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 Westminster, CA
Air duct cleaning in Westminster, CA typically runs $300 – $600 for a whole-home system and addresses problems you won’t find inland: grease-laden ductwork from intensive year-round cooking, original 1970s flex lines that have never been sealed, and Santa Ana dust that keeps filters working overtime. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our Westminster crews carry rotary brush systems and negative-air machines built for the specific conditions in this city’s older tract homes and dense neighborhoods. Call us at (361) 326-5060 for a written estimate before any work starts.
Why Westminster Homes Are Different
Westminster’s housing stock is dominated by single-story ranch and two-story tract homes built from the 1950s through the 1980s. Many still run on original galvanized steel or early flex duct that was never properly sealed at the joints. In neighborhoods like Little Saigon, the combination of undersized ductwork and heavy daily cooking creates a problem standard residential cleaning rarely handles: grease and odor residues that coat duct interiors and re-circulate through every room.
The mild coastal climate means HVAC runs year-round for cooling and heating, so accumulation is constant, not seasonal. Santa Ana winds push fine dust and occasional wildfire ash through return-air grilles. Dense lot spacing and shared attic spaces let duct leaks transfer smells and allergens between adjacent homes. Technicians here need degreasing capability, not just vacuum power.
Our Main Westminster Services
Westminster homeowners call us for three jobs, each handled on its own dedicated page with local pricing and conditions.
Air Duct Cleaning in Westminster
We clean supply and return ductwork with Rotobrush rotary brush systems and Nikro negative-air machines, pulling debris toward the vacuum rather than pushing it into your living space. In Westminster, we often find kitchen exhaust ducts coated with grease that requires degreasing agent before rotary brushing. Every job gets a written price upfront and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Westminster covers full pricing, what’s included, and how we handle the grease problems specific to this market.

Dryer Vent Cleaning in Westminster
Dryer vent blockages are a fire hazard, and Westminster’s older homes often have long, convoluted vent runs through shared walls or roof caps that complicate access. We clear lint buildup with rotary tools and inspect the full run for damage or improper slope. Pricing is flat per system, agreed in writing before we touch anything. Dryer Vent Cleaning in Westminster has the full breakdown for local homes.

Duct Sealing in Westminster
Original ductwork in Westminster’s 1960s – 1980s tracts leaks at joints and connections, wasting conditioned air and pulling attic dust and cooking odors into the system. We seal accessible joints with mastic and mechanical fasteners, then pressure-test to verify results. Sealing is often the right follow-up to cleaning on these older systems. Duct Sealing in Westminster explains when sealing makes sense and what it costs.

FAQs About Air Duct Cleaning Company in Westminster
Standard residential duct cleaning requires no permit in Westminster. Duct sealing that involves modifying or replacing duct sections may need a permit if it alters the HVAC system’s capacity or routing; we flag this during estimate and can advise on whether your scope triggers city review. Call (361) 326-5060 and we’ll walk through your specific setup.
We schedule Westminster appointments within a few business days, with dispatch coordinated from our Los Angeles office. Emergency dryer vent blockages get priority due to fire risk. Call (361) 326-5060 for next available.
Yes, when grease and organic residue are the source. Standard vacuuming alone won’t do it; we use degreasing agents followed by rotary brush agitation on duct interiors, then negative-air extraction. Persistent odors from shared-wall air leaks may also need duct sealing to stop cross-flow from adjacent units.
