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.

Why Hollis Air Duct Cleaning Is Los Gatos’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Los Gatos on showing up inside the quoted window, pricing in writing, and leaving the site clean. The Garrison Standard requires it. Our technicians are background-checked and uniformed; you’ll know who’s arriving before they walk through your door. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.
Our 365-Day Done Right Promise covers every job in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit. That promise holds whether we’re cleaning ducts in a historic bungalow near Tait Avenue or a hillside estate off Black Road.
Los Gatos homeowners have told us the same thing for years: they called us because another company quoted a low price over the phone, then doubled it at the door. That doesn’t happen here. The price is written down before work starts, and it does not move.
Residential Air Duct Cleaning in Los Gatos
Residential Air Duct Cleaning in Los Gatos means more than blowing dust out of vents. Most homes here were built between the early 1900s and 1970s, with original galvanized steel ducts or early flexible ductwork that’s now brittle, leaky, and often crushed in crawlspaces. After wildfire seasons, we find fine ash coating the interior of these systems, cycling smoky odors through bedrooms and living rooms even when windows are closed. A proper residential clean in Los Gatos requires HEPA filtration, negative-air containment, and often duct sealing to stop the real problem: leaks that pull contaminated attic or crawlspace air back into the system.
A typical residential duct cleaning in Los Gatos runs $350 – $650 for a single-system home, with larger hillside properties and multi-zone setups ranging from $650 – $1,200. Every price is written and agreed before work begins.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back to the air handler. In Los Gatos’s older homes, we often find return ducts disconnected at the plenum, pulling unfiltered crawlspace air instead of room air. We clean both sides of the system and check every connection with a camera.
Video Inspection and Sealing
Our Rotobrush rotary brush systems and Nikro negative-air machines agitate and extract debris, but the camera tells the real story. We show homeowners what we found: crushed flex, disconnected boots, ash buildup. Then we seal with mastic and mesh where needed, priced separately and agreed in writing.
Commercial Air Duct Cleaning in Los Gatos
Commercial Air Duct Cleaning in Los Gatos serves restaurants along North Santa Cruz Avenue, medical offices near Los Gatos-Saratoga Road, and professional buildings throughout the 95030 and 95032 zip codes. Commercial systems run harder and longer than residential units, with rooftop package units and extensive flex trunk lines that accumulate grease, dust, and construction debris over years of operation. Los Gatos’s commercial building stock includes historic structures with limited access and newer developments with complex VAV systems, each requiring different equipment configurations and containment strategies.
Commercial duct cleaning in Los Gatos typically ranges from $800 – $2,400 depending on system size, access difficulty, and contamination level. We schedule around your business hours to minimize disruption.
Full System Cleaning and Maintenance Plans
Our commercial crews use Nikro negative-air machines and HEPA filtration to contain debris during cleaning. We document before-and-after conditions with photos and provide written reports for property managers and facility directors. Maintenance plans are available for annual or semi-annual service.
Kitchen Exhaust and Grease Duct Cleaning
Los Gatos restaurants face strict Santa Clara County fire codes for grease duct maintenance. We clean hood-to-fan systems with rotary tools and degreasing agents, providing the documentation your fire inspector requires.
Trusted Brands We Service in Los Gatos
Hollis Air Duct Cleaning works with professional-grade equipment from Rotobrush and Nikro, and we install filtration products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools and components commercial crews use, not hardware-store gear. For Los Gatos homeowners, that means replacement filters, UV lamps, and media upgrades are available without waiting for special orders. Our technicians carry common Honeywell and Aprilaire filter sizes on every truck, and we stock Abatement Technologies HEPA filtration media for post-wildfire cleanups that require immediate response. When a hillside estate off Alma Bridge Road needs a multi-zone filtration upgrade or a Downtown Los Gatos shop needs commercial-grade containment, we have the parts and the training to do it right.
Common Air Duct Cleaning Problems We See in Los Gatos Homes
- Wildfire ash and smoke odor in original galvanized ducts. After fires like the CZU Lightning Complex, fine ash penetrates attic vents and settles in duct interiors. Standard cleaning without HEPA containment and odor-neutralizing treatment leaves particles behind that recirculate for months.
- Crushed or disconnected flex runs in crawlspaces and above vaulted ceilings. Los Gatos’s older homes often have flex ductwork installed in the 1970s or 1980s that’s now sagging, torn, or completely separated from the boot. Cleaning never reaches these sections until they’re reconnected or replaced.
- Moisture and mold in poorly sealed return ducts during winter rains. Los Gatos’s winter wet season introduces humidity through crawlspace vents. Leaky return ducts pull that moist air directly into the system, creating mold conditions that surface cleaning won’t fix.
- Multi-zone systems with inaccessible ductwork above vaulted ceilings. Newer hillside estates often hide duct runs above tongue-and-groove ceilings or behind built-in cabinetry. Cleaning these requires specialized access tools and camera-guided agitation, not standard vent-insertion methods.

FAQs About Air Duct Cleaning in Los Gatos
Yes. Los Gatos’s historic downtown and hillside overlay codes often prohibit new exterior vent penetrations, so we must set up HEPA filtration and negative-air containment entirely inside the home. Our crews plan for this on every Los Gatos job, using Nikro portable HEPA units and interior exhaust routing that complies with local rules.
Original galvanized ducts from the 1920s to 1950s corrode at the seams, and flex runs added in later decades often sag, crush, or disconnect. Surface cleaning misses the leaks that pull contaminated crawlspace or attic air back into your system. We camera-inspect, then seal with mastic and mesh where needed.
Yes. We use camera-guided rotary brush systems and specialized access tools to reach duct runs hidden above tongue-and-groove or beam ceilings. These jobs take longer and cost more, but we price them in writing after a site visit, not over the phone.
The town’s noise ordinance bars loud compressor-driven equipment before 8 a.m. We schedule the negative-pressure and agitation phases for mid-morning or later to avoid complaints, rescheduling, and added cost. Your appointment window reflects this.
Expect fine ash in the duct interior, possibly coating the entire system. We set up interior HEPA containment, agitate with rotary brushes, extract with negative air, and apply odor-neutralizing treatment. If ducts are leaky, sealing is usually required to stop odor recurrence. Call (361) 326-5060 for an inspection and exact quote.
