Both of us are inexperienced when it comes to these systems, but fairly mechanically capable. Ultimately I have a few questions: - Are the trans air systems in the rear of the bus worth keeping (knowing they are run by the bus's engine)?
- How common are leaks and is this what causing the light to come on?
- Is it possible to keep just one?
- How complicated is the removal process?
- Is it possible to get them to run off of shore power in addition to the motor?
- Is there a common go to for air conditioning with skoolie conversions?

It would seem that most people remove installed AC systems for a number of reasons.
They often don't work. HVAC work is expensive, and many school districts don't do it. PArts, when you can get them, cost a fortune.
They only cool when the engine is running. They are rated to cool a tin can rolling along in 100+ temperatures, so they are costing quite a bit in diesel to run them.
They take up a large amount of space that can be put to better use.
When you have stripped and insulated the bus you have a much smaller cooling requirement, and a two-zone mini-split can do that job whether moving or on shore-power.
You generally can't use AC while boon-docking, unless you have enormous battery storage and a solar array costing thousands. An inverter generator would work, and be much cheaper and quieter.
If you buy a SPED bus the chances are you will have extra work removing the AC, but fewer seats to remove. Activity buses designed for highway use will probably have it too ... but again, most folk would remove it.
