The air conditioning at the AT&T Center in San Antonio was out of service Thursday night during Game 1 of the NBA Finals.

A statement on behalf of the Spurs Sports and Entertainment said the outage was due to an electrical failure to the power that runs the AC system for the arena.

Crews were working to restore the power to the air conditioning system.

Game 2 of the Finals between the Spurs and Heat will be Sunday at 8 p.m. on Local 10.
