Camera Duct Inspection & Air-Quality Assessment
See inside your ducts before you spend a dollar on cleaning.
Learn moreA smell that arrives when the air kicks on is a solvable problem, because the odor has an address. We investigate methodically: camera every accessible run, open the plenums, check the condensate area for moisture and microbial staining, look for evidence of animal intrusion, and test for disconnected runs pulling attic or crawlspace air into the system — a remarkably common culprit in Texas homes. You get photos of what we find and a specific fix at a firm price, whether that's targeted cleaning, sanitizing after the source is removed, or a referral to the right trade. And when the source isn't your ducts, we say exactly that.
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.
An odor that arrives with the airflow has a source somewhere in the loop, and finding it beats masking it. The usual suspects sort into families: musty means moisture — condensation, a past leak, microbial growth; animal smells mean intrusion, present or past; an attic-like or dusty note often means a disconnected or torn run pulling unconditioned air into the system, which is strikingly common in Texas attics. We work the system methodically — camera in every run, plenums opened, condensate area checked, connections verified — until the smell has an address. Then we quote the specific fix, and if the source isn't your ducts, we say exactly that.
A duct odor investigation isn't a matter of opinion — it's measured against published industry standards. Prime Air Duct does every job to the named standards below and documents it, so the work is provably right for you, an insurer, or a future buyer. These are the industry benchmarks our procedures follow on every job.
Vermin in ductwork is one of the three conditions under which EPA says cleaning is warranted. When an investigation confirms intrusion, the cleaning recommendation that follows is EPA-aligned, not opportunistic.
Standards cited are the established industry benchmarks (NADCA, EPA, ASHRAE, UL) that our procedures follow on this service — the same method and documentation on every job, whether it's a single register or a whole-home system.
When it happens, which rooms, which registers — the odor's schedule and geography narrow the search before a tool comes out.
Every accessible run plus both plenums, photographed, with special attention to the registers the interview flagged.
Condensate area, staining, evidence of animal activity, and connection integrity — the three odor families checked in turn.
Photos of the source, a firm-priced remedy — targeted cleaning, sanitizing after removal, or a referral to the right trade.
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.
Methodical elimination, not a guess and an air freshener
Disconnected-run detection — the most-missed odor source in Texas attics
Findings delivered in photos, so you see the source rather than take our word for it
An honest 'it's not your ducts' when the evidence points elsewhere
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.
