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.

AfterHow Much Does Air Quality & Sanitizing Cost in Los Angeles?
Air quality and sanitizing service in Los Angeles typically runs $450 to $1,600 for a whole-home duct cleaning and sanitizing package, with most single-family homes landing between $650 and $950. If you only need standalone air sanitizing (UV or hydroxyl treatment without duct cleaning), expect $250 to $600. Add-on treatments like coil cleaning, HEPA filtration upgrades, or dryer vent work usually tack on $90 to $450 depending on scope.
Those ranges aren’t guesses – they reflect what Los Angeles homeowners actually pay across neighborhoods from Sherman Oaks to Silver Lake. What shifts the number is square footage, system type, how many returns the house has, and whether we’re dealing with something beyond dust, like wildfire ash, pet dander, or post-renovation debris.
Every job at Linden Air Duct Cleaning starts with a written price before any work begins. No surprise invoices at the end. Call (980) 447-2498 and we’ll give you a free estimate up front.

Air Quality & Sanitizing Cost Breakdown (2026)
Here’s what Los Angeles homeowners actually see on an estimate. These are real ranges for the LA market, not national averages stretched to fit.
| Service | Typical Price Range |
|---|---|
| Whole-home air duct cleaning (up to 10 vents) | $450 – $750 |
| Air duct cleaning (larger homes, 15 – 25 vents) | $800 – $1,600 |
| Air sanitizing treatment (UV-C or hydroxyl, standalone) | $250 – $600 |
| Fogging / antimicrobial sanitizing solution (per system) | $150 – $325 |
| Dryer vent cleaning | $125 – $295 |
| Air duct repair (sealing, reconnecting, patching) | $180 – $650 |
| HVAC coil cleaning | $180 – $450 |
| HEPA or high-MERV filtration upgrade | $95 – $325 |
| Duct cleaning + sanitizing bundle (most common) | $650 – $1,100 |
The bundle is where most LA homeowners land, because cleaning without sanitizing leaves you with clean ducts and the same airborne problems. Sanitizing without cleaning pushes disinfectant into a layer of dust. Do both, and the ductwork goes back into service actually clean.
What moves the number up or down: square footage and vent count, number of HVAC systems (dual-zone LA homes cost more), how accessible the ductwork is, whether there’s mold or pest contamination requiring extra handling, and whether you schedule during peak season (late summer and after fire season are our busiest months).
What Affects Air Quality & Sanitizing Pricing in Los Angeles
- Vent count and square footage. A 1,400 sq ft bungalow in Highland Park with 8 vents takes a different path than a 3,200 sq ft home in Encino with 22 vents and two air handlers. Vent count is the single biggest driver. Each additional run adds time, equipment passes, and material.
- Number of HVAC systems. A lot of LA homes run dual-zone or even triple-zone systems thanks to the climate split between the Valley and the coastal side. Each system gets its own cleaning cycle and sanitizing treatment, so a two-system home typically costs 40 to 60 percent more than a single-system home of the same size.
- Contamination type. Standard dust and dander cleaning is our baseline. Wildfire ash (the kind that drifts into Sherman Oaks and Pasadena after a Santa Ana wind event) requires finer filtration and more passes. Rodent or pest debris, post-renovation drywall dust, and visible mold all add cost because they need containment, disposal, and sometimes a follow-up inspection.
- Ductwork condition and accessibility. Flexible duct in a crawlspace cleans differently than rigid metal duct buried behind drywall. If we find disconnected joints or crushed runs, we’ll quote a repair alongside the cleaning, since sanitizing a leaky system just ventilates your attic. See our air duct repair in Los Angeles page for how those repairs are priced.
- Sanitizing method. UV-C lamps are a fixed-installation cost; hydroxyl generators and fogging treatments are per-service. Some homes get more value from one than the other depending on allergy concerns, humidity levels, and whether anyone in the house has respiratory sensitivity.
- Season and scheduling. Post-wildfire smoke events, spring allergy season, and the tail end of summer AC season all spike demand in Los Angeles. Booking during a quieter window can sometimes mean a slightly lower quote, but we don’t run surge pricing – the written price is the price.
One more factor Los Angeles homeowners ask about: the age of the home. Pre-1980 homes in neighborhoods like Echo Park and West Adams sometimes have original ductwork with asbestos-wrapped sections or degraded flex runs. We inspect and flag anything that needs a specialist before we touch it. That’s part of The Threshold Standard – nobody gets surprised mid-job.

