I grew up that way as well, except for the party line. The area we lived in had discontinued them by that point.
No a.c., had an attic fan. If we had a box or tabletop fan I dont recall, but I dont think we did.
We didnt have a tv until about 1973, and that was a second hand one my mother was given. We were all the remote, and I remember tin foil on the rabbit ears!
For entertainment, we had an am/fm radio that plugged in, sat in the living room. Seems that it was on all the time, tuned to the main top 40 hits channel, I think 104FM, or maybe it was KILT FM100. Played all the rock hits, over and over.
We mostly played outside after school and weekends. Winters were generally very mild so we could even be outside then.
We had toys, board games, my brothers had bikes, they did some limited sports at school, etc.
Mom worked all the time but was home every evening and on Sundays, dad was simply not there 99% of the time. We were on our own a lot but had the sense not to do stupid, dangerous things.
It was generally a good childhood. Not perfect. But its better to forget the crappy times and focus on good memories.
