumulates for years before the dryer overheats. We run a rotary brush through the full line to the exterior termination and verify airflow with a meter. Dryer Vent Cleaning in Silver Spring details fire-risk specifics for Montgomery County housing stock.
Duct Repair & Sealing in Silver Spring
Original sheet-metal joints in Silver Spring’s postwar homes were sealed with fabric-backed tape that has dried and failed; we find 15-30% leakage at joints and seams on most inspections. We seal with mastic and metal-backed tape, then pressure-test to verify. Duct Repair & Sealing in Silver Spring explains how sealing cuts energy loss and humidity intrusion.

AfterHVAC Cleaning in Silver Spring
Full HVAC cleaning in Silver Spring addresses components the standard duct cleaning leaves behind: the evaporator coil caked with microbial growth from summer condensation, the blower wheel throwing dust back into cleaned ducts, and the air handler cabinet harboring standing water. Our HVAC Cleaning service treats these as a single system because re-contamination is guaranteed if one component is cleaned while another remains loaded. In Silver Spring’s climate, a cleaned duct system connected to a moldy coil is a waste of money.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, musty smell when AC cycles on, or cooling that cannot keep up on humid July afternoons in Silver Spring.
What it costs in Silver Spring
Evaporator coil cleaning runs $180-$340 as a standalone service, or $120-$220 when bundled with full duct cleaning.
How we do it
We remove the access panel, apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water capture, and photograph the coil before and after through the borescope.
Blower Cleaning
Signs you need it
Dust puffing from registers immediately after the system cycles on, or a blower wheel visible through the filter slot that looks like a felt drum.
What it costs in Silver Spring
Blower cleaning costs $150-$280, with tighter pricing for newer ECM motors that require careful re-balancing.
How we do it
We pull the blower assembly, clean the wheel and housing with compressed air and contact vacuum, check amp draw on reassembly, and record the before-and-after photo.
What HVAC Cleaning Costs in Silver Spring
| Item | Typical range in Silver Spring |
|---|---|
| Evaporator coil cleaning (standalone) | $180-$340 |
| Blower cleaning | $150-$280 |
| Full HVAC cleaning (coil + blower + air handler) | $350-$650 |
How do I know the coil is actually dirty if I can’t see it?
We show you. Every CleanRun HVAC cleaning includes borescope photos of the coil surface delivered before we quote the work. If the coil is clean, we say so and charge nothing for that component.
Will cleaning the coil fix my humidity problem?
It helps, but it is not the whole answer. A dirty coil cannot transfer moisture efficiently; however, Silver Spring’s extreme outdoor humidity also requires proper system sizing and sealed ducts. We assess all three and write what we find.
Air Quality & Sanitizing in Silver Spring
Air quality work in Silver Spring targets the microbial load that humidity and old ductwork create together. The same 1950s-1970s homes with original sheet-metal runs and failed fiberglass wrap are growing active mold colonies inside the plenum and at duct elbows where condensation pools. Our Air Quality & Sanitizing service applies EPA-registered treatments and installs preventive hardware because killing mold without fixing the moisture source guarantees regrowth in this climate.
Mold Treatment
Signs you need it
Visible black or green growth at registers, a wet-cardboard smell when heat or AC runs, or family members with year-round respiratory symptoms that worsen at home.
What it costs in Silver Spring
Whole-system mold treatment runs $400-$900 depending on colony extent and whether access cuts are needed to reach cavity returns.
How we do it
We apply an EPA-registered botanical fungistat to all interior duct surfaces through negative-pressure fogging, then install a dehumidistat-controlled vent or recommend UV prevention based on what the moisture meter shows.
UV Light Installation
Signs you need it
Recurring mold after professional cleaning, or a system located in a damp crawlspace or basement common in Four Corners and Woodside homes.
What it costs in Silver Spring
UV-C lamp installation at the coil or plenum costs $280-$550 including the lamp, housing, and electrical connection.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp at the coil face or supply plenum, wire to the blower circuit for automatic operation, and show you the installation photo in your job record.
What Air Quality & Sanitizing Costs in Silver Spring
| Item | Typical range in Silver Spring |
|---|---|
| Mold treatment (whole system) | $400-$900 |
| UV light installation | $280-$550 |
| Bacteria sanitizing (standalone) | $200-$400 |
Is the mold treatment safe for kids and pets?
Yes. We use EPA-registered botanical products, not bleach or quaternary ammonium compounds. The system is ventilated before we leave, and we document the product SDS in your job record.
How long does UV light actually last?
The lamp degrades to about 60% output after 9,000 hours, roughly one year of continuous operation. We note the install date in your record and call to schedule replacement; the housing stays, only the bulb changes.
Brands We Service in Silver Spring
CleanRun stocks filters, coils, and UV lamps for Honeywell, Aprilaire, and Abatement Technologies systems, with most common parts on the truck. If your air handler or purifier runs a less common brand, we source within 48 hours and still quote the full repair in writing before ordering. our brands

FAQs About Air Duct Cleaning in Silver Spring
No permit is required for standard residential duct cleaning or HVAC maintenance in Montgomery County. Duct modifications, new installations, or mold remediation involving structural access may require county inspection; we handle permit documentation if your job crosses that line and note it in the written scope.
We schedule most Silver Spring appointments within 4-6 business days. If you have active mold with photo documentation or a completely blocked HVAC system, we prioritize and often slot within 48 hours. We do not promise same-day dispatch because proper containment setup cannot be rushed.
Yes. The mid-rise and high-rise buildings near the Metro use shared HVAC risers and individual fan-coil units, which require different access protocols than single-family ductwork. We coordinate with building management for riser shutoff windows and clean individual units with portable negative-pressure machines that do not affect neighboring systems.
