How did you heat an cool your home when you were a child?

I talked about this a little bit in a previous post but here goes.  In the winter, we had a coal furnace in the basement and registers in each room.  Hot water came from the furnace and circulated through all of the registers providing a steady warmth without blowing dust all over.  In the summer, we had fans.  No central air conditioning.  Nobody had AC since it wasn't invented yet or at least not in the town we lived in.  Later, there would be AC in theatres and stores but not in private homes.  We lived in the midwest so we needed heat in winter more than AC in summer.  We would have some real heat waves  but apparently we knew how to cope.  The cars, in summer, were a much bigger problem.  They only had 4 x 60 AC which meant four windows rolled down and traveling sixty mph.  I would look pretty good when I left the house but by the time I arrived I would be sweaty and windblown.  Not a good look.  The winter wasn't as bad since the cars had heaters not as efficient and now but capable of keeping us from freezing once the engine warmed up and could transfer some of that heat to the occupants.
My sister and I slept upstairs in a room over the kitchen.  For some reason, even though we had a register, it was never warm in the winter.  We would keep a pan of water on the register and when it froze, we slept downstairs.  In the summer, it was great because we had windows on three sides and had cool night breezes without the need of a fan. 
Is is amazing what you can live without if you don't know it exists and have never experienced it.  Besides air conditioning, we lived without computers, televisions and cel phones.  I still can live without the cel phone, iPod, blackberry and whatever comes attached to childrens and adults ears.
