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.
Fast, Reliable Air Duct Cleaning Across North Potomac
Air duct cleaning in North Potomac typically runs $425-$685 for a full system on a 3,000-5,000 sq ft colonial, with the job taking four to seven hours depending on zone count and access. That’s the number CleanRun puts in writing before a single panel comes off, under Haven Standard Clause 1. North Potomac’s housing stock is nearly all large production-built colonials and transitionals from 1985-2005, and those homes have specific duct problems: long flex runs, degraded liners, and years of pollen packed into joints that were never sealed right in the first place. Our crews serve North Potomac locally, and dispatch coordinates from the Washington, DC office. Call (806) 606-6902 and you’ll get a live person, not a recording.
Why CleanRun Air Duct Cleaning Is North Potomac’s Preferred Air Duct Cleaning Company
North Potomac homeowners tend to research before they call. They want to see the inside of their ducts, not hear a pitch about how dirty they probably are. That’s how we’ve always worked. Since 2013, CleanRun has completed 52,000+ jobs, every one with a written price before work started and a Documented Photo Record when the crew left. The camera doesn’t lie, and neither does the invoice.
Tomas Reyes founded CleanRun on a simple observation: the duct cleaning industry had a credibility problem built on $79 coupons and shop-vac noise. His answer was documentation. Every duct run is photographed before and after. Every job includes a written scope and a written warranty, the 365-Day Done Right Promise. If it’s not right, we make it right. Not subject to a manager’s mood. It’s in writing.
Our technicians are background-checked, uniformed, and identified by name before arrival, under Haven Standard Clause 3: Verified Crews. They carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, tools you can look up independently. We don’t use hardware-store gear and we won’t pretend a shop vac is a negative-pressure extraction system.
Our Air Duct Cleaning Services in North Potomac

Every North Potomac job starts the same way: a camera goes into the plenum and we see what’s actually there before we touch anything. Here’s what that looks like across the services we run most often in this area.
Residential Duct Cleaning
Most North Potomac homes are center-hall colonials with two or three HVAC zones and extended flex-duct runs. We clean the full length of every supply and return run, the trunk line, the plenum, and the registers. The photo record shows every run, not a sampling. For a typical 4,000 sq ft home near the Seneca Creek corridor, expect a four to six hour job.

Commercial Duct Cleaning
North Potomac has a small but real commercial footprint: medical and dental offices near Travilah Road, retail suites, and professional buildings. We schedule around business hours and document the work the same way we do in homes, because commercial property managers in Montgomery County need the photo record for their own files.

Supply Duct Cleaning
Supply ducts in North Potomac’s 1990s-era homes carry a specific risk: flex-duct liner degradation. The liner inside the flex run breaks down after 25-35 years and sheds particulate into the air stream every time the blower cycles. A camera inspection shows whether the liner is shedding, intact, or collapsed. If it’s collapsed, cleaning alone won’t fix it, and we’ll tell you that plainly before quoting a repair or replacement.

Return Duct Cleaning
Return ducts pull air back toward the air handler, and in North Potomac homes built in the 1990s, they also pull in attic dust and insulation through improperly sealed joints at the trunk connections. That debris ends up coating the coil and blower motor. Cleaning the return side and sealing those joints is one of the highest-value things we do, because it addresses the source, not just the symptom.

Full System Cleaning
This is the job most North Potomac homeowners eventually need: every supply run, every return run, trunk, plenum, coil, and blower. Full-system cleaning includes source removal with negative pressure, meaning debris is extracted from the system, not just loosened and pushed around. For a three-zone colonial with a finished basement bonus room at the end of a 38-foot flex run, this is the only approach that actually clears the accumulated pollen load.

Video Inspection
A camera inspection is the single most important step in North Potomac duct cleaning, because 25-35 year old flex duct looks fine from the register. The camera shows what’s actually inside: liner degradation, collapsed sections, debris compaction at elbows, and joints that were never sealed. We don’t quote a cleaning without one. If a competitor quotes you without scoping the system, you should ask why.

