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.
The Kestrel Air Duct Los Angeles Guarantee
Every job we take in Los Angeles goes under the Kingswell Guarantee, and that guarantee has been the same written standard since 2004. Before any work begins, you get a written price. You get a defined arrival window. We leave the job site cleaner than we found it. And you get the guarantee in writing, not as a verbal promise that evaporates the moment our van pulls away. If the work falls short within the guarantee period, we return and make it right at no charge. That is the whole arrangement, stated plainly, before a single vent is touched.
What’s Covered
- Written price before work begins. The number on the quote is the number on the invoice, always, on every visit, with no exceptions.
- Defined arrival window. We give you a window, we show up in that window, and if we’re running late you hear from a live person, not a text bot.
- Clean job site. Drop cloths at the entry, shoe covers on, and a sweep-up before we leave. The Kingswell Way says leave the place cleaner, and we hold our techs to it.
- Background-checked, uniformed technicians. The person in your home is someone we vetted, trained, and can identify by name.
- Professional-grade equipment, used properly. Rotobrush rotary brush systems dislodge debris at the duct wall. Nikro negative-pressure units pull contaminants out. Abatement Technologies HEPA filtration keeps loosened particles out of the living space while we work. No box-store shop vacs, no shortcuts.
- Honest pricing with no door-step revisions. The price you approved is the price you pay. If we find something unexpected, we stop and talk to you before touching it.
- 365-Day Done Right Promise. If the work falls short within the guarantee period, Kestrel returns and makes it right at no charge.
- Free second visit if the work fails. That’s included in writing, not a courtesy extended at our discretion.

Our Satisfaction Promise
Here is the process, step by step, so there is no ambiguity about how we handle a problem. You call us at (213) 733-0665. A live person answers, any time of day, because that is how we have operated since the beginning. You tell us what fell short. We review the job record, including the written guarantee that went with the original work. If the issue falls within the 365-Day Done Right Promise, we schedule a return visit at no charge. A technician comes back, addresses the specific problem you identified, and leaves you with the same written guarantee on the correction. There is no re-quoting, no re-negotiating, no “that’s a different service” runaround. The guarantee is per job, in writing, and our name is on it. If we made the mistake, we fix the mistake. That is the entire policy. Dale Whitmore signs his name to every job we book in Los Angeles, and he has been doing that since 2004.
Licensed & Insured Backing
Every guarantee is only as good as the company standing behind it, which is why we carry the credentials that matter before we ever walk through your door. Kestrel Air Duct Los Angeles is licensed and insured, so the written promise comes with real standing behind it. Insurance protects your home if something goes wrong on the job. Licensing means we answer to the standards of the city and county we work in. Together they mean this: the Kingswell Guarantee is not a slogan. It is an obligation with consequences if we fail to honor it. A company working without insurance or proper licensing cannot make that same claim, and you should always ask before booking anyone.

AfterHow the 365-Day Done Right Promise Works
The promise is simple, but we have found that homeowners want the details spelled out. Here they are. The guarantee period is 365 days from the date of the completed job. The promise covers the workmanship we performed: the cleaning itself, the condition we left the ducts in, and the job site standards we committed to. If anything we touched falls short within that year, we come back and fix it at no charge. What does invoking it require from you? A phone call to (213) 733-0665. That’s it. No claim forms, no fine print hoops, no arbitration clause buried in a contract. You tell us what went wrong, we pull the written record, and if it is within the guarantee, we schedule the return. The free second visit is written into the original job documentation, not something you have to negotiate for when a problem arises.
Why We Put It in Writing
The air duct cleaning trade has a trust problem, and we know it. Homeowners get a low teaser price, then a tech shows up and the invoice balloons before a single vent is touched. That is not us. The Kingswell Guarantee exists because Dale Whitmore got tired of watching that pattern play out across Los Angeles homes. A written price, a defined window, a clean site, and a written guarantee are not gestures. They are the operating system. Since 2004, every job under the Kingswell name has run on these four promises, and every Kestrel tech knows they are measured against them on every visit. The Kingswell Way values code governs the day-to-day: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, come back if it fails. There is no exception clause for busy weeks or bad weather. Those five rules are the job.
What the Guarantee Does Not Cover
Being straight about limits is part of the guarantee. We do not cover conditions that existed before our work and were unrelated to the cleaning. We do not cover damage from pests, water intrusion, or ductwork that was already failing due to age or poor installation. If we spot asbestos, mold, or any condition that requires a specialist, we stop and tell you. We do not pretend to be a mold remediation company or an insulation installer. Kestrel Air Duct Los Angeles performs two services: air duct cleaning and dryer vent cleaning. That focus is intentional. If a problem falls outside those two services, we tell you plainly and point you toward the right trade. A guarantee that overpromises is not a guarantee. It is a sales tactic.
Frequently Asked Questions
Call (213) 733-0665. A live person answers, you explain the issue, and we check it against the written guarantee. If it falls within the 365-Day Done Right Promise, we schedule a return visit at no charge. No arguing, no re-quoting.
One phone call to (213) 733-0665. That is the entire process. You tell us what fell short, we pull the job record, and if the workmanship is within the guarantee period and the problem is something we performed, we return and fix it. The free return visit is already in your written guarantee, not a favor you need to ask for.
Yes. The Kingswell Way explicitly says leave the place cleaner, which is part of the written guarantee on every job. Drop cloths, shoe covers, and a sweep-up are not optional extras. If our techs leave a mess, that is a guarantee issue, and we come back and make it right.
It means two things. Insurance covers your home if something goes wrong during the job. Licensing means we answer to local standards and can be held accountable. A company without either cannot make the same standing claim, and you should treat that as a red flag when comparing air duct cleaners in Los Angeles.
A verbal promise is worth exactly what it is printed on: nothing. Ours is printed. The written price, the written guarantee, the free second visit, all documented on the job before work starts. If we fail to honor it, you have something to hold. That is the difference between a company that stands behind its work and one that hopes you never call back.
Call (213) 733-0665 for a written quote. The price you see is the price you pay, and the guarantee comes with it in writing.
