Air Vent Cleaning in Houston, TX

What air vent cleaning actually involves in Houston homes

Waiting has a real cost here. A slipped boot collar dumps cooled air into the attic. Attic dust then gets pulled back into the return path. Insulation fiber, insect frass and gypsum dust ride that air to the blower. Indoor humidity climbs into the muggy range. Settled organic dust on duct interiors starts supporting mold. That is a remediation problem, not a cleaning one.

Registers are the smallest part of the job. The register is just the lid. Most of the load sits in the branch runs and the return plenum. In pre-1960 houses we find galvanized trunk with branch takeoffs. Internal fiberglass liner is often deteriorated. Brushing deteriorated liner makes it worse, not better. Those runs get inspected before anything touches them.

Flex duct in the attic sags between joist supports. Dust pools at the low point. Static pressure drops and the blower works harder. Cleaning a sagging run without resupporting it buys you a few months.

Some 1950s and 60s slab homes have under-slab ducts. Those take silt and moisture. We inspect boots and lower runs first in flood-affected houses.

If the evaporator coil is fouled, airflow stays bad regardless. Say so before scheduling.
