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 Bonsall, CA
Air duct cleaning in Bonsall typically runs $350 – $650 for a whole-home system, with most jobs scheduled within a few days and completed in 2 – 4 hours. Hollis Air Duct Cleaning serves Bonsall’s semi-rural horse country, where homes on 1- to 5-acre lots deal with Santa Ana wind-driven dust, agricultural grit from surrounding groves, and wildfire ash that standard filters can’t stop. Our crews use Rotobrush rotary systems and Nikro negative-air machines to clear debris from long duct runs and multiple HVAC zones common in ranch-style and custom estate properties. Call (361) 326-5060 for a free written estimate before any work begins.
Why Bonsall Homes Are Different
Bonsall sits along the San Luis Rey River in a pocket of San Diego County that still feels like horse country. Properties sprawl across large lots with private wells and septic systems, and the housing stock is a mix of 1970s – 1990s ranch homes and newer custom estates. Many of those older homes still run original flex ductwork that has sagged, torn, or been chewed by rodents over decades of hot summers.
The Santa Ana winds hit Bonsall harder than coastal towns. From September through November, those dry easterlies funnel dust, pollen, and wildfire ash straight into attic vents and return grilles. After the 2017 Lilac Fire and smaller brush fires since, we’ve seen how fine ash bypasses standard filters and coats duct interiors. Homes with detached workshops or guest houses often have second HVAC systems, which means double the ductwork to maintain. The semi-arid climate also means cooling systems run hard from May through October, pulling in outdoor debris that settles in long duct runs.
Our Main Bonsall Services
Most Bonsall homeowners call us for one of these three jobs, each with its own local considerations:
Air Duct Cleaning in Bonsall
We clean the full supply and return system with a Rotobrush rotary brush and Nikro negative-air machine, pulling debris toward the vacuum so nothing escapes into living spaces. In Bonsall, we regularly find avocado pollen, fine riverbed dust, and wildfire ash packed into original 1980s flex duct. Homes with multiple additions often have patched-together duct runs that need extra attention at the joints. Every job gets a written price before we start and before-and-after photos of your own ducts. Air Duct Cleaning in Bonsall
Dryer Vent Cleaning in Bonsall
Dryer vent cleaning in Bonsall addresses longer vent runs common in ranch homes where the laundry room sits far from an exterior wall. Lint buildup in these extended ducts is a genuine fire hazard, especially in the dry season when static electricity runs high. We clear the full run from dryer to termination and check for proper airflow with a manometer. If the vent line is damaged or improperly routed, we’ll note it in writing before any repair work.

Duct Sealing in Bonsall
Duct sealing stops conditioned air from leaking into attics and crawl spaces through gaps at joints, seams, and rodent damage. In Bonsall’s older ranch homes, we often find 20 – 30% air loss before we start. We apply mastic sealant and mechanical fasteners, then verify results with a pressure test. Sealed ducts mean your HVAC doesn’t work as hard during those long cooling months, and less unfiltered air gets pulled in from the attic. Duct Sealing in Bonsall
