Air Duct Cleaning in Hillsboro - One Flat Price, Before-and-After Photos

Air Duct Cleaning in Hillsboro, OR

Most Hillsboro homes need their dryer vents cleaned every 12 to 18 months, and the reason is specific to this city: the Tualatin Valley’s grass seed pollen season runs hard from May through June, and that fine particulate works its way into every vented system in the house. Add in the damp crawlspaces under the Intel-era ranch homes in Tanasbourne and AmberGlen, and you get dryer vents that clog faster here than almost anywhere else in the metro. If your dryer has been taking longer to finish a load, call (806) 606-6902 and we’ll put a written price in front of you before any work starts.

Why Hillsboro Homes Are Different

Hillsboro sits at the core of Oregon’s grass seed farming belt. The Tualatin Valley immediately surrounding the city produces more cool-season grass seed than anywhere else in North America, and during the May-June pollination window, ambient grass pollen concentrations here far exceed those in neighboring Portland or Beaverton. That pollen loads return-air ducts and filter housings at a rate that makes annual duct cleaning a genuine indoor air-quality necessity for Hillsboro households, not an optional upgrade. We see it on the camera before every cleaning: a fine, pale-yellow film coating the first few feet of return ducting in homes from Orenco to the historic downtown core.

The housing stock compounds the problem. The late 1980s through early 2000s Intel-driven boom built out vast tracts in Tanasbourne, AmberGlen, and the Orenco corridor using flexible ductwork that is now 20 to 30 years old and prone to kinking, partial collapse, and heavy debris accumulation in Hillsboro’s damp crawlspaces. A smaller inventory of pre-WWII Craftsman and bungalow homes near downtown have retrofitted forced-air systems routed through original, narrow wall cavities that present real access challenges. And the city’s prolonged wet season, October through May, keeps crawlspace humidity elevated for months at a stretch, promoting mold colonization in the flex-duct supply runs that serve the valley’s predominant ranch and split-level floor plans.

There is also the inversion effect. The Tualatin Valley’s geography creates thermal inversions in winter that trap agricultural dust and wood-smoke particulates near ground level, raising the particulate load drawn into residential HVAC systems. All of this means one thing for our crews: the standard Hillsboro duct cleaning involves more than a quick vacuum pass. It means inspection, documentation, and repair work that addresses what the valley’s climate and building stock actually do to ductwork.

Our Main Hillsboro Services

The two services Hillsboro homeowners call about most are full air duct cleaning and complete HVAC system cleaning. Here is what each involves in this city.

Air Duct Cleaning in Hillsboro

Hillsboro’s 20-to-30-year-old flex ducting in neighborhoods like Orenco and Tanasbourne collects grass pollen, dust, and pet dander at a rate that surprises most homeowners the first time we show them the before photos. Our process uses negative-pressure extraction with a Rotobrush agitation system, which means the debris is loosened and pulled out under vacuum rather than blown around the house. Every duct run is photographed before and after, and you receive that photo record as part of your job file. Learn more about Air Duct Cleaning in Hillsboro and what the full service includes.

HVAC Cleaning in Hillsboro

HVAC cleaning in Hillsboro often turns into a bigger job than the homeowner expected, because the blower wheel and evaporator coil in these Intel-era systems have rarely been touched since installation. The damp crawlspaces mean coil corrosion and biological growth are more common here than in drier parts of the metro. We clean the entire system, from the return to the supply registers, and document everything with the same photo record standard. Read more about HVAC Cleaning in Hillsboro and what it covers.

Dryer Vent Cleaning in Hillsboro

Dryer vent cleaning in Hillsboro is a house fire risk and a utility bill issue more than a convenience service. The grass seed pollen that blankets the valley in May and June gets drawn into dryer vents through exterior termination points, where it mixes with the lint that already builds up in these systems. Homes built in the 1990s and early 2000s often have long, bending vent runs through crawlspaces that never saw adequate maintenance, and we regularly pull out 3 to 5 pounds of packed lint and pollen mat from a single Orenco or Tanasbourne vent. Our complete Dryer Vent Cleaning service includes before-and-after photography of the entire run, delivered as part of your written job record.

