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.

Why Kestrel Air Duct Cleaning Is Lafayette’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Lafayette by showing up when we say we will and putting our promises on paper. The Kingswell Guarantee, which governs every visit since our founding in 2004, means four things: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if the work fails within the guarantee period. No exceptions.
Our technicians are background-checked and uniformed, and they know Lafayette’s housing stock. Most homes here went up between the mid-1950s and mid-1970s with original sheet-metal ductwork featuring unsealed joints, or later flex duct routed through attics that hit 140°F in summer. That local knowledge changes how we approach the job. We don’t guess. We inspect first.

Air Duct Cleaning Services in Lafayette
Air Duct Cleaning Services in Lafayette address a specific set of conditions you won’t find in cooler, coastal Bay Area cities. Our process begins with a video inspection of your supply and return trunks, then moves to source removal using Rotobrush rotary brush agitation, which physically dislodges debris caked on duct walls, paired with Nikro negative-air extraction that pulls loosened contaminants out of your system entirely. Abatement Technologies HEPA filtration runs continuously during cleaning to keep particles out of your living space. A typical residential full-system cleaning in Lafayette runs $550-$850, with smaller homes or partial cleanings starting around $450.
Residential Duct Cleaning
Most Lafayette homes we service are ranch-style or split-level builds from the post-war era, with ductwork that has never been properly cleaned or sealed. We clean supply ducts, return ducts, and the air handler cabinet as one integrated system, because treating them separately leaves contamination behind.
Commercial Duct Cleaning
Small commercial properties along Mt. Diablo Boulevard and in the downtown corridor face the same smoke and dust loading as residences, often with more complex zoning and longer duct runs. We scale our equipment to the building and provide the same written price guarantee.

HVAC Duct Cleaning in Lafayette
HVAC Duct Cleaning in Lafayette requires attention to conditions that actively damage ductwork. The inland valley location here produces summer highs above 95-100°F, driving attic temperatures to 140°F or higher. That heat accelerates flex-duct inner liner breakdown, causing fiberglass shedding and partial collapse that simple dust removal won’t fix. We see this constantly in hillside homes along Happy Valley Road and upper Reliez Valley Road, where attics bake and liners degrade far faster than in Orinda’s cooler, shadier canyons. A complete HVAC duct cleaning in Lafayette typically costs $550-$850, with video inspection included to identify liner damage before cleaning begins.
Video Inspection
We run a camera through your supply and return trunks before quoting. This shows you, and us, whether you’re dealing with standard dust accumulation, active liner shedding, or collapsed flex sections that need replacement before cleaning is even worthwhile.
Full System Cleaning
Supply duct cleaning alone misses half the problem. Return ducts pull air, and contaminants, back to the air handler. We clean both sides, plus the cabinet and coils, as a single system. Anything less is incomplete.
Trusted Brands We Service in Lafayette
We clean ductwork connected to every major HVAC brand, and we stock Honeywell, Aprilaire, and Guardsman filtration products for Lafayette homeowners who want to maintain cleaner air between service visits. Our technicians carry common filter sizes and can upgrade your return-air filtration on the same visit if your system allows. For properties near Briones Regional Park or along the rural edges of Reliez Valley, where dust and pollen loading is heavier, a properly sized Aprilaire media filter can extend the interval between full cleanings by capturing more particulate before it enters your ductwork.
Common Air Duct Cleaning Problems We See in Lafayette Homes
- Flex-duct liner collapse from extreme attic heat. Lafayette’s 140°F+ attic temperatures cook flex-duct inner liners until they crack, shed fiberglass, or collapse entirely. We find this in hillside homes with long attic runs, and it requires replacement, not just cleaning.
- Wildfire smoke infiltration during Diablo wind events. September through November, hot offshore flows push concentrated smoke and fine dust directly into HVAC intakes. Systems running for cooling pull those particulates deep into ductwork, creating acute contamination on top of baseline dust.
- Unsealed joints in original sheet-metal ductwork. Lafayette’s mid-century housing stock often has metal ducts with gaps at seams and connections. These leak conditioned air into attics and pull attic dust, insulation particles, and occasional rodent debris into the supply stream.
- Overlooked dryer vent lint buildup on rural properties. Longer vent runs to outbuildings or additions, common on Lafayette’s larger lots and rural edges, create extended lint pathways that standard cleanings miss. This is a genuine fire hazard and a major efficiency loss.
Pricing for Air Duct Cleaning in Lafayette, CA
Most Lafayette homes run between $550 and $700 for a complete residential air duct cleaning. Smaller systems or partial cleanings (supply only, or limited vent count) start around $450. Larger homes with extensive flex-duct replacement needs, or commercial properties with complex zoning, can reach $850 or above. We give one flat price per system, agreed in writing before work starts. No per-vent pricing. No door-step revisions. The price we quote is the price you pay. Factors that affect your specific cost include duct accessibility, the presence of damaged liners requiring replacement, and whether video inspection reveals contamination that needs extended cleaning time. Estimates are free. Call (469) 972-3151.
We Also Serve Cities Near Lafayette
Our crews regularly work in Walnut Creek, Orinda, Moraga, and Pleasant Hill, but Lafayette properties present unique challenges we don’t see elsewhere. The combination of extreme attic heat, wildland-urban interface smoke exposure, and rural dust sources from open land and unpaved roads means Lafayette homeowners benefit from a shorter cleaning interval and specific attention to flex-duct integrity. If you’re in the surrounding area and need service, our Air Duct Cleaning team covers the full Lamorinda valley and central Contra Costa County.

