Students at Lakeside Park Elementary School in Hendersonville have been collecting their lunch trays from the kitchen and carrying them back to their classrooms to eat, after the cafeteria's air conditioning unit stopped working at the start of the school year. With temperatures nearing 100 degrees this week, Sumner County Schools has turned to portable A/C units in the kitchen while it waits on parts to fix the system for good.
The district's maintenance team is centrally monitoring HVAC systems online across its buildings, a network that tracks temperatures and system efficiency and allows officials to identify issues quickly and dispatch crews, as reported by WSMV. Even so, cafeteria repairs at Lakeside Park are expected to take at least another month, since the necessary HVAC parts are custom-made and may take up to a month to arrive and be installed. In the meantime, the temporary cafeteria units are meant to keep the environment comfortable for staff and students until the permanent fix is complete.
A Second-Grade Mom's Take on the Workaround
Marie Sansom, whose daughter is in second grade at Lakeside Park, said her daughter experienced two classroom air conditioning outages last year and that the current lunch arrangement is working so far. She told the station the repairs should help keep all the children cool once they're finished. Older Sumner County school buildings are not well insulated and struggle to stay cool when temperatures spike, according to the same report.
Sumner County Schools Superintendent Dr. Scott Langford said maintenance teams have kept some of the district's HVAC systems running for 40 to 50 years, and that principals are allowed to alter recess schedules at their schools to help keep kids safe in extreme heat. The school board approved an $84,000 contract to replace four broken HVAC units, and the district expects those replacement units to arrive and be installed in about four weeks. According to Main Street Media of Tennessee, the board formally approved the $84,249 purchase order on its consent agenda during its August 18 meeting.
Not the District's First Heat-Related Shutdown This Year
This isn't the first time HVAC trouble has disrupted schooling in Sumner County this year. Beech High School was forced onto half-days and virtual learning in April after an ice storm damaged its cooling towers, leaving classrooms without central air during an early spring heat spike, per a report cited by Main Street Media of Tennessee. Lakeside Park's own gym received a new HVAC system after similar issues, suggesting the cafeteria breakdown fits a broader pattern rather than an isolated glitch.
Logan Nash, who has a son who recently started at Hendersonville High School, believes the district's maintenance issues may be tied to the age of its buildings. He said temperatures of 100 degrees are unsafe for students and that he's concerned similar air conditioning problems could occur at Hendersonville High School and other district schools. Nash said student safety should make HVAC repairs a high priority and that he wants long-term changes made soon, though he called the district's initial response encouraging.
Weighing Patch Jobs Against Multi-Million-Dollar Fixes
The math behind those long-term fixes is steep. During an April study session, Langford detailed district capital priorities, noting that complete HVAC replacements at individual middle or high school facilities can cost upwards of $3 million, a figure reported by Main Street Media of Tennessee. Langford has announced plans to create a special committee of school board and county commission members to plan future capital investments strategically, rather than continuing to patch failures building by building.
Sumner County Schools is the eighth-largest public school district in Tennessee, serving more than 30,000 students across roughly 50 buildings spanning 530 square miles north of Nashville, according to Ballotpedia. Lakeside Park Elementary itself, located at 204 Dolphus Drive, serves between about 330 and 358 Pre-K through fifth-grade students, per Niche. The scale helps explain why the maintenance team must monitor the needs of each school rather than treating any single HVAC failure in isolation.
The cafeteria breakdown also arrives on the heels of a rocky start to the school year. Weeks before the late-August heat wave, a cyber breach forced the district to delay the opening of the 2026 school year from August 4 to August 10, according to the Tennessee Education Report. That delay compressed the early-year calendar just as extreme heat set in.
The Research and Rules Behind the Heat Concerns
The stakes of keeping classrooms cool go beyond comfort. A 2018 study from the National Bureau of Economic Research, co-authored by Harvard researchers and based on 10 million student exam retakes, found that without air conditioning, a 1-degree increase in average school-year temperature reduces learning by 1 percent, while full air conditioning offsets nearly 80 percent of that impact. Nationally, a 2020 U.S. Government Accountability Office report estimated that 41 percent of public school districts need to update or replace HVAC systems in at least half of their schools, affecting roughly 36,000 buildings, with HVAC equipment cited as the single most common major facility system needing repair.
Outdoor activities face their own heat thresholds. Under Tennessee Secondary School Athletic Association rules, outdoor practices and competitions must stop once the heat index tops 104 degrees, and mandatory 10-minute water breaks every 30 minutes kick in once the heat index reaches between 95 and 99 degrees. Tennessee Code Annotated § 49-6-3001 also mandates compulsory attendance for children ages 6 to 17, a legal backdrop that puts pressure on districts to keep classrooms safe and habitable during the school day.
