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 Potomac
Air duct cleaning in Potomac, MD typically costs $450-$900 for a full system on a single HVAC unit, with larger estate homes running higher. Most Potomac jobs take 4-7 hours and are scheduled within 5-10 days. CleanRun Air Duct Cleaning serves every Potomac neighborhood, from River Road corridor estates to homes near the C&O Canal. We show up with a camera before we show up with a price, and every duct run gets photographed before and after. Call (806) 606-6902 for a written estimate with no vague ballparks.
What makes Potomac different is not the number of homes. It’s the scale of them. We routinely work in houses where the duct system runs 300-500 linear feet across multiple zones, original to construction, and touched exactly once since the Carter administration. That changes how we quote, how we clean, and what we document. More on that below.
Why CleanRun Air Duct Cleaning Is Potomac’s Preferred Air Duct Cleaning Company
CleanRun has been independent since 2013, and in that time we’ve cleaned ducts in more than 52,000 homes. Potomac represents a meaningful share of that number. The homes off River Road, Persimmon Tree Road, and Bradley Boulevard are exactly the kind of large, custom-built properties where our approach matters most. These are not tract houses with predictable six-run systems. They’re 6,000-10,000 square foot colonials and Tudors with multiple air handlers, finished attic ductwork, and decades of deferred maintenance. Our crews know what they’re going to find before the first access panel comes off, because we have seen the same patterns hundreds of times in this ZIP code.
Every CleanRun technician is background-checked, uniformed, and identified by name before arrival. We operate under the H.A.V.E.N. Standard, and Haven Standard Clause 1 is simple: a written price before any work starts. No exceptions. Potomac homeowners tend to be detail-oriented, they read the quote line by line, and they ask good questions. We would rather spend twenty minutes walking you through a camera inspection than rush a signature. Tomas Reyes, the owner, built CleanRun on the premise that a duct cleaning company should be able to prove its work. In Potomac, where the houses are large and the stakes are high, that proof is the product.
Our Air Duct Cleaning Services in Potomac

Residential Duct Cleaning
For Potomac homeowners, residential duct cleaning here means working on systems that are larger and older than almost anywhere else in Montgomery County. We clean the full duct run on each HVAC system, from the supply plenum to every register, using negative-pressure extraction with HEPA filtration. Camera inspection before and after is standard. A 9,000-square-foot colonial off Persimmon Tree Road that we worked on recently had three separate HVAC systems, two of them original to the house. The homeowner had lived there eleven years and never seen the inside of a supply duct. The camera showed a 3-inch debris build-up at the first elbow of the main trunk line. That’s not unusual in Potomac; it’s the baseline.

Commercial Duct Cleaning
Potomac’s commercial footprint is smaller than its residential one, but the buildings that exist along River Road and the commercial pockets near Seven Locks Road are often older structures with ductwork that predates modern filtration standards. We clean commercial duct systems for offices, medical suites, and small retail spaces. The process is the same as residential in principle, but the scheduling is different. Commercial work in Potomac typically happens after hours or on weekends to avoid disrupting business operations. Written scope, written price, documented photo record. Same standard, every time.

Supply Duct Cleaning
Supply ducts carry conditioned air from the furnace or air handler to each room. In Potomac’s estate homes, supply runs are often 40-70 feet long, running through finished attics and crawlspaces where leaks at the seams pull in insulation, dust, and outdoor particles. We see pine pollen layered inside supply ducts in Potomac more than any other suburb we serve. It’s not a vague observation. It’s what the camera shows, job after job. Supply duct cleaning on a multi-zone Potomac home often reveals collapsed flex sections or torn fiberglass lining that a homeowner would never know about otherwise.

Return Duct Cleaning
Return ducts are the intake side, and in Potomac they are frequently the dirtiest part of the system. Large, widely spaced returns in oversized homes draw air through less-than-airtight connections in attic installations. What gets drawn in stays. Leaf particulates, pollen, and fine dust accumulate in return cavities and reduce airflow across the evaporator coil. If the return side is clogged, the whole system works harder and the house does not get comfortable. We clean return ducts as their own scoped job when that is what the inspection calls for, and as part of every full system cleaning.

Before
AfterVideo Inspection: The Part Most Companies Skip
In Potomac, skipping video inspection is malpractice. Here is why: the duct runs are long, they wind through finished attics and crawlspaces, and they are old. Hidden tears in flex duct, collapsed sections, or delaminated fiberglass lining are common. A company that runs a brush through without looking first, or without showing you what the camera sees, is guessing. We do not guess. Air Duct Cleaning at CleanRun always starts with a camera. The inspection is documented, the findings are explained in plain language, and the decision to clean or replace is made with evidence in front of both of us.
This matters especially in Potomac because of water. After a storm, a homeowner may call about musty air and be told the ducts just need a cleaning. Sometimes that is true. Sometimes the fiberglass lining has absorbed moisture and delaminated, and cleaning those ducts spreads spores instead of removing them. The camera tells us which situation we are in. We will show you the footage.
When Water-Damaged Ducts Can Be Cleaned vs. When They Must Be Replaced

