Hi, Kennie1933. Thanks for sharing your personal experience with AC. I'm sure a lot of us, including me, have thought the same. But the fact is, if it were as simple as installing cheap home ACs, this issue would be moot. But the problem of ACing a part of a home vs. classrooms in a school is very different. We're looking at not only the AC system but the school's infrastructure. We're also looking at runaway energy costs, long-term sustainability, and maintenance. There's a lot of literature out there about the issues involved in installing a reliable, efficient, cost-effective AC system in our schools. The complexity translates to high bids. Thus the renewed call for lower bids. The fact that we've found a solution that makes sense is reassuring. And it didn't just happen. It required leadership.
