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.

Why CleanRun Air Duct Cleaning Is Gaithersburg’s Preferred Air Duct Cleaning Company
Gaithersburg’s housing stock is not like the rest of Montgomery County. Much of it was built between 1966 and the mid-1980s, and thousands of those original duct runs are still in service. Our Air Duct Cleaning crews know what a 1970s Montgomery Village flex-duct system looks like on the inside because we’ve documented thousands of them. We don’t guess at what you need. We put a camera inside the duct run, show you the before photo, and only then discuss what the work involves.
Every technician who arrives at a Gaithersburg address is background-checked, uniformed, and identified by name before stepping through the door. That’s Haven Standard Clause 3: Verified Crews. Our dispatchers coordinate from the brand’s Washington, DC office, and scheduling for Gaithersburg jobs runs six days a week. The 365-Day Done Right Promise applies to every job we perform here. If the work isn’t right, we make it right. In writing. Not subject to a manager’s mood.
Tomas Reyes leads the crews that serve Gaithersburg. He’s the person whose name goes on the job record, and he’s the one who reviews the photo documentation before you receive it. No mystery. No middleman.
Our Air Duct Cleaning Services in Gaithersburg

Residential Duct Cleaning
For single-family homes in Kentlands, Lakelands, and the older neighborhoods east of I-270, we clean the full duct pathway: supply registers, supply trunk, return risers, return plenum, and the main return drop. Gaithersburg’s freeze-thaw cycles and humid shoulder seasons mean condensation forms inside poorly sealed ducts more often than people realize. We document every run with before-and-after photos so you see exactly what was removed.

Commercial Duct Cleaning
Small office buildings, medical suites, and retail spaces in Gaithersburg’s commercial corridors off Shady Grove Road and Frederick Avenue have a different set of problems: higher static pressure, longer trunk runs, and rooftop units that pull in road dust. We schedule commercial jobs around your operating hours and provide the same documented photo record we give residential clients. Property managers appreciate the written scope because it stands up to tenant questions.

Supply Duct Cleaning
Supply ducts carry conditioned air from your furnace or air handler to each register. In Montgomery Village, many original supply runs are galvanized metal wrapped in fiberglass, and the joints were sealed with duct tape that hasn’t aged well. We use negative-pressure extraction with agitation tools sized for the duct diameter. The goal is source removal, not pushing debris further down the line.

Return Duct Cleaning
Return ducts pull air back to the blower, and they’re often the dirtiest part of the system because they carry unfiltered air. In garden condos along Montgomery Village Avenue, return ducts frequently run through shared attic chases that span multiple units. If a neighbor’s section is mold-contaminated, it can affect your air. We inspect the entire return path, not just the visible register, and we’ll tell you if the problem extends beyond your unit.

Before
AfterVideo Inspection: What You Get That Other Companies Don’t Show You
Most air duct cleaning companies in Gaithersburg will hand you a receipt and leave. We hand you a documented photo record of every duct run we touched, inside and out. A camera goes into the duct before cleaning, and again after. You see the plenum box. You see the trunk line. You see what came out. This isn’t a marketing gimmick. It’s evidence. If a contractor can’t show you the inside of your ducts, you have no way to verify the work happened at all. In Gaithersburg’s older communities, where flex-duct liners can hide mold and torn joints, this matters more than anywhere else.
Common Air Duct Cleaning Problems We See in Gaithersburg Homes

- Shared attic chases in Montgomery Village condos. Original duct runs were often routed through attic spaces spanning multiple units. One contaminated section affects the whole row. We’ve documented mold spreading through a shared return plenum that the HOA had classified as “common area” for years.
- Deteriorating duct-tape joints on original galvanized runs. The tape from the 1970s and 1980s fails first. Once it peels, conditioned air leaks into unconditioned space, pulls in attic dust, and raises humidity inside the duct. We see this on nearly every older Gaithersburg townhome we open.
- Fiberglass liner degradation from aggressive cleaning. Some companies use standard brushes on 50-year-old flex duct. That can tear the inner liner and blow fiberglass particles into your air. We use agitation tools matched to the material and camera-check every run before we touch it.
- Stacked return risers in garden apartments. A technician who only cleans the supply registers and skips the return riser leaves half the pathway untouched. In stacked buildings, the return riser can carry debris from every unit below you. We trace it end to end.
Trusted Equipment We Use on Gaithersburg Jobs
We don’t show up with a shop vac and a prayer. Our crews run professional-grade extraction and agitation equipment from manufacturers you can look up yourself: Rotobrush for flexible-line source removal, Nikro for HEPA-filtered negative air machines, and Honeywell for the filtration and IAQ components we install when needed. If a Gaithersburg contractor won’t name their equipment, that tells you something. We name ours in the written scope before work begins.
Pricing for Air Duct Cleaning in Gaithersburg, MD

Here are the real numbers for Gaithersburg’s market, not a teaser coupon that doubles once the van is in your driveway. A single-family home in Kentlands or the Goshen Road corridor typically runs $425-$690 for a full system clean. A townhome in Montgomery Village typically runs $380-$540. A garden condo off Montgomery Village Avenue is usually $350-$520, depending on the number of runs and whether the return plenum is shared. If your ducts haven’t been cleaned in 15 years, or if a camera inspection reveals heavy buildup, expect to be on the higher end.

