Dayton, Ohio – Horizon Science Academy High School Cancels Classes Due to Air Conditioning Failures
Horizon Science Academy High School, a charter school located in Dayton, Ohio, announced the cancellation of classes scheduled for Monday, August 18, 2025, citing ongoing issues with its air conditioning system. This decision marks the second consecutive day of school closures for the institution related to the same problem.
Initial Closure and Confirmed Cancellation
The school first canceled classes on Friday, August 15, 2025, due to the air conditioning malfunction that affected the building’s climate control system. The inconvenience prompted the school administration to suspend activities in order to prioritize student and staff comfort, as well as safety concerns associated with the high indoor temperatures. On the morning of Monday, August 18, the school publicly announced via its website that classes would remain canceled for the day, citing unresolved technical issues with the HVAC system.
Location and Contact
The school is situated at 250 Shoup Mill Road in Dayton, Ohio. Authorities and parents were informed early on Monday through the school’s official communication channels. The timing of the announcement was intended to provide notification well in advance of the usual start of the school day, allowing families and staff to adjust their plans accordingly.
Investigation and Ongoing Updates
In addition to the school’s own announcement, local media outlets have reported that efforts are underway to determine whether classes will resume on Tuesday, August 19.
