Duct Sanitizing & Antimicrobial Treatment
EPA-registered antimicrobial treatment — after cleaning, never instead of it.
Learn moreIn a Texas cooling season, the area around your evaporator coil stays wet for months — and continuously damp surfaces are where microbial growth actually starts. A properly placed UV-C lamp bathes those surfaces in germicidal light and keeps them markedly cleaner. We're straightforward about what UV does and doesn't do: it helps keep wet components clean and can knock out that stale 'wet sock' odor; it is not a substitute for filtration, ventilation, or duct cleaning. We size the lamp to your plenum, mount it clear of wiring and plastics, wire it safely, and show you the annual bulb-change routine.
Prices shown are starting estimates and may change with the condition, access, and scope we find on site. Only a written quote from an on-site visit is a price we commit to.
UV air purification — UVGI, in industry shorthand — uses germicidal ultraviolet light to keep HVAC surfaces clean. Here's the honest physics: air moving past a lamp travels too fast for much single-pass effect, but surfaces sitting in continuous UV exposure are a different story. During a Texas cooling season your coil area and drain pan stay wet for months, and continuously damp surfaces are where microbial growth establishes. A lamp positioned to bathe those surfaces keeps them markedly cleaner and heads off the stale odor that growth produces. It complements filtration and cleaning; it replaces neither.
At Prime Air Duct Experts, a uv air-purification light installation 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.
Camera duct inspectionWe examine your plenum and coil arrangement to confirm a lamp can actually reach the wet surfaces that matter.
The lamp is aimed at the damp components, with plastics and wiring shielded — UV degrades what it shouldn't be pointed at.
A clean electrical connection, a full operation check, and confirmation that no UV light escapes the cabinet.
You get the bulb-replacement schedule, a dated install label at the unit, and a plain explanation of what to expect.
We've worked on 0+ DFW homes over 15+ years. Every job — a single register or a whole-home system — runs the same way: trained technicians, written quotes, before-and-after photos, warranty in writing.
Honest scoping: we tell you what UV will and won't do before you spend a dollar
Placement engineered for surface exposure, with wiring and plastics shielded from UV degradation
Clean, safe electrical connection and a full operation check before we leave
A realistic maintenance plan — germicidal bulbs fade and need annual replacement
Family-owned, NADCA ACR-standard, EPA-guided. We're the team you call when you want it done right the first time — no rotating subcontractors, no upsell pressure, no surprises. Same techs, same trucks, same standard.

Maybe not — and we'll be the ones to tell you. EPA guidance says duct cleaning is warranted in three situations: visible mold, vermin in the ducts, or significant dust and debris buildup. Not on a calendar, not automatically every few years. Our $99 camera inspection checks your system against those conditions and gives you a straight verdict with photos. A meaningful share of inspections end with 'not yet, re-check in a couple of years' — and that answer costs you $99, not $600.
A full-system source-removal cleaning starts at $349, targeted supply-and-return work at $199, and a camera inspection at $99. Those are honest starting points, not bait: your exact quote is confirmed after we look at the system on camera and before any work begins, and it doesn't change mid-job. Add-ons like sanitizing ($149) or a UV light ($399) are offered only when the footage shows a real indication — our technicians don't earn commissions.
Three to five hours for a typical single-system home. The honest variables are the number of runs, attic access, duct type, and how much debris the system is carrying — a two-system two-story takes longer than a compact ranch. We'd rather quote you a real window than promise a ninety-minute miracle, because whole-home source removal physically cannot be done in ninety minutes. You'll get a specific time estimate with your quote, and the system is back on the moment we finish.
There's no honest fixed schedule, and we won't invent one. Ducts need cleaning when their condition says so — after a renovation, a pest issue, a moisture event, or gradual buildup that's now visible on camera. Some systems go a decade staying respectable; others load up in three years because of construction next door or a heavy-shedding pet. The economical habit is an inexpensive camera inspection every few years: it either buys you peace of mind or catches the problem while it's a targeted cleaning instead of a full one.
Here's the careful answer. Cleaning removes the reservoir of settled dust, pollen, and dander that your system can re-circulate — in Texas, that reservoir includes cedar, oak, and ragweed seasons past. What it won't do is cure allergies or stop new pollen from entering the house, and EPA notes that duct cleaning has never been conclusively shown to prevent health problems. We treat it as hygiene, not medicine: empty the reservoir, then pair it with the right filter, which often matters just as much. Anyone promising more than that is selling.
