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.

AfterTrusted Air Duct Cleaning for Rockville Homeowners
Air duct cleaning in Rockville typically costs $380-$780 for a complete residential system, and every CleanRun job starts with a written price before any work begins. We’ve served Rockville homeowners since 2013, documenting the inside of every duct run with before-and-after photos as standard practice. Call (240) 255-4519 for a free estimate with no obligation to book.
Rockville’s housing stock tells its own story. The split-levels and colonials built during the 1960s and 1970s in neighborhoods like Twinbrook and Lincoln Park still run their original galvanized ductwork, while the newer construction in King Farm and Fallsgrove uses flexible duct board that collects debris differently at each joint. We’ve cleaned ducts in more than 52,000 homes, and the pattern in Rockville is consistent: older homes near the Metro corridor show heavy particulate buildup from decades of use, and newer homes often have construction debris the original builder never removed. Our crews carry Rotobrush and Nikro equipment sized for both conditions, and every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews.
What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Residential duct cleaning covers the complete network of supply and return runs, plenum (the central distribution box), and registers in single-family homes, townhomes, and condominiums. In Rockville, we most often service homes between 1,800 and 4,200 square feet with systems that haven’t been cleaned in 8-15 years. Our crew photographs every duct run before touching it, then uses negative-pressure extraction (a powerful vacuum that pulls debris toward the collection unit while agitation tools loosen buildup) to remove accumulated dust, pollen, and particulate matter. The photo record is delivered as a standard job deliverable, not an upsell.
Commercial Duct Cleaning
Commercial duct cleaning addresses the larger-diameter systems found in Rockville’s office parks, retail spaces, medical offices, and multi-tenant buildings along Rockville Pike and near the I-270 corridor. These systems move significantly more air volume and often contain specialized filtration or fire suppression components that require different handling than residential work. We schedule commercial jobs to minimize disruption to business operations, and our written scope specifies exactly which zones will be cleaned, the equipment to be used, and the documentation deliverables. Haven Standard Clause 1 applies: the price is fixed in writing before any panel is removed.
Supply Duct Cleaning
Supply ducts carry heated or cooled air from your HVAC unit to each room, and they’re the runs most homeowners notice first when dust starts blowing from vents. In Rockville’s older homes with rigid metal supply lines, we often find narrow sections where decades of accumulation have reduced airflow by 20-30 percent. Our technicians access each supply run through the register opening or an appropriately placed service port, then use mechanical agitation combined with negative-pressure extraction to restore designed airflow capacity. The before-and-after photos show the exact location and extent of buildup in each run.
Return Duct Cleaning
Return ducts pull air back toward the HVAC unit for reconditioning, and because they operate under suction rather than pressure, they collect larger debris that supply lines often miss. Pet hair, drywall dust, and in some Rockville homes near construction zones, fine silt from disturbed ground, all accumulate in return pathways. These runs are typically larger in diameter and may include filter housings or fresh-air intakes that require separate attention. We clean the complete return path including the filter rack area, and we note in the written job record if the filter type or installation is contributing to premature duct contamination.
Full System Cleaning
Full system cleaning is the complete service: every supply run, every return run, the plenum, the filter housing, and the accessible portions of the air handler cabinet. This is what most Rockville homeowners need when they haven’t had professional duct cleaning in 10 years or more, or when they’re moving into a previously owned home with no maintenance records. The full system service includes our complete photo documentation package, the written scope of work, and the 365-Day Done Right Promise. If any portion of the cleaned system shows workmanship issues within one year, we return and correct it at no charge.
Video Inspection
Video inspection uses a borescope camera (a flexible fiber-optic device with a lighted tip) to examine the interior condition of ductwork without disassembling the system. We recommend this service when a homeowner suspects damage, blockage, or contamination in a specific run that standard cleaning may not address, or when a real estate transaction requires documented evidence of system condition. In Rockville’s competitive housing market, we’ve provided video inspection reports for sellers in neighborhoods like Woodley Gardens and Potomac Woods who want to demonstrate maintenance diligence to prospective buyers. The video file is delivered as part of the job record.

