Dryer Vent Cleaning in San Jose, CA

Dryer vent cleaning is one of the most straightforward residential maintenance tasks, and one of the most reliably skipped. In San Jose, where a significant share of housing is townhomes and attached single-family homes, dryer vent ducts are often longer and have more bends than in detached homes with short exterior wall runs. Longer ducts accumulate lint faster and are more likely to have restrictions develop in multiple sections.

We service dryer vents in all residential configurations — short runs through an exterior wall, longer runs through the attic or under the floor, and installations in multi-story buildings. The process is consistent: clear the full length of the duct, verify airflow at the exterior, and check that the vent cover is functioning correctly.

Signs Your Dryer Vent Needs Cleaning

• Clothes take more than one cycle to dry

  A normal load that used to dry in one cycle but now routinely needs two is the most common indicator that the vent is restricting airflow.

• The dryer runs unusually hot

  A dryer exterior or the laundry room that is noticeably hot during a cycle suggests heat is not escaping through the vent properly.

• A burning smell during drying

  Any burning smell from a dryer should be treated as a warning. Stop using the dryer and schedule a vent cleaning — lint in a restricted duct can ignite from normal drying heat.

• The exterior vent flap does not move

  During a drying cycle, the exterior vent cover should open with airflow. If it stays shut or barely moves, the duct is restricted.

• More than a year since the last cleaning

  Regular cleaning is the right interval for most households. If you do not recall the last cleaning, it has likely been too long.

Why Lint Buildup Is a Problem

Lint is highly flammable. The U.S. Fire Administration attributes roughly 2,900 residential dryer fires annually to failure to clean dryer vents — making it one of the most preventable causes of home fires. Once lint has packed a duct over years of use, a single normal drying cycle can generate enough heat to ignite the accumulated material.

Beyond fire risk, lint restriction forces the dryer to work harder per load — increasing energy use and wearing out mechanical components faster. Most homeowners who schedule a first professional cleaning after years of only cleaning the lint trap are surprised by how much material has accumulated in the duct itself.

In San Jose townhomes and attached homes with longer duct runs, the buildup point is often in a bend or elbow fitting where lint tends to catch and accumulate faster than in straight sections.

What Dryer Vent Cleaning Includes

We clean the complete dryer vent system from the dryer exhaust port to the exterior vent cover — the full length of the duct run, including bends and the exterior cap.

Some vent problems are structural rather than lint-related — a damaged duct section, improper flexible duct material, or a disconnected joint anywhere in the run. A cleaning does not resolve those; they are a repair.

Dryer Vent Inspection and Airflow Check

A dryer vent inspection goes beyond the cleaning to assess the complete duct system — total run length, number of bends, duct material, and compliance with the California Mechanical Code requirements for maximum duct length and bend count. Many older San Jose installations, including those in 1980s and 1990s townhome developments, use foil accordion duct that does not meet current fire code standards.

If your dryer has had persistent performance issues despite regular cleaning, or if the duct has never been professionally inspected, a full inspection is the right starting point — a separate service from a cleaning.
