HVAC & air ducts built around Mount Vernon houses
Most Mount Vernon winters are mild and wet, but a few times a season cold air pours down from the Fraser River valley and the wind picks up across the flats. Those are the days when an undersized heat pump struggles, an old furnace runs nonstop, and drafty rooms on the windward side of the house never warm up. We look at how your home is built and where it sits, from a hillside house in Eaglemont to a rambler on the valley floor, and size the heating system for those cold stretches as well as the ordinary damp days in between.
Ducts in Mount Vernon homes often run through crawl spaces that stay damp all winter, and on the valley floor they can sit close to rising groundwater. Uninsulated or separated ducts there lose heat and pull musty air into the house. We replace failing runs with sealed, insulated ductwork hung up off the soil. Fine dust from nearby farm fields also collects in older duct systems, so we check filters and returns. For homes without ducts, or for additions and converted farmhouse spaces, ductless mini-splits provide zoned heating and cooling without major construction. Photos show you the ducts before and after.

Local conditions
What Mount Vernon throws at attics and crawl spaces
The houses
Mount Vernon's older homes climb the hill east of downtown: early 1900s Craftsman houses, cottages and farmhouse-style homes, many with low crawl spaces, partial basements and small attics. West Mount Vernon, across the Skagit River, and the flatter parts of town have post-war ramblers and 1960s and 1970s homes, mostly on crawl spaces built close to the valley floor. Growth since the 1990s moved up the eastern hills, where Eaglemont and Skagit Highlands have newer two-stories with truss attics, vaulted rooms and blown-in insulation. Farmhouses on the valley edges add their own mix of additions and old outbuildings.
The weather
Mount Vernon sits on the Skagit River where the valley opens onto the delta farmland. The low ground along the river has a high water table in winter, and fog settles over the fields on calm mornings. Cold northeast winds can blow down from the Fraser River valley during winter outbreaks, and the rainy season runs from fall into spring. Homes on the eastern hills get more wind and tree cover.
The wildlife
Farmland surrounds Mount Vernon, and mice and Norway rats live in the fields, barns and ditches. When fields are harvested and plowed in fall, rodents move toward buildings for shelter. River dikes and drainage sloughs give Norway rats burrowing ground. Roof rats and squirrels are more common in the wooded hill neighborhoods, and raccoons travel the river corridor.

FAQ
HVAC & air ducts in Mount Vernon: FAQ
Still unsure? Call (800) 674-4933 and talk it through with us.
Do heat pumps work in Mount Vernon's cold snaps?
Modern heat pumps work well through most Skagit Valley winter weather, including cold, windy days, when they are sized correctly. Many systems include backup heat for the coldest stretches. We look at your home's insulation, air sealing and exposure to wind before recommending a size, and explain how it will handle cold weather.
Should I have my ducts inspected if my house is on a crawl space?
Yes. In crawl space homes, ducts are exposed to moisture, rodents and physical damage. A separated joint or a chewed duct can leak heat and bring crawl space air into the house. We inspect the duct runs during a free visit and photograph their condition.