Dryer Vent Inspection

Signs you need it

Your dryer takes more than one full cycle to dry a normal load, the exterior vent flap doesn’t open fully when the dryer runs, or you notice a burning smell in the laundry room.

What it costs in Hillsboro

A dryer vent inspection in Hillsboro runs $80 to $150 when scheduled as a standalone visit, and we photograph the entire run from the dryer to the exterior termination point.

How we do it

We run a camera through the full vent length, photograph every obstruction and bend, measure the static pressure with a manometer, and hand you a written summary before recommending any cleaning or repair.

Vent Cleaning

Signs you need it

It has been more than a year since the last cleaning, the vent flap sticks or stays closed, or the laundry area feels noticeably humid when the dryer runs.

What it costs in Hillsboro

Full dryer vent cleaning in Hillsboro runs $130 to $260 depending on vent length and access; homes with roof terminations or crawlspace runs on the longer end fall at the higher end of that range.

How we do it

We run a rotating brush and negative-pressure vacuum from the dryer connection to the exterior vent, alternating direction as needed, then photograph the clean bore from end to end.

Lint Removal

Signs you need it

You see visible lint around the dryer base or exterior vent opening, or the dryer is overheating and shutting down mid-cycle.

What it costs in Hillsboro

Lint removal as part of a full vent cleaning is included in the $130 to $260 range; as a targeted service for a partially clogged run, it runs $110 to $200.

How we do it

We disassemble the vent connection at the dryer, run a flexible auger brush through the entire run to break up the packed lint, vacuum out the debris, and document the before and after states.

Vent Rerouting

Signs you need it

Your vent run is made of plastic or foil accordion tubing, the run exceeds 25 feet, or it has more than two 90-degree elbows that trap lint.

What it costs in Hillsboro

Vent rerouting in Hillsboro runs $250 to $550 depending on the run length and the wall or crawlspace access required, with the written price agreed before we cut any drywall.

How we do it

We replace the old run with rigid metal duct, minimize bends, relocate the termination point if needed, and seal every seam before photographing the finished work.

Bird Guard Installation

Signs you need it

You hear birds near your vent termination, see nesting material poking out of the exterior flap, or find dead insects or droppings near the laundry area.

What it costs in Hillsboro

Bird guard installation in Hillsboro runs $60 to $140 when done as part of a vent cleaning visit, and slightly more when scheduled as a standalone call.

How we do it

We install a galvanized steel cage over the exterior termination point, verify the flap still opens freely, and photograph the installed guard from the outside.

What Dryer Vent Cleaning Costs in Hillsboro

How often should a Hillsboro dryer vent be cleaned?

Every 12 to 18 months. Hillsboro’s grass pollen season and damp crawlspaces clog vents faster than in most of the metro, so annual service is the standard we recommend for homes in Tanasbourne, AmberGlen, and Orenco. Call (806) 606-6902 for a written price.

Can a clogged dryer vent actually cause a house fire?

Yes. Lint is combustible, and when airflow is restricted, the dryer’s heating element runs hotter and longer. The U.S. Fire Administration reports thousands of dryer fires annually, and most involve clogged vents. A written price and a photo record are part of every cleaning.

Duct Repair & Sealing in Hillsboro

Duct repair and sealing in Hillsboro is usually a discovery job. We arrive for a cleaning, run the camera, and find a kinked flex run under the crawlspace or a disconnected return that has been pulling crawlspace air into the house since the day the system was installed. The 20-to-30-year-old flex ducting common across Tanasbourne, AmberGlen, and the Orenco corridor is at the age where seams fail, hangers break, and the inner liner separates from the insulation. Our Duct Repair & Sealing service covers everything from a single taped seam to full trunk line replacement, all documented with before and after photos.

