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.
Air Duct Cleaning in Germantown, MD
HVAC cleaning in Germantown typically runs $320-$580 for a whole-system job, with most homes in the 2,000-3,200 square foot range falling toward the middle. We schedule by appointment, arrive with a written price before touching any equipment, and deliver a documented photo record of every duct run when we leave. Call (240) 771-1508 to set up a free estimate.
The humid Piedmont summers and heavy pollen loads from mature oak and maple plantings accelerate what we find inside: debris buildup at low-point sags, mold in torn flex sections, and supply registers choked with accumulated allergen deposits. Our crews coordinate dispatch from the Washington, DC office and serve Germantown with Rotobrush and Abatement Technologies equipment sized for these tight interior partition-wall runs.
Why Germantown Homes Are Different
Germantown was developed as a Maryland “planned new town,” and that planning shows in the ductwork. Communities like Churchill Village, Gunners Lake Village, and Kingsview were built to density goals with builder-grade flex duct routed through interior walls and utility closets rather than accessible attics. Many runs are difficult to reach with standard equipment and require flexible tools or additional access panels.
The humid Mid-Atlantic climate compounds the problem. Summer relative humidity regularly exceeds 70%, and condensate pools in low-point sags where flex duct has degraded. Spring pollen from mature community plantings deposits heavily each season. In 1980s townhome developments, return-air pathways were often undersized to minimum builder specs, relying on gap-return through door undercuts. The supply ducts get the visible debris, but much of the dirty air moves through wall cavities no cleaning will reach. Our techs flag this proactively so homeowners understand what duct cleaning can and cannot address.
Our Main Germantown Services
Homeowners in Germantown call us most often for these three services:
Air Duct Cleaning in Germantown
We clean the full duct network, supply and return, using negative-pressure extraction with Rotobrush contact agitation. In Germantown’s partition-wall runs, we often cut additional access panels to reach debris trapped at elbows and sags. Every run is photographed before and after. Air Duct Cleaning in Germantown includes the documented photo record as standard.

Dryer Vent Cleaning in Germantown
Clogged dryer vents are a fire hazard and efficiency drain. In Germantown’s townhome clusters, long vent runs through shared walls are common and prone to lint accumulation at turns. We clear the full run from appliance to termination, photograph the obstruction, and verify airflow with a meter. Dryer Vent Cleaning in Germantown is quoted with a written price before work starts.

Duct Repair & Sealing in Germantown
Aging flex duct in Germantown’s original housing stock tears, sags, and separates at joints. We repair or replace damaged sections and seal leaks with mastic and metal-backed tape, not duct tape. Access is often limited in these interior-wall systems, so we plan the scope with the homeowner before cutting panels. Duct Repair & Sealing in Germantown carries the 365-Day Done Right Promise.

Before
AfterHVAC Cleaning in Germantown

HVAC cleaning in Germantown addresses equipment that has run 30 to 45 years in original housing stock, often without proper maintenance. The humid summers load evaporator coils with biological growth, while blower assemblies accumulate debris that reduces airflow and strains compressors. We clean the full mechanical system, not just ducts, using Abatement Technologies and Guardsman equipment. HVAC Cleaning from CleanRun includes the documented photo record and written price before any work begins.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or musty odors when the AC cycles on indicate a dirty coil.
What it costs in Germantown
Evaporator coil cleaning in Germantown typically ranges from $180 to $340.
How we do it
We access the coil through the plenum (the main air distribution box), apply foaming cleaner, rinse with low-pressure water, and photograph before and after.
Blower Cleaning
Signs you need it
Longer heating or cooling cycles, vibration noise from the air handler, or dust puffing from registers at startup point to blower debris.
What it costs in Germantown
Blower cleaning in Germantown typically ranges from $160 to $290.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the fan, and reinstall with torque verification.
What HVAC Cleaning Costs in Germantown
| Item | Typical range in Germantown |
|---|---|
| Evaporator coil cleaning | $180 - $340 |
| Blower cleaning | $160 - $290 |
| Full HVAC system cleaning (coil, blower, air handler) | $320 - $580 |
How do I know my HVAC system needs cleaning, not just the ducts?
If your registers blow clean air but cycles run long, humidity stays high, or energy bills spike, the mechanical components need attention. Call (240) 771-1508 for a free inspection.
Can HVAC cleaning fix uneven temperatures between rooms?
Sometimes. Restricted coils or weak blowers reduce airflow to distant runs, but duct design flaws in Germantown’s builder-grade systems may also be the cause. We diagnose before quoting.
Air Quality & Sanitizing in Germantown

Air quality and sanitizing in Germantown targets the biological load that thrives in 30- to 45-year-old flex duct during humid Piedmont summers. Mold, bacteria, and accumulated pollen degrade indoor air and trigger respiratory symptoms. We treat the source, not the symptom, with application equipment from Guardsman and Abatement Technologies. Air Quality & Sanitizing includes pre- and post-treatment photos and a written scope before application.
Mold Treatment
Signs you need it
Visible mold around registers, musty odors that intensify when the system runs, or recent water intrusion into ductwork indicate active growth.
What it costs in Germantown
Mold treatment in Germantown typically ranges from $280 to $520.
How we do it
We apply an EPA-registered fungistat to affected duct runs, fog the plenum with Abatement Technologies equipment, and verify with post-treatment photos.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, chronic allergy symptoms indoors, or a system located in a damp basement or crawl space suggest UV would help.
What it costs in Germantown
UV light installation in Germantown typically ranges from $340 to $680.
How we do it
We mount a UV-C lamp in the supply plenum, wire to the blower circuit for automatic operation, and show the homeowner the installation photo.
What Air Quality & Sanitizing Costs in Germantown
| Item | Typical range in Germantown |
|---|---|
| Mold treatment | $280 - $520 |
| UV light installation | $340 - $680 |
| Whole-system sanitizing (mold + bacteria + odor) | $380 - $720 |
Is mold treatment safe for kids and pets?
We use EPA-registered products applied to duct interiors only, with a recommended 2-hour ventilation period post-treatment. The product dries inert on surfaces.
How long does UV light last before replacement?
Lamps typically maintain effective output for 9,000 to 12,000 hours, roughly 12 to 18 months of continuous operation. We note install date on the job record.
Brands We Service in Germantown
We stock parts and service equipment from Aprilaire, Honeywell, and other major manufacturers. Most replacement components are available within 24 to 48 hours for Germantown appointments. See our brands for the full list.
