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 Hillsboro
HVAC cleaning in Hillsboro typically costs $290-$520 for a full-system cleaning of a standard 2,000-square-foot home, and most jobs take three to five hours. We schedule Hillsboro appointments Monday through Saturday, with crews arriving from the Portland dispatch office, already stocked with the Rotobrush and Nikro equipment your system needs. If you’re watching your return-air grille fill with grass pollen every May, call (806) 606-6902 and we’ll give you a written price before a single panel comes off.
We know Hillsboro’s ductwork. Not the generic kind of knowing that comes from a training video, but the kind that comes from pulling collapsed flex duct from a Tanasbourne crawlspace and photographing what was actually inside. That’s what this page is about.
Why CleanRun Air Duct Cleaning Is Hillsboro’s Preferred HVAC Cleaning Company
CleanRun has served 52,000+ homes since 2013, every one with a written price before work started and a documented photo record when the crew left. In Hillsboro, that record matters more than most places, because what’s inside your ducts is often invisible until we put a camera in there: fine grass pollen powder, drywall dust from phased construction, and the gray-brown mat of agricultural particulates that settles into return-air plenums all winter.
Our Hillsboro customers see the before photo before we say a word about what needs to happen next. That’s been the practice since Tomas Reyes founded the company, and it hasn’t changed. The HVAC Cleaning team works under the H.A.V.E.N. Standard, which means Clause 1 applies on every job: a written price, delivered before work begins, with no exceptions and no “call for a quote” runaround.
For Hillsboro specifically, we stock the replacement flex duct, filter media, and coil cleaning chemicals sized for the subdivision homes and ranch layouts that dominate the area. When a blower needs to come out of an air handler in AmberGlen, we don’t have to drive back to the warehouse. We carry it.
Our HVAC Cleaning Services in Hillsboro
Evaporator Coil Cleaning
Your evaporator coil sits inside the air handler where it pulls heat from the air. In Hillsboro, after the May-June grass seed pollination window, that coil can carry a sticky film of pollen and dust that cuts heat transfer by a measurable margin. A coil loaded with valley dust forces the system to run longer to hit the same thermostat setting. We clean it with a two-stage process: first a dry brush and HEPA vacuum pass to lift loose debris, then a foaming coil-specific cleaner that breaks down the organic layer without corroding the aluminum fins. Expect $150-$280 for evaporator coil cleaning as a standalone service in Hillsboro, or $90-$160 when bundled with a full duct cleaning.
Blower Cleaning
The blower wheel is the fan that pushes conditioned air through your supply runs. In Hillsboro ranch homes near unpaved roads, blower blades accumulate a fine layer of dust that reduces airflow before your filter looks dirty. A dirty blower runs out of balance, wears motor bearings faster, and pulls more electricity. We remove the blower assembly, photograph it on the bench, clean each blade with compressed air and a soft-bristle detail brush, and reinstall with new gaskets if the old ones have compressed. Blower cleaning in Hillsboro runs $120-$220, and it’s often the single highest-impact service for homes reporting weak airflow from rooms at the end of a long duct run.
Condenser Cleaning
The condenser is the outdoor unit, and in Hillsboro’s wet season it lives through months of rain, leaf litter, and occasional valley-floor inversions that trap particulates near ground level. A clogged condenser coil raises refrigerant pressure and shortens compressor life. We clean condenser coils with a low-pressure rinse and a fin-safe coil comb, never a pressure washer that folds the aluminum fins flat. Hillsboro condenser cleaning runs $110-$190, and we recommend it annually if your unit sits near cottonwood or maple trees or faces an open grass field.
Air Handler Cleaning
The air handler is the indoor cabinet holding the blower, the evaporator coil, and the filter housing. In Hillsboro’s damp crawlspace installs, the air handler cabinet itself can develop mold on the interior surfaces where condensation collects. We remove the access panels, photograph the interior, then clean all cabinet surfaces with an Abatement Technologies HEPA-filtered extraction unit and a mold-inhibiting, EPA-registered sanitizer applied to the drain pan and coil frame. Expect $180-$320 for full air handler cleaning in Hillsboro, depending on access and cabinet size.

BeforeAfterTrusted Brands We Service in Hillsboro
We work on every major HVAC brand found in Hillsboro homes: Carrier, Trane, Lennox, Rheem, Goodman, York, and Bryant. What we bring to the job is a professional-grade equipment roster you can look up yourself: Rotobrush for negative-pressure duct extraction, Nikro for HEPA-filtered detail work, and Abatement Technologies for containment and air scrubbing. If you’ve been quoted by a crew working off a shop vac and a drill brush, the difference will be obvious in the photo record we hand you at the end of the job. We also service Aprilaire and Honeywell filtration systems and can replace filters or media during the same visit.
