Dryer Vent Cleaning for Alpine Homes

Lint is fuel. That is the whole reason this service exists. A dryer moving hot, moist, lint-laden air through a restricted duct is a heat source next to an accumulation of fine combustible material, and the appliance has no way of telling you the duct is packed.

Why big houses have worse ducts

Alpine's housing runs to large custom homes, and large homes put the laundry room where it is convenient for the family rather than where it is convenient for the duct. A laundry in the middle of the floor plan, or upstairs near the bedrooms, can be twenty or thirty feet of duct from the nearest exterior wall, with three or four elbows to get there.

Every one of those elbows costs airflow. The usual guidance treats a ninety-degree bend as the equivalent of several extra feet of straight duct, and manufacturers set a maximum equivalent length for a reason. Past that point the dryer cannot clear its own exhaust, the moisture stays in the drum, and the lint that should have been carried outside settles at the first bend instead and starts building a plug.

Long runs are also more likely to pass through unconditioned space. A duct crossing a cold attic in an Alpine January condenses the moisture out of the exhaust, and damp lint packs down hard instead of blowing through. That is why the worst blockages we pull are rarely at the wall hood. They are twelve feet back, at the first elbow after the duct left the warm part of the house.

How we clean it and what we check

We clean the full run with a rotating brush fed from the appliance end, with a vacuum capturing what comes back, and we verify the exterior hood actually opens under airflow. A flapper stuck shut by old lint makes a perfectly clean duct useless. Where the duct is flexible foil or vinyl, we will say so: those materials sag between supports, catch lint in every ripple and are not permitted for concealed runs. Rigid metal is the fix, and on a long Alpine run it makes a bigger difference than the cleaning does.

We also check the connection behind the appliance, because a duct that has pulled loose is dumping hot moist air into the wall cavity or the laundry room. That shows up as a humid room, a musty smell, or in bad cases as staining on the drywall.

How often

Once a year is right for a normal household. Long runs, a large family, or a duct with several bends justify more frequent attention, and if drying times have crept up since last time, do not wait for the schedule.
