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.

Air Duct Cleaning Cost Breakdown (2026)
Here’s what LA homeowners actually pay, line by line. These prices reflect the Los Angeles market as of 2026 and assume a typical 1,800 to 2,500 square foot home with a single HVAC system.
| Service | Typical LA Price | Notes |
|---|---|---|
| Standard single-system duct cleaning | $350 – $650 | Up to 12 vents, one air handler |
| Larger home (2,500 – 3,500 sq ft) | $550 – $850 | More vents, longer runs |
| Multi-zone / dual-system home | $700 – $1,200 | Second air handler adds cost |
| Return duct cleaning (large runs) | $100 – $250 | Often the dirtiest part of the system |
| Dryer vent cleaning | $125 – $250 | Bundled discount when added to duct cleaning |
| Negative-pressure containment setup | Included | Keeps debris out of your living space |
| Before-and-after photo documentation | Included | Standard on every booking |
| Antimicrobial fogging (optional) | $75 – $200 | Only if you have visible microbial growth |
Negative-pressure extraction is the setup that keeps loosened debris moving into our Nikro HEPA vacuum instead of back into your living room. It’s not an upsell; it’s how a professional job is supposed to work. Cheaper quotes that skip containment are often the reason homeowners find dust on the furniture afterward.
What pushes your How Much Does Air Duct Cleaning Cost in Arlington, TX? (2026 Price Guide) number up: extra systems, more vents, flex duct that requires slower brush passes, and heavy buildup in return runs. What keeps it down: a smaller home, recent cleaning, and bundling dryer vent work into the same visit.
What Affects Air Duct Cleaning Pricing in Los Angeles
LA isn’t a generic market. The air here is different, the housing stock is different, and the pricing reflects both. Here’s what genuinely moves the number.
- Number of HVAC systems. A single-family home in the San Fernando Valley with one system sits at the low end. A two-story house in Encino or Sherman Oaks with dual-zone climate control commonly lands $800 or higher because there’s a second air handler and a second set of ducts to clean.
- Vent and register count. Most LA homes we see in neighborhoods like Mid-City, Culver City, and Highland Park run 14 to 22 vents. Each register adds a few minutes of brush work and a few dollars to the total. Homes over 20 vents often cross the $700 mark.
- Duct material. Rigid sheet-metal ductwork cleans fast. Flex duct – the coiled, plastic-wrapped tube common in 1990s tract homes across the Valley – requires gentler brush pressure and more passes, which adds labor. Crushed or kinked flex runs can’t be fully cleaned without repair.
- Buildup from LA’s specific air. We regularly pull dense grey dust out of ducts in homes near the I-10, the 405, and the 101. In places like Boyle Heights and West Adams, that road dust combines with seasonal pollen from sycamores and olive trees, and the buildup is heavier than what you’d find in a coastal home.
- Pet dander and occupancy. Homes with two or more shedding pets often need a slower, more thorough pass and occasionally a second HEPA pass. That’s labor, and it shows up in the price.
- Access difficulty. Ducts buried behind finished ceilings, in tight attic runs, or in older Craftsman homes with irregular framing take longer. An accessible attic run in a Van Nuys ranch house is a very different job than a duct maze under a 1920s bungalow in Angelino Heights.
One thing you’ll notice: How Much Does Air Duct Cleaning Cost in Atlanta, GA? (2026 Price Guide) LA pricing runs slightly above the national average. Not because we’re padding it, but because labor costs, parking logistics, and drive time between neighborhoods like Santa Monica and Pasadena are real expenses. When you book with us, those factors are baked into the written price you get up front.
What’s Actually Included at That Price
Price means nothing without knowing what’s in the truck. Here’s what every Cardinal Air Duct Cleaning job includes, regardless of which end of the range you fall on.
- Rotobrush rotary brush cleaning for the duct walls. The brush spins inside the duct and physically scrubs material off, rather than just blowing air through.
- Nikro HEPA vacuum extraction pulling everything loosened into a sealed filtration system.
- Abatement Technologies containment so your living room doesn’t become a dust cloud during the job.
- Air handler and coil inspection – we look at the blower, evaporator coil, and drain pan and tell you what we see.
- Before-and-after photos of the actual ducts we cleaned, sent to your phone. Not stock images.
- A written price before any work starts. Not a verbal estimate. Not “we’ll see once we open it up.”
- The 365-Day Done Right Promise. If the work isn’t right within 365 days, we return and correct it at no charge.
That’s the whole standard. No mystery tiers, no “premium package” upsell that just means a longer sales script. If you want the fuller picture on what we do and how the service works, our Air Duct Cleaning in Los Angeles page walks through it.
