CARY, N.C. (WTVD) -- It's the final days of summer for Ashkan Hosseini and his family before his two kids head back to the classroom.

"We're feeling good. It's special because our youngest is entering into kindergarten, so end of an era. But feeling good, they're both going to be at the same school," he said.

Both of Hosseini's kids are attending Hunter Magnet Elementary School, where, from time to time, the building is showing its age.

"I remember last year, my son in his first grade class, it was always warm, so definitely and humid, actually, being in an old building. So definitely hear it. It's one of those things that gives the kids some grit. But would I like them to be more comfortable? Yeah, absolutely," he said.

The Wake County chapter of the North Carolina Association of Educators (NCAE) said on Thursday that the school district needs to do better about figuring out costs and a plan to fix A/C, ventilation, and heating in the classroom.

"These are not minor inconveniences. There are unsafe conditions that make teaching and learning almost impossible. We need a bond that actually covers the full cost of these problems," said Enloe High social studies teacher Jeff Fuse. "Anything less just guarantees that students and educators will keep suffering in unsafe buildings."

Right now, the county is considering an approximately $700 million bond for the school system, but the NCAE is concerned that it's not nearly enough, especially considering the Wake County Public School System (WCPSS) has almost that amount in deferred maintenance alone.

"We have the resources in Wake County. We just need the political will. This is a once-in-a-lifetime, once-in-a-generation chance to fix our facilities for good," said Wake NCAE President Christina Cole.

In response, Wake County Schools told ABC11 that a third-party firm will evaluate all school facilities over the next few months, as part of a required assessment by the state Department of Public Instruction to help figure out exact costs. It is also looking at a pay study to see what they need to compete for qualified HVAC technicians they need to hire.

But a bond is something parents say would be worth it to keep the classrooms safe and ready to go.

"Absolutely, I think people would support anything education related," Hosseini said.
