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.
Nikro HVAC Cleaning in Houston: What to Know First
CleanRun provides independent Nikro HVAC cleaning in Houston for homeowners who need evaporator coil, blower, condenser, air handler, and heat exchanger service without the runaround of a coupon-priced bait-and-switch. A typical Nikro system cleaning runs $340-$620 depending on which components need attention, and we deliver a written price before any panel comes off. We are not affiliated with or authorized by Nikro; we are an independent Nikro service provider with no obligation to sell you parts you do not need. If you own a Nikro air handler or package unit in the Energy Corridor, Memorial, or any Houston neighborhood where Gulf Coast humidity has been pushing through your system since 2015 or earlier, call (346) 251-8919 for a free estimate with a written number you can hold in your hand.
How Nikro Products Fail - and How We Fix Them
- Nikro SL4000 Series blowers - bearing wear from humidity cycling. The SL4000’s direct-drive blower motor sits low in the cabinet where Houston’s summer humidity pools. We regularly find bearing grease washed out by condensate splash-back in homes near Braeswood and the Medical Center. Our fix: pull the blower assembly, clean the housing with negative-pressure extraction (suction that contains debris instead of spreading it), and replace with OEM Nikro bearings or SKF equivalents that handle moisture better. The photo record shows the rust pattern before we quote the work.
- Nikro PAC series package units - coil fin corrosion from salt air. PAC units installed within fifteen miles of Galveston Bay show aluminum fin deterioration that standard coil cleaners accelerate. We’ve learned to use foaming agents at lower pressure, then rinse with deionized water. The alternative is fin replacement, which most Houston homeowners do not need if the corrosion is caught before the copper tubing is exposed.
- Nikro HV2000 air handlers - drain pan microfractures in heat mode. The HV2000’s polymer drain pan flexes more than metal alternatives, and Houston’s brief but sharp winter heating cycles stress the corners. Water finds the crack, runs into the insulation below, and breeds mold the homeowner smells before seeing. We pull the pan, document the crack with the borescope camera, and replace with an updated Nikro pan or a Plenum-rated stainless equivalent. Haven Standard Clause 1 applies: written price before the pan comes out.
- Nikro EC motor modules - control board communication errors after power events. Houston’s spring storm season and CenterPoint voltage fluctuations throw off the EC motor’s variable-speed logic. The module does not always fail outright; it drifts, causing uneven airflow that homeowners mistake for a dirty filter. We test communication voltage at the board, clean the module heatsinks (dust here causes thermal shutdowns in August), and recommend a surge protector if the home’s panel history shows repeated events. No module replacement unless the test fails.
- Nikro heat exchanger cells - scale buildup from hard water mist. In homes with whole-house humidifiers or poorly sealed return plenums (the main distribution box where air mixes before entering duct runs), mineral scale plates the heat exchanger surface. Efficiency drops before safety is compromised, but the efficiency loss shows up on the electric bill first. We descale with manufacturer-approved chemistry, never mechanical scraping that voids the remaining warranty, and photograph the cell condition before and after.
Our Nikro HVAC Cleaning Process

- 1
Call and schedule. A live person answers, checks our calendar, and books a window. No automated queue.
- 2
Arrival and system identification. The technician confirms the Nikro model and serial, checks the installation date, and runs the system through a heat and cool cycle to hear what the homeowner hears.
- 3
Borescope inspection and photo documentation. We feed the camera through every accessible port. The photo goes first. The pitch comes later, if it’s warranted. The homeowner sees the debris, the corrosion, or the crack on a tablet before any price is discussed.
- 4
Written scope and price. Haven Standard Clause 1: one flat price per system, agreed in writing, with line items for labor, parts (OEM Nikro or quality aftermarket, specified), and the 365-Day Done Right Promise. No per-vent pricing, no add-on surprise.
- 5
Cleaning and repair. We use Nikro-compatible tools - Rotobrush for duct runs, Nikro’s own negative-pressure equipment where specified, Abatement Technologies HEPA containment if microbial growth is present. Technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews.
- 6
Post-work test and photo record delivery. System runs again, pressures and temperatures logged, before-and-after photos compiled into the job record. The homeowner receives the photo set and the written warranty by email before the truck leaves.

