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.

AfterNikro HVAC Cleaning in Rockville: What to Know First
We provide independent Nikro HVAC cleaning in Rockville, typically completed in one scheduled visit with your written price delivered before any panel comes off. Most Nikro air handlers and coil assemblies we see in Rockville homes run between $340 and $680 for a full-system cleaning, depending on whether the blower compartment and evaporator coil both need attention. This page is for Nikro owners who want the work done without voiding their warranty, without per-vent pricing games, and with a photo record of what was actually inside their unit. Call (240) 255-4519 for a free estimate, or bring us a competitor’s written quote for a free second opinion under Haven Standard Clause 1.
How Nikro Products Fail - and How We Fix Them
- Nikro SL2000 Series blower motors seize from dust compaction on the squirrel-cage fins. The SL2000’s open-frame blower design pulls air through a narrow intake plenum (the main distribution box), and in Rockville’s pollen-heavy springs, that fine yellow-green dust packs between fin rows until the motor draws excessive amperage and trips thermal overload. We remove the blower assembly, photograph the fin blockage, clean with a Nikro-compatible negative-pressure extraction system, and meter the running amperage against the nameplate before reassembly.
- Nikro PD Series evaporator coils develop mold at the U-bend drain pan interface. The PD’s shallow drain pan sits at a slight backward pitch in some installations, and condensate pools where the copper U-bend meets the galvanized pan. In Rockville’s humid July-August stretches, that standing water breeds microbial growth that restricts airflow and produces a musty discharge from registers (the vent covers in each room). We treat the coil with an EPA-registered foaming cleaner, verify drain pan pitch with a level, and photograph the cleared condensate path.
- Nikro HV5000 heat exchanger cells accumulate combustion particulate in homes with aging oil-to-gas conversions. Rockville’s 1960s and 1970s split-levels near Congressional Plaza still run converted heating systems, and residual oil soot migrates into the HV5000’s cellular stainless heat exchanger. The particulate acts as an insulator, raising stack temperature and throwing off the pressure switch. We brush and vacuum each cell individually, pressure-test the exchanger assembly, and document the before-and-after stack temperature reading.
- Nikro FlexDuct adapters separate at the crimp ring on long horizontal runs. The FlexDuct system’s barbed crimp fitting relies on a single stainless clamp, and in Rockville attics that hit 140 degrees in August, the polymer adapter hardens and loses grip. We find this most often in the 1,800-square-foot ranches off Rockville Pike where the adapter sits above a hot garage ceiling. We replace with a heavy-duty worm-gear clamp and support the joint with a metal hanger to eliminate sag.
- Nikro CM2000 condenser coils clog with cottonwood seed and construction dust. Rockville’s spring cottonwood cycle overlaps with constant new development, and the CM2000’s wide-fin condenser (the outdoor coil) traps debris that insulates the refrigerant lines. Head pressure rises, efficiency drops, and the compressor cycles on thermal protection. We fin-comb the coil, apply foaming cleaner, and rinse with low-pressure water directed away from the electrical compartment.
Our Nikro HVAC Cleaning Process
- 1
Scheduled arrival, verified crew. Our technician arrives in a CleanRun uniform, background-checked under Haven Standard Clause 3: Verified Crews, and introduces himself by name before entering.
- 2
Visual inspection with photo documentation. We open the air handler or condenser cabinet and photograph every component we intend to clean. The photo comes first. The price comes after.
- 3
Written price delivered. Based on what the images show, we deliver a single flat price for the complete job. No per-vent add-ons, no equipment-access fees, no surprises. Haven Standard Clause 1.
- 4
Component removal and targeted cleaning. We use Nikro-compatible tools, including Rotobrush contact cleaning for blower assemblies and Abatement Technologies negative-pressure containment for coil work. OEM gaskets and seals are reused where serviceable; we note any that require replacement.
- 5
Reassembly, operational test, and final photo record. We run the system through a complete heating or cooling cycle, verify temperatures and pressures against Nikro specifications, and deliver your before-and-after photo record as a standard job deliverable.
- 6
365-Day Done Right Promise in writing. If anything we cleaned fails due to our workmanship within one year, we return and make it right. The guarantee is printed on your invoice, not just stated in conversation.

AfterWhat Nikro HVAC Cleaning Costs in Rockville
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Evaporator coil cleaning (Nikro PD/SL series) | $340 - $520 | Coil accessibility, mold treatment required, drain pan modification |
| Blower assembly cleaning (Nikro SL2000/HV5000) | $280 - $440 | Motor removal required, bearing condition, fin damage |
| Condenser coil cleaning (Nikro CM2000) | $220 - $380 | Fin combing required, refrigerant line insulation replacement |
| Full air handler cleaning (coil + blower + cabinet) | $520 - $680 | Combination of above factors, plus plenum sealing |
| Heat exchanger cleaning (Nikro HV5000) | $380 - $560 | Cell count, particulate density, pressure test result |
These are whole-system prices agreed in writing before work starts. We do not quote per-vent or per-register pricing. A competitor’s $79 coupon typically covers a visual inspection and surface vacuuming, not component-level cleaning.

Why Rockville Homeowners Call CleanRun Air Duct Cleaning Rockville for Nikro Work
We’ve been running jobs across Rockville since 2013, including plenty of work in the older split-levels near Congressional Plaza where original Nikro flex duct shows its age in ways that aren’t obvious until you pull the register cover. Tomas Reyes and our crew know the difference between an SL2000 and an HV5000 without checking the nameplate twice, and we carry the tools to service Lennox, Trane, and Carrier systems when a home has mixed equipment from a previous owner’s renovation.
Every job produces a Documented Photo Record of every duct run and component cleaned, delivered to you as a standard deliverable. The 365-Day Done Right Promise is printed on your invoice. Our license number is published on every page, not buried in a footer. And we are independently owned and operated, not a franchise, which means the person who quotes your job is accountable for the result.
FAQs
No, professional cleaning by an independent service provider does not void a Nikro warranty, provided the work does not alter factory specifications or use incompatible chemicals. We document our methods and materials on every invoice so you have a record if warranty questions arise later. Call (240) 255-4519 if you need specifics for your model year.
Replacement becomes the better option when the heat exchanger has pinhole corrosion, the blower motor draws more than 15% over nameplate amperage after cleaning, or the evaporator coil has fin deterioration exceeding 30% surface area. We photograph these conditions during inspection and show you the images before quoting either service. For a free second opinion on a replacement recommendation, call (240) 255-4519.
We stock common Nikro blower belts, drain pans, and gasket sets, and we source OEM heat exchanger cells and motor assemblies through our trade distributors with a 3-5 day typical turnaround. When an aftermarket part meets or exceeds OEM specification at lower cost, we present both options in writing with the warranty implication of each. Haven Standard Clause 1 applies to parts pricing too.
Every 3-5 years for homes without pets or respiratory sensitivities; every 2-3 years for homes with multiple pets, recent renovation dust, or occupants with allergies. Rockville’s pollen density and humid summers accelerate coil and blower loading compared to drier inland climates. We date-stamp your photo record so you have a baseline for the next decision. Call (240) 255-4519 to schedule an inspection and we’ll show you what your system actually looks like inside.
We clean and repair Lennox, Trane, Carrier, and Nikro systems, including hybrid installations where a previous owner matched a Nikro air handler to a different-brand condenser. Our technicians carry the coil-fin combs, pressure charts, and gasket sets for all four lines, so one visit handles the complete system. For a written quote on mixed-brand service, call (240) 255-4519.
