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.

AfterAir Duct Cleaning Company in Walnut, CA
Kestrel Air Duct Cleaning provides whole-system air duct and dryer vent cleaning for Walnut homeowners. Most Walnut jobs run between $285 and $525 for a full duct system, and between $110 and $185 for a dryer vent, depending on home size, duct condition, and how many years it’s been since the last cleaning. Walnut’s housing stock and hillside location mean our technicians see specific problems here more than almost anywhere else in the San Gabriel Valley. If you need an exact number, call (469) 972-3151 and we’ll give you a written price before any work begins.
Why Walnut Homes Are Different
Walnut sits at the mouth of the Pomona Valley wind corridor. When Santa Ana events push through, they carry desert dust and, increasingly, wildfire ash from the San Jose Hills and foothill canyons directly into residential HVAC intakes. This particulate load lands on neighborhoods across the city, from the hillside-adjacent tracts near Snow Creek and Creekside to the flatter streets around Suzanne and Lemon. And because most of Walnut’s housing stock dates to the late 1970s through early 1990s, that dust is settling into ductwork that is now 35 to 45 years old.
The original fiberglass duct board and first-generation flex duct installed when these two-story stucco tract homes were built has quietly outlived its design life. Our crew sees collapsed inner liners, separated joints, and heavy settled debris in Walnut more often than in neighboring cities. The reason is attic heat. Walnut’s south-facing, tile-roofed 1980s homes routinely hit 140°F or higher in their attics during summer. Those repeated thermal expansion cycles degrade the plastic inner liner of flex duct long before the outer jacket shows any visible damage. A homeowner who glances into the attic sees ductwork that looks intact; the actual airflow path inside may have narrowed to half its original diameter. Understanding that specific condition is what makes a Walnut job different.
Our Main Walnut Services
These are the two services we handle for Walnut homeowners. Each has its own Walnut page with full pricing and local details.
Air Duct Cleaning in Walnut
Air duct cleaning means removing the settled dust, pet dander, construction debris, and in Walnut’s case, wind-driven ash that collects inside supply and return ducts over years. We use a Rotobrush rotary brush system to dislodge debris at the duct wall, then a Nikro negative-pressure unit pulls it out at the source so it never enters your living room. For homes near the San Jose Hills, we often find a finer gray ash settled along the bottom of return ducts after fire season. That material compacts over time and reduces airflow, forcing your HVAC system to run longer cycles. See Air Duct Cleaning in Walnut for full scope details and exact cost ranges.
Dryer Vent Cleaning in Walnut
Dryer vent cleaning removes the lint that accumulates inside the vent run from your dryer to the exterior exit point. Walnut’s two-story homes often have long vertical vent runs through an interior wall, which catch more lint than a short horizontal run. When that vent clogs, drying times climb and the risk of a lint-fueled fire rises. Our technicians use rotary brush agitation to break up compacted lint, then apply negative-pressure extraction to remove it completely. Before we touch the vent, we test airflow so you have a baseline number. We clean the entire run in both directions, not just the first few feet, because the clog is rarely where the lint trap is. See Dryer Vent Cleaning in Walnut for full details.

Pricing for Air Duct Cleaning Company in Walnut, CA
| Service | Typical range in Walnut |
|---|---|
| Whole-home air duct cleaning | $285 - $410 |
| Two-system homes or homes over ~2,800 sq ft | $410 - $525 |
| Return register and supply vent cleaning (included) | Included |

Two main things push a Walnut job toward the higher end of these ranges. First, homes with two separate HVAC systems – common in the larger two-story tracts – have more duct runs and more returns. Second, ducts that have not been cleaned in 10 or more years take longer to do properly because the debris has compacted against the duct walls and must be dislodged rather than vacuumed loose. Whatever the condition, you get the same written price before our technician touches a vent. No percentage added at the door, no line-item surprises.

FAQs About Air Duct Cleaning Company in Walnut
Most whole-home duct cleanings in Walnut take 3 to 5 hours, depending on home size and how many years’ worth of debris has settled inside. Larger two-story homes with two HVAC systems run toward the upper end. Your technician will confirm the expected window when you book.

What Walnut Customers Say
"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
