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?
Air duct cleaning in Los Angeles typically runs $350 to $900 for a standard single-family home, with most jobs landing around $500. Larger homes in the hills, older properties with original ductwork, and systems that haven’t been touched in a decade push toward the upper end. If you’ve been quoted $99 by a coupon, that price is for one vent, not your house. We write the real number down before we start, and it doesn’t change once we’re inside.
Below is a full 2026 price guide for the Los Angeles market. These are the ranges we work with every day. Use them to compare bids and to spot a lowball offer before you book it.
Key Takeaways
- Typical Los Angeles home: $350 – $900, average around $500.
- Pricing is driven by the number of vents, system size, accessibility, and how much debris has built up.
- Always get the price in writing before any work starts. A quote that moves at the door is a red flag.
- Hollis covers every job under the 365-Day Done Right Promise: if the work fails within a year, we return and make it right at no charge.
- Estimates are free. Call (361) 326-5060 and talk to a live person, any hour.
Air Duct Cleaning Cost Breakdown (2026)
These are line-item ranges for Los Angeles work in 2026. Your actual price depends on how many vents you have and how easy it is to reach the trunk lines. We quote a flat rate after a walkthrough, not a per-vent add-on that climbs as the technician counts.
| Service | Typical Range | Notes |
|---|---|---|
| Standard single-family home (1 system, up to 10 vents) | $350 – $550 | Most common Los Angeles job |
| Larger home (2 systems or 11 – 20 vents) | $550 – $900 | Common in the Valley and hillside homes |
| Per additional vent beyond 20 | $15 – $30 each | Adds up fast in big two-story homes |
| Heavy debris removal (rodent nesting, construction dust) | $150 – $400 add-on | Common after remodels |
| Dryer vent cleaning | $130 – $250 | Often bundled at a discount |
| Duct sealing (mastic, per system) | $400 – $900 | Prices vary with how much access is needed |
| Sanitizing / fogging treatment | $150 – $350 | Optional, often after mold or pest issues |
The single biggest driver of price is the number of vents and how many separate air systems your house runs. A 1,400-square-foot bungalow in Highland Park with one furnace and eight vents is a very different job from a 3,200-square-foot house in Encino running two systems and eighteen vents. The second driver is access. Ductwork buried behind a low attic crawlspace or a finished ceiling takes more time to reach, and time is what you’re paying for.
Third is condition. A system cleaned three years ago comes apart easier than one that’s been sitting for fifteen. And in Los Angeles specifically, wildfire seasons push ash and fine particulate into return ducts across wide swaths of the city. After a bad smoke year, we see far more residue loaded into the return side than a typical cleaning year. If your home sat through a heavy fire season with the windows open, expect to land in the middle or upper half of the range.

What Affects Air Duct Cleaning Pricing in Los Angeles
- Number of vents and systems. Each supply and return vent adds time and equipment passes. Two systems roughly doubles the labor versus one.
- Accessibility of the ductwork. Attic and crawlspace layouts vary block to block. A low, hot attic in the Valley summer means slower, more careful work than a tall open one.
- Level of contamination. Fine ash from wildfire season, construction dust from a kitchen remodel, or rodent debris in the ducts all require more passes and, sometimes, negative-air containment from Nikro equipment to keep the mess out of your living space.
- Duct material and age. Older rigid metal ductwork cleans differently than flexible insulated runs. Homes built before the 1980s often have duct configurations that take longer to reach.
- Add-on services. Duct sealing, sanitizing, and dryer vent cleaning add to the base price, though bundling usually saves money versus booking each separately.
- Time of year. Summer and fall, when systems run hardest and wildfire smoke is a factor, is our busiest window. Booking mid-week in spring often means more flexible scheduling at the same written price.
One thing that does not affect our price: whether you’re in Santa Monica or Sherman Oaks. We price the job, not the zip code. A written quote in Los Angeles is the same number whether you call from a condo near the coast or a house in the hills.
How to Save on Air Duct Cleaning
You don’t get a lower real price by chasing the lowest advertised number. You get it by asking the right questions and booking smart. Here’s what actually works.
- Bundle services in one visit. Combining duct cleaning with dryer vent cleaning or duct sealing spreads the trip cost across more work. We discount bundled jobs because we’re already on site with the equipment set up.
- Book in the off-season. Late winter and early spring are quieter for us. The price is written the same, but you’ll have an easier time picking your window.
- Know your vent count before you call. Walk your home and count the supply and return registers. It takes five minutes and gives you an accurate quote on the first call instead of a surprise adjustment later.
- Get the price in writing, always. This is the single best way to avoid paying more than you agreed. If a company won’t put the number in writing before work starts, that’s your answer.
- Ask what’s covered if the work fails. A written guarantee is worth more than a discount. Our 365-Day Done Right Promise means if the cleaning or sealing fails within a year, we come back and fix it at no charge, including a free second visit.
