Pricing & Estimates
How much does air duct cleaning service cost?
Air duct cleaning in Los Angeles typically costs $350 to $700 for a standard single-family home with one HVAC system and 10 to 15 vents. Larger homes, two-story layouts, or properties running two separate systems usually fall in the $700 to $1,300 range because there’s more ductwork to reach and more returns to pull from. The final number depends on your vent count, the condition of the duct interior, and how accessible the runs are in your attic, crawlspace, or wall chases. What you’ll never get from us is a phone-quote that becomes a different price at your front door. The written price is in your hands before a single vent is touched.
| Service | Typical Price Range | What’s Included |
|---|---|---|
| Air duct cleaning – standard home (1 system, 10-15 vents) | $350 - $700 | Full supply and return cleaning, negative-air containment, brush agitation |
| Air duct cleaning – large home (2 systems or 15+ vents) | $700 - $1,300 | Same process across both systems, all accessible runs |
| Dryer vent cleaning – single-story | $150 - $260 | Full-length lint removal, exterior termination check |
| Dryer vent cleaning – multi-story or long run | $260 - $425 | Extended run cleaning, roof or second-floor termination access |

Do you offer free estimates?
Yes, estimates are free and so is the written price you’ll get before we begin. We’ll either ask you a handful of questions over the phone or, for larger or unusual systems, come out and look at the ductwork in person. Either way you get a firm number in writing – not a “starting at” figure, not a range that shifts once the truck is in your driveway. If the scope genuinely changes because we find something nobody could see from the outside, we stop, explain it, and get your approval before anything moves forward. That’s the Kingswell Guarantee at work: the price you’re given is the price you pay.
Is it cheaper to repair my ducts or replace them?
For most Los Angeles homes, cleaning is dramatically cheaper than replacement. A full duct cleaning runs $350 to $700. Replacing the ductwork in a typical attic system usually runs several thousand dollars, and most homes never need it. Replacement makes sense when the duct material itself is failing – crushed flex duct, disconnected runs, or ducts that are visibly torn or mold-saturated. Cleaning makes sense when the ducts are structurally sound but loaded with dust, debris, or lint. Our technicians will tell you honestly which situation you’re in before you spend a dollar. If your system needs work beyond cleaning, we’ll say so rather than sell you a cleaning that won’t fix it.
Do you charge extra for multiple HVAC systems?
Yes, and the reason is simple: every system has its own duct runs, its own return, and its own supply vents. A home with two HVAC systems effectively has two separate cleaning jobs happening under one roof. That said, we price it as one trip and one visit, so the second system is usually less than the first. The written price you receive will break out each system clearly – no blended number that hides the real cost of either one.
Service & Scheduling
Do you offer emergency air duct cleaning service?
Yes, we answer the phone 24/7 with a live person and can schedule emergency work when it’s genuinely needed. True air-duct emergencies are rare, but they do happen: water intrusion into a duct system after a roof leak, a rodent that’s gotten into the ductwork, or a sudden musty smell that points to something growing inside the runs. When that’s your situation, call (469) 972-3151 at any hour and you’ll reach a person, not a voicemail or an automated menu. We’ll figure out what’s actually urgent and get you on the schedule as fast as we can.
How fast can you respond?
Most non-emergency appointments are booked within a few days, and same-day or next-day slots open up regularly. We give you a defined arrival window when you book – a real two-hour block, not a vague “sometime Tuesday.” If our technician is running late, you get a call. That’s part of The Kingswell Way: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, come back if it fails. If you’re dealing with something urgent, call and tell us what’s going on. We’ll be straight with you about how fast we can be there.
How long does a typical air duct cleaning take?
A standard single-system home takes about 2 to 3 hours from setup to cleanup. Homes with two systems, or runs that are especially difficult to access, can take 4 to 5 hours. You don’t need to leave during the work, but you’ll want to plan for the noise and for the extension cords and equipment hoses that will be moving through the house. We lay down protective coverings and clean up after ourselves before we go.
Do I need to be home during the cleaning?
You don’t have to be home the entire time, but someone needs to let the technician in and walk the space once at the start and once at the end. We’ll show you what we’re doing, point out anything we find along the way, and do a final walkthrough with you so you can see the difference before we leave. If a homeowner has to step out, that’s fine – most people do – as long as we can reach you by phone if a question comes up.
What’s the step-by-step process you use?
Here’s exactly what happens on a Kestrel air duct cleaning, start to finish:
- Written price and walkthrough. Before any equipment comes off the truck, you have the price in writing, and we walk the home with you to identify every vent, return, and HVAC unit.
- Negative-air setup. We connect a Nikro negative-pressure unit to the system. In plain terms, that machine pulls air out of the ducts rather than blowing dust into your living room. Everything loosened during cleaning gets captured, not recirculated.
- Brush agitation. A Rotobrush rotary brush system is run through each duct run. The spinning brush scrubs dust and debris off the duct walls – the same way a bottle brush works on a glass – so the negative-air unit can pull it out from there.
