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 Westminster
Air duct cleaning in Westminster typically costs $300-$600 for a full residential system and $450-$1,200 for commercial kitchens, with most jobs scheduled within a few business days and completed in three to five hours. Our dispatch team coordinates from our Los Angeles office, and our crews serve Westminster homes and businesses daily, carrying Rotobrush and Nikro equipment that’s sized for both the post-WWII tract homes off Brookhurst Street and the dense commercial kitchens along Bolsa Avenue.
We’ve been working in Westminster since 2005, and we know the local housing stock: the 1940s-to-1970s neighborhoods where flex duct was retrofitted through attics decades ago, the persistent marine-layer humidity that settles in during June Gloom, and the specific buildup that pho restaurants and wok kitchens produce. When you call (323) 918-4345, a live person answers, and we’ll give you a written price before any work starts.
Why Morton’s Air Duct Cleaning Is Westminster’s Preferred Air Duct Cleaning Company
Westminster homeowners call us back because we treat their houses like we would our own. Our technicians wear shoe covers and lay drop cloths from the front door to the attic access before touching anything. We work around nap schedules when there’s a toddler down the hall, and we keep the Rotobrush unit on low speed near pet areas until we know how the dog reacts to the sound.
Every job carries our 365-Day Done Right Promise. If something isn’t right, we make it right. That’s stamped on every invoice, not offered only when someone complains. Our background-checked, uniformed technicians work to the Cedarwell C.A.R.E. values, and we leave a photo of the clean-up before we go so you can see the work was done and your floors are intact.
We’re part of the Cedarwell family of independently owned companies, and Morton’s has held to the Cedarwell Care Promise since our founding in 2005: written price upfront, shoe covers and drop cloths on every visit, and visual proof of the clean-up. No exceptions.
Air Duct Inspection in Westminster
Air Duct Inspection in Westminster starts with a camera run through your supply and return lines, looking for the specific problems this city’s housing stock produces: sagging flex duct that was strung through attic spaces in the 1970s or 1980s, crushed runs where someone stepped between joists, and disconnected boots that leak conditioned air into the insulation before it ever reaches your bedroom. A typical residential inspection in Westminster runs $150-$250, and we apply that toward your cleaning if you move forward.
What We Look For in Older Attic Systems
Most Westminster homes east of Beach Boulevard were built without central air and had ductwork added later. That means flex runs stapled to rafters, often with inadequate support straps. We photograph every sag, every tear, and every disconnected collar so you see exactly what we’re seeing in real time.
Commercial Kitchen Inspection Protocol
Restaurants along Bolsa Avenue and the Little Saigon corridor need a different inspection scope. We check for grease-laden vapor buildup in exhaust ducts, fire-code clearance issues, and the layered residue that pho stock simmering produces. Our report includes a cleaning protocol recommendation and a written price for the degreasing work.
Residential Air Duct Cleaning in Westminster
Residential Air Duct Cleaning in Westminster addresses the decades of accumulation that post-WWII tract homes hide in their attic ductwork: construction debris from the original build, dust from the 1960s and 70s when windows stayed open year-round, and the gradual coating of skin cells, pet dander, and pollen that settles in systems where air moves slowly. A typical whole-home cleaning in Westminster runs $300-$600, depending on system size and accessibility.
How We Protect Your Home During the Clean
We lay Guardsman drop cloths at the entry point and every hallway transition. Shoe covers stay on until we exit. If your system has a return in the nursery or near the dog’s bed, we seal that zone first and run our Nikro HEPA vacuum at the air handler so nothing migrates room to room.
The Real Fix Is Often Sealing, Not Just Cleaning
On a mid-1960s tract home near Bolsa Avenue and Magnolia Street, our tech ran a camera inspection on a retrofitted attic flex system and found the original run sagging with a disconnected supply duct feeding a bedroom register. We reconnected the run, hand-agitated the decades of debris, and pulled it out under negative pressure with HEPA filtration at the air handler. The homeowner’s blower motor amp draw dropped and the June Gloom mildew smell cleared within days. That job was $485, and it included the reconnection and sealing work.
