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.

AfterFast, Reliable HVAC Cleaning Across Rockville
HVAC cleaning in Rockville means more than running a vacuum through a few registers. It means addressing years of accumulated debris inside the plenum, the coil, the blower wheel, and every duct run that carries conditioned air through your home. CleanRun Air Duct Cleaning provides that work with one difference: a written price before we start and a photographed record of every duct run when we leave. If you’re calling from Twinbrook, Woodley Gardens, Fallswood, or anywhere else in Rockville, reach us at (806) 606-6902.
Why CleanRun Air Duct Cleaning Is Rockville’s Preferred HVAC Cleaning Company
The homes we service in Rockville differ block by block. A 1958 rambler off Halpine Road in Twinbrook has nothing in common, duct-wise, with a 1980s colonial in Fallswood or a condo unit along Rockville Pike. We treat them accordingly. Our HVAC Cleaning team documents what the camera finds before any cleaning begins, so a homeowner can see the debris condition at the first elbow or the coil face, then compare it to the after photo. Tomas Reyes, who leads CleanRun, built the company around a simple rule: no claim that cannot be photographed or put in writing. Rockville homeowners appreciate that more than most. They have seen the $79 coupon van pull up and leave with a four-figure invoice. We show the written price, then we do the work.
The company was established in 2013 and has served more than 52,000 homes, each with a written price before work started and a documented photo record when the crew left. Dispatch and scheduling are coordinated from the brand’s Washington, DC office; crews serve Rockville locally. Our technicians are background-checked, uniformed, and identified by name before arrival, per Haven Standard Clause 3: Verified Crews.
Our HVAC Cleaning Services in Rockville
Evaporator Coil Cleaning
The evaporator coil sits above or beside the furnace and is where condensation forms every cooling season. In Rockville’s humid summers, that coil stays wet longer than in drier climates, which means dust sticks to it and bakes into a film that chokes airflow. A dirty coil forces the compressor to run longer and the blower to push harder. We clean coils with professional-grade equipment from brands like Rotobrush and Nikro, then photograph the coil face before and after. For older Rockville systems, especially in Twinbrook homes with original duct boots, coil cleaning is often the difference between a system that limps through August and one that holds temperature.
Blower Cleaning
The blower wheel moves air through your entire system. When it accumulates dust, pet hair, and the fine particulate that Rockville’s spring pollen loads leave behind, it spins out of balance and delivers less airflow per rotation. Blower cleaning in Rockville typically runs $150 to $300 depending on furnace accessibility and whether the wheel needs to be pulled from the housing. On split-levels and capes where the furnace is tucked into a half-height crawlspace or a closet off the living room, access time adds to the job. We quote that before we start, in writing.
Condenser Cleaning
The condenser is the outdoor unit. In Rockville, dense hardwood canopy release pollen in spring and early summer, and that pollen packs into condenser fins. Cottonwood seed, oak tassel, maple samaras, all find their way into the coil. A clogged condenser raises head pressure and shortens compressor life. Condenser cleaning in Rockville runs $120 to $250 for most single-unit residential systems. We wash fins with low-pressure water and approved coil cleaner, then check the refrigerant line insulation and clear the pad of debris.
Air Handler Cleaning
For condos and apartments along the Rockville Pike corridor near the Red Line Metro stations, the air handler is often a closet-mounted unit that pulls return air through one central grille. Those handlers collect dust on the blower, the secondary pan, and the interior cabinet surfaces. Air handler cleaning in Rockville runs $180 to $320 for standard residential units. Multiple-story condo buildings with shared return plenums can run higher because sealing off the trunk requires more labor. We photograph the inside of the handler cabinet as part of the standard job record.