FAQs About Air Duct Cleaning in Lafayette
Every 2-3 years for most Lafayette homes, and every 1-2 years if you’re on open land near Briones Regional Park or experienced a significant Diablo wind smoke event. The rural dust loading and wildfire smoke infiltration here accelerate contamination compared to coastal Bay Area cities. Call (469) 972-3151 to schedule a free video inspection and we’ll tell you where your system stands.
Unpaved roads, agricultural activity, and the wildland-urban interface around Lafayette generate more coarse and fine particulate than suburban grid neighborhoods. Your HVAC system pulls that dust in through outdoor air intakes and return leaks, then recirculates it until it deposits in ductwork or gets filtered out. Sealing duct joints and upgrading filtration helps, but periodic source removal cleaning is necessary. Call (469) 972-3151 for an estimate.
Yes. Sustained extreme heat degrades flex-duct inner liners, causing them to crack, shed fiberglass particles into your airstream, and eventually collapse. We see this routinely in Lafayette hillside homes where attic ventilation is minimal and summer temperatures peak higher than in cooler nearby cities. Video inspection reveals the condition before we clean. Call (469) 972-3151 to book an inspection.
Replace your HVAC filter immediately, then schedule a duct inspection within two weeks if your system was running during the event. Smoke particulates are small enough to penetrate deep into ductwork, and standard filters won’t catch the finest fraction. We clean fresh-air intakes and economizers as part of our service, not just the ducts themselves. Call (469) 972-3151 to get on the schedule.
Yes. We service detached garages, guest houses, pool equipment rooms, and other outbuildings with ducted systems or dryer vent runs. These longer pathways are often overlooked by standard contractors, and they accumulate lint and dust at rates that surprise homeowners. We price these as separate systems with the same written upfront guarantee. Call (469) 972-3151 for a custom quote.
We serviced a ranch-style home off Happy Valley Road where the homeowner complained of fiberglass particles on furniture. Camera inspection revealed a collapsed flex-duct liner in the attic, victim of 140°F+ summer heat. Using negative pressure and Rotobrush agitation tools, we performed source removal on the supply and return ducts, then replaced the failed liner and sealed the air handler cabinet. The particle complaint ended after the first post-service cycle.
Lafayette sits at the wildland-urban interface directly adjacent to Briones Regional Park, and its position in the inland Lamorinda valley means HVAC systems run continuously during triple-digit summer heat. When fall Diablo wind events push wildfire smoke through the area, those running systems actively pull fine particulates deep into ductwork in a way that cooler, coastal Bay Area cities like Berkeley or Oakland never experience. This recurring smoke-infiltration cycle, compounded by years of heavy AC use, makes post-smoke-season duct cleaning a genuinely critical service for Lafayette homeowners, not a cosmetic luxury.
