Could also be a breaker issue. We (as an electrical contractor) have seen very sensitive AFCI breakers (typically when combined with GFCI protection). I would suggest installing a standard breaker and add a faceless AFCI receptacle
[Link: leviton.com] at the panel. This will still meet the code requirement but bypass the sensitive breaker.
Do AFCI still trip easily when a vacuum cleaner is used on those circuits and is the requirement to replace as soon as they trip?