Common HVAC Cleaning Problems We See in Hillsboro Homes
- Collapsed flex duct in pre-2005 subdivisions. In Tanasbourne and AmberGlen, flexible ductwork from the late 1980s through early 2000s builder boom is now 20-30 years old. In Hillsboro’s damp crawlspaces, that flex can kink or partially collapse, starving rooms of airflow while the blower runs longer. We find this with a camera, then repair or replace the damaged run.
- Grass pollen loading in return-air ducts. Hillsboro sits in the middle of North America’s densest cool-season grass seed production belt. During May and June, ambient pollen levels here exceed Portland and Beaverton by a wide margin, and that pollen gets pulled into return-air grilles at the base of hallways and stairs. It settles in the return plenum and filter housing, then blows through the supply side once the filter reaches capacity.
- Drywall dust in Orenco Station package units. The new-urbanist development around Hillsboro’s MAX station was built in phases starting in the late 1990s, and many rooftop package units share chases that were never cleaned after original construction punch-out. Fine drywall dust from those phased builds sits in the supply runs and on the blower wheel, and a standard filter change never touches it.
- Mold in crawlspace-mounted air handlers. Hillsboro’s prolonged wet season, October through May, keeps crawlspace humidity high for months at a stretch. The inside of an air handler cabinet in that environment is a condensation magnet. We regularly photograph dark mold colonies on blower housings and drain pans in Hillsboro ranch homes, then remove them with HEPA extraction and sanitizing, not a fog-and-go treatment.

FAQs - HVAC Cleaning in Hillsboro
Annual cleaning is the realistic interval if your home sits south of Highway 26 or west toward the open Tualatin Valley, where the grass seed pollen load during May and June is the heaviest in North America. We recommend a full HVAC cleaning every 12 months in that zone, with a filter change every 30-60 days during the pollination window. Homes in denser, tree-shaded parts of Hillsboro can often go 18-24 months between cleanings, but the return plenum tells the real story when we put a camera in it. Call (806) 606-6902 and we’ll schedule a look at what’s actually in your ducts.
Flex duct from the late 1980s through early 2000s Tanasbourne builds is now 20-30 years old, and it does not clean the same way rigid metal duct does. If a flex run has kinked or partially collapsed in the crawlspace, a standard negative-pressure cleaning will pull air through the path of least resistance and leave the damaged section untouched. That’s why we camera-inspect the supply runs before and after cleaning in Tanasbourne specifically. If we find a collapsed run, we show you the photo, quote the repair in writing, and complete it during the same visit. Our crews have pulled collapsed flex from Tanasbourne crawlspaces that looked fine from the register side but were starved to half their rated airflow.
Source removal means we physically extract the debris, pollen, dust, and mold from inside the duct system using negative-pressure extraction and HEPA-filtered tools, rather than fogging the system with a sanitizer and hoping for the best. In Hillsboro, this matters because the particulate load in your ducts is real material: grass pollen, valley dust, drywall powder, and the gray agricultural film that settles out of winter inversions. Fogging does not remove that material, it just treats the surface it’s sitting on. Our method uses Rotobrush and Nikro extraction equipment to pull the debris out at the source, then we photograph the inside of every duct run before and after so you can see what was removed. Fogging alone cannot produce a before-and-after photo record that shows a clean duct.
Because a coil loaded with Hillsboro’s May-June grass pollen does not stop cooling all at once, it degrades gradually. What you notice is the system running longer to hit the same target, higher summer electric bills, and eventually a frozen coil or a failed compressor. After the pollen season, the sticky organic layer on the coil attracts more dust, which insulates the coil surface and reduces heat transfer. A coil cleaning after the pollen window is the single best thing you can do for cooling efficiency in Hillsboro. We charge $150-$280 for coil cleaning as a standalone service, and we photograph the coil before and after so you can see the difference.
Yes. Homes in the historic downtown core, many of them pre-WWII Craftsman and bungalow stock, often have retrofitted forced-air systems routed through original narrow wall cavities that were never designed for ductwork. Access points are tight, runs are short and sharp-angled, and some systems use a mix of rigid metal and flex in cramped floor joists. Cleaning these systems takes longer and costs more than a standard ranch home, but the same written-price rule applies: we quote the full number before we start, and we photograph every run we can physically reach. If a run is inaccessible, we tell you that before the job begins, not after.