- HEPA filtration. Abatement Technologies HEPA filtration traps fine particles – the stuff you can’t see – so the air around the work area stays clean while we work.
- Supply and return cleaning. Every accessible supply run, return run, register, and grille gets the same treatment. Nothing gets skipped because it’s hard to reach.
- Final walkthrough and documentation. We show you the system, confirm everything is reconnected and running, and hand over your written guarantee. The 365-Day Done Right Promise covers the work – if something’s not right within that window, we come back and fix it at no charge.
Licensing & Trust
Are you licensed and insured?
Yes, we’re state-licensed, fully insured, and every technician who steps into your home is background-checked and in uniform. We’ll show credentials on request – it’s your home, and you have every right to check. Most of the complaints homeowners bring to us aren’t about the work itself; they’re about contractors who couldn’t prove who they were, who skipped the paperwork, or who vanished after the invoice cleared. Kestrel was built as the answer to that. We’re part of the Kingswell family of companies, founded in 2004, and we’ve operated under the same written standard since day one.
Do you guarantee your work?
Yes, and it’s in writing on every single job: the 365-Day Done Right Promise. If the work falls short within 365 days, we return and make it right at no charge. That includes a free second visit if the original work fails – not a courtesy we extend at our discretion, a commitment that’s on paper. What qualifies? Any deficiency in the cleaning itself: a vent we missed, a run that’s still discharging dust after we left, a dryer vent that re-clogs because the cleaning didn’t reach the full-length run. To invoke it, call us, tell us what’s happening, and we’ll schedule the return visit. You don’t need to chase us, argue with a call center, or produce three forms of documentation. One phone call is enough.
How do I know the price won’t change when you arrive?
The written price you’re given is the price you pay, full stop. No door-step revisions, no “while we’re here we noticed” upsells, no fees tacked on after the work is done. If something genuinely different shows up that nobody could have known about – a disconnected duct buried behind a wall, for example – the technician stops, explains what they found, and gets your approval before anything changes. There’s no manufactured urgency and no pressure. You decide; we work.
What payment methods do you accept?
We accept major credit and debit cards, and payment is collected after the work is complete, not before. You’ll never be asked to pay up front, and you’ll never get a cash-only request at the door – that’s a red flag on any service call, and it’s not how we operate. If you have a question about a specific payment situation, call us before your appointment and we’ll sort it out.
Who runs Kestrel Air Duct Cleaning?
Kestrel is led by Dale Whitmore and is part of the Kingswell family of companies, founded in 2004. Each location is independently owned and operated under the Kingswell Guarantee, which means the person responsible for the work in your home is also the person accountable if something goes wrong. The Kingswell Way isn’t a slogan we trot out at sales time – it’s the actual code our technicians follow on every visit: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, come back if it fails.
Specific Services
Do you handle air duct cleaning?
Yes, it’s one of our two core services and our namesake. Air duct cleaning removes the accumulated dust, debris, pet dander, and construction dust that builds up inside your supply and return duct runs over the years. In Los Angeles specifically, we see a few patterns worth knowing about. Homes near the hills and canyons pull in fine wildfire ash and soot through the HVAC system, especially after Santa Ana wind events – it settles inside the ducts and then gets blown back through the house every time the system runs. Older homes in the flats with original galvanized ducts often have heavily rusted interiors that trap particulate. And homes with recent renovations frequently have drywall dust compacted into the return runs. A proper cleaning with negative-air extraction and rotary brush agitation addresses all of it. You can read the full detail on our Air Duct Cleaning in Los Angeles page.
Do you handle dryer vent cleaning?
Yes, dryer vent cleaning is our second core service, and it’s the one we get called about most often for repeat problems. A clogged dryer vent doesn’t just slow your drying time – it’s a fire risk, and it’s the leading cause of dryer fires nationwide. In Los Angeles, we see two recurring culprits. First, the long horizontal runs common in single-story homes along the valley and near the coast, where lint settles in the middle of the run and never reaches the exterior termination. Second, roof-terminated dryer vents on multi-story homes, which are almost impossible for a homeowner to reach and inspect. A “cleaning” that only vacuums the lint trap area is a waste of money – the full-length run and the exterior termination cap are where the real blockage lives. We clean the whole path, top to bottom.
Do you handle HVAC cleaning?
We clean the duct system connected to your HVAC equipment, but we don’t service the mechanical unit itself. In plain terms: we clean the ducts, returns, and registers that carry air to and from your furnace or air handler. If your system needs refrigerant work, a compressor repair, or a full tune-up on the mechanical components, that’s a separate job for an HVAC technician, and we’ll tell you that straight rather than bill you for something we don’t do. Plenty of homeowners call us thinking they have an HVAC problem when what they actually have is a dirty duct problem – reduced airflow, weak output at certain vents, or a dusty smell when the system kicks on. Those are all duct-side issues, and they’re exactly what we fix.
Do you handle duct repair and sealing?
