Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterGuardsman Air Duct Cleaning in Los Angeles: What to Know First
We provide independent Guardsman air duct cleaning across Los Angeles, and most homes run between $450 and $900 for a full system cleaning depending on square footage, the number of returns, and how long it’s been since the ducts were last touched. We schedule most Guardsman jobs within a week, and the written price is in your hands before a single vent is opened. No door-step revisions, no surprise line items, no pressure.
If you own a Guardsman HVAC system in Los Angeles, you already know what our air does to a house. Pollen, wildfire ash, and the fine dust that settles into everything west of the 405 end up in your ductwork. This page is for homeowners who want the full picture: what goes wrong inside Guardsman duct systems, what it costs to fix, and exactly how we clean them. Call (469) 972-3151 for a free estimate, and you’ll talk to a live person, not a phone tree.
How Guardsman Products Fail - and How We Fix Them
- Oversized return plenums on Guardsman packaged units pull harder than the filter can handle. On the Guardsman G-Series packaged gas/electric units common in Valley homes and older Los Angeles neighborhoods, the return side often draws more air than the manufacturer’s recommended filter setup is rated for. The result is filter bypass: unfiltered air sneaks around the edges and deposits a fine gray film along the return duct walls. Our fix is a full return-duct cleaning with brush agitation, followed by a conversation about filter fitment so it doesn’t come back in six months.
- Flex-duct runs on Guardsman split systems sag and collect debris at the low points. We see this constantly on Guardsman split systems installed in Los Angeles attics, where flex duct runs over rafters and dips between them. Dust, pet hair, and the occasional rodent nesting settle into those dips and stay there. A visual inspection finds them, negative-air extraction pulls the debris out, and we’ll flag any section that’s collapsed to the point of restricting airflow.
- Guardsman evaporator coils are positioned tight against the supply plenum, making coil cleaning part of the duct job. On Guardsman R-Series split systems, the evaporator coil sits close enough to the supply plenum that what accumulates on the coil ends up in the first few feet of supply duct. You can’t clean the ducts properly without addressing the coil. We include coil inspection and cleaning as part of a full-system Guardsman cleaning when the setup calls for it.
- Return grilles on Guardsman systems use oversized grille openings that let in construction dust and renovation debris. If your Los Angeles home went through a remodel, the return side has been pulling drywall dust and sawdust into the system every time the blower ran. Guardsman return grilles are not the tightest in the industry, and that dust works its way deep into the return trunk. Our video inspection shows you the before and after, so you know the work was actually done.
- Guardsman thermostat controls cycle the fan in a way that bakes fine particulate onto the supply duct walls. The Guardsman ComfortSense thermostat line runs the blower in short cycles during mild Los Angeles weather, which doesn’t give moisture and fine dust time to clear the system. Over time, that particulate adheres to the supply duct walls. It’s not a defect, it’s just how the system behaves in our climate. We address it with full supply-duct cleaning and, if it fits your home, a discussion about Guardsman filtration upgrades that keep the air cleaner between visits.
Our Guardsman Air Duct Cleaning Process
- 1
You call (469) 972-3151 and talk to a real person. We ask about your Guardsman system, the age of the home, whether you’ve had any renovations, and what prompted the call. Then we schedule an arrival window and stick to it.
- 2
We show up, walk the job, and write the price down. Before anything gets opened, you get a written price for the complete Guardsman duct cleaning. That price includes every vent, both trunks, the plenums, and the video inspection. If the scope needs to change, the new price is written and agreed to before we continue.
- 3
Video inspection first. We run a camera through the supply and return sides before cleaning so we both see what’s actually in there. You’d be surprised what’s been living in ducts that haven’t been touched since the Clinton administration.
- 4
Brush agitation, then negative-air extraction. Rotobrush rotary brush systems dislodge debris at the duct wall so it can’t stay stuck. Nikro negative-pressure units then pull that loosened material out of the system, while Abatement Technologies HEPA filtration keeps the particles from re-entering your living space. Negative-air extraction means the system is under suction the whole time, not blowing dust around.
- 5
Coil and plenum inspection. If your Guardsman coil has accumulated the film we described above, we address it as part of the full-system cleaning rather than leaving a source of new contamination upstream.
- 6
After photos and the 365-Day Done Right Promise in writing. We run the camera again so you can see the difference. Then we hand you the written guarantee: if the work falls short within a year, we return and make it right at no charge. That’s the Kingswell Way, and it’s not a verbal promise.
What Guardsman Air Duct Cleaning Costs in Los Angeles
| Scenario | Typical Price Range |
|---|---|
| Single-story home, 1 return, up to 8 supply vents | $450 - $600 |
| Two-story home, 2 returns, 10-15 supply vents | $600 - $800 |

What moves the price: the number of returns, how far the runs go, how long it’s been since the last cleaning, and whether your Guardsman coil needs attention. You’ll never get a per-vent price from us and then a different invoice at the end. One flat price per system, in writing, before work starts. Call (469) 972-3151 for an exact quote.

Why Los Angeles Homeowners Call Kestrel Air Duct Cleaning for Guardsman Work
Kestrel Air Duct Cleaning has been cleaning ducts in Los Angeles since 2004, and Dale Whitmore, our owner, has been at it for well over a decade. He trained at Los Angeles Trade-Technical College and has spent enough time inside Southern California ductwork to know exactly what our air does to a system. When a Guardsman unit shows up on a job ticket, our technicians know the equipment, the failure points, and what to check before the cleaning even starts.
Every job runs under the Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee on the work with a free return visit if it fails within the guarantee period. Our technicians are background-checked and uniformed, and they use Rotobrush, Nikro, and Abatement Technologies equipment, not a shop vac from a hardware store. We also work on Lennox, Trane, and Carrier systems, so if you have mixed equipment, one call handles the whole house. Clean ducts, straight answers, price upfront, that’s the whole deal.
FAQs
No, professional air duct cleaning does not void a Guardsman warranty. Guardsman warranties cover the equipment itself, not the ductwork, and cleaning the ducts does not involve modifying or opening the equipment. We use the same access points a Guardsman technician would use, and we document the process with before-and-after video. If you have a specific warranty concern, call (469) 972-3151 and we’ll walk through it with you before booking.
We run a video camera through your supply and return ducts before and after every job, and you keep the footage. You’ll see the dust, debris, and whatever else was in there before, and you’ll see the clean duct walls after. That, plus the written 365-Day Done Right Promise, is how you know. Call (469) 972-3151 to schedule, and the estimate is free.
The lowball quotes you see advertised usually cover a handful of vents and then find problems to charge for once the technician arrives. That’s the bait-and-switch pattern this industry is known for. We give one flat price per system in writing before any vent is touched, and that’s the price. Call (469) 972-3151 for a real number.
In Los Angeles, every three to five years is reasonable for most homes. Homes near busy roads, homes with pets, or homes that went through a renovation should lean toward the shorter end. If you have allergy sufferers in the house or you’ve never had the ducts cleaned, sooner is better. Call (469) 972-3151 and we’ll help you figure out where your system falls.
No. As an independent Guardsman service provider, we are not affiliated with or authorized by Guardsman. We service their equipment and know their systems well, but we operate independently under our own guarantee.