Brands We Service for Air Duct Cleaning
We’ve cleaned and maintained ductwork connected to Honeywell air cleaning systems in hundreds of Rockville homes, particularly the electronic air cleaners and media filters common in 1990s and 2000s construction. Our technicians understand how these components interface with the duct network, and we inspect the filter housing and contact points as part of any connected duct cleaning service. The same applies to Aprilaire whole-home humidifiers and ventilation systems, which we regularly encounter in the larger homes of North Bethesda and the Montrose area; we check for moisture-related contamination in connected duct runs and document our findings in the written report.
Abatement Technologies HEPA filtration and containment equipment is part of our standard inventory for jobs requiring enhanced particulate control, such as homes with allergy-sensitive occupants or post-renovation cleaning. We’ve also serviced ductwork connected to Nikro portable extraction units in commercial settings where localized containment is necessary. Whether your system includes these brands or any other make, we can clean the connected ductwork, document the results, and flag any component issues we observe during the service.

AfterSigns You Need Air Duct Cleaning Right Now
- Visible dust blowing from registers when the system starts. This indicates loose debris in the supply lines that the airflow is dislodging, and it means the particulate is circulating through your living space before settling on surfaces. In Rockville’s dry winter heating season, this symptom often becomes more pronounced as the system runs longer cycles.
- Uneven heating or cooling between rooms that used to be consistent. When duct runs become partially blocked with accumulation, airflow to distant registers drops first, creating temperature stratification you can feel. We’ve restored balanced airflow in Rockville homes where the upstairs bedrooms had become unusable in summer because the return lines were choked with debris.
- Musty or stale odors when the HVAC system cycles on. Organic material in ductwork, including dust mite debris, pet dander, and in humid conditions, microbial growth on accumulated dirt, produces characteristic odors when disturbed by airflow. The smell is the debris becoming airborne, which means you’re breathing it.
- Excessive dust accumulation on furniture despite regular cleaning. If you’re dusting weekly and the film returns within days, your ducts may be acting as a reservoir that continuously reintroduces particulate. This is especially common in Rockville homes with original ductwork that has never been professionally cleaned.
- Recent renovation or construction work without post-project duct cleaning. Construction dust is fine, abrasive, and penetrates duct systems even when registers are covered. We’ve extracted significant drywall compound and insulation fragments from Rockville homes where the homeowner assumed the HVAC was protected during a kitchen or basement remodel.
Our Air Duct Cleaning Process - Step by Step
- 1
Written estimate delivered on-site. Our technician arrives at the scheduled time, inspects your accessible ductwork, and provides a fixed written price before any work begins. Haven Standard Clause 1 requires this; there is no “call for a quote” option because the price depends on what we find in your specific system.
- 2
Photo documentation of every duct run before cleaning. Using a borescope camera, we photograph the interior condition of each supply and return run, the plenum, and any accessible air handler components. These images become the “before” portion of your documented photo record, and we show them to you before proceeding.
- 3
Negative-pressure extraction with mechanical agitation. We connect a high-capacity vacuum to the main trunk line, creating suction throughout the system, then use compressed-air whips, rotary brushes, or other agitation tools appropriate to your duct material to loosen debris so the vacuum can capture it. The equipment is sized to your home; a 1,200-square-foot condo in Rockville Town Center requires different handling than a 5,000-square-foot home in Croydon Park.
- 4
Component cleaning and inspection. Registers, grilles, and accessible filter housings are removed and cleaned separately. We inspect the plenum for integrity issues, check sealant condition at joints, and note any damage or deterioration that could affect system performance. These observations are recorded in writing.
- 5
Post-cleaning photography and deliverables. Every run is photographed again to demonstrate the change. You receive the complete photo record, the written scope of work, and the 365-Day Done Right Promise documentation before our technician leaves. Payment is processed only after you’ve reviewed these materials and confirmed satisfaction.
