Dual-Lamp UV-C System in San Antonio, TX
Some systems need more than a coil lamp. Where a home has had repeated microbial regrowth, a musty return, or a coil that fouls again within a season, we install a two-lamp UV-C system: one lamp aimed at the evaporator coil where moisture actually sits, and a second in the supply air stream. We are straightforward about the difference — the coil lamp is the one carrying most of the work, because continuously wet surfaces are where growth starts and where sustained exposure does something measurable. Air-stream lamps see air for a fraction of a second, so we position and size them for what that can realistically achieve rather than overselling it. Before we mount anything we check what the light will strike: UV-C degrades plastics, flex-duct liner, and some insulation over time, so lamp placement, shielding, and material compatibility are part of the install, not an afterthought. Every install gets a service-door safety interlock so the lamp cannot run with the cabinet open, plus a labeled annual bulb-change date — output falls off long before the bulb looks dead. Serving San Antonio (110 ZIP codes, 1470k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · San Antonio, TX
San Antonio runs on electricity rather than gas. The large majority of homes heat with a heat pump or resistance strips, and with winters this short the system is effectively a cooling machine nine or ten months of the year. That concentrates wear and dust at the blower and the indoor coil rather than deep in the branch runs, and it is where we start. The second half of the picture is the inner loop. A substantial share of the housing inside 410 predates 1980, ducted through vented attics with thin insulation and served by a single return grille sized for a much smaller blower than anything sold today. Starved returns are the most common finding in those houses, and adding return area improves comfort and filtration more than a cleaning does. Outside the loop, pale limestone and caliche dust from ongoing construction gets pulled in wherever the return side leaks.

Scoped from a camera inspection
At Prime Air Duct Experts, a dual-lamp uv-c system is never guesswork. We scope every job from a camera look inside the ducts first — weighed against EPA guidance on when the work is actually warranted — so what you approve is matched to what your system actually needs, with the photos to prove it. And if the camera says the work isn't needed, we tell you that instead.
