A real person answers, schedules your slot, and confirms your upfront price before a single tool is lifted. Our technicians arrive in marked vehicles, uniformed and background-checked, carrying professional-grade Rotobrush and Nikro equipment. They know Raleigh Hills’s postwar housing stock - the original sheet-metal ductwork, the mastic joints, the flex-duct boots - because they’ve cleaned it, repaired it, and treated it dozens of times over.
We also stand behind our work with the 90-Day Done Right Promise. If something’s not right, we return at no charge. No paperwork, no arguing. That’s been our way for over 42 years.
Our HVAC Cleaning Services in Raleigh Hills
Evaporator Coil Cleaning
The evaporator coil in your Raleigh Hills home works hardest during our brief but intense summer dry spell, when systems that sat damp all winter suddenly face 90-degree days. Mold and biofilm that grew on the coil through the wet season bake hard in July and August, cutting efficiency and forcing your compressor to run longer. We access the coil, clean it with foaming agents and low-pressure rinse, and verify the result with camera inspection. For Raleigh Hills’s hillside homes with crawl-space air handlers, this service is critical - the coil often sits in the same damp environment that compromises the ductwork below.

Blower Cleaning
The blower wheel moves every cubic foot of air through your Raleigh Hills home, and in our market it collects a distinctive mix: fine silt from the Tualatin Mountain slopes, pollen from the dense canopy, and mold spores drawn up from damp crawl spaces. A dirty blower drops airflow, creates uneven temperatures between rooms, and strains the motor. We remove the blower assembly, clean the wheel and housing, and reassemble with balanced operation verified. Most Raleigh Hills jobs complete this in under two hours as part of a full system clean.

Condenser Cleaning
Your outdoor condenser coil faces a different challenge in Raleigh Hills. The same fog and ground moisture that keeps crawl spaces damp also coats the condenser fins with a fine film that traps pollen and debris. Add the cottonwood fluff that drifts through the Beaverton-Hillsdale corridor in late spring, and you have a unit working harder than it should. We clean the coils, straighten damaged fins, and verify refrigerant pressures. This is often the quickest portion of a full HVAC cleaning, but the performance difference is immediate.

Air Handler Cleaning
In Raleigh Hills’s split-level and ranch homes, the air handler frequently lives in an unconditioned crawl space or partial basement - exactly where Washington County’s wet-season moisture concentrates. We clean the entire air handler cabinet, including the drain pan, which in these homes often shows standing water or slow drainage from biofilm buildup. A clean air handler prevents the musty restart smell that hits so many Raleigh Hills systems in October, when the first cold snap forces the heat on after months of dormancy. Our HVAC Cleaning team treats the cabinet interior with antimicrobial where indicated, documented before and after with camera footage.

Heat Exchanger Cleaning
Furnace heat exchangers in Raleigh Hills’s older homes require careful inspection. Decades of cycling through wet winters and dry summers can stress metal, and debris accumulation affects combustion efficiency. We visually inspect and clean the exchanger surfaces, checking for any signs of deterioration that would warrant a separate repair conversation. This step is non-negotiable for safe, efficient operation.

Coil Treatment
After cleaning, we offer coil treatment with EPA-registered antimicrobial products from Abatement Technologies. In Raleigh Hills’s climate, this step pays for itself. The treatment creates a residual barrier against mold recurrence on the evaporator coil and in the drain pan, where damp conditions persist longest. We recommend it for any home with a history of musty odors or visible mold, which in our experience describes a significant share of the 97225 housing stock.

Common HVAC Cleaning Problems We See in Raleigh Hills Homes
- Original mastic joints dried out and separated. The sheet-metal ductwork in 1950s-1970s Raleigh Hills homes was sealed with mastic that degrades after decades of moisture cycling in unconditioned crawl spaces. Once joints open, they pull in crawl-space air, debris, and mold spores - contaminating the entire supply stream.
- Early flex-duct connections loosened at boots. The flex-duct boots installed in postwar split-levels weren’t built for sixty years of vibration and humidity. They pull apart, sag, and tear, especially at the cold-side connections. Our crew finds this on SW Dosch Road and similar streets every wet season.
- Damp insulation wrap harbors recurring mold. Even after duct cleaning, untreated insulation wrap recontaminates the system within weeks. The vapor barriers in these older crawl spaces are often absent or deteriorated, so moisture keeps coming.
- Seasonal baking hardens debris onto coils. Raleigh Hills’s sharp wet-dry contrast means mold and dust that grew all winter bake onto the evaporator coil in summer, forming a hard layer that standard filter changes won’t touch.

FAQs - HVAC Cleaning in Raleigh Hills
Your crawl-space ductwork sits in months of ground moisture from October through May, and the original vapor barrier - if there ever was one - has likely deteriorated. Washington County’s wet season drives humidity directly into unconditioned crawl spaces, and the flex-duct boot connections are the first place mold colonies establish. On a split-level home near SW Dosch Road, our crew found the original flex-duct boot connections in the cold-side crawl space coated with black mold by late February. We cleaned the duct runs, treated the boots with antimicrobial, and recommended a vapor barrier install to stop recurrence. Call (844) 685-6342 if you’re seeing this pattern - we can assess whether cleaning alone will solve it or if moisture control is needed.
Yes, if the smell originates in the ductwork or air handler - which it typically does in sloped-lot ranches with crawl-space systems. The musty restart odor in October comes from mold and biofilm that grew during the damp months, then baked and concentrated over summer. We clean the source, treat with antimicrobial where indicated, and document with camera inspection. If the smell persists after cleaning, that signals a moisture intrusion problem beyond the HVAC system itself. Most Raleigh Hills ranch jobs we handle resolve the odor in one visit. Call for a free estimate.
Not when done properly, though we always inspect them first. The early flex-duct connections in Raleigh Hills’s postwar homes have often loosened or sagged from decades of vibration and humidity. Our technicians secure them with insulated supports before cleaning, and we flag any that need replacement rather than risk a tear. If your boots are too deteriorated to safely clean, we’ll show you the camera footage and quote repair before proceeding. No surprises on the bill.
Every three to five years for maintenance, or sooner if you notice musty odors, visible mold, or reduced airflow. Raleigh Hills’s extended damp season and sharp summer dry spell create a more aggressive cycle of mold growth and debris baking than flatter, newer areas experience. Homes with no vapor barrier or original mastic joints may need more frequent attention. We recommend coil treatment with each full cleaning to extend the interval. Call (844) 685-6342 and we’ll assess your specific system.
Yes - coil treatment is available as an add-on to any HVAC cleaning service. We apply an EPA-registered antimicrobial from Abatement Technologies to the evaporator coil and drain pan, creating a residual barrier against mold recurrence. In Raleigh Hills’s climate, we strongly recommend it. The treatment adds $85-$140 to the job and is documented in your before-and-after camera record. Ask about it when you call for your estimate.
