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.

We’re not strangers to this neighborhood. Our technicians have crawled through enough Larch Way crawl spaces to recognize the patterns: the original galvanized trunk lines from the 1950s and 60s, the fiberglass ductboard that’s started to degrade, the flex runs that have gone flat or pulled loose in chronically damp conditions. We bring Rotobrush and Nikro equipment to every job, and we don’t leave until we’ve shown you camera footage of what we found and a photo of how we left your home.
Why Morton’s Air Duct Cleaning Is Larch Way’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Larch Way one house at a time, mostly through neighbors telling neighbors. Families here talk. They mention the crew that laid drop cloths before touching the floors, that worked quietly while the toddler napped, that gave a written price and stuck to it. That’s the Cedarwell Care Promise in action, and it’s how we’ve operated since Paul Adeyemi founded Morton’s in 2005.
Our response time to Larch Way is typically 2-4 business days for standard scheduling, sometimes sooner if we’ve got a crew finishing early nearby. We know the area well enough to find your house without you staying on the phone giving turn-by-turn directions. We know which streets dead-end at the Mountlake Terrace border, which lots back up to the Interurban Trail, and which homes were built in the first wave of postwar expansion versus the later 1960s and 70s phases. That local knowledge matters when you’re diagnosing why a particular system smells musty every October.
Every technician is background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values. Shoe covers and drop cloths are standard on every visit, not optional. And when the job’s done, you’ll get a photo of the clean-up before we leave, plus our 365-Day Done Right Promise in writing. If something isn’t right, we make it right. Full stop.
Commercial Air Duct Cleaning in Larch Way
Commercial Air Duct Cleaning in Larch Way covers the small professional offices, medical clinics, daycare facilities, and retail spaces that serve this residential corridor. These buildings often share the same vintage as the surrounding housing stock, with HVAC systems installed in the 1970s or 1980s that have never had proper duct maintenance. A typical commercial system in Larch Way runs $800-$1,800 depending on square footage and system complexity, with larger multi-zone setups requiring custom quotes.
Office and Clinic Systems
Medical and professional offices near the Lynnwood border often have rooftop package units with long horizontal duct runs that collect condensation and biological growth. We use HEPA-contained negative pressure and video inspection to document before-and-after conditions for your maintenance records.
Daycare and Pet-Friendly Spaces
Facilities serving children or animals need extra attention to product selection and scheduling. We use pet-safe and low-odor cleaning protocols where available, and we’ll coordinate around your operating hours so nap times and peak visit periods go undisturbed.
Air Duct Cleaning Services in Larch Way
Air Duct Cleaning Services in Larch Way start with understanding what kind of house you have and what it’s been through. Most homes here were built between the late 1940s and early 1970s, and many still run on original or minimally updated duct systems. A full residential cleaning in Larch Way typically costs $350-$650, with video inspection, source removal of biological growth, and sealing work quoted separately if needed.
Camera Inspection and Diagnostics
We camera-inspect before we quote any sealing or remediation work. In Larch Way’s crawl-space duct runs, we regularly find crushed flex connections, rust-perforated joints, and active mold colonies that vacuuming alone won’t fix. You see what we see. Then we talk about what actually needs to happen.

Full System Source Removal
Our Rotobrush and Nikro agitation tools loosen debris from duct interiors while HEPA-filtered negative pressure collects it outside your home. We clean supply ducts, return ducts, the air handler cabinet, and accessible trunk lines. For homes with biological growth, we apply appropriate remediation before sealing.

