UV Air-Purification Light Installation in Cypress

Not by itself, and we'll never claim otherwise. Air moves past the lamp too quickly for much single-pass effect; UV's real work is keeping continuously wet surfaces — coil area, drain pan — clean, which prevents the microbial growth and odor that start there. Think of it as surface hygiene that complements filtration, not a force field.

Annually, as a rule. Germicidal output fades long before the visible glow does, so a lamp can look alive while doing little. We put a dated label at the unit when we install, show you the swap procedure, and the replacement is a simple, inexpensive routine from there.

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.
