AfterHow Much Does Air Quality & Sanitizing Cost in North Hollywood?
Air quality and sanitizing work in North Hollywood typically runs $350 to $1,100 for a standard home, with whole-home duct cleaning landing most often between $450 and $850 and sanitizing treatment adding roughly $75 to $200 on top. Larger homes, heavy contamination, or a repair discovered mid-job push the total past $1,500. Each of those figures is an estimate – the written estimate you get before any work begins is what sets your final price.
We’re Onyx Duct Cleaning, and we do one thing: indoor air quality. Duct cleaning, dryer vent cleaning, and duct repair. That focus is why our quotes look the way they do. We bring the Rotobrush contact-cleaning system, Nikro HEPA vacuums, and Abatement Technologies filtration equipment that restoration crews use, because a shop vac and a promise don’t clean a duct system. If you want to know what the work actually costs before anyone sets foot in your house, this page lays it out. We answer 24/7, and dispatch runs 7am to 7pm, Sunday through Friday.

Air Quality & Sanitizing Cost Breakdown (2026)
Here’s how the numbers break down line by line for a typical North Hollywood home. Treat these as ranges, not quotes – square footage, how many vents you have, and what’s actually inside the ducts move the total up or down. The estimate is free and always written.
| Service | Typical 2026 range (North Hollywood) | What’s included |
|---|---|---|
| Whole-home air duct cleaning | $450 – $850 | Contact cleaning of all supply and return runs, register removal, HEPA extraction |
| Sanitizing treatment | $75 – $200 | Fogging or spray application of an antimicrobial treatment across the cleaned duct interior |
| Dryer vent cleaning | $120 – $250 | Full run from the dryer to the exterior termination, lint removal, blockage check |
| Air duct repair (per section) | $250 – $900 | Sealing or reconnecting disconnected, crushed, or leaking duct runs |
| Single-system / small condo cleaning | $350 – $500 | Fewer runs, single air handler, limited register count |
| Large or heavily soiled home | $850 – $1,500+ | Multiple systems, high register count, heavy debris, longer extraction time |
A few things push the number up. More vents mean more time at the duct wall, one run at a time. Heavy debris – common after a renovation, a recent HVAC swap, or years without service – means slower extraction and more containment care. And if we find ductwork that’s come apart or crushed during the cleaning, that falls under repair, not cleaning. That’s where a job can climb. We don’t quote a repair we haven’t seen, so if we find one, we show you what we found and price it before touching it.
What pulls the number down: fewer registers, easy access to the air handler, and a system that’s been serviced at some point in its life. A single-system condo in North Hollywood is a different job from a house with two air handlers and a long attic run, and it’s priced that way.
What Affects Air Quality & Sanitizing Pricing in North Hollywood
Local conditions matter more than most price guides admit. North Hollywood is full of older homes, apartments, and buildings that were reworked over the decades, and the ventilation in each of those is a little different. These are the factors that move the price here:
- Number of registers and returns. Every vent has to be cleaned individually at the duct wall with the Rotobrush system. A four-bedroom house with a dozen registers is a longer, pricier job than a one-bedroom apartment.
- System age and original install quality. In a lot of North Hollywood housing stock, ductwork was added or altered after the original build. Crushed runs, taped-together joints, and disconnected sections are more common in those systems, and each one is either a cleaning challenge or a repair.
- Dust, pollen, and street grime. North Hollywood sits in the San Fernando Valley basin, where fine dust and seasonal pollen work their way into return air. Homes near busy corridors pull more particulate into the system, which means more frequent cleaning and heavier loads when we get there.
- Renovation dust. Drywall dust, sawdust, and construction debris settle into ducts fast. If you’ve just remodeled, the cleaning is more involved and priced higher than a routine service.
- Pet hair, dander, and occupants with allergies. A home with pets or someone with asthma usually wants both cleaning and a sanitizing treatment. That’s the add-on line in the table above.
- Duct repair needed. This is the big swing. If the system has a leak, a crushed section, or a disconnected run, cleaning alone won’t fix it – air loss and contamination entry continue. We quote repair separately because it’s a separate job.
One more factor: dryer vents. A clogged dryer vent isn’t a cleaning convenience, it’s a fire risk, and we treat it that way. A run that’s short and straight is quick to clear. A long, partially crushed vent behind a stacked laundry setup takes more time and more care. If your dryer is drying slowly or the vent hasn’t been touched in years, budget for it.
What Does a Sanitizing Treatment Add, and Is It Worth It?