BeforeAfterTrusted Brands We Service in Rockville
We clean systems built around Carrier, Trane, Lennox, Rheem, Goodman, and Bryant equipment, along with Aprilaire and Honeywell filtration components. For duct remediation and sealing, our crews use Abatement Technologies and Guardsman products. If we need to replace a section of flex duct or seal a plenum, the brand matches the job, not the other way around. We don’t push proprietary line replacements when a proper cleaning and sealing will restore function.
Common HVAC Cleaning Problems We See in Rockville Homes
- Slab-set duct boots in Twinbrook: Original 1950s-60s boots were set directly into concrete without sealed collars. Decades of soil moisture wick up into the supply runs, rusting the metal and pulling damp crawlspace air into the system. This failure mode is common enough in Twinbrook that it has become a standard part of the conversation when any cleaning job is booked there.
- Condensation on uninsulated crawlspace ducting: Rockville’s humid subtropical summers produce dew points high enough to condense water on any uninsulated galvanized surface. That moisture supports mold growth inside the duct, which then spreads toward supply registers. Cleaning alone won’t fix it; the duct needs sealing and the crawlspace needs a vapor barrier or insulation strategy.
- Return-air plenums packed with pollen: Rockville’s dense hardwood canopy dumps a heavy spring pollen load every year. That pollen overwhelms filters and accumulates in the return plenum, reducing airflow and forcing the blower motor to work harder until it overheats. We frequently pull two to three gallons of packed debris from a single return plenum in April and May.
- Disconnected flex joints in aging split-levels: In Fallswood and Woodley Gardens colonials from the 1970s-80s, flex duct connections to trunk lines loosen over decades of thermal cycling. Conditioned air leaks into unconditioned crawlspaces and attics while pulling dirty air back through the gaps. A camera inspection identifies every disconnected joint before we clean, because cleaning a disconnected run is wasted effort.
Pricing for HVAC Cleaning in Rockville, MD
A whole-system HVAC cleaning in Rockville runs $450 to $900 for a typical single-family home under 2,500 square feet. That includes the return plenum, supply trunk, all accessible duct runs, the evaporator coil, the blower wheel, and the register covers. Air handler cleaning runs $180 to $320. Condenser cleaning runs $120 to $250. Evaporator coil cleaning alone runs $180 to $340. Blower cleaning runs $150 to $300. Homes with original Twinbrook slab-set boots or heavily corroded galvanized runs may fall at the upper end of the range because sealing and minor repair work become part of the job. Every price is written before work starts, per Haven Standard Clause 1. There is no per-vent pricing and no coupon that turns into something else once the truck is parked.

FAQs - HVAC Cleaning in Rockville
Twinbrook’s original 1950s-60s cape cods and ramblers have galvanized ductwork that predates modern sealed-joint standards, and many boots are set directly into concrete slabs without sealed collars. That means soil moisture, crawlspace air, and decades of debris accumulate faster than in newer subdivisions with properly sealed systems. In Twinbrook off Halpine Road, our crew opened a supply register in a 1958 rambler and found the original sheet-metal boot had rusted through where it met the slab, pulling damp crawlspace air into the run. We isolated the branch with negative pressure, brushed out the debris, and used a camera inspection to confirm the disconnected flex joint before sealing the collar and treating the adjacent plenum with an EPA-registered antimicrobial. Call (806) 606-6902 for a written estimate specific to your home.
In multi-story condo buildings along Rockville Pike, dryer vents often share a common stack through the building. When one unit’s dryer vent is clogged, backpressure pushes lint and moisture into neighboring runs, including HVAC returns that share the same chase. Cleaning an HVAC system in a condo without addressing the shared vent stack leaves the job incomplete. We inspect the adjacent return plenum and the common vent chase where access allows, and we document what we find. Call (806) 606-6902 to schedule a camera inspection.
Yes. Apartment and condo HVAC systems in Rockville are often closet-mounted air handlers or small utility room furnaces, which require different tools than a full residential trunk system. Parking restrictions on narrow streets or in garage structures mean our crews bring only what the job requires, staged in a compact footprint. We schedule accordingly, and the written price accounts for access constraints before the crew arrives. Call (806) 606-6902 to discuss your building’s access situation.
Original galvanized ductwork in Rockville’s older homes frequently hosts mold growth from summer condensation, dust mite accumulation from humid crawlspace air, and rust particles from corroded seams and boots. These contaminants circulate through the supply registers and settle on surfaces. Cleaning removes the accumulated material; sealing the ducts and addressing the moisture source prevents recurrence. Call (806) 606-6902 for a written assessment.
Yes. We clean according to NADCA’s ACR standard, which covers the entire air conveyance system including the coil, blower, plenum, and duct interiors. The standard requires source removal, meaning debris is loosened and extracted under negative pressure, not pushed downstream. Our crews use Rotobrush and Nikro equipment to meet that requirement, and every job includes the documented photo record so you can verify what was actually removed. Call (806) 606-6902 for a written estimate.
