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.

We’re the local Air Duct Cleaning crew dispatching from our Los Angeles office to serve Moorpark homes directly, and we know the specific problems this city’s tract-home ductwork develops after decades of Santa Ana winds and agricultural dust.
We’ve been working in Moorpark since 2004, from the older ranch homes near historic downtown to the planned subdivisions off Campus Park Drive and the neighborhoods ringing Moorpark College.

Why Hollis Air Duct Cleaning Is Moorpark’s Preferred Air Duct Cleaning Company
Moorpark homeowners don’t need another coupon in the mailbox promising a $79 whole-house special. They’ve seen those jobs end with a technician standing in the living room explaining why the real price is four times higher once he’s looked in the attic.
We work differently. The Garrison Standard means we price in writing before touching equipment, arrive inside the quoted window, and leave the site clean. Our 365-Day Done Right Promise covers every repair for a full year, if something fails, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.
Our phones are answered by a live person 24 hours a day, seven days a week. You’ll know your technician’s name before they arrive, and they’ll show up in a Hollis uniform with a background check you can verify. That’s The Garrison Code, and it’s how we operate in every Moorpark home we enter.
Air Duct Inspection in Moorpark
Air Duct Inspection in Moorpark starts with a camera-fed scope pushed through your supply and return lines, because the real problems in this city’s homes are often invisible from the registers. Most Moorpark properties built between the late 1980s and 2000s use flexible insulated duct runs in attic chases and wall cavities, not the rigid metal trunk lines found in older construction. That flexibility makes them prone to crushing, sagging, and disconnection, especially where Santa Ana wind pressure and thermal cycling have stressed the material for twenty-plus years. A standard inspection runs $150 – $250 and includes video documentation of what we find.
What the Camera Reveals
We feed a lighted borescope through the full length of each run, looking for collapsed sections, disconnected joints, and accumulation patterns that indicate where unfiltered air is entering the system. In Moorpark’s wind corridor, we often find the heaviest loading behind east- and northeast-facing returns, the exact path Santa Ana events travel.
When to Schedule
Book an inspection if you’ve noticed uneven heating or cooling between rooms, if your energy bills have climbed without explanation, or if it’s been more than five years since anyone looked inside the ducts. For homes near the Arroyo Simi or Moorpark College area, we recommend inspection every three years due to accelerated dust loading.
Residential Air Duct Cleaning in Moorpark
Residential Air Duct Cleaning in Moorpark means source removal from the full system, not just vacuuming what you can reach from the register. We use a Rotobrush rotary brush system to agitate debris off duct walls, coupled with a Nikro negative-air machine that maintains suction at 2,000+ CFM so nothing escapes into your living space during the process. A typical Moorpark home runs $350 – $650 depending on system size, accessibility, and whether we find damage requiring repair. Every job includes before-and-after photos of your own ducts, not stock images.
The Full System Approach
We clean supply ducts, return ducts, the main trunk, and the air handler cabinet. Many competitors stop at the easily reached trunk lines and call it done. We don’t. In Moorpark’s flexible-duct homes, the worst accumulation is often in the sloped runs behind bedroom walls, where agricultural dust and wildfire ash settle after Santa Ana events.
Sealing What We Find
Cleaning without sealing is half a job in this city. When our camera finds disconnected runs or crushed flex, we cut access panels, reconnect or replace the damaged section, and seal with duct mastic rated for California Title 24 energy standards. The price for this repair work is written separately and agreed before we start.
Trusted Brands We Service in Moorpark
We stock filtration and sealing products from Honeywell, Aprilaire, and Abatement Technologies for Moorpark customers, so replacement parts don’t require a two-week order delay. After cleaning, we often upgrade homes from original builder-grade MERV 6-8 filters to MERV 13 pleated media that captures the fine particulate Moorpark’s wind corridor pushes through the system. Our Nikro negative-air machines and Rotobrush rotary systems are maintained to manufacturer spec, not jury-rigged with hardware-store attachments. When we recommend a specific filter or sealing product, it’s because we’ve installed it in local homes and measured the results.
Common Air Duct Cleaning Problems We See in Moorpark Homes
- Contractors skip the flexible runs. Many outfits vacuum only the main trunk line and leave the sloped flex behind east-facing returns loaded with ash and agricultural dust. We clean the full system or we don’t take the job.
- Original filters are kept too long. Builder-grade MERV 6-8 panels installed in 1990s tract homes let fine particulate pass straight to the air handler and blower motor. We see blowers coated in gray dust that should have been caught at the grille.
- Crushed or disconnected attic runs go undetected. Without a camera inspection, a flex duct crushed by a storage box or disconnected at a coupling pulls unconditioned attic air into the system year-round, loading the house with dust and spiking energy bills.
- Cleaning without sealing wastes the customer’s money. A disconnected run behind a Moorpark College-area bedroom wall will be dirty again in six months if the gap isn’t sealed with mastic after cleaning.
Pricing for Air Duct Cleaning in Moorpark, CA
Here’s what air duct cleaning costs in Moorpark’s market:

FAQs About Air Duct Cleaning in Moorpark
Every three to five years for most Moorpark homes, and every three years for properties near the Arroyo Simi or Moorpark College where wind exposure is heaviest. The combination of Santa Ana events and agricultural dust from surrounding open space loads flexible ducts faster than rigid metal systems. Call (361) 326-5060 and we’ll assess your specific exposure.
Crushed flexible runs in attic chases, disconnected supply ducts behind wall cavities, and heavy accumulation of fine ash and dust behind east-facing returns. We were called to a two-story tract home off Campus Park Drive where the family had been sneezing every time the AC kicked on. Using a camera inspection we found a crushed flexible run in the attic chase plus a disconnected supply duct feeding a front bedroom. After cutting in an access panel, reconnecting the run, and sealing it with mastic, we ran the system on a MERV 13 filter and airflow at the register roughly doubled.
Cleaning alone is rarely enough if the inspection finds disconnected or damaged runs. In Moorpark’s flexible-duct homes, we seal with mastic after repair because unsealed gaps pull attic air and dust back into the system within months. The sealing price is written separately and agreed before we start.
MERV 13 pleated media for most Moorpark homes, especially those in the wind corridor near the Santa Susana Mountain foothills. The original builder-grade MERV 6-8 filters common in 1990s tract construction let fine particulate pass through to coat the blower and air handler. MERV 13 captures the ash, dust, and pollen that Santa Ana events push into the system without overloading standard residential equipment.
The Santa Ana winds peak in late fall and push fine, dry ash and dust from the Ventura County backcountry directly into east- and northeast-facing return grilles. Local techs know this stretch of homes gets especially loaded ducts during that season. If your returns face east and you haven’t had service in three years, you’re likely due.
