AfterSupply Duct Cleaning in Los Angeles, CA
Supply duct cleaning in Los Angeles typically costs between $350 and $700 for an average 2,000-square-foot home, and most jobs are completed in 3 to 5 hours. Supply ducts are the network of metal or flex tubes that carry conditioned air from your furnace or air handler out to the vents in each room. When those ducts are lined with years of dust, pet dander, and construction debris, every cooled or heated breath of air in your home passes through it first.
At Kestrel Air Duct Los Angeles, we clean supply ducts with professional-grade negative-air extraction equipment and rotary brush systems. That means we dislodge debris at the duct wall with a powered brush, then pull it out of your home under negative pressure so it doesn’t end up on your couch or in your lungs. If you’re looking at a broader air quality project, see our Air Duct Cleaning page for the full system approach. For questions or to schedule a visit, call us at (213) 733-0665.
Dale Whitmore has run this location under the Kingswell Guarantee since 2004, and every supply duct job starts with a written price in your hand before a single vent is opened.
When You Need Supply Duct Cleaning
Supply ducts don’t usually announce themselves. The signs are subtle at first, then impossible to ignore. Here’s what we hear from homeowners across Los Angeles when they call us:
- Dust returns within days of housekeeping. You wipe down a dresser on Monday and by Thursday it has a fine gray film again. That dust is being pushed out of your supply registers every time the blower runs.
- Airflow is weak in specific rooms. One bedroom stays muggy in August no matter how low you set the thermostat. A partial blockage in that room’s supply run is often the cause, and in older Los Angeles homes with decades-old galvanized ductwork, it’s common.
- You renovated or purchased recently. Drywall dust, sawdust, and paint overspray get pulled into return and supply ducts during construction. New purchases in neighborhoods like Silver Lake or Mid-City often have original ductwork that hasn’t been touched since the house was built.
- Allergy symptoms flare at home but ease when you leave. If you feel better at the office or outdoors and worse in your living room, you’re likely breathing contaminants distributed through supply ducts.
- You see debris around supply registers. Dark streaks or visible dust clumps on the ceiling or wall around a supply vent mean the duct behind it is loaded and shedding into living space.
- Energy bills climb without explanation. A heavy dust layer on duct walls restricts airflow and makes your HVAC system work harder, especially during hot Los Angeles summers when the air handler runs for hours daily.
If two or more of these sound familiar, supply duct cleaning is likely overdue. Call (213) 733-0665 and we’ll give you an honest assessment over the phone before scheduling anything.
Our Supply Duct Cleaning Process
We follow the same sequence on every job, starting with a Video Inspection, because it’s the one that produces verifiable results. Here’s what happens when our crew arrives at your Los Angeles home:
- Walkthrough and written quote. Dale or a senior technician inspects your supply registers, checks access points near the air handler, and gives you a written price before any equipment comes off the truck. The Kingswell Way says the price doesn’t change after this point, and it doesn’t.
- Protection and containment. We lay corner guards and drop cloths along the path from entry to the mechanical room. Supply registers are sealed off temporarily so loosened debris can’t recirculate into the house while we work.
- Rotary brush agitation. We run a Rotobrush system through each supply run. The rotating brushes scrub the duct walls to break up caked-on dust, pet hair, and debris that a vacuum alone can’t remove. Brush agitation means physically scrubbing the inside of the duct, not just waving a hose around.
- Negative-air extraction. A Nikro negative-pressure unit connects to the main supply trunk and pulls the dislodged debris out of the ducts and into a sealed filtration system. Negative-air extraction means the system creates suction that draws air and contaminants out of the duct rather than blowing them around, so what we loosen gets removed, not redistributed.
- Post-clean inspection. After cleaning, we run a camera through representative supply runs to confirm the walls are clean and there are no disconnected joints or damage we need to flag for you.
- Written documentation. You get a summary of what we did, what we found, and a written copy of the 365-Day Done Right Promise. If something’s not right within a year, we come back at no charge.
Our technicians are background-checked, uniformed, and trained on the same equipment they carry. We use Abatement Technologies HEPA filtration on select jobs where particulate control is critical, typically when homeowners have severe allergies or respiratory conditions.
