A duct system in Washougal works through wet winters in a sealed house, often from a damp crawlspace, and increasingly alongside a heat pump. This is what we actually find here, and what we check on every visit.
Tree pollen arrives in Washougal in a rush each spring - alder, birch and cedar in turn - and coats everything for weeks. Return ducts store the season's load, and allergy households keep breathing spring pollen from the system well into summer.
Wildfire smoke reaches the Washougal area most summers now, and fine smoke particles penetrate closed homes and settle into duct dust. After the skies clear, the system keeps recirculating that residue at startup - a post-smoke cleaning is the fastest way to close the season out.
Where ducts run through the attic, blown insulation drifts against and over runs, straps loosen, and joints separate under the blanket where nobody sees them. Weak airflow to one end of the house is often an attic duct story, found on camera without disturbing the insulation.
Cool supply ducts passing through humid crawlspaces in Clark County can sweat on their outer surfaces in summer. Torn or missing insulation is usually behind it, and the dripping wets joists and subfloor - a duct repair and insulation fix, caught early on an inspection.

The visit starts with a look inside the ductwork — at the registers and at the main trunk — so the diagnosis is something you can see for yourself, and the inspection is free.

In Washougal, the usual cause is dust that has sat in damp ductwork - crawlspace runs especially - through the wet months. The first heating cycles deliver that stored smell to every room. A cleaning from the main trunk out clears the source; if the odor returns fast, the inspection checks for wet insulation or a return pulling crawlspace air.
Every few years for most Washougal homes - sooner with pets, allergy sufferers, a heat pump running long fan hours or a home that sat closed through a smoky summer. We camera-inspect free and show you the inside of your own trunk, so the decision comes from what is actually in there.
Our negative-air machine seals onto the main trunk duct and puts the whole system under suction first. Then each individual run is scrubbed on its own, so loosened dust travels toward the trunk and into the machine - never back into your rooms. We finish at the registers and show you the before-and-after on camera.
Yes - it removes the indoor reservoir. Smoke particles settled into duct dust keep recirculating at startup after the outdoor air clears across Clark County. Cleaning the trunk and returns, with a fresh filter, is how most households close out a smoke season indoors.
The ductwork is the same, but it works more hours - heat pumps move air gently and often, so a dust load gets delivered more times a day. Keeping the trunk and returns clean, and the returns sealed properly, matters more, not less, behind a heat pump.
No — and be wary of anyone who does. Every duct system is a different size and condition, so a phone price is a guess that changes at your door. Our inspections and estimates are free: a tech looks inside your actual ductwork first, then gives you one clear price before any work starts.
