When he was six years old, his parents moved the family to Nashua, New Hampshire. Crombie was educated at Pinkerton Academy in Derry, New Hampshire, and at Nashua High School.

After becoming a resident of Burlington, Crombie began a career in the lumber business as an employee of L. Barnes & Co. a company owned by Lawrence Barnes, who also operated several other prominent Burlington enterprises. In 1869, Barnes sold L. Barnes & Co. to the owners of a new venture, Shepard, Davis & Company, where Crombie continued to work.

He was nominated unanimously by Burlington's Republican Party and in the general election he defeated Democratic nominee Seneca Haselton by 1126 votes (61.5%) to 705 (38.5%).