This is the page on our site where we take this on directly, because Potomac’s geography makes it a recurring issue. The Potomac River valley traps humidity, the tree canopy suppresses airflow, and storm water finds its way into attics and crawlspaces that were never sealed properly. When a duct gets wet, the question is not “can you clean it?” It is “is the duct material still intact?”
Here is the difference. If the duct is sheet metal with a light surface film of dust and a small, recent water intrusion that has dried completely, cleaning is usually sufficient. We sanitize with an EPA-registered antimicrobial after source removal, and the camera verifies no visible biological growth remains. That is a cleanable duct.
If the duct is fiberglass-lined and the lining is saturated, swelled, or delaminating from the sheet metal, cleaning is not the answer. The lining cannot be restored once it has absorbed enough water to separate. Running a brush over delaminated fiberglass shreds it further and releases fibers into the air stream. The correct action is replacement of the affected duct sections. We will tell you that flat, and we will put it in writing. Companies that recommend cleaning water-damaged fiberglass ducts are either not looking or not telling. Either way, you are paying for work that makes the problem worse.
The documentation matters for insurance. If you file a claim after a Potomac storm, your insurer wants to see evidence: photos of the water intrusion, camera footage of the duct interior showing saturated lining, and a written scope of work stating what can be cleaned and what must be replaced. We provide all of it. The before-and-after camera record from a CleanRun job is not a courtesy. It is a deliverable you can hand to your adjuster.
Common Air Duct Cleaning Problems We See in Potomac Homes
- Pine pollen and leaf particulate loading in return ducts. The wooded lots near the C&O Canal and along River Road produce enormous quantities of pollen each spring. Return ducts with leaky attic connections pull that pollen in and layer it inside the cavity and across the blower motor. We routinely remove several pounds of compacted debris from systems that have gone 20-30 years untouched.
- Delaminated fiberglass lining in original ductwork. Homes built between the late 1960s and early 1990s with original fiberglass-lined ducts are common in Potomac. Decades of humidity and thermal cycling cause the lining to break down. If it is merely dirty, we clean it. If it has separated from the metal, we document it and quote replacement.
- Collapsed flex duct in finished attic installations. Flex duct has a usable lifespan, and it does not age well in unconditioned attics. We find collapsed or kinked sections on long runs that make the whole branch line ineffective. Cleaning a collapsed duct is pointless. The camera finds it, and the repair is scoped separately.
- Multiple HVAC systems with uneven maintenance history. Large Potomac estates often have two or three systems. In our experience, one gets filter changes and occasional attention, and the others get forgotten. Each system gets its own inspection, its own cleaning quote, and its own photo record. One flat price per system, agreed in writing before work starts.
Trusted Brands We Service in Potomac

We use professional-grade equipment from manufacturers you can look up independently. Our agitation and extraction equipment includes Rotobrush and Nikro systems, and we carry Guardsman sanitizing solutions for post-cleaning treatment. We also work on systems from Honeywell, including air cleaners and filtration units that sit inline with residential ductwork. When a Potomac home has a Honeywell media filter housing or an Aprilaire unit installed, we clean and service the surrounding ductwork to manufacturer specifications. We do not make performance claims beyond what the manufacturer states. We simply use equipment that is built for this work and document what it does inside your ducts.
Pricing for Air Duct Cleaning in Potomac, MD
Here are the numbers, because Haven Standard Clause 1 says the price goes in writing before the work does, and we would rather you see the range before you call. A single HVAC system in a typical Potomac home runs $450-$650 for a full system cleaning with video inspection and photo documentation included. A large estate home with two systems typically runs $800-$1,100. A house with three systems, which we see regularly along Persimmon Tree Road and Bradley Boulevard, runs $1,200-$1,600. These are whole-system prices, not per-vent prices that quietly multiply. The written quote you receive is the price you pay. Not a starting figure.
What affects cost: number of HVAC systems, total length of duct runs, accessibility of the air handler and plenum, and whether the job includes sanitizing or duct repair.

FAQs - Air Duct Cleaning in Potomac

We run a camera through the duct and look at the lining material. Sheet metal ducts with a surface film and a dry water stain from a past leak are usually cleanable. Fiberglass-lined ducts where the lining has swelled, separated, or turned spongy must be replaced. Cleaning delaminated fiberglass spreads fibers and spores instead of removing them. We will show you the footage and give you a written recommendation either way. Call (806) 606-6902 to schedule an inspection.
Each HVAC system is an independent loop: its own air handler, its own supply trunk, its own return path. Cleaning one system does nothing for the other two. In Potomac estates with 6,000+ square feet, we commonly see one system maintained regularly while the others are ignored for decades. Every system gets its own inspection, its own scope, and its own fixed price. You agree to each price in writing before any work starts on that system.
The river valley traps moisture and the tree canopy suppresses airflow, so summer humidity inside return ducts stays higher here than in Bethesda or Rockville. That moisture accelerates biological growth inside fiberglass linings and turns ordinary dust into a damp, compacted sludge. Many Potomac homes benefit from a cleaning every 3-5 years instead of the 5-7 year interval that works in drier communities. The camera tells us more than the calendar.
Yes. We provide a written scope of work, camera footage of the duct interior before and after, and photographs of the affected areas. If water intrusion damaged fiberglass lining or caused mold growth inside the ductwork, that is documented in a format an adjuster can use. This is a standard part of every CleanRun job in Potomac, not an add-on. When you need documentation to stand behind, we give it to you because you already paid for it.
Access is the main challenge. Finished attic duct runs are often installed in cavities that are difficult to reach without cutting access panels. We scope the access requirements during the initial inspection and include any necessary access panels in the written quote before work starts. Long flex runs through finished attics are also where we most often find kinks, tears, and collapsed sections. If the camera finds them, we document them and quote repair separately. We do not clean a duct we know is broken and call it done.