Trusted Brands We Service in Westminster
Our trucks carry professional-grade equipment from Rotobrush, Nikro, Honeywell, Aprilaire, and Abatement Technologies, not the rental-grade machines you can pick up at a hardware store. We stock common replacement parts for Westminster customers so we’re not ordering a collar or a register boot and making you wait. If your system has Aprilaire media filters or a Honeywell electronic air cleaner, we know how to remove and reinstall them without damaging the housing. For the commercial accounts along Bolsa Avenue, our Abatement Technologies HEPA vacuums handle the heavy grease loads that standard extractors can’t touch.
Common Air Duct Cleaning Problems We See in Westminster Homes
- Sagging or disconnected flex duct in attic retrofits. Westminster’s post-WWII tract homes were built without central air, and the flex duct added later was often strung with too few support straps. Over decades, the weight of dust and moisture causes runs to sag, kink, or pull completely free of the register boot.
- June Gloom humidity feeding mold in rarely-used ducts. Westminster sits 8-10 miles from the coast, and the marine layer that rolls in May through June infiltrates attic spaces where air conditioning runs infrequently. Dust that hasn’t been disturbed in twenty years becomes a substrate for mildew colonization.
- Crushed runs from foot traffic in tight attics. The original installers in the 1970s and 80s often ran flex duct across joist bays without walk boards. Every HVAC tech, electrician, or homeowner who’s stepped in the wrong place since then has compressed the duct, restricting airflow and creating debris traps.
- Little Saigon commercial grease buildup. The pho restaurants and wok kitchens along Bolsa Avenue produce a specific multi-layer residue: rendered pork and beef fat from stock pots, carbonized wok char, and fish-sauce vapor that condenses in cool ductwork. Standard restaurant degreasing doesn’t break it down. We use an aggressive Westminster-specific protocol with heated degreaser and extended contact time.

FAQs About Air Duct Cleaning in Westminster
The marine-layer humidity that Westminster gets during June Gloom infiltrates attic ductwork and condenses on dust that hasn’t been disturbed in decades, creating ideal conditions for mildew growth. You don’t need heavy AC use for this to happen; the temperature differential between cool morning air and warm attic surfaces is enough. A full system cleaning with HEPA-contained extraction removes the biological growth and the debris it feeds on. Call (323) 918-4345 and we’ll inspect with a camera to confirm the source.
Yes. The combination of rendered pork and beef fat from long-simmering stock, high-heat wok char, and fish-sauce vapor creates a multi-layer residue that standard Southern California restaurant degreasing cannot break down without extended contact time and heated degreaser application. We’ve developed a Westminster-specific protocol for Little Saigon commercial kitchens because no neighboring Orange County city produces this specific buildup at this density. We’ll quote the protocol and price after an on-site inspection.
Sagging flex runs with inadequate support, crushed sections from decades of foot traffic, disconnected boots where the duct has pulled free of the register, and accumulation of construction debris plus household dust from the pre-air-conditioning era when windows stayed open. We often find that the real problem isn’t dirty ducts; it’s disconnected ducts leaking conditioned air into the attic. Our inspection identifies what’s actually wrong, and we quote the cleaning plus any reconnection or sealing work separately before we start.
We show you. Our camera inspection captures before-and-after footage of the same duct sections, and our HEPA vacuum includes a clear debris collection chamber you can inspect. We also leave a photo of the clean-up before the crew leaves, so you see that your floors, registers, and surrounding surfaces are intact. The Cedarwell Care Promise includes this visual documentation on every job.
We service and clean around Aprilaire, Honeywell, and other major brands without voiding warranties or damaging housings. Our technicians carry the right tools to remove and reinstall media cabinets and electronic cells without stripping screws or cracking plastic. If your Westminster home has a whole-house air cleaner, we’ll note the model during scheduling so the tech arrives prepared.