How to Save on Air Quality & Sanitizing
You don’t need to cut corners to keep the bill reasonable. Here are the moves that actually work in the LA market.
- Bundle cleaning and sanitizing in one visit. A combined service runs $650 – $1,100 in most cases, versus $450 – $750 for cleaning alone plus $250 – $600 for standalone sanitizing. Bundling saves you the second trip charge and usually 15 to 25 percent off the combined total.
- Get the dryer vent cleaned at the same time. If it’s been more than a year, add it while we’re already on site. Dryer vent cleaning alone runs $125 – $295, but as an add-on during a duct visit it typically lands at the lower end. It’s also the single most overlooked fire-safety item in LA homes – lint buildup is the leading cause of dryer fires, and the bypass problem (lint escaping past the trap into the vent run) is something most homeowners never see until it’s cleared.
- Address repairs before they compound. A $180 duct repair today prevents a $600+ cleaning-and-resealing job next year. Every repair job comes with a written guarantee and a free second visit if the repair fails.
- Ask about filtration upgrades at quote time. A high-MERV or HEPA upgrade runs $95 – $325 and extends the life of the cleaning. Filter upgrades are cheaper as part of a scheduled service than as a standalone visit.
- Skip the upsells you don’t need. If your ducts are clean and your air quality issue is seasonal pollen, sanitizing may not help as much as filtration. We’ll tell you that. Stating the honest recommendation is worth more to us than a bigger invoice.
- Book a free estimate. There’s no charge for the quote, and the price you get in writing is the price you pay. Call (980) 447-2498 and a live person will answer, day or night.
One thing we won’t do: quote you a low number over the phone and raise it on site. Industry-wide, that’s the most common complaint about duct cleaning. Our written-price policy exists because of it.
How Long Does Air Quality & Sanitizing Take in Los Angeles?
Most LA homes take 2 to 4 hours for a full duct cleaning and sanitizing package. Larger homes with multiple systems can run 5 to 6 hours. Standalone sanitizing is quicker – usually 60 to 90 minutes. Dryer vent cleaning adds 30 to 45 minutes.
You don’t need to leave the house, and you don’t need to move furniture. We work with a negative-pressure extraction setup so dislodged dust gets pulled into our equipment rather than pushed into your living room. The technician will show you before-and-after photos of the duct interiors when the job is done.
FAQs – Air Quality & Sanitizing Cost
How much does air duct cleaning and sanitizing cost in Los Angeles?
A bundled duct cleaning and sanitizing job in Los Angeles runs $650 to $1,100 for the average home. Larger homes with two systems can reach $1,600. Call (980) 447-2498 for a free written estimate tailored to your home.
Is sanitizing worth the extra cost, or is cleaning enough?
Sanitizing adds $150 to $600 and is worth it if anyone in the house has allergies, asthma, or if you’ve had a wildfire smoke event, water intrusion, or pest issue. If your ducts are just dusty and nobody’s symptomatic, cleaning alone may be enough. We’ll tell you honestly which applies to your home when we quote it.
How much does a UV or hydroxyl air purifier cost installed in Los Angeles?
UV-C and hydroxyl systems run $250 to $600 installed, depending on whether it’s a single-lamp or multi-lamp setup for a multi-zone home. Call (980) 447-2498 for an exact quote – estimates are free.
Is it cheaper to repair or replace ductwork in Los Angeles?
Repair is almost always cheaper – repair runs $180 to $650, while full duct replacement typically starts at $2,500 and climbs fast. We only recommend replacement when the ductwork has collapsed, has widespread mold, or was installed improperly throughout. Otherwise we repair, guarantee the work in writing, and return free of charge if the repair doesn’t hold.
Can you come today?
Same-day and next-day appointments are often available in Los Angeles, especially for dryer vent and repair work. Cleaning and sanitizing jobs typically book within a few days. Our phones are answered by a live person 24/7, so call (980) 447-2498 any time and we’ll give you the soonest opening.
Who is coming to my house, and how do I know they’re safe?
Every Linden technician is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge shown at the door. Before the visit, you’ll get the tech’s name and photo by text. This is our standing practice, not an upgrade – we work to The Threshold Standard on every job, and it’s a real reason many of our Los Angeles customers are homeowners who are often home alone or managing kids during the appointment.
What’s Included in a Linden Air Quality & Sanitizing Job
Every job includes a written price before we start, professional-grade equipment from Rotobrush and Nikro, before-and-after photo documentation, and a 365-Day Done Right Promise. If the work isn’t right, we make it right in writing. If a covered repair fails, we come back at no charge.
The product lineup matters too. We work with Honeywell, Aprilaire, Abatement Technologies, and Guardsman filtration and air-quality products, matched to your system rather than sold off a rack. If your home would do better with a specific MERV rating or a particular filter housing, that’s what goes in.
Linden Air Duct Cleaning has served homeowners since 2004 as part of the Threshold Group family. We’re an independently owned and operated location, and our team in Los Angeles answers to the same written-price and written-guarantee commitments we’ve held since day one.

What Our Customers Say
"Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N."We had construction dust packed into every register after a remodel. They sealed off the returns, used negative pressure, and left the floors cleaner than they found them."
