AfterHow Much Does Duct Cleaning Cost in Los Angeles?
Duct cleaning in Los Angeles typically runs $350 to $900 for a standard single-family home, with most jobs landing around $500. Larger homes, two-story layouts, and heavy buildup from wildfire smoke or years of neglect push the price higher. A single-vent or condo job can come in closer to $250.
That range covers a full system: supply and return ducts, registers, and the main trunk lines. What it does not cover is the air handler itself, which we clean as part of an AC maintenance visit rather than a duct-only service. If you want the whole picture of how your HVAC system is priced in this market, our home page walks through it.
You should never hear a duct cleaning price for the first time after the work is done. Every Brandt HVAC job starts with a written price you read and agree to before anyone touches a screwdriver. That’s not a marketing line, it’s how we run every call.
Duct Cleaning Cost Breakdown (2026)
Here’s what Los Angeles homeowners actually pay, broken out by the pieces of the job. These are real ranges for this market, not national averages pulled from a blog.
| Service | Typical Price Range |
|---|---|
| Standard whole-home duct cleaning (10-15 vents) | $350 – $650 |
| Larger home (16-25 vents, second story) | $650 – $900 |
| Condo or single-vent cleaning | $250 – $400 |
| Return duct and main trunk line cleaning | $150 – $300 |
| Dryer vent cleaning (add-on) | $100 – $175 |
| Register and grille cleaning (per unit) | $8 – $15 |
| Mold remediation in ducts (per affected section) | $400 – $1,200 |
| Post-wildfire smoke and ash removal | $500 – $1,100 |
Three things move the price: the size of your system, how much debris is inside it, and whether anything unusual is growing or nesting in there. A 1,200-square-foot bungalow in Highland Park with 10 vents is a different job than a 3,000-square-foot two-story in Sherman Oaks with 22 vents and a return line that hasn’t been touched since the house was built.
What Affects Duct Cleaning Pricing in Los Angeles
- Number of vents and returns. Most companies price per vent plus a base fee. A home with 12 vents sits at the low end; 22 vents can nearly double the base. Ask for the per-vent rate before you book so the math is clear.
- Access and attic conditions. In older Los Angeles neighborhoods like Echo Park and Silver Lake, ductwork often snakes through tight, low-clearance attics and crawlspaces. Hard-to-reach runs take longer and cost more.
- Wildfire smoke and ash. After a major fire season, we see duct systems across the San Fernando Valley and the foothill communities loaded with fine ash that settles deep into the flex duct. That’s a bigger job than routine dust and typically adds $150 to $400.
- Mold and moisture. Coastal homes near Santa Monica and Venice run into condensation problems in ductwork more often than inland homes. Any mold found during inspection has to be treated and documented, which raises the price.
- Pest debris. Rodents and birds find their way into attic duct runs, and their nests and droppings require careful removal and sometimes duct replacement. This is one of the most common reasons a quote comes in higher than expected.
- Duct material and age. Rigid metal ducts clean faster and hold up better than old flex duct. If your ductwork is deteriorating, cleaning may not be the right fix at all, and we’ll tell you that straight.
One more local factor: Los Angeles has some of the most varied housing stock in the country. A 1920s Craftsman, a 1970s ranch in Woodland Hills, and a new build in Playa Vista all have different duct systems. That’s why we inspect first and quote second.
What You Actually Get for the Price
Price only means something if you know what’s included. Here’s what a full duct cleaning job covers when it’s done right:
- Inspection first. We look inside the ducts with a camera before quoting. You see what we see.
- Written price. Before any equipment comes off the truck, you get the number in writing. No surprises at the end.
- Source removal. We use truck-mounted or portable negative-air equipment so debris is pulled out of your home, not blown into the living room.
- Supply, return, and trunk lines. All three, not just the easy-to-reach supply vents.
- Register and grille cleaning. Every vent cover pulled, cleaned, and put back.
- Post-job photos. We show you before-and-after images of the duct interior.
- Written guarantee. Every repair we make carries a written guarantee, and if something fails within that period we come back at no charge under the 365-Day Done Right Promise.
Brandt comes from an old word for a firebrand, which fits the work of keeping a home warm and the air in it clean. We’ve been part of the Threshold Group family of home-service companies since 2003, and every location is independently owned and operated.

How to Save on Duct Cleaning
There’s no secret coupon code. But a few practical moves keep the price down:
- Bundle it with a tune-up. If you’re already scheduling AC maintenance, adding duct cleaning to the same visit saves you a separate trip charge. Most tune-ups run $95 to $235.
- Clean your filters monthly. A clogged filter lets more dust into the ducts. Changing it every 30 days during heavy-use months is the cheapest duct protection there is.
- Don’t wait for a crisis. Addressing dust early costs less than dealing with mold or pest debris later.
- Get the written estimate before you commit. Free estimates exist, and you should never pay for one.
- Ask about per-vent pricing. It lets you decide whether to do the whole house now or the main living areas first.

FAQs – Duct Cleaning Cost
How much does duct cleaning cost in Los Angeles?
Most Los Angeles homeowners pay $350 to $900, with a typical job around $500 for a standard single-family home. Condos and smaller jobs start near $250. Call (984) 538-9003 for an exact quote on your home, and estimates are free.
Is duct cleaning worth the money?
Yes, when there’s a real reason for it. If you’ve had water damage, a pest problem, recent wildfire smoke, or visible dust blowing from your vents, cleaning typically pays off in better air quality and a system that doesn’t strain. If your ducts are clean and your filter is doing its job, we’ll tell you so and save you the money.
How long does duct cleaning take?
A standard home takes 2 to 4 hours. Larger homes or post-wildfire jobs can run 4 to 6 hours. We give you a time window when you book and stick to it.
How often should ducts be cleaned?
Every 3 to 5 years for most homes. In Los Angeles, if you live near wildfire zones or have pets, closer to every 3 years. Homes with allergy sufferers often benefit from more frequent cleaning.
Who will come to my house, and how do I know they’re safe?
You’ll know exactly who’s coming. Every Brandt technician is background-checked and identity-verified through the Threshold Verified standard. You get their name and photo before the visit, and they show a photo ID badge at the door. If anyone arrives who you weren’t told to expect, that visit is on us and we make it right. A live person answers the phone 24/7 if you have questions before or after the appointment.
