Tucson Unified School District says they've resolved cooling problems with some schools heading into the first day of school.
Tolson had no cooling as of 7:05 Thursday morning, because of the combination of a brownout and a loose belt in a cooling tower, but officials say the cooling was restored by 9:30 a.m. and they will replace the new belt as soon as it arrives.
Five classrooms had to be moved to areas with cooling at Pistor, Maldonado, Ochoa, Robins and Bonillas.
Seven sites had portable cooling delivered to offset the heat.
Those sites are Cragin, Davis, Grijalva, Miles, Dietz, Sewell and Bonillas.
When school is in session -- the cooling is set to around 76 degrees. It is 85 degrees when the schools are unoccupied.
Cholla had no immediate issues today. District officials say the school was never without cooling. They will be replacing a cooling tower at the school later in August.