AfterWhat Nikro HVAC Cleaning Costs in Houston
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Evaporator coil cleaning (Nikro) | $280-$420 | Accessibility (attic vs. closet), fin condition, whether the TXV valve needs protection |
| Blower assembly cleaning and balance | $240-$380 | EC motor vs. PSC motor, bearing replacement vs. cleaning only |
| Condenser coil cleaning (Nikro package unit) | $180-$320 | Proximity to salt air, fin corrosion level, refrigerant recovery required |
| Air handler full service (HV2000 series) | $420-$620 | Drain pan condition, filter rack seal integrity, duct connection leakage |
| Heat exchanger descale and inspection | $340-$480 | Scale thickness, cell removal required, gasket replacement |
These are whole-system prices, not per-vent teasers. The low end assumes straightforward access and maintenance-level cleaning. The high end covers corrosion, component replacement, or attic work in July. Every estimate is free, and every price is written before work starts. Call (346) 251-8919 for your exact number.
Why Houston Homeowners Call CleanRun Air Duct Cleaning Houston for Nikro Work

We have cleaned Nikro systems in Houston since 2013, and the pattern we have seen - especially in neighborhoods like the Energy Corridor where 2015-2020 builds are hitting their first major service cycle - is that humidity turns a maintenance visit into a repair visit faster than most owners expect. Tomas Reyes, who leads our operation, spent years in the northeast before relocating to Houston and has a working education in how Gulf Coast conditions degrade components that held up fine in drier climates.
Our difference is documentation, not declaration. The 365-Day Done Right Promise is written on every invoice, not buried in a website footer. Every technician is background-checked and uniformed under Haven Standard Clause 3. We also service Lennox, Trane, and Carrier systems, which matters when your home has mixed-brand equipment or when a previous installer used non-Nikro components in a retrofit. The photo record, the written price, and the published license number are how we answer the industry’s credibility problem. You do not have to trust our word. You hold the evidence.
FAQs
No, professional cleaning does not void your Nikro warranty, provided the work does not involve mechanical alteration of sealed components or use of unapproved chemicals on coils or heat exchangers. We follow Nikro’s published maintenance guidelines and document our methods in your job record so warranty claims later are supported, not undermined. If your system is still under warranty, we note the service date and procedures for your files. Call (346) 251-8919 if you need help locating your warranty terms.
For consumables like bearings, gaskets, and drain pans, quality aftermarket parts often outperform OEM at lower cost and with faster availability. For control modules and EC motors, we typically recommend OEM Nikro because aftermarket equivalents in those categories have higher failure rates in our Houston data. We specify which category your repair falls into in the written estimate, and we do not substitute without your approval. Bring a competitor’s quote; our Free Second Opinion puts our number next to it in writing.
Every CleanRun job includes a Documented Photo Record of every duct run and accessible component, delivered to you by email before the crew leaves. You see the debris at the first elbow, the scale on the heat exchanger, the clean surface after. This is standard, not an upgrade. If a company cannot show you what was inside your system, they are selling vacuum noise. Call (346) 251-8919 for an estimate that includes the photo record.
Fifteen years is not automatic retirement age for a Nikro air handler or package unit, but it is the threshold where cleaning cost should be weighed against remaining service life. We assess heat exchanger integrity, refrigerant pressure holding, and blower motor condition before recommending cleaning versus replacement. If the core components are sound, a thorough cleaning often restores efficiency for years. If the heat exchanger shows stress cracking or the coil has multiple leaks, we tell you so and stop the quote. No cleaning job is sold to delay an honest replacement conversation.
Every three to five years for the evaporator coil and blower in typical residential use, sooner if you have pets, run the fan continuously, or live within ten miles of the Ship Channel where particulate load is higher. Condenser coils exposed to cottonwood bloom or construction dust may need annual rinsing. We do not sell maintenance plans that clean more often than the system warrants; we schedule based on what the borescope shows. The first inspection is free, and it gives you a baseline. Call (346) 251-8919 to set it up.
