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.

AfterAir Duct Cleaning Company in Kent, WA
Air duct cleaning in Kent, WA typically costs $350 – $650 for a whole-home system and should include both supply and return lines, plus the main trunk. Kent’s location in the Green River Valley creates unique moisture problems that make professional duct cleaning here different from drier markets. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews handle the valley’s humidity-driven mold issues, aging post-war ductwork, and flood-damaged crawlspace runs that standard cleaning won’t fix. Call us at (361) 326-5060 for a written estimate before any work starts.
Why Kent Homes Are Different
Kent sits in the Green River Valley, where the damp marine air and winter flooding create some of the highest indoor humidity levels in the Puget Sound region. That moisture feeds mold and mildew in ductwork far more aggressively than in Seattle or Bellevue, making Kent duct cleaning as much about moisture control and microbial remediation as it is about dust removal.
Much of Kent’s housing was built during the post-war boom and the 1980s – 90s suburban expansion. The mid-century ramblers and split-levels have original sheet-metal ducts prone to rust and loose asbestos-wrapped joints. The two-story tract homes from the 1990s run flexible duct that sags and collects debris where it dips between joists. In Kent’s East Hill and Panther Lake neighborhoods, many 1960s – 70s homes have ductwork routed through unsealed crawlspaces that flood during heavy rain, leaving behind a musty, silt-like residue that standard vacuuming won’t remove. Technicians often have to sanitize and reseal duct runs after water events.
Kent’s wet, mild winters and humid springs mean HVAC systems run less continuously than in hotter or colder climates, allowing dust and biological growth to settle in ducts during long off-cycles. The valley’s occasional flooding events can introduce silt and moisture into crawlspace ductwork, requiring decontamination beyond routine cleaning.

Air Duct Cleaning in Kent
We clean supply and return ducts, main trunks, and registers using Rotobrush rotary brush systems and Nikro negative-air machines that pull loosened debris out of the system rather than pushing it deeper. In Kent, we pay special attention to microbial growth in humid duct runs and silt residue from crawlspace flooding. Every job gets a written price before we start and before-and-after photos of your own ducts. Air Duct Cleaning in Kent
Dryer Vent Cleaning in Kent
Lint buildup in dryer vents is a leading cause of house fires, and Kent’s older homes often have long vent runs through unconditioned crawlspaces where condensation mixes with lint to form dense blockages. We clear the full run from dryer to termination, inspect for proper airflow, and note any sagging flexible duct that needs replacement. Dryer Vent Cleaning in Kent
Duct Sealing in Kent
Leaky ducts waste heated and cooled air into attics and crawlspaces, but in Kent the bigger problem is unsealed returns pulling musty, flood-exposed air back into your living space. We seal joints and seams with mastic and proper mechanical fasteners, then pressure-test to verify the seal holds. Duct Sealing in Kent

FAQs About Air Duct Cleaning Company in Kent
No permit is required for routine duct cleaning. Duct sealing that involves modifying or extending the HVAC system may need a permit from the City of Kent; we handle the paperwork when it applies and note it in your written estimate. Call (361) 326-5060 if you’re unsure whether your job qualifies.
We prioritize flood-related calls for existing customers and aim to inspect within 48 hours when water has contacted ductwork. We do not promise same-day dispatch, but our phones are answered by a live person 24/7 to schedule the earliest available Kent crew. Fast response matters because mold colonies establish in damp ducts within 48 – 72 hours.
Most Kent HOAs do not regulate interior ductwork, but some condo and townhome associations in Meridian Valley and newer developments require notice for any work that affects common HVAC infrastructure.
