Air Vent Cleaning in Houston, TX

Air vent cleaning in Houston homes

A disconnected return costs you more than dust. It pulls attic air straight into the blower. That air carries insulation fiber and rodent debris. Summer humidity rides along too. The coil stays wet. Growth starts on the cold plenum surface. Wait a season and you are paying for coil cleaning and a drain pan too, not just vents.

The job changes with the duct type. Pre-1970 ranch stock runs galvanized trunk-and-branch with fiberglass liner inside. Brushing degraded liner makes things worse, so that gets inspected first. Fiberglass ductboard plenums from the 1960s through the 80s shed fibers once the facing fails. They need gentle contact, not aggressive whips. Flex duct since the mid-1980s is the common case here. R-6 and R-8, draped over attic joists, sagging between supports.

We pull registers and boots. Boots are where the deposits sit. In flooded homes, floor and low-wall boots show a silt line. That tells you water height, and silt does not vacuum out of a crushed boot.

Cleaning will not fix a single undersized central return. That shows as whistling and high static pressure. Nor will it cool a bedroom at the end of a long attic run if the flex is compressed behind a kneewall. We say so rather than sell cleaning twice.