How to Save on Air Duct Cleaning
A few practical ways to keep the How Much Does Air Duct Cleaning Cost in Austin, TX? (2026 Price Guide) number on the lower end without cutting corners.
- Bundle dryer vent cleaning. Adding it to a duct cleaning visit typically saves $50 to $100 versus booking it separately. It’s also the single best fire-safety move you can make on an LA home with a long dryer run.
- Book a multi-home discount. If you’re a landlord with a duplex in Koreatown or a small portfolio in the Valley, we can quote multiple units on one visit and the per-unit price drops. Call (737) 727-2314 and we’ll work out the numbers.
- Skip the antimicrobial fog if you don’t need it. It’s a real service, but it’s for homes with visible microbial growth, water damage history, or a musty smell that persists after cleaning. If you don’t have those, decline it. We’ll tell you honestly whether you need it.
- Change your filter first. A clogged filter means more dust circulating and a dirtier system. Replacing it before we arrive, then maintaining it, stretches the interval between cleanings.
- Get the free estimate before you commit. Every Cardinal quote is free, and it’s in writing. No deposit, no pressure, no “today only” pricing games.
One more: don’t chase the lowest number on a search results page. In LA, sub-$200 duct cleaning quotes almost always mean a truck-mounted shop vac and a technician who runs it up to your nearest register for 20 minutes. That’s not duct cleaning. It’s a vacuum with a marketing budget.
Is It Cheaper to Repair or Replace Your Ducts?
The answer depends on what’s wrong. Cleaning is always cheaper than repair, and repair is almost always cheaper than replacement. A standard cleaning at $350 to $850 is the low-cost option. Targeted duct repair, where we seal specific leaks or reconnect a few disconnected runs, typically runs $250 to $600 on top of the cleaning. Full duct replacement, which we only recommend when ductwork is crushed, contaminated with mold, or failing in multiple sections, commonly runs $2,000 to $6,000 depending on home size and duct accessibility.
The honest rule: if your ducts are intact, you clean them. If they’re leaking 20 to 30 percent of your conditioned air (common in older LA homes), you repair them. If they’re structurally failing or water-damaged, you replace. We tell you which one you’re looking at, with photos, before quoting anything.

FAQs – Air Duct Cleaning Cost in Los Angeles
How much does air duct cleaning cost in Los Angeles?
Most LA homeowners pay $350 to $850, with a typical single-family home landing around $500. Larger or multi-zone homes run $700 to $1,200. Call (737) 727-2314 for an exact quote – estimates are free and there’s no obligation.
Can you clean my ducts the same day?
Often, yes. We keep same-day and next-day slots open across Los Angeles, and yes, a live person answers the phone 24/7 – no voicemail loop. When you book, you get a live trackable arrival window, so you’re not sitting around for four hours wondering when someone will show up. For a faster booking, call (737) 727-2314 and we’ll tell you what’s available.
Do I need duct cleaning if I change my filter regularly?
Filter changes help, but they don’t clean the duct walls. Most LA homes benefit from a cleaning every 3 to 5 years, and homes with pets, recent remodeling, or proximity to freeways like the 405 or the 10 often need a shorter interval. If you’ve recently remodeled a kitchen or bathroom, drywall dust gets pulled into the system fast – that alone is a reason to book. Call (737) 727-2314 and we’ll help you decide.
Is it worth getting duct cleaning for $99 or $149 from another company?
No. In Los Angeles, a $99 duct cleaning is almost always a bait-and-switch or a shop-vac pass that doesn’t touch the duct walls. A legitimate cleaning requires rotary brush equipment, HEPA extraction, and containment, which costs real money to run. Our entry point is $350, and the difference buys you a documented, photographed, guaranteed job. Call (737) 727-2314 if you’d like us to walk you through what we actually do for that price.
Does duct cleaning lower my energy bill in LA?
It can, but we won’t oversell it. Cleaned ducts improve airflow, which lets your HVAC system run less to reach the same comfort level. In an LA home running AC from May through October, homeowners often report 5 to 15 percent lower cooling costs after a cleaning, especially in older homes with leaky ductwork. That’s meaningful, not transformative – but combined with our 365-Day Done Right Promise, it’s a real improvement you can see in your next bill.
What exactly is the 365-Day Done Right Promise?
It’s simple: if the work isn’t right within 365 days, we come back and make it right at no charge. Every booking. No exceptions. Every repair also gets a written guarantee plus a free second visit if the repair fails. This is the longest-standing satisfaction window in the trade, and it’s the reason we can quote a clear price up front and stand behind it.
