HVAC & air ducts built around Marysville houses
Most newer Marysville homes were built with a gas furnace and flexible ducts running through the attic or crawl space. Flex duct is quick to install, but it's easily crushed, kinked or pulled loose, and rodents chew through its plastic jacket and insulation. A single disconnected run can send heated air into the crawl space for years while a bedroom stays cold. Comfort complaints in these homes often trace back to the ducts rather than the furnace, which is why we inspect them before recommending new equipment. Many of these systems were also installed without any cooling at all, and summer heat now makes upstairs bedrooms hard to sleep in.
When we inspect, we follow every duct run we can reach, check connections at the boots and the plenum, look for crushed or sagging sections, and photograph rodent damage. Damaged runs get replaced, connections get sealed, and new ducts are properly supported and insulated. If your furnace is aging or you want cooling, we can add a heat pump that uses the same ducts, replace the furnace and AC, or put a ductless mini-split in a room the system doesn't reach. Paired with rodent sealing in the attic and crawl space, the new ductwork stays intact. You get photos of every run we replaced and every joint we sealed.

Local conditions
What Marysville throws at attics and crawl spaces
The houses
Marysville has grown fast, and much of its housing is recent. Downtown and the older blocks near Ebey Slough hold modest homes from the early and middle 1900s, many on low crawl spaces. Post-war ramblers and 1970s split-levels spread out from there. The big wave came from the 1990s on, when Sunnyside, Whiskey Ridge, Getchell and Cedarcrest filled with two-story tract homes on crawl spaces, with blown-in attic insulation and flexible ducts in the attic or crawl space. Manufactured homes and older farmhouses remain on the edges of town.
The weather
Marysville sits at the north edge of the Snohomish River delta, with Ebey Slough, Quilceda Creek and Allen Creek running through low ground. The flats get fog and stay damp through winter, while homes on the hills to the east catch more wind. The area also sees convergence zone storms that drop heavy rain or snow in short bursts. Soil on the lowlands holds water well into spring.
The wildlife
Farm fields, sloughs and fresh construction edges surround many Marysville neighborhoods. Norway rats live along ditches, sloughs and farm buildings, and they move into new subdivisions as fields are cleared. Mice come indoors when crops are harvested and nights cool. Roof rats, squirrels and raccoons work the wooded ravines and hillsides.

FAQ
HVAC & air ducts in Marysville: FAQ
Still unsure? Call (800) 674-4933 and talk it through with us.
How do I know if a duct is disconnected?
Signs include one room that's always colder or warmer than the rest, weak airflow at a register, rising energy bills, and a crawl space or attic that feels warm while the heat is running. The only way to confirm it is to look. We follow the runs during an inspection and photograph any loose or damaged sections.
Should I replace flex duct with metal duct?
Not necessarily. Properly supported, sealed and insulated flex duct works well in many homes. Rigid metal is more durable and resists crushing and chewing, so it can make sense for main trunk lines or crawl spaces with a rodent history. We recommend the material based on where the duct runs and what damaged the old one.