How Much Does Air Duct Cleaning Cost in Rockville?
A typical residential full system cleaning in Rockville runs $380-$780 for homes between 1,500 and 3,500 square feet, with most single-family homes in neighborhoods like College Gardens and New Mark falling in the $480-$620 range. Smaller systems in townhomes or condos typically start at $340-$450, while larger homes with complex duct layouts or multiple HVAC zones can reach $850-$1,200. Commercial systems are priced by scope and require an on-site evaluation.
Several factors move the price within these ranges. The number of duct runs matters more than square footage; a 2,500-square-foot home with 18 runs costs more to clean thoroughly than a similarly sized home with 12. Accessibility affects labor time: ductwork in finished basements with drop ceilings is easier to service than lines buried behind drywall. The condition of the system also matters; heavy accumulation requiring extended agitation time, or the presence of construction debris or pest evidence, may extend the service scope.
To avoid overpaying, reject any quote that isn’t itemized in writing, and be wary of per-vent pricing structures that obscure the total cost. CleanRun’s price is one flat rate per system, agreed before work starts, with no additional charges for “extra” runs discovered mid-job. Our free estimate puts this number in writing with no obligation to book. Call (240) 255-4519 to schedule.

Frequently Asked Questions - Air Duct Cleaning in Rockville
Air duct cleaning is the mechanical removal of accumulated dust, debris, and particulate matter from the interior surfaces of your HVAC duct network, including supply runs, return runs, and the central plenum. Our process removes the visible buildup that restricts airflow and recirculates through your living space, documented with before-and-after photos of every run. We do not apply chemical treatments or “sealants” as part of standard cleaning; if microbial growth is present, we note it in the written report and discuss appropriate remediation options separately.
A complete residential system cleaning in Rockville typically takes 3-5 hours for a single-zone home, and 5-7 hours for larger homes with multiple HVAC units or complex duct layouts. Commercial jobs vary by scope and are estimated individually. The time includes setup, the complete cleaning process, post-service photography, and delivery of your documented photo record. We do not rush; Haven Standard Clause 1 pricing means the job is done thoroughly, not quickly.
Most Rockville homeowners pay between $380 and $780 for a complete residential system cleaning, with the majority of single-family homes falling in the $480-$620 range. The exact price depends on system size, number of duct runs, accessibility, and contamination level, which is why we provide a written, fixed price on-site before any work begins. Call (240) 255-4519 for a free estimate at your Rockville home.
Yes. We regularly clean ductwork connected to Honeywell electronic air cleaners and media filters, Aprilaire humidifiers and ventilators, and systems with Abatement Technologies HEPA components. Our technicians inspect the interface between these devices and your ductwork as part of the service, and we note any maintenance issues in the written job record. If your system includes a brand we haven’t specifically named, we can still clean the connected ductwork and document its condition.
We do not offer same-day or emergency dispatch for air duct cleaning; this is a scheduled service that requires proper equipment loading, crew assignment, and on-site evaluation for accurate pricing. For urgent air quality concerns, such as post-fire smoke damage or water intrusion affecting ductwork, we can often schedule within 24-48 hours. All calls are answered by a live person, 24/7, who can assess urgency and assign the earliest appropriate appointment.
Every job is backed by the 365-Day Done Right Promise: if any portion of our work is found deficient within one year, we return and correct it at no charge. This is a written guarantee included with your job documentation, not a policy subject to manager approval. The promise covers workmanship; it does not cover new contamination occurring after the cleaning, which is why we note system conditions and maintenance recommendations in your written report.
Clear a path to your HVAC equipment and the registers in each room; our technicians need workspace around the air handler and safe access to each vent. Remove fragile items from shelves near registers, as the vibration from agitation tools can cause light objects to shift. We will move and replace furniture that blocks register access if needed, and we protect flooring with drop cloths. Pets should be secured in a separate area during the service. Our technician will confirm specific preparation needs when confirming your appointment.
