A duct system in Mukilteo 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.
Heat pumps are everywhere in Washington now, and they move air more hours of the day than the furnaces they replaced. More fan hours means the dust load in the ductwork gets delivered more often - and filters and ducts both earn attention sooner.
Plenty of Mukilteo houses pair an original metal trunk with flex additions from remodels across the decades. Each era collects and leaks differently, returns are often undersized, and an inspection maps the patchwork honestly before anyone proposes work.
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 Snohomish 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.

In Mukilteo, 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 Mukilteo 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 Snohomish County. Cleaning the trunk and returns, with a fresh filter, is how most households close out a smoke season indoors.
Rooms that lag the thermostat, long heating cycles, dust returning days after cleaning and weak flow at far registers. Under Mukilteo homes, separated crawlspace joints and unsealed returns are the standing findings, and mastic sealing is the lasting fix.
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.
