Okay, I didn't find a section that this really fits in but it is definitely worth posting:
There are gaskets and stuff inside air conditioners that need to be moistened by pressurization of the liquid inside every so often.
If you don't pressurize the unit once or twice during the winter, the gaskets can dry out and leak by the time you use it next.
Its not a big deal. Just turn on your air conditioner (home and/ or auto) for a couple minutes every couple months.
It will enable them to last a lot longer.
I'm not saying how much longer because it may jinx me, but its a LOT.
