The South Carolina Department of Education reported that approximately 45 air-conditioning concerns have been logged in the Charleston area since the start of the 2026-27 school year, part of a broader statewide wave of bus cooling failures officials say is tied to record heat and humidity.
Scope of the problem
Statewide, the department said about 680 air-conditioning issues have been reported, representing roughly 12% of South Carolina's state-owned school bus fleet. Of those reports, 405 were confirmed to involve mechanical or operational problems requiring corrective action. As of Friday afternoon, 275 remained in various stages of diagnosis, repair or parts replacement.
The department noted that typically about 2% to 3% of the fleet is under repair at any one time and said the current, higher rate points to the additional strain caused by extreme heat and humidity coinciding with the start of classes.
Local reaction and district response
Parents in the Lowcountry have reported children arriving home from buses sweaty and uncomfortable. Some parents told local reporters that students were distressed after rides without working cooling systems.
Charleston County School District officials said the worst problems have been on state-owned buses. The district received authorization from the state to begin repairs on those vehicles and advised drivers to keep windows open to increase airflow while encouraging students to stay hydrated.
"Every student deserves safe and reliable transportation to and from school,"
the Department of Education said in a statement, adding that it is working urgently to address reported issues.
What the numbers mean for families and operations
- 45 reported AC concerns in the Charleston area since the school year began.
- 680 AC concerns statewide; about 12% of state-owned buses affected.
- 405 of those statewide confirmed as needing corrective action; 275 still in repair or diagnosis.
District officials emphasized precautions for student safety while repairs are made. Those measures include keeping windows lowered on buses without functioning air conditioning and reminding students to carry water and avoid overheating. The department did not provide a timeline for when all affected buses would be returned to full service.
Implications and context
School transportation is a daily lifeline for many Charleston families, and prolonged mechanical problems during a heat wave raise questions about maintenance capacity, parts availability and scheduling. The higher-than-normal rate of AC failures — compared with the usual 2% to 3% undergoing repairs — underscores how environmental factors can overwhelm routine maintenance cycles.
Until buses are repaired, parents and guardians are left weighing options such as alternate drop-offs, earlier pick-ups, or arranging personal transportation when feasible. For families without alternatives, continued communication with the school district about bus conditions and expected repair timelines remains essential.
| Measure | Figure |
|---|---|
| Charleston-area AC reports | 45 |
| Statewide AC reports | 680 |
| Confirmed repairs needed | 405 |
| Still in repair/diagnosis | 275 |
School leaders said they are coordinating with the State Department of Education to prioritize repairs and keep families informed. With summer-like temperatures persisting, the district reiterated the need for vigilance to protect children riding buses until cooling systems are fully restored.
