Teacher's viral video shows classroom coated in mold after school reportedly cut AC over summer

"I'm assuming that whole building (literally every surface including air ducts) needs to be sanitized and de-molded."

After summer break, a teacher returned to find her classroom covered in mold — including books, posters, furniture, and other supplies. The video struck a nerve for many viewers, highlighting how easily schools can fail both educators and the learning environments students depend on.

Here's what to know

Alyssa went to TikTok with a video showing mold had spread throughout her classroom. As CafeMom reported, she said the school had shut off the air conditioning over the summer, leaving her with an unsafe room and damaged materials, some of which she paid for herself.

The clip that has since been removed, titled "First day in my classroom… plot twist: everything's moldy," showcased mold on books, picture frames, wall posters, chairs, desks, and an ottoman. Alyssa captured the frustration many teachers feel, saying, "This is the reason that no one gets into education."

The story spread further after an Aug. 5, 2026 post on X amplified the clip, claiming that Alyssa may have been fired after the video went viral. While that claim remains unverified, the reaction online was swift and intense.

More background

Teachers often spend their own money on classroom necessities, which made the reported damage even more upsetting to so many viewers.

One commenter wrote, "I can confirm her claim. When I taught, we got $100 per year to buy classroom supplies. It's bull s***. If a classroom looks well decorated and happy, the teacher did it with her own money." 

Another added, "That is terrible. I do agree teachers do not get paid enough."

Money aside, the health implications rightfully became a major part of the conversation. Mold is not just unsightly — it can affect air quality and trigger respiratory issues in a room where children are expected to spend hours each day.

One person expressed their concern, commenting, "I'm assuming that whole building (literally every surface including air ducts) needs to be sanitized and de-molded… she better sue and get a hefty check."

What can be done?

Routine building maintenance, summer HVAC planning, and clear indoor air quality standards before students and staff return can help prevent mold damage and unsafe classrooms. Cutting costs by shutting off cooling systems can create even bigger, more expensive problems if it leads to mold damage like Alyssa's classroom.

A retired teacher wrote, "I understand this teacher's issues! Without air — everything gets ruined, and I feel horrible for her. Her working conditions are unexcusable! Why do teachers have to spend a fortune on getting their rooms ready?"

Donations can help replace ruined items more quickly, though that does not excuse systemic neglect.
