The team competes in USL League Two, the fourth tier of the American Soccer Pyramid, as a member of the Lone Star Division.

Laredo Heat initially joined the USL Premier Development League in 2004 as an expansion franchise, playing a limited 'exploratory' schedule of eight exhibition games against selected opponents, but only managed two wins, both over the Lafayette Swamp Cats, 4–0 and 5–0, the latter of which featured a hat trick from striker Nelson Mata-Meza.

Former Tampa Bay Mutiny, D.C. United and US national team striker Roy Lassiter played for Laredo in their 2–1 loss to DFW Tornados, but did not get on the score sheet.

The Heat decided to opt out of the PDL's 2016 season, citing the slow growth of the Mid-South Division as the reason.
