Supply & Return Duct Cleaning in Cypress

The camera decides, not a hunch. We scope the whole system first; if debris is concentrated in the returns or specific branches, we clean those and document the rest as verified clean. If footage shows buildup everywhere, we'll say a full cleaning is the honest recommendation — with the photos to prove it.

Because they run upstream of the filter. Returns pull raw room air — dust, pet hair, fibers, pollen tracked in on shoes — straight into the ductwork before anything filters it. Supplies only see air the filter has already scrubbed. That asymmetry is why return-side cleaning is often the smartest partial job.

Look in the attic with a flashlight. Original runs from that era usually share one jacket color and one style of connection throughout, and a replacement shows up as a newer jacket, different tape or mastic, sometimes a different diameter into the same boot. A house with two vintages side by side has had partial work, and knowing which part matters.

Usually yes for particles, provided it seals. A deep media cabinet filters far better than a one-inch filter without choking the blower, but the door gasket has to close properly or air simply goes around it. Check the gasket and the latch, and note that these get changed on a longer interval than a thin filter, not a shorter one.

Have it inspected, not cleaned. Twenty years in a Cypress attic is long enough for dried mastic, separated boots and compressed insulation, all of which you would rather know about. Whether a cleaning follows depends on what the camera shows, and in a house with no symptoms it quite often does not.
