How Much Does Duct Cleaning Cost in Los Angeles?

Professional duct cleaning in Los Angeles typically runs $350-$750 for a standard single-family home, with most homeowners paying around $450-$550 for a complete cleaning of the supply and return ductwork. The job usually takes 3 to 5 hours, and reputable companies will inspect your system first to confirm you actually need the service. At Coldharbour Heating & Air, we give you a written price before any work begins, and that number does not change when we arrive at your door.

Duct Cleaning Cost Breakdown (2026)

Here’s what duct cleaning costs look like across different home sizes and system configurations in the Los Angeles market. These ranges include labor, equipment, and standard disposal fees.

What moves you toward the higher end? Homes in older Los Angeles neighborhoods like Silver Lake, Echo Park, or Mid-Wilshire often have original galvanized ductwork from the 1940s-1960s that’s harder to clean and more likely to need extra attention. Multiple return air locations, a furnace and AC combo system rather than just one or the other, and significant buildup from years without cleaning all add time and cost. The Santa Ana winds blow fine dust through attic vents and crawl spaces in fall and winter, so duct cleaning in Los Angeles often reveals more debris than coastal cities with less seasonal wind exposure.

What Affects Duct Cleaning Pricing in Los Angeles

• Home age and duct material. Pre-1980s homes in neighborhoods like Highland Park or Koreatown frequently have fiberboard or unlined metal ducts that require gentler, slower cleaning methods than modern flexible ductwork.
• Number of vents and returns. A 2-bedroom bungalow in Mar Vista with 8 vents costs less than a 4-bedroom in Encino with 16 vents and multiple return plenums. We count every register before quoting.
• Accessibility. Ducts running through finished basements, tight crawl spaces under pier-and-beam homes, or attics with limited hatch access in older Craftsman builds add labor time.
• Contamination level. Heavy pet hair, visible mold, or construction dust from recent remodeling (common in rapidly gentrifying areas like Frogtown or West Adams) means more passes with the vacuum and agitation tools.
• Additional services. Sanitizing with an EPA-registered product, sealing leaks with mastic or aerosol sealant, or cleaning the evaporator coil and blower assembly are legitimate add-ons that improve air quality but raise the total.
• Company credentials and equipment. Truck-mounted vacuums with HEPA filtration cost more to operate than portable shop vacs, but they actually remove debris instead of redistributing it. We’re trained to service nine major HVAC brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so we understand how your specific system needs to be protected during cleaning.

How to Save on Duct Cleaning

The best way to avoid overpaying is to know what you actually need. Not every home requires annual duct cleaning. The National Air Duct Cleaners Association recommends cleaning every 3 to 5 years under normal conditions, or sooner if you’ve had recent construction, notice visible mold, or see debris blowing from vents.

Here are practical ways to keep costs reasonable:

• Bundle with your tune-up. Scheduling duct cleaning alongside your annual HVAC maintenance (our tune-ups run $95-$235) saves a trip charge and often qualifies for package pricing.
• Check what “cleaning” includes. Some Los Angeles companies quote a low base price but charge extra for every return vent, the main trunk line, or the plenum. Our written price covers the complete system we agree to clean - no surprises at the door.
• Verify you need it. We inspect first. If your ducts are genuinely clean, we’ll tell you. The Kingswell Way means saying the price before the work starts, and that includes being honest when the work isn’t necessary.
• Ask about our 365-Day Done Right Promise. If we clean your ducts and you notice a problem related to our work within a full year, we come back and make it right at no charge. A cheap job that needs redoing costs more than one done correctly the first time.

FAQs - Duct Cleaning Cost

How much does duct cleaning cost for a 2,000-square-foot home in Los Angeles?

$450-$650 is typical for a complete cleaning of supply and return ducts in a 2,000-square-foot Los Angeles home with a standard forced-air system. Homes in wind-exposed hillsides or with older ductwork may run toward the higher end. Call (817) 402-2972 for a free estimate tailored to your specific layout.

Is it cheaper to repair or replace my ducts instead of cleaning them?

Repairing isolated damage costs $150-$500 per section, while full duct replacement runs $2,000-$6,000 in Los Angeles. Cleaning is the economical choice when ducts are structurally sound but dirty. We inspect first and show you what we find - if sections are crushed, disconnected, or deteriorated, we’ll explain whether repair, replacement, or cleaning makes financial sense.

Can you come today for duct cleaning?

Same-day service is often available because our phones are answered by a live person 24 hours a day, 7 days a week. Duct cleaning requires a 3-to-5-hour window, so we may schedule next-day if today’s slots are full. Call (817) 402-2972 and we’ll find the earliest opening that works for your schedule.

Why do some Los Angeles companies charge $99 for duct cleaning?

$99 duct cleaning is almost always a bait-and-switch tactic. The advertised price covers minimal work, and technicians upsell aggressively once inside your home. Reputable cleaning with proper truck-mounted equipment, HEPA filtration, and trained technicians cannot be performed at that price point. Our written price is the price you pay - this is a core plank of The Kingswell Way.

Does duct cleaning actually lower my energy bills?

Modest savings of 5-15% are possible if your ducts were severely clogged, but the primary benefits are improved indoor air quality, reduced allergens, and less strain on your blower motor. In Los Angeles, where we run AC heavily from May through October, clean ducts help your system maintain airflow without overworking. The real value is protecting your HVAC investment and breathing cleaner air, not dramatic bill reduction.
