Air ducts and vents should be cleaned at least every 3 to 5 years, sometimes longer in hot, humid climates such as Florida.

Keeping a house clean, changing HVAC filters regularly, scheduling annual HVAC maintenance, and addressing moisture problems promptly can help keep air ducts cleaner and reduce the need for frequent professional cleaning.
