Duct Cleaning Cost in Southern California (2026)
Honest pricing and an honest answer on when cleaning is worth it
Duct cleaning cost in Southern California runs $495 to $1,295 for a whole-home NADCA-style cleaning, priced by vent count and system count rather than square footage — roughly $35 to $55 per supply register with a minimum charge, plus $95 to $185 for the return and air handler. Sanitizing fog adds $125 to $295. Duct cleaning is genuinely worthwhile after a remodel, after rodent intrusion, after wildfire smoke intrusion, or when registers are visibly furred with dust. It does not fix weak airflow or high bills — those are duct-leakage problems, and duct sealing ($950–$2,850) or replacement ($3,500–$8,500) is the right fix.

Frequently Asked Questions
How much does duct cleaning cost?
$495 to $1,295 for a typical Southern California home, priced by register count. Be skeptical of $89 whole-house coupons — they are almost always a bait price that turns into an upsell on arrival.
Is duct cleaning worth the money?
It is worth it after construction, rodent activity, water intrusion, or wildfire smoke, and when you can see dust mats in the ducts. It is not a fix for weak airflow, uneven rooms, or high electric bills — those are leakage and design problems.
How often should ducts be cleaned?
Every three to five years for most Antelope Valley homes, sooner in high-dust properties, homes with multiple pets, or after any attic rodent issue.
What is the difference between duct cleaning and duct sealing?
Cleaning removes debris from inside the ducts. Sealing closes leaks at joints and boots so conditioned air reaches the rooms instead of the attic. Sealing is what lowers bills — typical duct systems here leak 20 to 30 percent.
Will duct cleaning help my allergies?
It can reduce particulate load, but pairing it with a MERV 11–13 filter or a whole-home media cabinet usually delivers more measurable relief than cleaning alone.
How long does duct cleaning take?
Two to four hours for most homes, longer for two-system houses or when the air handler cabinet and coil need cleaning as well.
