Fast, Reliable Air Duct Cleaning Across Boulevard Park
Air duct cleaning in Boulevard Park typically runs $350-$650 for a full residential system, with most jobs completed in a single visit by our Air Duct Cleaning team. We’re usually on-site within 24 hours of your call, and every job starts with a camera inspection so you see exactly what we’re dealing with before we lift a single tool.
We’ve been driving to Boulevard Park since 2012, long before Sea-Tac became the West Coast’s busiest hub. Our technicians know the post-war ranches along 42nd Ave S, the split-levels near the Duwamish River trail, and the tight crawlspaces beneath homes in the 98168 ZIP code. That local knowledge matters when your ducts were last touched during a Port of Seattle sound insulation retrofit and nobody documented what got moved where.

Why Bellows Air Duct & Vent Co. of Seattle Is Boulevard Park’s Preferred Air Duct Cleaning Company
Boulevard Park homeowners call us because we’ve earned a strong local reputation over four decades of showing up when we say we will and standing behind our work. Our 90-Day Done Right Promise is stamped on every job in writing - if it’s not right, we return at no charge, no paperwork, no arguing.
We answer calls with a live person, 24 hours a day. Not a voicemail tree. Not an app. A real person who can dispatch a background-checked, uniformed technician to Boulevard Park, usually same-day or next-day.
Our pricing is disclosed upfront before work begins. The number on the phone is the number on the invoice. No bait coupons, no scare tactics, no price changes at the door. That’s been our founding promise since Colin Merritt built this company on the idea that a square deal shouldn’t require a law degree to understand.
We know Boulevard Park’s housing stock - the 1950s Boeing worker ranches with original stamped sheet-metal ducts, the 1960s ramblers with early fiberglass flex runs, the RSIP-retrofitted homes with hybrid HVAC configurations that confuse standard cleaning protocols. Generic duct cleaners miss what we catch because they don’t know this neighborhood’s specific history.
Our Air Duct Cleaning Services in Boulevard Park
Residential Duct Cleaning
Most Boulevard Park homes were built between 1950 and 1972 for Boeing and airport workers, and many still run on original ductwork that predates modern sealing standards. Our residential service starts with a full video inspection, then uses Rotobrush and Nikro equipment to agitate and extract debris from every supply and return branch. We pay special attention to RSIP-modified systems where returns were re-routed through walls without replacing the original trunk lines.
A typical residential cleaning in Boulevard Park runs $350-$550 for a single-system home, $550-$650 for larger ranches with basement and main-floor units. Call (833) 700-5198 for an exact quote - estimates are free.
Commercial Duct Cleaning
Airport-area businesses along Military Road S and in the light industrial pockets near the Duwamish deal with the same elevated particulate load as residences, multiplied by higher occupancy and longer HVAC run times. We clean commercial systems for restaurants, small offices, and warehouse spaces in Boulevard Park and surrounding areas, with scheduling that minimizes disruption to your operations. Most commercial jobs run $800-$2,400 depending on system complexity and square footage.
Supply Duct Cleaning
Supply lines in Boulevard Park’s older homes often suffer from accumulated jet-exhaust particulates that standard filters can’t catch. Our supply duct service removes this fine debris from every register back to the plenum, with before-and-after camera documentation. We flag any disconnected or kinked flex sections that restrict airflow to specific rooms - a common issue in RSIP-retrofitted homes where wall insulation work disturbed original duct routing.
Return Duct Cleaning
Return ducts are where Boulevard Park homes hide their worst problems. The negative pressure pulls in unfiltered air through every gap, and in RSIP-retrofitted homes, we’ve found abandoned flex-duct sections in attics and crawlspaces that were never properly sealed or removed. These become debris reservoirs that recirculate particulates every time the system cycles. Our return duct cleaning includes full video inspection of the return path, extraction of accumulated material, and sealing recommendations where we find air leaks.
Full System Cleaning
For homes with original 1950s sheet-metal or early flex ductwork, a piecemeal approach misses the interconnected problems. Our full system cleaning covers supply trunks, return trunks, all branch lines, registers, grilles, and the air handler cabinet. We document everything with camera footage before and after. Most Boulevard Park full-system jobs run $550-$850 and are completed in one visit.
Video Inspection
Every Bellows job starts here. We run a high-resolution camera through your ductwork to identify disconnected sections, debris buildup, mold growth, and structural issues. In Boulevard Park, this step is non-negotiable - the RSIP retrofit history means we regularly find conditions no homeowner could detect otherwise. The inspection itself is included with any cleaning service, or available standalone for $150-$250.

