The perfect timing of converting the Heating and Air Conditioning systems from A/C to Heat or vice versa is a gamble, at best. Although long range forecasts predict cold morning temperatures or hot afternoons, it is the range between these two extremes which causes you/us the most calls.
Once Central HVAC Systems are converted, they cannot be “switched back”, unless failure to do so could result in equipment damage, and thus the Principal’s decision represents a “total commitment”. For example, moving too soon from A/C to heating will mean hot classrooms in the afternoon but comfortable classrooms in the morning. Of course, having comfortable classrooms in the morning adds even more heat to that “hot” classroom in the afternoon. Obviously, delaying the conversion will result in the reverse comfort levels.
The Principal will decide when to convert their facility: send an e-mail to the Maintenance Director with a copy to the Facilities Director.
