Fast, Reliable HVAC Cleaning Across Alderwood Manor
HVAC cleaning in Alderwood Manor typically runs $280-$650 for a full system service, and most appointments are completed in a single visit. We answer calls live 24 hours a day, and our technicians usually reach homes in the 98036 area within the same day or next morning.
We’ve been driving to Alderwood Manor since 2012, back when much of this area was still recognizable from its farming days. The ranches and split-levels built between 1960 and 1985 still dominate the neighborhood, and we’ve learned their systems house by house. Our HVAC Cleaning team knows the original sheet-metal ducts, the sagging flex runs, and the crawlspace return intakes that pull in alder leaf debris year after year. If you’re off 196th St SW, near the old Alderwood Manor plat, or anywhere in 98036, we’ll be there when we say. Call (833) 700-5198 for a free estimate.
Why Bellows Air Duct & Vent Co. of Seattle Is Alderwood Manor’s Preferred HVAC Cleaning Company
Forty-two years in this region means we’ve watched Alderwood Manor change from berry fields to the suburban streets we drive today. Colin Merritt and our team have cleaned ductwork in homes where the original 1970s air handler was still running, and we’ve replaced systems that finally gave out after decades of damp winters.
Our reputation here is built on one thing: we don’t need to be called back. The 90-Day Done Right Promise is stamped on every job. If something isn’t right, we return at no charge. No paperwork, no arguing. Camera inspection before and after every clean gives you a visual record, not just our word. Our technicians are background-checked, uniformed, and they answer to a live person at our office 24 hours a day. That’s the square deal we’ve offered since 2012.
Our HVAC Cleaning Services in Alderwood Manor
Evaporator Coil Cleaning
The evaporator coil in your Alderwood Manor home works harder than it should. Our marine climate keeps humidity high from October through April, and that moisture coats the coil in biofilm that insulates it from proper heat exchange. A dirty coil in this environment can drop your system’s efficiency by 30% or more. We access the coil, clean it with professional-grade solutions, and verify the results with our camera. For homes near the wooded lots off 196th St SW, where shade keeps everything damp longer, this service is often the difference between a system that runs all day and one that cycles normally.
Blower Cleaning
Your blower wheel moves every cubic foot of air your home breathes. In Alderwood Manor’s older homes, we’ve found blower wheels caked with a gray-green biofilm that homeowners never see until we show them the camera footage. On a ranch off 196th St SW, we found a 1970s Rheem air handler with a biofilm-thick blower wheel and a return plenum matted with decomposed alder leaves. We cleaned the evaporator coil with Rotobrush and applied an Aprilaire coil treatment, restoring airflow after years of mold-driven allergies. Blower cleaning typically costs $180-$320 in Alderwood Manor, and it’s included in our full system service.
Condenser Cleaning
Your outdoor condenser faces Alderwood Manor’s wet winters and the pollen load from all that alder, cedar, and fir. We clean the coils, straighten fins, and clear debris from the cabinet so your system can reject heat properly. A condenser choked with cottonwood fuzz or leaf litter works harder, draws more power, and fails sooner. This is straightforward maintenance that pays for itself in efficiency and longevity.
Air Handler Cleaning
The air handler is where your system’s lungs and heart meet. In Alderwood Manor’s 1960s-1980s homes, these units often sit in damp crawlspaces or utility closets with poor ventilation. We clean the cabinet, the drain pan, and all accessible components, then treat with antimicrobial solutions where appropriate. Most air handler cleans in Alderwood Manor run $240-$420 depending on accessibility and condition.
Coil Treatment
After cleaning, we apply a protective coil treatment that inhibits biological regrowth. In Alderwood Manor’s climate, this isn’t optional. The Aprilaire treatment we use creates a barrier against the mold and mildew that thrive in our sustained humidity. It’s part of our full system service, and it’s especially valuable for homes with the original or single-replacement HVAC systems common in 98036.

Common HVAC Cleaning Problems We See in Alderwood Manor Homes
- Compressed organic mats in return ducts. Leaf debris pulled into crawlspace return-air intakes compresses into organic mats that hold moisture and feed mold colonies. This is the defining pattern in Alderwood Manor, tied directly to the neighborhood’s namesake tree canopy and the low-crawl construction of its build era.
- Pinhole corrosion in galvanized sheet-metal ducts. Original galvanized sheet-metal ducts corrode faster from damp marine air, creating pinhole leaks that worsen mold growth. The moisture doesn’t just stay in the air. It finds every seam and joint in aging metal.
- Sagging flex-duct trapping condensation. Flex-duct sag from age and humidity traps debris and condensation, reducing airflow and accelerating microbial buildup. We’ve found flex runs in Alderwood Manor crawlspaces holding standing water where the sag created a low point.
- Biofilm-coated evaporator coils. The combination of high humidity and long run times in our mild climate lets biological films establish themselves on coils that would stay cleaner in a drier or colder region. This is why coil treatment matters here in a way it doesn’t everywhere.
Pricing for HVAC Cleaning in Alderwood Manor, WA
We’re straightforward about what things cost. A full HVAC cleaning in Alderwood Manor typically runs $280-$650. Evaporator coil cleaning alone is $180-$340. Blower cleaning runs $180-$320. Air handler cleaning is $240-$420. Coil treatment is included in our full system service or available separately at $85-$140.
What moves the price? Accessibility matters. A unit in a cramped crawlspace off 196th St SW takes longer than one in a spacious utility closet. The condition of the system matters too. A blower wheel with years of biofilm buildup requires more time than one that’s been maintained. We show you the camera footage before we quote, so you see what we see. The price we give is the price on the invoice. No bait coupons, no changes at the door.
We also offer a $89 Seasonal Tune-Up that includes basic cleaning and inspection, plus our permanent 5% Senior and Veteran discount. Call (833) 700-5198 for an exact quote. Estimates are free.

FAQs - HVAC Cleaning in Alderwood Manor
The mold grows in the hidden sections. Alderwood Manor’s dense alder and big-leaf maple canopy drops leaf debris that gets pulled into crawlspace return-air intakes, where it compresses into moisture-holding mats in the ductwork you can’t see from the vent covers. The sustained humidity from our marine climate then feeds mold colonies in those hidden sections. Camera inspection finds what eyes can’t. Call (833) 700-5198 and we’ll show you.
Every 3 to 5 years for most homes, and every 2 to 3 years if you have original or single-replacement ductwork from the 1960s-1980s. The combination of aging systems and our persistently damp winters accelerates buildup here compared to drier climates. Homes with heavy tree cover or known moisture issues should consider more frequent inspection. We offer free evaluations to help you set the right schedule.
Yes. We use Rotobrush systems for mechanical agitation in ductwork, along with Nikro and Abatement Technologies vacuums for debris extraction. This combination handles the compressed organic mats and biofilm we commonly find in Alderwood Manor’s older homes. The equipment is professional-grade, not the rental units sold to homeowners.
Often yes, if the smell originates in the ductwork. In 1970s split-levels around Alderwood Manor, we find the mustiness typically comes from decomposed leaf debris in return plenums and biofilm on the blower wheel or evaporator coil. Cleaning these components removes the source. If the smell persists, we’ll tell you. We don’t sell what you don’t need. Call (833) 700-5198 for a free inspection.
Yes. Our full HVAC cleaning service includes both the evaporator coil and the blower wheel. These are the two components most affected by Alderwood Manor’s damp climate, and cleaning one without the other leaves the job half done. We verify both with camera inspection before and after. The 90-Day Done Right Promise covers everything we touch.
