Hands-on homeowners may be prompted to attempt cleaning their own ducts. Some do so without really thinking about the implications. It may be easy to see dirt buildup on registers and inside the openings of vents. Operating a vacuum cleaner to remove debris makes a lot of sense at this point, but the effort provides limited results and can cause damage to your ducts. A vacuum extension is limited in its reach, and the implement could puncture your duct walls if you aren’t careful.
