Frehley graduated Grace Lutheran School at age 13. However, he was thrown out of two high schools and dropped out of the third. It was in his high school years that he got the nickname Ace when he had the ability to get his friends dates.

Frehley spent the early 1970s in a series of local bands. In late 1972, he and his best friend, Bob McAdams autidioned for a band named Wicked Lester and by January 1973 the band decided on a new name – Kiss. Kiss released their debut album, Kiss, in February 1974—Frehley's sole songwriting contribution was Cold Gin. Along with the three other Kiss members, Frehley released an eponymous solo album in 1978. His was the best-selling of the four. In December 1982, Kiss began the Creatures of the Night tour without Frehley. However, Frehley retained a one-quarter share in the Kiss partnership until 1985.

In 1984, Frehley started his post-Kiss solo career by assembling a band. After a few unsuccessful attempts at securing a recording contract, the group eventually released their first album, Frehley's Comet, on July 7, 1987. Frehley's Comet, a mixture of hard rock and pop metal, was a successful return to the music scene for Frehley. Despite the positive reviews and healthy album sales of Frehley's Comet, Frehley was unable to maintain much commercial momentum. On February 28, 1996, the original members of Kiss appeared (in full makeup and costumes) at the Grammy Awards to a standing ovation. On April 16, Kiss officially announced their reunion and plans for a tour during a press conference. Kiss took a break until early 2000, when Frehley re-signed to join them for a final tour—the Farewell Tour, beginning March 11, 2000. Frehley, expecting that the tour would be Kiss' last, chose not to remain in the band when it ended. His last performance with Kiss was on February 24, 2002. His most recent album Anomaly was released on September 15, 2009. This date was chosen as it was three years since he had confronted his alcohol problem and stopped drinking.
