AUSTIN, Texas — McCallum High School in central Austin sent out a plea for portable fans on Thursday after the high school experienced severe air conditioning issues.

In a letter to families on Thursday, Principal Andy Baxa said that multiple portables and classrooms across campus were without working A/C.

The school said that they were working with Austin ISD officials to address the issues with the A/C, and that several fixes had been made; however, the remaining issues would take “a little longer” to complete.

McCallum requested donations of quiet or “whisper-mode” portable fans to help keep students cool. Teachers at the high school brought personal fans from home, but the school said that those units were not enough to keep a full classroom comfortable in the extreme heat.

As of Friday morning, the school says it has received 23 fans. Austin ISD maintenance and construction teams are working on repairs to the air conditioning.

The plea for fans came as central Texas experiences a heat advisory and one of its driest Augusts on record.

Those who would like to donate fans may drop them off at the front office of the high school. You can also ship a fan bought online, the school asking those who do to deliver them directly to McCallum High School, Attn: Front Office; 5600 Sunshine Dr., Austin, TX 78756.
