Andrei Aleksandrovich Chadov was born on May 22, 1980, in Solntsevo, a suburb of Moscow, USSR, to a family that would later face the loss of their father, Aleksandr Chadov, in 1986. Following his father's passing, Andrei and his younger brother, Aleksey Chadov, were raised by their mother, Galina Petrovna Chadova, who played a multifaceted role in their lives as an engineer turned accountant and teacher.
As a result of their parents' divorce, the Chadov brothers were brought up as close friends, sharing a strong bond that would last a lifetime. Despite not being twins, the brothers shared a striking resemblance, with a 16-month age gap between them. This unique relationship allowed them to develop a strong sense of camaraderie, which would later translate into a successful professional partnership.
Andrei Chadov's early interest in acting was sparked during his school years, where he began performing in various classical and contemporary plays. He continued to hone his craft as an amateur actor at the municipal theatre-studio in Peredelkino, under the guidance of his first acting teacher, Aleksei Kozhikhin.
After completing his secondary education, Andrei enrolled in the Shchukin Acting School, but later transferred to the Shchepkin Theatrical School in Moscow, where he studied acting under the tutelage of Vladimir Seleznyov. He graduated as an actor in 2003, marking the beginning of his professional acting career.
Andrei Chadov made his film debut in a supporting role in the 2001 film "Lavina" directed by Ivan Solovov, while still a student. He went on to co-star with his brother in the 2006 film "Zhivoi".
