Most schools in the Naperville area have A/C. I haven't heard one school that doesn't. It will also depend on the age of the building. All the newer schools will have A/C. The old ones may not and there might not be a way to structurally add A/C.
Surprisingly, new does not mean schools have air conditioning. In Naperville 204 there are 21 Elementary schools, and only two (Owen and Peterson) have air conditioning. All of the other schools operate a specific plan to insure safe and conducive learning on warm days. If you would like additional information, please feel free to contact me.
Hi jblair, with these taxes they better have!! I know when I grew up we probably did not but the great news is that today Naperville schools have air and so much more to offer. On a serious note we have one of the best districts and that is what matters most. Hope this helps.