The Shared-Duct Reality in Gaithersburg’s Condos and HOAs
Gaithersburg’s Montgomery Village is one of the largest planned residential communities in Maryland, built out between 1966 and the mid-1980s. What that means for duct cleaning is specific and it’s not something you’ll find in neighboring Rockville’s mixed-vintage subdivisions. In the older townhome rows, the original flex-duct trunk lines were often run through shared attic spaces spanning multiple units. A single mold-contaminated section can affect airflow and air quality across adjoining homes. Some HOAs classify the shared portion as common area. Others won’t touch it. Owners get stuck in the middle.
Our crew recently cleaned a 1970s garden condo off Montgomery Village Avenue where the return duct ran through a shared attic chase with the unit next door. We set up a Rotobrush system under full negative pressure and ran a camera inspection. The camera showed deteriorating duct-tape joints and mold on the fiberglass liner. We did source removal with HEPA-filtered agitation tools, then coordinated with the property manager to schedule the adjoining unit the same week. Their shared return plenum was pulling from the same compromised run. Cleaning only one side wouldn’t have fixed the air quality problem. This is the kind of job that defines Gaithersburg duct work.
If you live in a condo in Kentlands or a garden unit in Montgomery Village, the question of who’s responsible for which section matters. A supply register in your ceiling might be your problem. The riser between floors might be the HOA’s. We’ll document what we find and give you a written record you can take to a property manager or board meeting. You don’t need a contractor who shrugs. You need one who shows you the photo.
What Gaithersburg’s Climate Does to Your Ducts

Gaithersburg sits at about 500 feet of elevation in the Piedmont, noticeably cooler and more humid in spring and fall than areas closer to the Potomac. That humidity, combined with a long summer cooling season, drives condensation inside improperly sealed duct runs. Condensation inside a duct is a mold-amplification pathway. It’s physics, not scare tactics. Freeze-thaw cycles also stress the exterior envelope of older homes, opening small gaps where attic air gets pulled into the return path. Many Gaithersburg homeowners only notice the result: a musty smell when the AC kicks on, or visible dust on registers within days of cleaning.

FAQs - Air Duct Cleaning in Gaithersburg
The dryer vent that runs exclusively from your dryer to the exterior wall is typically the homeowner’s responsibility, even if the duct itself passes through shared structure. What complicates it in Montgomery Village is when the vent transitions into a common riser or chase that serves multiple units. In those cases, the HOA or condo association usually owns the shared portion. We can camera the full run and document exactly where the transition happens, so you know which portion is yours and which is the association’s. That documentation has settled more than a few disputes. Call (806) 606-6902 and we’ll schedule the inspection.
Yes, and in Gaithersburg’s stacked and garden-style buildings it’s a common finding. When the AC blower runs, it draws air through the return path under negative pressure. If that return path passes through a shared attic chase with mold conditions, the odor is pulled directly into your unit. A clean filter won’t help because the contamination is upstream of the filter. We’d start with a video inspection of the return run, document what the camera finds, and write up exactly what needs to happen, including any coordination with the property manager.
Supply-only cleaning addresses the ducts that carry conditioned air out to your registers. It doesn’t touch the return riser, the return plenum, or the air handler coil. In a stacked condo building, the return riser runs vertically between floors and can carry debris from every unit below. A full system cleaning includes the supply side, the return riser, the return plenum, and the air handler cabinet. If a company quotes you a low price for a “duct cleaning” in a stacked building, ask whether the return riser is included. If they can’t answer, they probably weren’t planning to clean it.
Yes. We clean what falls within your unit, and we document what falls outside it. The written scope will show which runs are yours and which are common. If the HOA is responsible for a section that’s affecting your air, you’ll have a photo record to support that conversation. We won’t touch common-area duct work without proper authorization, but we’ll give you the evidence you need to press the board. That’s what the documented photo record is for. Call (806) 606-6902 to schedule an inspection and we’ll map your system end to end.
Original flex duct from the 1970s is fragile, and aggressive brushing can tear the inner liner, sending fiberglass into your air stream. That’s not a theoretical risk; we’ve been called in to fix the aftermath from other companies’ work. The safe approach is a camera inspection first, then agitation matched to the liner condition, with HEPA-filtered negative pressure running the entire time. In many cases, the real problem isn’t dirt alone. It’s deteriorated duct-tape joints and liner breakdown. We document that on video. If the duct is too degraded to clean safely, we tell you before touching it, and we put repair options in the written scope.
