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 Duct Cleaning Cost in Los Angeles?
Most Los Angeles homes run $450 to $1,100 for a full air duct cleaning, with the average single-family house landing around $650. If you’ve got a two-story home in the Valley or a larger place on the Westside with a big attic system, expect the upper end. Small condos and bungalows with short runs often come in under $500.
That range covers the whole job: negative-air extraction, brush agitation of every accessible duct, register and grille cleaning, and a documented before-and-after of your system. What it doesn’t cover is the surprise you get when a contractor quotes $299 on the phone and revises it to $900 once he’s standing in your hallway. At Kestrel Air Duct Cleaning, you get the written price before a single vent is touched. That’s not a promotion. It’s how we work every job under the Kingswell Guarantee.
Key Takeaways
- Typical Los Angeles air duct cleaning: $450-$1,100 for most homes.

- Written pricing before work starts, a set arrival window, and the 365-Day Done Right Promise are standard on every Kestrel job.
- Free estimates: call (469) 972-3151.
Air Duct Cleaning Cost Breakdown (2026)
Here’s what the line items actually look like in the Los Angeles market this year. Your written estimate will reflect your home’s specific layout, but this gives you a realistic picture before you dial the number.
| Service Line Item | Typical Los Angeles Price Range |
|---|---|
| Base air duct cleaning (up to 10 vents) | $350 - $550 |
| Additional vents beyond the first 10 | $25 - $45 each |
| Second system or dual-zone home | $175 - $350 additional |
| Main trunk line and plenum cleaning | $150 - $300 |
| Return duct and grille cleaning | $75 - $150 |
| Register and diffuser cleaning (per unit) | $8 - $18 each |
| Dryer vent cleaning (separate service) | $125 - $225 |
| HEPA filtration or IAQ product install (Honeywell, Aprilaire, Guardsman) | $180 - $650 depending on unit |
| Before-and-after video documentation | Included on every Kestrel visit |
What pushes a job toward the top of the range? Long horizontal runs in a slab foundation, a system that’s never been cleaned, heavy dust output, and difficult attic access. What pulls it down? A simple ranch layout, easy crawlspace access, and a single HVAC system with fewer than ten vents. Los Angeles homes are all over the map on this. A 1920s bungalow in Highland Park has short, accessible ducts. A 1990s build in Porter Ranch can have 40 feet of trunk line running through a hot attic with almost nowhere to stand.
One note on the equipment, because it’s the difference between a real cleaning and a glorified vacuum pass. Rotobrush rotary brush systems physically dislodge debris stuck to the duct wall. Nikro negative-pressure units pull loosened contaminants out of the system and hold them there instead of blowing them into your living room. Abatement Technologies HEPA filtration filters the air as the job runs, so fine particles don’t settle back onto your furniture. Every Kestrel technician uses all three. A shop vac from the hardware store doesn’t do any of this.
What Affects Air Duct Cleaning Pricing in Los Angeles
Six things move the price up or down in this market. Knowing them helps you read any quote, ours or someone else’s, with a sharper eye.
- Number of vents and registers. Every supply and return counts. A three-bedroom home in Sherman Oaks typically has 12 to 16 vents. A larger house in Encino can push 20. At $25 to $45 per vent beyond the first ten, this is the single biggest swing factor.
- Number of HVAC systems. Two-story homes with separate upstairs and downstairs units get charged for both. That adds $175 to $350 on average.
- Duct access and layout. Ducts running through a conditioned attic or a crawlspace are straightforward. Ducts buried under insulation, snaked through tight wall cavities, or running long slab runs take more time and more careful equipment work. That time is real cost.
- How long since the last cleaning. A system that hasn’t been touched in 15 years carries more debris, more buildup on the blower, and often more evidence of rodents or pests. It’s not just dirt; it’s the cleanup after it.
- Los Angeles climate and seasonal dust. We deal with wildfire smoke intrusion in the fall, Santa Ana wind events that push fine particulate through every gap in a house, and pollen season that hits the San Fernando Valley hard from February through May. Homes near the Sepulveda Basin and the LA River corridor also pull in more ambient dust year-round. Ducts in this city load up faster than in most markets, which means cleaning cycles come around sooner.
- Whether you bundle dryer vent cleaning. Adding dryer vent cleaning to an air duct visit usually saves $25 to $50 versus booking it separately. It’s a separate service, but the same visit can cover both.
One more factor that doesn’t show up in a quote but should: whether the contractor can actually tell you what’s in your ducts. Before-and-after video documentation lets you see the difference yourself, not take someone’s word for it. We make that standard, not an upgrade. If you want a sense of what a proper job looks like from start to finish, take a look at how we handle air duct cleaning from the first call to the final walkthrough.
How to Save on Air Duct Cleaning
A few genuinely useful things before we get into the FAQs.
- Get the estimate in writing before anyone arrives. A phone quote isn’t a quote. A written estimate with a specific price range and a defined scope is. Any company that won’t put it in writing isn’t worth your time.
- Bundle air duct cleaning with dryer vent cleaning. You already have a technician at the house and equipment set up. Adding the dryer vent as part of the same visit saves $25 to $50 and gets two safety-relevant systems cleaned in one appointment.
- Clean on the right schedule, not the emergency schedule. Most Los Angeles homes should have ducts cleaned every three to five years, sooner if you have pets, allergies, or have been through a wildfire smoke season. Waiting until the system is visibly failing costs more, not less, because the blower and coils usually need attention by then too.
- Ask what filtration you’re running now. A basic fiberglass filter does almost nothing for fine particulate. Upgrading to a proper media filter (Honeywell and Aprilaire both make solid options) extends the time between duct cleanings and takes load off your HVAC system. It’s not air duct cleaning, but it directly affects how often you need it.
- Watch for the door-price revision. If a company quotes you $199 on the phone and revises upward when they see the attic, that’s not an estimate. That’s bait. The written price you receive before the job starts is the price you pay. No exceptions.

