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 runs $380-$620 for a whole-system job, with air quality and sanitizing services adding $240-$480 depending on whether mold treatment or UV installation is needed. Silver Spring’s post-war housing stock and humid subtropical climate create conditions we don’t see in drier suburbs: panned joist returns packed with decades of debris, evaporator coils coated in microbial growth from July humidity above 70%, and pollen loads from the oak-heavy urban forest band that matches Rock Creek Park. We dispatch crews from our Washington, DC office and carry Rotobrush and Abatement Technologies equipment sized for the tight crawl spaces and original sheet-metal trunk systems common in Kemp Mill and Four Corners. Call (240) 363-3380 for a written price before any work starts.
Why Silver Spring Homes Are Different
Silver Spring sits in a humid subtropical pocket where July relative humidity regularly exceeds 70%, and unconditioned attic and crawl-space duct runs sweat through the summer. That moisture makes mold colonization inside ductwork far more common here than in drier Mid-Atlantic suburbs. The residential core, particularly Kemp Mill, Four Corners, and Woodmoor, is dense with 1950s-1970s split-levels and cape cods built with panned joist returns: floor joists or wall stud bays used as return-air plenums instead of sheet-metal ducts. These 50-to-70-year-old cavities have never been cleanable by standard methods and accumulate decades of debris, rodent droppings, and mold, yet most homeowners have no idea they exist. The heavily wooded neighborhoods also feed exceptionally high spring tree-pollen loads directly into outdoor air intakes. When we open a system in Silver Spring, we expect to find conditions that require explanation before any work begins.
Our Main Silver Spring Services
Silver Spring homeowners call us most often for these three services, each with its own dedicated page:
Air Duct Cleaning in Silver Spring
We clean the full duct network in Silver Spring’s post-war ranches and split-levels, including original sheet-metal trunk-and-branch systems and 1980s flex-duct add-ons in finished basements. Every run is photographed before and after. Panned joist returns in Kemp Mill and Woodmoor homes are flagged for remediation discussion when found. Air Duct Cleaning in Silver Spring covers full pricing and what the photo record includes.
Dryer Vent Cleaning in Silver Spring
Dryer vent blockages are common in Silver Spring’s older garden-style condos along Colesville Road and in single-family homes with long vent runs through humid crawl spaces. We remove lint buildup with Nikro equipment and verify airflow at termination. Dryer Vent Cleaning in Silver Spring has full details on the process and written pricing.
Duct Repair & Sealing in Silver Spring
Sealing disconnected flex-duct and repairing corroded sheet-metal seams is standard work here, especially in homes with 1980s basement additions where original trunks were extended with poorly supported flex runs. We document every repair with before-and-after photos. Duct Repair & Sealing in Silver Spring explains the full scope.

BeforeAfterHVAC Cleaning in Silver Spring
Silver Spring’s post-WWII housing stock, combined with humidity-driven microbial growth and pollen infiltration from the oak-heavy urban forest, means HVAC components here degrade faster than in drier climates. Evaporator coils in Kemp Mill and Four Corners homes routinely show biofilm buildup that restricts airflow and drives up energy bills. HVAC Cleaning addresses the full system, not just the ducts.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from registers, or a musty smell when the AC cycles on in July.
What it costs in Silver Spring
Evaporator coil cleaning in Silver Spring typically runs $180-$340.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the result.
Blower Cleaning
Signs you need it
Vibration noise from the air handler, uneven heating or cooling across rooms, or dust puffing from registers at startup.
What it costs in Silver Spring
Blower cleaning in Silver Spring typically runs $160-$280.
How we do it
We remove the blower assembly, clean blades and housing with compressed air and solvent, balance the wheel, and document with photos.
What HVAC Cleaning Costs in Silver Spring
| Item | Typical range in Silver Spring |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $160-$280 |
| Condenser cleaning | $140-$220 |
How do I know if my HVAC needs cleaning or just the ducts?
If your Silver Spring home has weak airflow, musty AC smells, or ice on refrigerant lines, the HVAC components need separate attention from duct cleaning. Call (240) 363-3380 and we’ll inspect both systems and put a written price to each.
Can HVAC cleaning reduce my summer electric bill?
Yes, a clean evaporator coil and blower can restore airflow efficiency lost to biofilm and dust, which is significant in Silver Spring’s humid summers. Call (240) 363-3380 for a written estimate.
Air Quality & Sanitizing in Silver Spring
Silver Spring’s 70%+ summer humidity and panned joist returns create conditions for mold and bacteria that standard duct cleaning cannot address alone. The same Kemp Mill and Four Corners homes with hidden stud-cavity returns often show elevated spore counts that require targeted treatment, not just vacuum extraction. Air Quality & Sanitizing covers the full range of remediation options.
Mold Treatment
Signs you need it
Visible mold around registers, persistent musty odor after duct cleaning, or moisture stains on ceiling panels below duct runs.
What it costs in Silver Spring
Mold treatment in Silver Spring typically runs $280-$520.
How we do it
We apply EPA-registered antimicrobial through the duct system, treat affected panned returns directly, and provide lab-verifiable before-and-after documentation.
UV Light Installation
Signs you need it
Recurring mold after treatment, family members with humidity-aggravated respiratory symptoms, or chronic mustiness in summer months.
What it costs in Silver Spring
UV light installation in Silver Spring typically runs $320-$580.
How we do it
We mount a UV-C lamp in the supply plenum, wire to the blower circuit, and verify irradiance at the coil surface with a meter.
What Air Quality & Sanitizing Costs in Silver Spring
| Item | Typical range in Silver Spring |
|---|---|
| Mold treatment | $280-$520 |
| UV light installation | $320-$580 |
| Bacteria sanitizing | $240-$400 |
Does mold treatment require me to leave the house?
No, our antimicrobial application is contained within the duct system and vented before occupants return; we schedule Silver Spring jobs to minimize disruption. Call (240) 363-3380 to arrange timing.
How long does UV light installation take?
Most Silver Spring UV installations finish in two to three hours, including wiring to the blower circuit and irradiance verification. Call (240) 363-3380 for a written price.