Trusted Brands We Service in Larch Way
We maintain professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we stock common fittings and repair parts that match the Honeywell, Aprilaire, and Guardsman components found in many Larch Way HVAC systems. That means faster turnaround when your mid-century system needs a repair alongside its cleaning, not a second visit two weeks later while parts ship. Our technicians train on these brands specifically, so they recognize the quirks of older Aprilaire humidifiers mounted on original furnaces, or the Guardsman air cleaner housings that need careful handling after decades of service. When you’re working on systems this age, knowing the equipment history matters as much as having the right tools.
Common Air Duct Cleaning Problems We See in Larch Way Homes
- Biological growth in original galvanized trunks. The 80-90% humidity of Larch Way’s wet season condenses inside uninsulated metal ducts, creating ideal conditions for mold and mildew that simple dust removal won’t address. We find active colonies in roughly half the pre-1970 systems we inspect.
- Crushed or disconnected crawl-space flex runs. Mid-century ranch homes here often have duct runs snaking through damp crawl spaces where settling, rodent activity, or previous repair attempts have flattened or pulled apart flex connections. The bedroom at the end of the run stays cold and smells musty because no conditioned air is reaching it.
- Rust-perforated joints recontaminating cleaned systems. Even thorough source removal fails within a season if we don’t seal the rust holes and gaps where Puget Sound humidity continually infiltrates. The crawl space stays damp; the ducts stay damp; the problem returns.
- Degraded fiberglass ductboard shedding particles. Original ductboard from the 1960s and 70s breaks down, releasing fiberglass and accumulated debris into airflow. Vacuuming the registers without addressing the deteriorating trunk material just moves the problem around.
Pricing for Air Duct Cleaning in Larch Way, WA
Most full residential air duct cleaning jobs in Larch Way fall between $350 and $650 for a complete supply and return system clean, including the air handler cabinet. Video inspection adds $75-$150. If we find biological growth requiring remediation, or disconnected and rust-perforated connections needing sealing, that work runs $200-$500 additional depending on extent and accessibility. Commercial systems start around $800 and scale with square footage and zone complexity.
We give you one flat price per system, agreed in writing before any work starts. No per-vent pricing. No add-ons after the crew arrives. What we quote is what you pay. The factors that move you within these ranges are system size, accessibility (crawl space versus basement), condition of existing ductwork, and whether remediation or sealing is needed beyond standard cleaning.

FAQs About Air Duct Cleaning in Larch Way
Larch Way’s combination of 50-70 year-old original duct systems and 80-90% wet-season humidity creates condensation inside metal and ductboard trunks that newer sealed systems simply don’t experience. The Puget Sound Convergence Zone can drop even more moisture on this corridor than surrounding areas, and uninsulated crawl-space duct runs stay damp enough to sustain mold colonies year-round. Newer homes use sealed, insulated flex duct that doesn’t have this problem. Call (323) 918-4345 and we’ll camera-inspect to see what’s growing in yours.
We regularly find rust-perforated flex connections, crushed runs flattened by decades of crawl-space activity, and active mold colonies on duct interiors and air handler cabinets. On that 1962 split-level off Larch Way near the Mountlake Terrace line, our tech found a crushed flex run to the rear bedroom and a rust-perforated connection in a chronically damp crawl space. The musty smell only cleared after we cleaned, sealed, and reconnected that run properly. Camera inspection lets us show you exactly what you’re breathing through.
Cleaning alone is rarely enough in Larch Way’s older homes if the original galvanized or flex connections have rust holes, gaps, or crush damage. The Puget Sound humidity will recontaminate the system within a season. We recommend sealing when camera inspection shows perforations, disconnected runs, or significant gaps at crawl-space joints. We’ll show you the footage, explain what sealing costs, and let you decide. No pressure either way.
We seal the system and run negative pressure with HEPA filtration during the entire cleaning process. That means debris is pulled out of your ducts and captured in our equipment, not pushed into your living space. Our technicians also isolate work areas and use contained agitation tools. The Cedarwell Care Promise includes protecting your home as carefully as we clean it.
Slow drying usually points to a clogged dryer vent, which is a separate but related service we offer. In Larch Way’s older homes, dryer vents often run through walls or crawl spaces with the same moisture and lint accumulation issues we see in HVAC ducts. A blocked dryer vent is also a genuine fire hazard due to lint buildup. We can inspect and clean your dryer vent while we’re addressing your air ducts. Call (323) 918-4345 to add it to your estimate.
