Kiessling's piece Temptation Sensation (originally titled Haute Couture) is the theme song for It's Always Sunny in Philadelphia, the longest-running live-action sitcom in American television history. The series also uses background music during its episodes from Kiessling, including On your Bike and Blue Blood (originally titled Tandem-Holiday and Pizzicata Milanese respectively).

Soon after, he started working on recording music for television. In 1950, he began composing music in the jazz, dance, and light music genres. At times, he also led his own orchestra, and also worked many years for the in Berlin. Together with the pianist Werner Tautz, he established in 1964 the label "Brilliant" through which he managed numerous national and international big bands.

Kiessling worked with many national and international stars, including Chet Baker, Luis Bonfa, Wenche Myhre, and Caterina Valente. For over two decades, he accompanied the shows of Peter Alexander. In addition, Kiessling composed the songs and scene music for numerous films and television productions, including , Zwei himmlische Töchter, , Das Traumschiff and Aktenzeichen XY... ungelöst. In total he produced over 1200 tunes and also published some of his own recordings which made him become one of the most successful German "easy listening" composers of the post-war period.

Notable works In 1969, Kiessling wrote "In the Shadow of the Moon" for Reprise, which later on became the theme song for Frank Sinatra's daughter Tina Sinatra TV mini-series Romeo und Julia '70.

His piece "Temptation Sensation" is used as the theme song for the FX and FXX TV show It's Always Sunny in Philadelphia. Always Sunny cast member Charlie Day told Entertainment Weekly that the original pilot of the show took place in Los Angeles and the theme song used to be a cha-cha version of "Hooray for Hollywood". "FX loved the show, but wanted to take it out of the entertainment industry", Day explained. "We had a music supervisor called Ray Espinola and we said, 'Give us everything you have in a sort of Leave It to Beaver with a big-band swing kind of feel', and the majority of the songs are from what he sent over. When you set it against what these characters were doing - which oftentimes can be perceived as quite despicable, or wrong - it really disarmed the audience. It just became our go-to library of songs."
