Fast, Reliable HVAC Cleaning Across Edgewood
HVAC cleaning in Edgewood, WA typically costs $280–$580 for a complete system service and is usually completed in a single visit by our owner-led team. If your Edgewood home was built during the 1970s through 1990s suburban expansion, there’s a strong chance your original forced-air system is running through a vented crawlspace that’s been absorbing valley-floor moisture for decades. We’re Richard Anderson and the team at Landmark Air Duct Cleaning Service Washington, and our HVAC Cleaning crew knows these homes inside and out — from the ranch-style layouts along Meridian Avenue E to the split-levels tucked behind Edgewood High School. We carry professional-grade Rotobrush and Nikro equipment designed for the heavy-duty residential cleaning these older systems demand, and we make the drive from our Seattle base to Edgewood regularly enough that we can usually book you within a few days.

Why Landmark Air Duct Cleaning Service Washington Is Edgewood’s Preferred HVAC Cleaning Company
Edgewood homeowners aren’t looking for a generalist who cleans ducts between furnace installs and AC repairs. They’re looking for a specialist who understands why their 1985 split-level smells musty every October when the Puyallup River valley fog rolls back in. That’s exactly what we are.
Our 732 verified customer reviews averaging 4.9 stars include dozens from Edgewood and the surrounding 98354 ZIP code area. Property managers near Milton and Fife refer us specifically because Richard Anderson, our Owner and Lead Technician, personally runs the equipment on every job. No rotating crews. No “the guy who showed up today.” Richard’s hands are on the Rotobrush, and his name is on the company.
We’ve been making the run down I-5 to Edgewood for 11 years now. We know the difference between the newer subdivisions near Edgewood Park and the original ranch tracts off 24th Street E — and we know which ones are hiding 40-year-old flex duct that’s been sitting in 70% relative humidity since the Carter administration. That local knowledge means we arrive with the right attachments, the right sealants, and the right expectations. One trip. Done properly.
Our HVAC Cleaning Services in Edgewood
Air Handler Cleaning
The air handler is the heart of your forced-air system, and in Edgewood’s older homes, it’s often working overtime to push air through deteriorating flex duct in soggy crawlspaces. We disassemble and clean the blower housing, heat strips, and drain pan — removing the mold spores, dust mite debris, and biofilm that thrive in Edgewood’s persistent valley humidity. A clean air handler means less strain on your motor and cleaner air actually reaching your registers, not just recirculating crawlspace contaminants.
Heat Exchanger Cleaning
Edgewood’s 1970s–1990s housing stock runs heavily on gas furnaces with heat exchangers that have been cycling through damp Pacific Northwest winters for 30–50 years. Soot and corrosion scale build up on exchanger surfaces, reducing efficiency and creating potential carbon monoxide risks. We inspect and clean heat exchangers with borescope cameras and specialized brushes — no cutting corners on a component this critical. Richard Anderson performs this work personally; it’s not delegated to a trainee.
Evaporator Coil Cleaning
Your evaporator coil sits in a dark, humid plenum — basically a mold buffet in Edgewood’s climate. We remove the coil when accessible and clean it with foaming agents that break down biofilm without damaging the delicate aluminum fins. For coils that can’t be removed, we use our Nikro high-pressure system with contained drainage. Either way, you’re getting back the heat transfer efficiency you’ve been losing to coil fouling.
Blower Cleaning
The blower wheel in an Edgewood home often looks like it’s been dipped in gray felt after a decade of pulling air through degraded duct insulation. We remove the entire blower assembly, clean the wheel blades individually, and balance the motor. A clean blower moves more air at lower amperage — which you’ll notice on your PSE bill and in more even temperatures from room to room.
Condenser Cleaning
Even Edgewood’s mild summers stress a dirty condenser. We clean the coil fins, straighten damage from lawn equipment and hail, and check refrigerant levels. A clean condenser in Edgewood’s marine-influenced climate runs 15–20% more efficiently than a fouled one, and it doesn’t strain the compressor into an early replacement.
Coil Treatment
After cleaning, we apply EPA-registered coil treatments that inhibit mold regrowth — particularly valuable for Edgewood homes where the coil lives in a humid environment year-round. We use products compatible with Honeywell and Aprilaire air quality systems, and we’ll tell you honestly whether your coil condition warrants treatment or if a replacement makes more financial sense.

