But, that was the situation at Green Elementary in Raleigh.
A problem with the building's cooling system left much of the building without AC.
Parent Becky Johnson told ABC11 air temperatures were too hot for her daughter to be in school.
"If it gets too hot or she over exercises, she could have an asthma attack [and] end up in the hospital having trouble breathing, not breathing. Your lungs constrict and they can't pull the air in or push the air out," she said.
"It felt more hot than it was outside," said Johnson's daughter Kayla.
Maintenance workers were able to get the air conditioning in the school working again Wednesday afternoon.
