May I turn on the heat through an A/C system on Shabbat? Is there a difference between turning it on, turning it off and adjusting the temperature while it’s already running?

If you forgot to put it on before Shabbat, then turn it on Kilachar Yad.
I understand Kilachar Yad means doing it in an unusual way, with the back of the hand. What I don’t understand is what difference that makes if the action and the intention are the same. What is the point of doing the melacha in an abnormal way? Why not just do it the normal way?
Also, what other things on Shabbat have to be done this way? I think you once mentioned an elevator as an example, but I am not sure.