Trusted Brands We Service in Boulevard Park
We maintain professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, and Honeywell - the same brands serious HVAC contractors specify for commercial installations. For Boulevard Park homeowners with Aprilaire or Honeywell whole-house air cleaners integrated into their duct systems, we stock local replacement parts and can service these units during the same visit. That means no waiting on shipped components, no second appointment, no extra trip charge. Most filter replacements and air cleaner servicing are completed while the duct cleaning is underway.
Common Air Duct Cleaning Problems We See in Boulevard Park Homes
- RSIP retrofit remnants: The Port of Seattle’s Residential Sound Insulation Program modified HVAC layouts in hundreds of 98168 homes without always replacing the underlying duct systems. We regularly discover disconnected or kinked flex-duct sections in attic and crawl-space runs that were abandoned when returns were re-routed - hidden debris reservoirs that no previous inspection flagged.
- Elevated particulate loading from jet exhaust: Boulevard Park sits directly beneath Sea-Tac’s busiest flight corridors. The continuous ultrafine particulates from jet exhaust accumulate in ductwork far faster than in any other King County neighborhood not under a flight path. Filters clog sooner. Ducts need more frequent cleaning.
- Condensation-trapped mold growth: The Pacific Northwest marine climate keeps humidity elevated from October through April, and the tightened building envelopes from RSIP insulation upgrades trap that moisture inside duct cavities. Poorly sealed connections from retrofit work accelerate mold and dust-mite colonization in systems already stressed by airport particulates.
- Original sheet-metal deterioration: Those 1950s stamped sheet-metal ducts weren’t built to last seventy-plus years. Seams separate, internal lining degrades, and rust forms in crawlspaces where groundwater fluctuates with the Duwamish tide. We assess whether cleaning is viable or whether section replacement makes more sense.

FAQs - Air Duct Cleaning in Boulevard Park
Homes beneath Sea-Tac’s flight corridors typically need duct cleaning every 2-3 years rather than the standard 3-5 year interval. The ultrafine particulates from jet exhaust pass through standard filters and accumulate in ductwork at rates we’ve measured at 40-60% higher than comparable homes outside the flight path. If you notice more frequent filter changes or a persistent fine dust layer on surfaces, your system is telling you something. Call (833) 700-5198 for a video inspection and we’ll show you exactly what’s inside.
Check whether your HVAC contractor performed a full duct inspection after the retrofit was completed - most did not. The RSIP program focused on windows, wall insulation, and noise reduction, not duct integrity. We’ve found homes where returns were re-routed through new wall cavities while the old flex-duct was simply abandoned in the crawlspace, creating a debris reservoir that recirculates through the system. A video inspection is the only way to confirm your duct layout matches what the RSIP contractors left behind. We offer this as a standalone service or included with any cleaning.
Yes, with proper assessment first. Original stamped sheet-metal ducts in Boulevard Park’s post-war ranches can be cleaned successfully if seams are intact and internal lining hasn’t degraded. We camera-inspect every section before agitation to identify rust, separation, or lining damage that could be worsened by cleaning. Where we find deterioration, we’ll show you the footage and discuss whether section replacement or sealing makes more sense than cleaning alone. We’ve serviced dozens of these systems in Boulevard Park - we know what holds up and what doesn’t.
More common here than in drier inland neighborhoods, yes. The combination of Pacific Northwest marine humidity and RSIP-tightened building envelopes creates condensation inside duct cavities, especially in poorly sealed retrofit connections. We find mold and dust-mite colonization in roughly one-third of Boulevard Park homes we inspect, concentrated in crawlspace returns and attic trunk lines where temperature differentials are greatest. Our cleaning protocol includes antimicrobial treatment where indicated, with documentation you can provide to insurers or inspectors. Call (833) 700-5198 if you smell mustiness when the system cycles - that’s often the first sign.
Yes. We clean commercial systems for restaurants, offices, and light industrial spaces along Military Road S and throughout the Boulevard Park commercial corridor. Airport-area businesses face the same elevated particulate challenges as residences, with higher occupancy adding to the load. We schedule around your operating hours, provide full documentation for facility managers, and meet any insurance or lease requirements for HVAC maintenance. Most commercial quotes are provided same-day after a brief site visit. Call (833) 700-5198 to schedule.
