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 Gilroy, CA
Air duct cleaning in Gilroy typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. What makes Gilroy different from neighboring Morgan Hill or Los Gatos is the agricultural dust from surrounding garlic and produce fields, which settles into ductwork and creates a gritty, organic debris mix that demands specialized agitation and filtration methods. Hollis Air Duct Cleaning dispatches crews from our San Francisco Bay Area office to serve Gilroy homes directly, bringing Rotobrush rotary systems and Nikro negative-air machines to handle the specific conditions this valley floor presents. Call (361) 326-5060 for a free estimate.
Why Gilroy Homes Are Different
Gilroy’s housing stock splits between older downtown bungalows from the early 1900s and suburban tract homes built from the 1970s through the 2000s. Many of these older systems still run original galvanized ductwork or early flex duct that accumulates debris faster than modern equivalents and is prone to leaks and pest intrusion. The clay soils from nearby open land track indoors and combine with field dust, creating a heavier particulate load than we see in coastal towns.
The climate here works against clean ducts too. Hot, dry summers regularly exceed 100°F, while cool, damp winters create expansion and contraction cycles that crack seams and pull in dust, pollen, and agricultural particles. Without ocean breeze to disperse airborne debris, dust settles and stays. During garlic harvest season, roughly July through September, the fine particulate matter and strong odor can penetrate ductwork and linger until properly cleaned with deodorizing treatments, a problem virtually unheard of in neighboring cities.
Our Main Gilroy Services
Most calls we field from Gilroy homeowners fall into three categories: whole-system duct cleaning, dryer vent maintenance, and sealing leaky duct runs that waste conditioned air.
Air Duct Cleaning in Gilroy
We use a rotary brush system from Rotobrush to agitate debris off duct walls, paired with a Nikro negative-air machine that maintains suction throughout the job so nothing resettles in your home. In Gilroy, this matters more than in most markets because agricultural dust packs harder than ordinary household lint. We also apply deodorizing treatments during garlic harvest season when field odors have penetrated the system. Air Duct Cleaning in Gilroy covers our full process and what to expect on arrival.

Dryer Vent Cleaning in Gilroy
Lint buildup in dryer vents is a leading cause of house fires nationwide, and Gilroy’s hard water and dusty environment can accelerate blockage. We run a rotary brush through the full vent line to the exterior termination, then verify airflow with a gauge. If your dryer takes longer than one cycle to dry a standard load, the vent is likely restricted. Dryer Vent Cleaning in Gilroy explains our safety check and written pricing.

Duct Sealing in Gilroy
Leaky ducts pull attic dust and crawlspace air into your living space and can waste 20 – 30% of your heating and cooling energy. In Gilroy, thermal expansion from hot summers and cool winters opens gaps at joints and seams. We seal accessible ductwork with mastic and reinforced tape, then pressure-test to confirm results. Duct Sealing in Gilroy details how we locate leaks and what improvement you can measure on your next utility bill.
