Quick answer: Duct cleaning should be based on the condition of the system, not an automatic annual schedule.
Understanding the issue
Duct cleaning should be based on the condition of the system, not an automatic annual schedule. EPA identifies substantial contamination, pests, or excessive debris as reasons to consider it. Ordinary dust on a return grille does not prove the entire duct system needs cleaning.
What homeowners can do
Ask to see evidence supporting a cleaning recommendation. If moisture or another problem is causing contamination, that cause needs attention too. Cleaning should not be advertised as a guaranteed cure for allergies or other health problems.
