In my classroom the HVAC constantly blows way too much air from the room-width ceiling vent directly above the blackboard. It's a really noisy air-rushing sound.
Also the temperature gets too hot, then gets too cold, then gets too hot, then gets too cold over and over, all the while blowing way too much air from the room width ceiling vent directly above the blackboard.
In fact even when it's not heating or cooling, the air still blasts from the ceiling vents directly above the blackboard.
There is a Johnson Controls T-4002 and I can hear it cycle on and off.
If I could cut way down on the air blasting me, that would be great!
If I could stop the HVAC from cycling hot / cold that would be great!
Maintenance says there is nothing they can do although they did close up the nozzles on the ceiling vent, but this only made the air-rushing sound louder and did not do much to reduce air blasting.
There is another room-width ceiling vent that acts just the same at the back of the classroom.
I have checked the rooms adjacent to my classroom, they are much quieter and the temperature does not vary to such an extreme.
There has got to be a way to stop the air blasting and the air noise, plus get the temperature constant!
Right?

Balance the ductwork.

Control the fan. Ensure the unit is sized properly.

Wire the fan to run automatically, the way it was designed.

Tell your school's administrator they need to hire an HVAC specialist. Tell them your taxes should provide you with a comfortable and quiet learning environment. Tell them to fix the problem or relocate the class. Problem solved.
