My neighbor's window AC does too - May through most of October. In upstate NY. When I get my lawn mower out of my shed, which is close to the property line, it's always on. Day or night, cool or warm. And the house is almost completely shaded by huge maples!
There's also a guy that lives somewhere nearby (not sure if it's on the same road I live on) that goes by my house - in his late 90s dark green Chrysler mini-van - at least a half-dozen times a day. Sometimes more often. Sometimes he's alone, sometimes has a passenger. Looks to be retirement age, doesn't drive real fast. He goes by so often I can now recognize the sound of the car engine before he's even in sight. If he drives by my house this often while I'm outside working in the garden, how many more times do I miss when I'm inside or not home?
Soooo glad I don't have my neighbor's electric bill or the older guy's gasoline bill!
