Originally from Parade College, Harford was a Teal Cup captain of Victoria as a youngster.

While at Hawthorn, where he made his debut in 1995, Harford was a hard-at-the-ball midfielder or occasionally, small forward.

In January 2023, Harford was sacked as senior coach after a comprehensive review into the Carlton AFLW Program following a drastic decline in on-field performances.

Notes Harford joined fledgling Melbourne sports radio network SEN 1116 in 2005 as a presenter, after his retirement from the AFL and while he was playing in the VAFA.

In November 2016, Harford resigned from 1116 SEN and moved to RSN 927 to host the breakfast show.
