Air-duct cleaning
Canonical HVACentric knowledge for residential questions on this topic.
DIRECT ANSWER
Routine duct cleaning is not automatically necessary for every home. First identify the reason being considered, such as substantial visible contamination, debris release, pest activity, moisture damage, or a specific obstruction. Correct moisture or pest sources before cleaning. Ask what portions of the system will be cleaned, how the building will be protected, and what evidence supports any health or energy claim.