Sanitizing typically adds $75 to $200 to a duct cleaning, and it’s worth it when there’s a reason – musty odor, visible microbial growth, water damage history, pets, or someone in the house with respiratory sensitivity. It’s applied after the ducts are physically clean, because treatment on top of debris doesn’t accomplish much.
One important boundary: we’re a duct cleaning and repair specialist, not a mold remediation contractor. If we find extensive microbial growth inside the system, the honest answer is that remediation comes first, and we’ll tell you that rather than spray over it. Our Abatement Technologies equipment reflects a containment standard borrowed from restoration work, which means we take what’s coming out of the ducts seriously – but it doesn’t make us a remediation company, and we won’t pretend otherwise.
What About Air Duct Repair Cost?
Duct repair is the line that surprises people, and it’s why we offer it as a standalone service. A repair runs $250 to $900 per section in North Hollywood, depending on access and what’s wrong. A crushed flex run in an accessible attic is at the low end. A disconnected trunk line behind finished walls is at the high end. Here’s the reason it matters: we clean what’s in your ducts, and we also fix what’s wrong with them. Cleaning around a leak leaves the leak in place. We can resolve the root cause instead.
How to Save on Air Quality & Sanitizing
There’s no coupon trick here – the honest ways to keep the number down are structural. A few that actually work:
- Bundle duct cleaning with dryer vent cleaning. A single visit covers both the air pathway and the fire risk, and it usually costs less than booking them separately. Ask about it when you get your estimate.
- Clean before a renovation, not after. If you’re about to remodel, sealing registers or scheduling a cleaning on the back end avoids a heavier, pricier job later. Construction dust is the most expensive debris to remove.
- Fix a known leak early. A small disconnected run costs less to repair now than after it’s pulled contaminants into the system for a season. Catch it during a routine cleaning.
- Know your register count. Tell us how many vents you have when you call. It sharpens the estimate and avoids surprises on-site.
- Get the free written estimate. The estimate is free and the price is set by it. Call (833) 589-9715 and we’ll price the job before anyone touches a duct.
One thing we won’t do is lowball a number over the phone and raise it on arrival. The estimate is what it is. If we find something during the job that changes the scope, we stop, show you, and re-price before proceeding. We show you the system, not just the invoice.
Air Quality & Sanitizing in North Hollywood: What Makes This Market Different
North Hollywood is a tight mix of single-family homes, older apartment buildings, and converted commercial space, and the ventilation in each has its own history. The Valley’s dry, dusty air and the seasonal pollen load mean return-air systems here pull in more fine particulate than homes closer to the coast. That shows up as faster dust accumulation on registers and a shorter interval between needed cleanings. Homes near the busier corridors and the nearer the 170 and 134 a home sits, the more street particulate the system takes in.
That context matters for pricing because heavier loads take longer. It also matters for how often you should book service. A well-maintained system in a low-dust home may go years between cleanings. A system in a home with pets, a recent remodel, or someone with allergies might need attention far sooner. We’d rather tell you the honest interval than sell you a plan you don’t need. You can read more about how we approach local homes on our North Hollywood page.
Contractor-Grade Equipment, Residential Pricing
Here’s the part most price guides skip: the equipment is why the price is what it is. Rotobrush contact cleaning physically dislodges debris at the duct wall instead of just agitating it. Nikro HEPA vacuums capture particles down to 0.3 microns and contain them rather than blowing them back into the room. Abatement Technologies filtration is the standard restoration and abatement crews work to. Honeywell and Aprilaire system familiarity means we understand the filtration side of your HVAC, not just the duct interior. None of that is a gimmick. It’s the difference between cleaning a duct and cleaning a duct system.
We’ve been doing this work since 2013 – 13 years in the trade as a company – and the through-line has been the same: bring the right equipment, show your process, and fix what’s actually wrong. That’s the whole offer.
FAQs – Air Quality & Sanitizing Cost
How much does air duct cleaning cost in North Hollywood in 2026?
Whole-home air duct cleaning in North Hollywood typically runs $450 to $850, with small condos starting around $350 and large or heavily soiled homes climbing to $1,000 or more. Sanitizing adds roughly $75 to $200. Call (833) 589-9715 for a free written estimate on your specific system.
Is it cheaper to clean the ducts or replace them?

Do I need a sanitizing treatment, and what does it cost?
Only if there’s a reason – odor, past water intrusion, pets, allergies, or visible growth. It adds $75 to $200 to a cleaning. If there’s extensive growth, remediation comes first and we’ll say so. Call (833) 589-9715 and we’ll help you figure out whether you need it.