FAQs - Air Duct Cleaning Cost
Is $99 air duct cleaning in Los Angeles a real price?
No, and it never has been. A legitimate full-system air duct cleaning in Los Angeles runs $450 to $1,100 for most homes. Companies advertising $99 or $149 will either clean one vent and call it done, or use the low price to get in the door and revise upward once they’re inside. The written price from Kestrel is the price you pay, with no door-step changes. Call (469) 972-3151 for a free, no-pressure estimate.
How much does air duct cleaning cost for a 2,000-square-foot home in Los Angeles?
A 2,000-square-foot Los Angeles home typically runs $600 to $850 for full air duct cleaning, depending on how many vents the system has and whether there’s one HVAC unit or two - compare that to Miami, FL pricing where humidity changes the equation. Homes with a single system and 12 to 14 vents usually come in around $650. If the home has dual systems or long runs through a hot attic, budget closer to $800. The written estimate tells you exactly which side of that range you’re on before any work starts. Call (469) 972-3151 for an exact quote on your address.
Does air duct cleaning actually make a difference, or am I paying for nothing?
It makes a measurable difference in most Los Angeles homes, especially those near wildfire corridors or with pets. What actually changes: airflow improves when the blower isn’t fighting a layer of dust on its blades; indoor particulate drops when the system isn’t recirculating old debris; and your HVAC runs less often because it isn’t working against a clogged return. What doesn’t happen is a magical drop in your allergies on day one. The honest answer is that a duct cleaning removes the source of ongoing particulate, and the improvement shows up over the following weeks. Homes that haven’t been cleaned in 10-plus years see the biggest difference.
Should I clean my ducts before or after I replace my HVAC system?
Clean after the HVAC replacement, not before. A new system installation kicks up debris, disturbs connections, and can leave dust and metal shavings in the ducts. Cleaning first means paying for it twice. Wait until the new equipment is in and running, then schedule the air duct cleaning. The exception is if you’re doing a major renovation; in that case, clean before the renovation to remove existing buildup, then again after the work is done. Call (469) 972-3151 if you want to talk through the timing for your specific project.
How long does air duct cleaning take, and do I need to be home?
Most Los Angeles homes take two to four hours, and yes, you should be home. We want you to see the before-and-after, ask questions about what we found, and walk through the final state with the technician. A typical single-system home runs about two and a half hours. Dual-system homes or homes with long duct runs take three to four. You don’t have to stay in the house the whole time, but we won’t start without you, and we don’t leave until you’ve seen the results. The job is done when you say it’s done, and that’s written into the 365-Day Done Right Promise. Call (469) 972-3151 to schedule.
Why Homeowners Choose Kestrel for Air Duct Cleaning in Los Angeles
Every Kestrel Air Duct Cleaning job runs under the Kingswell Guarantee, and that guarantee is written, not verbal. Four things are promised on every visit: the price before work begins; the arrival window you were given; a clean job site when we leave; and a written guarantee covering the work with a free return visit if something falls short within the guarantee period. That last one is the 365-Day Done Right Promise. If it’s not done right, we come back and make it right, at no charge to you. It’s not a courtesy extended at our discretion. It’s in writing, and it’s been in every job since our founding in 2004 under the Kingswell family of companies.
The technicians who show up at your door are background-checked, uniformed, and trained on Rotobrush, Nikro, and Abatement Technologies equipment. If you want to understand what a proper cleaning actually does to improve your indoor air, start with air duct cleaning and see what the process looks like in detail. And because ducts and dryer vents share the same problem, dust and lint loading up over time, it’s worth pairing the two services on the same visit. Dryer vents in Los Angeles homes are a common fire risk, especially when they run long distances through the wall to an exterior vent. Cleaning them on the same appointment as your air ducts is the practical way to handle both.
We answer the phone with a live person 24/7. Not a queue. Not a bot. When you call, someone real talks to you and books your appointment or gives you a straight range on the spot. The Kingswell Way values govern every visit: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, come back if it fails. Those five things aren’t marketing language. They’re the operating standard.
If you’ve been burned before by a contractor who revised the price at the door, showed up late or not at all, or left before the job was actually finished, that experience is the reason we put everything in writing. Not as a response to the problem. As the way the business has run since the first job.

What Our Customers Say
"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
