The Kestrel Air Duct San Diego Guarantee
We’ve been cleaning air ducts in San Diego since 2004, and we’ve always operated the same way: we tell you the price before we start, we show up when we said we would, we leave your home cleaner than we found it, and we put the guarantee in writing. Every single visit runs under the Kingswell Guarantee, a written standard that’s been applied to every job since the first one Dale Whitmore ran back in 2004. For a San Diego homeowner, that means you never wonder what the final bill will be, never chase a technician for a missed window, and never worry that a problem discovered three months later is somehow your problem to solve alone. The 365-Day Done Right Promise covers it: if the work falls short within a year, we return and make it right at no charge. Written down. On your invoice. Before we touch a single vent.
Dale Whitmore still runs Kestrel Air Duct San Diego the same way he did on day one, because a guarantee is only as good as the person standing behind it. Call (619) 695-0424 and you’ll get a live person, not a phone tree. That matters when you’re asking about a guarantee, because you should be able to talk to a human who can actually answer the question.
What’s Covered
Here’s the specific list of what our written guarantee covers on every air duct cleaning and dryer vent cleaning job in San Diego:
- Workmanship on the full system. If any part of the cleaning we performed doesn’t hold up, we return and re-clean the affected section at no charge within the 365-day guarantee period.
- The written price, always. The price you approve before work begins is the price you pay. No per-vent add-ons, no surprise fees when the technician finds a heavily soiled return, no door-step revisions.
- On-time arrival within a defined window. We give you a specific arrival window before we come out, and we show up inside it. If we miss it, that falls under the guarantee. It’s not a courtesy. It’s written down.
- Clean job site, every time. Floors protected, furniture moved carefully, no debris left behind. When we leave, your home is cleaner than when we arrived. If we miss something, you call and we fix it.
- Equipment and material handling. Our Rotobrush, Nikro, and Abatement Technologies equipment is professional-grade, and we stand behind the work it does. If a component we touched fails because of something we did, the Kingswell Guarantee covers the return visit.
- The guarantee itself, in writing. You get a written copy of the 365-Day Done Right Promise on your invoice. If the work falls short within that year, Kestrel returns and makes it right at no charge.
Dale’s rule from the start has been simple: say the price, show up in the window, leave the place cleaner, put the guarantee in writing, and come back if it fails. That’s The Kingswell Way, and it’s the code every Kestrel technician follows on every San Diego job site.

Our Satisfaction Promise
Here’s how it works if you’re not satisfied with an air duct cleaning or dryer vent cleaning from Kestrel Air Duct San Diego. You call (619) 695-0424 and tell us what’s wrong. We don’t argue with you or make you justify the complaint. We schedule a return visit at no charge, send a technician back out, and we re-do the work that didn’t meet the standard. The 365-Day Done Right Promise covers the first year after your cleaning, and it’s documented in writing on your invoice. You don’t need to keep a receipt buried in a drawer. You don’t need to prove the original tech did something wrong. If you say the work fell short, we come back and make it right.
Most of the time, a homeowner’s concern is something straightforward: a register they think we missed, a section of duct they want re-checked, a dryer vent that still feels restricted. We’ve had calls like that from Clairemont to Chula Vista, and every one of them got a free return visit. The guarantee is not a promotional offer or a customer-service script. It’s a standing commitment printed on every invoice since 2004, and the free second visit is included in writing, not extended at the company’s discretion. If a return visit doesn’t resolve it, we’ll keep working through it until the job is done to the written standard. That’s what Dale means when he says the guarantee actually guarantees something.

AfterLicensed & Insured Backing
Every Kestrel Air Duct San Diego technician is licensed, insured, and bonded, and every one of them is background-checked before they ever walk into a San Diego home. That’s the quiet part of the guarantee that most people don’t think about until something goes wrong. A written promise matters because the company behind it is real: incorporated, insured, and accountable. If our equipment damages your drywall, our insurance covers it. If a technician gets hurt in your crawl space, our workers’ comp covers it, not your homeowner’s policy. You should ask any duct cleaning company you’re considering to show proof of insurance before they step through your door. We’ll show you ours without hesitation. Between the licensing, the insurance, and the Kingswell Guarantee in writing, you’re covered by a real company with a real address and a real owner named Dale Whitmore, not a guy with a shop vac and a Craigslist ad.
Why the Guarantee Is Written Down
Most guarantees in the air duct cleaning industry are verbal. That’s not a guarantee. That’s a sales tactic. A real guarantee exists on paper, with specific terms, a defined coverage period, and a clear process for invoking it. The Kingswell Guarantee has been the same written standard since 2004, applied to every job from the first one. The 365-Day Done Right Promise is printed on your invoice. The free return visit if the work fails is included in writing. The arrival window is on the appointment confirmation. The price is on the work order before a single vent is opened.
When a San Diego homeowner asks us what we stand behind, Dale’s answer is the same one he’s given since 2004: we stand behind the written guarantee, and we’ve never had to hide behind it.
