Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents

Worth knowing

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 Before & After in Rockville, MD

We’ve cleaned ducts in Rockville since 2013, and we’ve learned that claims don’t mean much without proof. Every job we finish includes a Documented Photo Record, before and after, of every duct run. Below are representative projects showing what we actually found, what the equipment showed, and what the homeowner received in writing. These aren’t stock photos. They’re the standard deliverable on every CleanRun visit.

Heavy Debris Build-Up in Twinbrook Ranch-Style Supply Trunk

Before: heavy debris accumulation in main supply trunk, Twinbrook area, Rockville
Before: Main supply trunk, 14-inch rectangular galvanized steel, first section after plenum (the air distribution box connected to your furnace). Camera shows 2- to 3-inch debris layer including drywall dust from 2019 renovation and compressed fiberglass fragments.
After: same trunk cleared to bare metal, negative-pressure extraction completed
After: Trunk cleared to bare metal with Rotobrush contact cleaning followed by Nikro negative-pressure extraction (a high-powered vacuum that pulls dislodged material downstream, preventing recontamination). Photo record shows clean metal at 6-foot, 12-foot, and 18-foot inspection points.

The homeowner in Twinbrook, Rockville, had scheduled service after noticing dust reappearing on furniture within 48 hours of cleaning. Our camera showed the debris build-up at the first elbow, 8 feet from the plenum. The restriction was reducing airflow to three downstream bedrooms. We delivered a written scope and price before removing the first panel, completed the cleaning in one visit, and the photo record documented bare metal at every access point. The homeowner’s written job record included 23 before-and-after images.

Pet Dander Saturation in King Farm Townhome Return System

Before: pet hair and dander coating inside 10-inch round return duct, King Farm, Rockville
Before: 10-inch round return duct, flex-line section between main trunk and bedroom register (the visible vent cover where air enters the room). Coating of pet hair and fine dander, approximately 1/4-inch thick, adhered to duct walls with biological film.
After: same return duct after Abatement Technologies HEPA-contact cleaning and sanitizing
After: Duct walls restored to original polymeric liner with no visible residue. Abatement Technologies HEPA-contact cleaning followed by Guardsman antimicrobial application (an EPA-registered treatment that addresses microbial growth in HVAC systems, applied according to manufacturer specification).

This King Farm townhome in Rockville had two golden retrievers and a cat, with the return system pulling dander directly past the air handler. The camera showed the biological film at the flex-line junction. We quoted a written price for full return-system cleaning plus register-level sanitizing before any work started. The photo record showed the coating removal at each of four bedroom returns. The homeowner received the complete image set and a written 365-Day Done Right Promise.

Construction Dust Compaction in Fallsgrove Renovation

Before: compacted drywall dust and joint compound in supply branch, Fallsgrove, Rockville
Before: 6-inch supply branch to master bedroom, Fallsgrove home renovated in 2022. Compacted drywall dust and joint compound fragments forming a solid mass at the second elbow, reducing effective diameter by approximately 40%.
After: same branch fully cleared, airflow restored to design specification
After: Branch fully cleared with mechanical agitation and negative-pressure extraction. Airflow at register restored to design specification, verified with anemometer (a handheld device measuring air velocity in feet per minute) before crew departure.

The Fallsgrove homeowner in Rockville had completed a basement-to-master-suite renovation two years prior and never had the ducts cleaned afterward. Our camera found the compaction at the second elbow, 14 feet from the plenum. The mass was dense enough to resist standard vacuum suction alone. We wrote the scope and price before starting, used mechanical agitation to break the compaction, and verified airflow restoration with an anemometer reading at the register. The photo record included the anemometer display in the final image set.

Mold-Like Staining in Woodley Gardens Older Home

Before: dark staining on interior of fiberboard duct, Woodley Gardens, Rockville
Before: Interior of fiberboard duct trunk, Woodley Gardens home built 1987. Dark staining consistent with moisture intrusion and organic growth, concentrated on lower surface where condensation had pooled due to missing insulation wrap.
After: staining removed, fiberboard treated, insulation wrap replaced
After: Staining mechanically removed from fiberboard surface, treated with antimicrobial application per manufacturer specification, and missing insulation wrap replaced with closed-cell sleeve to prevent future condensation accumulation.

The Woodley Gardens home in Rockville had a musty odor that intensified when the AC cycled on. Our inspection found the missing insulation wrap and the resulting condensation pool. We documented the staining with the camera, delivered a written price for cleaning plus insulation repair before any treatment began, and completed the work with the antimicrobial application. The photo record showed the before condition, the cleaned surface, and the replaced insulation. We recommended a follow-up humidity assessment, which the homeowner scheduled separately.

Register Blockage in Rockville Town Center Apartment Conversion

Before: register grille and immediate duct section blocked by paint and debris, Rockville Town Center
Before: Register grille and first 18 inches of duct section, Rockville Town Center apartment converted to condo in 2021. Multiple layers of paint overspray from unit renovation, plus construction debris including broken drywall anchors and plastic fragments.
After: register and duct section cleared, grille cleaned or replaced as needed
After: Duct section cleared to bare metal, register grille removed and cleaned or replaced as needed, with new hardware and proper seal at floor interface.

This Rockville Town Center unit had weak airflow at two registers despite a new HVAC system. Our camera found the blockage within the first 18 inches, paint overspray from the conversion renovation gluing debris to the duct walls. We wrote the price for register-level cleaning and minor hardware replacement before starting. The photo record documented the blockage removal and the restored airflow. The homeowner received the image set showing the same duct section from the same camera angle, before and after.

General Maintenance Cleaning in Lincoln Park Single-Family

Before: moderate dust accumulation in supply system, Lincoln Park, Rockville, after 7 years without service
Before: Moderate dust accumulation throughout supply system, Lincoln Park single-family home, 7 years since prior cleaning. No blockages or damage, but measurable debris layer reducing system efficiency and contributing to dust recirculation.
After: supply system restored to clean condition, full photo record delivered
After: Supply system restored to clean condition with full contact cleaning and negative-pressure extraction. Full photo record delivered showing clean metal at plenum, trunk, branch, and register access points.

The Lincoln Park homeowner in Rockville called for routine maintenance, no complaints, just due diligence after seven years. Our inspection found no emergencies, which we stated plainly. We delivered the written price for standard whole-system cleaning before any work started, completed the service in one visit, and provided the full photo record showing clean metal at every documented point. This is what preventive maintenance looks like when there’s nothing to exaggerate.