Flex Duct Repair

Signs you need it

Rooms run noticeably hotter or colder than the rest of the house, you hear whistling from a supply register, or you see condensation on ductwork in a crawlspace.

What it costs in Hillsboro

Flex duct repair in Hillsboro runs $180 to $480 per damaged section, including replacing collapsed or kinked runs and reconnecting loose fittings.

How we do it

We cut out the damaged section, install a new length of R-6 or R-8 flex duct, secure both ends with mastic and aluminum tape, and photograph the finished splice.

Duct Sealing

Signs you need it

Your energy bills stay high even after scheduled filter changes, dust accumulates unusually fast on furniture, or the system runs constantly to hold temperature.

What it costs in Hillsboro

Whole-system duct sealing in Hillsboro runs $450 to $1,200 depending on the number of runs and accessibility of the crawlspace or attic.

How we do it

We seal every accessible seam and connection with a brush-on mastic compound, not tape, then perform a pressure test to quantify the leakage reduction in CFM.

What Duct Repair & Sealing Costs in Hillsboro

How do I know if my ducts actually need sealing?

If certain rooms never reach the thermostat temperature, dust appears on surfaces within days of cleaning, or the HVAC system runs for long stretches, duct leakage is likely. We verify with a camera inspection and a written pressure test result before recommending sealing.

Is duct sealing worth the cost?

In Hillsboro, yes. Leaky ducts pull crawlspace air into the house, which means mold spores, humidity, and whatever sits in the crawlspace enters your living space. Sealing reduces that intrusion and usually shortens HVAC runtime visibly within the first month. Call (806) 606-6902 for a written quote.

Air Quality & Sanitizing in Hillsboro

Air quality and sanitizing work in Hillsboro is driven by two local realities: months of crawlspace humidity that enables mold growth inside flex ducting, and the winter inversions that trap agricultural dust and wood smoke at breathing level. Homeowners in Orenco Station, a dense new-urbanist development built around the MAX station starting in the late 1990s, often run into shared HVAC chases and rooftop package units that were never cleaned after original construction punch-out, plus fine drywall dust from the phased builds. Our Air Quality & Sanitizing service includes a written Indoor Air Quality assessment, the sanitizing application itself, and the same before-and-after photo record we deliver on every job.

Mold Treatment

Signs you need it

You smell a persistent musty odor from supply registers, see dark staining on register faces or inside ducts, or allergy symptoms spike whenever the HVAC runs.

What it costs in Hillsboro

Mold treatment for duct interiors in Hillsboro runs $400 to $900 for a full system, with the written price fixed before any treatment begins.

How we do it

We apply an EPA-registered antimicrobial treatment using a fogging system that coats the full interior surface of the duct run, then photograph the treated surfaces before the system goes back into service.

Odor Removal

Signs you need it

A stale or unidentifiable odor returns every time the blower starts, or the house smells like crawlspace or old carpet when the heat kicks on.

What it costs in Hillsboro

Whole-house odor removal in Hillsboro runs $300 to $650 and includes one full treatment pass on every supply and return run.

How we do it

We identify the odor source with a camera walkthrough of the ductwork, clean any contaminated surfaces with a HEPA-filtered extraction system, then apply a neutralizing agent and photograph the result.

What Air Quality & Sanitizing Costs in Hillsboro

Does sanitizing actually do anything for dust mites or pet dander?

Sanitizing reduces biological contaminants like mold, bacteria, and odor-causing organisms on duct surfaces. Allergens like dust mites and pet dander are particles and need physical removal via HEPA-filtered cleaning, which is why we recommend cleaning before sanitizing in most Hillsboro homes.

Do I need a mold test before treatment?

Not necessarily. If we see growth on the camera, we show it to you in the photo record and recommend treatment directly. If you want a third-party lab confirmation, we can point you to a local certified hygienist, but our written assessment is enough to proceed in most cases.
