The central heating and air conditioning works great in that room normally
I teach science off hours to high school students that need extra help with the subject. I operate out of my home and do this every other night a week. One of the things that I always make sure is in place is that the room that I teach in has the best and most proper temperature control so that I feel much more relaxed and so the kids that I am helping can concentrate more. I always make sure that I have both a portable air conditioning system and a portable space heater on hand in the event that the central heating and air conditioning system was to break down while I was teaching a science lesson. That way, I would not have to cancel the class and the kids can get the most out of their extra help that they need with me teaching this subject after hours during the week. The central heating and air conditioning works great in that room normally. But one time when I had an unexpected HVAC break down, I had to cancel my science class for the day and the kids that were scheduled to come were behind in their studies. Ever since that day is when I came up with the idea to make sure and have a portable air conditioning system on hand as well as a portable space heater. So if it ever goes out again on those days, I can still do my classes as per normal! It is a good method and it is safe and it works well.
