Are you a guy who likes to go out and get all the latest gadgets? Or do you prefer to hang back and let other people spend the high prices while you just watch and see what happens? Personally, I am the ladder, and I am not quick to embrace any kind of technology, much less heating and A/C technology.
That being said, I have various siblings who are both into gadgetry and technology, and they both have all kinds of heating and A/C technology that I do not have.
Both of them have what is called heating and A/C with zone control. Heating and A/C with zone control means that you set your air conditioner unit up so that your condo is cut into different areas, called zones, and each one of those zones can be controlled separately from the others. In other words, you can use less air conditioner in a room that does not have people in it for example. To illustrate, both of my siblings have three story houses. Both have large homes, then yet one sibling lives with only his wife, and the other sibling lives only by himself. Therefore, it makes great sense to turn the air conditioner off on whatever floor you are not using. At least, you can turn the control unit setting up a few degrees on whichever floor does not get the most use. That will normally be the ground floor of course. However, when I go to visit my sibling, I normally stay in an upstairs home office, which means he has to control the control unit on the next floor. Even within the zone of the top floor, he can make the AC temperature lower in just my home office than it is in the other home offices. It’s absolutely kind of amazing.