Trusted Brands We Service in Edgewood
We maintain working knowledge of the equipment brands most common in Edgewood’s housing stock — Trane, Carrier, Lennox, Rheem, and Goodman systems dominate the 1970s–1990s installs here. For air quality upgrades after cleaning, we stock and install Honeywell electronic air cleaners, Aprilaire media filters, Abatement Technologies HEPA filtration, and Guardsman UV sanitizing systems. Having these parts on hand means Edgewood customers aren’t waiting a week for a Seattle distributor to ship. Richard Anderson specs the right combination for your actual system and your actual air quality problems — not a generic package.
Common HVAC Cleaning Problems We See in Edgewood Homes
- Partial collapse or separation of aging flex duct at connections. On a 1978 ranch home near 24th Street E, we found the original flex duct in the crawlspace had pulled apart at a duct-board connection, letting unfiltered, mold-laden air short-circuit into the living room. Using our Rotobrush system, we scrubbed the entire trunk line and sealed the gap with mastic, restoring airflow and eliminating the musty smell.
- Degraded insulation jackets on pre-2000s ductwork shedding fiberglass into the airstream. That itchy, dusty feeling when your furnace kicks on? It’s often degraded fiberglass insulation breaking down after decades of Edgewood crawlspace humidity. We document the condition and can transition you to duct repair and sealing if cleaning alone won’t solve it.
- Biofilm accumulation inside ducts from persistent valley-floor fog. Edgewood’s position along the Puyallup River valley floor means it collects marine air drainage and ground-level fog that can keep crawlspace environments at or above 70% relative humidity for weeks at a time in fall and winter, directly feeding mold and biofilm growth on the interior surfaces of aged flex duct. Unlike hillside communities in the same ZIP region, homes on the valley-adjacent flatlands rarely dry out fully between Western Washington’s rainy seasons.
- Collapsed duct sections restricting airflow to specific rooms. The southwest corner of your Edgewood ranch always runs cold? We regularly find completely collapsed flex duct in crawlspaces where the wire spiral has rusted through from moisture exposure, creating a dam of insulation that blocks airflow entirely.
Pricing for HVAC Cleaning in Edgewood, WA

What moves you within these ranges? Accessibility matters — a cramped Edgewood crawlspace with standing water takes longer than a basement utility room. Component condition matters — a coil with ten years of biofilm needs more passes than one cleaned three years ago. And honesty matters to us: if we open your air handler and find the ductwork is too far gone to clean meaningfully, we’ll show you the borescope footage and talk repair options before we charge you for a cosmetic fix. Every estimate we provide in Edgewood is free, and every quote is firm — call (877) 335-1974 to schedule yours.

FAQs — HVAC Cleaning in Edgewood
Edgewood’s 1970s–1990s housing stock was built with original flex duct in unconditioned, vented crawlspaces that sit directly above the moisture-laden Puyallup River valley floor. Decades of humidity cycling above 70% relative humidity degrades the spiral wire and insulation jacket, causing partial collapse or complete separation at duct-board connections — a failure mode we rarely see in drier upland cities like Bonney Lake or Sumner. If you’re noticing weak airflow or musty odors, collapsed duct is a likely culprit. Call (877) 335-1974 for a free inspection — we’ll bring the borescope camera and show you exactly what’s happening under your floor.
Yes, we clean HVAC systems in Edgewood’s vented crawlspaces year-round, including during the heaviest rainy months from November through February. Our Nikro equipment includes contained drainage systems and HEPA filtration that prevent moisture and debris from entering your living space during the process. We do recommend scheduling duct repair and sealing work for drier windows when possible, but cleaning itself is not season-dependent. Call (877) 335-1974 to book — we’ll work with your schedule and Edgewood’s weather patterns.
Ducts exposed to long-term high humidity typically need more than mechanical cleaning alone — we recommend coil treatment and often suggest upgrading to an Aprilaire or Honeywell dehumidification strategy as part of your overall system. The biofilm that establishes itself in chronically damp ductwork can recolonize quickly after basic cleaning if the moisture source isn’t addressed. We’ll assess your crawlspace ventilation, your duct insulation condition, and your HVAC runtime patterns to give you a realistic maintenance plan. Estimates are free — call (877) 335-1974.
Cleaning is worth it if the duct is structurally intact; if the flex duct has degraded to the point of shedding insulation or has multiple collapsed sections, we may recommend our duct repair and sealing service instead or in addition. We evaluate this honestly on every Edgewood job — there’s no value in cleaning ductwork that’s actively disintegrating. Richard Anderson will show you the borescope footage and explain whether cleaning, repair, or replacement gives you the best return. Call (877) 335-1974 for an assessment with no pressure to commit.
We use professional-grade Rotobrush brush-and-vac systems for duct interior cleaning and Nikro high-pressure equipment for coil and condenser work — the same brands specified by commercial restoration contractors, not rental-grade alternatives. Richard Anderson selected this equipment specifically for the heavy-duty conditions we encounter in Edgewood’s older housing stock, where decades of moisture damage create cleaning challenges that consumer tools simply can’t handle. For air quality upgrades, we install Honeywell, Aprilaire, Abatement Technologies, and Guardsman products. Call (877) 335-1974 to discuss what combination fits your system.
