The album received mixed reviews from music critics. Giving it a "B+", Jon Freeman of Country Weekly thought that the album contained several "rural tropes" that "wear out their welcome later in the album", but thought that most of the songs were "interesting" for their lyrical content and Farr's "raspy, expressive voice". Giving it 3 out of 5 stars, Stephen Thomas Erlewine of Allmusic wrote that " This inherent politeness does mean his rowdy redneck ways feel a bit like schtick, but it's a good act performed with enough cheer that Farr's slickness sells Redneck Crazy whenever the tunes drift toward the generic." It received 4 out of 5 stars from Matt Bjorke of Roughstock, writing that "strong, likable voice that is put to ample use on the eleven tracks held within and it also suggests there's even more to the man that we've only scratched the surface of."
The album debuted at No. 5 on the Billboard 200 and No. 2 on Billboard's Top Country Albums chart, the highest-charting debut by a new male country artist in two years. It sold 29,000 copies in its debut week. The album has sold 175,300 copies as of February 2015.