AfterTrusted Brands We Service in North Potomac
We work on systems from every major manufacturer, and we’re familiar with the Honeywell and Aprilaire zone controllers and filtration components common in North Potomac’s production-built colonials. Our equipment roster includes Rotobrush and Abatement Technologies machines, and we use Guardsman products for sanitizing when the job calls for it. We don’t play brand games or pretend one name is magic. We just know these systems well enough to clean them without damaging the old flex liner that’s already fragile.
Common Air Duct Cleaning Problems We See in North Potomac Homes

- Long flex runs with collapsed liners. Homes off Dufief Mill Road and Travilah Road routinely have 30-40 foot flex runs serving bonus rooms and finished basements. We’ve pulled collapsed liner sections out of these runs more times than we can count. The air stops moving, the room never cools right, and the musty smell hangs around.
- Pollen paste hardened inside attic ducts. The oak and maple canopy near Seneca Creek State Park dumps a massive pollen load every spring. In hot-humid summers, condensation forms inside attic duct runs, the pollen sticks to the wet interior, and over years it hardens into a paste that restricts airflow and makes the AC work harder.
- Improperly sealed joints from the original build. Production builders in the 1990s left joints at trunk connections unsealed after the rough inspection. Negative pressure from the air handler pulls attic dust and insulation into the return side, which coats the coil and blower motor. This is a source problem, not a cleanliness problem.
- Flex-duct liner shedding fiberglass. The inner liner on 25-35 year old flex duct degrades and sheds fibers into the air stream. You can’t see it from the register. You need a camera to confirm it, and that finding changes the recommendation from cleaning to repair or replacement.
Pricing for Air Duct Cleaning in North Potomac, MD
A full system cleaning on a 3,000-5,000 sq ft North Potomac colonial typically runs $425-$685, including the camera inspection and the complete Documented Photo Record. Smaller single-zone homes or condos fall in the $300-$425 range. Homes with four or more zones, finished basements, or long flex runs at the far end of the house can push toward $700. What moves the number is not square footage alone; it’s zone count, access difficulty, and how much debris is actually packed into the runs. We’ll put the exact price in writing before work begins, every time. If you bring a competitor’s written estimate, we’ll put our own number next to it in writing, free. Call (806) 606-6902 for an exact quote.

FAQs - Air Duct Cleaning in North Potomac

A 30-40 foot flex run changes the physics of cleaning. Debris accumulates far from any access point, and the sagging low points trap pollen and dust that agitation tools have to work much harder to reach. Standard cleaning equipment designed for short, rigid runs will miss the far end entirely. We use extended agitation tools and run negative pressure the full length of the run. Call (806) 606-6902 and we’ll explain exactly what your system requires.
Sometimes yes, sometimes no, and you won’t know which until a camera goes in. Flex duct liners from the 1990s are often degraded to the point where aggressive cleaning would tear them further. We inspect first, then recommend cleaning if the liner is intact or repair/replacement if it isn’t. We will not sell you a cleaning that damages your system. That’s why the camera inspection comes first.
Pollen enters through outdoor air intakes and open windows, then gets pulled into the return side and distributed through the supply side. North Potomac’s dense mature tree canopy, especially near the Seneca Creek corridor, produces some of the heaviest seasonal pollen accumulation in Montgomery County. That pollen settles deep into long duct runs and, combined with summer condensation in attic ducts, hardens into a paste that restricts airflow. It’s a compounding problem that a simple vacuum pass won’t fix.
Yes. Shared dryer vent stacks accumulate lint from multiple units, and one clogged section affects every home connected to that stack. North Potomac’s townhome and condo associations are responsible for the common portion of the vent, but individual units still need their section cleaned regularly. We document the before and after of every section we clean, which is useful for HOA disputes. Call (806) 606-6902 to schedule.
A camera inspection is a scoped video record of the inside of your duct runs. It shows liner condition, debris accumulation, joint sealing, and collapsed sections. In North Potomac, where 25-35 year old flex duct is standard, the camera is how we distinguish between a cleaning problem and a repair problem before we quote a dollar amount. It’s included with every job, and the photo record belongs to you as part of the standard job file.
