Parts of Greenbrier Middle School had no working central air conditioning as Middle Tennessee's heat index climbed as high as 105 degrees Fahrenheit on Monday, forcing the school to lean on portable AC units to keep students and staff cool. Robertson County Schools officials confirmed that eight to ten classrooms at the school routinely lose air conditioning, and said a full replacement of the cooling system will not happen until the start of the next school year.
The outage came just days into the 2026-27 school year, according to WSMV, which reported that several rooms at the Greenbrier, Tennessee campus were using portable AC units while a heat advisory remained in effect across Middle Tennessee until 7 p.m. Monday. Afternoon highs in the mid-90s combined with humidity to push the heat index into the triple digits, the outlet reported. As reported by WKRN-TV, Robertson County Schools officials confirmed that eight to ten classrooms at Greenbrier Middle School routinely lose air conditioning, and said the district does not expect a full system replacement until the 2027-28 school year begins.
Robertson County Schools said its Buildings and Grounds Department is aware of the current status at Greenbrier Middle School and is monitoring building and room temperatures there, as well as at every school in the district, throughout each day, per WSMV. Workers were on-site Monday waiting on delivery and installation of a portable AC system for the school's gym, the district told the outlet, and the plan is to keep using portable units until the central AC situation is resolved.
A Recurring Maintenance Headache
This is not the first time cooling problems have surfaced at the school. Minutes from a September 2025 Robertson County Board of Education meeting, published by Citizen Portal, show board members questioning administrators about an outstanding work order for a non-functioning air-conditioning unit in the school's seventh-grade hallway. That record suggests the district's cooling troubles at Greenbrier Middle predate this week's heat wave by nearly a year.
The district has previously put money toward HVAC fixes districtwide. Federal ESSER pandemic relief funds were allocated for a major facility renovation at Greenbrier Middle School to address deferred infrastructure maintenance, along with HVAC replacements at three other campuses, according to Robertson County Schools' own compliance documentation. Separately, Main Street Media of Tennessee reported that the school board approved a 2022 operating budget that set aside $1 million specifically for districtwide HVAC repairs and replacements. Robertson County Schools' Buildings and Grounds Department, which handles maintenance, electrical, plumbing and HVAC work, employs 21 staff members responsible for all 23 facilities in the district.
State Rules Govern Heat and Recess
Tennessee has statewide guidance for exactly this kind of scenario. The Tennessee Department of Education's Office of Coordinated School Health instructs principals to move outdoor recess and physical education indoors whenever outdoor temperatures hit 95 degrees or higher. For school sports, the Tennessee Secondary School Athletic Association requires outdoor practices to be capped at one hour with 20 minutes of mandatory rest when the heat index sits between 100 and 104 degrees, and mandates a complete cancellation of outdoor practices once the heat index tops 104 degrees.
Tennessee law also gives districts some flexibility if extreme heat forces closures. Under Tennessee Code Annotated § 49-6-3004, districts that add 30 minutes to their daily instructional time can bank up to 13 excess instructional days a year to offset days lost to dangerous weather or severe illness. It remains unclear whether Robertson County Schools would consider early dismissals or weather-day allowances at Greenbrier Middle if the portable units fail to keep room temperatures within safe limits, and the district has not addressed that possibility publicly.
Part of a Wider Pattern
Greenbrier Middle School enrolls roughly 558 to 602 students across grades 6 through 8, according to National Center for Education Statistics figures cited by Ballotpedia. The struggle to keep those students cool mirrors a broader problem facing schools well beyond Robertson County. Hoodline previously reported on a similar scramble at Nash County Public Schools in North Carolina, where multiple campuses faced widespread AC failures during mid-August triple-digit heat waves that forced emergency deployments of portable cooling units.
For now, Robertson County Schools is banking on portable units to bridge the gap at Greenbrier Middle School while the district works toward the promised system overhaul next year. Families and staff at the Greenbrier, Tennessee campus are left navigating a mix of hallway heat, gym cooling repairs, and daily temperature monitoring until then.