Supply Duct Cleaning Pricing in Los Angeles
Most supply duct cleaning jobs in Los Angeles run between $350 and $700. Small apartments or condos with fewer than 8 supply runs may come in lower, while larger homes with complex duct layouts, multiple HVAC zones, or significant buildup can exceed that range. We quote it in writing before we start, so you’ll know your number before deciding to proceed.
Here’s how the cost typically breaks down for a Los Angeles single-family home:
- Small home or condo (up to 8 supply runs): $300 – $450
- Average 3-bedroom home (9 – 14 supply runs): $450 – $650
- Larger home or multi-zone system (15+ supply runs): $650 – $900
- Access challenges (tight crawlspace, rooftop unit, long flex runs): adds $75 – $150 depending on complexity
- Post-renovation heavy buildup: may increase labor time and final quote, always disclosed in writing upfront
What affects the price most is the number of supply runs and how accessible the ductwork is. Los Angeles homes span a wide range, from 1920s bungalows with original sheet metal ducts to mid-century ranches with hard-to-reach crawlspaces to newer builds with insulated flex runs. Each layout takes a different amount of time to clean properly.

FAQs – Supply Duct Cleaning
How much does supply duct cleaning cost in Los Angeles?
Supply duct cleaning in Los Angeles typically costs between $350 and $700 for most single-family homes, depending on the number of supply runs and access difficulty; our How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Los Angeles, CA explains the factors in detail. We provide a written quote before starting any work so the price you sign off on is the price you pay. For an exact number on your home, call (213) 733-0665 for a free estimate.
Is supply duct cleaning worth the money?
If your supply ducts haven’t been cleaned in 10 or more years, the dust, pet dander, and debris buildup in them recirculates through every room every time the HVAC runs, which can worsen allergies and settle on surfaces within days. Homeowners who get their ducts cleaned typically notice less dust accumulation and improved airflow in weak rooms right away. The value depends on your duct condition, which we assess honestly during the walkthrough.
Can you clean supply ducts the same day?
Yes, we often accommodate same-day or next-day supply duct cleaning in Los Angeles, especially when a homeowner discovers the issue during a weekend or before hosting guests. Our calls are answered by a live person around the clock, so you’ll know immediately what our schedule looks like. Call (213) 733-0665 and ask.
Does supply duct cleaning help with allergies in Los Angeles?
Supply duct cleaning removes the accumulated dust, pollen, and pet dander that your HVAC system distributes through the house, which can reduce the airborne particles allergy sufferers react to. Homes near busy Los Angeles thoroughfares or with older ductwork often carry significant particulate buildup. For ongoing filtration between cleanings, we can also discuss options like Honeywell or Aprilaire media filters with you.
What’s the difference between supply duct cleaning and full air duct cleaning?
Supply duct cleaning focuses exclusively on the ducts that deliver conditioned air from your air handler to each room, while full Air Duct Cleaning also covers return ducts, the main trunk line, and other components of the system. Most homeowners benefit from cleaning the whole system at once, but we’ll quote supply-only work if that’s what your situation calls for.
Why Los Angeles Homeowners Choose Kestrel for Supply Duct Work
The company started under the Kingswell Guarantee in 2004 with a simple idea: say the price, show up in the window given, leave the place cleaner, put the guarantee in writing, and come back if the work fails. Those aren’t promises we gesture at. They’re written on every invoice we issue.
Dale Whitmore has built this Los Angeles location on that code, and it runs through every technician who walks through your door. If a supply duct cleaning job doesn’t hold up within 365 days, we return and make it right at no charge. You don’t argue about it. You point to the written guarantee, and we schedule the return visit.
We answer the phone with a live person at any hour. Not an answering service that takes a message. A person who can talk through your symptoms, give you a realistic expectation, and get you on the schedule. If you’ve been burned by a no-show air duct contractor before, that’s the difference you notice first.
Ready to get the dust out of your supply ducts? Call (213) 733-0665 for a free estimate. You’ll get a straight answer and a written price before any work begins. That’s the Kestrel way.
