As a player Heimir started playing for ÍBV from his local town Vestmannaeyjar in 1986. He played with them until 1996 except for the 1993 season in which he played for Höttur while managing their women's team. From 1996 until 2007 he played lower league football with another club from Vestmannaeyjar, from 1996 to 1997 he played with Smástund and from 1998 with KFS, the merged team of Smástund and another lower league team from Vestmannaeyjar called Framherjar. From 2002 to 2007 his appearances were sporadic. Throughout his playing career, he also served as the dentist for his home village, and even after taking sole reign over the Icelandic national team after Euro 2016 continues to practice part-time.
I still have my clinic and I like to keep my fingers working. So I try to go there as much as I can in my spare time and do some dentistry. Some coaches go and play golf, I do dentistry. The reality of a football coach, you never know when you are out of a job so it’s good to have another profession to jump into.
In the same interview, Heimir also revealed that in the summer of 2017, he cared for a player who had a tooth knocked out at a local women's game he was attending, going on the pitch while the player was knocked unconscious and putting the tooth back in place, and then personally making the necessary tooth repair at a nearby dental office.
In 1993, while playing with the men's senior team of Höttur, he coached their women's team, helping the team come first in the second tier and achieve promotion. Alongside working as a dentist in Vestmannaeyjar he started coaching the town's women's senior team, ÍBV, guiding them towards the top of the Icelandic women's Premier league, gaining places in the table each year. In 2002, he was hired as assistant manager for the men's team of ÍBV, being their manager for the last games of the season after the manager was fired. In 2003, he again took over the women's team, guiding them to two 2nd-place finishes in the league and two cup finals, with ÍBV winning the second one in 2004. He then didn't manage any club in 2005 but again took over as the manager for the ÍBV men team mid-season in 2006, managing the team in the last 6 matches but failing to prevent relegation. He remained this time as manager and got promoted with the team in the 2008 season, finishing 10th out of 12 in the top division in 2009 before managing two 3rd-place finishes in a row in 2010 and 2011.
On 14 October 2011, KSÍ announced they had appointed Heimir as assistant manager of the Iceland national football team alongside Lars Lagerbäck as manager. Iceland qualified for the play-off stage of the 2014 FIFA World Cup qualification, however, Iceland lost there against Croatia. Shortly thereafter Heimir and Lagerbäck signed a new contract, this time as joint managers. Heimir became the sole manager following Euro 2016, with Lagerbäck becoming manager of Norway.
