Our HVAC Cleaning Services in Aloha
Evaporator Coil Cleaning
The evaporator coil in your Aloha home works harder than it should. Valley fog keeps indoor humidity elevated for months, and that moisture coats the coil in a biofilm that reduces airflow and breeds mold. A typical evaporator coil cleaning in Aloha runs $180-$320. We access the coil, remove the buildup, and verify the results with our camera. Most Aloha homeowners notice stronger airflow and less musty odor within a day.
Coil Treatment
After cleaning, we apply an EPA-registered antimicrobial treatment to the coil and surrounding surfaces. In Aloha’s damp climate, this step matters. The Tualatin Valley’s persistent winter humidity means mold spores resettle quickly on untreated surfaces. Our coil treatment creates a hostile environment for regrowth without damaging the aluminum fins. This add-on typically runs $85-$145 when bundled with a full cleaning. For homes with a history of mold, we also install UV-C air purifiers in the air handler.
Air Handler Cleaning
The air handler is the heart of your forced-air system, and in Aloha’s 1970s tract homes, it’s often been neglected for 40-plus years. We disassemble and clean the blower assembly, housing, and return plenum. A full air handler cleaning in Aloha typically costs $240-$420 depending on access and contamination level. We check the drain pan for standing water, a common issue in valley homes where humidity overwhelms the condensate line.
Blower Cleaning
The blower wheel moves every cubic foot of air through your Aloha home. When dust and pollen from western Washington County’s grass seed fields cake onto the blades, efficiency drops and noise increases. Blower cleaning alone runs $150-$260 in Aloha. We remove the assembly, clean it off-site with compressed air and soft brushes, and balance it before reinstalling.
Condenser Cleaning
Your outdoor condenser faces a different enemy: the fine pollen and dust that blow across the Tualatin Valley each spring. We clean the coils, straighten fins, and verify refrigerant levels. Condenser cleaning in Aloha typically runs $120-$200. We recommend this service in late March, before the heavy grass-seed pollen arrives.
Heat Exchanger Cleaning
For Aloha homes with gas furnaces, the heat exchanger demands careful inspection. We camera-inspect for cracks and clean the surfaces to improve combustion efficiency. This service runs $200-$350 and includes a written condition report. Given the age of many Aloha heating systems, we flag any safety concerns immediately.

Common HVAC Cleaning Problems We See in Aloha Homes
- Original fiberglass-lined ductwork traps moisture and grows mold in Aloha’s foggy winters. The 1970s-80s tract housing that defines Aloha was built with fiberglass-lined sheet-metal ducts to minimal standards. That fiberglass acts like a sponge. By February, we regularly find black mold colonies an inch thick on the interior lining.
- Return-air intakes pull heavy grass-seed pollen from surrounding farmland into uncleaned ducts each spring. Western Washington County produces a significant share of the nation’s grass seed. When the wind blows from the west in May and June, that pollen loads directly into Aloha return vents. We’ve pulled handfuls of compacted pollen from filters that haven’t been changed in two years.
- Duct runs through unheated crawl spaces on split-level homes stay cold and damp, becoming permanent mold zones. This is the worst scenario we encounter in 97003. The downhill side of split-level ranches, especially east of 198th Avenue near the Beaverton boundary, has ductwork that passes through crawl spaces at 45 degrees and 90% humidity all winter. Nothing dries out. Nothing improves without professional intervention.
- Multiple owners and deferred maintenance mean many Aloha duct systems haven’t been touched since installation. Because Aloha has historically been an affordable entry point into the Portland metro, these homes have cycled through owners and rentals. We’ve met longtime residents who didn’t know their ducts could be cleaned.

FAQs - HVAC Cleaning in Aloha
The downhill-side duct runs in split-level ranches pass through unheated crawl spaces that stay at ground temperature all winter, which is why Air Duct Cleaning in Aloha is so important. In Aloha, that means 45-degree, fog-saturated air surrounding warm supply ducts. Condensation forms continuously. The fiberglass lining soaks it up. Mold follows. We see the thickest colonies in homes east of 198th Avenue near the Beaverton boundary, where the slope is steepest and the crawl spaces are deepest. Call (844) 685-6342 if you smell musty air from your vents - we’ll camera-inspect and show you exactly what’s growing.
Every 3-5 years for most Aloha homes, and every 2-3 years if you have the original fiberglass-lined ductwork or anyone with allergies or asthma in the household. The Tualatin Valley’s prolonged winter humidity means mold establishes faster here than in drier parts of Oregon. We cleaned a split-level ranch off 198th Avenue near the Beaverton boundary where the downhill crawl-space duct run had black mold colonies three inches thick. Using our Rotobrush system with EPA-registered antimicrobial coil treatment, we cleared the biofilm and installed a UV-C air purifier to prevent regrowth. That homeowner now schedules every two years. Call (844) 685-6342 to set your interval.
Yes, and it’s critical that you do before the lining degrades further. Our Rotobrush system agitates the fiberglass surface without tearing it, while our Nikro HEPA vacuum captures dislodged debris at the source. We then apply antimicrobial treatment to slow regrowth. In Aloha’s 1970s-80s housing stock, we’ve restored ductwork that homeowners assumed needed full replacement. Camera verification proves the result. Call (844) 685-6342 for an inspection - estimates are free.
No. Spring warmth does not dry out ductwork that’s embedded in a damp crawl space or coated in active mold. What spring does bring is the grass-seed pollen load from western Washington County farmland, which enters through return-air intakes and lands on the existing mold colonies, creating a combined allergen reservoir. The only solution is professional cleaning and, in many Aloha homes, a UV-C purifier to suppress regrowth. Call (844) 685-6342 before pollen season peaks.
Yes. We apply an EPA-registered antimicrobial coil treatment after every evaporator coil cleaning, and we strongly recommend it for Aloha homes given the valley’s humidity profile. The treatment costs $85-$145 when bundled with cleaning, and it creates a surface environment that resists mold resettlement. For chronic cases, we install UV-C lamps in the air handler. Both are standard offerings from our HVAC Cleaning team. Call (844) 685-6342 to discuss which option fits your system.