Estimates are free and there’s no pressure to book. Call (361) 326-5060 and we’ll give you a straight number for your home over the phone once you’ve got your vent count.
Understanding What You’re Paying For
Air duct cleaning isn’t a mystery box. What you pay for is equipment, time, and method. The crews using hardware-store vacuums and a shop vac hose are charging less because they’re doing less. Here’s what a real job includes and why it costs what it costs.
We use a rotary brush system from Rotobrush to scrub the interior walls of the ductwork, dislodging the caked-on layer that a vacuum alone won’t touch. We pair that with Nikro negative-air machines, which pull the loosened debris out of the system while keeping it from blowing back into your rooms. For filtration, we work with products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. If your filters and returns are pulling in fine Los Angeles ash, the right filtration media matters as much as the cleaning itself. Each of these tools is explained to you in plain terms on the job, so you know what’s running in your home and why.
What you’re also paying for is somebody who shows up. Technicians are background-checked and uniformed. You know who’s coming before they arrive. Phones are answered by a live person 24 hours a day, seven days a week, so you’re not leaving a voicemail on a Friday and hoping somebody calls back Monday. Every job follows The Garrison Standard: arrive inside the quoted window, price in writing, work done by the book, site left clean. Those are the operational specifics you’re buying, not adjectives.
When to Clean Your Ducts (and When to Wait)
Not every home needs cleaning every year. Knowing when yours does saves money and tells you whether a quote is even necessary right now.
- Visible dust blowing from registers shortly after you’ve cleaned a room.
- After a remodel or major renovation, when drywall dust and debris settle into the returns.
- After wildfire season if your home took in smoke or ash, especially with windows open.
- New home purchase, when you don’t know the previous owner’s maintenance history.
- Signs of pests, like rodent droppings or nesting material near vents.
- Persistent musty odors when the system runs, which can point to moisture or microbial growth.
If none of those apply and your system isn’t running unusually, you can likely wait. We’d rather tell you that than sell you a cleaning you don’t need. That’s part of pricing in good faith. If the answer is that you do need it, a proper cleaning also supports the health of the whole system, which ties directly into how well your home heating and cooling performs.
Why Low-Cost Air Duct Cleaning Quotes Cost More Than They Save
A $99 air duct cleaning in Atlanta, GA is rarely a $99 air duct cleaning. That figure usually buys one vent, one system, or a single pass, and everything else is an add-on the technician pitches once he’s standing in your hallway. The price the deal advertised is the price to get in the door. By the time you’re done, you can end up paying more than a straight quote from a company that priced the whole job up front.
The other problem is what a cut-rate job leaves behind. A partial cleaning can loosen debris that never gets fully extracted, and a few weeks later you’re seeing more dust than before you called. That costs you a second cleaning to fix the first one. When we quote a Los Angeles home, the number covers the whole system, and it’s written down before we touch anything. If our work fails inside a year, the 365-Day Done Right Promise means we return at no charge. That’s what an honest price includes, and it’s why competing on a teaser number isn’t how we run the business.
FAQs About Air Duct Cleaning Cost in Los Angeles
How much does air duct cleaning cost in Los Angeles?
Most Los Angeles homes pay $350 to $900, with an average around $500. A single-system home with up to ten vents sits at the low end, while two-system homes and larger properties with heavy debris land higher. Call (361) 326-5060 for an exact quote for your house. Estimates are free.
How many vents does my home have, and does it matter for price?
Vent count is the biggest single factor in your price, and most homes have between eight and twenty supply and return registers. Count them before you call and you’ll get a tighter quote on the first conversation. Beyond twenty vents, expect roughly $15 to $30 per additional vent.
Is it cheaper to clean the ducts or seal them?
Cleaning in Austin, TX ($350 – $900) is usually the cheaper of the two, while duct sealing runs $400 – $900 per system. They solve different problems: cleaning removes built-up debris, sealing closes leaks that waste conditioned air. Many Los Angeles homes benefit from both, and bundling them in one visit costs less than booking each separately. Call (361) 326-5060 to find out which your home needs.
How long does air duct cleaning take, and does that affect the price?
A standard single-system Los Angeles home takes two to four hours, and larger two-system homes can run five to six. Time is built into the flat price you’re quoted, so a longer job doesn’t mean a higher bill than the number we wrote down. You’ll know the duration before we start.
Can you come today, and will the price change?
Same-day availability is often possible, and the written price is the same whether we arrive today or next week. No rush fee, no door-step increase. Call (361) 326-5060 and a live person will tell you the soonest window we have and the price for your home before you commit to anything.
What’s covered if the cleaning doesn’t hold up?
Every job is covered by the 365-Day Done Right Promise. If the work fails within a year, we come back and make it right at no charge, including a free second visit. That coverage is in writing, not a verbal promise, and it’s the reason we can price a job once and stand behind it.
