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.

AfterFast, Reliable Air Duct Cleaning Across Poway
Air duct cleaning in Poway typically runs $350 – $650 for a full residential system, and every Hollis job starts with a written price before we touch anything.

Call (361) 326-5060 for a free estimate.
Poway’s inland location at the base of the Poway Grade creates a duct environment unlike coastal North County. Santa Ana winds funnel smoke and ash from surrounding canyons straight into residential HVAC systems, while attic temperatures that regularly exceed 140°F cook original 1970s – 1990s flex runs until they sag, crack, and separate. We’ve been cleaning and repairing ducts here since 2004, and we’ve learned that a Poway clean is almost always decontamination plus Duct Sealing in Poway, not just dust removal.

Vent Cleaning in Poway
Vent Cleaning in Poway starts with understanding what “vent” actually means in your house: the supply registers that blow conditioned air into rooms, and the return grilles that pull air back to the handler. In Poway, these openings are where you’ll first notice smoke smell after a Santa Ana event, because ash and charred debris collect at the grille face and inside the boot behind the wall. We remove each register, agitate the boot and first few feet of branch line with rotary brushes, and capture debris under negative pressure so nothing drifts into your living space.
A typical vent cleaning as part of a full system service in Poway runs $350 – $650 for the complete job. Standalone vent cleaning for a limited scope starts around $200. We don’t price per vent. One flat price per system, agreed before we start.
Supply Vent Decontamination
Supply vents in Poway homes often hide a second problem behind the grille: disconnected flex runs that have dropped into the attic after years of heat cycling. We run a camera inspection on every supply branch we clean, so we catch the sagging run before we seal the register back up. If we find a failure, we show you the image and quote the repair in writing.
Return Grille Smoke Removal
Return grilles sit closest to the air handler and pull the highest volume of air, which means they collect the most ash during fire season. In Poway, we regularly find black residue baked onto the grille fins and inside the return box. We source-remove this material with HEPA-contained agitation, then sanitize the surface so the smoke smell doesn’t return the first time you run the system.
Air Duct Repair in Poway
Air Duct Repair in Poway is not an upsell. It’s what we find when we open a system built in 1978, 1985, or 1992. Original rigid fiberglass duct board and flex runs in unconditioned Poway attics have been baking past 140°F for decades. The material sags, cracks at joints, and separates entirely. A cleaning without leak testing just pushes dust through the gaps and calls it done. We don’t work that way.
Duct repair in Poway typically adds $150 – $400 to a cleaning visit, depending on how many branches need reconnection, mastic sealing, or replacement flex. We photograph everything before and after. You see what we saw.
Leak Testing and Re-Sealing
After we clean, we pressure-test the system to find the gaps that Poway attic heat has opened over thirty-plus years. We seal joints with duct mastic rated for high-temperature cycling, not tape that will dry and fall off in the next heat wave. The goal is a system that moves air through the rooms, not into the insulation.
Disconnected Branch Reconnection
At a 1978 ranch house off Espola Road in Green Valley, our tech pulled black ash and charred debris out of the return trunk under negative pressure, then ran a camera down the original flex runs and found two crushed and disconnected branches sagging in an attic that had baked past 140°F for decades. We source-removed the debris with agitation tools and HEPA filtration, reconnected and re-sealed the failed runs, and the homeowner noticed the smoke smell at the return grille was finally gone. This is standard work for us in Poway. We bring the camera on every job.
Trusted Brands We Service in Poway
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for contained debris removal, and HEPA filtration from Abatement Technologies and Guardsman that captures particles down to 0.3 microns. We also stock duct sealing products and replacement flex in common Poway sizes, so most repairs finish same visit without waiting on parts. For homeowners upgrading filtration after a clean, we carry Honeywell and Aprilaire media cabinets that drop into standard return plenums. Everything we use is professional-grade, not hardware-store gear, and we explain what each tool does before we start it up.
Common Air Duct Cleaning Problems We See in Poway Homes
- Smoke and ash loading in return systems. Poway’s position below the Poway Grade funnels Santa Ana winds and wildfire smoke from surrounding canyons directly into residential HVAC systems. After events like the 2003 Cedar Fire or 2007 Witch Creek Fire, we routinely pull black ash and charred debris out of return ducts in homes miles from the burn zone. A routine dust-only clean leaves this residue behind.
- Heat-cooked flex duct in unconditioned attics. Poway’s hot inland summers push attic temperatures above 140°F, which degrades original 1970s – 1990s flex runs until they sag, crack, and collect dust at joints. Almost every system we open in Old Poway or Green Valley needs re-sealing at minimum.
- Disconnected branches hidden behind registers. Decades of vibration and thermal expansion separate flex from boots inside wall chases. Without camera inspection, the broken branch keeps pulling attic air and chaparral dust straight into the supply side. We find this on roughly half the 1980s tract homes we service.
- Garage-adjacent combustion air intake contamination. Many Poway homes draw combustion air and return air from garages that sit close to open chaparral. During wind events, this pulls smoke, pollen, and dust directly into the system. Proper sealing and filtration upgrades are the fix, not just cleaning.

FAQs About Air Duct Cleaning in Poway
Because Santa Ana winds carry ash and charred particulate for miles, and Poway’s inland geography at the base of the Poway Grade acts as a catch-basin that funnels this debris into residential return systems. The smell persists because standard dust removal doesn’t address smoke residue baked onto duct surfaces. We source-remove this material with HEPA-contained agitation and negative-air extraction, then sanitize affected components. Call (361) 326-5060 if you’re still smelling smoke after a recent event.
Most 1970s – 1990s Poway homes need at least re-sealing, because original flex runs and rigid fiberglass duct board have cooked in 140°F-plus attics for decades. Cleaning without leak testing just pushes debris through the gaps we’ve found in nearly every system of this vintage. We camera-inspect every job and show you what we find before quoting repair. Call (361) 326-5060 for an inspection.
We seal the system under negative pressure with a Nikro machine, agitate debris from trunk lines and branches with Rotobrush rotary tools, capture everything in HEPA filtration, camera-inspect for disconnected or crushed runs, and pressure-test for leaks. In Poway, we also check for smoke and ash contamination that requires additional decontamination passes. The price is written before we start. Call (361) 326-5060 to schedule.
Every three to five years for routine maintenance, but after any significant Santa Ana wind event or nearby wildfire, test your return grilles for smoke smell. If you detect it, schedule an inspection regardless of interval. Poway’s fire-season loading is severe enough that we recommend more frequent checks than coastal San Diego homes need. Call (361) 326-5060 and we’ll assess whether you’re due.
Yes, and we recommend it. Dryer vent cleaning runs $120 – $200 when bundled with duct cleaning, and it uses the same contained extraction equipment. Poway’s dry inland climate and chaparral dust load mean dryer vents clog faster here than on the coast. Call (361) 326-5060 to add it to your appointment.
