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.
Air Duct Cleaning Company in Castaic, CA
Air duct cleaning in Castaic typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. Hollis Air Duct Cleaning handles the dusty, wind-beaten duct systems that come with living at the western edge of the Santa Clarita Valley, where Mojave silt and wildfire ash create buildup that standard valley cleaning routines don’t address. We’re part of the Garrison Partners family, and every Castaic job gets a written price before we start, backed by our 365-Day Done Right Promise. Call (361) 326-5060 for a free estimate.
Why Castaic Homes Are Different
Castaic sits at the windy, dusty western gateway to the Santa Clarita Valley, and that position shapes every duct system we open here. The lake and surrounding canyons funnel intense seasonal winds straight through town, pulling fine Mojave silt into attic vents and return grilles year-round. After Santa Ana events or Angeles National Forest wildfires, we regularly find a distinct gray ash layer coating blower motors and return duct walls, a pattern our crews rarely see in coastal or deeper valley calls.
The housing stock splits three ways: 1980s – 2000s tract homes in Hasley Canyon and Hillcrest with original flexible ductwork in hot attics, newer tight construction near Castaic Lake, and scattered rural ranch properties with long duct runs to outbuildings. Those older flex ducts sag and collect debris in ways rigid metal doesn’t. Hot, dry summers bake attic systems while persistent wind drives pollen and smoke through every gap. There is almost no locally based duct-cleaning expertise here, which means most Castaic homeowners have been serviced by crews driving up from the basin without specific knowledge of these conditions.
Our Main Castaic Services
Most Castaic homeowners call us for one of three jobs. Each has its own page with full pricing and process details.
Air Duct Cleaning in Castaic
We clean the full supply and return system with a Rotobrush rotary brush and negative-air extraction from Nikro equipment, pulling out the fine silt and ash that settles in Castaic ductwork. The process covers all registers, the main trunk lines, and the air handler cabinet. In Hasley Canyon homes with sagging flex ducts, we flag structural issues before they tear. Air Duct Cleaning in Castaic covers full pricing and what to expect on arrival.

Dryer Vent Cleaning in Castaic
Lint buildup in dryer vents is a fire hazard anywhere, but Castaic’s dry heat and wind-blown debris accelerate it. We run a rotary brush through the full vent length to the exterior termination, then verify airflow with a meter. Extended runs in ranch properties or multi-story Hillcrest homes need extra attention. Dryer Vent Cleaning in Castaic has the full breakdown.

Duct Sealing in Castaic
Leaky ducts in Castaic’s hot attics waste cooled air and pull in dust through every gap. We apply duct sealing mastic and mechanical fasteners to joints and seams, then pressure-test the system to confirm the seal holds. Tight sealing matters especially in newer lake-area homes where builders prioritized envelope efficiency but missed duct continuity. Duct Sealing in Castaic explains the full process.

FAQs About Air Duct Cleaning Company in Castaic
No permit is required for standard duct cleaning or dryer vent cleaning in unincorporated Los Angeles County, which covers most of Castaic. Duct sealing that involves modifying the HVAC plenum or relocating registers may trigger permit requirements; we flag this during the estimate if it applies. Call (361) 326-5060 and we’ll check your specific address.
We prioritize calls when ash infiltration is suspected, but we do not promise same-day dispatch. Duct cleaning is a scheduled job, and post-event demand spikes. We add Castaic calls to the next available slot and advise homeowners to keep systems off until we arrive to prevent recirculation. Call (361) 326-5060 to get on the schedule.
