We just moved to TV after 30 years and 300 miles further south. Our builder grade air conditioner was 20 years old when we replaced it with a Trane. When we would go away for several months in the summer, the only thing we left on was the air conditioner at 79 degrees. Our electric bill, for each month we were gone, was a whopping $13.28 cents and that was with the old 20 year old Rudd. We only replaced it because at 20 years, we were afraid it might die on us, while we were away. I was always told 12 years is the max, but I'm not sure any more.