We don’t perform duct repair or sealing as a standalone service – our work is cleaning and dryer vent service. If our technician finds a disconnected run, crushed flex duct, or a damaged joint during a cleaning, we document it and tell you what we see. You decide what to do with that information; we don’t push you into repair work we don’t do. That’s a deliberate choice. We’d rather be excellent at two things than mediocre at six.
Do you clean dryer vents on roofs and in hard-to-reach places?
Yes. Roof-terminated vents and second-story exterior terminations are common in Los Angeles and are exactly the runs that get skipped by companies who only work at ground level. If your dryer vent exits through the roof, we get up there, clean the full run from the appliance through the termination, and check that the cap and damper are working properly. If your run is especially long or has multiple bends, that’s fine – it just takes more time and the right equipment, and we have it. Lint trap bypass – lint that slips past the trap and into the duct – is the underlying cause of most dryer vent clogs, and cleaning the full length is the only way to actually solve it.
What kind of equipment do you use?
We use professional-grade equipment, not box-store shop vacs. Rotobrush rotary brush systems agitate the duct walls so debris releases rather than just getting surface-vacuumed. Nikro negative-pressure units pull the loosened contaminants out of the system entirely, rather than stirring them into the air. Abatement Technologies HEPA filtration captures the fine particles during the work so your living space stays clean while we operate. For homeowners who want to maintain cleaner air between service visits, we can also help you choose filtration and indoor-air-quality products from Honeywell, Aprilaire, or Guardsman. We don’t install them, but we’re happy to point you toward the right fit.
What areas do you serve?
Kestrel Air Duct Cleaning serves Los Angeles and the surrounding neighborhoods and communities. Each location is independently owned and operated under the Kingswell Guarantee, and our service area is built around getting to your door within a reasonable arrival window. If you’re not sure whether we cover your address, call us at (469) 972-3151 – a real person will pick up and give you a straight answer in under a minute. We don’t route you through a call center or leave you waiting on a callback.
How often should I get my air ducts and dryer vent cleaned?
Most homes should have air ducts cleaned every 3 to 5 years, and dryer vents cleaned every 6 to 12 months. A few factors push that timeline shorter: pets in the home, recent renovations, wildfire smoke exposure, or a household member with allergies or asthma. For dryer vents specifically, annual cleaning is the safe standard – lint accumulates continuously, and the risk profile of a clogged vent is severe enough that annual service is the responsible choice. If you’re not sure where your home falls on that spectrum, call us and describe your situation. We’ll tell you honestly whether you need us now or whether you can wait another year.
What happens if the dryer vent clogs again after cleaning?
If a dryer vent we cleaned re-clogs within 365 days, that’s covered under the 365-Day Done Right Promise and we come back at no charge. Typically a re-clog means the original work didn’t reach the full length of the run, or the exterior termination wasn’t properly cleared. Both are on us to fix, and we do. What isn’t covered is a new blockage caused by something we didn’t touch – a bird that built a nest in the termination cap three months after we left, for example. In that case we’ll still come out; we’ll just be honest about what caused it.
How do I book an appointment?
Call (469) 972-3151 any time, day or night, and a real person will answer. We’ll ask a few quick questions about your home – number of systems, approximate vent count, whether the dryer vent is the priority – and give you a written price and a two-hour arrival window. No deposit required, no commitment until you say yes. If you’d rather read more before you call, start with our home page to see how we operate, then call when you’re ready.
What should I expect from the technician who shows up?
Expect a background-checked, uniformed technician who introduces himself, walks the home with you, and lays out protective coverings before any work begins. He’ll show you the equipment, explain what each piece does in plain language, and tell you what he’s seeing inside the ducts. When the work is done, he’ll walk the system with you, confirm everything is reconnected and running, and hand you the written guarantee. If something doesn’t look right to you at any point, say so. The Kingswell Way means we leave the place cleaner than we found it and put the guarantee in writing – that’s the standard, and if we miss it, we come back.
Do you use any kind of chemical treatment in the ducts?
No, our standard service is mechanical cleaning – brush agitation and negative-air extraction – not chemical application. Mechanical cleaning removes what’s actually inside the ducts. Products that “fog” or “sanitize” a duct system without first removing the debris underneath it don’t accomplish much, and we’d rather not charge for something that doesn’t solve the problem. If you have a specific concern – odor, microbial growth, or an allergy situation – call us and describe it. We’ll tell you honestly whether mechanical cleaning is the right answer or whether you need a different kind of specialist.
Can cleaning my ducts actually lower my energy bills?
It can, when the ducts are heavily loaded. When supply and return runs are restricted by debris buildup, your HVAC system has to work harder to move the same volume of air, and that shows up on your bill. Cleaning restores airflow, and in most cases homeowners see better system performance and more consistent temperatures room to room. We won’t promise a specific dollar savings – that depends on your system, your utility rates, and how badly the ducts were restricted to begin with. What we’ll promise is the cleaning itself, in writing, with the 365-Day Done Right Promise behind it. If it’s not done right, we make it right.
