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.
Air Duct Cleaning Company in Sultan, WA
Sultan sits where the Skykomish River carves a narrow valley against the first rise of the Cascades. That geography does something specific to the air inside Sultan homes: it holds moisture against them for weeks at a time. We built our Sultan service around that reality, not around a generic checklist. Homes here, especially the 1970s-1990s ranch houses and manufactured homes that make up much of Sultan’s stock, collect humidity in ducts in ways drier cities like Monroe or Everett never see. If you’re looking for an air duct cleaning company in Sultan, you want a crew that understands valley fog, Cascade rainfall, and what those conditions do inside a flex-duct system. Call us at (323) 918-4345 and we’ll walk you through exactly what we’d check first.
Why Sultan Homes Are Different
Sultan receives more than 55 inches of precipitation annually, and the valley’s geometry traps persistent fog against the foothills through fall and early winter. Relative humidity hovers near or above 80% for long stretches. For a duct system, that’s not just damp air, it’s a standing invitation for mold colonization and moisture-laden debris to take hold inside trunk lines and flex runs. Older Sultan homes compound the problem. Many were built with unsealed sheet-metal joints or aging flex duct that lets humid crawl-space air seep in, where condensation forms and biological growth follows. We regularly find dark staining and damp particulate in systems across Sultan’s older neighborhoods, even in homes where the HVAC has run normally all season. Late summer adds another layer: wildfire smoke from the Stevens Pass corridor pushes fine particulate through returns and into the ductwork. By the time a Sultan homeowner calls us, the system is often carrying a full year of valley moisture and Cascade smoke. That changes how we clean here, and what we watch for.
Our Main Sultan Services
Most Sultan homeowners call us about one of two things: the air ducts carrying heated and cooled air through the house, or the dryer vent hidden behind the appliance. Both services have their own detailed Sultan pages, linked below.
Air Duct Cleaning in Sultan
Sultan’s humid valley air makes air duct cleaning here a moisture-first job. Before we run our Rotobrush system through your vents, we inspect for the damp debris and potential mold growth that Sultan’s climate encourages. We pay close attention to unsealed joints in older ranch homes and manufactured homes, where humid crawl-space air commonly enters. The goal is a system that’s actually clean, not just vacuumed. Full details on our process, what we check, and what it costs are on the Sultan service page: Air Duct Cleaning in Sultan.

Dryer Vent Cleaning in Sultan
Dryer vents in Sultan homes face a particular challenge: valley humidity plus lint equals clogs that form faster than in drier towns. We remove the accumulated lint and check the full vent run for obstructions, a job that matters more here where rodent activity can also play a role. Every Dryer Vent Cleaning in Sultan visit includes a written price before we begin and a photo of the finished work before we leave.

Pricing for Air Duct Cleaning Company in Sultan, WA
Here are the price ranges we typically see for the most common Sultan jobs. Every quote is confirmed in writing before any work begins, so the number you approve is the number you pay.
| Service | Typical range in Sultan |
|---|---|
| Air duct cleaning (whole home, up to 10 vents) | $350 - $550 |
| Air duct cleaning (larger homes, 11-18 vents) | $550 - $800 |
| Air duct cleaning (largest homes, 19+ vents) | $800 - $1,200 |
| Dryer vent cleaning | $100 - $160 |
| Dryer vent cleaning (longer runs over 15 feet) | $160 - $250 |
| Dryer vent repair or re-routing | $150 - $350 |
| Crawl space duct cleaning (per project) | $250 - $700 |
| Fiberglass duct board cleaning | $400 - $900 |

| Mold remediation in ductwork | $500 - $1,500 |
| Supply register and return boot cleaning (per piece) | $15 - $35 |
Two things push Sultan prices toward the upper end of these ranges. First is the moisture factor: if we find mold or biological growth, remediation adds labor and materials. Second is geography. Sultan’s crawl-space duct systems can be tight and awkward, and older homes often need more time to reach every register. Whatever we find, you’ll have the price in writing before we start, and the 365-Day Done Right Promise stands behind the work: if it’s not right, we return and make it right.

What Sultan Customers Say
"Spotless work. They laid drop cloths everywhere and I was honestly impressed there was zero mess at the end. Showed me the dirt they pulled out so I could see it was worth it."
- Shelby Dunham"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
- Scott Hemmings"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
