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.
Fast, Reliable HVAC Cleaning Across Gresham
HVAC cleaning in Gresham typically costs between $450 and $1,100 for a full system, depending on how many units you have and what we find inside. Most jobs here take 4 to 7 hours, and we schedule within a week of your call. Gresham’s damp, foothill air works its way into duct systems in ways Portland proper doesn’t see, so getting the coil, blower, and handler clean matters more here than you might expect. Call (806) 606-6902 and we’ll give you a written price before any work starts.
Why CleanRun Air Duct Cleaning Is a Fit for Gresham Homes
We’ve worked enough split-levels and ranch-style homes between Rockwood, Hollybrook, and Kelly Creek to know that Gresham duct jobs don’t look like Portland duct jobs. The housing stock is older, the crawl spaces run damper, and the flex duct sags more. Our HVAC Cleaning crews photograph every duct run before and after, so you see the standing water or compacted debris we find rather than taking our word for it. Founded in 2013, we’ve cleaned systems in more than 52,000 homes, and every one got the same thing: a written price before we touched a panel, and a photo record when we left. Tomas Reyes, who runs our operations, insists on that. No exceptions.
Scheduling a crew to Gresham is straightforward from our Portland dispatch office. When you call, a live person answers, takes your address, and gives you an arrival window. Our technicians are background-checked, uniformed, and identified by name before they show up. They’ll have the right equipment on the truck for Gresham-specific work: negative-pressure extraction units, HEPA filtration, and camera scopes for inspecting sagging flex runs in crawl spaces.
Our HVAC Cleaning Services in Gresham

Evaporator Coil Cleaning
The evaporator coil sits inside your air handler and cools the air before it moves through your supply ducts. In Gresham, that coil runs wet for big stretches of the year because of the elevated humidity coming off the Columbia Gorge. Wet coils collect dust fast, and that dust becomes a paste that insulates the coil and drops your system’s efficiency. A coil that’s gone 3 to 4 years without cleaning around Gresham often shows a measurable temperature difference before and after we work on it. We clean it with professional-grade equipment, not a brush and a spray bottle, and we photograph the coil before and after.

Blower Cleaning
Your blower fan pulls return air in and pushes conditioned air out. In Gresham homes with wood stoves, the blower wheel picks up fine particulate that bakes on over time. The fan gets louder, moves less air, and forces the system to run longer. We pull the blower assembly, clean the wheel and housing, and document the before-and-after with photos. If the blower is out of balance or the bearings are worn, we’ll tell you in writing and give you a price for replacement before doing anything.

Condenser Cleaning
The condenser is the outside unit, and in Gresham it fights a few specific enemies: cottonwood and alder pollen in spring, fir needles, and moisture-driven algae growth. A dirty condenser makes the whole system work harder and shortens the compressor’s life. We clean the coil fins, check the refrigerant lines for damage, and clear debris from the surrounding area. If you live east of Gresham on a gravel road, the condenser is going to need more frequent attention, and we’ll give you a realistic interval after we see it.

Air Handler Cleaning
The air handler is the cabinet that houses the blower, the evaporator coil, and often the filter. In Gresham’s 1970s and 1980s tract homes, air handlers frequently sit in crawl spaces where moisture and pest activity make them dirtier than a hallway closet install would be. We clean the interior surfaces, the drain pan, and the coil drain line. A clogged drain line in a damp crawl space will overflow, and that water ends up doing more than just making a mess. We inspect it as part of every air handler cleaning.

