Dryer Vent Maintenance in Houston, TX

Why does my dryer need two cycles in July?

Usually the vent, not the dryer. Houston air is already saturated in summer. The dryer pushes damp air into a long attic duct. That duct heats up, then cools after the cycle. Moisture condenses on the metal wall. Lint sticks to it and turns to paste. Paste does not vacuum out. It has to be brushed loose along the full run.

Run type decides most of the job. A postwar ranch or bungalow often has a short sidewall run, four to eight feet, straight out. Those clean quickly. Two-story subdivision homes are different. Twenty to thirty-five feet up through the attic to a roof cap. Every elbow added to clear a truss collects a ring of lint. Condo and townhome laundry closets share long horizontal chases, and access is the hard part.

We check the termination from outside too. Roof-cap screens trap lint. Birds and wasps build in open hoods. A blocked cap shows up as a scorched-lint smell or a tripped thermal fuse.

Behind the dryer, crushed foil in a tight closet is common. Rigid metal replaces it. Then airflow gets checked at the cap, not assumed.
