Full-System Air Duct Cleaning
Whole-home source-removal cleaning of every supply and return run.
Learn moreThe plenums — the supply box that feeds every duct and the return box that collects air coming back — sit at the heart of the system and catch its heaviest debris. Because every cubic foot of conditioned air passes through them, dust, liner fragments, and microbial staining here matter more than anywhere else in the ductwork. We open both boxes with the system off, HEPA-vacuum and hand-wipe the interiors, inspect liner and insulation condition, and photograph the result. Often paired with a filter upgrade, and often the highest-value two hours you can spend on an older system.
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.
The plenums are the two sheet-metal or duct-board boxes joined to your air handler: supply on the leaving side, feeding every duct in the house, and return on the entering side, collecting everything the returns bring back. All of your conditioned air passes through both, every cycle, which makes them the highest-traffic surfaces in the entire system — and, on older systems, the place where liner degrades, dust cakes, and musty odors take hold. Cleaning them means opening the boxes with the system off, HEPA-vacuuming and hand-wiping the interiors, inspecting liner and insulation, and resealing the access properly.
At Prime Air Duct Experts, a plenum & return-box cleaning 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 inspectionA plenum & return-box cleaning 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.
The ACR standard treats the air handler's plenums as part of the air-conveyance system, cleaned by source removal and verified — which is exactly how we handle them.
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.
The system is shut off and both plenum boxes are opened carefully, preserving panels and seals for proper closure afterward.
Interiors are HEPA-vacuumed, then wiped down with a non-solvent cleaner safe for metal and liner surfaces.
Liner and insulation condition is documented. If degraded duct board needs replacing — an HVAC contractor's job — we say so plainly.
Access points are closed with UL 181-listed tape, a fresh filter goes in on request, and the photo set is yours.
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.
Hand-cleaned and photographed, not fogged and closed back up
Liner and insulation condition reported honestly — including when duct board is too far gone for cleaning to help
Access panels resealed with UL 181-listed foil tape, not whatever was rattling around the truck
Often the highest-value two hours you can spend on a system past its fifteenth year
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.