AfterTrusted Brands We Service in Gresham
If your system is a Honeywell, Rotobrush, Nikro, or Guardsman unit, our technicians know it. We carry common parts and filters for these brands on the truck, which means fewer return trips for Gresham homeowners. Guardsman and Honeywell make up a large share of the equipment we see in Gresham’s older housing stock, and we service both regularly. You don’t need a brand-specific contractor for a cleaning, and you’ll get a written price from us before we start regardless of what name is on the unit.
Common HVAC Cleaning Problems We See in Gresham Homes

- Sagged flex duct in crawl spaces. The original 1980s installs in Rockwood and other older Gresham neighborhoods often used flex duct without enough hangers. Decades of gravity and damp air create low bellies that collect standing water and compacted debris. A camera inspection finds these; a quick visual walkthrough from the register does not.
- Mold inside the duct liner. Gresham’s extra rainfall and the moisture trapped in crawl-space duct runs encourages microbial growth inside the flex duct, not on the surface where a simple brushing might reach. This requires source removal with negative pressure and HEPA filtration, plus coil treatment to keep it from returning.
- Wood stove particulate loading. Homes that burn wood through the winter put fine ash and creosote dust into the return air stream. That particulate coats the blower wheel and the evaporator coil faster than in homes without wood heat. The fix is more frequent cleaning, and we’ll give you a schedule that matches how much you burn.
- Unpaved road dust east of town. Properties off gravel roads around Orient, Powell Valley, and Springwater see dust loading that city homes in Portland never experience. Compacted pollen and road dust sticks to every interior surface of the duct system, and a rushed agitation step leaves it in place. We slow the job down and loosen that debris fully before extraction.
Pricing for HVAC Cleaning in Gresham, OR
A single-system HVAC cleaning in Gresham with full coil, blower, handler, and duct work runs between $450 and $700 for most homes. If you have two systems, a crawl-space air handler that needs extra access time, or outbuilding HVAC on the property, expect $700 to $1,100. The price is set in writing before we start, under Haven Standard Clause 1, and it does not change based on what we find once the panels come off. Quotes from national chains in the Portland metro often start at $79 or $99 per vent and climb once the technician is on site. Our number is one flat price per system, agreed before we touch anything. Call (806) 606-6902 and we’ll put a written estimate in your hands within a day or two.

FAQs - HVAC Cleaning in Gresham

Every 18 to 24 months, compared to every 3 to 4 years for a city lot in Portland. Unpaved road dust puts fine particulate into the return air at a much higher rate, and that dust compacts inside the duct walls over a single season. If you also burn wood, pull that interval closer to every 12 to 18 months. Call (806) 606-6902 and we’ll tell you what your system actually needs based on a camera inspection, not a blanket schedule.
Gresham sits against the Cascade foothills and receives several inches more rain annually than the westside suburbs, so the air in your crawl space holds more moisture. That moisture condenses inside flex duct low spots, and mold grows because the duct liner stays damp for weeks at a time. Beaverton gets less rain, the crawl spaces stay drier, and the problem stays dust-only. Our cleaning protocol addresses the moisture and the microbial growth, not just the visible dust.
Usually, yes. We pulled a flex duct in a Rockwood split-level last week where the original 1980s install had sagged into a low belly. Our camera inspection showed standing water and compacted debris in that sag, and after source removal with negative pressure and HEPA filtration, we re-supported the run and treated the evaporator coil to stop the microbial growth from returning. If the duct liner itself is badly deteriorated, we’ll tell you replacement makes more sense and give you a written price for that before doing anything.
Yes, and here’s why. Fine ash and creosote dust from a wood stove are small enough to bypass a standard return filter, so they coat the blower wheel, the evaporator coil, and the interior duct surfaces faster than in a home without wood heat. That coating reduces airflow and holds odor. If you burn regularly through Gresham’s long damp winters, plan on a full HVAC cleaning every 18 months instead of every three years. Call (806) 606-6902 for a written estimate.
Outbuilding systems run colder and wetter, especially in detached shops or studios that sit unheated for stretches. The ducts and coil see bigger temperature swings, which means more condensation inside the system. We treat outbuilding HVAC cleaning as a separate job from the main house, with its own camera inspection, its own written price, and its own photo record. If the outbuilding sits on a gravel drive or near open land, expect heavier particulate loading and a shorter interval between cleanings.
